JS对象序列化成json数据：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 | 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)); |

json数据转化为JS对象：
1 2 3 | var jsonString={....}/[....]; eval("var obj="+jsonString); alert(obj); |
写道
1 2 3 4 5 6 7 8 | function evalJSON(json){ var obj = null; try { obj = eval("(" + json + ")"); } catch(E){} return obj ; } |
