jQuery Deprecated Feature: How to Resolve \'event.returnValue\' Warning

jQuery: Event.returnValue is Deprecated

Question:

When using jQuery v1.10.2, a warning appears in the Google Chrome console: "event.returnValue is deprecated. Please use the standard event.preventDefault() instead." Can you identify the issue and provide a solution?

Background:

The provided code utilizes jQuery to toggle the visibility of a resume status upon a button click. The error occurs within the event handler for the "changeResumeStatus" element, which is specified as a element.

Response:

The warning indicates that the use of event.returnValue is outdated. This method is being phased out and should be replaced with the standardized event.preventDefault() function.

Resolution:

To resolve the issue, update your code to use event.preventDefault() instead of event.returnValue. Here's the modified event handler:

$("#changeResumeStatus").click(function (event) {
    $.get("{% url 'main:changeResumeStatus' %}", function (data) {
        if (data['message'] == 'hidden') {
            $("#resumeStatus").text("скрыто");
        } else {
            $("#resumeStatus").text("опубликовано");
        }
    }, "json");
    event.preventDefault(); // Added to prevent default action
});

This change will eliminate the deprecation warning and ensure that the event handler operates smoothly.
