Window.print() does not work in firefox 12 version where as the same works in IE

Question

The following is the extract of page source of my application:<br />
<br />
<pre><nowiki><script language='javascript'>
function fncPrint()
document.getElementById("btnPrint").style.visibility="hidden";
document.getElementById("btnClose").style.visibility="hidden";
window.print();
document.getElementById("btnPrint").style.visibility="visible";
document.getElementById("btnClose").style.visibility="visible";
</script>
<td align='center' colspan='10'>
<input type='button' class='button' value='Print' name='btnPrint' onclick='fncPrint()'>
<input type='button' class='button' value='Close' name='btnClose' onclick='window.close()'>
</td>
</nowiki></pre>
This code works fine IE but when used with firefox does nothing, it does not go for printing. I can use Control+P but it will not dim print and close buttons.

Answer 1

You use document.getElementById("btnPrint"), but you only specify the NAME attribute in the input tags and not the ID.<br />
So you will have to add the ID as well to make Firefox find that element.<br />

<pre><nowiki><input type='button' class='button' value='Print' id='btnPrint' name='btnPrint' onclick='fncPrint()'>
<input type='button' class='button' value='Close' id='btnClose' name='btnClose' onclick='window.close()'>
</nowiki></pre>
