Question

为什么这段代码会导致内存泄漏？

    <html>
    <body>
    <script type="text/javascript">
    document.write("Program to illustrate memory leak via closure");
    window.onload=function outerFunction(){
        var obj = document.getElementById("element");
        obj.onclick=function innerFunction(){
        alert("Hi! I will leak");
        };
        obj.bigString=new Array(1000).join(new Array(2000).join("XXXXX"));
        // This is used to make the leak significant
    };
    </script>
    <button id="element">Click Me</button>
    </body>
    </html>
