Hello Sir
I want to know - is there any way or approach to disable client side form's "Submit" button.
Please give code also.

For all submit buttons, via JQuery, it'd be:
$('input[type=submit]').click(function() { this.disabled = true; });
Or it might be more useful to do so on form submission:
$('form').submit(function() {
$('input[type=submit]', this).attr("disabled","disabled");
});
But I think we could give a better answer to your question if we knew a bit more about the context.
If you are facing any programming issue, such as compilation errors or not able to find the code you are looking for.
