我需要提供选项来打印网页的一部分。这是使用 javascript window.print() 实现的回答者:Bill Paetzke。 弹出窗口打开(这包含 CSS 样式)并且打印对话框也打开。但是 CSS 样式并没有出现在打印中。 试过 @media =print 但这也不起作用。 CSS样式主要由背景色组成。我得到的一个选择是用 1px * 1px 的图像替换背景颜色并重复它。还有其他办法吗？
浏览器:IE7 代码:
<html>
<head>
<style type="text/css" media="print,screen">
.hideMe{
display:block;
}
.PrintClass {
display:block;
}
.NoPrintClass{
display:block;
}
</style>
<script type="text/javascript"
src="http://jqueryjs.googlecode.com/files/jquery-1.3.1.min.js"> </script>
<script type="text/javascript">
function PrintElem(elem)
{
Popup($('<div/>').append($(elem).clone()).html());
}
function Popup(data)
{
var mywindow;
mywindow = window.open('', 'mydiv','height=400,width=600,scrollbars=yes','');
mywindow.document.write('<html><head><title>my div</title>');
mywindow.document.write('<style type="text/css" media="print,screen">.hideMe{display:none;}.NoPrintClass{display:none;}</style>');
mywindow.document.write('</head><body>');
mywindow.document.write('drop down selected value in parent: '+mywindow.opener.document.getElementById('testSelect').options[mywindow.opener.document.getElementById('testSelect').selectedIndex].text+'<br/>');
mywindow.document.write('contentStarts<br/>');
mywindow.document.write(' using jquery: '+data);
mywindow.document.write(' using javascript: '+mywindow.opener.document.getElementById('mydiv').innerHTML);
mywindow.document.write('<br/>contentEnds');
mywindow.document.write('<br/>');
mywindow.document.write('</body></html>');
mywindow.document.focus();
mywindow.document.close();
mywindow.print();
return true;
}
</script>
</head>
<body>
This is not be printed<br/>
<div id="mydiv">This content is to be printed<br/>
<div class="hideMe"><select id="testSelect">
<option>1</option>
<option>2</option>
<option>3</option>
</select>
</div>
<br/>
This will also be printed

</img>
</text>
</div>
<div>This will not be printed.</div>
<br/>
<div id="anotherdiv">Nor will this.</div>
<input type="button" value="Print Div" onclick="PrintElem('mydiv')" />
</body>
</html>
最佳答案
因为您正在使用没有任何样式 id 的 html 编写文档 这意味着它只写 div 的内容，周围没有 div。
用它来获取整个div
$('<div/>').append($(elem).clone()).html();
查看此 fiddle
HTML
<div id="mydiv">
This will be printed. Lorem ipsum dolor sit amet, consectetur adipiscing elit. Pellentesque a quam at nibh adipiscing interdum. Nulla vitae accumsan ante.
</div>
<div>
This will not be printed.
</div>
<div id="anotherdiv">
Nor will this.
</div>
<input type="button" value="Print Div" onclick="PrintElem('#mydiv')" />
JavaScript
function PrintElem(elem)
{
Popup($('<div/>').append($(elem).clone()).html());
}
function Popup(data)
{
var mywindow = window.open('', 'my div', 'height=400,width=600');
mywindow.document.write('<html><head><title>my div</title>');
mywindow.document.write('<link rel="stylesheet" href="http://www.dynamicdrive.com/ddincludes/mainstyle.css" type="text/css" />');
mywindow.document.write('</head><body >');
mywindow.document.write(data);
mywindow.document.write('</body></html>');
mywindow.print();
// mywindow.close();
return true;
}
