Passing Listbox Text to Javascript Pop-up Window URL

Question
Is it possible to pass the contents of a textbox or Listbox into the URL portion of the javascript code window.open(URL)
? I have an asp.net listbox control that displays URL values. When ever an end user clicks on another listbox, the URL listbox provides the specific URL. I am trying to pass this URL into the above javascript code, but I do not know the correct syntax to do this. This code will execute as an onclick event.
For clarification, similar to typing “+ ListBox.Text.ToString() +”
or ‘” & List.Text & “’”
to add the content of a listbox into something else, such as a textbox. Is there specific syntax to do the same, but add the listbox.text into javascript?
Thank you,
DFM
Solution
Simply add a client-side onclick handler to your listbox as shown below:
<asp:ListBox id="ListBox1" runat="server" .....
onclick="openPopup(this)">
........
</asp:ListBox>
Then add the following javascript code:
<script type="text/javascript">
function openPopup(e){
window.open(e.value);
}
</script>
OTHER TIPS
Sure, this should be pretty easy with jQuery. Obviously the URL generation could be reduced to a single statement, but should give you the general idea.
$(document).ready(function() {
$("your-element").click(function() {
var str = $("#listbox-id").val();
var url = "your-url.com/" + str;
window.open(url);
});
});
