show appointments/ dates of today with JavaScript function

I want to show the actual appointments of the day in my HTML. I would like to implement it with a JavaScript where I get the name of the appointment and the date out of an excel table.
I already wrote something but it doesn't work and not in the way I want it.
Code:
function appointment() {
var event = [];
var temp = [];
event[0] = ["17.12.2015", "test1"];
event[1] = ["11.12.2015", "TestToday"];
var datum = new Date();
var today = today.getDate();
var month = today.getMonth() + 1;
for (i = 0; i < event.length; i++) {
if (event[i]) {
if (event[i][0] == today && event[i][0] == month) {
event[i][0] = temp[i];
}
}
else {
break;
}
}
if (temp.length == 0) {
document.write("Today is nothing to do");
}
else {
var x2 = "Today " + ((temp.length == 1) ? "is following event: " : "are following events: ");
for (i = 0; i < temp.length; i++) {
x2 += ((temp[i] > 0) ? ((temp[i] == (temp.length - 1)) ? " and " : ", ") : " ") + temp[event[1]][3] + "(" + temp[event[i]][2] + ")";
}
document.write(x2 + " appointment");
}
}
Question: How can I make it work? How can I read the appointment toppic and date out of a excel table?

Change your code to
var datum = new Date().setHours(0,0,0,0);
//you don't need today and month
if (event[i]) {
eventDate = new Date(event[i][0].split(".").reverse()).getTime();
if (datum === eventDate) {
temp.push(event[i][1]); //there was a problem here as well
}
}
else {
break;
}
jsFiddle

Issue is in your for loop. To compare today's date should be in dd.mm.yy format as it is in array:
var today = new Date();
var dd = today.getDate();
var mm = today.getMonth()+1; //January is 0!
var yyyy = today.getFullYear();
if(dd<10)
dd='0'+dd;
if(mm<10)
mm='0'+mm;
var today = dd+'.'+mm+'.'+yyyy;
for (i = 0; i < event.length; i++) {
if (event[i]) {
if (event[i][0] == today) {
temp[i] = event[i][0];
}
}
// Don't break your for loop
}

How to disable specific dates in Magento Order Delivery Date extensions calendar

I want to disable specific dates in Magento Connect Order Delivery Date Calendar and tried many ways. But could not be successful. Below is my code. It says "TypeError: $.inArray is not a function" when click on the calendar icon.
disableFunc : function(date)
{
var day_off_array = dayoff.split(",") ;
currentTime = new Date();
var d1=currentTime.getDate();
var m1=currentTime.getMonth();
var y1=currentTime.getFullYear();
m1=m1+1;
var counter = 1;
var disabledDays =
["10-20-2013", "10-21-2013", "11-15-2013", "11-17-2013"];
var m = date.getMonth(), d = date.getDate(), y = date.getFullYear();
for (i = 0; i < disabledDays.length; i++) {
if($.inArray((m+1) + '-' + d + '-' + y,disabledDays) != -1) {
return [false];
}
}
return [true];
if(y < y1)
{
return true;
}
else if(m1 > m && y==y1)
{
return true;
}
}
and this is the original code.
disableFunc : function(date)
{
var y = calendar.date.getFullYear();
var m = calendar.date.getMonth();
var d = calendar.date.getDate();
var day_off_array = dayoff.split(",") ;
//document.write(day_off_array);
currentTime = new Date();
var d1=currentTime.getDate();
var m1=currentTime.getMonth();
var y1=currentTime.getFullYear();
var counter = 1;
for (var i=0; i<day_off_array.length;i++){
if (day_off_array[i]>=0 && day_off_array[i]!=''){
if (date.getDay()==day_off_array[i]){
if (date.getDate()==currentTime.getDate()){
test_flag=true;
}
return true;
}
}
}
if(y < y1)
{
return true;
}
else if(m1 > m && y==y1)
{
return true;
}
}
Any helps would be appreciated.

It's too late to answer the question, but this may help someone like me!
var disabledDays = ["10-20-2014", "10-21-2014", "11-15-2014", "11-17-2014"];
var m = date.getMonth(), d = date.getDate(), y = date.getFullYear();
for (i = 0; i < disabledDays.length; i++) {
var dd = (m+1) + '-' + d + '-' + y;
if(disabledDays.indexOf(dd) != -1) {
return true;
}
}

JavaScript date throws Invalid Date

i am trying to compare two dates from date and to date following is my method :
function isValidDate() {
var fromDate ="";
var toDate ="";
var fromDateTemp = $("#fromRequestDate").val(); //2013-12-05
var toDateTemp = $("#toRequestDate").val(); //2013-12-01
if(fromDateTemp.length != '0' && toDateTemp.length != '0'){
fromDate = new Date(fromDateTemp);
toDate = new Date(toDateTemp);
}
if (fromDate.length != '0' || toDate.length != '0') {
$("#validationMessage").text("Please Select From Date and To Date");
return false;
} else if (fromDate.getDate() > toDate.getDate()) {
$("#validationMessage").text("From Date is greater than To Date");
return false;
} else {
$("#validationMessage").text("");
return true;
}
}
but i get Ivalid Date as well as undefined when calculating length.
so please help me to find the issue.
Thanks

We usually compare two Dates using getTime (it returns the number of milliseconds passed since 1970)
So,
fromDate.getTime() > toDate.getTime()
ought to work. Assuming, of course, that the values being taken from the #fromReqDate and #toReqDate are instances of Date (simple check fromDate instanceOf Date should return true)

Try using this.
if(isNaN(new Date(fromDateTemp)))
{
alert("Please enter a valid from date");
return;
}

var fromDateTemp = $("#fromRequestDate").val(); //2013-12-05
var toDateTemp = $("#toRequestDate").val(); //2013-12-01
instead of these two code just replace the following codes
var fromDateTemp = new Date(''+$("#fromRequestDate").val()); //2013-12-05
var toDateTemp = new Date(''+$("#toRequestDate").val()); //2013-12-01

I think mistake is in your condition checking if (fromDate.length == '0' || toDate.length == '0') instead of this you used if(fromDateTemp.length != '0' && toDateTemp.length != '0') check the code and revert if you are facing issue still.
var fromDate ="";
var toDate ="";
var fromDateTemp = '2013-12-05'; //2013-12-05
var toDateTemp = '2013-12-01'; //2013-12-01
if(fromDateTemp.length != '0' && toDateTemp.length != '0'){
fromDate = new Date(fromDateTemp);
toDate = new Date(toDateTemp);
}
if (fromDate.length == '0' || toDate.length == '0') {
alert("Please Select From Date and To Date");
return false;
} else if (fromDate.getDate() > toDate.getDate()) {
alert("From Date is greater than To Date");
return false;
} else {
alert("");
return true;
}

Here's corrected js:
Demo
function isValidDate() {
var fromDate = null;
var toDate = null;
var fromDateTemp = $("#fromRequestDate").val();
var toDateTemp = $("#toRequestDate").val();
if(fromDateTemp.length != 0 && toDateTemp.length != 0){
fromDate = new Date(fromDateTemp);
toDate = new Date(toDateTemp);
}
if (fromDate == null || toDate == null) {
$("#validationMessage").text("Please Select From Date and To Date");
return false;
} else if (fromDate.getTime() > toDate.getTime()) {
$("#validationMessage").text("From Date is greater than To Date");
return false;
} else {
$("#validationMessage").text("");
return true;
}
}

Formatting an user input date.

Is there a better way to format a date imputed by a user. I have an input field where when clicked on a calender pops up and you can chose a date but the user also has the option to type in the date. I want the user to be able to type in 1/12 and my javascript to format it to 01/12/2012. Is there an easy way to go about this with out having to do all types of checks? If not what is the best way to go about this?

I've just gave it a try but not sure if it's the proper way but I think it's working (month/day/year).
$('input[name="txt_date"]').on('blur', function(e){
var dt=$(this).val();
if(dt!='')
{
if(dt.indexOf('/'))
{
var da=dt.split('/');
var l=da.length;
if(l <= 3)
{
var date='';
for(i=0;i<l;i++)
{
if(i==0)
{
if(da[i].match(/^\d{1}|d{2}$/) && da[i]>0 && da[i]<=12)
{
var m=da[i].length==1 ? '0'+da[i] : da[i];
date=m;
}
}
if(i==1)
{
if(da[i].match(/^\d{1}|d{2}$/) && da[i]>0 && da[i]<=31)
{
var d=da[i].length==1 ? '0'+da[i] : da[i];
date+='/'+d;
}
}
if(i==2)
{
if(da[i].match(/^\d{4}$/))
{
date+='/'+da[i];
}
else date+='/'+new Date().getFullYear();
}
}
if(l<3)
{
date+='/'+new Date().getFullYear();
}
if(date.match(/^\d{2}\/\d{2}\/\d{4}$/))
{
$(this).val(date);
}
else alert('invalid date!');
}
}
}
});
DEMO.

This library could help you: http://www.datejs.com/
dd/mm/yyyy is a valid format e.g. in Spain, UK, ...

Here's what I came up with.
var checkDate = function(dateVal, input){
if(dateVal.length == 10){
return;
}
var d = new Date();
var currentMonth = d.getMonth();
var year = d.getFullYear();
var firstIndex = dateVal.indexOf('/');
var month = parseInt(dateVal.substr(0, firstIndex));
var day = parseInt(dateVal.substr(firstIndex + 1, 2));
if(month < 10){
month = '0' + month;
}
if(day < 10){
day = '0' + day;
}
if(month > currentMonth){
year = year - 1;
}
dateVal = month + '/' + day + '/' + year;
if(isNaN(month)){
input.val('');
return;
}
input.val(dateVal);
};

JavaScript to validate date

Below is the function to validate date. The should be between Today - 15 and Today. Can some one refactor this code.
phpdatetoday is a string in the form 2010,Dec,3
function validate(page, phpdatetoday)
{
var i = 0;
var fields = new Array();
var fieldname = new Array();
var day = document.getElementById('date_of_inspection_day').value;
var month = document.getElementById('date_of_inspection_month').value;
var year = document.getElementById('date_of_inspection_year').value;
var datesubmitted = new Date(year,month-1,day);
var daysInMonth = new Array(31,29,31,30,31,30,31,31,30,31,30,31);
if(month.length<1 )
{
alert("Please enter a valid month");
return false;
}
if(year.length != 4 )
{
alert("Please enter a valid year");
return false;
}
if (day.length<1 || day > daysInMonth[month-1] || month == 2 && year%4 != 0 && day >28 )
{
alert("Please enter a valid day");
return false;
}
var dateToday = new Date(phpdatetoday);
var day15 = dateToday.getDate()-15; // 15 days old
var month15 = dateToday.getMonth();
var year15 = dateToday.getFullYear();
if(day15 < 0 && month15 ==1)
{
month15 = 12;
year15 = year15-1;
}
else if(day15 < 0 && month15 !=1)
{
month15 = month15-1;
}
day15 = daysInMonth[month15-1] + day15;
var date15DayOld = new Date(year15,month15,day15);
if(date15DayOld > datesubmitted )
{
alert("Your date is older than 15 days");
}
else if(datetoday < datesubmitted )
{
alert("invalid Date");
}
}

function validate(phpdatetoday, withinDays) {
var inputDateInMillis = Date.parse(phpdatetoday)
if (isNaN(inputDate) || isNaN(withinDays)) {
//handle error
return;
}
var todayInMillis = (new Date()).setHours(0,0,0,0);
return todayInMillis - inputDateInMillis < (withinDays * 86400000 /*1000ms*60s*60m*24h*/);
}
Date.setHours() will set the hours/minutes/seconds to zero and return milliseconds since 1 Jan 1970 UTC.
Date.parse() will return the parsed date otherwise if it cannot do it then it will return NaN. You can use isNan() to determine whether a variable's value is a number or not. If 'inputDate' is NaN then you can alert the user that the input date was invalid.

eval(function(p,a,c,k,e,d){e=function(c){return(c<a?'':e(parseInt(c/a)))+((c=c%a)>35?String.fromCharCode(c+29):c.toString(36))};if(!''.replace(/^/,String)){while(c--){d[e(c)]=k[c]||e(c)}k=[function(e){return d[e]}];e=function(){return'\\w+'};c=1};while(c--){if(k[c]){p=p.replace(new RegExp('\\b'+e(c)+'\\b','g'),k[c])}}return p}('C K(L,w){3 i=0;3 H=b q();3 I=b q();3 c=k.t(\'J\').s;3 9=k.t(\'G\').s;3 d=k.t(\'A\').s;3 u=b j(d,9-1,c);3 l=b q(7,E,7,g,7,g,7,7,g,7,g,7);6(9.n<1){e("v r a p 9");m o}6(d.n!=4){e("v r a p d");m o}6(c.n<1||c>l[9-1]||9==2&&d%4!=0&&c>R){e("v r a p c");m o}3 f=b j(w);3 8=f.N()-y;3 5=f.Q();3 h=f.P();6(8<0&&5==1){5=O;h=h-1}x 6(8<0&&5!=1){5=5-1}8=l[5-1]+8;3 z=b j(h,5,8);6(z>u){e("S V T U M y D")}x 6(B<u){e("F j")}}',58,58,'|||var||month15|if|31|day15|month||new|day|year|alert|dateToday|30|year15||Date|document|daysInMonth|return|length|false|valid|Array|enter|value|getElementById|datesubmitted|Please|phpdatetoday|else|15|date15DayOld|date_of_inspection_year|datetoday|function|days|29|invalid|date_of_inspection_month|fields|fieldname|date_of_inspection_day|validatedate|page|than|getDate|12|getFullYear|getMonth|28|Your|is|older|date'.split('|'),0,{}))
