Answer 2

You can use the jQuery prop() method to check or uncheck a checkbox dynamically such as on click of button or an hyperlink etc.

$("#radio1").prop("checked", true);

To check the current state of the checkbox you must instead use the jQuery checked property . It is dynamically updated as the user checks/unchecks.

if(document.getElementById('radio1').checked) {
alert("Checked");
}
