My script is working well, but the only problem i have.
i want to show the counter in human readable style, becouse now its showing in milliseconds
i want like time left is 1:02 Minutes
so i want to display time left in readable style in browser not milliseconds
<!DOCTYPE html>
<html>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<body>
<p>Time left: <span id="timr"></span></p>
<p id="hpd">Welcome here john</p>
<p id="shp" style="display:none">Your time is up</p>
<input type="button" value="Hi john" id="btn">
<script>
var SessionTime=100000;
var tickDuration=1000;
var myInterval=setInterval(function(){
SessionTime=SessionTime-tickDuration
$("#timr").text(SessionTime);
},1000);
var myTimeOut=setTimeout(SessionExpireEvent,SessionTime);
$("input").click(function(){
clearTimeout(myTimeOut);
SessionTime=100000;
myTimeOut=setTimeout(SessionExpireEvent,SessionTime);
});
function SessionExpireEvent()
{ clearInterval(myInterval);
$("#btn").attr("disabled", true);
$("#hpd").hide();
$("#shp").show();
}
</script>
</body>
</html>
You can simply replace
$("#timr").text(SessionTime);
with
$("#timr").text(`${Math.floor(SessionTime/60000)}:${SessionTime/1000%60}`);
However, your code can be simpler if you don't need to know how much time is left to milliseconds precision.
setInterval and setTimeout are the only functions in your code that need their arguments in milliseconds.
<!DOCTYPE html>
<html>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<body>
<p>Time left: <span id="timr"></span></p>
<p id="hpd">Welcome here john</p>
<p id="shp" style="display:none">Your time is up</p>
<input type="button" value="Hi john" id="btn">
<script>
var SessionTimeInSec = 40;
var myInterval = setInterval(function() {
SessionTimeInSec--;
$("#timr").text(`${Math.floor(SessionTimeInSec/60)}:${SessionTimeInSec%60}`);
}, 1000);
var myTimeOut = setTimeout(SessionExpireEvent, SessionTimeInSec*1000);
$("input").click(function() {
clearTimeout(myTimeOut);
SessionTimeInSec = 40;
myTimeOut = setTimeout(SessionExpireEvent, SessionTimeInSec*1000);
});
function SessionExpireEvent() {
clearInterval(myInterval);
$("#btn").attr("disabled", true);
$("#hpd").hide();
$("#shp").show();
}
</script>
</body>
</html>
I did the following changes:
Change SessionTime to SessionTimeInSec and divide numbers by 1000.
Multiple SessionTimeInSec by 1000 for the arguments passed to both funtions setInterval and setTimeout.
Get rid of tickDuration since it will equal to one. Consonantly, change SessionTime = SessionTime - tickDuration to SessionTimeInSec--.
Change $(#timr) text to 0:0 in SessionExpireEvent()
Seems like you want something like this:
var mins = Math.floor(SessionTime / 1000 / 60);
SessionTime %= 60000;
var secs = SessionTime / 1000;
$("#timr").text(mins + ":" + secs);

I'm looking for some solution to manipulate a part of HTML body scrip function by injecting some code using tampermonkey on every site load. The purpose of this workaround is to manipulate function behavior. Here's a simple example of what it's going to do:
<html>
<body>...</body>
<script type="text/javascript">...</script>
<script type="text/javascript">
function dosome() {
...
};
function startTimer() {
var countDownTime = 1000 * 60;
...
};
</script>
</html>
For instance in code above, line var countDownTime = 1000 * 60; changes to var countDownTime = 1000 * 45;
You could attempt it by having the parameter be inputted through an input field. See code example below:
<html>
<body>
<input type="number" id="testInput" name="testInput" value="0">
<button type="button" onclick="startTimer()">Submit</button>
<p id="output">Output: </p>
</body>
<script type="text/javascript">
function startTimer() {
var countDownTime = 1000 * document.getElementById("testInput").value;
document.getElementById("output").innerHTML = 'Output: ' + countDownTime;
};
</script>
</html>
You could also make the call from within a button by using the OnClick event.
I have a little game, I want to set a timer for it for 1 second, yet I keep failing.
The timer makes the balance randomly jump from 0 to 13000 + some change.
<script>
var satoshi = 0; var hash = 1;
</script>
<center>
<h4>
Hashs Per Second:
<script type="text/javascript">
document.write(hash)
</script>
</h4>
</center>
<center>
<p id="cookiespersecond">Satoshis: 0</p>
</center>
<button onclick="minebtc()"><img src="kop.png" height=28 width=32>Mine BTC</button>
<button onclick="stop()"><img src="kop.png" height=28 width=32>Stop Mining BTC</button>
<script>
function minebtc() {
satoshi = satoshi + hash
update()
}
function update() {
document.getElementById('cookiespersecond').innerHTML = "Satoshis: " + satoshi;
setTimeout(update, 3000)
minebtc()
}
function stop() {
}
</script>
Your RangeError is caused by minebtc calling update and that one calling minebtc over and over again, without letting the code finish running (therefore allowing for other stuff to be inserted in the event loop). To fix this, you can simply call minebtc with a 0ms timer, this basically allows for other events to interleave their code between your mutual recursion.
<script>
var satoshi = 0; var hash = 1;
</script>
<center>
<h4>
Hashs Per Second:
<script type="text/javascript">
document.write(hash)
</script>
</h4>
</center>
<center>
<p id="cookiespersecond">Satoshis: 0</p>
</center>
<button onclick="minebtc()"><img src="kop.png" height=28 width=32>Mine BTC</button>
<button onclick="stop()"><img src="kop.png" height=28 width=32>Stop Mining BTC</button>
<script>
function minebtc() {
satoshi = satoshi + hash;
setTimeout(update, 3000);
}
function update() {
document.getElementById('cookiespersecond').innerHTML = "Satoshis: " + satoshi;
setTimeout(minebtc, 0)
}
function stop() {
}
</script>
Hi I wanted to get my inscription "something" and show it on the screen every 2 seconds.
Something doesn't work. Thanks for all help :)
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<div id = "word">something</div>
<script type="text/javascript">
var myVar = document.getElementById("word");
setInterval(function func1(){
document.write(myVar)
},2000);
func1();
</script>
</body>
</html>
Use this
var myVar = document.getElementById("word").innerHTML;
You don't need to run the function manually, setInterval will execute it every 2 seconds.
setInterval(() => {
const word = document.getElementById('word');
const output = document.getElementById('output');
output.innerHTML = word.innerHTML;
}, 2000);
<div id="word">Something</div>
<div id="output"></div>
add innerHTML to extract data from div.
You don't need to name the recurring function.
var myVar = document.getElementById("word").innerHTML;
setInterval(function(){
document.write(myVar);
// alert(myvar);
},2000);
<div id="word">test</div>
Hi this is my first javascript and it is not working. The script is programmed to display a clock. The code is as follows:
<html>
<head>
<script type="text/javascript" src="clock.js" > </script>
</head>
<body onload=display_ct();>
<span id='ct' ></span>
</body>
</html>
The javascript is :
function display_c(){
var refresh=1000; // Refresh rate in milli seconds
mytime=setTimeout('display_ct()',refresh)
}
function display_ct() {
var strcount
var x = new Date()
document.getElementById('ct').innerHTML = x;
tt=display_c();
}
When execute I get a blank screen. What and where is the mistake ?
TIA :)
You should probably be consistent with ending lines in semi-colon. Also, you should check that clock.js is loading; finally put the onload handler in quotes like
function display_c() {
var refresh = 1000; // Refresh rate in milli seconds
mytime = setTimeout('display_ct()', refresh);
}
function display_ct() {
var x = new Date();
document.getElementById('ct').innerHTML = x;
tt = display_c();
}
<html>
<body onload="display_ct();">
<span id='ct'></span>
</body>
</html>
Please enclose your onload attribute value of body tag inside " " .
It should be
<body onload="display_ct();">
Try using setInterval(), also this line won't work in some browsers:
setTimeout('display_ct()',refresh)
var ct;
function display_c() {
//timer block
setInterval(function() {
ct.innerHTML = new Date().toString();
}, 1000); //execute every 1 second
}
function display_ct() {
ct = document.getElementById('ct'); //initialize once.
display_c();
}
<!-- onload, enclosed in quotes -->
<body onload="display_ct()">
<span id='ct'>Loading ...</span>
</body>
You made two errors when entering the display_ct function. You needed to wrap the <body>'s onload event with quotes, and remove the quotes and the parentheses on the setTimeout. See below.
function display_c() {
var refresh = 1000; // Refresh rate in milli seconds
mytime = setTimeout(display_ct, refresh);
}
function display_ct() {
var x = new Date();
document.getElementById('ct').innerHTML = x;
display_c();
}
<html>
<head>
<script type="text/javascript" src="clock.js">
</script>
</head>
<body onload="display_ct()">
<span id='ct'></span>
</body>
</html>
I am looking for a quick script that will update a number daily. This is for something like the number of days without an accident in the work place.
I want it to to put an link to the HTML page for it in the startup group in XP (yes XP, company is a little behind) and have it run at bootup. I may add more stuff later but this is the main purpose.
So each day it needs to update the number by 1 based on the previous days number, so it is most likely going to have to be read and written to a file. If the browser is closed or the system rebooted it should not update increment the browser unless it is a different day.
Can someone point me to a good way of doing this. I was thinking javascript, but I am open. I have no access to a database.
Thanks
This script should do the trick
HTML
<div id="counter">1</div>
<button id="reset">Reset</button>
JS
setInterval(function(){
var value = parseInt(document.getElementById('counter').innerHTML);
document.getElementById('counter').innerHTML = (value+1).toString();
},86400000); //86400000 = 1 day in milliseconds
var btn = document.getElementById('reset');
btn.onclick=function(){
document.getElementById('counter').innerHTML = "0";
};

Well than you may wanna use HTML5 to save variables within the web browser, so if you happen to reload or reboot the computer you still have your variables saved. Code may look something like this:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Hello HTML5</title>
<script>
window.onload = function (){
if(typeof(Storage)!=="undefined"){
var goodDays;
var oldTime = localStorage.getItem("oldTime");
var timestamp = new Date().getTime();
if(!oldTime || oldTime==""){
goodDays = 1;
localStorage.setItem("oldTime", timestamp);
localStorage.setItem("dayCounter", goodDays);
}else{
var timeCheck = oldTime + (24 * 60 * 60 * 1000);
goodDays = localStorage.getItem("dayCounter");
if(timestamp > timeCheck){
goodDays++;
localStorage.setItem("oldTime", timestamp);
localStorage.setItem("dayCounter", goodDays);
}
}
document.getElementById("dCounter").innerHTML=goodDays;
}else{
alert("geat a real browser");
}
}
function resetDays(){
localStorage.setItem("oldTime", "");
localStorage.setItem("dayCounter", "");
location.reload();
}
</script>
</head>
<body>
<div style="display:inline">DAYS WITH OUT INCENDENTS </div><div style="display:inline" id="dCounter"></div>
<div style="cursor:pointer" onclick="resetDays()">Reset</div>
</body>
</html>
