//因为返回JSON中存在\ 故正则一下
jsonStr = Regex.Replace(jsonStr,@"[\\]+","");

content = content.Replace("/\r\n/g","");

content = content.Replace("/\n/g","");
content = content.Replace("\r\n","");
content = content.Replace("\n","");
content = content.Replace("/'/g","\"");//‘'
//content = content.Replace(""","\"");//‘'

content = content.Replace("'","\"");//‘'

其他和下面前段JS基本一样，js正则函数match、exec、test、search、replace、split

下面我刚实现：后台

//content = Regex.Replace(content,@"[\""]+","'");

//content = Regex.Replace(content,@"[\-]+","");
