How to disable Buttons inside or outside Update Panel using jQuery

Hi Saurav,

Replace your code with below code

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script type="text/javascript">
    $(function () {
        $('input[type=submit]').click(function () {
            DisableButtons();
            return false;
        });
        var prm = Sys.WebForms.PageRequestManager.getInstance();
        if (prm != null) {
            prm.add_endRequest(function (sender, e) {
                if (sender._postBackSettings.panelsToUpdate != null) {
                    DisableButtons();
                }
            });
        };
    });
    function DisableButtons() {
        var inputs = document.getElementsByTagName("INPUT");
        for (var i in inputs) {
            if (inputs[i].type == "button" || inputs[i].type == "submit") {
                inputs[i].disabled = true;
            }
        }            
    }
    function EnableButtons() {
        var inputs = document.getElementsByTagName("INPUT");
        for (var i in inputs) {
            if (inputs[i].type == "button" || inputs[i].type == "submit") {
                inputs[i].disabled = false;
            }
        }          
    }
    </script>

Hope this works for you
