为什么Ajax不遵循成功功能？

Question

I have done this hundreds of times and it seemed to work like a charm.But I just can't figure what is wrong with this code.

$.ajax({
        url:"<?php echo base_url() ?>admin/sold_item",
        data:{qty:sold,tprice:sold_price,id:id,uprice:uprice},
        type:"post",
        async:true,
        success:function(msg){

            if(msg=="info_saved"){
                $('#sold_data').html('Your Sold Details Have Been Saved');
                setTimeout("$.colorbox.close()",1500);
              //  setTimeout("window.location.reload()",1800);
            }
            else if(msg=="wrong"){ 
                $('#sold_data').html('Your Information is Incorrect!!Enter Data Again!!');
                setTimeout("$.colorbox.close()",1500);
               // setTimeout("window.location.reload()",1800); 
            }
        }
    })

I am using condition for the response.The php code called by ajax is working perfectly this is the exact code that I am using for ajax.I have alerted the msg variable and firebug console shows the same but the if condition is just not working.What can be the reason.I have tried switch ..case but to no avail.Please somebody see what I am not seeing.

Answer 1

Use the developer tools in chrome and go to the network tab and then select the XHR button at the bottom left of the screen. This will show you exactly what is happening and you can read the response or see an error if there is one.

Answer 2

Your URL seems wrong. admin/sold_item there is no file extension.
