推荐答案

如果所有你想做的是点击一个按钮，按钮元素有一个点击方法可以调用：

If all you want to do is click a button, button elements have a click method that can be invoked:

<input type="button" id="theButton" onclick="javascript:alert('The button was clicked!');" value="A button" />

<script language="javascript">

setTimeout(function(){
    document.getElementById("theButton").click();
}, 1000); // wait one second then click the button

</script>

没有必要实际模拟鼠标在特定x，y位置点击。

There's no need to "actually" simulate the mouse click at a specific x,y position.
