(一)数组或对象中最会一个属性是否该加逗号的测试

1、结论:在IE8中有兼容问题、会将逗号后面的空也算作一个属性,所以最后一个属性末不要加逗号

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Document</title>
</head>
<body>
</body>
<script src="libs/jquery-1.8.3.min.js"></script>
<script type="text/javascript">
    $(function(){

        var data = [
            {
                "aHref" : "javascript:;void(0)",
                "imgSrc": "img/swiper01.jpg",
            },{
                "aHref" : "javascript:;void(0)",
                "imgSrc": "img/swiper02.jpg",
            },{
                "aHref" : "javascript:;void(0)",
                "imgSrc": "img/swiper03.jpg",
            },{
                "aHref" : "javascript:;void(0)",
                "imgSrc": "img/swiper04.jpg",
            },{
                "aHref" : "javascript:;void(0)",
                "imgSrc": "img/swiper05.jpg",
            },
        ];
        console.log(data.length)
        // 1. chrome:5
        // 2. firefox:5
        // 3. IE:6
        // 哈哈这个真的注意,建议不管数组还是对象中,最后一个元素不要加逗号
    });
</script>
</html>
