推荐答案

您必须使用event.stopPropagation()停止将事件传播到父树.

You have to use event.stopPropagation() that stop the event propagation to the parent tree.

尝试 FIDDLE ，

由于您尚未提供$ get实现，因此我已将代码编码为如下所示的模拟功能

As you have not provide the $get implementation, i have coded as a mock function like below

  function $get(idselector) {
    alert('$get');
    return $('#' + idselector);
  }

  function ABCDEF(event, object) {
    alert('ABCDEF');
    event.stopPropagation(); // try commenting this will reproduce your issue
  }

希望它对您有用
