<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>

addEventListener了解一下,绑定多个事件['click','mouseover','mouseout'].forEach(function(item,index){ window.addEventListener(item, fun); })
