JS 字符串简单加密

//加密
function encryptionCode(str){ 
   var len=str.length; 
   var rs=""; 
   for(var i=0;i<len;i++){ 
          var k=str.substring(i,i+1); 
          rs+= (i==0?"":",")+str.charCodeAt(i); 
   } 
   return rs; 
} 
//解密
function unEncryptionCode(str){ 
   var k=str.split(","); 
   var rs=""; 
   for(var i=0;i<k.length;i++){ 
      rs+=String.fromCharCode(k[i]); 
   } 
   return rs; 
}
