分享一种通用的打印网页、文本内容的方法.经测试，此方法兼容IE8~IE11及chrome浏览器。
window.print()
此方法会弹出打印对话框，打印的是window.document.body.innerHTML中的内容 。
html：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>打印文本内容</title>
<link rel="stylesheet" type="text/css" href="***.css">
</head>
<script type="text/javascript" src="/externals/jquery-1.10.2/jquery-1.10.2.min.js"></script>
<script type="text/javascript" src="/js/affair-detail.js"></script>
<style media="print">
@page{
size:auto; /* auto is the initial value */
margin:0mm; /* this affects the margin in the printer settings */
}
</style>
<body>
<div class="content">
<div class="back">返回</div>
<!--startprint-->
<div class="printBox">
<div class="header">
———
<span>打印内容</span>
———
</div>
</div>
<!--endprint-->
<div class="others">其他内容</div>
<button class="btn" onclick="preview();">打印</button>
</div>
</body>
</html>javascript:
js处理，判断浏览器类型（IE/谷歌）。截取需要打印的部分进行打印，去掉页眉页脚
/**
* 打印文本内容
* */
function preview(){
$('.printBox').css({padding: '30px'}); //针对打印部分进行样式调整，打印完后恢复原内容
bdhtml = window.document.body.innerHTML;
sprnstr = "<!--startprint-->";
eprnstr = "<!--endprint-->";
prnhtml = bdhtml.substr(bdhtml.indexOf(sprnstr) + 17);
prnhtml = prnhtml.substring(0, prnhtml.indexOf(eprnstr));
window.document.body.innerHTML = prnhtml;
if(!!window.ActiveXObject || "ActiveXObject" in window) { //是否ie
remove_ie_header_and_footer();
}
window.print();
window.document.body.innerHTML = bdhtml;
$('.printBox').css({padding: '0'});
}
/**
* 移除页眉页脚
* */
function remove_ie_header_and_footer(){
var hkey_path;
hkey_path = "HKEY_CURRENT_USER\\Software\\Microsoft\\Internet Explorer\\PageSetup\\";
try {
var RegWsh = new ActiveXObject("WScript.Shell");
RegWsh.RegWrite(hkey_path + "header", "");
RegWsh.RegWrite(hkey_path + "footer", "");
} catch(e) {
}
}
