The reason why the internal value of ajax cannot be called externally and the solution

var id=‘123';
$.ajax({   
        url:'http://www.xxx.com/ajax',   
        type:'post',
        dataType: "json",
        data:{wurl:w_url,murl:m_url}, 
        async : turn, 
        error:function(){  
        },
        success:function(data){
          var id= data[‘id'];
          console.log(id) // 这里出来的是100
   
         }
      })
      console.log(id); //这里出来的是123

The problem lies in the async synchronization step option of ajax. If async: false, means running in synchronous mode, and then execute the following statement after ajax loading is completed. If async: turn, it means asynchronous execution. If ajax does not reach the value, it will have the opportunity to receive the next statement of ajax.
