I want to write JQuery which will find whether Class="Mandatory" exists on the page and if any element is having this class then only perform certain action.
Thanks
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();
});
}
EDIT If 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
}
});
