javascript - getting the button enable or disable if the radio button is checked or unchecked

Get the solution ↓↓↓

Solution:

You can't uncheck a radio button, but if you want to do it on a checkbox, here is a suggestion using jquery:

   $("#checkBoxID").on("change", function(e) {
    $("#buttonID").prop("disabled",!$("#checkBoxID").is(":checked"));
  });
Copy code

This will set the disabled attribute on the button to the opposite of the checked attribute.

•Box Checked? Disabled Attribute on button set to false

•Box unchecked? Disabled attribute on button set to true

Updates dynamically as the checkbox is selected.
