jQuery:同一事件的多个处理程序

如果我将两个事件处理程序绑定到同一个元素的同一个事件会发生什么?

例如:

var elem = $("...")elem.click(...);elem.click(...);

最后一个处理程序获胜"，还是两个处理程序都运行?

解决方案

两个处理程序都会运行，jQuery 事件模型允许一个元素上有多个处理程序，因此后面的处理程序不会覆盖旧的处理程序.

处理程序将按照它们被绑定的顺序执行..p>

What happens if I bind two event handlers to the same event for the same element?

For example:

var elem = $("...")
elem.click(...);
elem.click(...);

Does the last handler "win", or will both handlers be run?

解决方案

Both handlers will run, the jQuery event model allows multiple handlers on one element, therefore a later handler does not override an older handler.

The handlers will execute in the order in which they were bound.
