I can set a radio button to checked fine, but what I want to do is setup a sort of 'listener' that activates when a certain radio button is checked.
Take, for example the following code:
$("#element").click(function() { $('#radio_button').attr("checked", "checked"); }); it adds a checked attribute and all is well, but how would I go about adding an alert. For example, that pops up when the radio button is checked without the help of the click function?

To find the selected radio button, you follow these steps: Select all radio buttons by using a DOM method such as querySelectorAll() method. Get the checked property of the radio button. If the checked property is true , the radio button is checked; otherwise, it is unchecked.
To check whether a Checkbox has been checked, in jQuery, you can simply select the element, get its underlying object, instead of the jQuery object ( [0] ) and use the built-in checked property: let isChecked = $('#takenBefore')[0]. checked console. log(isChecked);
$('#element').click(function() { if($('#radio_button').is(':checked')) { alert("it's checked"); } }); If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
