To check or select a Radio form control we use prop() method in jQuery. For that, we need to bind the prop method using a selector which can be an ID, class or value of radio control in a group.
As shown below, there is a group of Radio controls with the same name myRadio
<p>
<h5>Radio Selection</h5>
<label>
<input type="radio" name="myRadio" value="1"> Option 1
</label>
<label>
<input type="radio" name="myRadio" value="2"> Option 2
</label>
<label>
<input type="radio" name="myRadio" value="3"> Option 3
</label>
</p>
<p>
<button>Check Radio Option 2</button>
</p>
Now if we want to check second radio with value 2 we can do so using prop() method in the following way
<script>
$(function () {
$("button").click(function () {
$("input:radio[value='2']").prop('checked',true);
});
});
</script>
