HTMLElement.click()

The HTMLElement.click() method simulates a mouse click on an element.

When click() is used with supported elements (such as an <input>), it fires the element's click event. This event then bubbles up to elements higher in the document tree (or event chain) and fires their click events.

click()

<form>
  <input type="checkbox" id="myCheck" onmouseover="myFunction()" onclick="alert('click event occurred')">
</form>

// On mouse-over, execute myFunction
function myFunction() {
  document.getElementById("myCheck").click();
}
