本文实例讲述了Javascript中For In语句用法。分享给大家供大家参考。具体如下：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 | <html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>For In 语句</title>
<script type="text/javascript">
function Student(name, age) {
this.name = name;
this.age = age;
}
var stu = new Student("内马尔", 20);
for (var s in stu) {
alert(s + ":" + stu[s]);
}
var myArr = [1, 3, 5, 7, 9];
for (var i in myArr) {
alert(i + ":" + myArr[i]);
}
</script>
</head>
<body>
