1 首先建一个json文件,[
{ "name":"张国立", "sex":"男", "email":"zhangguoli@123.com" }, { "name":"张铁林", "sex":"男", "email":"zhangtieli@123.com" }, { "name":"邓婕", "sex":"女", "email":"zhenjie@123.com" } ]
2 其次建一个getUserinfo.html页面用于获取JSON文件里的用户信息数据,并显示
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>getJSON获取数据</title> <script type="text/javascript" src="https://code.jquery.com/jquery-3.0.0.min.js"></script> <style type="text/css"> #divframe { border: 1px solid #999; width: 500px; margin: 0 auto; } .loadTitle { background: #CCC; height: 30px; } </style> <script type="text/javascript"> $(function () { $("#btn").click(function () { $.getJSON("js/userinfo.json", function (data) { var $jsontip = $("#jsonTip"); var strHtml = "读取的数据:<br/>";//存储数据的变量 $jsontip.empty();//清空内容 $.each(data, function (haha, info) { strHtml += "姓名:" + info["name"] + "<br>"; strHtml += "性别:" + info["sex"] + "<br>"; strHtml += "邮箱:" + info["email"] + "<br>"; strHtml += "<hr>" }) $jsontip.html(strHtml);//显示处理后的数据 }) }) }) </script> </head> <body> <div id="divframe"> <div class="loadTitle"> <input type="button" value="获取数据" id="btn"/> </div> <div id="jsonTip"> </div> </div> </body> </html>
3 运行效果如下
用浏览器打开getUserinfo.html文件,显示
