fetch all fields in a g_form

[georgechen]

Hi folks again,

Is there a way to loop through available fields in a g_form, instead of hard-coding each field name.     g_form has a method getControl which expects a field name, the control can be fetched, but you have to specify the fieldname, I wonder if the fields can be dynamically lopped through the g_form fields (or variable something like this)

Any advice would be appreciated.

Thanks,

GlideForm (g form) - ServiceNow Wiki

10.2 getControl

HTMLElement getControl(fieldName)

Returns the HTML element for the specified field. Compound fields may contain several HTML elements.

Generally not necessary as there are built-in methods that use the fields on the form.

Parameters:

fieldName - specifies the name of the field.

Returns:

HTMLElement - the specified HTML element(s).

Note: If the field is of type reference and the control is a choice list, getControl() may not return control as expected. In this case, use sys_select.<table name>.<field name>.

I previously tried to do this and had some success using the 'nameMap' object. Here are a couple of snippets that may be of help. The second one was used to loop through all fields and toggle the help annotation on:

for (var index = 0; index < g_form.nameMap.length; index++) {   
     jslog("Name Map # " + index + ": " + g_form.nameMap[index].prettyName);   
}


for (var index = 0; index < g_form.nameMap.length; index++) {   
     jslog("Name Map # " + index + ": " + g_form.nameMap[index].prettyName);   
var helptext = g_form.getControl(g_form.nameMap[index].prettyName);
toggleHelp(helptext.id);
}

Not sure if that is useful.

Cheers,

Tim

Hi George,

g_form.nameMap works only for variables. For fields, you can use g_form.elements, as what @Madhu Umapathy said.

I use something like this:

for(var x = 0; x < g_form.elements.length; x++){

g_form.setDisplay(g_form.elements[x].fieldName, true);

}

I tried below script and it makes the variables along with fields on catalog task readonly except for the variables which are reference/checkbox. 

function onLoad() {
if(g_form.getValue('active') == "false"){
for(var x = 0; x < g_form.elements.length; x++)
{
g_form.setReadOnly(g_form.elements[x].fieldName, true);
}
}
}

Is there a way i can make only fields read only not the variables on catalog task? (Instance is Madrid)

This was my solution, using only documented commands...

var dict = new GlideRecord("sys_dictionary");
dict.addQuery("name", g_form.getTableName());
dict.addQuery("internal_type", "!=", "collection");
dict.query();
while (dict.next()) {
  var elem = dict.getValue("element");
  if (g_form.getElement(elem)) {
// show only fields that exist on this form...
    g_form.addInfoMessage(elem);
  }
}

The g_form.addInfoMessage(elem); can be changed to whatever!

writing glide record in client script is not good practice. 

instead of writing the glide record part in client script , use glide ajax here .

create one client callable script include and use the glide record part there and then use glide ajax  inside the client script to get the all details in g_form.addInfoMessage()
