Filtering Data In Json For Any Date Range

Solution 1:

Find a silder widget to your liking (there are dozens out there), and assuming your slider widget provides two date values (startDate and endDate), I would use underscore.js for something like this:

var filteredDates = _.filter(values, function(value){ 
    return (value.date_hour.getTime() > startDate.getTime() &&  
        value.date_hour.getTime() < endDate.getTime())
});
