This method is a shortcut for .bind('error', handler).
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:
<img src="missing.png" alt="Book" id="book" />
The event handler can be bound to the image:
$('#book').error(function() {
alert('Handler for .error() called.')
});
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.
This event may not be correctly fired when the page is served locally. Since
errorrelies on normal HTTP status codes, it will generally not be triggered if the URL uses thefile: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.
示例:
To hide JavaScript errors from the user, you can try:
jQuery 代码:
$(window).error(function(){
return true;
});示例:
To hide the "broken image" icons for your IE users, you can try:
jQuery 代码:
$("img").error(function(){
$(this).hide();
});
