JS对象序列化成json数据和json数据转化为JS对象的代码

JS对象序列化成json数据：

rush:js;"> function Serialize(obj){ switch(obj.constructor){ case Object: var str = "{"; for(var o in obj){ str += o + ":" + Serialize(obj[o]) +","; } if(str.substr(str.length-1) == ",") str = str.substr(0,str.length -1); return str + "}"; break; case Array: var str = "["; for(var o in obj){ str += Serialize(obj[o]) +","; } if(str.substr(str.length-1) == ",") str = str.substr(0,str.length -1); return str + "]"; break; case Boolean: return "\"" + obj.toString() + "\""; break; case Date: return "\"" + obj.toString() + "\""; break; case Function: break; case Number: return "\"" + obj.toString() + "\""; break; case String: return "\"" + obj.toString() + "\""; break; } } var staff_list_obj ={}; var staff_id = 1001; staff_list_obj[staff_id] = {}; staff_list_obj[staff_id]["姓名"] = '111'; staff_list_obj[staff_id]["测试"] = '222'; alert(Serialize(staff_list_obj));

JS对象序列化为JSON对象的方法二

rush:js;"> var $ = $ || {};

/**

• 将JS对象序列化为JSON字符串
• @param {Mixed} o The variable to decode
• @return {String} The JSON string
• String json = $.encode(o);
  */
  $.encode = (function() {
  if ( typeof(JSON)!=='undefined' && typeof(JSON.stringify)!=='undefined') {
  return JSON.stringify;
  }
  var I = !!{}.hasOwnProperty,_ = function(I) {
  return I < 10 ? "0" + I : I;
  },A = {
  "\b" : "\b","\t" : "\t","\n" : "\n","\f" : "\f","\r" : "\r","\"" : "\\"","\" : "\\"
  };
  return (function(C) {
  if (typeof C == "undefined" || C === null) {
  return "null";
  } else {
  if (Object.prototype.toString.call(C) === "[object Array]") {
  var B = ["["],G,E,D = C.length,F;
  for (E = 0; E < D; E += 1) {
  F = C[E];
  switch (typeof F) {
  case "undefined" :
  case "function" :
  case "unkNown" :
  break;
  default :
  if (G) {
  B.push(",");
  }
  B.push(F === null ? "null" : $.encode(F));
  G = true;
  }
  }
  B.push("]");
  return B.join("");
  } else {
  if ((Object.prototype.toString.call(C) === "[object Date]")) {
  return "\"" + C.getFullYear() + "-" + (C.getMonth() + 1) + "-" + (C.getDate()) + "T" + (C.getHours()) + ":" + (C.getMinutes()) + ":" + (C.getSeconds()) + "\"";
  } else {
  if (typeof C == "string") {
  return "\"" + C.replace(/([\x00-\x1f\"])/g,function(B,) {
  var I = A[_];
  if (I) {
  return I;
  }
  return '';
  }).replace(/[^\u0000-\u00FF]/g,function($0) {
  return escape($0).replace(/(%u)(\w{4})/gi,"\u$2")
  }) + "\"";
  } else {
  if (typeof C == "number") {
  return isFinite(C) ? String(C) : "null";
  } else {
  if (typeof C == "boolean") {
  return String(C);
  } else {
  B = ["{"],F;
  for (E in C) {
  if (!I || C.hasOwnProperty(E)) {
  F = C[E];
  if (F === null) {
  continue;
  }
  switch (typeof F) {
  case "undefined" :
  case "function" :
  case "unkNown" :
  break;
  default :
  if (G) {
  B.push(",");
  }
  B.push($.encode(E),":",$.encode(F));
  G = true;
  }
  }
  }
  B.push("}");
  return B.join("");
  }
  }
  }
  }
  }
  }
  });
  })();

json数据转化为JS对象：

rush:js;"> var jsonString={....}/[....]; eval("var obj="+jsonString); alert(obj);

写道

rush:js;"> function evalJSON(json){ var obj = null; try { obj = eval("(" + json + ")"); } catch(E){}

return obj ;
}
