Client Script: Pop up confirmation on Field Change

[Scott29]

I currently have a very basic client script that confirms a field change (Script Below). Is there a way if they select cancel on the prompt, it reverts the field value to what it was before?

function onSubmit() {

    var legal = g_form.getValue('legal_review');

    if (legal =='No'){

      return;

  }

  var answer = confirm("Are you sure you want to set a Legal Review?");

    if (legal =='Yes'){

      // User clicked Cancel, prevent the form from being saved

      return false;

  }

}

Hi @Scott29, 

You can use hidden variable and copy the previous value and use that same in case of "Cancel".

the following script may get you the behavior you want.

function onSubmit() {
   //Type appropriate comment here, and begin script below
    var legal = g_form.getValue('u_legal_review');
	alert('u_legal_review = ' + legal);
	if (legal =='No'){
    	return;
  	}
	return confirm(getMessage('Are you sure you want to set a Legal Review?'));
	//  var answer = confirm("Are you sure you want to set a Legal Review?");
	//  if (legal =='Yes') {
      		// User clicked Cancel, prevent the form from being saved
	//      return false;
	//  }
}
