先看效果截图：
js-依赖jquery
<script src="https://cdn.bootcss.com/jquery/3.2.1/jquery.js"></script>
<script type="text/javascript">
$(function(){
$('#btn').on('click',function () {
var thishtml=""
$.ajax({
url: 'data_list.html',//这里直接放data_list.json也可以
dataType:'json',method: 'get',success: function (data) {
console.log(data)
//单个获值
//var na = (data[0].name)
//$(".panel").append(na);
//遍历出来 格式：jQuery.each(object,[callback])
$.each(data,function(i,item){
thishtml+="姓名："+item["name"]+"<br>";
thishtml+="性别："+item["sex"]+"<br>";
thishtml+="邮箱："+item["email"]+"<br>"; //strHtml反复拿值做字符串拼接
alert(thishtml)
thishtml+="<hr>"
})
//塞到页面的dom中
$(".panel").html(thishtml);
},error:function(){
alert("error!");
}
})
})
})
</script>
data_list.html-上面的ajax取的数据源， 其实就是一个空白的html，里面放的json
[
{
"name":"张国立","sex":"男","email":"zhangguoli@123.com"
},{
"name":"张铁林","email":"zhangtieli@123.com"
},{
"name":"邓婕","sex":"女","email":"zhenjie@123.com"
}
]
主页面html
<input type="button" name="" id="btn" value="加载" /> <div class="panel"> </div>
