Description
This seems to be a bug introduced in jQuery 1.2.2, since it works in 1.2.1:
I'm making an AJAX call like: $.ajax({
dataType: "json", success: function() { ... }, error: function() { ... }, url: "http://localhost:8080/myurl"
});
Firefox responds with "Invalid Label". If I change the url to "/myurl", it works. In jQuery 1.2.1, both work.

By using POST instead of GET the problem is avoided.
Works:
// Do Ajax
$.ajax({
type: 'POST',
url: 'http://localhost/path/actions.ajax.php',
data: {test:'case'},
dataType: 'json',
success: function(result){
alert(result);
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert(errorThrown);
}
});
Fails:
// Do Ajax
$.ajax({
url: 'http://localhost/path/actions.ajax.php',
data: {test:'case'},
dataType: 'json',
success: function(result){
alert(result);
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert(errorThrown);
}
});

Ok, this should be fixed with [4476]. See the changeset for details. This change essentially returns the line to the way it was in 1.2.1 which was working.
Note: See

Here is use case that breaks in jquery-1.2.2 and Firefox Let's assume the form tag is generated dynamically and javascript is static and in separate file.
<html> <head> <script type="text/javascript" src="jquery-1.2.2.min.js"></script> <script type="text/javascript"> $(function() { var url = document.forms[0].action; //var url = '/notification/proxy.cfm/user/'; $.getJSON(url, function(result){ alert(result.rows.length); } ); }) </script> </head> <body> <form action="/notification/proxy.cfm/user/" type="GET"> </form> </body> </html>
