I have the below script which automatically scrolls right to slide the images. Unfortunately I'm not able to reset the counter.
I've done a condition to see if the scroll is finished, and if it is then reset the width of the scroll, but it seems to not be working. However, if instead of reseting the scroll, I place an alert - then resetting the width works, but scrolling is still not working.
All is working good until the for loop ends and I'm not able to reset the scroll to the beginning.
Here is the script:
<script>
$(function ($) {
$('#headw').on('scroll', function () {
if($(this).scrollLeft() + $(this).innerWidth() >= $(this)[0].scrollWidth) {
// RESET THE COUNTER
$("#headw").animate({
scrollLeft: "+="+width+"px",
}, 3000);
}
else if($(this).scrollLeft() === 0) {
// Remove this part if you don't want your messages hidden again
}
else {
}
})
});
function doItAll() {
// put state variables other than the actual loop control here
function doTheLoop() {
var i;
var count;
var total = <?php echo $row; ?>;
var tx = total + 1;
for (i = 0; i < total; i++) {
var width = $(".divisorx").outerWidth();
count = count + width;
$("#headw").animate({
scrollLeft: "+="+width+"px",
}, 3000);
}
return(false); // done running the loop
}
while (doTheLoop()) {}
// do some things after the loop
}
doItAll();
</script>

So here is the thing, I have a sidebar that has big height due the lots of navigation links. And I'm using jQuery nicescroll plugin to make it look fine. In the sidebar I also have h3 tag which makes a random effect of showing letters (see the code) every 4 seconds. So, when it's on - scroll is not working at all for these 4 seconds and you can't do any scrolling. I tried to use $("#sidebar").getNiceScroll().resize() but it doesn't work either. Is there any way to make it work?
<div id="sidebar">
<h3 id="output">Random</h3>
</div>
//Calling for nicescroll function for my sidebar
$(function(){
$("#sidebar").niceScroll({ cursorcolor:"#66aee9", cursorfixedheight: 400 });
})
//Random effect for my h3 tag
setInterval(function(){
$(document).ready(function(){
var theLetters = "abcdefghijklmnopqrstuvwxyz#%&^+=-"; //You can customize what letters it will cycle through
var ctnt = "Random"; // Your text goes here
var speed = 50; // ms per frame
var increment = 8; // frames per step. Must be >2
var clen = ctnt.length;
var si = 0;
var stri = 0;
var block = "";
var fixed = "";
//Call self x times, whole function wrapped in setTimeout
(function rustle (i) {
setTimeout(function () {
if (--i){rustle(i);}
nextFrame(i);
si = si + 1;
}, speed);
})(clen*increment+1);
function nextFrame(pos){
for (var i=0; i<clen-stri; i++) {
//Random number
var num = Math.floor(theLetters.length * Math.random());
//Get random letter
var letter = theLetters.charAt(num);
block = block + letter;
}
if (si == (increment-1)){
stri++;
}
if (si == increment){
// Add a letter;
// every speed*10 ms
fixed = fixed + ctnt.charAt(stri - 1);
si = 0;
}
$("#output").html(fixed + block);
block = "";
}
});
}, 4000);
I change to rows and check it in jsfiddle, looks like working scroll fine.
Before:
setInterval(function(){
$(document).ready(function(){
...
});
}, 4000);
After:
$(document).ready(function(){
setInterval(function(){
...
}, 4000);
});
Right now when you click inside the div, the counter decreases by 1. How do I make it stop at 0?
Also when it reaches 0 how can I add a class?
I want the overlay to be enabled once the click counter reaches 0.
If there is a better way to disable the div box1 after the clicks reach 0. We can try it that way.
$( function() {
$('.box').click( function() {
var num = $(this).find('.num');
num.text( parseInt(num.text()) - 1 );
});
});
fiddle
Rather than searching DOM and parsing HTML on each click, I'd cache both element and its value:
var $box = $('#box1'),
$num = $box.find('.num'),
limit = $num.text();
$box.click(function() {
$num.text(--limit);
if (limit === 0) {
$('.overlay').show();
}
});
Demo.
This should do it:
$('.box').click( function() {
var num = $(this).find('.num');
val = parseInt(num.text()) - 1;
if (val > 0){
num.text(val - 1);
} else {
$(".overlay").show();
// add your class here.
}
num.text( val );
});
Updated Fiddle
I have almost finished this slider, but I don't know how to implement the functionality for next() and prev(). How can I implement these functions?
http://jsfiddle.net/M4t4L/11/
$(function () {
var container = $("#scene"),
i = 0,
count = container.find("li").length,
j = container.find("li").length - 1,
isAnimating = false;
container.find("li:first").css({
"width": "100%"
});
$("#trigger").click(function (e) {
if (!isAnimating) {
isAnimating = true;
e.preventDefault(e);
i++; if (i >= count) { i = 0; }
j++; if (j >= count) { j = 0; }
container.find("li")
.finish()
.removeClass('active')
.last()
.width(0)
.addClass("active")
.animate({
"width": "100%"
}, 800,
function () {
container.find("li").first().appendTo(container);
isAnimating = false;
});
}
});
});
The problem is that when I implement these functions and press the next or prev. Displays the last slide on one second, and then switches to the desired
http://jsfiddle.net/M4t4L/9
If you want to get a Next or Prev function running, you want to take control of the number of the slider where you are. I'm afraid you will have to play around with your i/j and make the position go in both directions.
Right now you count up your i and j, where you might want to go is to have a position var and an array of slider objects, then the click only would have to call for the next/prev object to be loaded and the animation can begin.
Something like this maybe..
var pos = 0;
var container = $('#scene').find('li');
$('.back').click(function() {
pos = pos - 1;
moveIt(pos);
});
$('.forth').click(function() {
pos = pos +1;
moveIt(pos);
});
function moveIt(pos) {
container[pos]... // Your animation goes here
}
I'm using a script that animates on click left or right to the next div. It currently works fine but I'm looking to add two features to it. I need it to repeat back to the first slide if it is clicked passed the last slide and go to the last slide if click back from the first slide. Also, I'm interested in getting this to autostart on page load.
I've tried wrapping the clicks in a function and setting a setTimeout but it didn't seem to work. The animation is currently using CSS.
Here's the current JS:
<script>
jQuery(document).ready(function() {
var boxes = jQuery(".box").get(),
current = 0;
jQuery('.right').click(function () {
if (current == (-boxes.length + 1)){
} else {
current--;
updateBoxes();
}
console.log(-boxes.length + 1);
console.log(current);
});
jQuery('.left').click(function () {
if (current === 0){
} else{
current++;
updateBoxes();
}
});
function updateBoxes() {
for (var i = current; i < (boxes.length + current); i++) {
boxes[i - current].style.left = (i * 100 + 50) + "%";
}
}
});
</script>
Let me know if I need a jsfiddle for a better representation. So far, I think the code is pretty straightforward to animate on click.
Thanks.
Try
jQuery(document).ready(function () {
var boxes = jQuery(".box").get(),
current = 0,
timer;
jQuery('.right').click(function () {
if (current == (-boxes.length + 1)) {
current = 0;
} else {
current--;
}
updateBoxes();
}).click(); //initialize the view
jQuery('.left').click(function () {
if (current === 0) {
current = -boxes.length + 1;
} else {
current++;
}
updateBoxes();
});
function updateBoxes() {
//custom implementation for testing
console.log('show', current)
$(boxes).hide().eq(-current).show();
autoPlay();
}
function autoPlay() {
clearTimeout(timer);
//auto play
timer = setTimeout(function () {
jQuery('.right').click();
}, 2500)
}
});
Demo: Fiddle
Here's an example based on my comment (mostly pseudocode):
$(function(){
var boxes = $('.box'),
current = 0,
timer;
// Handler responsible for animation, either from clicking or Interval
function animation(direction){
if (direction === 1) {
// Set animation properties to animate forward
} else {
// Set animation properties to animate backwards
}
if (current === 0 || current === boxes.length) {
// Adjust for first/last
}
// Handle animation here
}
// Sets/Clears interval
// Useful if you want to reset the timer when a user clicks forward/back (or "pause")
function setAutoSlider(set, duration) {
var dur = duration || 2000;
if (set === 1) {
timer = setInterval(function(){
animation(1);
}, dur);
} else {
clearInterval(timer)
}
}
// Bind click events on arrows
// We use jQuery's event binding to pass the data 0 or 1 to our handler
$('.right').on('click', 1, function(e){animation(e.data)});
$('.left').on('click', 0, function(e){animation(e.data)});
// Kick off animated slider
setAutoSlider(1, 2000);
Have fun! If you have any questions, feel free to ask!
I'm looking to build a very simple whack a mole-esque game in javascript. Right now I know how to do everything else except the scoring. My current animation code is as follows
<script language="JavaScript"
type="text/javascript">
var urls;
function animate(pos) {
pos %= urls.length;
document.images["animation"].src=urls[pos];
window.setTimeout("animate(" + (pos + 1) + ");",
500);
}
window.onload = function() {
urls = new Array(
"Frame1.jpg","Frame2.jpg"
);
animate(0);
}
</script>
So far it all works, the first frame is the hole and the second is the groundhog/mole out of the hole. I need to count the clicks on the second frame but I can't figure out how to incorporate a counter. Help? (Sorry if the code doesn't show up correctly, first time using this site)
Here is an example that counts clicks on the flashing animation: http://jsfiddle.net/maniator/TQqJ8/
JS:
function animate(pos) {
pos %= urls.length;
var animation = document.getElementById('animation');
var counter = document.getElementById('counter');
animation.src = urls[pos];
animation.onclick = function() {
counter.innerHTML = parseInt(counter.innerHTML) + 1;
}
setTimeout(function() {
animate(++pos);
}, 500);
}
UPDATE:
Here is a fiddle that only detects click on one of the images: http://jsfiddle.net/maniator/TQqJ8/8/
