I want to create a form where a user select 1 item from about 10 radio buttons. Beside each radio button is a drop down box with pre-defined boxes. That's not the problem.
How do I disble drop down boxes if the radio button is not selected? Thanks.
do this
<html>
<head>
<script type="text/javascript">
function makeDisable()
{
var x=document.getElementById("mySelect")
x.disabled=true
}
function makeEnable()
{
var x=document.getElementById("mySelect")
x.disabled=false
}
</script>
</head>
<body>
<form>
<select id="mySelect">
<option>Apple</option>
<option>Banana</option>
<option>Orange</option>
</select>
<input type="radio" onclick="makeDisable()" value="Disable list">Diable<br/>
<input type="radio" onclick="makeEnable()" value="Enable list">Enable
</form>
</body>
</html>
Do like this
You can do something like this way:
first time when the page will be loaded, no radio button will be selected, so you can make dropdown's disabled by default.
and onclick event of radiobutton you can make them enabled.
Let your radio buttons have id's like rdo1,rdo2 etc..and dropdowns like ddl1,ddl2 etc..
<input id="rdo1" name="rdo" type="radio" onClick="javascript:onChange();">
<input id="rdo2" name="rdo" type="radio" onClick="javascript:onChange();">
function onChange()
{
for(i=0;i<10;i++)
{
if(eval("document.getElementById(" + ".rdo" + i + ")").checked==true)
{
eval("document.form1"+ ".ddl" + i).disabled=false;
}
}
}
will try this
Thanks. I will try this. Noticed there is no drop down in your script.
I tried
Thanks. This helps. Just a quick question...when a radio button is selected, the selection does not show, but this only enables the dropdown.
Example : Try this out
Try this out
Select an Option
<form name=form1>
Flowers<input name="radio1" type="radio" onClick="javascript:CheckMe('0','1');">
<select name=select1 disabled>
<option value="Rose">Rose</option>
<option value="Lily">Lily</option>
</select>
</br>
Colours<input name="radio1" type="radio" onClick="javascript:CheckMe('1','2');">
<select name=select2 disabled>
<option value="Red">Red</option>
<option value="Green">Green</option>
</select>
</br>
Sport<input name="radio1" type="radio" onClick="javascript:CheckMe('2','3');">
<select name=select3 disabled>
<option value="Tennis">Tennis</option>
<option value="Cricket">Cricket</option>
</select>
</br>
</form>
<script language="javascript">
function CheckMe(radName,selName)
{
var i=0;
for(i=0;i<3;i++)
{
if (eval("document.form1.radio1["+i+"].checked")==eval("document.form1.radio1["+radName+"].checked"))
{
eval("document.form1.select"+selName).disabled=false;
}
else
{
eval("document.form1.select"+(i+1)).disabled=true;
}
}
}
</script>
Perfect!
This is exactly what I want! Thanks.
