有没有一种方法来获取所有default_event_actions，然后使用jQuery中的event.preventDefault（）阻止除某些对象之外的其他对象？

Question

I'd like to know if is there a way to have a list of the default_event_actions for a particular element that ' event.preventDefault() ' has been applied on and tell the script what event or action to prevent or not...

something like:

$(element).on('click', function(e){

e.preventDefault() //this will prevent all

//...is there a way of preventing specifically or particularly... 
}) 

Is it possible?

Answer 1

You can use e.type to check type of event and based on condition can prevent default for example:

$(element).on('click', function(e){
    if(e.type == 'click')
        e.preventDefault(); //this will prevent all
    }
});

Answer 2

You can use jQuery event namespaces to give unique name to your events : event.namespace

And to find all events attached to a particular element, you can look at Jonathan Sampson's answer for this question (Can I find events bound on an element with jQuery?)
