e.preventDefault();有什么区别?并返回假? [英] What's the difference between e.preventDefault(); and return false?

问题描述

$("a.avatar").click(function(e){
      e.preventDefault();
      $("#thumbnails").fadeIn();
    });

和

$("a.avatar").click(function(e){
      $("#thumbnails").fadeIn();
          return false;
    });

对于我来说，两者都可以实现相同的目标.

Both can achieve the same goal for me.

推荐答案

从jQuery事件处理程序返回false是 e.preventDefault 和 e.stopPropagation .

Returning false from jQuery event handlers is equivalent to calling both, e.preventDefault and e.stopPropagation.

所以区别在于，preventDefault仅将阻止发生默认事件操作，即，在单击链接，提交表单等页面重定向时，return false还将停止

So the difference is that preventDefault will only prevent the default event action to occur, i.e. a page redirect on a link click, a form submission, etc. and return false will also stop the event flow.
