<!DOCTYPE html>

<body>
<button id="abc" onclick="temp1()">button</button>
<script type="text/javascript">
function temp1() {
alert("temp1");
};
function temp2() {
alert("temp2");
}
document.getElementById("abc").addEventListener("click", temp2, false);
</script>
</body>
</html>，但我想先显示" temp2"，然后显示" temp1"
可能吗？或事件执行顺序取决于浏览器，因此我无法更改它？
感谢您的帮助！
请查看此：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Close window</title>
</head>
<body>
<!-- here is your first AddEventlistener-->
<button id="abc" onclick="temp1()">button</button>
<script type="text/javascript">
function temp1() {
alert("temp1");
};
function temp2() {
alert("temp2");
}
/*then here is your second AddEventlistener*/
var d = document.getElementById("abc");
d.addEventListener("click", temp2, false);
/*javascript will execute it in order
if you want to change the order. remove first EventListener then register new one after. something like this:
*/
//remove listener
d.onclick = null;
//register new
d.addEventListener('click', temp1);
</script>
</body>
</html>有几种方法可以保证此处的顺序：
document.getElementById("abc").addEvenListener("click", function() {
temp2();
temp1();
}, false);
另一个选择是：
function temp2() {
alert();
temp1(); // call temp1 at the end of temp2
}
document.getElementById("abc").addEventListener("click", temp2, false);
