jQuery.ajax troubles, can someone help?
I'm trying to fetch the html GET response from a webpage with this code
window.addEventListener('load', function () {start()} ,false);
function start(){
with(window){
/*Loading jQuery here */
jQuery.ajax({
url: 'http://api.jquery.com/jQuery.ajax/',
type: 'GET',
success: function(res) {
alert("Done!"); },
error: function (XMLHttpRequest, textStatus, errorThrown){
alert(XMLHttpRequest.status);
alert(XMLHttpRequest.responseText); }
});
};
}
but I had no luck, it gives me '0' at XMLHttpRequest.status, and 'undefined' to XMLHttpRequest.responseText.
Can someone help me get out of this?
It could be that your use of with is causing trouble. It's not allowed in strict mode.

It could also be that, unless you're calling this from jquery.com, that's a cross origin request. There's an article on dev.opera about this, but I'm not entirely sure how jQuery handles cross origin requests. From what I understand, if jQuery's server isn't set up to allow cross origin resource sharing, you won't be able to download jQuery via XHR from a user script. (You could use an extension though, as the background script can make cross origin requests.)

Shouldn't that result in an error in the error console?
Anyway, to expand on what I was saying, it can be ambiguous to what the with should apply precisely.

Maybe if you were using plain XHR, but jQuery could be swallowing the error.

Ah, good point.
