实现功能：在一个容器里点击一个链接，在另外一个容器中显示这个链接所指向页面的内容。
<html>
<head>
    <script src="./dojo/dojo.js">
    </script>
    <script>
        dojo.require("dojo.widget.ContentPane");
        var links = null, display = null;
        dojo.addOnLoad(init);
        function init(){
            links = dojo.widget.byId("links");
            display = dojo.widget.byId("display");

            // listen to links domNode for onclick event
            // lowercased on all DOM events as opposed to widget events

            //"onclick",必须是小写的
            dojo.event.connect(links.domNode, "onclick", 'relayClicks');

        }
        // finds out if this is a link event
        function relayClicks(evt){
            var node = evt.target;//取得事件源
            if(node.nodeName.toLowerCase() == "a"){
                // it is a link, prevent the browser from unloading the page
                evt.preventDefault();
                // change page in display pane
                display.setUrl(node.href);
            }
        }
    </script>
</head>
<body>
    <h1>Example on how to easily relay <a href="someurl.html" target="display"> clicks</h1>
    <div dojoType="ContentPane"
        widgetId="links"
        style="float:left ; width: 200px; height: 400px; border: 1px solid red;"
    >
        <a href="link1.html">Link 1</a><br/>
        <a href="link2.html">Link 2</a><br/>
        <a href="link3.html">Link 3</a><br/>
    </div>
    <div dojoType="ContentPane"
        widgetId="display" name="display" id ="display"
        style="width: 600px; height: 400px; border: 1px solid blue;"
    ></div>
</body>
