How to find particular class exists on a page using JQuery
Just check how many elements you hit, when you search for it with jQuery
if ($(".Mandatory").length > 0) { // Do stuff with $(".Mandatory") $(".Mandatory").each(function() { // "this" points to current item in looping through all elements with // class="Mandatory" $(this).doSomejQueryWithElement(); }); }EDITIf you wanna do that check for your submit button click, just do that check after the click:
$("input[type='submit']").click(function() { if ($(".Mandatory").length > 0) { // Do some code here }});
If you want to only do the action once, you could use:
if ($('.Mandatory').length > 0) { //do your thing}Otherwise if you want to do it for each Mandatory element:
$('.Mandatory').each(function(){ //do your thing});
The best way to do this is search class within the body tag.
$('body').find('.Mandatory').length;
