Client-side Glide API

The client-side Glide API exposes many different methods that can be used to customize the UI, access user sessions, and perform AJAX. Let us quickly go through the different client-side classes available in ServiceNow. We will be using these APIs in the upcoming chapters.

GlideForm

The GlideForm JavaScript class consists of methods that can be used to customize forms and modify form data. There is no need to explicitly create an object of the GlideForm class. Instead, the g_form variable is a global object and is available and accessible from all client-side scripts.

The following are some examples of GlideForm:

• The void setReadOnly method of the GlideForm object can be used to make a form field read only. It accepts two parameters - fieldname and the boolean read only property:

        g_form.setReadOnly("fieldName",true) 

• The void setValue method of the GlideForm object can be used to change the value of a Form field:

        g_form.setValue(fieldname, value)
