想給test設置多個事件，默認是onclick,如果傳參，可以傳事件類型，eventType，比如onmouseover,等等，怎么實現，搞了很久還沒搞好，麻煩大家幫忙解答一下，謝謝啊<!DOCTYPE html><html><head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>Document</title></head><body> <div id="test"> a </div> <script> var a = 0; var test = document.getElementById("test"); var eventType = onmouseover || onclick; test.onclick = function () { a++; console.log(a); a % 2 == 0 ? test.innerHTML = "a" : test.innerHTML = "b"; } </script></body></html>
