json的中换行符的处理

json作为ajax常用的一种数据类型，经常使用。但如果字段中出现换行符如何处理？

去掉显然不合适。有些字段本来就有换行符，如何能去掉？

测试一下json类的处理，也没有发现。想不到最终的处理确实如此简单：

后台代码把换行符\r\n替换为
\\r\\n，前台代码js收到的字符就是\r\n

例：将 字段值的内容为 mp3的lrc 文件中的内容 ，转换成 json 格式。

lrcc = a_lrc_content
  lrcc = replace(lrcc,"‘","\‘")
  lrcc = replace(lrcc,"\r\n","\\r\\n")

附： lrc 文件
