jQuery的图片剪切插件2

imgAreaSelect

imgAreaSelect is a jQuery plugin for selecting a rectangular area of an image. It allows web developers to easily implement image cropping functionality, as well as other user interface features, such as photo notes (like those on Flickr).

Plugin features:

  • Highly configurable
  • Customizable with CSS styling
  • Handles scaled images
  • Keyboard support for moving and resizing the selection
  • Supports callback functions
  • Provides API functions for easier integration with other application components
  • Lightweight — the packed version is less than 8KB

The plugin works in all major browsers, including Firefox 2+, Opera 9.5+, Google Chrome, Safari 3+, and Internet Explorer 6+.

Live Example

Quick Usage Instructions

Download the plugin, unzip it, and copy the JavaScript and CSS files to your website/application directory. Load the files in the <head> section of your HTML document.

<head>
  ...
<linkrel="stylesheet"type="text/css"href="css/imgareaselect-default.css"/><scripttype="text/javascript"src="scripts/jquery.min.js"></script><scripttype="text/javascript"src="scripts/jquery.imgareaselect.pack.js"></script>
  ...
</head>

Then, to enable selection on an image, wrap it in a jQuery object and call the imgAreaSelect() method:

<scripttype="text/javascript">
$(document).ready(function(){    $('img#photo').imgAreaSelect({
        handles:true,
        onSelectEnd: someFunction
    });});</script>
