How can I know which radio button is selected via jQuery?
I have two radio buttons and want to post the value of the selected one. How can I get the value with jQuery?
I can get all of them like this:
$("form :radio")
How do I know which one is selected?
Answer:
To get the value of the selected
radioName item of a form with id myForm:$('input[name=radioName]:checked', '#myForm').val()
Here's an example:
$('#myForm input').on('change', function() {
alert($('input[name=radioName]:checked', '#myForm').val());
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form id="myForm">
<input type="radio" name="radioName" value="1" /> 1 <br />
<input type="radio" name="radioName" value="2" /> 2 <br />
<input type="radio" name="radioName" value="3" /> 3 <br />
</form>
