I need that only the content of the div "chat_scroll" are automatically reloaded. I've tried a lot of codes, but the div remains stationary.
At last, I've tried with this:
JS before
<script>
function updateDiv()
{
$( "#chat_scroll" ).load(window.location.href + " #chat_scroll" );
}
</script>
JQUERY at the bottom of the file:
<script>
function myFunction() {
myVar = setInterval(updateDiv(), 3000);
}
</script>
setInterval accepts a function as an argument:
setInterval(updateDiv, 3000);
Note that there's no () after updateDiv. That would be calling the function, and passing its return value to setInterval, which is not what you're trying to do.
When do you call myFunction()? Try this instead of using myFunction:
$(document).ready(function(){
setInterval(function(){
updateDiv();
}, 3000);
});

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();
});
I have tried the following:
<body id="myBody" onload = "setTimeout('a()', 5000)" / >
Is this the correct method? The reason why I want to do this is because I have my entire website animating in (such as fade ins) on page load. Having my javascript only makes the animation unsmooth.
Any feedback appreciated.
This code will work. Just set your time in milliseconds and write your JS code on loadAfterTime function:
<script>
window.onload = function(){
setTimeout(loadAfterTime, 5000)
};
function loadAfterTime() {
// code you need to execute goes here.
}
</script>
window.addEventListener("load", function () {
animation();
setTimeout(otherOperation, 5000);
}, false);
function animation() {}
function otherOperation() {}
maybe you can use code like this
<body id="myBody" onload = "setTimeout(a, 5000)">
Try this
if you are using jQuery your animation has a callback that you can use to delay the firing of all other javascript events like so:
$( window ).on( 'load', function () {
$( '.someElements' ).animate({
// properties to animate
}, 300, function () {
initScripts();
});
});
function initScripts () {
// call all other functions here
}
The Browser is always load all of your script if any when you open the web page. So It depend on when you call your javascript functions.
Try this:
document.ready(function(){
// your code
});
or
$(function(){
// your code
});
both of them make sure that all of element on your page have been loaded.
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.
Hello how can I edit my following code to reload automatically the content of a specified div?
My code below reloads a file called form.php and I would like to be replaced with a div.
<style>
.loading {
height:24px;
background: url('http://b.static.ak.fbcdn.net/rsrc.php/v1/yb/r/GsNJNwuI-UM.gif') 50% 50% no-repeat;
}
</style>
<script type='text/javascript' src='http://ajax.googleapis.com/ajax/libs/jquery/1.3.0/jquery.min.js'></script>
<script language='JavaScript'>
setInterval( 'SANAjax();', 10000 ); ///////// 10 seconds
$(function()
{
SANAjax = function()
{
$('#reservationdetails')
.empty()
.addClass('loading')
.load('form.php', function()
{
$('#reservationdetails').removeClass('loading')
});
}
});
</script>
Thank you!
Reorder your code:
$(function() {
var SANAjax = function(){
$('#reservationdetails').empty().addClass('loading')
.load('form.php', function() {
$(this).removeClass('loading')
});
}
setInterval(SANAjax, 10000 );
});
I assumed that #reservationdetails is the div you want to load the responce in.
There is no need to pass a string to setInterval. Always pass function reference to it (same for setTimeout).
Felix Kling's answer is correct.
Also worth noting: it is very bad practice to use setInterval in this manner, as you are unsure if .load will return within the 10 seconds you specified. (Think, for example, of mobile devices.) Even if it did return in 9 seconds, it would then be only one second before you fired off the next request. Better to do a setTimeout in the callback, like so:
$(function () {
function loadReservationDetails() {
$('#reservationdetails')
.empty()
.addClass('loading')
.load('form.php', function () {
$(this).removeClass('loading');
setTimeout(loadReservationDetails, 10000);
});
}
loadReservationDetails();
});
Basically I have like 2 images, and I want to show one for 3 seconds, then replace it with another, in the same img tag.
This is what I have so far:
$(function(){
$("#image_area").hide();
$('#W40').click(function(){
$("#image_area img").remove();
show_image_area('40');
});
});
So the flow is first hide the #image_area, then when #W40 button is clicked, remove any current image in the area and run the show_image_area function, the function is as follows:
function show_image_area(world){
if (!$("#image_area img").length) { //only run if no current image exists
$('#image_area').show();
$('#image_area').prepend("<img id='tw_image' src='world+"/7.png' width=\"1000\" height=\"1030\" />");
setTimeout($("#tw_image").attr("src", "world+"/8.png"), 3000);
}
}
Right now, if I run these code, the 8.png shows almost immediately, and there are no 3 second delay that I wanted.
You have an extra " in the code: should be $("#tw_image").attr("src", world+"/8.png").
Also, I would put $("#tw_image").attr("src", world+"/8.png") in a function of it's own.
function SwapImage(world)
{
$("#tw_image").attr("src", world+"/8.png");
}
Then change your last line to setTimeout(SwapImage(world), 3000);
This isnt fully tested but gives you an idea:
$(function(){
$("#image_area").hide();
$('#W40').click(function(){
$("#image_area img").remove()
show_image_area('40');
});
});
function show_image_area(world){
var newImg = $('<img />').css({width: 1000, height: 1030}).attr({id: 'tw_image', src: world+'/7.png');
if ( !$("#image_area img").length ) { //only run if no current image exists
$('#image_area').prepend(newImg).show('fast');
setTimeout( function() {
$("#tw_image").attr("src", world+"/8.png");
}, 3000);
}
}
Basically yours was immediately firing the setTimeout function instead of passing in a function to be fired later
That's because the first parameter of setTimeout is not a function.
Also there is an extra quote on that line.
Also, the "world" variable might need closure (can't remember).
Try
function show_image_area(world){
if (!$("#image_area img").length) { //only run if no current image exists
$('#image_area').show();
$('#image_area').prepend("<img id='tw_image' src='world+"/7.png' width=\"1000\" height=\"1030\" />");
var myWorld = world;
setTimeout(function () {$("#tw_image").attr("src", myWorld+"/8.png");}, 3000);
}
}
Your setTimeout call is a bit off:
setTimeout($("#tw_image").attr("src", "world+"/8.png"), 3000);
The first argument should be the function to execute:
setTimeout(function() { $("#tw_image").attr("src", "world/8.png") }, 3000);
Also, I'm not sure what "world" is so I merged it into the new src path to fix a stray double quote.
