<html>
<head>
    <meta charset="utf-8">
    <style type="text/css">
        div {
            background: magenta;
            width: 500px;
            height: 300px
        }
    </style>
    <script src="js/jquery-1.8.3.js"></script>
    <script>
        var z = jQuery.noConflict();
        jQuery(function(){
            alert("hello");
        })
        z(function () {
            alert("world");
        })
    </script>
</head>
<body>
    <div></div>
</body>
</html>

代码如上图，用了noConflict()方法，但是还是可以用jQuery来调用方法，用z调用也可以，不是应该不能用jQuery调用了吗？

你应该这么用：

$.noConflict(true)

If necessary, you can free up the jQuery name as well by passing true as an argument to the method. This is rarely necessary, and if you must do this (for example, if you need to use multiple versions of the jQuery library on the same page), you need to consider that most plug-ins rely on the presence of the jQuery variable and may not operate correctly in this situation.
