How to output url time string as text instead of video?

I have some code that outputs a time string into a video. I know how to make it output as video or image but I want it to just show up as plain text so I can make a list of live-updating URLs based on the current time.
Currently it is set to "video.r" which adds the time to a "
So that instead of doing:
<video class="r" src="https://mywebsite.com/2019102618URLDATE?=201910261841?New.mp4" type="video/x-flv" width="350"></video>
It would just output as:
https://mywebsite.com/2019102618URLDATE?=201910261841?New.mp4
Here's the code for it.
HTML
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script type="text/javascript" src="screen.js"></script>
<center><h1> URL List </h1></center>
<video class="r" src="https://mywebsite.com/" type="video/x-flv" type="video/mp4" width="350"></video>
JS
$(function() {
var today = new Date();
var ss = today.getSeconds();
var nn = today.getMinutes() * 60 - 90; //60 second delay
var nm = today.getMinutes();
var hh = today.getUTCHours();
var dd = today.getUTCDate();
var mm = today.getUTCMonth() + 1; //January is 0!
var yyyy = today.getUTCFullYear();
if (dd < 10) {
dd = '0' + dd
}
if (mm < 10) {
mm = '0' + mm
}
if (hh < 10) {
hh = '0' + hh
}
if (nm < 10) {
nm = '0' + nm
}
var minsec = nn + ss + 30
var today = yyyy + '' + mm + '' + dd + '' + hh + 'URLDATE?=' + yyyy + '' + mm + '' + dd + '' + hh + nm + '?New.mp4' ;
$('video.r').each(function() {
var url = $(this).attr('src');
if (url.indexOf("?") >= 0) {
$(this).attr("src", url + today);
} else {
$(this).attr("src", url + today);
}
});
});

So, I understand what you want is having a link, which points to an URL like the one you posted.
If so, then it is pretty simple. You already a function that builds the URL, now instead of using this URL as a video's src attribute, you can use it as a link's href attribute:
Edit: Or, if you just want to list URLs as plain text, simply use the link's innerHTML attribute instead of href in the below solution.
$(function() {
var today = new Date();
var ss = today.getSeconds();
var nn = today.getMinutes() * 60 - 90; //60 second delay
var nm = today.getMinutes();
var hh = today.getUTCHours();
var dd = today.getUTCDate();
var mm = today.getUTCMonth() + 1; //January is 0!
var yyyy = today.getUTCFullYear();
if (dd < 10) {
dd = '0' + dd
}
if (mm < 10) {
mm = '0' + mm
}
if (hh < 10) {
hh = '0' + hh
}
if (nm < 10) {
nm = '0' + nm
}
var minsec = nn + ss + 30
var today = yyyy + '' + mm + '' + dd + '' + hh + 'URLDATE?=' + yyyy + '' + mm + '' + dd + '' + hh + nm + '?New.mp4' ;
$('a.r').each(function() { //here change "video.r" to "a.r"
var url = $(this).attr('href'); //and here "src" becomes "href"
if (url.indexOf("?") >= 0) {
$(this).attr("href", url + today);
} else {
$(this).attr("href", url + today);
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script type="text/javascript" src="screen.js"></script>
<center><h1> URL List </h1></center>
<a class="r" href="https://mywebsite.com/">Link</a>

How is this variable still NULL

I'm in the process of writing a CasperJS script to automate a search form and capture the subsequent page. However, the search form goes to a loading splash page first until data arrives. So i added the waitForSelector function which seems to be working for some of my pages, but others return the variable name as NULL. How can that be if it is truly "waiting" for that element to be on the DOM?
casper.each(searchPages,function(casper,index){
var currentTime = new Date();
var month = currentTime.getMonth() + 2;
var day = currentTime.getDate();
var year = currentTime.getFullYear();
var dateStart = month + "/" + day + "/" + year;
month = currentTime.getMonth() + 3;
var dateEnd = month + "/" + day + "/" + year;
casper.thenOpen(url,function(){
var myfile = "data-"+year + "-" + month + "-" + day+".html";
this.evaluate(function(j) {
document.querySelector('select[name="searchParameters.localeId"]').selectedIndex = j;
},index);
this.evaluate(function(start) {
$("#leaveDate").val(start);
},dateStart);
this.evaluate(function(end) {
$("#returnDate").val(end);
},dateEnd);
this.evaluate(function() {
$("#OSB_btn").click();
});
this.waitForSelector('#destinationForPackage', function() {
var name = casper.evaluate(function() {
return $("#destinationForPackage option[value='" + $("#destinationForPackage").val() + "']").text()
});
if (name != "Going To"){
if (name == null){
console.log("it's null");
}else{
name = name.replace("/","_");
casper.capture('Captures/Searches/search_' + name + '.jpg');
console.log("Capturing search_" + name);
}
}
},function(){
console.log("Search page timed-out.");
},20000);
});
});

I was able to solve this by creating a recursive function if the element is still not available. Now i'm having a memory issue though, new question here => CasperJS running out of memory
casper.each(searchPages,function(casper,index){
loadSearch(casper,index);
});
function loadSearch(casper,index){
var currentTime = new Date();
var month = currentTime.getMonth() + 2;
var day = currentTime.getDate();
var year = currentTime.getFullYear();
var dateStart = month + "/" + day + "/" + year;
month = currentTime.getMonth() + 3;
var dateEnd = month + "/" + day + "/" + year;
casper.thenOpen(url,function(){
var myfile = "data-"+year + "-" + month + "-" + day+".html";
this.evaluate(function(j) {
document.querySelector('select[name="searchParameters.localeId"]').selectedIndex = j;
},index);
this.evaluate(function(start) {
$("#leaveDate").val(start);
},dateStart);
this.evaluate(function(end) {
$("#returnDate").val(end);
},dateEnd);
this.evaluate(function() {
$("#OSB_btn").click();
});
this.waitForSelector('#destinationForPackage', function() {
if (this.exists('#destinationForPackage')){
var name = casper.evaluate(function() {
return $("#destinationForPackage option[value='" + $("#destinationForPackage").val() + "']").text()
});
if (name != "Going To"){
if (name == null){
console.log("it's null");
}else{
name = name.replace("/","_");
casper.capture('Captures/Searches/search_' + name + '.jpg');
console.log("Capturing search_" + name);
}
}
}else{
console.log("Still doesn't exist...retry");
loadSearch(casper,index);
}
},function(){
console.log("Search page timed-out.");
},20000);
});

javascript - how to create countdown to date and time from sql server database?

It's my first time using a countdown in javascript so I have researched a little about this topic and I found some interesting links: "how to countdown to a date" and "https://www.sitepoint.com/build-javascript-countdown-timer-no-dependencies/", but my question is if I want to get data and time from the database, how can I do that? E.g.: I have a table Event with ID,Event,StartDate,StartTime and EndTime. How can I change from this: "var end = new Date('02/19/2012 10:1 AM');" from the first link or this: "Schedule the Clock Automatically" from the second to countdown time until event with the most recent time and date, and so on. Please keep in mind that I'm a total nooby so please bear with me. Sorry for any misspelling. Thank you!
Update:
This is the controller part: [HttpGet]
public JsonResult GetEvent(int Id)
{
BOL1.IMS2Entities db = new BOL1.IMS2Entities();
var ev = from e in db.tbl_Event
where e.ID == Id
select e;
//return Json(ev.FirstOrDefault(), JsonRequestBehavior.AllowGet);
return Json(Id, JsonRequestBehavior.AllowGet);
}
and this is the scripting part:
<script>
function GetEvent() {
debugger;
$.ajax({
type: "GET",
url: "Home/GetEvent",
data: { Id: ID },
contentType: "application/json;charset=utf-8",
dataType: "json",
success: function (result) {
debugger;
alert(result)
},
error: function (response) {
debugger;
alert('error');
}
});
}
var tbl_Event.StartDate = 'yyyy-MM-dd hh:hh:hh';
//var ServerDate_Time = '2017-02-17 10:45:00';
//console.log(CompareDateTime(ServerDate_Time));
console.log(CompareDateTime(tbl_Event.StartDate + tbl_Event.StartTime))
//function CompareDateTime (ServerDateTime){
function CompareDateTime (tbl_Event.StartDate + tbl_Event.StartTime){
var dateString = new Date();
var currentTime = new Date(parseInt(dateString));
var month = ('0' + (currentTime.getMonth() + 1)).slice(-2)
var day = ('0' + (currentTime.getDate())).slice(-2)
var year = currentTime.getFullYear();
var hours = ('0' + (currentTime.getHours())).slice(-2)
var min = ('0' + (currentTime.getMinutes())).slice(-2)
var sec = ('0' + (currentTime.getSeconds())).slice(-2)
var date = year + "-" + month + "-" + day + " " + hours + ":" + min + ":" + sec;
if(ServerDateTime == date){
return true;
}else {
return false;
}
}
}
</script>

assuming your datetime you are getting int tbl_Event.StartDate + tbl_Event.StartTime = 2017-02-17 10:45:00
this will go for your..
var ServerDate_Time = '2017-02-17 10:45:00';
console.log(CompareDateTime(ServerDate_Time));
function CompareDateTime (ServerDateTime){
var dateString = new Date();
var currentTime = new Date(parseInt(dateString));
var month = ('0' + (currentTime.getMonth() + 1)).slice(-2)
var day = ('0' + (currentTime.getDate())).slice(-2)
var year = currentTime.getFullYear();
var hours = ('0' + (currentTime.getHours())).slice(-2)
var min = ('0' + (currentTime.getMinutes())).slice(-2)
var sec = ('0' + (currentTime.getSeconds())).slice(-2)
var date = year + "-" + month + "-" + day + " " + hours + ":" + min + ":" + sec;
if(ServerDateTime == date){
return true;
}else {
return false;
}
}
Hope this helps....
Edit after your Edit ....
Updated code...
For Controller --
[HttpGet]
public JsonResult GetEvent(int id)
{
using (IMS2Entities ObjEntities = new IMS2Entities())
{
var ev = from e in ObjEntities.tblEvents
where e.id == id
select e;
return Json(ev.ToList(), JsonRequestBehavior.AllowGet);
}
}
JavaScript code for this
<script>
$(function () {
GetEvent(); // this will call GetEvent function once your DOM is ready, you can call this function on button click or anywhere as per your need.
function GetEvent() {
$.ajax({
type: "GET",
url: "/Home/GetEvent",
data: { Id: '1' }, // '1' is id for my sql database record which is passing to controller to bring back record from server.
success: function (result) {
// result will be collection of list return form server, since you are using id criteria it will always have only 1 record unless you have id as foreign key or something not primary/unique.
// I'm using only first instance of result for demo purpose, you can modify this as per your need.
alert(CompareDateTime(result[0].StartDateTime.substr(6))); // this will alert your true or false, as per I guess this will always return false, as your current date time will never match sql datetime. Still for your requirement.
},
error: function (response) {
alert(response);
}
});
}
function CompareDateTime (ServerDateTimeFormat){
// Convert ServerDateTimeFormat for Comparision
var ServerdateString = ServerDateTimeFormat;
var ServerCurrentTime = new Date(parseInt(ServerdateString));
var Servermonth = ('0' + (ServerCurrentTime.getMonth() + 1)).slice(-2)
var Serverday = ('0' + (ServerCurrentTime.getDate())).slice(-2)
var Serveryear = ServerCurrentTime.getFullYear();
var Serverhours = ('0' + (ServerCurrentTime.getHours())).slice(-2)
var Servermin = ('0' + (ServerCurrentTime.getMinutes())).slice(-2)
var Serversec = ('0' + (ServerCurrentTime.getSeconds())).slice(-2)
var Serverdate = Serveryear + "-" + Servermonth + "-" + Serverday + " " + Serverhours + ":" + Servermin + ":" + Serversec;
// Current Date Time for Comparision
var currentTime = new Date();
var month = ('0' + (currentTime.getMonth() + 1)).slice(-2)
var day = ('0' + (currentTime.getDate())).slice(-2)
var year = currentTime.getFullYear();

This is fully working example.. :)

Daily countdown timer - Display Message at 21:57

I'm struggling to figure out how Date() works, I found this on the web and wanted to make a countdown that stops at 21:57 UTC Time. It currently displays the message at 21:00 and apears until 22:00.
I tried to add if(currenthours != 21 && currentminutes >= 57){ and always broke it and got the message. I want it to stop 3 minutes before 22:00 and display the message. After it gets to 22:00 restart the countdown for the next day at 21:57.
Any help will be greatly appreciated !
var date;
var display = document.getElementById('time');
setInterval(function(){
date = new Date( );
var currenthours = date.getUTCHours();
// alert(currenthours);
var currentminutes = date.getUTCMinutes();
// alert(currentminutes);
var hours;
var minutes;
var secondes;
if (currenthours != 21) {
if (currenthours < 21) {
hours = 20 - currenthours;
} else {
hours = 21 + (24 - currenthours);
}
minutes = 60 - date.getUTCMinutes();
secondes = 60 - date.getUTCSeconds();
display.innerHTML = ('00' + hours).slice(-2) + ' HOURS ' + '<p>' +
('00' + minutes).slice(-2) + ' MINUTES ' + '</p>' +
('00' + secondes).slice(-2) + ' SECONDS';
} else {
display.innerHTML = "IT'S 21:57";
}
},1000);

Date objects are very simple, they're just a time value and some handy methods.
I think your logic just needs to be:
if (currenthours != 21 && currentminutes < 57) {
// set the out of hours message
} else {
// time is from 21:57 to 21:59 inclusive
}
The countdown doesn't quite work because you're counting to 00 not to 57, but otherwise there doesn't seem to be an issue.
var date;
var display = document.getElementById('time');
setInterval(function(){
date = new Date( );
var currenthours = date.getUTCHours();
var currentminutes = date.getUTCMinutes();
var hours;
var minutes;
var secondes;
var limitHr = 5; // Change these to required values
var limitMin = 02; // Using 5:12 for convenience
var message = 'Currently: ' + date.toISOString() + '<p>';
// Create new message if outside limitHr:limitMin to limitHr:59 inclusive
if (currenthours != limitHr || currentminutes < limitMin) {
if (currenthours <= limitHr) {
hours = limitHr - currenthours;
} else {
hours = limitHr + (24 - currenthours);
}
minutes = limitMin - date.getUTCMinutes();
minutes += minutes < 0? 60 : 0;
secondes = 60 - date.getUTCSeconds();
message += ('00' + hours).slice(-2) + ' HOURS ' + '<p>' +
('00' + minutes).slice(-2) + ' MINUTES ' + '</p>' +
('00' + secondes).slice(-2) + ' SECONDS';
} else {
message += 'It\'s on or after ' + limitHr + ':' +
('0'+limitMin).slice(-2) + ' GMT';
}
// Display the message
display.innerHTML = message;
},1000);
<div id="time"></div>
Yes, the timer has issues but that wasn't part of the question. For a counter, it's simpler to just work in time differences, so I've added some methods to Date.prototype for ISO time (to be consistent with ISO Date) and time difference, then use those functions.
The function builds a Date for the end time so that calculations can use Date methods.
// Return the UTC time component of a date in h:mm:ss.sss format
if (!Date.prototype.toISOTime) {
Date.prototype.toISOTime = function() {
return this.getUTCHours() + ':' +
('0' + this.getUTCMinutes()).slice(-2) + ':' +
('0' + this.getUTCSeconds()).slice(-2) + '.' +
('00' + this.getUTCMilliseconds()).slice(-3) + 'Z';
}
}
// Return the difference in time between two dates
// in h:mm:ss.sss format
if (!Date.prototype.timeDiff) {
Date.prototype.timeDiff = function(date2) {
var diff = Math.abs(this - date2);
var sign = this > date2? '+' : '-';
return sign + (diff/3.6e6|0) + ':' + // hours
('0' + ((diff%3.6e6)/6e4|0)).slice(-2) + ':' + // minutes
('0' + ((diff%6e4)/1e3|0)).slice(-2) + '.' + // seconds
('00' + (diff%1e3)).slice(-3); // milliseconds
}
}
function countDown() {
var now = new Date();
var limitHr = 1;
var limitMin = 10;
var limitDate = new Date(+now);
// Set limitDate to next limit time
limitDate.setUTCHours(limitHr, limitMin, 0, 0);
var msg = ['Currently: ' + now.toISOTime() + '<br>' + 'Limit: ' + limitDate.toISOTime()];
var diff;
// If outside limitHr:limitMin to (limitHr + 1):00
if (now.getUTCHours() != limitHr || now.getUTCMinutes() != limitMin) {
if (now > limitDate) limitDate.setDate(limitDate.getDate() + 1);
msg.push(now.timeDiff(limitDate));
} else {
msg.push('It\'s after ' + limitHr + ':' + ('0'+limitMin).slice(-2));
}
document.getElementById('msgDiv2').innerHTML = msg.join('<br>');
}
window.onload = function() {
setInterval(countDown, 1000);
}
<div id="msgDiv2"></div>>
I've left the milliseconds in, round to seconds if you wish.
I've left the timer using setInterval, though I'd prefer to use setTimeout and manually calculate the time to just after the next full second so that it never skips. Most browsers using setTimeout will slowly drift so that they skip a second every now and then. Not really an issue unless you happen to see it, or compare it to the tick of the system clock.

jquery get time from timestamp

I am trying to display Time on my view with format 10: 30 PM PST from time stamp with format like '2012-10-10T06:42:47Z'. I tried different ways to do that and failed. Any good option to display time in that format?
