我是靠谱客的博主默默老鼠，最近开发中收集的这篇文章主要介绍js通过document.write解决打印问题，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

<script>
function startPrint(obj){
var oWin=window.open("","_blank");
var strPrint='<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=gb2312" /><title>打印预览</title></head><body>';
strPrint=strPrint +"<h4 style='font-size:18px; text-align:center;'>打印预览</h4>n";
strPrint=strPrint + "<script type="text/javascript">n";
strPrint=strPrint + "function printWin()n";
strPrint=strPrint + "{";
strPrint=strPrint +
"var oWin=window.open("","_blank");n";
strPrint=strPrint + "oWin.document.write(document.getElementById("content").innerHTML);n";
strPrint=strPrint + "oWin.focus();n";
strPrint=strPrint + "oWin.document.close();n";
strPrint=strPrint + "oWin.print()n";
strPrint=strPrint + "oWin.close()n";
strPrint=strPrint + "}n";
strPrint=strPrint + "</script>n";
strPrint=strPrint + "<hr size='1'/>n";
strPrint=strPrint + "<div id="content">n";
strPrint=strPrint + '<link href="http://js.3conline.com/pcgames/global.css" type="text/css" rel="stylesheet" /><link href="http://www1.pcgames.com.cn/zt/ssxt/g20120531/css/style.css" type="text/css" rel="stylesheet" /><link href="http://www1.pcgames.com.cn/zt/ssxt/g20120531/css/table.css" type="text/css" rel="stylesheet" /><link href="http://www1.pcgames.com.cn/zt/ssxt/g20120531/css/tableshow.css" type="text/css" rel="stylesheet" /><style type="text/css">body{background:#fff}</style>';
strPrint=strPrint + obj.innerHTML + "n";
strPrint=strPrint + "</div>n";
strPrint=strPrint + "<hr size='1'/>n";
strPrint=strPrint + "<div style='text-align:center'><button οnclick='printWin()' style='padding-left:4px;padding-right:4px;'>打印</button><button οnclick='window.opener=null;window.close();'

strPrint=strPrint + "<body></body></html>";
oWin.document.write(strPrint);
oWin.focus();
oWin.document.close();
}
function a(){
startPrint(document.getElementById("tables2"));
}
</script>
