打印DIV内容的最佳方法是什么?
当前回答
function printdiv(printdivname) {
var headstr = "<html><head><title>Booking Details</title></head><body>";
var footstr = "</body>";
var newstr = document.getElementById(printdivname).innerHTML;
var oldstr = document.body.innerHTML;
document.body.innerHTML = headstr+newstr+footstr;
window.print();
document.body.innerHTML = oldstr;
return false;
}
这将打印您想要的div区域,并将内容设置为原来的内容。Printdivname是要打印的div。

我修改了@BillPaetski答案使用querySelector,添加可选的CSS,删除强制H1标签,并使标题可选地指定或从窗口拉出。它也不再自动打印,并公开内部内容,以便它们可以在包装器函数中切换或随你喜欢。
仅有的两个私有变量是tmpWindow和tmpDoc,尽管我相信标题,css和elem访问可能会有所不同,但应该假设所有函数参数都是私有的。
Code:function PrintElem(elem, title, css) {
var tmpWindow = window.open('', 'PRINT', 'height=400,width=600');
var tmpDoc = tmpWindow.document;
title = title || document.title;
css = css || "";
this.setTitle = function(newTitle) {
title = newTitle || document.title;
};
this.setCSS = function(newCSS) {
css = newCSS || "";
};
this.basicHtml5 = function(innerHTML) {
return '<!doctype html><html>'+(innerHTML || "")+'</html>';
};
this.htmlHead = function(innerHTML) {
return '<head>'+(innerHTML || "")+'</head>';
};
this.htmlTitle = function(title) {
return '<title>'+(title || "")+'</title>';
};
this.styleTag = function(innerHTML) {
return '<style>'+(innerHTML || "")+'</style>';
};
this.htmlBody = function(innerHTML) {
return '<body>'+(innerHTML || "")+'</body>';
};
this.build = function() {
tmpDoc.write(
this.basicHtml5(
this.htmlHead(
this.htmlTitle(title) + this.styleTag(css)
) + this.htmlBody(
document.querySelector(elem).innerHTML
)
)
);
tmpDoc.close(); // necessary for IE >= 10
};
this.print = function() {
tmpWindow.focus(); // necessary for IE >= 10*/
tmpWindow.print();
tmpWindow.close();
};
this.build();
return this;
}
Usage:
DOMPrinter = PrintElem('#app-container');
DOMPrinter.print();
我认为有更好的解决办法。让你的div打印覆盖整个文档,但只在打印时:
@media print {
.myDivToPrint {
background-color: white;
height: 100%;
width: 100%;
position: fixed;
top: 0;
left: 0;
margin: 0;
padding: 15px;
font-size: 14px;
line-height: 18px;
}
}
从这里https://forums.asp.net/t/1261525.aspx
<html>
<head>
<script language="javascript">
function printdiv(printpage) {
var headstr = "<html><head><title></title></head><body>";
var footstr = "</body>";
var newstr = document.all.item(printpage).innerHTML;
var oldstr = document.body.innerHTML;
document.body.innerHTML = headstr + newstr + footstr;
window.print();
document.body.innerHTML = oldstr;
return false;
}
</script>
<title>div print</title>
</head>
<body>
//HTML Page //Other content you wouldn't like to print
<input name="b_print" type="button" class="ipt" onClick="printdiv('div_print');" value=" Print ">
<div id="div_print">
<h1 style="Color:Red">The Div content which you want to print</h1>
</div>
//Other content you wouldn't like to print //Other content you wouldn't like to print
</body>
</html>
与最佳答案相同,以防你需要像我一样打印图像:
如果你想打印图像:
function printElem(elem)
{
Popup(jQuery(elem).attr('src'));
}
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('</head><body >');
mywindow.document.write('<img src="'+data+'" />');
mywindow.document.write('</body></html>');
mywindow.print();
mywindow.close();
return true;
}
在Opera中,试试:
print_win.document.write('</body></html>');
print_win.document.close(); // This bit is important
print_win.print();
print_win.close();
