html文件，demo.html

<div>
	
	<div>最外层需要用div标签括起来</div>
	
</div>

js文件，demo.js

define([
	"dojo/_base/declare","dijit/_WidgetBase","dijit/_TemplatedMixin","dijit/_WidgetsInTemplateMixin","dojo/text!html文件的路径/demo.html"
],function(declare,_WidgetBase,_TemplatedMixin,_WidgetsInTemplateMixin,template) {
	return declare([_WidgetBase,_WidgetsInTemplateMixin],{
		templateString: template,constructor: function() {
			this.inherited(arguments);
		},postCreate: function() {
			this.inherited(arguments);
		}
	});
});

模板的使用，在模板中调用模板也是一样的写法

require([
	"js文件的路径/demo"
],function(demo) {
	var oDemo = new Demo();
});
