JS加密解密第二版
今天是2015-11-21 星期六，在家里没啥事，又把前面的加密解密函数进行了整理，发出来，方便以后使用，上次的主要偏向于功能方面，这次偏向于应用方面，下面看给出代码以及我的使用说明。

使用说明：
本程序主要是由eval去执行代码，使用前期准备的JS代码段要求符合eval的使用规范以及注意事项，不懂的可以参考我博客前面几期的相关文章说明。
本次演示使用简单的根据当前日期算第几周程序，是随便找我以前的一个blogs文章中的程序：当前是本月第几周，程序代码如下：
var getMonthWeek = function(a, b, c) { var date = new Date(a, parseInt(b) - 1, c), w = date.getDay(), d = date.getDate(); return Math.ceil((d + 6 - w) / 7); //① }; var getYearWeek = function(a, b, c) { var date1 = new Date(a, parseInt(b) - 1, c), //② date2 = new Date(a, 0, 1), d = Math.round((date1.valueOf() - date2.valueOf()) / 86400000); //③ return Math.ceil((d + ((date2.getDay() + 1) - 1)) / 7); }; today = new Date(); var y = today.getYear(); var m = today.getMonth() + 1; var d = today.getDate(); document.write("今天是"+ m + "月的第 " + getMonthWeek(y, m, d) + " 周"); //④ document.write("<br /><br />"+today.getHours()+":"+ today.getMinutes()+":"+ today.getSeconds());
程序很简单，大家应该都能看懂，我就不解释了，主要是加密其中的①②③④语句，下面具体说说加密使用的步骤：
1：把需要加密的JS代码段整理出来，如果是函数或多条语句，最好是每个单独执行的代码段压缩下，整理成每行是一个执行单元的语句。
这样的好处是一：方便后续的执行，二：大大减少加密后的代码。
由于我也把解密函数进行加密，所以预留了两行（后面会用到）。
Math.ceil((d + 6 - w) / 7); new Date(a, parseInt(b) - 1, c) Math.round((date1.valueOf() - date2.valueOf()) / 86400000); "今天是"+ m+ "月的第 "+ getMonthWeek(y, m, d)+ " 周" alert('aaa'); alert("bbb");
2：整理好的代码段放入“JS原代码段”的输入框中，按“加密”按钮，生成加密后的代码数字。生成后的代码数组如下：

6：把程序中需要替换的①②③④语句替换成解密语句DecodeJS(pw,0)并执行解密代码，参考如下：
//return Math.ceil((d + 6 - w) / 7); //① return eval(DecodeJS(pw,0)); //document.write("今天是"+ m + "月的第 " + getMonthWeek(y, m, d) + " 周"); //④ document.write(eval(DecodeJS(pw,3)));
好了，再次运行你的程序，完美执行。
另外，有什么需要注意说明，我后续也会补上来。
注意：
1：在JS原代码段的输入框中，进来不要有空格行和回车行等空行，因为空行也会参与加密代码的运算中。
2：生成解密函数的加密代码可以单独使用，或放到前面生成的加密代码段数组中，前提是加密代码段数组中必须提前要有占位行，如我上面的替换代码。
