How to refresh a script after some time using Javascript

There is a variable I want to update every minute.
So am curious whether there is a way in Javascript where I can refresh the whole script after some time instead of the variable itself.
<script>
function vName(){
videos = $('#videos').text();
}
vName();

Use setInterval. Here hello will print each and every 3sec
setInterval(function(){ console.log("Hello"); }, 3000);

You could achive this using an event to listen to the element's change:
(function () {
"use strict";
let videos = '';
$("#videos").on("change", evt => {
videos = $(evt.target).val();
console.log(videos);
});
})();
body {
margin: 20px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input id="videos" type="text">

Solution
Set interval is a function which is being used to perform any functionality after a specific desired time span . The function is always called again and again after that time period . The below code is an example for setInterval.
Code:-
setInterval(function(){ alert("Video is here "); }, 9000);
Explanation
you can call any method in place of "alert("Video is here")" and the desired time period is being given in place of "9000" that means the specific function is being called after every 9 seconds

You can put your code in setInterval() function, like this
setInterval(()=>{
//your script here
function vName(){
videos = $('#videos').text();
}
vName();
}, 60000);

<div> value not updating in html page

I am using jquery to auto update a part of the HTML page. Following is the code
$(document).ready( function() {
$('#auto').load("static/l.txt");
refresh();
});
function refresh() {
setTimeout(function() {
$('#auto').load("static/l.txt");
refresh();
}, 1000);
}
The id of the HTML div tag to be updated is auto
The file static/l.txt is continuously being updated by another python program.
But when I load the html page , the div only gets updated once and does not update the value until and unless I open the developers console on the browser.
I am hosting the web page using Flask in python

How about trying this?
var counter =0 ;
$(document).ready( function() {
$('#auto').val("starting");
refresh();
});
function refresh() {
setInterval( function() {
counter ++;
$('#auto').val(counter);
}, 1000);
}

Use a callback to know, when the content is actually loaded and move the function definition in the ready block, also.
$(document).ready(function() {
function loadData() {
$('#auto').load('static/l.txt', function(completed) {
setTimeout(loadData, 1000);
});
}
loadData();
});

clearInterval doesn't work if is in click jquery event?

I want to use clearInterval but I don't know why doesn't work.
var orologio_real; //global variable
$(document).ready(function(){
orologio(1);
$('#change-time').on('click', function(){
clearInterval(orologio_real);
orologio(0);
});
});
function orologio (arg){
orologio_real= setInterval(function(){
alert(arg)
}, 1000);
}
What I don't understand is why if I click on div, clearInterval doesn't work

I think it is a silly mistake. You are setting the time interval all over again inside the click handler. I commented it out, and increased the interval a little so that you get time to click the button
var orologio_real; //global variable
$(document).ready(function(){
orologio(1);
$('#change-time').on('click', function(){
clearInterval(orologio_real);
//orologio(0); //this was the issue
});
});
function orologio (arg){
orologio_real= setInterval(function(){
console.log(arg);
alert(arg);
}, 3000);
}

Change interval in Setinterval

I'm new to jQuery, I wanted to change the interval in Setinterval every time it gets executed. But in my code it's executed every 1 sec and not incrementing at all
Here's my code,
<script>
var time=1000;
function myFunction() {
setInterval(function(){ alert("Hello"); }, time);
time=time+4000;
}
</script>
I think I'm getting this concept wrong, any help with brief explanation where I'm doing wrong will be helpful

setInterval is called till its stopped.
What you should use if you want variable timer is setTimeout.
<script>
var time=1000;
function myFunction() {
setTimeout(function(){ alert("Hello"); myFunction() }, time);
time=time+4000; // seconds
}
</script>

problems with jquery load()

I need a certain div refreshed on the page every 3 seconds. This div contains other divs inside it.
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script>
setInterval(function()
{
$('#gamewrapper2').load('find.php #gamewrapper2');
}, 3000);
;
This code works but only if the page visited is domain/find.php and it doesn't work for domain/find.php?id=1000001
Maybe i don't understand something but shouldn't this function load take the block #gamewrapper2 from find.php and paste it into the block #gamewrapper2 of the current page?

Do you just need to keep the query string on find.php? Something like:
setInterval(function(){
$('#gamewrapper2').load(window.location.pathname + window.location.search + ' #gamewrapper2');
}, 3000);

You can try the following to pass variables into the php document:
setInterval(function()
{
$('#gamewrapper2').load('find.php #gamewrapper2', {id: 1000001});
}, 3000);
}
Additionally, you can provide a function callback when it has completed loading to perform some task...
setInterval(function()
{
$('#gamewrapper2').load('find.php #gamewrapper2', {id: 1000001}, function(){
alert("find.php has been loaded.");
});
}, 3000);
}
.load() method
You should probably use $_POST['id'] to get the value from find.php.
