Window title for javascript print

Found this code to print a javascript element that I modified. Although I added the document.title and the <title></title> tags, the window that opens in the regular text editor says untitled.

This is usually the situation before the text is saved. Is there a way to show a title anyway?

    var element=document.getElementById(element_id);
    var newWin=window.open('','Print-Window','width=400,height=400,top=100,left=100');

    newWin.document.open();
    newWin.document.title = "Readings on PageLinks";
    newWin.document.write('<html><head><title>'+newWin.document.title+'</title></head><body   onload="window.print()">'+element.innerHTML+'</body></html>');
    newWin.document.close();

    setTimeout(function(){ newWin.close(); },10);

It could be a behavior of the editor that's opened with the document. Until the document is saved, the editor header will say "untitled". This must be by design.

Actually the original code worked for me as well (Chrome, didn't test on other browsers)

var element_id = "id1";
var element = document.getElementById(element_id);
var newWin = window.open('', 'Print-Window', 'width=400,height=400,top=100,left=100');

newWin.document.open();
newWin.document.title = "Readings on PageLinks";
newWin.document.write('<html><head></head><body onload="window.print()">' + element.innerHTML + '</body></html>');
newWin.document.close();

setTimeout(function() {
    newWin.close();
}, 10);​

See on JSFiddle

My guess is that the assignment newWin.document.title = "Readings on PageLinks"; failed, because there was no <title> element in the page at that time.

Thus, newWin.document.title was still undefined. Then you concatenated it to the string <title>'+newWin.document.title+'</title>, so it got toString()-ed as "undefined".

So, just write the title directly into the string

newWin.document.write('<html><head><title>Readings on PageLinks</title>...');

as Eran Medan suggested in the comments.

This worked for me.
