var json = {"total":154,"per_page":20,"current_page":1,"last_page":8,"from":1,"to":20,
"data":[{"id":1,"name":"the name","contact":"Rob"},{"id":2,"name":"the name","contact":"Joe"}]}

alert("total: " + json.total);

for(var i=0;i<json.data.length;i++) {
    var id = json.data[i]["id"];
    var name = json.data[i].name;
    var contact = json.data[i]["contact"];
    alert("id: " + id + ", name! " + name + ", contact: " + contact);
