禁止浏览器缓存js

方法：在js文件后加上数学随机数;

Math.random()

比如：源代码为

<script src="./js/lib/require/require.js" data-main="./js/modules/main/main"></script>

修改之后变成：

<script>
        document.write('<script src="./js/lib/require/require.js"' + ' data-main="./js/modules/main/main.js?rnd=' + Math.random() + """ + '></script>');
</script>
