click() 被使用在支援的元素(例如任一 <input> 元素),便會觸發該元素的點擊事件。事件會冒泡至 document tree(或 event chain)的上層元素,並觸發它們的點擊事件。其中的例外是:click() 方法不會讓 <a> 元素和接收到真實滑鼠點擊一樣進行頁面跳轉。

[1] Prior to Gecko 5.0 (Firefox 5.0 / Thunderbird 5.0 / SeaMonkey 2.2), Gecko would not implement the click() method on other elements that might be expected to respond to mouse clicks, such as links (<a> elements), nor would it necessarily fire the click event of other elements.

[2] In Presto-based versions of Opera, the click() method will be silently ignored if made on an <input> with its type attribute set to file and its CSS display property set to none.

[3] Older versions had, and only.
