Json and lawnchair usage - json

Question

i saw below example in lawnchair documentation,
var store = new lawnchair({name:'testing'}, function(store) {
// create an object
var me = {key:'brian'};
// save it
store.save(me);
// access it later... yes even after a page refresh!
store.get('brian', function(me) {
console.log(me);
});
});
i am not sure i understood it correctly or not, but based on my understanding, i wrote code like this, (name,dtime,address are variables with value)
db = Lawnchair({
name : 'db'
}, function(store) {
console.log('storage open');
var formDetails = {
"candidateName" : name,
"DateTimeOfVerification" : dtime,
"ResidentialAddress" : address
}
store.save({key:"fdetails",value:formDetails});
store.get("fdetails", function(obj) {
alert(obj);
});
});
but, in alert i did not got value, i got "[object Object]".
1) how to store multi-attribute json object in lawnchair
2) how to get that json object.

Answer 1

Try this:
db = Lawnchair({name : 'db'}, function(store) {
console.log('storage open');
var formDetails = {
"candidateName" : "Viswa",
"DateTimeOfVerification" : "30/07/2012",
"ResidentialAddress" : "3 The Road, Etcc...."
}
store.save({key:"fdetails", value:formDetails});
store.get("fdetails", function(obj) {
console.log(obj);
alert(obj.value.candidateName);
alert(obj.value.DateTimeOfVerification);
alert(obj.value.ResidentialAddress)
});
});
1) You are storing the formDetails structure correctly.
2) obj.value is the collection you are looking for
Had you added the console.log(obj); line into your code and then inspected the console you could probably have worked this out for yourself.
