Ken*_*hou 64 javascript jquery
JavaScript代码window.print()可以打印当前的HTML页面.
如果我在HTML页面中有一个div(例如,从ASP.NET MVC视图呈现的页面),那么我只想打印div.
是否有任何jQuery 不引人注目的JavaScript或普通的JavaScript代码来实现此请求？
更清楚地说,假设呈现的HTML页面如下:
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head" runat="server">
<title>
<asp:ContentPlaceHolder runat="server" ID="TitleContent" />
</title>
</head>
<body>
<div id="div1" class="div1">....</div>
<div id="div2" class="div2">....</div>
<div id="div3" class="div3">....</div>
<div id="div4" class="div4">....</div>
<div id="div4" class="div4">....</div>
<p>
<input id="btnSubmit" type="submit" value="Print" onclick="divPrint();" />
</p>
</body>
</html>
然后我想点击打印按钮,只打印div3.

我会有点像这样:
<html>
<head>
<title>Print Test Page</title>
<script>
printDivCSS = new String ('<link href="myprintstyle.css" rel="stylesheet" type="text/css">')
function printDiv(divId) {
window.frames["print_frame"].document.body.innerHTML=printDivCSS + document.getElementById(divId).innerHTML;
window.frames["print_frame"].window.focus();
window.frames["print_frame"].window.print();
}
</script>
</head>
<body>
<h1><b><center>This is a test page for printing</center></b><hr color=#00cc00 width=95%></h1>
<b>Div 1:</b> <a href="javascript:printDiv('div1')">Print</a><br>
<div id="div1">This is the div1's print output</div>
<br><br>
<b>Div 2:</b> <a href="javascript:printDiv('div2')">Print</a><br>
<div id="div2">This is the div2's print output</div>
<br><br>
<b>Div 3:</b> <a href="javascript:printDiv('div3')">Print</a><br>
<div id="div3">This is the div3's print output</div>
<iframe name="print_frame" width="0" height="0" frameborder="0" src="about:blank"></iframe>
</body>
</html>

与您需要至少执行以下操作的一些建议相同:
一个示例CSS可以像这样简单:
@media print {
body * {
display:none;
}
body .printable {
display:block;
}
}
然后,您的JavaScript只需要将"可打印"类应用于目标div,并且在打印时它将是唯一可见的(只要没有其他冲突的CSS规则 - 单独的练习).
<script type="text/javascript">
function divPrint() {
// Some logic determines which div should be printed...
// This example uses div3.
$("#div3").addClass("printable");
window.print();
}
</script>
您可能希望在打印发生后从目标中删除该类,和/或在打印完成后删除动态添加的CSS.
下面是一个完整的工作示例,唯一的区别是打印CSS没有动态加载.如果你想要它真的不引人注目,那么你需要动态加载CSS,就像在这个答案中一样.

试试这个JavaScript代码:
function printout() {
var newWindow = window.open();
newWindow.document.write(document.getElementById("output").innerHTML);
newWindow.print();
}
<div id="invocieContainer">
<div class="row">
...Your html Page content here....
</div>
</div>
<script src="/Scripts/printThis.js"></script>
<script>
$(document).on("click", "#btnPrint", function(e) {
e.preventDefault();
e.stopPropagation();
$("#invocieContainer").printThis({
debug: false, // show the iframe for debugging
importCSS: true, // import page CSS
importStyle: true, // import style tags
printContainer: true, // grab outer container as well as the contents of the selector
loadCSS: "/Content/bootstrap.min.css", // path to additional css file - us an array [] for multiple
pageTitle: "", // add title to print page
removeInline: false, // remove all inline styles from print elements
printDelay: 333, // variable print delay; depending on complexity a higher value may be necessary
header: null, // prefix to html
formValues: true // preserve input/form values
});
});
</script>
