// JavaScript Document
(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('IFRAME');

document.body.appendChild(iframe);
iframe.contentWindow.document.write("<html>");  
iframe.contentWindow.document.write('<style media="print">@page {size:  auto; margin: 0mm; } html{margin:0px;} body{margin :0mm 0mm 0mm 0mm;}</style>');  
iframe.contentWindow.document.write("<BODY BGCOLOR=#ffffff>");
iframe.contentWindow.document.write($('#MainFirst_ZHDiagnosisReport_dlg_text').html());
iframe.contentWindow.document.write("</BODY>");
iframe.contentWindow.document.write("</HTML>");
iframe.contentWindow.document.write("<script type='text/javascript'> window.print();<//script>");
iframe.contentWindow.print();
iframe.contentWindow.document.close();

$(iframe).attr({ style : iframeStyle,
id    : iframeId
});
document.body.appendChild(iframe);
var doc = iframe.contentWindow.document;
$(document).find("link")
.filter(function(){
return $(this).attr("rel").toLowerCase() == "stylesheet";
})
.each(function(){
	
//doc.write('<style media="print">@page {size:  auto; margin: 0mm; } html{margin:0px;} body{margin :10mm 15mm 10mm 15mm;}</style>');

doc.write('<link type="text/css" rel="stylesheet" href="' +
$(this).attr("href") + '" >');
});
doc.write($(ele).prop('outerHTML'));
doc.write('<div class="' + $(ele).attr("class") + '">' + $(ele).html() + '</div>');
doc.close();
var frameWindow = iframe.contentWindow;
frameWindow.close();
frameWindow.focus();
//window.print();
//frameWindow.onload = function() {
//    frameWindow.print();
//  };
}
var removePrintArea = function(id)
{
$( "iframe#" + id ).remove();
};
})(jQuery);
