Determine if $.ajax error is a timeout

Determine if $.ajax error is a timeout

🤔 So you're using the magical powers of jQuery.ajax( settings ) but you're wondering about the timeout setting. 🕑 Can it trigger anything when the timeout is reached or does it simply stop listening for a response? 🤷‍♂️

According to the jQuery site, the timeout setting seems pretty straightforward - it's used to specify the local time for a request, but it doesn't seem to have any built-in functionality when the timeout is reached. 😮

But fear not! 💪 If you want to trigger an alert or some other function when the timeout occurs, there's a solution for you.

First, let's take a look at the snippet you provided:

$("form#testform").submit(function(){ 

   var allFormValues = $("form#testform").serialize(); 

   $.ajax({
      cache:false,
      timeout:8000,  // I chose 8 secs for kicks
      type:"POST",
      url:"someurl.php",
      data:allFormValues,
      error:function(){ alert("some error occurred") },
      success:function(response){ alert(response); }
   });

});

In this example, the timeout is set to 8000 milliseconds (8 seconds). However, the error setting is not triggered when the timeout is reached. 😕

But don't worry, we can solve this issue by using the statusCode property of the settings object in the ajax function.

You can modify your code like this:

$("form#testform").submit(function(){ 
  
  var allFormValues = $("form#testform").serialize(); 
  
  $.ajax({
    cache:false,
    timeout:8000,
    type:"POST",
    url:"someurl.php",
    data:allFormValues,
    success:function(response){ alert(response); },
    statusCode: {
      404: function() {
        alert("Page not found");
      },
      500: function() {
        alert("Internal server error");
      },
      // Add more status codes and corresponding functions if needed
    },
    error: function(xhr, textStatus, errorThrown){
      if(textStatus === "timeout"){
        alert("Timeout error occurred");
      } else {
        // Handle other error cases here
      }
    }
  });
  
});

In the updated code, we have added the statusCode property inside the ajax function. This property allows us to handle specific HTTP status codes and execute corresponding functions.

Additionally, we modified the error function to check if the textStatus is equal to "timeout". If it is, we display our custom timeout error message. 🚀

Feel free to add more status codes and their corresponding functions in the statusCode object, depending on your needs.

So, there you have it! You can now easily determine if a $.ajax error is a timeout and handle it accordingly. ⏰✨
