How Can I Prevent jQuery AJAX Requests from Freezing with a Timeout?

Set Timeout for jQuery AJAX Requests

The given code snippet shows an AJAX request using jQuery, but sometimes the success function does not reliably trigger. To address this, a timeout can be set to automatically handle errors if the request does not complete within the specified time.

Solution:

To set a timeout for an AJAX request, use the timeout option in the $.ajax method. This option specifies the time in milliseconds before the request is considered a timeout. If the request takes longer than the specified time, the error function will be triggered with a "timeout" status.

$.ajax({
    url: "test.html",
    error: function(){
        // Will fire when timeout is reached or other error occurs
    },
    success: function(){
        // Do something
    },
    timeout: 3000 // Sets timeout to 3 seconds
});

By setting the timeout option, the AJAX request will no longer freeze the execution indefinitely if the server is down or unresponsive. The error function can then be used to handle the timeout and display an error message or take other appropriate actions.

Additionally, the error function can receive the textStatus parameter, which contains the type of error that occurred. If the timeout was reached, textStatus will be set to "timeout".
