ajax gets the return parameters of the page and assigns values ​​to the control

This time I will bring you ajax to get the return parameters of the page and assign values ​​to the control. What are the precautions for ajax to get the return parameters of the page and assign values ​​to the controls? Here is the actual combat Let’s take a look at the case.

js page

$.ajax({
type : "get",
url : "", //跳转页面
data :"m=content&c=favorite&a=del_favorite&shoucangId="+_id,//传递的参数
datatype : "html",
async:'false',
success : function(data) //返回值
{  if(data !=null)
   {
 var str= new Array(); //定义一数组
 str=data.split(","); //字符分割
 var title=str[0];
 var url=str[1];
 var type=str[2];
 var id=str[3];
 $("#title").val(title); // jQuery控件赋值
 $("#url").val(url);
 $("#shoucnag_id").val(id);
 if(type=='钢琴谱')
   $("input[name='radio'][value='钢琴谱']").attr("checked",true);
 else if(type=='钢琴曲')
   $("input[name='radio'][value='钢琴曲']").attr("checked",true);
   }
   else
   {
 alert('失败!');return false;
   }
 }
});

PHP page

$shoucangId=$_GET['shoucangId'];//获取传递的参数
$where="ID='$shoucangId'";
$signalInfo=array();
$signalInfo=$this->db->get_one($where,'*','',''); //此处借用PHPCMS二次开发的例子，select数据库中的一个数据集，存于数组$signalInfo中
if($signalInfo!=null)
{
 $str=$signalInfo['title'].",".$signalInfo['url'].",".$signalInfo['type'].",".$signalInfo['id'];//将要返回的数组用逗号拼接成字符串返回
 exit($str);
}
else
{
 exit('0');
}
