这是我的剧本
<script type="text/javascript">
function PrintDiv() {
var divContents = document.getElementById("dvContents").innerHTML;
var printWindow = window.open('', '', 'height=200,width=400');
printWindow.document.write('<html><head><title>DIV Contents</title>');
printWindow.document.write('</head><body >');
printWindow.document.write(divContents);
printWindow.document.write('</body></html>');
printWindow.document.close();
printWindow.print();
}
</script>
但是当我点击打印按钮时，打开的窗口会打开但是显示所有字段的内容都是空白的。
