.ajax load remote page content to javascript var

I want to get a short string hosted on a server where I do not have access to the data as XML, JSON, etc. I am trying to开发者_如何学编程 use either .load or .ajax to do this. I want to be able to parse the data into a javascipt array. The entire contents of the remote page is text and I am happy to take all of it and remove what I do not need via a small javascript. I have tried:

<script>
$(document).ready(function(){
$("button").click(function(){
  $.ajax({url:"http://url:8888/data", success:function(result){
    $("div").html(result);
  }});
});});
</script>

I have two questions. 1- why does this not work? 2- What would be the best way to store the string in a javascript var?

I am sure JQuery is working correctly.

The answer would be to long to post here (really). But look those up:

• Same Origin Policy
• Padded JSON

If you have no control over the remote site, you have lost - you will not get any data from it by Ajax (which is actually a feature, not a limitation of the technology). One way of circumventing the protection would be to build a proxy that just mirrors the remote service you need to reach and makes it available in the same domain that your main HTML came from.
