How to stop events bubbling in jQuery?
提问by Stann
How do I stop custom event bubbling in jQuery?
如何在 jQuery 中停止自定义事件冒泡？
For example I have this code:
例如我有这个代码：
$('.myclass').bind('amodaldestroy', function(){
....does something.....
})
How do I only allow this to be triggered once on the first element it finds when bubbling? Can I just add return false?
我如何只允许在冒泡时找到的第一个元素上触发一次？我可以添加 returnfalse吗？
$('.myclass').bind('amodaldestroy', function(){
....does something.....
return false;
})

According to jQuery's documentation:
根据 jQuery 的文档：
$('myclass').bind('amodaldestroy'), function(event) {
....does something....
event.stopPropagation();
});
回答by Russ Cam
$('.myclass').bind('amodaldestroy', function(e){
e.stopPropagation();
});
You can also use return falsebut there is a subtle difference between the two in that returning false also calls event.preventDefault();
您也可以使用，return false但两者之间存在细微差别，即返回 false 也调用event.preventDefault();

For support in IE < 9:
对于 IE < 9 的支持：
$(".element").click(function(e)
{
var event = e || window.event;
event.stopPropagation ? event.stopPropagation() : (event.cancelBubble=true);
});

This might not be that great but
这可能不是那么好，但是
return false;
return falsewill do both stopPropagationand event.preventDefault...
return false将两者都做stopPropagation，并event.preventDefault...
if you want only one you can choose based on your choice
如果你只想要一个，你可以根据你的选择进行选择
please read this , this is from SO only

return falseis effectively both preventDefault and stopPropogation.
return false实际上是 preventDefault 和 stopPropogation。
preventDefaultwill prevent the default event from occuring, stopPropogation will prevent the event from bubbling up and return false will do both.
preventDefault将阻止默认事件发生，stopPropogation 将阻止事件冒泡，返回 false 将两者兼而有之。
