The onclick property of the GlobalEventHandlers mixin is the EventHandler for processing click events on a given element.

The click event is raised when the user clicks on an element. It fires after the mousedown and mouseup events, in that order.

Note: When using the click event to trigger an action, also consider adding this same action to the keydown event, to allow the use of that same action by people who don't use a mouse or a touch screen.

Syntax

target.onclick = functionRef;

Value

functionRef is a function name or a function expression. The function receives a MouseEvent object as its sole argument. Within the function, this will be the element upon which the event was triggered.

Only one onclick handler can be assigned to an object at a time. You may prefer to use the EventTarget.addEventListener() method instead, since it's more flexible.

Example

This example logs the position of clicks.

HTML

<p>Click anywhere in this example.</p>
<p id="log"></p>

JavaScript

let log = document.getElementById('log');

document.onclick = inputChange;

function inputChange(e) {
  log.textContent = `Position: (${e.clientX}, ${e.clientY})`;
}
