Description

If set default data via ajaxSetup()

For example

$.ajaxSetup({
 data : {'kid' : 'mike'}
})

And then use load('url',callback) , whith callback, data do not send to the server.

If use load('url') - All works correctly.

Same bug in get function....

In both functions, if second argument is a callback function, jQuery set data param to NULL value, and then it value rewrite default ajaxSettings.data in extend() function. Correctly use UNDEFINED value, because in extend() fucntion use hard type hinting

...

} else if ( copy !== undefined ) {
 target[ name ] = copy;
}

....

Actually both for version 1.5, and for version 1.4

Thanks for taking the time to contribute to the jQuery project by writing a bug report.

test case

It seems like most of the ajax shorthand functions are affected by this since 1.4 . As the reporter pointed out this happens because the utility functions set data to null when the second parameter is a function.

Affected functions: .get/.post/.load (.getJSON / .getScript too because they use .get internally)

Offending lines are https://github.com/jquery/jquery/blob/1.5/src/ajax.js#L232 and https://github.com/jquery/jquery/blob/1.5/src/ajax.js#L140

Fixes #8277. Sets data to undefined rather than null when it is not provided in ajax helpers so that it won't revent data set in ajaxSettings from being used. Unit test added.
