jquery局部打印插件使用

基于jquery库的jquery.PrintArea.js插件源代码为：

 1 (function ($) {
 2     var printAreaCount = 0;
 3     $.fn.printArea = function () {
 4         var ele = $(this);
 5         var idPrefix = "printArea_";
 6         removePrintArea(idPrefix + printAreaCount);
 7         printAreaCount++;
 8         var iframeId = idPrefix + printAreaCount;
 9         var iframeStyle = 'position:absolute;0px;height:0px;left:-500px;top:-500px;';
10         iframe = document.createElement('IFRAME');
11         $(iframe).attr({
12             style: iframeStyle,
13             id: iframeId
14         });
15         document.body.appendChild(iframe);
16         var doc = iframe.contentWindow.document;
17         $(document).find("link").filter(function () {
18             return $(this).attr("rel").toLowerCase() == "stylesheet";
19         }).each(
20                 function () {
21                     doc.write('<link type="text/css" rel="stylesheet" href="'
22                             + $(this).attr("href") + '" >');
23                 });
24         doc.write('<div class="' + $(ele).attr("class") + '">' + $(ele).html()
25                 + '</div>');
26         doc.close();
27         var frameWindow = iframe.contentWindow;
28         frameWindow.close();
29         frameWindow.focus();
30         frameWindow.print();
31     }
32     var removePrintArea = function (id) {
33         $("iframe#" + id).remove();
34     };
35 })(jQuery);
