<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>使用getJSON()方法异步加载JSON格式数据</title> <script src="http://libs.baidu.com/jquery/1.9.0/jquery.js" type="text/javascript"></script> </head> <body> <div id="divtest"> <div class="title"> <span class="fl">我最喜欢的一项运动</span> <span class="fr"> <input id="btnShow" type="button" value="get" /> </span> </div> <ul></ul> </div> <script type="text/Javascript"> $(function () { $("#btnShow").bind("click", function () { var $this = $(this); $.getJSON("http://localhost:8080/news/ShowNewsService", function (data){ $this.attr("disabled", "false"); $.each(data, function (key, dataList) { for(var i=0; i<dataList.length; i++) $("ul").append("<li>" + dataList[i].newsUrl + "</li>"); }); }); }); }); </script> </body></html>
