How to prevent an ajax call when already it's been initiated?
<p>Suppose there is a form. When the form is being submitted I'm calling an ajax request to server. While it's being executing I don't want that ajax call to be triggered again.
Once I the ajax call is complete then only the ajax call can be trigger again.</p>

<p>How can I implement this? Here I want to use JQUERY library to implement this.</p>
