关于jquery读取json文件
1 首先建一个json文件，[
{
"name":"张国立",
"sex":"男",
"email":""
},
{
"name":"张铁林",
"sex":"男",
"email":""
},
{
"name":"邓婕",
"sex":"女",
"email":""
}
]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
