# GlideModal - Client

# GlideModal - Client {#ariaid-title1}

* Release version: Australia
* 
* Updated March 12, 2026
* 
* ![](https://www.servicenow.com/docs/portal-asset/ico-clock) 10 minutes to read

The GlideModal API provides methods for displaying a content overlay, known as a modal. Modals are interactive windows that appear above a page and close when a user takes an action. You can use a modal to display information, ask questions, or perform actions.

Use the GlideModal methods in scripts anywhere that you can use client-side JavaScript. These methods are most often called from a UI action with the Client check box selected.  
For modal options and compatibility in Configurable Workspace in the Next Experience UI, refer to the following:

* [g_modal (Next Experience) - Client](https://www.servicenow.com/docs/b4~LI4IrIPPkTKMUfoGDfg#g_modalClientAPINX "The g_modal API enables you to display a modal window to enhance application functionality.")
* [GlideModal (Next Experience) - Client](https://www.servicenow.com/docs/GdXpj0_V0JH383UsAL1ZPA#GModClientAPINX "The GlideModal API provides methods for displaying a content overlay, known as a modal. Modals are interactive windows that appear above a page and close when a user takes an action. You can use a modal to display information, ask questions, or perform actions.")
{#c_GlideModalV3API__ul_oyf_v1f_1gc}  
Figure 1. Example modal  
Modals can contain different types of content such as:

* Static text
* Dynamic text
* Forms
* Images
* Buttons  
Using this API you can:

* Get an existing modal.
* Create modal content from a UI page or from passed HTML.
* Set the title in the modal.
* Set the width of the modal.
* Get and set preferences.
* Switch modal views.  
To make a modal appear in the UI you must call one of the render methods:

* [GlideModal - render()](https://www.servicenow.com/docs/k4TWxtpCP~m4PzLxXNMPew#r_GMODV3-render "Renders the UI page specified when the API was instantiated in the modal. You must call this method after you define the modal for it to appear in the UI.")
* [GlideModal - renderWithContent(String html)](https://www.servicenow.com/docs/k4TWxtpCP~m4PzLxXNMPew#r_GMODV3-renderWithContent_S "Displays a modal with the specified string-based HTML content.")
{#c_GlideModalV3API__ul_n2g_g3d_kcc}  
The following code example shows how to create and render a modal using the UI page "UI_dialog_name".

    var dialog = new GlideModal("UI_dialog_name");

    //Set the dialog title
    dialog.setTitle('Show title');

    //Set the dialog width		      	
    dialog.setWidth(550);

    //Display the modal
    dialog.render();

This code example shows how to create and render a modal using the renderWithContent() method and HTML to define the content of the modal.

    function cancelDialog(){

      var dialog = new GlideModal('cancelTask');
      //Sets the dialog title
      dialog.setTitle('Cancel Task');
      //Set up valid custom HTML to display
      dialog.renderWithContent('<div style="padding:15px"><p>What action do you want to take?</p>
        <p><select name="cancellation" id="taskCancellation" class="form-control">
        <option value="cancelOnly" role="option">Cancel this task but keep the requested item open</option>
        <option value="cancelAll" role="option">Cancel this and all other tasks, closing the requested item</option>
        </select></p><div style="padding:5px;float:right"><button style="padding:5px;margin-right:10px" 
        onclick="window.changeTaskAction(this.innerHTML,jQuery(\'#taskCancellation\').val())" 
        class="btn btn-default">Abort</button><button style="padding:5px" class="btn btn-primary" 
        onclick="window.changeTaskAction(this.innerHTML,jQuery(\'#taskCancellation\').val())">Cancel Task</button></div></div>');

      //Use the windows object to ensure the code is accessible from the modal dialog
      window.changeTaskAction = function(thisButton, thisAction){

        //Close the GlideModal dialog window
        dialog.destroy();

        //Submit to the back-end
        if(thisButton=='Cancel Task'){
          if(thisAction=="cancelAll"){
            g_form.setValue('state',4);//Closed Incomplete -- will close the Requested Item and all other open tasks
          }else{
            g_form.setValue('state',7);//Closed Skipped -- will only close this task
          }
             //Regular ServiceNow form submission
             gsftSubmit(null, g_form.getFormElement(), 'cancel_sc_task');
          }
       };
       return false;//Prevents the form from submitting when the dialog first load
    }

Note:  
This is a fully-featured replacement for the GlideWindow and GlideDialogWindow APIs.

      //Sets the dialog title
      gmod.setTitle('Cancel Task');
      //Set up valid custom HTML to be displayed
      gmod.renderWithContent('<div style="padding:15px"><p>What action do you want to take?</p>
        <p><select name="cancellation" id="taskCancellation" class="form-control">
        <option value="cancelOnly" role="option">Cancel this task but keep the requested item open</option>
        <option value="cancelAll" role="option">Cancel this and all other tasks, closing the requested item</option>

        closeGlideModal();
      }, 100);
    }

## GlideModal - get(String id) {#ariaid-title4}

You can also specify either the `glide_modal_confirm` or `glide_modal_info` modals that are provided in the base system. Table: UI Page \[sys_ui_page\] |
[Table 4. Parameters]

{#r_GMODV3-get_S__table_vwy_xjz_3v} {#r_GMODV3-get_S__table_wwy_xjz_3v__entry__2}{#r_GMODV3-get_S__GMod-get-return-entry}

[Table 5. Returns]

{#r_GMODV3-get_S__table_wwy_xjz_3v}

    // If the modal was initially created like this:

    var dialog = new GlideModal("glide_modal_confirm"); 
    dialog.render();

    // Code using the modal
    ...

    // Now use the get() and destroy() methods to close the modal
    var glideModal = new GlideModal().get("glide_modal_confirm");
    glideModal.destroy();

    // You can also code it like this:
    // GlideModal.prototype.get('glide_modal_confirm').destroy();

## GlideModal - getPreference(String name) {#ariaid-title5}

Returns the value of the specified preference (property).
Invoking actions that create the modal typically also create the necessary preferences for the modal using the [GlideModal - setPreference(String name, String value)](https://www.servicenow.com/docs/k4TWxtpCP~m4PzLxXNMPew#r_GMODV3-setPreference_S_S "Sets the specified field on the current form to the specified value.") method. The UI page client script can then consume these
preferences using this method.

    //Sets the value of the preference table
    dialog.setPreference('table', 'incident');

    //Gets the value of the preference table
    var title = dialog.getPreference('table');

## GlideModal - render() {#ariaid-title6}

Renders the UI page specified when the API was instantiated in the modal. You must call this method after you define the modal for it to appear in the UI.
Call this method when you use a UI page to generate the content in your modal. If you want to display HTML within a modal, call [GlideModal - renderWithContent(String html)](https://www.servicenow.com/docs/k4TWxtpCP~m4PzLxXNMPew#r_GMODV3-renderWithContent_S "Displays a modal with the specified string-based HTML content.") to render the modal.
