you use this the same as you would $.post or $.get headers are passed to the callback. This does not make use of promises or deferred as it predates them by quite a lot.

Hi,
I like your plug-in but missed the “status” header from the Response. Doing some debugging in Firefox, I found that you can actually access the “Status” response from a webserver in the XMLHttpRequest object in javascript. So I have created “a new version” of your plug-in which adds status and two other response headers to the “header” array returned to the callback function. It is the “multipart” and “withCredentials” headers.

Also I have created a new method “exists(url, callback)” which will return a true|false value to the callback function. The url could be for instance a local MP3 file.

You can find my “new sub version” here: http://dl.dropbox.com/u/3260327/jQuery.head.js

Thanks.

Bug in code posted at: http://plugins.jquery.com/files/jquery.ajax_head.js.txt

Line “for (var key=0;key<=l;key++) {"

should be "for (var key=0;key < l;key++) {"

Yay for 0 indexes.

I had to change

for (var key=0;key<=l;key++) {

for (var key=0;key

to get this to work. Which makes sense now I think about it…

I would note that in the source, you may wish to change your for loop from a “for…in” to a simple for loop.

When I use the current code, it comes back with an undefined error for split because one of the keys points to an exists() function. (which may be being defined against the Array Object by one of my libraries). Being a function, doesn’t have a split() function.

Alternatively, you could test to make sure that what you are working against is a string. Either way will help to increase robustness.

Was this made into a downloadable/recyclable plugin yet? I can’t find it in the jQuery plugin repository. It would be great to see it there.
