Dojo
Dojo是一個(gè)用javascript語(yǔ)言實(shí)現(xiàn)的開(kāi)源DHTML工具包。它是在幾個(gè)項(xiàng)目捐助基礎(chǔ)上建立起來(lái)的(nWidgets,Burstlib,f(m)),這也是為什么叫它a"unified"toolkit的原因。Dojo的目標(biāo)是解決開(kāi)發(fā)DHTML應(yīng)用程序遇到的那些，長(zhǎng)期存在、歷史問(wèn)題(historical problems with DHTML)。跨瀏覽器問(wèn)題。
1、問(wèn)題背景
這里有一個(gè)下拉框，其中選項(xiàng)為一年四季，選中后打印下拉框的值和文本
2、實(shí)現(xiàn)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(shí)現(xiàn)結(jié)果
（1）初始化時(shí)
（2）點(diǎn)擊“獲取下拉框value”按鈕
