In stead of parsing JSON you can do like followng    ajax          dataType   json     using json  jquery will make parse for  you      To access a property of your JSON do following  data 0  name   data 0  address    Why you need data 0  because data is an array  so to its content retrieve you need data 0   first element   which gives you an object   quot name quot   quot myName quot    quot address quot    quot myAddress quot     And to access property of an object rule is  Object property  or sometimes Object  quot property quot      in some case  So you need data 0  name and so on to get what you want   If you not set dataType  json then you need to parse them using   parseJSON   and to retrieve data like above

You should do  alert data 0  name     Take the property name of the first array   and not   alert data myName    jQuery should be able to sniff the dataType for you even if you don t set it so no need for JSON parse   fiddle here  http   jsfiddle net H2yN6
