i trying fetch data not getting lke below

   function servicesucceeded(result)       {          if (datatype == "json")         {            var obj =  jquery.parsejson(json.stringify(json.stringify(result)));            (var x = 0; x < obj.length; x++)              {              }          }      } 

in obj.length count of characters coming , jquery.parsejson(result) not working

please help

if result json there no need parse in way. jquery.ajax return javascript object if datatype set json.

so in servicesucceeded function may operate on result variable directly. if trying iterate on bed types change loop this:

for (var = 0; < result.getbedtypelist1result.length; i++) {   // ...do stuff   // var bed = result.getbedtypelist1result[i]] }
