如何将参数传递给作为addEventListener的参数传递或分配给事件处理程序的函数? [英] How to pass parameters to a function being passed as an argument of addEventListener or being assigned to an event handler?

问题描述

像在el.onclick = doSomething(param);

推荐答案

当您需要将参数传递给另一个函数时，可以使用匿名函数，例如:

You can use an anonymous function when you need to pass parameters to another, like this:

el.addEventListener("click", function() { doSomething(param); }, false); 

如果不需要需要参数，那么它将是:

Whereas if it didn't need parameters, it would just be:

el.addEventListener("click", doSomething, false);
