According to Same Origin Policy, SOP shouldn't apply to file:// protocol, but why my code does not work? I am running this testing page from my local system and I have abc.txt in the same directory as the html page. If I change URL to http://www.google.com/, it does not work too. I don't understand why, could anyone explain?
<!doctype html>
<html lang="us">
<head>
<meta charset="utf-8">
<title>jQuery UI Example Page</title>
<link href="css/sunny/jquery-ui-1.10.2.custom.css" rel="stylesheet">
<script src="js/jquery-1.9.1.js"></script>
<script src="js/jquery-ui-1.10.2.custom.js"></script>
<script>
$.support.cors = true;
$(function(){
$(".btn1").button().click(function(){
$.ajax({
url: "abc.txt"
}).done(function(result) {
alert("done");
$(".content").html(result);
}).fail(function() {
alert("error");
});
});
});
</script>
</head>
<body>
<button class="btn1">Click me!</button>
<div class="content"></div>
</body>
</html>
Edited: The console printed as below:
XMLHttpRequest cannot load file:///C:/Users/yc/Desktop/jquery%20ajax%20testing/jquery-ui-1.10.2.custom/jquery-ui-1.10.2.custom/abc.txt. Origin null is not allowed by Access-Control-Allow-Origin.
*It does not work for Firefox, IE too.
