Check if localStorage is available

Question

I know there has been many questions about checking for localStorage but what if someone manually shuts it off in their browser? Here\'s the code I\'m using to

Answer 1

With this function you can check if localstorage is available or not, and you keep under control the possible exceptions.

function isLocalStorageAvailable() {

    try {
        var valueToStore = 'test';
        var mykey = 'key';
        localStorage.setItem(mykey, valueToStore);
        var recoveredValue = localStorage.getItem(mykey);
        localStorage.removeItem(mykey);

        return recoveredValue === valueToStore;
    } catch(e) {
        return false;
    }
}
