yahoo YUI ,太恶心

			var onCallback = {
				success : function(res){
					alert("-----");
				},
				failure :function(){alert("Date Error!");}
			};
		
			var formObject = document.getElementById('repository-form');
			YAHOO.util.Connect.setForm(formObject);
			var cObj = YAHOO.util.Connect.asyncRequest('POST', formObject.action, onCallback);

 YUI,的回调函数必须写在前面
