How Can I Retrieve the Specific Error Message from a jQuery $.ajax Error Response?

Retrieve jQuery $.ajax Error Response Text

Problem:

When sending an error response to jQuery, retrieving the response text (the actual error message) remains elusive. The error event handler only provides a generic "error" message, leaving you in the dark about the specific issue.

Solution:

To access the error response text, you can use the following approach:

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

Explanation:

In this code:

1. xhr is the XMLHttpRequest object that contains the response from the server.
2. responseText is a property of xhr that contains the server's response as a string.
3. To extract the error message from the response string, we evaluate the string using eval(), which treats it as JavaScript code.
4. The evaluated code is placed in a variable called err, which is an object containing the error properties, such as Message.
5. We can then access and display the specific error message using err.Message.

By following this approach, you can obtain the detailed error response text and handle the error more effectively.
