jquery functions not working within an ajax loaded jquery tab


I'm having trouble getting jquery functions (datepicker and dialog) to work within an jquery ajax loaded tab.

I keep getting a "datepicker is not a function" or "dialog is not a function" when I click the respective tab. I've done a lot of searching online for this problem and there are similar problems, but I couldn't find a solution that works for me.

I do understand that with such an error, the problem is likely due the system not recognizing the script. So, on a higher level I'm not really understanding how the ajax loaded tab deals with scrips in relation to the master script.

Hopefully my code can help illustrate my error.

add: function() { 
    var form_data = $('form').serialize();
    $.ajax({
        type: "POST",
        url: "../manager/add_game.php",
        data: form_data, // Data that I'm sending
        error: function() {
            $('#status').text('Update failed. Try again.').slideDown('slow');
        },
        success: function() {
            $('#status').text('Update successful!').slideDown('slow');
        },
        complete: function() {
            setTimeout(function() {
                $('#status').slideUp('slow');
                }, 2000);
        },
        cache: false
    });
  }
}

$(document).ready(function() {
// Load game dialog
GAME.loadDialog();
});

Thanks for any help.

EDIT: I should note that the view_sch.php page works just fine when you view it in it's own browser window. The issue arises when viewing the page through the ajax loaded jquery tab.


Solution

  • I think I figured it out (with help of my friend too). I first removed the redundant external script calls in the view_sch page since header.html already took care of this. Next, I utilized the functions within the jquery tab, in particular the "load" event to create a callback situation. Ironically, it still wasn't working if you select the tab more than once until I added an if conditional to the load block. Hopefully the code below helps others out there.

    schedule.js

    var GAME = {
     loadDialog: function() {
        $("#date").datepicker();
        $( "#AddGameForm" ).dialog({
            autoOpen: false,
            height: 400,
            width: 400,
            modal: true
            }
        });     
      }
    } 
    $(document).ready(function()
    {
      // jQuery UI Tabs
      $('#tabmenu').tabs({
        ajaxOptions: {
            error: function( xhr, status, index, anchor ) {
                $(anchor.hash).html(
                    "Couldn't load this tab. We'll try to fix this as soon as possible. "
                );              
            }
        },
        load: function ( event, ui ) {
            if (ui.index == 2) {
                // Load game dialog
                GAME.loadDialog();
    
                $( "#add-game" ).on("click", function() {
                    $( "#AddGameForm" ).dialog( "open" ); 
                }); 
            }
        }
    });
