为 div 滚动 [英] onscroll for div
问题描述
div 元素是否没有 onscroll 事件处理程序?我页面上的行为似乎并未表明 div onscroll 事件处理程序被识别.
Does a div element not have an onscroll event handler?
The behaviour on my page doesn't seem to indicate the div onscroll event handler is recognized.
<div id='bd' onscroll='alert("Scroll Called");'></div>
还有，
根据 DOM 事件冒泡，div 滚动事件是否会汇总到窗口滚动事件?
Also,
Do div scroll events roll up to window scroll events, as per DOM event bubbling ?
推荐答案
根据您使用的 HTML 版本，您可以改用 onwheel 事件.
Depending on which version of HTML you're using, you could use the onwheel event, instead.
onscroll 事件仅在以下所有条件都为真时起作用:
The onscroll event works only if all the following are true:
- div有
overflow:auto、overflow:scroll、overflow-y:scroll等 - 该 div 当前有一个可以滚动的可见滚动条.
- 鼠标移动实际上会导致滚动条滚动.
所以 onscroll 事件并不真正适合检测一般的鼠标滚轮移动.
So the onscroll event is not really suited for detecting general mouse wheel movement.
请注意 onwheel 事件是 HTML 5 中的新事件.根据对 w3schools 来说，它得到了相当广泛的支持.
Please note that the onwheel event is new in HTML 5. According to w3schools, it is pretty widely supported, though.
