I want to detect the when the ‘yes’ radio button is chosen with JavaScript.

  • 0

I want to detect the when the ‘yes’ radio button is chosen with JavaScript. This is a small lightweight form and does not have jQuery or other library installed. My goal is for it to work in most major browsers and be written in just a few lines of code.

   <script type="text/javascript">
        if(document.forms[0].test.buy){alert("Clicked yes.);
   </script> 

</head>
<body>
    <form name="test">
        Buy Ice cream?
        <input type="radio" name="buy" value="yes" /> Yes
        <input type="radio" name="buy" value="no" /> No<br />
    </form>
</body>

    Your radio button needs to handle the onClick event – 

    <input type="radio" name="buy" value="male" onClick="myYesFunc()" />Yes

    then you’ll need a javascript function to handle the event

    function myYesFunc()
{
  alert ("Yes Clicked");
}
