Cannot iterate the HashMap converted as JSON String in JSP -

in spring controller: returning map values json string

map keyttlmap = getrediscachettlvalues(filterpattern);

jsonobject jsonobject = new jsonobject();

jsonobject.put("cachettlmap", keyttlmap);

return jsonobject.tostring();

in jsp ajax call:

var json = xmlhttp.responsetext;  ( var = 0; < json.cachettlmap.length; i++) {   var obj = json.cachettlmap[i];     ( var key in obj) {   name = key;   value = obj[key].tostring();   alert("name "+name +" value "+value); } } 

json string value:

{ "cachettlmap": { "product1":81213,
"product2":79936 }}

when try run jsp, json string cannot iterated.is there simple way display hashmap in ajax, kindly me this. thanks!

var json = '[{"userid" : "123123", "password": "fafafa", "age": "21"}, {"userid" :   "321321", "password" : "nana123", "age" : "34"}]';  var list = json.parse(json); var output = {};  for(var i=0; i<list.length; i++) {     for(var key in list[i])     {         if(list[i].hasownproperty(key))         {             if(typeof output[key] == 'undefined')             {                 output[key] = [];             }             output[key].push(list[i][key]);         }     } }  document.write(json.stringify(output));
