GlideForm (g_form) - Client

  • リリースバージョン: Australia
  • 更新日 2026年03月12日
  • 所要時間:110分
  • The GlideForm API provides methods to customize forms.

    Only use GlideForm methods on the client. You can use these methods to make custom changes to the form view of records. All validation of examples was done using client scripts.

    You can also use some of these methods in other client scripts (such as Catalog Client Scripts or Wizard Client Scripts), but you must first test this to determine whether they will work as expected.

    注:
    The methods getControl(), getHelpTextControl(), getElement(), and getFormElement() are deprecated for mobile devices. For information on using GlideForm for mobile, see Mobile Client GlideForm (g_form) Scripting and Migration.

    There is no constructor for the GlideForm class. Access GlideForm methods using the g_form global object.

    The following example script demonstrates how to call g_form.getOptions() with getAvailable() function.

    const options = g_form.getOptions('priority');
    if (options) {
      console.log('Selected:', options.selected);
      options.getAvailable('high').then(available => {
        console.log('Available matching "high":', available);
      });
    }

    GlideForm - getReference(String fieldName, Function callBack)

    Returns the GlideRecord for a specified field.

    If a callback function is present, this routine runs asynchronously. The browser (and script) processing continues normally until the server returns the reference value, at which time, the callback function is invoked. If a callback function is not present, this routine runs synchronously and processing halts (causing the browser to appear to hang) while waiting on a server response.

    重要:
    It is strongly recommended that you use a callback function.

    Callback function support for ServiceCatalogForm.getReference is available.

    注:
    Using this method requires a call to the server which requires additional time and may introduce latency to your page. Use this method with caution. For additional information, see Client script design and processing.
    表 : 75. Parameters
    Name Type Description
    fieldName String Name of the field.
    callBack Function Name of the call back function.
    表 : 76. Returns
    Type Description

    If the specified reference can't be found, it returns an initialized GlideRecord object where currentRow = -1 and rows.length = 0.

    function onChange(control, oldValue, newValue, isLoading) {
        g_form.getReference('caller_id', doAlert); // doAlert is our callback function
    }
     
    function doAlert(caller) { // reference is passed into callback as first arguments
       if (caller.getValue('vip') == 'true') {
          alert('Caller is a VIP!');
       }
    }

    GlideForm - getRelatedListNames()

    Returns an array of related list names from the current form.

    None
    表 : 82. Returns
    Type Description
    Array of HTML elements Form's sections.
    function onChange(control, oldValue, newValue, isLoading) {
       //this example was run on a form divided into sections (Change form)
       // and hid a section when the "state" field was changed
       var sections = g_form.getSections();
       if (newValue == '2') {
          g_form.setSectionDisplay(sections[1], false);
       } else {
          g_form.setSectionDisplay(sections[1], true);
       }
    }

    GlideForm - getTableName()

    Returns the name of the table to which this record belongs.

    On the server side, the table for the current record can be retrieved with current.sys_class_name or current.getTableName().

    表 : 83. Parameters
    Name Type Description
    None
    表 : 84. Returns
    Type Description
    String Name of the table.
    function onLoad() {

       alert(incSysid);
    }

    GlideForm - getValue(String fieldName)

    Returns the value of the specified form field.

    This method also supports getting values from a multi-row variable set (MRVS). To obtain data from fields within an MRVS, you must first use JSON.parse(getValue('<mrvs_field_name>') || '[]') to obtain the MRVS array, and then use indexing to access the fields within the row objects. For more details, see the code example below.

    表 : 87. Parameters
    Name Type Description
    fieldName String Name of the field whose value to return.
    表 : 88. Returns
    Type Description
    String Value of the specified field.

    The following example shows how to get the short description from the current form.

    function onChange(control, oldValue, newValue, isLoading) {
       alert(g_form.getValue('short_description'));
    }

    The following example shows how to get values from an MRVS. In this example, salaries are being managed through the Service Catalog. The client script searches all rows within the MRVS for the value entered in the Job title and then updates the matching entries within the MRVS with what is entered in the Salary field. The MRVS is named "variable_set_1" and contains the following fields within each row object: Employee name [employee_name], Job title [employee_job_title], and Salary [employee_salary]. In addition, the Catalog Item contains: Job title [job_title] and Salary [salary].

    function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
    return;
    }
     
    // Get the MRVS
    var vs1 = g_form.getValue('variable_set_1') || '[]';
    var multiRowVariableSet = JSON.parse(vs1);
     
    for (var i = 0; i < multiRowVariableSet.length; i++) {
    // Check if the entered job title matches the title in the current MRVS row
      if (multiRowVariableSet[i].employee_job_title == g_form.getValue("job_title")){
        // Update the value of a matching field with the new salary
        multiRowVariableSet[i].employee_salary = newValue;
      }
    }
     
    // Update the MRVS
    g_form.setValue('variable_set_1', JSON.stringify(multiRowVariableSet));
    }

    Data type: String

    表 : 130. Returns
    Type Description
    Boolean Flag that indicates whether the option label is updated successfully.
    Valid values:
    • true: Choice label is updated.
    • false: Choice label isn't updated because the specified choice to update may have been read-only or does not exist, or the new label exists and is already associated with another option.

    The following example calls setChoiceLabel() to update the 'bonus' field choices (10, 20, and 30) to new values.

    // Show the calculated bonus next to the percentage label
    var salary = parseInt(g_form.getValue('salary'), 10); 
    g_form.setChoiceLabel('bonus', '10', '10% ($'+ (salary * .10) +')'); 
    g_form.setChoiceLabel('bonus', '20', '20% ($'+ (salary * .20) +')'); 
    g_form.setChoiceLabel('bonus', '30', '30% ($'+ (salary * .30) +')');

    GlideForm - setDisabled(String fieldName, Boolean disable)

    表 : 134. Returns
    Type Description
    void
    function onChange(control, oldValue, newValue, isLoading, isTemplate) {
       //If the page isn't loading
       if (!isLoading) {
          //If the new value isn't blank
          if (newValue != '') {
             g_form.setDisplay('priority', false);   
          }
          else 
             g_form.setDisplay('priority', true);
          }
       }

    GlideForm - setLabelOf(String fieldName, String label)

    Sets the plain text value of the specified field label.

    if (g_user.hasRole('itil')) {
        var oldLabel = g_form.getLabelOf('comments');
        g_form.setLabelOf('comments', oldLabel + ' (Customer visible)');
    }

    GlideForm - setMandatory(String fieldName, Boolean mandatory)

    Makes the specified field mandatory.

    Whenever possible, use a UI policy rather than this method.

    表 : 137. Parameters
    Name Type Description
    fieldName String Name of the field to make mandatory.
    mandatory Boolean Flag that indicates whether the field is mandatory.
    Valid values:
    • true: Field is mandatory.

    GlideForm - setReadOnly(String fieldName, Boolean readOnly)

    Makes the specified field read-only or editable.

    Whenever possible, use a UI policy instead of this method.

    To make a mandatory field read-only, you must first remove the mandatory requirement for that field by using the setMandatory() method.

    Once you set a field to read-only, you cannot use the setValue() method to update the value of that field. If you need to set the value in this way, you must set the readOnly value to false.

    表 : 139. Parameters
    Name Type Description
    fieldName String Name of the field whose access value to set.
    readOnly Boolean Flag that determines whether the associate field is editable or read-only.
    Valid values:
    • true: Set field to read-only.
    • false: Set field to be editable.
    表 : 140. Returns
    Type Description
    void

    The following example shows how set the Variable Editor to read only. To do this in Service Catalog tables, use setVariablesReadOnly().

    // Create a Client Script on a table (e.g., incident) and paste this script
    // Uncheck (set to false) the "isolate script" checkbox (not available by default)
    // To add the isolate script checkbox to the form, configure form layout to add the checkbox
    function onLoad() { 
      $("variable_map").querySelectorAll("item").forEach(function(item){
        var variable = item.getAttribute("qname"); 
        g_form.setReadOnly("variables."+ variable, true); 
      }); 
    }

    GlideForm - setRelatedLinksDisplay(Boolean display)

    Show or hide the Related Links section in the form UI using Boolean values.

    GlideForm - hideRelatedLinks() hides related link UI Actions on the form, while GlideForm - showRelatedLinks() shows them. The g_form.setRelatedLinksDisplay(boolean: display) method, however, can be used to either show or hide related links with more flexibility in your scripts.

    表 : 141. Parameters
    Name Type Description
    display Boolean Flag that indicates whether to show or hide the Related Links section of a form.
    Valid values:
    • true: Displays related links in the form.
    • false: Hides related links in the form.

    Default: true

    表 : 142. Returns
    Type Description
    None

    The following example demonstrates how to show or hide the Related Links section in a form.

    // Displays the Related Links section in the UI
    g_form.setRelatedLinksDisplay(true);
    // Hides the Related Links section in the UI
    g_form.setRelatedLinksDisplay(false);

    GlideForm - setSectionDisplay(String sectionName, Boolean display)

    Shows or hides a specified section in the form.

    表 : 143. Parameters
    Name Type Description
    sectionName String Section name is lower case with an underscore replacing the first space in the name, and with the remaining spaces being removed. For example, "Section Four is Here" becomes "section_fourishere". Other non-alphanumeric characters, such as ampersands (&), are removed. Section names can be found by using the getSectionNames() method.
    display Boolean Flag that indicates whether to show the section.
    Valid values:
    • true: Show the section.
    • false: Hide the section.
    表 : 144. Returns
    Type Description
    Boolean Returns true when successful.

    GlideForm - setValue(String fieldName, String value)

    Sets the value of a specified form field to the specified value.

    This method also supports setting values in a multi-row variable set (MRVS). You must first use JSON.parse(getValue('<mrvs_field_name>')) to obtain the MRVS array and then use indexing to update the fields within the row objects. Once all values are updated in the MRVS, use the setValue() method to save the updated MRVS array. For more details, see the code example below.

    On fields set to strict read only, this method does nothing when used and a warning is logged in the browser's console. For more information, see Configuring read-only security options.

    注:
    The method setValue() can cause a stack overflow when used in an OnChange client script. This is because every time the value is set, it will register as a change, which may re-trigger the OnChange client script. To prevent this, perform a check that will validate that the new value will be different from the old value. For example, before performing setValue(shortDesc, newValue.toUpperCase());, validate that the short description is not already uppercase. This will prevent the client script from applying the toUpperCase() more than once.
    表 : 145. Parameters
    Name Type Description
    fieldName String Name of the form field to update.
    value String Value to set in the specified field.
    注:
    When defining a value in a choice list, be sure to use the number value rather than the label.
    表 : 146. Returns
    Type Description
    void

    The following example shows how to set the short description in the current form.

    g_form.setValue('short_description', 'replace this with appropriate text');

    The following example shows how to set values in an MRVS. In this example, salaries are being managed through the Service Catalog. The client script searches all rows within the MRVS for the value entered in the Job title and then updates the matching entries within the MRVS with what is entered in the Salary field. The MRVS is named "variable_set_1" and contains the following fields within each row object: Employee name [employee_name], Job title [employee_job_title], and Salary [employee_salary]. In addition, the Catalog Item contains: Job title [job_title] and Salary [salary].

    function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
    return;
    }
    
    // Get the MRVS
    var multiRowVariableSet = JSON.parse(g_form.getValue('variable_set_1'));
    
    for (var i = 0; i < multiRowVariableSet.length; i++) {
    // Check if the entered job title matches the title in the current MRVS row
      if (multiRowVariableSet[i].employee_job_title == g_form.getValue("job_title")){
        // Update the value of a matching field with the new salary
        multiRowVariableSet[i].employee_salary = newValue;
      }
    }
    
    // Update the MRVS
    g_form.setValue('variable_set_1', JSON.stringify(multiRowVariableSet));
    }

    GlideForm - setValue(String fieldName, String value, String displayValue)

    Sets the value of a specified form field to the value of a specified display value in a reference record.

    To improve performance by preventing a round trip when setting the value for a reference field, use this method, not setValue(fieldName, value). When setting multiple reference values for a list collector field, pass arrays in the value and displayValue parameters.

    On fields set to strict read only, this method does nothing when used and a warning is logged in the browser's console. For more information, see Configuring read-only security options.

    注:
    The method setValue() can cause a stack overflow when used in an onchange client script. This is because every time the value is set, it will register as a change, which may re-trigger the OnChange client script. To prevent this, perform a check that will validate that the new value will be different from the old value. For example, before performing setValue(shortDesc, newValue.toUpperCase());, validate that the short description is not already uppercase. This will prevent the client script from applying the toUpperCase() more than once.
    表 : 147. Parameters
    Name Type Description
    fieldName String Name of the form field to update.
    value String or Array Sys_id of the reference record to use to update the field.

    If the specified field is a GlideList, this parameter can contain an array of sys_ids. In this case, the method performs a lookup of all records specified in the array and those values are used to update the contents of the specified field (related list).

    注:
    When defining a value in a choice list, be sure to use a number value rather than the label.
    displayValue String or Array Field within the specified reference record to use to update the specified field. For example, in the User [sys_user] table it might be userName.

    If the specified field is a GlideList, this parameter can contain an array of display value names.

    For additional information on display values, see Display value.

    表 : 148. Returns
    Type Description
    void

    This example shows passing the sys_id of the reference record that contains the userName field to use to update the assigned_to form field.

    g_form.setValue('assigned_to', userSysID, userName);

    This example shows passing an array of reference record sys_ids and an array of corresponding display value names to use to update the form fields in the GlideList glide-list_field_name.

    g_form.setValue('glide-list_field_name', sysIDArray, displayNameArray);

    GlideForm - setVariablesReadOnly(Boolean isReadOnly)

    Makes a Service Catalog variable editor read only.

    注:
    This method is only applicable to Service Catalog variable editors in the core UI. This method is not supported in the Service Catalog form.

    The method must be placed in the client script of the table in which the variable editor is added, such as Requested Item [sc_req_item], Incident [incident], and so on. To set variables to read only in other tables, use the setReadOnly() method.

    See also: Service Catalog variable editors

    表 : 149. Parameters
    Name Type Description
    isReadOnly Boolean Flag that determines whether the variable editor is read only.
    Valid values:
    • true: Sets the variable editor as read-only.
    • false: Sets the variable editor as editable.

    Default: false

    表 : 150. Returns
    Type Description
    void

    Adding the following line to a client script sets the variable editor to read only.

    g_form.setVariablesReadOnly(true);

    GlideForm - setVisible(String fieldName, Boolean display)

    Displays or hides the specified field.

    On desktop UI, the space is left blank when hidden. On Mobile or Service Portal UI, the space is filled in my other fields when hidden. This method can't hide mandatory fields with no value.

    Use UI Policy rather than this method whenever possible.

    表 : 151. Parameters
    Name Type Description
    fieldName String Name of the field to display or hide.
    display Boolean Flag that indicates whether to display the specified field.
    Valid values:
    • true: Display the field.
    • false: Hide the field.
    表 : 152. Returns
    Type Description
    void
    function onChange(control, oldValue, newValue, isLoading, isTemplate) {
       //If the page isn't loading
       if (!isLoading) {
          //If the new value isn't blank
          if(newValue != '') {
             g_form.setVisible('priority', false); 
          }
          else
             g_form.setVisible('priority', true); 
          }
       }

    GlideForm - showAnnotation(String name)
