Is there any way to implement such an event modifier or function in VUE

Business background

  • when submitting data on the page
  • often involves preventing repeated clicks
  • is usually handled in the corresponding click event method
  • but it has to be written in every method, which is really troublesome

wishful thinking

  • vue contains a series of modifiers such as once,self
  • can control events
  • is it possible to implement a similar function on your own
  • add delay and the like
    • to the end of the event.
  • then this click event can only take effect once in 300ms?

question

  • may not be an event modifier
  • simply put, this effect can be achieved by adding an attribute or something to the tag.

vue does not have such an event modifier, but it is possible to implement such a modifier, but it is not expected to encapsulate such a modifier, because this idea is anti-shake and throttling, and it exists. If you don't know about it, you can go and have a look at it on the Internet.

the principle of anti-shake and throttling is to use timers to control the execution of code. Your problem can be solved like this: 

function handClick(){
    if(handClick.timeout){
        return false
    }else{
        handClick.timeout = setTimeout(function(){
            handClick.timeout = undefined
        },300)
    }
    
    //
}
