New Browser Window

[Whizzz]

Hi,

Although I get by with coding for what I need on my web pages, and spend enormous amounts of hours doing so, I am now asking for some help.

I wish to call for a new window in a browser when clicking on the option value in the code below. This drop and go link list box works fine and it calls for the web page, but I need a new browser window to come up after clicking.

I tried 100, and I mean 100 things, and searched for tutorials but no luck.

Here's the code;

<select name="DropGoCombo0" onChange="GoNow0(this.form)" size=1>
<option value=http://pcchill.com/xcart/catalog/Seal-String-p-35.html>Seal String
<option value="4.html">test
<option value="5.html">test
<option value="" selected>(VIEW & ADD COOLING ACCESSORIES TO CART)
</select>



</BODY>
<script language="JavaScript">
<!--
function GoNow0(Form){
var i=Form.DropGoCombo0.selectedIndex;
var g=Form.DropGoCombo0.options[i].value;
if (g!="") parent.location=g;
}
//------>

</script>

</HTML>



Any help would be very much appreciated.

<option value=http://pcchill.com/xcart/catalog/Seal-String-p-35.html>Seal String
<option value="4.html">test
<option value="5.html">test
<option value="" selected>(VIEW & ADD COOLING ACCESSORIES TO CART)
</select>
...
function GoNow0(oSel){
  var i = oSel.selectedIndex;
  var g = oSel.options[i].value;
  if (g!="") window.open(g, "_blank");
}

That will always open a new window even if a page is already open. If you want to open each file in its own new window, use this:

function GoNow0(oSel){
  var i = oSel.selectedIndex;
  var g = oSel.options[i].value;
  if (g!="") {
     var w = window.open(g, "popup"+i);
     w.focus();
  }
}

Interesting.
Tbh, maybe I've lead a sheltered life, but that's the first time I've seen markup target values used as an argument within the window.open method.
I had to quickly test it out for myself, just to be sure.

I would have expected js to treat a markup value - namely _blank - like a custom string literal (and reuse it), rather than 'understand' it and use it accordingly.

It's unlikely to make me start loving popups, but it's useful to know. So, ta.

"_blank" in window.open method is treated by javascript as any other string literal. But it also understands that markup target values such as "_blank", "_self", "_top", "_parent" or any user-defined values function the same way in window.open.

You can also set the fourth parameter of your window.open call to true or false to control whether to reuse an existing window or not.

[glenngv]

Can you point me to a reference that says window.open has 4th parameter?
The way to reuse existing popup window is by using the same user-defined target name.

window.open(url1, "popup");
window.open(url2, "popup");

Both url1 and url2 will open in the same popup window named "popup".
