ServiceNow: modifying field hint

Note: this is an older post, DOM manipulation is not recommended in ServiceNow



  • use annotation via configure form layout > * annotations
  • use g_form.showFieldMsg > use 4th boolean parameter and set to false to stop the form auto-scrolling to the field
  • use g_form.addDecoration

here's a rather clunky way of editing the change_request.test_plan hint:

var el = gel("label.change_request.test_plan");
//var el = gel("status.change_request.test_plan");
alert (el.innerHTML);

document.getElementById('status.change_request.test_plan').setAttribute('title', 'BLAHBLAH');
document.getElementById('status.change_request.test_plan').setAttribute('aria-label', 'BLAHBLAH');

 var elements = el.getElementsByTagName('span');
alert('LEN: ' + elements.length);
for(var i = 0; i < elements.length; i ++) {
        if(elements[i].className === 'label-text') {
elements[i].setAttribute('title', 'BLAHBLAH');

GlideRecord setValue

setValue(String name, Object value) Sets the specified field to the specified value. Normally a script would do a direct assignment, for example,  gr.category = value . However, if in a script the element name is a variable, then  gr.setValue(elementName, value)  can be used. When setting a value, ensure the data type of the field matches the data type of the value you enter. This method cannot be used on journal fields. If the value parameter is null, the record is not updated, and an error is not thrown!/api_doc?v=madrid&id=r_GlideRecord-setValue_String_Object
