javascript - window.print not working in Firefox

asked Oct 24, 2021 in Technique[技术] by 深蓝 (71.8m points)

function CallPrint() {
        var prtContent = document.getElementById('<%= pnlDelete.ClientID %>');
        var winPrint = window.open('', '', 'left=0,top=0,width=800,height=600,toolbar=0,scrollbars=0,status=0');
        winPrint.document.write("<h3>Summary</h3><br />" + prtContent.innerHTML);
        winPrint.document.close();
        winPrint.focus();
        winPrint.print();
        winPrint.close();
    }

I have a need where I have to print contents of a div. I am using above code to do so. It is working fine in IE but does nothing in Firefox. Am I missing something here that needs to be done in Firefox?

Instead of opening a new window without any URL, I opened this page in the window and accessed the contents of the pnlSummary from the opened window via window.opener object –

function CallPrint() {
    var winPrint = window.open('Print.aspx', '', 'left=0,top=0,width=800,height=600,toolbar=0,scrollbars=0,status=0');
}

On Print.aspx page I used this function –

function Print() {
    var prtContent = "<h3>Summary</h3>" + window.opener.document.getElementById('ctl00_cphContent_pnlSummary').innerHTML;
    document.getElementById("printDiv").innerHTML = prtContent;
    window.print();
    window.opener.focus();
    window.close(); }

and called it on body onload.

<body onload="Print();">
    <form id="form1" runat="server">
    <div id="printDiv">
    </div>
    </form>
</body>

This is working fine in both IE and Firefox.
