javascript - 如何将参数传递给addEventListener侦听器函数？(How to pass arguments to addEventListener listener function?)

Question

The situation is somewhat like-(情况有点像-)

var someVar = some_other_function(); someObj.addEventListener("click", function(){ some_function(someVar); }, false); The problem is that the value of someVar is not visible inside the listener function of the addEventListener , where it is probably being treated as a new variable.(问题在于someVar的值在addEventListener的侦听器函数中不可见，在其中它可能被视为新变量。)   ask by Abhishek Yadav translate from so

Answer 1

Why not just get the arguments from the target attribute of the event?(为什么不仅仅从事件的target属性获取参数？)

Example:(例：) var someInput = document.querySelector('input'); someInput.addEventListener('click', myFunc, false); someInput.myParam = 'This is my parameter'; function myFunc(evt) { window.alert(evt.currentTarget.myParam); } JavaScript is a prototype-oriented language, remember!(JavaScript是一种面向原型的语言，请记住！)
