Code example

For example, the following code is JavaScript that controls the display of the text fields ext_2 and ext_3 based on whether the multi-select checkbox set to ext_1 is checked.

{literal}
window.addEventListener('load', function() {
    // Function to control the visibility of input elements based on the state of the checkbox
    function toggleInputVisibility() {
        // Get the checkbox with id="ext_1__1"
        var checkbox1 = document.getElementById('ext_1__1');
        // Get the element with input[name="ext_2"]
        var inputText2 = document.querySelector('input[name="ext_2"]');
        if (inputText2) {
            // Check if the checkbox with id="ext_1__1" is checked
            inputText2.style.display = checkbox1.checked ? '' : 'none'; // Display if checked, otherwise hide
        }

        // Get the checkbox with id="ext_1__2"
        var checkbox2 = document.getElementById('ext_1__2');
        // Get the element with input[name="ext_3"]
        var inputText3 = document.querySelector('input[name="ext_3"]');
        if (inputText3) {
            // Check if the checkbox with id="ext_1__2" is checked
            inputText3.style.display = checkbox2.checked ? '' : 'none'; // Display if checked, otherwise hide
        }
    }

    // Execute once on page load to set the initial state
    toggleInputVisibility();

    // Set up an event listener to respond to changes in the checkbox state
    document.body.addEventListener('change', function(event) {
        // Check if the changed element is the checkbox with id="ext_1__1" or id="ext_1__2"
        if (event.target.id === 'ext_1__1' || event.target.id === 'ext_1__2') {
            toggleInputVisibility();
        }
    });
});
