这些事件不能取消他们的默认动作。其他按钮不能触发按键事件。
==== Touch/Mouse Events ====
==== 触摸/鼠标事件 ====
<em>onmousedown</em>, <em>onmouseup</em> & <em>onclick</em> are all triggered by the browser. However, the <em>onmousedown</em> event doesn't trigger until you lift the stylus or you've held it on the screen for ~2 seconds—which is when text selection mode is activated—making it pretty much the same as <em>onmouseup</em>. The events cannot have their default action cancelled.
<em>onmousedown</em>, <em>onmouseup</em> & <em>onclick</em> 都是浏览器触发的事件。但是<em>onmousedown</em>事件只有你抬起手写笔，或者长按两秒以上才会发生。屏幕上的文本选择模式被激活时，这和<em>onmouseup</em>事件的效果相同。这些事件也不能取消默认动作。
<em>onmousemove</em> 和触摸、手势事件不被支持。
