.error( handler )Возвращает: jQueryversion deprecated: 1.8, removed: 3.0

Описание: Устанавливает обработчик ошибки при загрузке элементов (например отсутствие необходимой картинки на сервере).

This method is a shortcut for .on( "error", handler ).

As of jQuery 1.8, the .error() method is deprecated. Use .on( "error", handler ) to attach event handlers to the error event instead.

The error event is sent to elements, such as images, that are referenced by a document and loaded by the browser. It is called if the element was not loaded correctly.

For example, consider a page with a simple image element:

<img alt="Book" id="book">

The event handler can be bound to the image:

$( "#book" )
.error(function() {
alert( "Handler for .error() called." )
.attr( "src", "missing.png" );

If the image cannot be loaded (for example, because it is not present at the supplied URL), the alert is displayed:

Handler for .error() called.

The event handler must be attached before the browser fires the error event, which is why the example sets the src attribute after attaching the handler. Also, the error event may not be correctly fired when the page is served locally; error relies on HTTP status codes and will generally not be triggered if the URL uses the file: protocol.

Note: A jQuery error event handler should not be attached to the window object. The browser fires the window's error event when a script error occurs. However, the window error event receives different arguments and has different return value requirements than conventional event handlers. Use window.onerror instead.

Дополнительные замечания:

  • As the .error() method is just a shorthand for .on( "error", handler ), detaching is possible using .off( "error" ).
