问题描述
我想在按钮点击时打印页面而无需打开新标签。
I want to print the page on button click without opening a new tab.
我有以下几行代码可为我完成这项工作。
I have a following lines of code that does the job for me.
function PrintDiv() {
var contents = document.getElementById("wrapper").innerHTML;
var frame1 = document.createElement('iframe');
frame1.name = "frame1";
frame1.style.position = "absolute";
frame1.style.top = "-1000000px";
document.body.appendChild(frame1);
var frameDoc = frame1.contentWindow ? frame1.contentWindow : frame1.contentDocument.document ? frame1.contentDocument.document : frame1.contentDocument;
frameDoc.document.open();
frameDoc.document.write('<html><head><title>DIV Contents</title>');
frameDoc.document.write('</head><body>');
frameDoc.document.write(contents);
frameDoc.document.write('</body></html>');
frameDoc.document.close();
setTimeout(function () {
window.frames["frame1"].focus();
window.frames["frame1"].print();
document.body.removeChild(frame1);
}, 500);
return false;
}
我在div中使用id wrapper获得打印按钮
I got a print button inside the div with id wrapper
<div id="button-container">
<a href="#" id="PrintDiv" class="btn btn-success btn-primary"><span class="glyphicon glyphicon-print" aria-hidden="true"></span>Print</a>
</div>
我的问题是我无法在打印时隐藏打印按钮。
My problem is I am not being able to hide the print button while printing.
我试过下面几行来隐藏它，但它在我的情况下不起作用。
I have tried following lines to hide but its not working in my case.
$('#PrintDiv').css('visibility', 'hidden');
推荐答案
您需要有基于打印的CSS样式规则 - 您还可以设置其他基于打印的规则 - 例如文档大小，背景颜色，图像规格等等：
You need to have a print based CSS style rule - you can also set other print based rules - such as document size, background color , image specs etc:
@media print {
#button-container{
display: none;
}
}
