一、object to json

function obj2str(o){   

            var r = [];   

            if(typeof o =="string") return "\""+o.replace(/([\'\"\\])/g,"\\$1").replace(/(\n)/g,"\\n").replace(/(\r)/g,"\\r").replace(/(\t)/g,"\\t")+"\"";   

            if(typeof o =="undefined") return "";   

            if(typeof o == "object"){   

                if(o===null) return "null";   

                else if(!o.sort){   

                    for(var i in o)   

                         r.push(i+":"+obj2str(o[i]))   

                     r="{"+r.join()+"}"  

                 }else{   

                    for(var i =0;i<o.length;i++)   

                         r.push(obj2str(o[i]))   

                     r="["+r.join()+"]"  

                 }   

                return r;   

             }   

            return o.toString();   

}

二、json to object

var jsonText="[{\"Alias\":\"張三\",\"ID\":476,\"ServicesID\":100}";

var obj= eval("(" + jsonText+ ")");
