Hello Chandra,

1. With the help of UI Policy and UI Policy Action you can clear the value or set mandatory or Set visibility as well

2.Another option, you can use below scripts:

clearValue(String fieldName) :Removes any value(s) from the field.
setDisplay(String fieldName, Boolean display) :Displays or hides a field.
setMandatory(String fieldName, Boolean mandatory)

Makes the specified field mandatory.

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

g_form.setMandatory('field name', true);

g_form.setDisplay('field name', true);

g_form.clearValue('field name');

Please mark as Correct Answer and Helpful, if applicable.
Thanks!

Hi

You can use clear value as well as setValue.

https://developer.servicenow.com/app.do#!/api_doc?v=london&id=r_GlideFormClearValue_String

If it is a reference field you need to do something like this -

g_form.setValue("reference_field_name","");

For setting it mandatory you can use setMandatory function of g_form -

Hope this helps.

Hi

Try this script -

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
 if (isLoading || newValue === '') {
 return;
 }


g_form.setValue("ca_template","");//if it is a reference field
g_form.clearValue("ca_template");//if it is a reference field
g_form.setMandatory('ca_template', true);//set this field to mandatory

}
