What is the use of control parameter in onChange in Client script

Hi Nagaraj,

I don't think control parameter is an OOTB field. Is this a custom field on your instance? A screenshot will be helpful.

Hi,

onChange() — runs when a particular field value changes on the form. The onChange() client script must specify these parameters.

• control: the DHTML widget whose value changed.
• oldValue: the value the widget had when the record was loaded.
• newValue: the value the widget has after the change.
• isLoading: identifies whether the change occurs as part of a form load.
• isTemplate: identifies whether the change occurs as part of a template load.

Hi, Control parameters are generally used for If we wants to change the dynamically field size, length etc in ui page . So we will use control parameter inside client script in onChange type. Please mark correct/ helpful if helpful for you . Thanks
