var a = {"list":[ 
{

"item_alias_list":"mouse",
"eancode":"19",
}
,   {

"item_alias_list":"aets",
"eancode":"11",
}
,   {

"item_alias_list":"infor",
"eancode":"23",
}
]};

// get "mouse"
var ret = a.list[0].item_alias_list;

Remove the comma after the number strings for valid JSON

comma does not affect any thing

maybe not for this operation... but can cause problems in cases where you need a VALID JSON object

you can try this

suppose

var Data =

 {"list":[{"item_alias_list":"mouse","eancode":"19"},
      {"item_alias_list":"aets","eancode":"11"},
      {"item_alias_list":"infor","eancode":"23"}]
 };

var len = Data.list.length;
for(var i = 0; i<len; i++)
{
     for(var key in Data.list[i])
     {
           alert(key +"="+ Data.list[i][key])
     }
}
