How to undo event.stopPropagation in jQuery?
提问by Hubro
I'm using event.stopPropagation()in my application. There has appeared, however, one scenario where I want the propagation to continue as if the aforementioned function was never called. So I'm wondering; is there a way to "resume" propagation after it's been stopped? It would be terribly tedious to move the one call to event.stopPropagationto a dozen separate conditional statements.
我event.stopPropagation()在我的应用程序中使用。但是，出现了一种情况，我希望传播继续进行，就好像上述函数从未被调用过一样。所以我想知道; 有没有办法在停止传播后“恢复”传播？将一个调用移动event.stopPropagation到十几个单独的条件语句将是非常乏味的。

Once propagation has been stopped, it cannot be resumed. As a workaround, what you can do is set a variable, and then only stop if this variable is true:
传播一旦停止，就无法恢复。作为一种解决方法，您可以做的是设置一个变量，然后仅在该变量为真时停止：
var stop = false;
// do your logic here
if(stop){
event.stopPropagation();
}

Put the event.stopPropagation()call inside your condition. For example
把event.stopPropagation()电话放在你的条件中。例如
$el.click(function(event) {
if (some_condition) {
event.stopPropagation()
// do stuff
}
else {
// do other stuff, without stopping propagation
}
});
Tedious it may be, but unfortunately stopPropagation is a one way switch. Once stopped, you can't turn it back on for the same event.
它可能很乏味，但不幸的是 stopPropagation 是一种单向切换。一旦停止，您将无法为同一事件重新打开它。

Just refactor your original event like this:
只需像这样重构您的原始事件：
var refEvent = event.originalEvent;
refEvent.cancelBubble = false;
refEvent.defaultPrevented = false;
refEvent.returnValue = true;
refEvent.timeStamp = (new Date()).getTime();
if (event.target.dispatchEvent){
event.target.dispatchEvent(refEvent);
} else if (event.target.fireEvent) {
event.target.fireEvent(refEvent);
}

Here is a solution that works:
这是一个有效的解决方案：
$('#mydiv').on('click.new', function(e){
e.stopImmediatePropagation();
alert('this will happen only once');
$('#mydiv').unbind('click.new');
});
It makes use of the fact that event can have custom namespace, and can unbind accordingly. It also works for e.stopPropagation. For that matter, it can undo anything associated with that custom click event.
它利用了事件可以具有自定义命名空间的事实，并且可以相应地解除绑定。它也适用于e.stopPropagation. 就此而言，它可以撤消与该自定义点击事件相关的任何内容。
