If variable is not set, then get throws an error instead of returning null or undefined about store.js HOT 4 CLOSED

Hi @irfancue, I added a test in 3ab2df0 and do not see the issue you're talking about in Chrome 24.0.1312. Can you do some more investigation?

Hi Marcus,

I have different issues:

This works
store.set("user", {id :"1", name: "Joe"});
No problem getting
var userName = store.get("user").name;
console.log(userName); //prints Joe

But when I do not "set" before "get" Javascript throws an error

        var testA = store.get("IHaveNotBeenSetBefore");         
        console.log(testA); // ERROR instead of "undefined"

And if want to change just one value I have first to get the element, then add a new key and then set it again:

                var user = store.get("user");
                user.birthdays = response.birthdays.count //NEW key birthdays
                store.set("user", user);

If I do it like

store.set("user", {name: "Joe", id:1});
store.set("user", {birthdays: response.birthdays.count};

all other keys (name, id) are deleted.

Is there a workaround?

What browser are you on? Can you please create a standalone HTML page which replicated your first issue and upload that?

Regarding your second issue, store.js merely serializes and deserializes for you, but you can easily write a function to do what you need. E.g

function addProperties(key, properties) {
store.set(key, jQuery.merge(store.get(key) || {}), properties))
}

Hi @irfancue,

If you're still seeing an issue please fork and create a failing test in test.html (http://marcuswestin.github.com/store.js/test.html).
