Dojo
Dojo是一個用javascript語言實現的開源DHTML工具包。它是在幾個項目捐助基礎上建立起來的(nWidgets,Burstlib,f(m)),這也是為什麼叫它a"unified"toolkit的原因。Dojo的目標是解決開發DHTML應用程序遇到的那些,長期存在、歷史問題(historical problems with DHTML)。跨浏覽器問題。
1、問題背景
這裡有一個下拉框,其中選項為一年四季,選中後打印下拉框的值和文本
2、實現源碼
<!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <title>dojo-獲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'))">獲取下拉框value</button> <button id="textBtn" onclick="alert(dijit.byId('season').get('displayedValue'))">獲取下拉框text</button> </body> </html>
3、實現結果
(1)初始化時
(2)點擊“獲取下拉框value”按鈕
(3)點擊“獲取下拉框text”按鈕
