jQuery:事件发生的顺序

In a nutshell

With all the variations to consider when applying effects, it can become difficult

to remember whether the effects will occur simultaneously or sequentially. A brief

Effects on a single set of elements are:

• Simultaneous when applied as multiple properties in a single

.animate()method

• Queued when applied in a chain of methods, unless the queueoption

• Queued when applied within the callback of another effect or within the

callback of the .queue()metho
