[jQuery] Re: getJSON and (this)

[Karl Swedberg]

You're within the scope of another function.

If you want to keep a reference to the clicked link, you could do  
something like this:


$j("a.complete").click(function () {
       var $aComplete = $j(this); // <-- hold onto to $j(this)
       $j.getJSON("https://foobar?my="; + $j(this).attr("title"),
       function(data){
               if (data.status == "Completed") {
                        //Woohoo, it worked!
                        alert("Woohoo!");

                        //Now lets change the div style!
			$aComplete.parent().removeClass('foobar'); // <-- reference the  
clicked link ( $j(this) )

                        //Hey, that didn't do anything!

                        //This worked above, lets test and see if it contains a 
value.
                       alert($aComplete.attr("title"));  // <--  
reference the clicked link ( $j(this) )

                        //undefined? =(
               }
       });

Doesn't look like you're doing anything with the data that you're  
retrieving, though. Was that left out for example brevity?

Hi. Can anyone tell me while once I get inside the success function
$j(this) is no longer defined?

Thanks! :)

$j("a.complete").click(function () {
       $j.getJSON("https://foobar?my="; + $j(this).attr("title"),
       function(data){
               if (data.status == "Completed") {
                        //Woohoo, it worked!
                        alert("Woohoo!");

                        //Now lets change the div style!
                        $j(this).parent().removeClass('foobar');

                        //Hey, that didn't do anything!

                        //This worked above, lets test and see if it contains a 
value.
                       alert($j(this).attr("title"));

                        //undefined? =(
               }
       });
