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
}
