How to check radio button is checked using JQuery?
jQuery 3.3.1
if (typeof $("input[name='yourRadioName']:checked").val() === "undefined") {
alert('is not selected');
}else{
alert('is selected');
}
//the following code checks if your radio button having name like 'yourRadioName'
//is checked or not
$(document).ready(function() {
if($("input:radio[name='yourRadioName']").is(":checked")) {
//its checked
}
});
Given a group of radio buttons:
<input type="radio" id="radio1" name="radioGroup" value="1">
<input type="radio" id="radio2" name="radioGroup" value="2">
You can test whether a specific one is checked using jQuery as follows:
if ($("#radio1").prop("checked")) {
// do something
}
// OR
if ($("#radio1").is(":checked")) {
// do something
}
// OR if you don't have ids set you can go by group name and value
// (basically you need a selector that lets you specify the particular input)
if ($("input[name='radioGroup'][value='1']").prop("checked"))
You can get the value of the currently checked one in the group as follows:
$("input[name='radioGroup']:checked").val()
