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
