If the only thing you need to do is to prevent the default action, you can supply falseinstead of a function:
如果您唯一需要做的就是阻止默认操作，您可以提供false而不是函数：
$('#form').submit(false);

try return falseinstead of event.preventDefault()or accept eventas a parameter of your function.
尝试return false代替event.preventDefault()或接受event作为函数的参数。
$('#form').submit(function(event){
event.preventDefault();
});
Not sure why some people think this no longer works but here is an example showing it does still work.
不知道为什么有些人认为这不再有效，但这里有一个例子表明它仍然有效。

Comment out the event handler and it will alert.
注释掉事件处理程序，它会发出警报。
Regarding stopPropagation()and stopImmediatePropagation()they don't prevent the form from submitting at all. They just prevent the event from bubbling up the dom.
关于stopPropagation()并且stopImmediatePropagation()他们根本不阻止表单提交。他们只是防止事件冒泡 dom。

Other way is:
另一种方式是：
$('#form').submit(function(){
//some code here
return false;
});

I wasn't able to get the posted answers to work, and only supplying false was not an option for me. I found this to work:
我无法获得已发布的答案，并且仅提供 false 对我来说不是一个选择。我发现这有效：
$(document).on('submit', '#form', function(event){
event.preventDefault();
});
