Is any way to fill an ASP variable at clientside with javascript.
I like to use that value to send as a string with a textlink like described below.
<SELECT ONCHANGE="location = this.options[this.selectedIndex].value;">
<option value="">Choose something</option>
<option value="0">------------------</option>
<option value="1">option 1</option>
<option value="2">option 2</option>
<option value="3">option 3</option>
<option value="4">option 4</option>
<option value="5">option 5</option>
<option value="6">option 6</option>
</SELECT>
Val = 'option value from the dropmenu'
a href = "testpage.asp?value=<%Response.Write(Val)%>"> Textlink </a>

hi
change last line of <a..... tag as follow
-put one id attribute there
then:
-using javascript's getElementById() function get that anchor element.
-change the attribute href using function:
element.setAttribute("href","link_str");
-link_str is the complete text link string.
using above method you can dynamically change href attribute of anchor tag

Nope, doesn't work
I use this one instead, it makes a page reload but I can live with that.
<form id=frm action=select_menu.asp method=post>
<select name=optval onchange=frm.submit()>")
<option value="">Choose something</option>
<option value="">------------------</option>
<option value="1">option 1</option>
<option value="2">option 2</option>
<option value="3">option 3</option>
<option value="4">option 4</option>
<option value="5">option 5</option>
<option value="6">option 6</option>
</select>
</form>
<a href="menu.asp?id=<%=request.form("optval")%>">Link</a>

Re: Javscript Select onchange with ASP Hi There,
I have Seen your Code and found that you are using frm.submit() function, in this function "frm" is the name of the form which you want submit, but you haven't define any name in form tag,
This Code Will Work
and you can do same thing with only using javascript:
Example:
Hope this will help you,

Thanks Kataray
Works great as long as value has been chosen.
The link (url) must be there even if no value has been set. So I'm back on square 1 again. :-)
