代码如下：

<html xmlns:v="urn:schemas-microsoft-com:vml">

        v\:* { behavior: url(#default#VML); }
    </style>
    <script type="text/javascript">
        // Your JavaScript code will go here.

        //Flag to stop rectangle from spinning.
        var spin;
        //Flag to first call makeRect function
        var first = true;
        // Make rectangle.
        function makeRect() {
            //if not first call, return.
            if(first == false)
                return;
            first = false;

            // Create element in memory.
            var r = document.createElement("v:rect");

            // Define width, height, color, and unique ID.
            r.style.width = 100;
            r.style.height = 100;
            r.fillcolor = "purple";
            r.id = "myRect";

            // Attach rectangle to the document at the the specified Div.
            var anchorDiv = document.getElementById(‘anchorDiv‘);
            anchorDiv.appendChild(r);
        }

        // Set up the rotation.
        function rotateRect() {
            // Call spinRect function every 10 milliseconds.
            // The spin variable allows us to clear the call to setInterval.
            spin = setInterval("spinRect()", 10);
        }

        // Spin the rectangle by specified increment every time function called.
        function spinRect() {
            // Increment rectangle rotation by 1 degrees.
            var myRect = document.getElementById(‘myRect‘);
