推荐答案

如果您只是想区分Enter/空格键和鼠标/指针键，我可能会同时使用onclick和onmousedown.

If you're only looking to distinguish between Enter/Space press and mouse/pointer press, I would probably go for using both an onclick and an onmousedown.

如果触发了onmousedown，我将设置一个标志，以读取onclick，告诉我这是否实际上是指针事件.

If the onmousedown is fired, I would set a flag, that I would read in the onclick, telling me whether this was actually originally a pointer event.

类似的东西:

<button onmousedown="pointerFunction()" onclick="clickFunction()">Active this</button>

<script>
var isPointerEvent = false;
function pointerFunction() {
    isPointerEvent = true;

    // Do something for pointer users
}

function clickFunction() {
    if (isPointerEvent) {
        return isPointerEvent = false;
    }

    // Do something for keyboard / screen-reader users
}
</script>
