Here:

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>.

function onLoad() {

g_form.getControl('sys_display.rm_defect.assignment_group').style.width = '350px';

}

What exactly are you trying to achieve in the first place?

If you go to Client Scripts in the instance and search for Script contains getControl you'll find many examples:

Hi Manohar,

This could be due to following issues :

1. 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>.

2. ServiceNow KB:   The g_form.getControl method does not work after ordering   (KB0547171)

3. getControl not working

4. g_form.getControl() not working in Service Portal in Catalog Client Script
