1、问题背景
这里有一个下拉框，其中选项为一年四季，选中后打印下拉框的值和文本
2、实现源码
- <!DOCTYPE html>
- <html>
- <head>
- <Meta charset="utf-8" />
- <title>dojo-获取下拉框的值和文本</title>
- <link rel="stylesheet" href="js/dojo/dijit/themes/claro/claro.css" />
- <script type="text/javascript" src="js/jquery-1.12.4.js"></script>
- <script type="text/javascript" src="js/dojo/dojo/dojo.js"></script>
- <style>
- #season{
- width:200px;
- }
- </style>
- <script>
- dojoConfig={async:true,parSEOnLoad:true}
- </script>
- <script>
- require([
- "dojo/store/Memory","dijit/form/FilteringSelect","dojo/domReady!"
- ],function(Memory,FilteringSelect){
- var seasonStore = new Memory({
- data: [
- {name:"春季",id:"spring"},{name:"夏季",id:"summer"},{name:"秋季",id:"autumn"},{name:"冬季",id:"winter"}
- ]
- });
- var seasonSelect = new FilteringSelect({
- id: "season",name: "season",value: "spring",store: seasonStore,searchAttr: "name"
- },"season").startup();
- });
- </script>
- </head>
- <body class="claro">
- <input id="season" /><br>
- <button id="valueBtn" onclick="alert(dijit.byId('season').get('value'))">获取下拉框value</button>
- <button id="textBtn" onclick="alert(dijit.byId('season').get('displayedValue'))">获取下拉框text</button>
- </body>
- </html>
3、实现结果
（1）初始化时
（2）点击“获取下拉框value”按钮
（3）点击“获取下拉框text”按钮
