javascript - registry.byID 设置内容返回无法获取未定义或空引用的属性 'set'

Question

尝试使用registry.byId 设置内容 Pane 的内容，但我无法获取该对象 - 我收到以下错误:

JavaScript 运行时错误:无法获取未定义或 null 引用的属性“集”

我的代码是这样的:

 require(["dojo/parser", "dojo/dom", "dijit/registry", 
"dojox/layout/ContentPane", "dojo/domReady!"],
 function (parser, dom, registry) {

parser.parse();

registry.byId("Content").set("content", "Test Content");//Content ID is not being found

 });

</script>
<div data-dojo-type="dijit/layout/BorderContainer" id="Main" style="width: 100%; height: 100%">
 <div data-dojo-type="dojox/layout/ContentPane" id="TOC" data-dojo-props="splitter: true, region:'leading'">
 TOC
 </div>
 <div data-dojo-type="dojox/layout/ContentPane" id="Content" data-dojo-props="splitter: true, region:'center'">
 </div> 

有什么想法吗？谢谢!

我认为小部件正在创建过程中，当您调用 registry.byId() 调用时，它们尚未准备好。

您需要通过包含“dojo/ready”模块在ready()调用中添加初始化代码。

require(["dojo/parser", "dojo/dom", "dijit/registry", "dojo/ready",
          "dojox/layout/ContentPane"],
function (parser, dom, registry, ready) {

   parser.parse();
   ready( function(){

      // your code goes here.
      registry.byId("Content").set("content", "Test Content");

   });
}

});
