is there possible to loop javascript function id? I have a form and the form is create using for loop; so I using this autosave javascript to save a draft; now the javascript only run the $("#remark1"). So I need to use for loop to loop the $("#remark1").
<script type="text/javascript">
$(function() {
if (localStorage) {
var content = localStorage.getItem("autoSave");
if(content) {
$("#remark1").text(content);
}
}
$("#remark1").autoSave(function() {
var time = showTime();
$("#msg").text("Draft Autosaved " + time).show();
}, 2000);
$("#refresh").click(function() {
location.reload();
});
$("#clear").click(function() {
localStorage.clear();
location.reload();
});
function showTime() {
var timeNow = new Date();
var hours = timeNow.getHours();
var minutes = timeNow.getMinutes();
var seconds = timeNow.getSeconds();
var timeString = "" + ((hours > 12) ? hours - 12 : hours);
timeString += ((minutes < 10) ? ":0" : ":") + minutes;
timeString += ((seconds < 10) ? ":0" : ":") + seconds;
timeString += (hours >= 12) ? " P.M." : " A.M.";
return timeString;
}
});
I want to loop ("remark1"), any kind solution?
Do you mean something like this?
function dynamicSave( id ) {
$("#" + id).autoSave(function() {
var time = showTime();
$("#msg").text("Draft Autosaved " + time).show();
}, 2000);
}
var ids = [ 'remark1', 'remark2' ];
ids.each(function(id) {
dynamicSave( id );
});

I have developed a countdown timer function.
This function works fine. But the problem is it goes through the minus value too. So I want to stop the counting when its come to the 00:00:00.
How can I do this.please help me?
Javascript
function initCountdown() {
if( seconds == 0 && minutes == 0 && hours == 0 ){
clearInterval( interval ); }
if (seconds < 10) {
outputElement.innerHTML = hours + ": " + minutes + ": " + "0" + seconds + " ";
} else {
outputElement.innerHTML = hours + ": " + minutes + ": " + seconds + " "; }}
function count(){
time[2]--;
if (time[2] == -1) {
time[1]--;
time[2] = 59
}
if (time[1] == -1) {
time[0]--;
time[1] = 59
}
print();
}
var outputElement = document.getElementById('demo');
var time = document.getElementById("picker-dates1").value;
time = time.split(':'); }
HTML
<input type = "text" id = "picker-dates1"/>
<P id="demo"></p>
Replace print(); with if (time[0] >= 0) { print(); }
I'm trying to make an updating JavaScript clock on my webpage. The problem I'm having is that, while the value itself updates (I use alert(timeNow) to show the value and make sure it's updating), the clock on the website doesn't. I was just wondering if there was something I was missing, or if I've just happened to come across something that I can't quite do. I'd prefer if there was a way to do it using jQuery, as I understand that a little better than normal JavaScript.
Javascript:
function updateClock() {
var thisDate = new Date();
if (thisDate.getHours() > 11 && thisDate.getHours() != 0) {
var Hours = Math.abs(thisDate.getHours() - 12);
var AmPm = "PM"
} else {
var Hours = thisDate.getHours()
var AmPm = "AM"
}
if (thisDate.getMinutes() < 10) {
var Mins = "0" + thisDate.getMinutes();
} else {
var Mins = thisDate.getMinutes();
};
var timeNow = thisDate.getDate() + "/" + (thisDate.getMonth() + 1) + "/" + thisDate.getFullYear() + " " + Hours + ":" + Mins + " " + AmPm;
return timeNow;
};
setInterval(updateClock, 1000);
$("span#time").append(updateClock());
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<span id="time"></span>
You are not consuming the return value of updateClock function, thus the updated time is not reflecting.
You should update the text of time span
Use
setInterval(function(){
$("span#time").text(updateClock());
}, 1000);
You are returning the time in the function updateClock(). What you actually want to do is to set it into the DOM at the end of updateClock(). Here is an updated example:
function updateClock() {
var thisDate = new Date();
if (thisDate.getHours() > 11 && thisDate.getHours() != 0) {
var Hours = Math.abs(thisDate.getHours() - 12);
var AmPm = "PM"
} else {
var Hours = thisDate.getHours()
var AmPm = "AM"
}
if (thisDate.getMinutes() < 10) {
var Mins = "0" + thisDate.getMinutes();
} else {
var Mins = thisDate.getMinutes();
};
var timeNow = thisDate.getDate() + "/" + (thisDate.getMonth()+1) + "/" + thisDate.getFullYear() + " " + Hours + ":" + Mins + " " + AmPm;
$("span#time").text(timeNow);
}
setInterval(updateClock, 1000);
You could of course also just use the returned value of updateClock() to update the DOM. In this way, you would separate the DOM manipulation and the JavaScript time calculation. #Satpal described this way.
Try This...
$(document).ready(function()
{
goforit();
});

"Thursday","Friday","Saturday")
var montharray=new Array("January","February","March","April","May","June",

I want to be able to toggle setInterval on click.
Here is my code that start the interval:
var clock = document.querySelector('#hexTime');
var hexClock = document.querySelector('#hexClock');
function run() {
var time = new Date();
var hours = (time.getHours() % 12).toString();
var minutes = time.getMinutes().toString();
var seconds = time.getSeconds().toString();
if(hours.length < 2) {
hours = '0' + hours;
}
if(minutes.length < 2) {
minutes = '0' + minutes;
}
if(seconds.length < 2) {
seconds = '0' + seconds;
}
var clockStr = hours + ' : ' + minutes + ' : ' + seconds;
var hexStr = '#' + hours + minutes + seconds;
clock.textContent = clockStr;
hexClock.textContent = hexStr;
document.body.style.backgroundColor = hexStr;
}
run();
setInterval(run, 1000);
How can I acheive that?
First, add an element (preferably a button) that will listen for the click, give it an ID like:
<button id="myToggleButton">CLICK ME</button>
Then add an event listener for that element and set or clear interval when it's clicked like:
var clock = document.querySelector('#hexTime');
var hexClock = document.querySelector('#hexClock');
function run() {
var time = new Date();
var hours = (time.getHours() % 12).toString();
var minutes = time.getMinutes().toString();
var seconds = time.getSeconds().toString();
if(hours.length < 2) {
hours = '0' + hours;
}
if(minutes.length < 2) {
minutes = '0' + minutes;
}
if(seconds.length < 2) {
seconds = '0' + seconds;
}
var clockStr = hours + ' : ' + minutes + ' : ' + seconds;
var hexStr = '#' + hours + minutes + seconds;
clock.textContent = clockStr;
hexClock.textContent = hexStr;
document.body.style.backgroundColor = hexStr;
}
var myButton = document.querySelector('#myToggleButton');
// this will hold the information about the interval
var myInterval = null;
// the event listener for the click event
myButton.addEventListener("click", function(){
if(myInterval){ // if we have an interval (myInterval != null)
clearInterval(myInterval); // clear it
myInterval = null; // make it null again
}
else{ // if we don't have an interval (myIntervall == null)
myInterval = setInterval(run, 1000); // start one
}
});
// if you don't want the interval to start by default then remove the next line
myInterval = setInterval(run, 1000);
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.
I have one timer and i want it in two different places in my website. But only one is working at the time.
Here is Script + first timer below it.
<script>
var interval;
var minutes = 8;
var seconds = 41;
window.onload = function() {
countdown('countdown');
myFunction();
myFunctiontoo();
}
function countdown(element) {
interval = setInterval(function() {
var el = document.getElementById("timerx");
if(seconds == 0) {
if(minutes == 0) {
el.innerHTML = "Free trial bonus has expired!";
clearInterval(interval);
return;
} else {
minutes--;
seconds = 60;
}
}
if(minutes > 0) {
var minute_text = minutes + (minutes > 1 ? ' minutes' : ' minute');
} else {
var minute_text = '';
}
var second_text = seconds > 1 ? 'seconds' : 'second';
el.innerHTML = minute_text + ' ' + seconds + ' ' + second_text + '';
seconds--;
}, 1000);
}
</script>
<div class="countdown"><span style="color:#EA0423;">Free Trial bonus ends in </span><span id="timerx" style="font-weight:bold;">8 minutes and 42 seconds</span>.
</div>
A bit lower in my HTML code i have another timer.
<span style="color:#FFF1D6;">Free Trial bonus ends in </span><span id="timerx" style="font-weight:bold;">8 minutes and 42 seconds</span>.
The second timer unfortunately is not working.
Method getElementById other than getElementsByClassName return only one DOM element.
Method getElementsByClassName returns an array of elements so you can get them using an index
Here is working example: PLUNKER
You can us getElementsByClassName and your code would look like this:
function countdown(element) {
var start_value = "Free trial bonus has expired!"
interval = setInterval(function() {
var el1 = document.getElementsByClassName("timerx")[0];
var el2 = document.getElementsByClassName("timerx")[1];
if(seconds == 0) {
if(minutes == 0) {
el1.innerHTML = start_value;
el2.innerHTML = start_value;
clearInterval(interval);
return;
} else {
minutes--;
seconds = 60;
}
}
if(minutes > 0) {
var minute_text = minutes + (minutes > 1 ? ' minutes' : ' minute');
} else {
var minute_text = '';
}
var second_text = seconds > 1 ? 'seconds' : 'second';
el1.innerHTML = minute_text + ' ' + seconds + ' ' + second_text + '';
el2.innerHTML = minute_text + ' ' + seconds + ' ' + second_text + '';
seconds--;
}, 1000);
}
If you are calling the timer twice in the same page you need to have two IDs. The id="timerx"
<span id="timerx_"<?php echo 'DYNAMIC VARIBALE'; ?>>timer</span>
And use this new ID
