来自PHP结果的jQuery json

Question

I have this jQuery script

var dataString = "class_id="+class_id;

$.ajax({
    type: "POST",
    url: "page.php",
    data: dataString,
    success: function (msg) {
        //stuck here
    },
    error: function () {
        showNotification("error", "Could not process at this time, try again later."); //this is a function created by me (which works fine so I just left the code in here)
    }
});

my PHP output is something like this

echo '{status:1,message:"Success"}';

or

echo '{status:0,message:"Failure"}';

what I am trying to do in jQuery success: function(...) part is check if status is 0 or 1 and then show the message.

I tried to do is

success: function(text) {
   if(parseInt(text.status) == 1) {
      alert(text.message); // this is the success, the status is 1
   } else {
      alert(text.message); // this is the failure since the status is not 1
   }
}

which didn't work, it was only outputing the else statement, even though the status was 1

Try something like below,

$.ajax({
    type: "POST",
    url: "page.php",
    data: dataString,
    dataType: 'json',
    success: function (msg) {
        if (msg.status == 0) {
          alert("Success " + msg.message);
        } else if (msg.status == 1) {
          alert("Error " + msg.message);
        }
    },
    error: function () {
        showNotification("error", "Could not process at this time, try again later."); //this is a function created by me (which works fine so I just left the code in here)
    }
});
