Javascript打印弹出窗口适用于Firefox / Chrome但不适用于Internet Explorer

Question

The following lines of code create an html page in a browser popup and then prints the popup for the user:

function printPage(htmlPage)
{
   var w = window.open("about:blank");
   w.document.write(htmlPage);
   w.print();
}

This code successfully opens a print dialog in both Firefox and Chrome. However, in IE, no print dialog is displayed. Any suggestions?

I've also tried closing the popup after calling print(), as others have suggested fixes the issue:

function printPage(htmlPage)
{
   var w = window.open("about:blank");
   w.document.write(htmlPage);
   w.print();
   w.close();
}

To no avail.

Answer 1

close() the document before you try to print() .

function printPage(htmlPage) 
{ 
   var w = window.open("about:blank"); 
   w.document.write(htmlPage);
   w.document.close();
   w.print(); 
} 

Works in IE9 .
