Check Which radiobutton is checked
(i'm beginner) i'm making an application in which the user selects 1 out of 5 radio boxes and when i click a button i get alerted which one he selects.
There are many ways to solve this, but it is difficult without additional information.
Code:
<!DOC HTML>
<html>
<head>
<title> Untitled </title>
</head>
<body>
<input type="radio" name="RBtn" value="A" onclick="alert('You selected: '+this.value)"> A
<input type="radio" name="RBtn" value="B" onclick="alert('You selected: '+this.value)"> B
<input type="radio" name="RBtn" value="C" onclick="alert('You selected: '+this.value)"> C
<input type="radio" name="RBtn" value="D" onclick="alert('You selected: '+this.value)"> D
<input type="radio" name="RBtn" value="E" onclick="alert('You selected: '+this.value)"> E
</body>
</html>
Hi! thanks for the reply. Problem is I need to use that value later in a variable. Any ideas? thanks!
Sure, save as a global variable instead of alerting the condition.

For example, here is a solution that satisfies your request.
BUT, it does not use any JS code beyond the 'alert' message.
Code:
<!DOC HTML>
<html>
<head>
<title> Untitled </title>
<script type="text/javascript">
var RBtn = false;
function showRBtnPicked() {
if (RBtn) { alert('Radio button picked: '+RBtn); }
else { alert('No radio button chosen') }
}
</script>
</head>
<body>
<input type="radio" name="RBtn" value="A" onclick="RBtn=this.value"> A
<input type="radio" name="RBtn" value="B" onclick="RBtn=this.value"> B
<input type="radio" name="RBtn" value="C" onclick="RBtn=this.value"> C
<input type="radio" name="RBtn" value="D" onclick="RBtn=this.value"> D
<input type="radio" name="RBtn" value="E" onclick="RBtn=this.value"> E
<p>
<input type="button" value="Show picked" onclick="showRBtnPicked()">
</body>
</html>
