javascript对字符串进行html编码

转载地址: http://www.cnblogs.com/mingda/archive/2010/01/29/htmlencode_and_htmldecode_for_javascript.html

编码函数：

function htmlEncode(str) { var s = ""; if (str.length == 0) return ""; s = str.replace(/&/g, "&"); s = s.replace(/</g, "<"); s = s.replace(/>/g, ">");   s = s.replace(/\'/g, "'"); s = s.replace(/\"/g, """); return s;}

解码函数:

function htmlDecode(str){   var s = "";   if (str.length == 0) return "";s = str.replace(/&/g, "&");s = s.replace(/</g, "<");s = s.replace(/>/g, ">"); s = s.replace(/'/g, "\'");   s = s.replace(/"/g, "\""); return s;   }
