How Can I Retrieve the Error Response Text from jQuery's $.ajax?

Retrieving the Error Response Text in jQuery's $.ajax

In asynchronous communication, handling error responses is crucial to provide meaningful user feedback. When using jQuery's $.ajax method to send requests, it's possible to retrieve the error response text, which can contain valuable information about the occurred error.

In the provided code example, the PHP code is generating an error response with a custom message ("Gone to the beach"). However, the jQuery.ajax error handler only logs "error" without providing the detailed response text.

To resolve this issue and access the error response text, you can modify the error callback function to use the following syntax:

error: function(xhr, status, error) {
  var err = eval("(" + xhr.responseText + ")");
  alert(err.Message);
}

In this revised code, the received error response text is parsed as JSON using the eval function. The parsed JSON object contains a property called Message that holds the custom error message generated by the server. By logging or displaying this Message property, you can inform users about the specific reason for the request failure.

This solution allows you to retrieve the detailed error response text and handle it in a meaningful way, providing a better user experience for your application.
