给div动态添加按标签，a标签里套的是img

[lyyliyuanyuan]

<div class="table" id="tableid">
<a class="small_active" href="javascript:;"><img src="images/s1.jpg" width="50" height="50" alt=""/></a>
<a href="javascript:;"><img src="images/s2.jpg" width="50" height="50" alt=""/></a>
<a href="javascript:;"><img src="images/s3.jpg" width="50" height="50" alt=""/></a>
</div>


怎么把img src 的路径改为动态获取，我是这样写的，但图片路径未获取
$.ajax({
url:"http://127.0.0.1:8080/PATROL/seam/mhgis?action=buildinfoAction&method=houseimg",
type:"post",
datatype:"json",
data:{"id":1},
async: false,
success:function(data){
var powers=eval("("+data+")");
console.log(powers);
var count=powers.items.length;
if(count>0){
$("#tableid").append('<a class="small_active" href="javascript:;" ><img src="'+powers.items[0].PATH+'" width="50" height="50" alt=""/></a>');
for(var i=0;i<count;i++){
$("#tableid").append('<a href="javascript:;" ><img src="'+powers.items[i+1].PATH+'" width="50" height="50" alt=""/></a>');

}

}

}

});

首先你要确定 powers.items[i+1].PATH 有值，你可以用日志 console.log() 来查看是否取到了值。这个日志会在浏览器开发人员工具的控制台里显示

$.ajax({
	url: "http://127.0.0.1:8080/PATROL/seam/mhgis?action=buildinfoAction&method=houseimg",
	type: "post",
	dataType: "json",
	data: {"id": 1},
	async: false,
	success: function(powers) {
		console.log(powers);
		var count = powers.items.length;
		if (count > 0) {
			$("#tableid").append('<a class="small_active" href="javascript:;" ><img src="' + powers.items[0].PATH + '" width="50" height="50" alt=""/></a>');
			for (var i = 1; i < count; i++) {
				$("#tableid").append('<a href="javascript:;" ><img src="' + powers.items[i].PATH + '" width="50" height="50" alt=""/></a>');
			}
		}
	}
});
