<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>ajax请求数据并渲染到页面</title>
<style type="text/css">
#test{
width: 100%;

.inner:hover{
border: 1px solid deeppink;

.inner img {

height: 200px;
font-size: 0;
}
h3,

</style>
</head>
<body>
<div id="test">
<!--假数据-->
<!--<div class="inner">

<h3>名称：小米手机</h3>

</div>-->
</div>
</body>
</html>
<script src="http://libs.baidu.com/jquery/2.0.0/jquery.min.js"></script>
<script type="text/javascript">
$(function() {
$.ajax({
type: "GET",
url: "goods.json",
dataType: "json",
success: function(res) {
console.log(res);
console.log(typeof(res));
var data = res.result;
console.log(data);
var str = '';
// 注意：输出的i与obj分别为下标与单个的对象
$.each(data, function(i, obj) {
// console.log(i);
// console.log(obj);
str += '<div class="inner">';
str += '<img src="' + obj.imgUrl + '"/>';
str += '<h3>' + '名称：' + obj.name + '</h3>';
str += '<span>' + '价格：￥' + obj.price + '</span>';
str += '</div>';
});
$("#test").append(str);
}
});
});
</script>3.注意事项
该实例中仅仅有index.html文件，goods.json文件，和一张图片，其中ajax中的url指定json文件的路径（不能写错）。
