return false from within a jQuery event handler is effectively the same as calling both e.preventDefault and e.stopPropagation on the passed jQuery.Event object.
e.preventDefault() will prevent the default event from occuring, e.stopPropagation() will prevent the event from bubbling up and return false will do both. Note that this behaviour differs from normal (non-jQuery) event handlers, in which, notably, return false does not stop the event from bubbling up.
综上所述，return false 并不能完美的执行 取消默认动作的指令，经过测试，jquery的function 中，IE 8 用return false 是不行的，比如submit 表单，会提交2此，但是在firefox，chrome，IE9 中都是可行的。
"Each person's life is like a book; some people prefer to savor it slowly, while others like to gradually forget it. Looking back, I want to see if I can discern the trajectory of the world from my seemingly insignificant life. I am a child from the countryside, and perhaps most people cannot understand what my so-called countryside looks like. Indeed, the impressions of the countryside can be very different depending on the country, and moreover, more than 40 years have passed, during these 40 years of rapid development in China. A phrase suddenly comes to mind, 'I see him building tall buildings, I see him feasting, I see everything collapsing.' The place where I was born is a small town in the southwest of China, a town so small that it only has one street, and the widest part is only 3 meters. Paved with stone slabs, worn by many years of use, the slabs are not flat but rather filled with small bumps and hollows, yet strangely smooth. At the end of the street is a ...
