I need help with JS and html. I need to store <input type = "date" id = "date"> in JS var. If you try to store the date in simple var and try to print it instead of your chosen date you get printed "undefined" :
$("#printDate").click(function(){
var dateVar = ($("#date").val());
$("#results").append("<p>" + dateVar + "</p>")
});
If you try to store the date in the dateVar using new Date() you get printed "Invalid date": 
$("#printDate").click(function(){
var dateVar = new Date($("#date").val());
$("#results").append("<p>" + dateVar + "</p>")
});
Thank you for any kind of help!
