The value might require some calculation, something that will be provided later, like user input. A variable declared without a value will have the value undefined Using variable is useful in many ways. You might have a thousand lines of code that may include the variable x. When you change the value of x one time, it will automati...

In this post I'm going to demonstrate how to open a pop-up from using Nintex forms Implementation So, simply follow the steps mentioned below. Crate a new Custom JavaScript button. Go to Control Settings of button and add the following  On the Form Settings page add the following JS code on the "Custom JavaScript" section  function redirectToRFIForm(){ var options = { title: "Your Title", url: 'http://mysite/sites/page.aspx', dialogReturnValueCallback:Function.createDelegate(null, portal_modalDialogClosedCallback)}; SP.UI.ModalDialog.showModalDialog(options); }   ----------- Happy Coding -----------
