如何将varible传递给一个函数到另一个函数并以纯文本形式调用函数并在纯文本中以角js显示值(how to pass the varible into one function to another function and call the fuction in plain text and show the value in the plain text in angular js)

 我在响应中获得十六进制编码值。 我已经为hexc编写代码到ascii但我不知道如何将变量传递给函数并调用函数以在纯文本中显示解码数据。出现错误 - 名称未定义

            for (var n = 0; n < hex.length; n += 2) {
                str += String.fromCharCode(parseInt(hex.substr(n, 2), 16));
