How to select two input fields with one radio button-CodePudding

So what am trying to do is bind two inputs fields into one radio button for users to select. The values for input fields will be generated dynamic but present for selection with a single radio button. I tried doing it bootstrap but did not work.

you should add the same name for every 2 buttons to make them work as expected.

note: id should be unique in your HTML

This solution will cause all sibling radio buttons to be selected when one is selected.

var buttons = document.querySelectorAll('.form-check-inline input:first-child');
for (var i = 0; i < buttons.length; i  ) {
    buttons[i].addEventListener('click', function() {
        // this.parent.querySelectorAll('input')
        var children = this.parentNode.getElementsByTagName('input');
        for (var j = 0; j < children.length; j  ) {
            children[j].checked = true;
        }
    });
}

.form-check-inline input[type="radio"]:not(:first-child) {
    display: none;
}
