总结JS打印方法

一．用JS自带函数打印

<input >.....文本打印部分.....</div>

Query插件PrintArea完整方法如下：

(function($) {
var printAreaCount = 0;
$.fn.printArea = function()
{
var ele = $(this);
var idPrefix = "printArea_";
removePrintArea( idPrefix + printAreaCount );
printAreaCount++;
var iframeId = idPrefix + printAreaCount;
var iframeStyle = 'position:absolute;width:0px;height:0px;left:-500px;top:-500px;';
iframe = document_createElement_x('IFRAME');
$(iframe).attr({ style : iframeStyle,
id : iframeId
});
document.body.a(iframe);
var doc = iframe.contentWindow.document;
$(document).find("link")
.filter(function(){
return $(this).attr("rel").toLowerCase() == "stylesheet";
})
.each(function(){
doc.write('<link type="text/css" rel="stylesheet" href="' +
$(this).attr("href") + '" >');
});
doc.write('<div class="' + $(ele).attr("class") + '">' + $(ele).html() + '</div>');
doc.close();
var frameWindow = iframe.contentWindow;
frameWindow.close();
frameWindow.focus();
frameWindow.print();
}
var removePrintArea = function(id)
{
$( "iframe#" + id ).remove();
};
})(jQuery);
