var str=" <%=str %>";;
刚刚做测试时，这句代码这里多加了一个分号。

var str=" <%=str %>";;
多个分号没不会影响什么
看看你运行的时候是不是出现了乱码

变更和字符串中间要用+连起来, 不是变更就不要分开这么写59行
var str="epass授权记录="Default?menuid=01003"&数据修改记录="Default?menuid=01001""; 改成这样
var str="epass授权记录=Default?menuid=01003&数据修改记录=Default?menuid=01001";
不过还会有别的提示,慢慢改吧

调试易

为什么会提示缺少“；”？
