How and What for Did the Deprecated jQuery .Error() Method Work

jQuery error: Main Tips

• The jQuery .error() method was used to trigger an error event.
• It also attached a listener to the error event for jQuery error handling.
• This method was removed in the version 3.0 of jQuery.

Triggering jQuery Errors

The .error() function triggered an error event, or attached a function to run when that event happened. In the example below, see how it displayed jQuery error messages:

$("img").error(() => {
    alert("Error: image could not be loaded!");
});

This was the syntax to trigger jQuery errors:

$("selector").error();

Attaching a listener for jQuery error handling looked like this:

$("selector").error(function);

Note: the jQuery .error() method was deprecated in version 1.8 and removed in 3.0.
