How to trigger OnClick and OnClientClick events simultaneously in ASP.NET when using jQuery?

Question

I am trying to display a message bar during postback. I am using a jQuery script I found online here . Everything works great separately, but when the jQuery is added to the page my server side event is never called.

Here is my button code:

<asp:Button ID="btnGetReport" CssClass="float-left" runat="server" 
Text="<%$ Glossary:GetReport %>" OnClick="btnGetReport_Click" />

This is the inline script:

<script type="text/javascript">
$(document).ready(function () {
    $('#<%=btnGetReport.ClientID%>').click(function (event) {
        event.preventDefault();
        $('#message_bar').displayMessage({
            position: 'fixed',
            skin: 'modern',
            message: 'We are fetching your report. Please wait...',
        });
    });
});
</script>

This is the related external .js file:

(function( $ ){

$.fn.displayMessage = function(options) {

    // Default configuration properties.
     var defaults = {
              message       : 'Error message',
              speed         : 'fast',
              position      : 'fixed', // relative, absolute, fixed
              autohide      : true
     }

    var options = $.extend( defaults, options );
    $(this).slideUp('fast');
    $(this).removeClass().empty();
    return this.each(function() {

      var sticky = (options.sticky == false) ? 'relative' : 'absolute';
      $(this).addClass('messagebar-skin-'+options.skin+'_bar').css('position',options.position).css('background-color',options.background);
      $(this).append('<div class="messagebar-skin-'+options.skin+'_inner"><span class="messagebar-skin-'+options.skin+'_text"></span></div>').css('color',options.color);
      $(this).find('span').html(options.message);

      $(this).slideDown(options.speed ,function(){

         var parent = ($(this).attr('id')) ? "#"+$(this).attr('id') : "."+$(this).attr('class');
         var close_button = ($(this).find('a').attr('id')) ? "#"+$(this).find('a').attr('id') : "."+$(this).find('a').attr('class');

         if(options.autohide == true)
         {
            $(this).delay(2400).fadeOut('slow');
         }

         $(parent+">div>"+close_button).bind("click", function (event) {
            event.preventDefault();
            $(parent+">div>"+close_button).animate({"opacity": "hide"}, function(){
                $(parent+">div>span").fadeOut("slow").html("");
                $(parent+">div>"+close_button).parent().parent().slideUp(options.speed);
            });
         });

  });

});

};
})( jQuery );

I have also tried calling the function with the OnClientClick property, but neither one seems to work. I looked at other examples where people were having issues with this but none of them seemed to help either.

Any thoughts would be greatly appreciated!

Answer 1

Have you tried something simple like:

OnClientClick="return YourJavaScriptFunction();"

<asp:Button ID="btnGetReport" CssClass="float-left" runat="server" 
    Text="<%$ Glossary:GetReport %>" OnClick="btnGetReport_Click" 
    OnClientClick="return YourJavaScriptFunction();" />

and in your JavaScript function return true at the end

function YourJavaScriptFunction () {
    // your cool stuff
    return true;
}

Edit 1

This line:

OnClientClick="return YourJavaScriptFunction();"

It's the equivalent to:

$('#<%=btnGetReport.ClientID%>').click(function () {

Your script would look like:

<script type="text/javascript">

function YourJavaScriptFunction (){
        $('#message_bar').displayMessage({
            position: 'fixed',
            skin: 'modern',
            message: 'We are fetching your report. Please wait...'
        });    

        // this will prevent the postback, equivalent to: event.preventDefault();
        return false;
}

</script>

Try this:

   <script type="text/javascript">
    $(document).ready(function () {
        $('#<%=btnGetReport.ClientID%>').click(function (event) {
            event.preventDefault();
            $('#message_bar').displayMessage({
                position: 'fixed',
                skin: 'modern',
                message: 'We are fetching your report. Please wait...',
            });
         __doPostBack("btnGetReport", "");
        });
    });
    </script>

if using Master Page then try this:

 __doPostBack("ctl00$MainContent$btnGetReport", "");
