//编写JS代码
function aaa() {
var rrr = document.getElementById("rrr");
var mmm = document.getElementById("rrr").innerHTML;
var bbb = confirm("系好安全带,准备启航--目标JS");
if (bbb === true){
rrr.innerHTML = ("出发喽");
} else if (bbb === true && mmm == ("出发喽")){
mmm = ("再出发喽");
} else if (bbb === true && mmm == ("再出发喽")){
mmm = ("再出发喽");
}
else {

各位小伙伴！ 我自己解决了！ 可是有没有更好的方法呢？
function aaa() {
var rrr = document.getElementById("rrr");
var bbb = confirm("系好安全带,准备启航--目标JS");
if (bbb === true){
var mmm = document.getElementById("rrr").innerHTML;
if (mmm === ""){rrr.innerHTML = ("出发喽");}
else if(mmm === "出发喽") {rrr.innerHTML = ("再出发喽");}
else if(mmm === "再出发喽") {rrr.innerHTML = ("再出发喽");}
else if(mmm === "不出发") {rrr.innerHTML = ("出发喽");}
} else if (bbb === false){
rrr.innerHTML = ("不出发");
}
}
html代码如下
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>系好安全带,准备启航</title>
<!--引入外部文件的方式-->
<script type="text/script" src="script.js"></script>
</head>
<body>
<input name="button" type="button" onClick="aaa()" value="点击我" />
<p id="rrr"><p/>
</body>
</html>
