I'm having a problem with, guess what, IE8. The following code, simplified for clarity, does not work at all:
alert('before get');
$.get(getActivityURL('ActionName',{
ts: new Date().getTime(), ...other params...}),
{cache:false;},
function (xml) {
alert("in get callback");
},'xml'); // End $.get()
alert('in after get');
The getActivityUrl() outputs a valid URL with request parameters.
This works correctly in FF and Chrome. However, in IE8, this doesn't even get into the $.get() callback. I get the "before" and "after" alerts, but not the "in" alert and indeed, nothing happens and the request is NOT sent. I don't really know what to think here.
The response headers are "Content-Type:application/xml; charset:iso-8859-1" as confirmed in FF.
EDIT: $.post() doesn't work, either.
