Question

Assume I get a table element with ID=”emTab”, how do I call JS to click it?

Thanks.

Answer 1

document.getElementById(“emTab”).onclick = function() {
// your code goes here
};

See element.onclick

To trigger click event

document.getElementById("emTab").click();

See element.click

The click method is intended to be
used with INPUT elements of type
button, checkbox, radio, reset or
submit. Gecko does not implement the
click method on other elements that
might be expected to respond to
mouse–clicks such as links (A
elements), nor will it necessarily
fire the click event of other
elements.

Non–Gecko DOMs may behave differently.

When a click is used with elements
that support it (e.g. one of the INPUT
types listed above), it also fires the
element’s click event which will
bubble up to elements higher up the
document tree (or event chain) and
fire their click events too. However,
bubbling of a click event will not
cause an A element to initiate
navigation as if a real mouse-click
had been received.

Cross browser way

If you can use jQuery then it would be

$("#emTab").trigger("click");
