在以下示例中，您可以看到如何启动dijit/layout/ContentPane并以编程方式调整大小（按下按钮）。

基本上你需要：

使用ContentPane。

registry.byId()

使用dojo setter ContentPane;

.set('propertyName', yourValue)

＆＃13;

require(["dijit/layout/ContentPane", "dijit/registry", "dijit/form/Button", "dojo/domReady!"], function(ContentPane, registry, Button) {
  new ContentPane({
    content: "<p>Optionally set new content now</p>",
    style: "width: 150px; height:150px; background-color:yellow;"
  }, "panelContent").startup();
  var myButton = new Button({
    label: "Click me to enlarge the panel!",
    onClick: function() {
      registry.byId("panelContent").set('style','width: 350px; background-color:red;')
    }
  }, "button").startup();

});

＆＃13;

<link rel="stylesheet" href="//ajax.googleapis.com/ajax/libs/dojo/1.12.1/dijit/themes/claro/claro.css" />

<script>
  window.dojoConfig = {
    parseOnLoad: false,
    async: true
  };
</script>

<script src="//ajax.googleapis.com/ajax/libs/dojo/1.10.1/dojo/dojo.js">
</script>

<body class="claro">
  <div id="panelContent" data-dojo-type="dijit/layout/ContentPane">
    Hi, pretty boring huh?
  </div>
  <button id="button" type="button"></button>
</body>

＆＃13;

Answer 2

这可以通过使用dojo ResizeHandler来实现，因此使用它的setps是：

导入dojox/layout/ResizeHandle
导入resize hander Css Style（用于渲染和调整图标大小）
将您的可调整大小的div portion设置为relative
实例化rsizeHandler并将target设置为div id

所以实例化就像：

var handle = new ResizeHandle({
      targetId:"panelContent"
  }).placeAt("panelContent");

你可以找到一个工作片段

require([
  "dojox/layout/ResizeHandle",
  "dojo/dnd/move",
  'dojo/dom',
  'dojo/domReady!'
], function(ResizeHandle, dojoDnd, Dom) {

  new dojoDnd.parentConstrainedMoveable(Dom.byId("panelContent"),                 {
                    handle: this.focusNode,
                    area: "content",
                    within: true
                })

  var handle = new ResizeHandle({
      targetId:"panelContent"
  }).placeAt("panelContent");
  

});

#panelContent {
  background-color:green;
  position:relative;
  width:200px;
  height:100px;
  cursor:pointer;
}

body,html,#container {
  width:100%;
  height:100%;
}

  window.dojoConfig = {
    parseOnLoad: false,
    async: true
  };
</script>

<div id="container" class="claro">
  <div id="panelContent">
    <div id="handler"></div>
  </div>
