How To Define Url For Custom Jquery Ajax In Yii

Yii 1.1 General Discussion

I have been writing some ajax call in an external javascript file, finding some difficulties to set the URL. When I check in the console that URL does not reach at controller. I wrote url in ajax as:




    	$.ajax({

		type: 'POST',

		url: 'project/projectDelete',

		data: project_id,

		success: function(msg){

			if(msg == 'done') {

				$('.loaderContainer').hide();

				$('#'+projectid).parent().parent().remove();

			}


		}

	}); //END $.ajax

I got in console the URL request as http://localhost/example/index.php/cp/project/project/projectDelete. But it should be http://localhost/decksgo_new/index.php/cp/project/projectDelete. Is there any correct way to define URL in ajax in Yii external javascript.
