Filtering a column by date range works nice with solution that i've found in SO
How to define a Kendo grid Column filter between two dates? - proposed by MWinstead
But
"The only problem with this solution is that if you only select the End Date and apply the filter, the next time you open the filter menu, the Begin Date will get populated with the End Date you entered and the LTE operator will be selected, which will be changed by the jQuery code, resulting in a wrong filter"
Question asked by ataravati in the same thread
How we can resolve this issue ?
The soltion is to provide the Begin Date with null value, even if the user hasn't selected it.
But, we must take control of submit button...
function grid_filterMenuInit(e) {
var currentFieldName = e.field;
if(currentFieldName === "yourFieldDate") {
console.info("ignoring this field: <" + currentFieldName + ">");
return;
}
console.info("performing this field: <" + currentFieldName + ">");
var filterSubmit = e.container.find("[type=submit]:eq(0)");
$(filterSubmit).click(function() {
var searchDateAfter = e.container.find("input:eq(0)");
var searchDateAfter1 = $(searchDateAfter).val();
var searchDateBefore = e.container.find("input:eq(1)");
var searchDateBefore1 = $(searchDateBefore).val();
var gridDatasource = $("#yourGridId").data("kendoGrid").dataSource;
var jsDateBefore = null;
var jsDateAfter = null;
// we must convert kendoDateTime to JavaScript DateTime object
// in my case the date time format is : yyyy/MM/dd HH:mm:ss
if (typeof searchDateBefore1 !== 'undefined') {
jsDateBefore = newJsDate(searchDateBefore1);
}
if (typeof searchDateAfter1 !== 'undefined') {
jsDateAfter = newJsDate(searchDateAfter1);
}
var previousFilter = gridDatasource.filter();
var previousFilters = new Array();
var newFilters = new Array();
// storing the previous filters ...
if (typeof previousFilter === 'object' && previousFilter.hasOwnProperty("filters")) {
previousFilters = previousFilter.filters;
for (var i=0 ; i<previousFilters.length ; i++) {
if (previousFilters[i].field !== currentFieldName) {
if (newFilters.length == 0) {
newFilters = [previousFilters[i]];
}
else {
newFilters.push(previousFilters[i]);
}
}
}
}
// this is the soltion : we must provide the first filter, even if the user has not provide the begin date
// and the value will be : null
if (newFilters.length == 0) {
newFilters = [{field: currentFieldName, operator: "gte", value: jsDateAfter }];
}
else {
newFilters.push ({field: currentFieldName, operator: "gte", value: jsDateAfter });
}
if (jsDateBefore !== null) {
newFilters.push ({field: currentFieldName, operator: "lte", value: jsDateBefore });
}
gridDatasource.filter (newFilters);
$(".k-animation-container").hide();
// to stop the propagation of filter submit button
return false;
});
}
function newJsDate(dateTime) {
if (dateTime === null ||
typeof dateTime === 'undefined' ||
dateTime === "") {
return null;
}
var dateTime1 = dateTime.split(" ");
var date = dateTime1[0];
var time = dateTime1[1];
var date1 = date.split("/");
var time1 = time.split(":");
var year = parseInt(date1[0], 10);
var month = parseInt(date1[1], 10);
month = month - 1;
var day = parseInt(date1[2], 10);
var hour = parseInt(time1[0], 10);
var minute = parseInt(time1[1], 10);
var second = parseInt(time1[2], 10);
var jsDate = new Date(year, month, day,
hour, minute, second);
return jsDate;

Plugin: eonasdan/Bootstrap 3 Datepicker
Explaination:
I want to write an application that user can select 5 different hours for each day. so i created an array and add each day (without duplicate), for example user select 31/12/2017 and 30/12/2017 , now i want to give they this ability to select only 5 different hour for each day that selected.
Tried Code:
var limit = 5;
var i = 0;
var dateArray = new Object();
$('#ss').click(function() {
if ($('#datetimepicker1 input').val().length > 0) {
var date = $('#datetimepicker1 input').val();
var getDate = date.split(' ');
var unqdate = getDate[0];
var unqtime = getDate[1];
if ($.inArray(unqdate, dateArray) == -1) {
dateArray[unqdate] = unqtime
}
}
console.log(dateArray);
});
JSFiddle
(For testing, select a date, then click on save button, then check console)
Goal:
var dateArray = {
"31-12-2017": [{
"time": "14:00"
}, {
"time": "17:15"
}],
"30-12-2017": [{
"time": "13:00"
}, {
"time": "12:15"
}]
}
Problem:
I couldn't figured out how can i add another time to each day. it's my first time i work with array and object like this.
I want to prevent duplicate entry and only five different hour per day.
Somehow I'm in learning.
There is some problem with your JS Code:
var limit = 5;
var i = 0;
var dateArray = new Object();
$('#ss').click(function() {
if ($('#datetimepicker1 input').val().length > 0) {
var date = $('#datetimepicker1 input').val();
var getDate = date.split(' ');
var unqdate = getDate[0];
var unqtime = getDate[1];
if ($.inArray(unqdate, dateArray) == -1) {
if(dateArray[unqdate] && dateArray[unqdate].length < limit) {
if(!dateArray[unqdate].find((ele) =>ele.time === unqtime)){
dateArray[unqdate].push({"time": unqtime})
}
} else {
dateArray[unqdate] = [{"time": unqtime}]
}
}
}
console.log(dateArray);
});
Note included logic for time split. You can use split by : and take the first 2 element of array.
I have created JSON response for your requirement.
Result :: JSON.stringify(parentObject)
Code is as below.
$(document).ready(function() {
$('#datetimepicker1').datetimepicker({
stepping: 30,
sideBySide: true,
showTodayButton: true,
format: 'DD-MM-YYYY HH:mm:ss',
});
// my code
var limit = 5;
var i = 0;
var parentObject = new Object();
var parentArray = [];
var dateAndTimeObject;
function isDateSelectedExists(date) {
for (var i = 0; i < parentArray.length; i++) {
var obj = parentArray[i];
if (obj["date"] === date) {
return i;
}
}
return -1;
}
$('#ss').click(function() {
if ($('#datetimepicker1 input').val().length > 0) {
var date = $('#datetimepicker1 input').val();
var getDate = date.split(' ');
var unqdate = getDate[0];
var unqtime = getDate[1];
var tempIndex = isDateSelectedExists(unqdate);
console.log("tempIndex :: " + tempIndex);
if (tempIndex == -1) {
console.log("date doesn't exists");
dateAndTimeObject = new Object();
dateAndTimeObject["date"] = unqdate;
var timeArray = [];
timeArray.push(unqtime);
dateAndTimeObject["time"] = timeArray;
parentArray.push(dateAndTimeObject);
parentObject["res"] = parentArray;
} else {
console.log("date exists");
dateAndTimeObject = parentArray[tempIndex];
var timeArray = dateAndTimeObject["time"];
if(timeArray.length<5) timeArray.push(unqtime);
dateAndTimeObject["time"] = timeArray;
}
console.log("final res :: " + JSON.stringify(parentObject));
}
});});
I want to create a array containing objects, and I'm using Parse to query all the data.
However, the for loop which loops over the results doesn't does that in the correct order but randomly loops over the data. If I log i each iteration, the logs show different results every time.
Here is my code:
for (var i = 0; i < results.length; i++)
{
Parse.Cloud.useMasterKey();
// retrieve params
var objectid = results[i];
var self = request.params.userid;
// start query
var Payment = Parse.Object.extend("Payments");
var query = new Parse.Query(Payment);
query.get(objectid, {
success: function (payment) {
// get all the correct variables
var from_user_id = payment.get("from_user_id");
var to_user_id = payment.get("to_user_id");
var amount = payment.get("amount");
var createdAt = payment.updatedAt;
var note = payment.get("note");
var img = payment.get("photo");
var location = payment.get("location");
var status = payment.get("status");
var fromquery = new Parse.Query(Parse.User);
fromquery.get(from_user_id, {
success: function(userObject) {
var fromusername = userObject.get("name");
var currency = userObject.get("currency");
var toquery = new Parse.Query(Parse.User);
toquery.get(to_user_id, {
success: function(touser)
{
var tousername = touser.get("name");
if(tousername !== null || tousername !== "")
{
sendArray(tousername);
}
},
error: function(touser, error)
{
var tousername = to_user_id;
if(tousername !== null || tousername !== "")
{
sendArray(tousername);
}
}
});
function sendArray(tousername) {
var array = new Array();
// create the time and date
var day = createdAt.getDate();
var year = createdAt.getFullYear();
var month = createdAt.getMonth();
var hour = createdAt.getHours();
var minutes = createdAt.getMinutes();
// create the timestamp
var time = "" + hour + ":" + minutes;
var date = "" + day + " " + month + " " + year;
var associativeArray = {};
if(self == from_user_id)
{
fromusername = "self";
}
if(self == to_user_id)
{
tousername = "self";
}
associativeArray["from"] = fromusername;
associativeArray["to"] = tousername;
associativeArray["amount"] = amount;
associativeArray["currency"] = currency;
associativeArray["date"] = date;
associativeArray["time"] = time;
associativeArray["status"] = status;
if(note == "" || note == null)
{
associativeArray["note"] = null;
}
else
{
associativeArray["note"] = note;
}
if(img == "" || img == null)
{
associativeArray["img"] = null;
}
else
{
associativeArray["img"] = img;
}
if(location == "" || location == null)
{
associativeArray["location"] = null;
}
else
{
associativeArray["location"] = location;
}
array[i] = associativeArray;
if((i + 1) == results.length)
{
response.success(array);
}
},
error: function(userObject, error)
{
response.error(106);
}
});
},
error: function(payment, error) {
response.error(125);
}
});
}
But the i var is always set to seven, so the associative arrays are appended at array[7] instead of the correct i (like 1,2,3,4,5)
The reason that this is so important is because I want to order the payment chronologically (which I have done in the query providing the results).
What can I do to solve this issue?
Success is a callback that happens at a later point in time. So what happens is, the for loop runs 7 times and calls parse 7 times. Then after it has run each of parse success calls will be executed, they look at i which is now at 7.
A simple way to fix this is to wrap the whole thing in an immediate function and create a new closure for i. Something like this
for(var i = 0; i < results.length; i++){
function(iClosure) {
//rest of code goes here, replace i's with iClosure
}(i);
}
Now what will happen is that each success function will have access to it's own iClosure variable and they will be set to the value of i at the point they were created in the loop.
i'm trying to do a function in javascript inorder to catch a file that have the last date. My problème is how to compare the date value that is found in an array. I have tried the code below
//indentifiant[0] is an id that i caught in the file name
//all_response is the content of the file
var timeSusDat = stats.mtime + all_response;
if (filesPerUser[identifiant[0]]) {
filesPerUser[identifiant[0]].push(timeSusDat);
} else {
var testtab = [timeSusDat];
filesPerUser[identifiant[0]] = testtab;
};
function onlyLastDate(table) {
for (var d in table) {
id = table[d];
for (var db in table[d]) {
data = table[d][db];
date = data.split('/');
var testDate = new Date(date[0]).getTime();
console.log(testDate);
}
}
}
function rangeDate(testDate){
var dateStart = new Date($('#dateStart').val()).getTime();
var dateEnd = new Date($('#dateEnd').val()).getTime();
if (dateStart <= testDate && testDate <= dateEnd) {
date = true;
return date;
}else{
date = false;
return date;
}
}
I have found similar threads about this but I cant seem to make their solutions work for my specific issue. I currently have a calendar that will highlight the starting date of an Event. I need to change this to highlight the Start Date through the End Date.
Note: I did not write this code. It seems like whoever wrote this left a lot of junk in here. Please don't judge.
attachTocalendar : function(json, m, y) {
var arr = new Array();
if (json == undefined || !json.month || !json.year) {
return;
}
m = json.month;
y = json.year;
if (json.events == null) {
return;
}
if (json.total == 0) {
return;
}
var edvs = {};
var kds = new Array();
var offset = en4.ynevent.getDateOffset(m, y);
var tds = $$('.ynevent-cal-day');
var selected = new Array(), numberOfEvent = new Array();
for (var i = 0; i < json.total; ++i) {
var evt = json.events[i];
var s1 = evt.starttime.toTimestamp();
var s0 = s1;
var s2 = evt.endtime.toTimestamp();
var ds = new Date(s1);
var de = new Date(s2);
var id = ds.getDateCellId();
index = selected.indexOf(id);
if (index < 0)
{
numberOfEvent[selected.length] = 1;
selected.push(id);
}
else
{
numberOfEvent[index] = numberOfEvent[index] + 1;
}
}
for (var i = 0; i < selected.length; i++) {
var td = $(selected[i]);
if (td != null) {
if (!(td.hasClass("otherMonth"))){
td.set('title', numberOfEvent[i] + ' ' + en4.core.language.translate(numberOfEvent[i] > 1 ? 'events' : 'event'));
td.addClass('selected');
}
}
}
},
Instead of trying to select them all, I recommend you iterate over them instead. So something like this:
function highlightDates(startDate, endDate) {
var curDate = startDate;
var element;
$('.selected').removeClass('selected'); // reset selection
while (curDate <= endDate) {
element = getElementForDate(curDate)
element.addClass('selected');
curDate.setDate(curDate.getDate() + 1); // add one day
}
}
function getElementForDate(someDate) {
return $('#day-' + someDate.getYear() + "-" + someDate.getMonth() + "-" + someDate.getDay());
}
I have this code that updates a calendar widget and input field, while validating the date. We want the user to be able to input any type of m-d-y format (m.d.y, m-d-y, and so on). The problem is the YUI calendar widget only accepts the m/d/y format. All others it returns as NaN. I have tried a couple ways to format the date, but can't get anything that seems to work. I would like to be able to do this with out a lot of overblown code. Does anyone have any suggestions as to the best approach here? Here is my code:
//CALENDAR --------------------------------------------------------------------------------
var initCal = function(calendarContainer){
if(YAHOO.env.getVersion("calendar")){
var txtDate = Dom.get("dateOfLoss");
var myDate = new Date();
var day = myDate.getDate();
var month = myDate.getMonth() +1;
var year = myDate.getFullYear() -1;
var newDate = month + "/" + day + "/" + year;
function handleSelect(type, args, obj){
var dates = args[0];
var date = dates[0];
var year = date[0], month = date[1], day = date[2];
txtDate.value = month + "/" + day + "/" + year;
aCal.hide();
}
function updateCal(){
if (!(txtDate.value.match(/((\d{2})|(\d))\/|\-((\d{2})|(\d))\/|\-((\d{4})|(\d{2}))/))) {
alert("Enter date in mm/dd/yy or mm/dd/yyyy format.");
}
else {
if (txtDate.value != "") {
aCal.select(txtDate.value);
var selectedDates = aCal.getSelectedDates();
if (selectedDates.length > 0) {
var firstDate = selectedDates[0];
aCal.cfg.setProperty("pagedate", (firstDate.getMonth() + 1) + "/" + firstDate.getFullYear());
aCal.render();
}
else {
alert("Date of Loss must be within the past year.");
}
}
}
}
var aCal = new YAHOO.widget.Calendar(null, calendarContainer, {
mindate: newDate,
maxdate: new Date(),
title: "Select Date",
close: true
});
aCal.selectEvent.subscribe(handleSelect, aCal, true);
aCal.render();
Event.addListener("update", "click", updateCal);
Event.addListener(txtDate, "change", function(e){
updateCal();
});
// Listener to show the 1-up Calendar when the button is clicked
// Hide Calendar if we click anywhere in the document other than the calendar
Event.on(document, "click", function(e){
var el = Event.getTarget(e);
if(Dom.hasClass(el, "calendarButton"))
aCal.show();
else if (Dom.hasClass(el, "link-close") || !Dom.isAncestor(calendarContainer, el))
aCal.hide();
});
}
else {
var successHandler = function() {
initCal(calendarContainer);
};
OURPLACE.loadComponent("calendar", successHandler);
}
};
Did you tried http://www.datejs.com/?
Maybe you can define some patterns and test agaist the input.
How can I convert string to datetime with format specification in JavaScript?
var updateCal = function(){
if (!(txtDate.value.match(/^(0?[1-9]|1[012])[- /.](0?[1-9]|[12][0-9]|3[01])[- /.]\d\d+$/))) {
return;
}
//else if ((txtDate.value.match(/^(0?[1-9]|1[012])[- .](0?[1-9]|[12][0-9]|3[01])[- .]\d\d+$/))) {
//}
else {
var changedDate = txtDate.value;
changedDate = changedDate.replace(/[. -]/g, "/");
txtDate.value = changedDate;
badClaimDate = claimDateWithinPastYear();
aCal.select(changedDate);
I used a RegEx to determine which, if any, delimiters needed to be replaced and simply used .replace.
