This is my first question on stckoverflow so I hope I'm asking right.
On my website i'm using a jquery datepicker. This works fine. However, I need the following addon:
- When a user selects a date which is a specific date (var specificDate), alert with hello world.
This code already triggers the alert when selecting a date. However I am not able to figure out how to compare the "var date" with the array of specifc dates.
onSelect: function(dateText, inst){
var date = $(this).datepicker('getDate');
var specificDate = ["12-12-2013","11-12-2013"];
for (i=0; i < specificDate.length; i++){
if (date == specificDate [i]){
alert("hello world");
}
}
});
I think I need to know more about the date formats. My question is to get me a bit further with this how to make the comparison.
Thank you in advance!
Reference
if ($.datepicker.parseDate('dd-mm-yy', specificDate[0]) > $.datepicker.parseDate('dd-mm-yyyy', specificDate[1])){
alert(specificDate[0] + 'is later than ' + specificDate[1]);
}

I'm trying to come up with a simple conditional format formula for highlighting cells that have a date that is greater than three months older than today's date. It seems though that the "Date is before" option only gives a few options, none of them seem to allow what I'm looking for. Is there a custom formula that could accomplish this?
Edit: attaching a snip of the column in question:
Formula :
=DAYS(now(),B2)>90
Go to the custom formula in the conditional formating rules and use this:
=DATEDIF(A1,TODAY(),"D")<90
try:
=1*C2>DATE(YEAR(TODAY()), MONTH(TODAY())+3, DAY(TODAY()))
also make sure you have valid dates and not plain text dates. you can test this with ISDATE formula
You can use Apps Script and a Custom Menu in order to solve your issue with setting the color in the cell depending on the date. Go to Tools->Script Editor and paste this code:
function onOpen() {
var ui = SpreadsheetApp.getUi();
ui.createMenu('Custom Menu')
.addItem('Check Difference', 'dateDifference')
.addToUi();
}
function dateDifference(){
var sheet = SpreadsheetApp.getActiveSheet().getActiveRange(); // Get the selected range on the sheet
var dates = sheet.getValues(); // Get the values in the selected range
var oneDay = 1000*60*60*24;
var row = 1;
var re = /^(0?[1-9]|[12][0-9]|3[01])[\/\-](0?[1-9]|1[012])[\/\-]\d{4}$/; // This will help you to check if it's really a date
dates.forEach(function(el){ // Iterate over each value
if(typeof el[0] == 'object'){ // Check if it's really a date
var gmtZone = el[0].toString().split(" ")[4].split(":")[0]; // Take the date's GMT
var dateFormatted = Utilities.formatDate(el[0], gmtZone, "dd/MM/yyyy"); // Format the date
if(re.test(dateFormatted)){ // Test if it's the right format
// This part will calculate the difference between the current date and the future date
var futureDateMs = new Date(el[0]);
var todayDateMs = (new Date()).getTime();
var differenceInMs = futureDateMs - todayDateMs;
var differenceInDays = Math.round(differenceInMs/oneDay);
if(differenceInDays >= 91.2501){ // Test if the difference it's greater to 91.2501 days (3 motnhs)
sheet.getCell(row, 1).setBackground("#00FF00"); // Set the color to the cell
}
row++;
}
}
});
Save it by clicking on File->Save.
Then you can select a range in a column and click on Custom Menu->Check Difference as you can see in the next image:
As you can see, you will get the desired result:
Notice
It's really important to be careful with what you consider to be a "month", I mean how many days you are going to take into consideration. In my code, I took Google's suggestion of 1 = 30.4167.
Docs
These are other Docs I read to be able to help you:
Utilities.formatDate()
Working with Dates and Times.
I hope this approach can help you.
Is it possible to return a javascript date object from this? I have an text input field with the calendar and want to return a standard date object from it's value... Is this possible?
Is this what you are looking for?
var date = '2016-06-12'; // Can be document.getElementById('myField').value that points to your date field.
var date_parts = date.split('-');
var date_obj = new Date(date_parts[0],date_parts[1],date_parts[2]);
console.log(date_obj);
You can also simply use
new Date(document.getElementById('myField').value)
and see if it works. The date function is smart enough to parse based on browser's locale. This should work for time as well. Eg. new Date('2016-06-12 04:15:30')
I have a problem with Google Docs' Utilities.formatDate() function.
I have a spreadsheet that contains all of the orders we place in the lab. When an order is delivered our lab manager enters the delivery date in the relevant cell in such a spreadsheet, in the following format: dd.MM.yyyy.
I created a script that, provided certain conditions, will email whoever placed that order alerting them that the order has been delivered on that particular date. Here is the code:
function DeliveryAlerts() {
try {
var email_dict = {"Y":"Y#Z.com"}
var spreadsheet = SpreadsheetApp.openById("ABC");
SpreadsheetApp.setActiveSpreadsheet(spreadsheet);
var sheet = spreadsheet.getSheetByName("Orders");
var values = sheet.getRange("A2:Q251").getValues();
var bgcolours = sheet.getRange("A2:Q251").getBackgrounds();
for(var i=0;i<=249;i++)
{
var j = i + 2;
if (values[i][16]=="Yes" && values[i][11]!="" && bgcolours[i][16]!="#b8b8b8")
{
var email_address = email_dict[values[i][13]];
var cur_date = Utilities.formatDate(values[i][11], "GMT+1", "EEE dd.MM.yyyy");
var message = "Hello there,\n\nYour order of " + values[i][4] + " has been delivered on "+ cur_date +".\n\nBest wishes";
var subject = "Delivery alert";
MailApp.sendEmail(email_address, subject, message,{replyTo:"abc#abc.com", name:"ABC"});
sheet.getRange("Q"+j).setBackground("#b8b8b8");
}
}
} catch (err) {
MailApp.sendEmail("abc#abc.com", "Delivery Alerts Script in Order Master List", err);
}
}
I use
Utilities.formatDate(values[i][11], "GMT+1", "EEE dd.MM.yyyy") to reformat the date from, say, 25.05.2015 (that is, the value in the cell) to Mon 25.05.2015. However, what I get instead is Sun 24.05.2015.
Does anybody know what is going on?
Thank you in advance.

Check the time zone setting in the script editor. Under the FILE menu, choose PROJECT PROPERTIES in the script editor. It's possible to have a different time zone setting in Apps Script, than is in the spreadsheet. This is a common issue that arises. Apps Script allows a separate time zone setting from the spreadsheet. Also, even if the time is only off by one minute, if the time setting of the date is all zeros, it's common to get the problem that you are having. When a user enters a date, it's possible that no time setting is made. So the time is set to all zeros. The date is correct, but the time is all zeros. Even if the date was typed in at 3 in the afternoon, for example, and the date is correct, the time setting can be midnight of that day. So, even if you subtracted one second from that date, it would now be the day before.
I am creating a Todo list app in which a user will enter a date when a task is to be done and a task list which will display a list of tasks. Now what I want is the list to be displayed with the due date so if the date entered in the database is 24-07-2013 and the current date is 23-7-2013 it will display Due tomorrow. I have tried to use time-ago.js but didn't find it useful.
Here is the code which I used to create the list with date:
db.transaction(function(tx){
tx.executeSql(select_taskDetails,[],function(tx,results){
$(".taskList_view").empty();
if(results.rows.length>0){
for(var i=0;i<results.rows.length;i++){
var storedate=results.rows.item(i).set_date;
$("#datacomp").text(jQuery.timeago(storedate));
console.log("Assigned to: "+results.rows.item(i).assigned);
$(".taskList_view").append("<li class='autolist' data-filtertext='"+results.rows.item(i).taskname+"'onclick='selectname("+results.rows.item(i).id+")'><a href='#'>"+results.rows.item(i).taskname+"</a><p>"+results.rows.item(i).description+"</p><span id='datacomp'></span></li>");
temp_id=results.rows.item(i).id;
dataobj[temp_id]=results.rows.item(i).description;
}
$(".taskList_view").listview('refresh');
$('#demo_page').trigger('create');
tap_event();
}
else{
$('#demo-page').append("<h1 style='text-align:center;font-size:10px;margin-top:50px;'>No user data found<br>Please Add user <h1><a href='add_Task.html' style='text-align:center;font-size:8px;'>AddTask</a>");
}
});
});
Any suggestion will be helpful.
Thanks in advance.
I would suggest using moment.js to accomplish this -
if(results.rows.length > 0){
for (var i=0; i < results.rows.length; i++){
var storeDate = moment(results.rows.item(i).set_date, 'MM-DD-YYYY');
var currentDate = moment().format('MM-DD-YYYY')
var diff = storeDate.diff(currentDate, 'days');
}
}
Here are the moment.js docs on displaying difference
well the code I posted below all works perfectly except for a small detail. When I input today date in the field dateEntered, the later rejects it, it validates if the date entered is before todays date, validate if the date falls on a weekends, but it also show an error message when it is todays date. Actually the user should be able to enter Today or after date.
Anyone can tell me where am wrong, already tried every possible ways but still not working even the ( ==) or (===) or (<=) ..nothing
if (event.value!="")
{
var e = util.scand("ddd, dd.mmm.yy", event.value);
var a = (e.getTime()) < (new Date().getTime());
if (a) {
app.alert("The Date cannot be before Today's Date", 1);
event.rc = null;
}
if (e.getDay()==6 || e.getDay()==0) {
app.alert("Cannot take permission on a Weekend!", 2);
event.rc=null;
}
}
I found the solution to my problem, I had to set the hour to 0. Thank to the one who updated this on stackoverflow and sorry forget to retain your name.
if (event.value!="")
{
var e = util.scand("ddd, dd.mmm.yy", event.value);
var b=new Date();
b.setHours(0,0,0,0);
if (e<b) {
app.alert("ERROR: Date cannot be before"+" "+ new Date(b), 5);
event.rc = null;
}
if (e.getDay()==6 || e.getDay()==0) {
app.alert("ALERT: The date you entered ("+event.value+") falls on a WEEKEND!", 3);
event.rc=null;
}
}
This codes also contains a condition of removing one weekend from the dates since the number of leaves allowed to take ranges from 1 to 7 thus only one weekend is remove.
