<script src="../jquery-2.1.4.min.js"></script>
<script>
var name='<?php echo urlencode("北京")?>';
var url="http://www.cishop.com/jiekou/jiekou_jsonp1.php?ad_name="+name+"&format=json&jsoncallback=?";
var ar='';
$.getJSON(url,function(msg){
console.log(msg);
var data = eval(msg)
var str ="";
for(var i=0;i<data.length;i++){
str+="<p>"+data[i]["ad_name"]+"</p>"
}
$('#ss').html(str);
})
</script>
<div id='ss'></div>
