To determine if the checkbox is checked, utilize the checkbox's “checked” property. The checked property outputs a boolean value true if it is checked; else, it gives false. For the verification, you can use two different procedures; one is the onclick() event, and the other is addEventListener() method.

This is a technique that allows you to control certain styles depending on whether checkboxes (or radio buttons) are checked or not. You might typically see the checkbox hack used for toggling visibility of tabs, dropdown menus, and so on.

Use the below lines of code in a JavaScript file: function checkClickFunc() { var checkbox = document. getElementById('agree'); ... document. getElementById("agree"). onclick = function checkClickFunc() { alert("Checkbox is clicked"); ... document. getElementById("agree"). addEventListener("click", checkClickFunc);

Checkbox event handling using pure Javascript There are two events that you can attach to the checkbox to be fired once the checkbox value has been changed they are the onclick and the onchange events.

Use the onclick event Whenever we click on any element, the onclick event triggers that particular element. We can also use the onclick event with a checkbox. So, whenever the user checks or unchecks the checkbox, we can invoke any function using the onclick event attribute.

Whenever the user checks or uncheck any checkbox, it invokes the handleChage() function. In the handleChange() function, we check if the checkbox is checked and add the checkbox value to the allChecked array. If the checkbox is unchecked, we remove the checkbox value from the allChecked array.

Use check mark to refer to a mark placed next to an item to show it's selected. Use checkbox, not box or check box, to refer to a checkbox in UI. Avoid talking about UI elements. Instead, discuss what the customer needs to do or what they're looking at.

When used in conjunction with checkboxes, the onchange event function can be set up to detect when a checkbox has been checked or unchecked. An event listener is used to attach the onchange event to the checkbox element, and a callback function is invoked when the event is triggered.
