I have an array of unavailable dates set at unavailableDates and weekends.
Array:
<script type="text/javascript">//<![CDATA[
var unavailableDates = [];
{foreach $fixed.rows as $row}
var row = {};
row['date_from'] = "{$row.fixed_date_from.value}";
row['date_until'] = "{$row.fixed_date_until.value}";
row['name'] = "{$row.fixed_name.value} ({$row.fixed_type.value})";
unavailableDates.push(row);
{/foreach}
//]]></script>
Q1) How can I add an extra check for the until date. I have got it working as shown below for the from date?
Q2) Can I improve the code to use in_array instead of loop through each of the dates for each calendar day?
var days = ["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"];
var unavailableDays = ["Saturday","Sunday"];
$("#.datePicker").datepicker($.extend(true, {}, $.initDatePickers.defaults, {
beforeShowDay: function(date) {
ymd = date.getFullYear() + "-" + ("0"+(date.getMonth()+1)).slice(-2) + "-" + ("0"+date.getDate()).slice(-2);
day = new Date(ymd).getDay();
result = null;
// Check if date in unavailable array or weekend
for(var i = 0; i < unavailableDates.length; i++){
if ((ymd == unavailableDates[i].date_from) && $.inArray(days[day], unavailableDays) < 0) {
return [false,"unavailable",unavailableDates[i].name];
}
}
if(result){
return result;
} else {
return [true, "available", ""];
}
}
}));
Use the befreShowDay option to parse your data array to determine if day is selectable or not
beforeShowDayType: Function( Date date )
A function takes a date as a parameter and must return an array with [0] equal to true/false indicating whether or not this date is selectable, 1 equal to a CSS class name or "" for the default presentation, and [2] an optional popup tooltip for this date. It is called for each day in the datepicker before it is displayed.

I want to disable days dynamically by using array,
replacing the code :
var monday = 1;
var tuesday = 2;
with a dynamic value from a database
var disabledDay = ["1","2","3"];
Any help will really be appreciated Thanks
old code
jsFiddle: http://jsfiddle.net/314wd8t7/
$("#picker").datepicker(
{ beforeShowDay: function(day) {
var string = jQuery.datepicker.formatDate('yy-mm-dd', day);
var day = day.getDay();
var monday = 1;
var tuesday = 2;
if (day != monday && day != tuesday){
return [ true ]
} else {
return [ false ]
}
}
});
$('#picker').datepicker();
<div id="picker"></div>
I think you want something like this.
http://jsfiddle.net/dgo48jry/
const disabledDays = ["1", "2", "3"]
.map((n) => parseInt(n))
.filter((n) => !isNaN(n));
$("#picker").datepicker({
beforeShowDay: function(day) {
return [!disabledDays.includes(day.getDay())];
}
});
$('#picker').datepicker();
This assumes that your server is returning the values as strings. If you dont need string, you can simply remove the map filter lines.
I have the 2 columns in my table schema:
Column D= Date, i.e. 20180611 [yyymmdd]
Column F= Continuous Value, i.e. 0.1, 0.6, -0.3 etc.
This is what I want to happen:
Check in column D for yesterday's date. Then, take in the corresponding row, and check if column F is greater than 0.5 (for yesterday's date). If TRUE, then send an email alert.
This is the script I have but it does not trigger for some reason. What is wrong with it?
function readCell() {
var sheet = SpreadsheetApp.getActive().getSheetByName('test');
var dates = sheet.getRange('D1:D').getValues();
var date = null;
var dateRow = 0;
var dateCount = dates.length;
var yesterday = new Date();
yesterday.setDate(yesterday.getDate() - 1);
var yesterdayString = yesterday.toDateString();
for (dateRow; dateRow < dateCount; ++dateCount) {
try {
date = dates[dateRow].toDateString();
if (date === yesterdayString) {
++dateRow;
// To account for zero-based array
break;
}
} catch (error) {
Logger.log(error);
}
}
var value = sheet.getRange('F' + dateRow).getValue();
if (value >= 0.5) {
var result = ('Alert found on: ' + date);
MailApp.sendEmail('blabla#gmail.com', 'Alert', result);
}
};
Here is the data
The problem could be due to the use of an open reference D2:D to get values and then use dates.length to set the number of iterations on the for loop because it could be a number too large.
One "quick and dirty" way that could solve the above issue is to replace
var dateCount = dates.length;
by
var dateCount = sheet.getDataRange().getValues().length;
I know its a bit silly question, but I actually wanted to know how can I retrieve the year value for a date that I already have without using the "Split" function. I can achieve it with the help of the "split" function. Below is the code that I used in jquery.
outputJSon = JSON.parse($('#' + Datepicker_id).val());
var currentYear = parseInt(CalculateYearfromString($('#' + currentActivityCalendarId).parents('.service-timeline').find('.membership-year .period').text()));
if (currentYear === undefined && $.trim(currentYear) === "")
currentYear = new Date().getFullYear();
if (parseInt(outputJSon["Date"].split('/')[0]) === currentYear)
outputDate = outputJSon["Date"];
else
outputDate = outputJSon["Date"].replace(outputJSon["Date"].split('/')[0], currentYear)
outputDateType = outputJSon["DateType"];
In the above code, I am retrieving the date value in a JSON format which returns Date eg. 2016/05/26 and DateType eg. Day.
I am fetching the current year that I have selected and then checking if currentYear value is equal to the year that I have in the outputJSon["Date"]. If there is a match, then I am replacing the [0] value of the outputJSon["Date"] with the currentYear, with the help of replace function. This works as expected and no error is encountered.
I just want to be sure that if the date format changes(from 2016/05/26 to 26/05/2016)**then the split function that I have written will retrieve wrong value. How can I avoid this. Shall I remove **split function and think of something else?
Any help is appreciated.
Thanks,
Totally unsexy, but what's wrong with indexOf?
if (outputJSon["Date"].indexOf(currentYear) != -1) {
// currentYear is in the string somewhere
}
Note also that in the original, there is no need for parseInt:
outputJSon["Date"].split('/')[0] == currentYear
is sufficient (and less to type).
Also, parseInt will never return undefined, so:
currentYear === undefined
will always be false and so:
if (currentYear === undefined && $.trim(currentYear) === "")
will never be true and the assignment:
currentYear = new Date().getFullYear();
will never execute.
I would also seriously question the use of:
outputJSon = JSON.parse($('#' + Datepicker_id).val());
The use of JSON.parse seems entirely gratuitous, you already have a string returned by $('#' + Datepicker_id).val().
You can check the length to make sure it is a valid year number.
currentYear2 = outputJSon["Date"].split('/');
currentYear2 = (currentYear2[0].length === 4) ? currentYear2[0] : currentYear2[2];
Is there any issues when you simply do
outputDate = new Date(outputJSon["Date"]).getFullYear();
You can try something like this:
JSFiddle.
Code
function getYear() {
var input = $("#dpDate").val();
var cdate = getDate(input);
console.log(cdate, cdate.getFullYear());
}
function getDate(input) {
var arr = [];
var seperator = ['/', '-'];
var year, month, date;
var yearIndex = 2;
var result = undefined;
seperator.forEach(function(s) {
if (input.indexOf(s) > -1)
arr = input.split(s);
});
if (arr.length > 1) {
// Set year
if (arr[0] > 1000) {
year = arr[0]
yearIndex = 0;
} else if (arr[2] > 1000) {
year = arr[2];
yearIndex = 2;
}
// set month and date
// If string starts with year, assume yyyy/mm/dd
if (yearIndex === 0) {
month = arr[1]
date = arr[2]
} else {
// If value greater than 12, assume it as date and other one as month
if (arr[0] > 12) {
date = arr[0]
month = arr[1]
} else if (arr[1] > 12) {
date = arr[1]
month = arr[0]
}
// If none of the value is ggreater than 12, assume default format of dd/mm/yyyy
else {
date = arr[0]
month = arr[1]
}
}
result = new Date(year, month - 1, date);
}
return result;
}

if (parseInt(outputJSon["Date"].split('/')[yearIndex]) === currentYear) {

I have an array look like:
var v = ["07/27/2015", "07/28/2015", "08/29/2015", "08/29/2015", "07/27/2016"]
What I want to do is sort this dynamically into a new empty array nv. When the sorting is done nv should look like.
var nv = [["07/27/2015", "07/28/2015"], ["08/29/2015", "08/29/2015"], ["07/27/2016"]]
Is it possible to sort like this way?
var dates = ["07/27/2015", "07/28/2015", "08/29/2015", "08/29/2015", "07/27/2016"];
var groupedDates = dates.reduce(function(l, r) {
var keyParts = r.split("/"),
key = keyParts[2] + keyParts[0];
if (typeof l[key] === "undefined") {
l[key] = [];
}
l[key].push(r);
return l;
}, {});
var result = Object.keys(groupedDates)
.sort(function(a, b) { return Number(a) - Number(b); })
.map(function(key) {
return groupedDates[key];
});
console.log(result); // [["07/27/2015","07/28/2015"],["08/29/2015","08/29/2015"],["07/27/2016"]]

So I made a function that puts the dates into an object whose properties are month and year. A date is put into the property of its month and year. The function then creates an array and creates an inner array for every property of the function. In each inner array it puts all the dates of that property. I figured this approach would be more efficient than nested for loops.
// function takes an array of dates in the following format MM/DD/YYYY
// outputs an array with inner arrays of dates. Each inner array contains dates of the same month and year
var groupDates = function(dateArray) {
// create object to organize dates by month and year
var dateHash = {};
// the array that is outputted
var groupedDates = [];
//for every date in dateArray
dateArray.forEach(function(currentDate) {
// check if any other dates with the same month and year exist in the dateHash object
if (dateHash[currentDate.substr(0, 2) + currentDate.substr(6)]) {
// if other dates exist, push the date to the array in the dateHash property for the dates current month and year
dateHash[currentDate.substr(0, 2) + currentDate.substr(6)].push(currentDate);
} else {
// otherwise create a property for the dates month and year and store the current date in an array in the propery
dateHash[currentDate.substr(0, 2) + currentDate.substr(6)] = [currentDate];
}
});
// for every propery in the datehash, push the array of dates into the grouped dates array
for (var dateGroup in dateHash) {
groupedDates.push(dateHash[dateGroup]);
}
return groupedDates;
};
var dateArray = ["07/27/2015", "07/28/2015", "08/29/2015", "08/29/2015", "07/27/2016"];
console.log(groupDates(dateArray));
You can loop over the array and check for each value if it has a new month and year, or it's already included in the sorted array. I think like this untested code:
new_arr = new Array();
for(var i=0; i < v.length; i++){
var this_date = new Date(v[i]);
var month_and_year = this_date.getMonth() + this_date.getFullYear();
if(typeof(new_arr[month_and_year]) == 'undefined'){
new_arr[month_and_year] = new Array();
}
new_arr[month_and_year].push(v[i])
}
I have a myDate variable with the value 18-Nov-2013.Each day its value is being changed.Tommorow this myDate variable will have the value 19-Nov-2013.I have a list of values that i have mapped into a single array named exclude which contains some dates that are to be excluded ,now it has values ["20-Nov-2013",21-Nov-2013", "23-Nov-2010"] .How could i filter my value from the list of values from the exclude array.I need the next highest value from the array.So here i need the value 22-Nov-2013 after tommorrows date.Could someone help me with this.
var excluded = ["30-Nov-2013","01-Dec-2013","02-Dec-2013"];
var myDate = "29-Nov-2013";
var month = ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec'];
var current = new Date(myDate);
while(true){
current = new Date((current.getDate()+1<10? "0"+(current.getDate()+1):(current.getDate()+1))+ "-" + month[current.getMonth()] + "-" + current.getFullYear());
var checkDate = (current.getDate()<10? "0"+(current.getDate()):(current.getDate()))+ "-" + month[current.getMonth()] + "-" + current.getFullYear();//this is necessary for when the +1 on day of month passes the month barrier
if(-1 == excluded.indexOf(checkDate))
break;
}
alert(checkDate);
I don't know if this is the best approach, or if is the best algorithm, but you may try this:
var myDate = ["17-Nov-2013", "18-Nov-2013"];
var excluded = ["20-Nov-2013", "21-Nov-2013", "23-Nov-2013"];
var months = {"Nov": 10}; // Add others months "Jan": 1, "Fev": 2 etc...
function findExcluded(date)
{
for (var i = 0; i < excluded.length; i++)
{
if (excluded[i] === date)
{
return true;
}
}
return false;
}
function nextDate()
{
var last = myDate[(myDate.length - 1)];
var s = last.split("-");
var d = new Date(s[2], months[s[1]], s[0]);
var next = new Date(d);
var chkDate = "";
do
{
next.setDate(next.getDate() + 1);
chkDate = next.getDate() + "-" + findMonth(next.getMonth()) + "-" + next.getFullYear();
} while(findExcluded(chkDate));
return chkDate;
}
function findMonth(m)
{
var i = 10; // When you fill all months on 'months' array, this variable should start at '0' in order to loop to works.
for (var month in months)
{
if (i == m)
{
return month;
}
i++;
}
}
var nd = nextDate();
alert(nd);
See it woring here.
No code ? Well here will be my method:
1.Get next date for mydate. Say that is var nextDate.
2.Check whether that date exist in the array.
3.If exists add one more day to nextDate. Again check in the array.
4.Do it until you get a date which is not present in your exclude array
For checking whether it exists in the array you can use arrValues.indexOf(nextDateInProperFormat) > -1
