Check Storage Used

This code sample will allow you to check how much of your allowed storage quota you are using via localStorage (maximum depends on browser).

function checkStorageUsed() {
    var dim = thisDim = 0;
    for (var x in localStorage) {
        if (x.indexOf("com.apple.") == -1) {
            thisDim = (localStorage[x].length * 2) / 1024;
            console.log(x + ' :: ' + thisDim + 'kb');
            dim += thisDim;
        }
    }
    alert(dim.toFixed(2) + 'kb');
    return dim.toFixed(2);
}

Directions:
- Call checkStorageUsed(); and you will get a popup showing the result.
