.post a .post response

in Using jQuery • 12 years ago

Hey everyone. I am pretty new to javascript and jquery and am looking for some help with the below code. My problem seems to be on line 8 (the second .post). My logs show that I am posting name as XMLHttpRespose. However, if I alert(name), the correct value is alerted.

Could someone help me to 1, understand WHY this doesn't work and 2, get it working correctly?

Thanks,

    function load_tabs() { 
     $.post("skins/new/includes/updateGroups.php?action=select", function(data) { 
      saved_tabs = data.split(","); 
      saved_tabs.pop(); 
      var x = saved_tabs.length; 
      for (var i=0;i<x;i++){ 
       var name = saved_tabs[i]; 
       var mids = $.post("skins/new/includes/updateMonitors?action=select&groupName=", name); // name Posts as XMLHttpResponse 
       $("#tabs").tabs('add', 'skins/new/views/monitors.php?mids='+mids, name); 
      } 
     }); 
    };

First, you're passing the name variable as a second parameter to $.post, which it treats as a data parameter. That line should probably look like this:

$.post("skins/new/includes/updateMonitors?action=select&groupName=" + name);

Second, you're setting the variable mids to the return of $.post, which is going to be the XMLHttpResponse object, which I don't think you want to be using in the tabs method they way you are on the next line.

Third, since it looks like you need the mids variable for that tabs function, the tabs function should be placed in a callback (third parameter to $.post) since the $.post function is asynchronous, meaning JavaScript execution will continue without waiting for it to complete.
