这里还要用到一个jqprint-0.3.js
// -----------------------------------------------------------------------

(function($) {
var opt;
$.fn.jqprint = function (options) {
opt = $.extend({}, $.fn.jqprint.defaults, options);
var $element = (this instanceof jQuery) ? this : $(this);
if (opt.operaSupport && $.browser.opera)
{
var tab = window.open("","jqPrint-preview");
tab.document.open();
var doc = tab.document;
}
else
{
var $iframe = $("<iframe />");
if (!opt.debug) { $iframe.css({ position: "absolute", width: "0px", height: "0px", left: "-600px", top: "-600px" }); }
$iframe.appendTo("body");
var doc = $iframe[0].contentWindow.document;
}
if (opt.importCSS)
{
if ($("link[media=print]").length > 0)
{
$("link[media=print]").each( function() {
doc.write("<link type=‘text/css‘ rel=‘stylesheet‘ href=‘" + $(this).attr("href") + "‘ media=‘print‘ />");
});
}
else
{
$("link").each( function() {
doc.write("<link type=‘text/css‘ rel=‘stylesheet‘ href=‘" + $(this).attr("href") + "‘ />");
});
}
}
if (opt.printContainer) { doc.write($element.outer()); }
else { $element.each( function() { doc.write($(this).html()); }); }
doc.close();
(opt.operaSupport && $.browser.opera ? tab : $iframe[0].contentWindow).focus();
setTimeout( function() { (opt.operaSupport && $.browser.opera ? tab : $iframe[0].contentWindow).print(); if (tab) { tab.close(); } }, 1000);
}
$.fn.jqprint.defaults = {
debug: false,
importCSS: true,
printContainer: true,
operaSupport: true
};
// Thanks to 9__, found at http://users.livejournal.com/9__/380664.html
jQuery.fn.outer = function() {
return $($(‘<div></div>‘).html(this.clone())).html();
}
})(jQuery);
可以直接调用jqprint-0.3.js，这样做是为了在提交数据的时候直接打印，等于后台打印，就不要重新打开一个预览页面
