Do you Notice, When ServiceNow validate onSubmit client scripts apart from form submission?

[siva krishna M2]

1)ServiceNow will validate onSubmit client scripts to go to server side scripting in UI Action calling through gsftSubmit(null, g_form.getFormElement, 'Action name');

2) ServiceNow will validate onSubmit client script to go to list view history of the record through context menu => History => List.
