asp_web_howto thread: Controlling Appearance of <SELECT> tags


Message #1 by raymurphy@g... on Wed, 17 Oct 2001 15:31:08
Folks,



I'm currently developing a couple of asp applications which are coming 

along nicely, but have to incorporate a number of amendments to another 

application - and would like some advice on how to implement one specific 

amendment.



I need to add a radio button to a search page, with that radio button 

denoting whether Date of Birth should be added to the search criteria - 

the idea is that if the user clicks the radio button, they would then be 

presented with a dropdown list of Year values. 



Ideally, I'd like the Year dropdown to be invisible to the user UNLESS 

they have clicked on the radio button, in which case they should see the 

Year dropdown. Has anyone ideas on how to implement such a feature, 

please ?



Thanks.



Ray

sure do...

for a small fee... J/K ;-)



do something like this. I didn't test it, but it should work...

--------------------------------------

<script language="javascript">

function makeVisible(x){

	if(x==1){

	hideme.style.visibility='visible'

	}else{

	hideme.style.visibility='hidden'

	}

}

</script>





<input type="radio" id="radDate" name="radDate" onclick="makeVisible(1)"

/>Unhide

<input type="radio" id="radDate" name="radDate" onclick="makeVisible(2)"

/>Hide

<div id="hideme" style="visibility:hidden">my hidden stuff</div>
