为什么ajax调用不能在相同的URL下正常工作？

Question

There are two ajax calls with same url not working properly?

var ss=35;
function t()
{
$.ajax({type:"POST",
          url:"BillServlet",
          data1:{message1:ss},                                                                 
          success:function(data1){
          alert('success'+data1.message1)
          }});} //this function returns null

function test()
{
$.ajax({type:"POST",
          url:"BillServlet",
          data:{message:total},                                                                 
          success:function(data){
          alert('success'+data.message)
          }});}//this function returns value

Why one function returns null value?

Answer 1

Assuming you're trying to get the same data back from the server in both functions, in function t() you should change data1.message1 to data1.message .

Otherwise, try printing out the value of data1 to see what data the server is actually giving you. If you can't use console.log(data1) for some reason, you could also use alert(JSON.stringify(data1))

Answer 2

Check in the firbug, are you getting the response from server? I think you are getting the blank response from server. If you are getting the response then check the indexes in the response that is it same you are alerting.
