You can use the jQuery :checked selector together with the each() method to retrieve the values of all checkboxes selected during a group. The each() method used here simply iterates over all the checkboxes that are checked. Let’s try an example to check how it works:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>how to get checked checkbox value using jquery</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script>
$(document).ready(function() {
$("button").click(function(){
var favorite = [];
$.each($("input[name='sport']:checked"), function(){
favorite.push($(this).val());
});
alert("My favourite sports are: " + favorite.join(", "));
});
});
</script>
</head>
<body>
<form>
<h3>Select your favorite sports:</h3>
<label><input type="checkbox" value="football" name="sport"> Football</label>
<label><input type="checkbox" value="baseball" name="sport"> Baseball</label>
<label><input type="checkbox" value="cricket" name="sport"> Cricket</label>
<label><input type="checkbox" value="boxing" name="sport"> Boxing</label>
<label><input type="checkbox" value="racing" name="sport"> Racing</label>
<label><input type="checkbox" value="swimming" name="sport"> Swimming</label>
<br>
<button type="button">Submit</button>
</form>
</body>
</html>
