1. i have json file @ /path/to/json containing:

   {"a": {"s": [{"l": "ppp"}]}} 

   i'm using jquery expression:

   $.ajax({    url: '/path/to/json',    datatype: 'json',    async: false,    success: function(data) {        $.each(data.a.s, function(index,element) {            lines=element.l;               })    } });

   this file. how assign contents of file variable search within json object who's 'l' attribute 'ppp' retrieve object's 'qqq' value?

you can use array index, if know index of item fetched

to first item in s array

data.a.s[0].l 

to second item in s array

data.a.s[1].l 

or use loop

for(var i= 0; i<data.a.s.length; i++){     lines = data.a.s[i].l }
