jQuery.get not receiving data
I have the following html + jquery:
<body>
<head>
<script type="text/j开发者_StackOverflow中文版avascript" src="jquery.js"></script>
<script>
$(window).load(function() {
$('#test').bind('click', function() {
$.get("http://localhost:3000/promotions.xml", function(data){
alert("Data Loaded: " + data);
});
});
});
</script>
</head>
<input id="test" type="button" value="Testando">
</body>
The problem is that the data parameter is empty, even though when I test the url on the browser I see a xml file with some data into it. I tried switching to HTML and json and it didn't work either. The server reports that everything is fine:
Started GET "/promotions.xml" for 127.0.0.1 at Thu Feb 10 16:02:33 -0200 2011
Processing by PromotionsController#index as XML
←[1m←[35mPromotion Load (1.0ms)←[0m SELECT "promotions".* FROM "promotions"
Completed 200 OK in 41ms (Views: 31.0ms | ActiveRecord: 1.0ms)
So I guess it is something in javascript/jQuery that I'm missing. I'm using jquery 1.4.4. What's wrong?
I'd guess that it is a result of the Same Origin Policy, which requires that AJAX requests be made to the same location as the page's origin.
If the page isn't hosted from localhost:3000, that would violate the policy.
If you're testing with Chrome, you should be able to disable the security policy by launching it from a terminal application with:
--disable-web-security
加载中,请稍侯......
