Using Input Radio checked property: The Input Radio checked property is used to return the checked status of an Input Radio Button. Use document. getElementById('id'). checked method to check whether the element with selected id is check or not.
To set the default checked value of a radio button in React: Store the radio button value in the state. Initialize the state to the value of the default checked radio button. Set the checked property on each radio button conditionally, e.g. checked={selected === 'yes'} .
"CheckedChanged" event is activated when a radiobutton is selected.
You can use document.getElementsByName(<button_name>) or document.getElementsByTagName("input") to get an array of input elements. Loop through those elements to check which is checked.
Here is an example of how to get the value of the checked button from a set of radio buttons with the name "selected":
<html>
<head>
<script type="text/javascript">
function get_radio_value() {
var inputs = document.getElementsByName("selected");
for (var i = 0; i < inputs.length; i++) {
if (inputs[i].checked) {
return inputs[i].value;
}
}
}
function onSubmit() {
var id = get_radio_value();
alert("selected input is: " + id);
}
</script>
</head>
<body>
<form onsubmit="onSubmit();">
<input name="selected" value="1" type="radio"/>1<br/>
<input name="selected" value="2" type="radio"/>2<br/>
<input name="selected" value="3" type="radio"/>3<br/>
<input type="submit" value="submit"/>
</form>
</body>
</html>
I choose let number of code for a required function. The one worked for me is given below from api.jquery.com. Hope this helps others.
HTML
<input type="radio" name="option" value="o1">option1</input>
<input type="radio" name="option" value="o2">option2</input>
JavaScript
var selectedOption = $("input:radio[name=option]:checked").val()
The variable selectedOption will contain the value of the selected radio button (i.e) o1 or o2
