您好我正在尝试在 dojo 中使用 CheckedMultiSelect ...当我按下按钮时，CheckedMultiSelect 中的所有选中项目都应显示在文本框中..请编辑下面的代码...我尝试使用警报框它不起作用

<html>
<link rel="stylesheet" href="dijit/themes/claro/claro.css">
<script>dojoConfig = {parseOnLoad: true}</script>
<script src="dojo/dojo.js"></script>
<script>
require(["dojox/form/CheckedMultiSelect","dijit/form/Button"]);
</script>
<script>
function selectcont()
    {
        var e=document.getElementById("multiselect");
        var str=e.options[e.selectedIndex].value;
    }
    document.write(str);
</script>
<body class="claro">
<select multiple="true" data-dojo-type="dojox/form/CheckedMultiSelect" id="multiselect" >
      <option value="TN">Tennessee</option>
      <option value="VA" selected="selected">Virginia</option>
      <option value="WA" selected="selected">Washington</option>
      <option value="FL">Florida</option>
      <option value="CA">California</option>
 </select>
 <div>
 <button data-dojo-type="dijit/form/Button" type="button" onclick="selectcont()">click me</button>
 </div>
</body>
</html>

// Dojo 1.6    
dijit.byId("multiselect").get('value');

// Dojo >=1.7
require(["dijit/registry"], function(registry){
   registry.byId("multiselect").get('value');
})'

示例下载测试：http: //download.dojotoolkit.org/release-1.9.1/dojo-release-1.9.1/dijit/tests/form/test_MultiSelect.html
