Add an event listener to the change event on the checkbox.

<input type="text" id="inputID" value="abc" readonly></input>
<input type="checkbox" id="myCheck" >
<script>
    var checkbox = document.getElementById('myCheck');
    checkbox.addEventListener('change', function() {
        document.getElementById('inputID').readOnly = !this.checked; 
    });
