[jQuery] Re: Synchronous JSONP
What about using the success callback of the JSONP call to initiate the
location.href? Something like:
$('a').click(function() {
var href = $(this).attr('href');
$.ajax({
url: 'http://example.com/jsonpmethod?callback=?',
dataType: 'jsonp',
success: function(data) {
// do whatever with json encoded data
location.href = href;
}
});
return false;
});

Here is the use situation. We are using JSONP to send activity on pages
to avoid cross-site scripting problems. One of those activities is clicking
on a link.
The problem is that the JSONP is asynchronous so that when the link is
clicked, the page unloads before the JSONP has a chance to do it's thing.
What is the best way of allowing the JSONP to do it's thing and pause the
unload of the page long enough for it to work?

Glen,
I have never done it, but I say a while back that you can use the
jQuery.extend method to overwrite a default method. I will see if I can
dig that up, but that may point you in the right direction in the mean time.

This sometimes causes a problem when we are sending a call about a

Changing it to be optional (async or synchronous) helps fix that
problem.
Code we used inside jQuery (with a param call to .ajax)
/* If the request is not async, we need to wait for the script to l oad
before returning. */
else if (!s.async) {
var done = false;
// Attach handlers for all browsers
script.onload = script.onreadystatechange = function(){
if ( !done (!this.readyState ||
this.readyState == loaded || this.readyState == complete)
) {
}
};
}
QUESTION: Putting this directly into our copy of jQuery is probably a
bad idea. *How can this be turned into a plugin?*
Thanks much,
Glen
