I want to make a function that will automatically display items as the user scrolls upwards. Think messages, where older ones are up top, but we start at the bottom with the newest ones. I have another function that loads items at the bottom of a container, and as it does so, the current items remain in position, and scrollbar is smaller. We are not scrolled to the bottom. However, with the other direction, when I prepend items to an array, it scrolls all the way to the top, displaying the top of the loaded items, instead of remaining in the same place and letting the user scroll up as needed.
My code for the bottom scroll is this:
attachScrollWatcher: function (element, offset, callback) {
console.log('scrolling');
var contentHeight = element.scrollHeight;
var yOffset = element.scrollTop;
var y = yOffset + element.offsetHeight;
if (y >= ( contentHeight - offset ))
{
callback();
}
}
This function is attached to an object's onscroll event. However, now I need to make a function that does the opposite, going upwards. Any ideas how this can be implemented?
Basically, when scrollTop === 0 then you're at the top and you need to load a new item..
attachScrollWatcher: function (element, offset, callback) {
if(!element.scrollHeight) callback();
}
The problem is, loading a new item will keep the scrollTop at zero, so the user would have to scroll down and then scroll back up in order for the callback to be triggered again. So, what you wanna do is calculate the scrollHeight before the new item is added and then again after the item is added and then manually set the scrollTop to the difference between the original and the new scrollHeight.
Check out my example attachScrollListener method below...
class upScroller{
constructor(ele = document.body){
this.renderedItems = 0;
this.ele = ele; var i=0;
this.initBoxContents();
}
initBoxContents(){
if(this.ele.scrollHeight == this.ele.clientHeight)
this.populateNextItem().then(()=>this.initBoxContents());
else{
this.ele.scrollTop = this.ele.clientHeight;
this.attachScrollListener();
}
}
getNextItem(){
// Do something here to get the next item to render
// preferably using ajax but I'm using setTimeout
// to emulate the ajax call.
return new Promise(done=>setTimeout(()=>{
this.renderedItems++;
done(`<p>This is paragraph #${this.renderedItems}</p>`);
},50));
}
populateNextItem(){
return new Promise(done=>{
this.getNextItem().then(item=>{
this.ele.insertAdjacentHTML('afterbegin', item);
done();
});
});
}
attachScrollListener(){
this.ele.addEventListener('scroll', ()=>{
if(this.ele.scrollTop) return;
var sh = this.ele.scrollHeight;
this.populateNextItem().then(()=>{
this.ele.scrollTop = this.ele.scrollHeight - sh;
});
});
}
}
var poop = document.getElementById('poop');
new upScroller(poop);
#poop{ height: 300px; overflow: auto; border:1px solid black;}
<div id=poop></div>
I've posted this here as well....
Something like this may work.
attachScrollWatcher: function (element, offset, callback) {
console.log('scrolling');
var contentHeight = element.scrollHeight;
var yOffset = element.scrollTop;
var y = yOffset + element.offsetHeight;
if (y >= ( contentHeight - offset ))
{
callback();
} else {
callbackGoingUp();
}
}

I have a situation where, for example, if a user's scroll will result in a 1000 px change in scrollTop I'd like to know ahead of time.
The perfect example is iCalendar's control over a user's scroll. No matter how hard you scroll in the iCalendar application, the farthest you can scroll is to the next or previous month.
I currently have a very hackish solution to limit scroll behavior, which only takes into account where the user's scroll currently is.
MyConstructor.prototype._stopScroll = function(){
//Cache the previous scroll position and set a flag that will control
//whether or not we stop the scroll
var previous = this._container.scrollTop;
var flag = true;
//Add an event listener that stops the scroll if the flag is set to true
this._container.addEventListener('scroll', function stop(){
if(flag) {
this._container.scrollTop = previous;
}
}.bind(this), false);
//Return a function that has access to the stop function and can remove it
//as an event listener
return function(){
setTimeout(function(){
flag = false;
this._container.removeEventListener('scroll', stop, false);
}.bind(this), 0);
}.bind(this);
};
This approach works, and will stop a scroll in progress, but it is not smooth and I'd love to know if there's a better way to accomplish this.
The key to this question is can I know ahead of time where a scroll will end up. Thanks!!!
Edit: Just found the following project on github:
https://github.com/jquery/jquery-mousewheel
I tried the demo and it's able to report my touchpad and mouse scroll speed. Also it able to stop scrolling without any position fixed hacks :D
I'll have a look in the next few days and see if I can write anything that reports scroll speed, direction, velocity, device etc. Hopefully I'm able to make some jquery plugin that can override all scrolling interaction.
I'll update this post when I've got more info on this subject.
It's impossible to predict where a mouse scroll will end up.
A touchscreen/touchpad swipe on the other hand has a certain speed that will slow down after the user stopped swiping, like a car that got a push and starts slowing down afterwards.
Sadly every browser/os/driver/touchscreen/touchpad/etc has it's own implementation for that slowing down part so we can't predict that.
But we can of course write our own implementation.
We got 3 implementations that could be made:
A. Direction
B. Direction and speed
C. Direction, speed and velocity
iCalender probably uses implementation A.
Implementation A:
Outputs scroll direction to console, user is able to scroll +/- 1px
before the direction is detected.
Demo on JSFiddle
Demo with animation on JSFiddle
(function iDirection() {
var preventLoop = true;
var currentScroll = scrollTop();
function scroll() {
if(preventLoop) {
//Get new scroll position
var newScroll = scrollTop();
//Stop scrolling
preventLoop = false;
freeze(newScroll);
//Check direction
if(newScroll > currentScroll) {
console.log("scrolling down");
//scroll down animation here
} else {
console.log("scrolling up");
//scroll up animation here
}
/*
Time in milliseconds the scrolling is disabled,
in most cases this is equal to the time the animation takes
*/
setTimeout(function() {
//Update scroll position
currentScroll = newScroll;
//Enable scrolling
unfreeze();
/*
Wait 100ms before enabling the direction function again
(to prevent a loop from occuring).
*/
setTimeout(function() {
preventLoop = true;
}, 100);
}, 1000);
}
}
$(window).on("scroll", scroll);
})();
Implementation B:
Outputs scroll direction, distance and average speed to console, user is able to scroll the amount of pixels set in the distance variable.
If the user scrolls fast they might scroll a few more pixels though.
Demo on JSFiddle
(function iDirectionSpeed() {
var distance = 50; //pixels to scroll to determine speed
var preventLoop = true;
var currentScroll = scrollTop();
var currentDate = false;
function scroll() {
if(preventLoop) {
//Set date on scroll
if(!currentDate) {
currentDate = new Date();
}
//Get new scroll position
var newScroll = scrollTop();
var scrolledDistance = Math.abs(currentScroll - newScroll);
//User scrolled `distance` px or scrolled to the top/bottom
if(scrolledDistance >= distance || !newScroll || newScroll == scrollHeight()) {
//Stop scrolling
preventLoop = false;
freeze(newScroll);
//Get new date
var newDate = new Date();
//Calculate time
var time = newDate.getTime() - currentDate.getTime();
//Output speed
console.log("average speed: "+scrolledDistance+"px in "+time+"ms");
/*
To calculate the animation duration in ms:
x: time
y: scrolledDistance
z: distance you're going to animate
animation duration = z / y * x
*/
//Check direction
if(newScroll > currentScroll) {
console.log("scrolling down");
//scroll down animation here
} else {
console.log("scrolling up");
//scroll up animation here
}
/*
Time in milliseconds the scrolling is disabled,
in most cases this is equal to the time the animation takes
*/
setTimeout(function() {
//Update scroll position
currentScroll = newScroll;
//Unset date
currentDate = false;
//Enable scrolling
unfreeze();
/*
Wait 100ms before enabling the direction function again
(to prevent a loop from occuring).
*/
setTimeout(function() {
preventLoop = true;
}, 100);
}, 1000);
}
}
}
$(window).on("scroll", scroll);
})();
Implementation C:
Outputs scroll direction, distance and speeds to console, user is able to scroll the amount of pixels set in the distance variable.
If the user scrolls fast they might scroll a few more pixels though.
Demo on JSFiddle
(function iDirectionSpeedVelocity() {
var distance = 100; //pixels to scroll to determine speed
var preventLoop = true;
var currentScroll = [];
var currentDate = [];
function scroll() {
if(preventLoop) {
//Set date on scroll
currentDate.push(new Date());
//Set scrollTop on scroll
currentScroll.push(scrollTop());
var lastDate = currentDate[currentDate.length - 1];
var lastScroll = currentScroll[currentScroll.length - 1];
//User scrolled `distance` px or scrolled to the top/bottom
if(Math.abs(currentScroll[0] - lastScroll) >= distance || !lastScroll || lastScroll == scrollHeight()) {
//Stop scrolling
preventLoop = false;
freeze(currentScroll[currentScroll.length - 1]);
//Total time
console.log("Time: "+(lastDate.getTime() - currentDate[0].getTime())+"ms");
//Total distance
console.log("Distance: "+Math.abs(lastScroll - currentScroll[0])+"px");
/*
Calculate speeds between every registered scroll
(speed is described in milliseconds per pixel)
*/
var speeds = [];
for(var x = 0; x < currentScroll.length - 1; x++) {
var time = currentDate[x + 1].getTime() - currentDate[x].getTime();
var offset = Math.abs(currentScroll[x - 1] - currentScroll[x]);
if(offset) {
var speed = time / offset;
speeds.push(speed);
}
}
//Output array of registered speeds (milliseconds per pixel)
console.log("speeds (milliseconds per pixel):");
console.log(speeds);
/*
We can use the array of speeds to check if the speed is increasing
or decreasing between the first and last half as example
*/
var half = Math.round(speeds.length / 2);
var equal = half == speeds.length ? 0 : 1;
var firstHalfSpeed = 0;
for(var x = 0; x < half; x++ ) {
firstHalfSpeed += speeds[x];
}
firstHalfSpeed /= half;
var secondHalfSpeed = 0;
for(var x = half - equal; x < speeds.length; x++ ) {
secondHalfSpeed += speeds[x];
}
secondHalfSpeed /= half;
console.log("average first half speed: "+firstHalfSpeed+"ms per px");
console.log("average second half speed: "+secondHalfSpeed+"ms per px");
if(firstHalfSpeed < secondHalfSpeed) {
console.log("conclusion: speed is decreasing");
} else {
console.log("conclusion: speed is increasing");
}
//Check direction
if(lastScroll > currentScroll[0]) {
console.log("scrolling down");
//scroll down animation here
} else {
console.log("scrolling up");
//scroll up animation here
}
/*
Time in milliseconds the scrolling is disabled,
in most cases this is equal to the time the animation takes
*/
setTimeout(function() {
//Unset scroll positions
currentScroll = [];
//Unset dates
currentDate = [];
//Enable scrolling
unfreeze();
/*
Wait 100ms before enabling the direction function again
(to prevent a loop from occuring).
*/
setTimeout(function() {
preventLoop = true;
}, 100);
}, 2000);
}
}
}
$(window).on("scroll", scroll);
})();
Helper functions used in above implementations:
//Source: https://github.com/seahorsepip/jPopup
function freeze(top) {
if(window.innerWidth > document.documentElement.clientWidth) {
$("html").css("overflow-y", "scroll");
}
$("html").css({"width": "100%", "height": "100%", "position": "fixed", "top": -top});
}
function unfreeze() {
$("html").css("position", "static");
$("html, body").scrollTop(-parseInt($("html").css("top")));
$("html").css({"position": "", "width": "", "height": "", "top": "", "overflow-y": ""});
}
function scrollTop() {
return $("html").scrollTop() ? $("html").scrollTop() : $("body").scrollTop();
}
function scrollHeight() {
return $("html")[0].scrollHeight ? $("html")[0].scrollHeight : $("body")[0].scrollHeight;
}
Just had a look at scrollify mentioned in the comments, it's 10kb and needs to hook at every simple event: touch, mouse scroll, keyboard buttons etc.
That doesn't seem very future proof, who know what possible user interaction can cause a scroll in the future?
The onscroll event on the other hand will always be triggered when the page scrolls, so let's just hook the animation code on that without worrying about any input device interaction.
As #seahorsepip states, it is not generally possible to know where a scroll will end up without adding custom behavior with JavaScript. The MDN docs do not list any way to access queued scroll events: https://developer.mozilla.org/en-US/docs/Web/Events/scroll
I found this information helpful:
Normalizing mousewheel speed across browsers
It highlights the difficulty of knowing where the page will go based on user input. My suggestion is to trigger a scroll to Y event when the code predicts the threshold is reached. In your example, if the scroll has moved the page 800 of 1000 pixels in a time window of 250ms, then set the scroll to that 1000 pixel mark and cut off the scroll for 500ms.
https://developer.mozilla.org/en-US/docs/Web/API/window/scrollTo
i'm not pretty sure if i've got what you're looking for. I've had project once, where i had to control the scrolling. Back then i've overwritten the default scroll event, after that you can set a custom distance for "one" scroll. Additionally added jQuery animations to scroll to a specific position.
Here you can take a look: http://c-k.co/zw1/
If that's what you're looking for you can contact me, and i'll see how much i still understand of my own thingy there
is easy to use event listener to do it. Here is a React example:
/**
* scroll promise
*/
const scrollPromiseCallback = useCallback((func:Function) => {
return new Promise((resolve, reject) => {
func(resolve, reject)
})
}, [])
/**
* scroll callback
*/
const scrollCallback = useCallback((scrollContainer, onScrollEnd, resolve) => {
/** 防抖时间 */
const debounceTime = 200
/** 防抖计时器 */
let timer = null
const listener = () => {
if (timer) {
clearTimeout(timer)
}
timer = setTimeout(() => {
scrollContainer.removeEventListener('scroll', listener)
resolve(true)
onScrollEnd?.()
}, debounceTime)
}
scrollContainer.addEventListener('scroll', listener)
}, [])
const scrollTo = useCallback((props:IUseScrollToProps) => {
return scrollPromiseCallback((resolve, reject) => {
const {
scrollContainer = window, top = 0, left = 0, behavior = 'auto',
} = props
scrollCallback(scrollContainer, props?.onScrollEnd, resolve)
scrollContainer.scrollTo({
top,
left,
behavior,
})
})
}, [scrollCallback, scrollPromiseCallback])
i'm trying to change position of a child element(with varying height based on text) using range input,i would like to stop applying top position once the child div touches the bottom of the parent having fixed height.
$('#change_position').on('input', function () {
var val = +$(this).val(),
ScrSize = parseInt($('.screen').css('height')),
Stop = $('.screentip').offset().top,
h = parseInt($('.screentip').css('height')),
tofsset = Stop - h;
if (tofsset < ScrSize) {
$('.screentip').css('top', val + "%");
}
});
The height you are expecting jQuery to return is actually a string with the ending "px". You can use the function .height(). This will return you the height of the element as integer. I have tried a slightly modiefied version of your code:
$('#input').on('input', function () {
var val = parseInt($(this).val()),
ScrSize = parseInt($('#container').height()),
TxtSize = parseInt($("#text").height()),
Stop = ScrSize - TxtSize,
valInPixel = ScrSize * val / 100;
if (valInPixel < Stop) {
$('#text').css('top', val + "%");
}
else
{
$("#text").css("top", Stop + "px");
}
});
The else part will position your element to the bottom, if the number exceeds the frame. You may also have to be aware of padding and margin. This could also lead to mispositioning.
Hope this helps.
I am trying to execute some js code, right now they are replaced by alerts, when the scroll-bar has moved from the top to any other height.
So when the user scrolls for the first-time, the alert "scrolled" will fire.
and if the user scrolls back to the top, it resets and fires an alert "back at top".
I tried doing this with scrollTop, scrollHeight, and clientHeight, but it doesn't seem to fire the alert on scroll.
I'm not trying to fire the alert everytime the user scrolls, just on the first scroll.
But it resets and a new alert is fired if the user scrolls-back to the top.
So if they scroll from top to X, alert "scrolled" fires.
If they scroll from X to Y, nothing happens.
If the scroll from X or Y to top, "back at top" fires.
And then if the scroll from top to X or Y, it has reset and the alert "scrolled" fires (again).
Here is my code:
var body = $('body');
var scrollTop = body.scrollTop;
var difference = body.scrollHeight - body.clientHeight;
var percentScrolled = (scrollTop/difference)*100;
if(percentScrolled > 0){
alert("scrolled!");
}
Update:
I now have this working thanks to one of the comments, it fires the "back to top" alert when scrolled back to the top, but fires the alert "scrolled" on every scroll.
How can I get the "scrolled" alert to fire only when the scroll-bar moves from the top to any other location besides the top?
Here is the code:
window.onscroll = function () {
var doc = document.body,
scrollPosition = doc.scrollTop,
pageSize = (doc.scrollHeight - doc.clientHeight),
percentageScrolled = Math.floor((scrollPosition / pageSize) * 100);
if(percentageScrolled == 0){
alert("back at top");
}
else if(percentageScrolled > 0){
alert("scrolled");
}
};
Exmaple of using javascript to automaticly going back to the top after user scrolls x percent. And as noidea3p5 asked, what is it exactly you are trying to do..
var AllowedPercentageToScroll = 20;
window.onscroll = function () {
var doc = document.body,
scrollPosition = doc.scrollTop,
pageSize = (doc.scrollHeight - doc.clientHeight),
percentageScrolled = Math.floor((scrollPosition / pageSize) * 100);
if(percentageScrolled > AllowedPercentageToScroll){
window.scrollTo(0,0); // back to top
}
else if(percentageScrolled > 0){ // if user starts to scroll it will trigger
//do whatever you like, dont recommend alert though
}
};
Edit:
Shows status if at the top, and shows scrolling activity when starting to scroll
window.onscroll = function () {
var doc = document.body,
scrollPosition = doc.scrollTop,
pageSize = (doc.scrollHeight - doc.clientHeight),
percentageScrolled = Math.floor((scrollPosition / pageSize) * 100);
if(percentageScrolled == 0){
document.getElementById("status").innerHTML = "Your at the top";
}
else if(percentageScrolled > 1){
document.getElementById("status").innerHTML = percentageScrolled + "%";
}
};
</script>
<body>
<div style="width: 100%; position: fixed; top:0px; background-color:#c0c0c0;">
Scroll Position: <span id="status">0%</span>
</div>
Not sure what you are trying to do but it sounds like you may want some kind of flag:
var body = $('body');
var scrollTop = body.scrollTop;
var difference = body.scrollHeight - body.clientHeight;
var percentScrolled = (scrollTop/difference)*100;
if(percentScrolled > 0 && this.leftzero === undefined){
this.leftzero = true;
alert("scrolled!");
}
I'm developing an html page that is quite long and the design has blocks on content vertically like pages. What I want to do is when the user scrolls down the page to "snap" to a point that each page is placed correctly in centre of screen if the position of the user is within a small distance of the correct position.
We're using jquery for other things on the page so happy to use that if it has something relevant.
Any advise is of course much appreciated.
Not tested this but it should work. Refer to the comments for an explanation of how it works.
I disable the point after it has been snapped so that it isn't repeatedly snapped when attempting to scroll away from it. The leniancy variable is both the distance from the point the user must scroll before it becomes active again and the distance before a point is snapped.
var points = [250, 675, 1225, $("#someDiv")]; // y coordinates or jQuery objects you want to centre against.
var disabledPoints = []; // Points that you won't snap to (leave empty) this allows user to scroll from a point
var wMid = ($(window).height() / 2); // Pixels to centre of window
var leniancy = 100; // Number of pixels ether side of a point before it is snapped
$.each(points, function(key, value) { // Loop through points
if (value instanceof jQuery) { // If value is a jQuery object
function setObjectPos(){
var offset = value.offset();
var centerPoint = offset.top + (value.height() /2); // Calculate object centre relative to document
value.data('centerPoint', centerPoint); // Store it for later
});
value.bind('DOMSubtreeModified', setObjectPos); // If div changes update center position.
}
}
$(window).resize(function () { // If user resizes window update window mid-point variable
wMid = ($(window).height() / 2);
});
$(window).scroll(function () {
var centerPos = $(window).scrollTop() + wMid; // Position of screen center relative to document
$.each(points, function(key, value) { // Loop through points
if (value instanceof jQuery) {
value = value.data('centerPoint');
}
var offset = value - centerPos;
if(checkDistance(offset, leniancy)) {
snapToPoint(key); // Success! snap that point
return false; // Kill the loop
}
});
$.each(disabledPoints, function(key, value) { // Loop through disabled points
if (value instanceof jQuery) {
value = value.data('centerPoint');
}
var offset = value - centerPos;
if(!checkDistance(offset, leniancy)) {
enablePoint(key); // Success! enable that point
}
});
});
function checkDistance(offset, margin) {
if (offset > 0) {
if (offset <= margin) {
return true;
}
} else {
if (offset >= (margin * -1)) {
return true;
}
}
return false;
}
function snapToPoint(index) {
var offset = (points[index] instanceof jQuery) ? points[index].data('centerPoint') - wMid : points[index] - wMid;
$(window).scrollTop(offset);
var point = points.splice(index, 1);
disabledPoints.push(point[0]);
}
function enablePoint(index) {
var point = disabledPoints.splice(index, 1);
points.push(point[0]);
}
The same question is answered in jQUery but I'm looking for solution without jQuery.
How do you know the scroll bar has reached bottom of a page
I would like to know how I can determine whether vertical scrollbar has reached the bottom of the web page.
I am using Firefox3.6
I wrote simple Javascript loop to scroll down by 200 pixel and when the scroll bar reached the bottom of the page, I want to stop the loop.
The problem is scrollHeight() is returning 1989.
And inside loop scrollTop is incremented by 200 per iteration.
200 ==> 400 ==> 600 .... 1715
And from 1715, it won't increment so this loop continues forever.
Looks like scrollHeight() and scrollTop() is not right way to compare in order to determine the actual position of scrollbar? How can I know when the loop should stop?
code:
var curWindow = selenium.browserbot.getCurrentWindow();
var scrollTop = curWindow.document.body.scrollTop;
alert('scrollHeight==>' + curWindow.document.body.scrollHeight);
while(curWindow.document.body.scrollHeight > curWindow.document.body.scrollTop) {
scrollTop = curWindow.document.body.scrollTop;
if(scrollTop == 0) {
if(window.pageYOffset) { //firefox
alert('firefox');
scrollTop = window.pageYOffset;
}
else { //IE
alert('IE');
scrollTop = (curWindow.document.body.parentElement) ? curWindow.document.body.parentElement.scrollTop : 0;
}
} //end outer if
alert('current scrollTop ==> ' + scrollTop);
alert('take a shot here');
selenium.browserbot.getCurrentWindow().scrollBy(0,200);
} //end while
When you tell an element to scroll, if its scrollTop (or whatever appropriate property) doesn't change, then can't you assume that it has scrolled as far as is capable?
So you can keep track of the old scrollTop, tell it to scroll some, and then check to see if it really did it:
function scroller() {
var old = someElem.scrollTop;
someElem.scrollTop += 200;
if (someElem.scrollTop > old) {
// we still have some scrolling to do...
} else {
// we have reached rock bottom
}
}
I just read through the jQuery source code, and it looks like you'll need the "pageYOffset". Then you can get the window height and document height.
Something like this:
var yLeftToGo = document.height - (window.pageYOffset + window.innerHeight);
If yLeftToGo is 0, then you're at the bottom. At least that's the general idea.
The correct way to check if you reached the bottom of the page is this:
Get document.body.clientHeight = the height of the ACTUAL screen shown
Get document.body.offsetHeight or document.body.scrollHeight = the height of the entire page shown
Check if document.body.scrollTop = document.body.scrollHeight - document.body.clientHeight
If 3 is true, you reached the bottom of the page
function scrollHandler(theElement){
if((theElement.scrollHeight - theElement.scrollTop) + "px" == theElement.style.height)
alert("Bottom");
}
For the HTML element (like div) add the event -- onscroll='scrollHandler(this)'.
Here is some code I've used to power infinite scrolling list views:
var isBelowBuffer = false; // Flag to prevent actions from firing multiple times
$(window).scroll(function() {
// Anytime user scrolls to the bottom
if (isScrolledToBottom(30) === true) {
if (isBelowBuffer === false) {
// ... do something
}
isBelowBuffer = true;
} else {
isBelowBuffer = false;
}
});
function isScrolledToBottom(buffer) {
var pageHeight = document.body.scrollHeight;
// NOTE: IE and the other browsers handle scrollTop and pageYOffset differently
var pagePosition = document.body.offsetHeight + Math.max(parseInt(document.body.scrollTop), parseInt(window.pageYOffset - 1));
buffer = buffer || 0;
console.log(pagePosition + "px / " + (pageHeight) + "px");
return pagePosition >= (pageHeight - buffer);
}
<span id="add"></add>
<script>
window.onscroll = scroll;
function scroll () {
if (window.pageYOffset + window.innerHeight >= document.body.scrollHeight - 100) {
document.getElementById("add").innerHTML += 'test<br />test<br />test<br />test<br />test<br />';
}
}
</script>
