Adding a popup function to dropdown menu

[akulion]

1) Script Title: Drop down menu w/ description

2) Script URL (on DD): http://www.dynamicdrive.com/dynamici...bodescribe.htm

3) Describe problem: Is there any way for me to use the selection list to launch a sized popup window? Basicaly what I need is to have each menu item to be launched in a popup window of a different size when the user selects it and presses GO

I can do this for normal links using the popup generator (on DHTML) but I also need this for the dropdown list since it greatly reduces the size of bigger listed menus.

Thanks,
Aku

Sure, try the below modified script, which lets you optionally specify the pop up window's size when using target="newwin" to get it to open in a new window:

<!--Example drop down menu 1-->

<form name="form1">
<select name="select1" size="1" style="background-color:#FFFFD7" onChange="displaydesc(document.form1.select1, thetext1, 'textcontainer1')">
<option selected value="http://www.javascriptkit.com">JavaScript Kit </option>
<option value="http://freewarejava.com">Freewarejava.com</option>
<option value="http://wired.com" target="newwin">Wired News</option>
<option value="http://www.news.com" target="newwin" class="500 by 600">News.com</option>
<option value="http://www.codingforums.com" target="newwin">Coding Forums</option>
</select>
 <input type="button" value="Go" 
onClick="jumptolink(document.form1.select1)"><br>
<span id="textcontainer1" align="left" style="font:italic 13px Arial">
</span>
</form>

<!--Example drop down menu 2-->

<form name="form2">
<select name="select2" size="1" style="background-color:#E3FFDF" onChange="displaydesc(document.form2.select2, thetext2, 'textcontainer2')">
<option selected value="http://www.cnn.com">CNN</option>
<option value="http://www.msnbc.com">MSNBC</option>
<option value="http://news.bbc.co.uk">BBC News</option>
<option value="http://www.theregister.com/">The Register</option>
</select>
 <input type="button" value="Go" 
onClick="jumptolink(document.form2.select2)"><br>
<span id="textcontainer2" align="left" style="font:italic 13px Arial">
</span>
</form>



<!--IMPORTANT: Below script should always follow all of your HTML codes above, and never proceed them-->
<!--To be safe, just add below script at the end of your page-->

<script type="text/javascript">

/***********************************************
* Drop down menu w/ description- &#169; Dynamic Drive (www.dynamicdrive.com)
* This notice must stay intact for use
* Visit http://www.dynamicdrive.com/ for full source code
***********************************************/

//1) CUSTOMIZE TEXT DESCRIPTIONS FOR LINKS ABOVE
var thetext1=new Array()
thetext1[0]="Comprehensive JavaScript tutorials and over 400+ free scripts"
thetext1[1]="Direct link to hundreds of free Java applets online!"
thetext1[2]="Up to date news on the technology front"
thetext1[3]="News.com- The #1 technology News site."
thetext1[4]="Web Coding and development forums"

/// You may define additional text arrays if you have multiple drop downs:
var thetext2=new Array()
thetext2[0]="CNN- US and World News."
thetext2[1]="MSNBC- NBC News online."
thetext2[2]="BBC News- Updated every minute of every day."
thetext2[3]="TheRegister- Daily IT news."

// Now, see 2) below for final customization step

function displaydesc(which, descriptionarray, container){
if (document.getElementById)
document.getElementById(container).innerHTML=descriptionarray[which.selectedIndex]
}

function jumptolink(what){
var selectedopt=what.options[what.selectedIndex]
if (document.getElementById && selectedopt.getAttribute("target")=="newwin"){
if (selectedopt.className!="")
window.open(selectedopt.value, "", "width="+parseInt(selectedopt.className.split("by")[0])+",height="+parseInt(selectedopt.className.split("by")[1]))
else
window.open(selectedopt.value)
}
else
window.location=selectedopt.value
}

//2) Call function displaydesc() for each drop down menu you have on the page
//   This function displays the initial description for the selected menu item
//   displaydesc(name of select menu, name of corresponding text array, ID of SPAN container tag):
//   Important: Remove the calls not in use (ie: 2nd line below if there's only 1 menu on your page)

displaydesc(document.form1.select1, thetext1, 'textcontainer1')
displaydesc(document.form2.select2, thetext2, 'textcontainer2')

</script>

I tried using the Code and it indeed opens a New window, But it does not size the window accordingly.

Any ideas of how I can get the window to size to my specifications?


Thank you,
