JQuery 1.4.2 JSON format that breaks down what was used to work in 1.3.2

Question

I just upgraded jQuery from 1.3.2 to 1.4.2, and I think this gives me some problems. I have a function $.post() , which calls the controller method and passes on some data, which I format like this:

 $.post(url, { arrayParam: myArray, param2: false }, someCallback, 'html'); 

In Firebug, POST says the parameters in 1.3.2 are as follows:

 arrayParam: 100 arrayParam: 101 (etc..) 

But for 1.4.2 they look like this:

 arrayParam[]: 100 

This crashes my controller expecting a List<Int32> for arrayParam (and causes some JSON problems around the codebase). Is there any way around this without returning to 1.3.2 or reprogramming all my controllers?

thanks

As with jQuery 1.4, the $ .param () method serializes deep objects recursively to accommodate modern scripting languages ​​and frameworks such as PHP and Ruby on Rails. You can disable this functionality globally by setting jQuery.ajaxSettings.traditional = true; .

jQuery ajax methods use $ .param () for transferred data.

See jquery param for details.

Here is your fix:

 jQuery.ajaxSettings.traditional = true;
