Simulating Spinner Number with mousedown

I made a control (numeric spinner up and down), to work in a table:
JSFIDDLE: http://jsfiddle.net/Leandro1981/wn8vd/1/
and I want simulate the "mousedown, increment while mouse button is helding" but I can't do it. I tried to mix it with the following and functional script:
JSFIDDLE: http://jsfiddle.net/Leandro1981/kKW85/
but I couldn't make it.
My last attempt here:
http://jsfiddle.net/Leandro1981/S8Zt9/1/
Maybe the wrong is the
timeout = setInterval(function () {
But I couldn't figure out. I'm using bootstrap 3, so I can't use some JQuery UI plugins...
Any help will be preciated!
Please comment below if you have any question, comment or anything to improve this question, and sorry for my english :)
Please be free to use my code/control in any way.
Thanks and kind regards

Write a factory to set up each control so you get a closure over the variables, now it's just a matter of being able to make it work given the relevant elements. For this, you'll need to
Listen for mousedown on the up and down nodes to set off the changes
Start a timeout loop to keep doing your change
Listen for mouseup on window to ensure you cancel the timeout loop (you may also want to listen for mouseout/loss of focus)
So all together,
function spinFactory(node, up, down) { // I wrote this vanilla :D
var spinning, delta;
window.addEventListener('mouseup', stopSpin);
function spin() {
node.value = +node.value + delta;
spinning = setTimeout(spin, 500);
}
function stopSpin() { // maybe also invoke this on mouseout/loss of focus
window.clearTimeout(spinning);
delta = 0;
}
up.addEventListener('mousedown', function spinUp() {
delta = 1;
spin();
});
down.addEventListener('mousedown', function spinDown() {
delta = -1;
spin();
});
}
// apply to your control, used a bit of jQuery to make life easier
$('.PNET-spinner').each(function () {
spinFactory(
this.getElementsByTagName('input')[0],
$(this).find('.btn:first-of-type')[0],
$(this).find('.btn:last-of-type')[0]
);
});
DEMO

I have updated the Fiddle here ... Please check this and it might helps you..
Script
$('.PNET-spinner .btn:first-of-type').on('mousedown', function (e) {
var timer, proxy = this;
timer = setInterval(function () {
increment(proxy);
}, 200);
$(document).one("mouseup", function () {
increment(proxy);
if (timer) clearInterval(timer);
});
});
$('.PNET-spinner .btn:last-of-type').on('mousedown', function () {
var timer, proxy = this;
timer = setInterval(function () {
decrement(proxy);
}, 200);
$(document).one("mouseup", function () {
decrement(proxy);
if (timer) clearInterval(timer);
});
});
function increment(proxy) {
var numupdown = $('.PNET-spinner input', $(proxy).closest("tr"));
var inputValue = parseInt($(numupdown).val(), 10);
inputValue++;
$(numupdown).val(inputValue);
}
function decrement(proxy) {
var numupdown = $('.PNET-spinner input', $(proxy).closest("tr"));
var inputValue = parseInt($(numupdown).val(), 10);
if (inputValue > 1) {
inputValue--;
$(numupdown).val(inputValue);
}
}

You simply need to take care of two things. First, your function to increment and decrement the value in the textbox should be called again and again till user do mouseout or mouseup. Second, make surethis has the right value in var numupdown = $('.PNET-spinner input', $(this).closest("tr"));
Following code shows how to do it for the increment button. Similar thing, you can implement for decrement button.
var timeout;
var inc = function () {
var myThis = this;
var numupdown = $('.PNET-spinner input', $(this).closest("tr"));
var inputValue = parseInt($(numupdown).val(), 10);
inputValue++;
console.log(inputValue);
$(numupdown).val(inputValue);
clearTimeout(timeout);
timeout = setTimeout(function(){
//http://stackoverflow.com/questions/3630054/how-do-i-pass-the-this-context-to-a-function
inc.apply(myThis, arguments);
}, 1000);
};
var incStop = function(){
clearTimeout(timeout);
}
$('.PNET-spinner .btn:first-of-type').on('mousedown', inc);
$('.PNET-spinner .btn:first-of-type').on('mouseup', incStop);
$('.PNET-spinner .btn:first-of-type').on('mouseout', incStop);

Start/stop function with setInterval

i've got a simple setInterval function for radio buttons to loop on load.
I would like to add a button, which could start or stop the loop. I've added click function for the function, but don't know how to stop it afterwards.
Here is what i've got so far: jsfiddle
Also, if i click the button more times in a row, loop goes berserker - any help appricieted :)
p.s. I've also checked:
start & stop / pause setInterval with javascript, jQuery and
Javascript loop-problem with setTimeout/setInterval
but i was wondering in the dark on how to use those answers as i'm javascript noob.

Make a reference to your setInterval so you can use clearInterval(yourreference).
To start / stop, you can add an extra boolean variable to toggle start and stop.
var t;
var running = false;
$("#start-stop").click(function(){
clearInterval(t);
running = !running;
if (!running)
return;
t = setInterval(function(){
$('.wrap input')
.eq( ( $('input:checked').index() + 1 ) % 3 )
.prop('checked',true);
},1000);
});
Fiddle

Try
jQuery(function () {
var timer;
$("#start-stop").click(function () {
if (timer) {
clearInterval(timer);
timer = undefined;
} else {
timer = setInterval(function () {
$('.wrap input')
.eq(($('input:checked').index() + 1) % 3)
.prop('checked', true);
}, 1000);
}
});
})
Demo: Fiddle

le solution without clearInterval
jQuery(function () {
var toggle = null;
$("#start-stop").click(function () {
if(toggle == null) {
toggle = false;
setInterval(function () {
if(toggle)
$('.wrap input').eq(($('input:checked').index() + 1) % 3).prop('checked', true);
}, 1000);
}
toggle = !toggle;
});
});

how to stop an Interval function in my jquery plugin

i wrote a jquery plugin to make a div auto scroll,i used function setInterval to make the div stop for a while and then keeps on scroll.
here is the code
(function($){
"use strict";
function scrolltotop(obj,height,speed){
var ch=parseInt($(obj).css("margin-top"))+29;
$(obj).parent().find(".moving").remove();
$(obj).after($(obj).clone().addClass("copy"));
$(obj).addClass("moving").removeClass("copy").animate({
"margin-top":-27
},speed);
loop=setInterval(function(){
ch+=27;
if(ch < height+27){
$(obj).animate({
"margin-top":-ch
},speed,function(){
loop;
})
}else{
clearInterval(loop);
scrolltotop($(obj).next(".copy"),height,speed);
}
},4000)
}
$.fn.extend({
autoscroll: function(options) {
var defaults = {
speed: 1000,
scroller : '#scroller',
scroller_container : '#scroller_container'
}
var options = $.extend(defaults, options);
var height=$(options.scroller).height();
var stop=stopscroll();
//console.log(height)
scrolltotop(options.scroller,height,options.speed);
},
});
}(jQuery));
$("#list2").autoscroll({scroller:"#list2",scroller_container:"#container_2"});
it works well,but idont know how to make the div stop scroll after i init the plugin.

if I understand the problem you want to move the div scroll line by line waiting 4s until you reach the end.
I simplified your scrolltotop function
function scrolltotop(obj,height,speed){
var ch = 0;
var loop = setInterval(function(){
ch+=27;
$('#container_2').animate({
scrollTop: ch
}, speed);
if(ch >= height){
console.log('Out of loop');
clearInterval(loop);
}
},4000);
}
You can see a working example here http://jsfiddle.net/jCw3y/
May be you can adapt my code to use it in your plugin.
(You're using "use strict". Remember to declare javascript variables always. var loop, var ch e.t.c)
To stop manually you can save the intervalId and call clearInterval when you want.
Check this example: http://jsfiddle.net/ccR4t/
And finally, another example with pure jquery. Using animate and stop functions to control all.
(function ($) {
"use strict";
function scrolltotop($container, options) {
$container.animate({
scrollTop: options.scrollerHeight
}, options.speed, function () {
console.log('Animation completed');
});
}
$.fn.extend({
autoscroll: function (options) {
var $me = this;
var defaults = {
speed: 1000,
scroller_container: '#scroller_container',
scroller: '#list2'
}
var options = $.extend(defaults, options);
options.scrollerHeight = $(options.scroller).height();
scrolltotop($me, options);
},
});
}(jQuery));
$("#container_2").autoscroll({
scroller: '#list2',
speed: 10000
});
// stop scroll after 4 sec
setTimeout(function () {
$('#container_2').stop();
alert('scroll manually stopped')
}, 4000);

How to pause slideshow when hovering

How do I add a pause effect when I hover over an image in a jQuery slideshow?
$(document).ready(function () {
slideShow();
});
function slideShow() {
var showing = $('#slideshow .show');
var next = showing.next().length ? showing.next() : showing.parent().children(':first');
var timer;
showing.fadeOut(500, function () {
next.fadeIn(200).addClass('show');
}).removeClass('show');
setTimeout(slideShow, 3000);
}

var hovering = false; //default is not hovering
$("#slideshow").hover(function () { //*replace body with your element
hovering = true; //when hovered, hovering is true
}, function () {
hovering = false; //when un-hovered, hovering is false
slideShow(); //start the process again
});
function slideShow() {
if(!hovering) { //if not hovering, proceed
/* Your code here*/
nextSlide();
setTimeout(slideShow, 1000);
}
}
function nextSlide(){
var showing = $('#slideshow .show');
var next = showing.next().length ? showing.next() : showing.parent().children(':first');
var timer;
showing.fadeOut(500, function () {
next.fadeIn(200).addClass('show');
}).removeClass('show');
}
Demo: http://jsfiddle.net/DerekL/mqEbZ/

Use .delay() that will help.
Description: Set a timer to delay execution of subsequent items in the queue.

I think you need two functions for that ... slideShow() and other one say pauseSlideshow()... now call the slideshow() on mouseout event and on mouseenter call pauseSlideShow()
your code should be something like this
$(document).ready(function(){
$('.slider').mouseout( slideShow());
$('.slider').mouseenter( pauseSlideShow());
});
function slideShow() {
var showing = $('#slideshow .show');
var next = showing.next().length ? showing.next() : showing.parent().children(':first');
var timer;
showing.fadeOut(500, function() { next.fadeIn(200).addClass('show'); }).removeClass('show');
timeOut = setTimeout(slideShow, 3000);
}
function PauseSlideShow() {
window.clearTimeout(timeOut);
}
TRY IT

Working off of Derek's answer, an alternative to hover would be to use mouseenter and mouseleave.
See the working slideshow Jsfiddle: Demo: http://jsfiddle.net/highwayoflife/6kDG7/
var hovering = false;
var slideshow = $("#slideshow");
slideshow.mouseenter(function() {
hovering = true;
}).mouseleave(function() {
hovering = false;
slideShow();
});
function slideShow() {
if (!hovering) {
# Some browsers don't interpret "display:block" as being visible
# If no images are deemed visible, choose the first...
var currentImg = (slideshow.children("img:visible").length) ? slideshow.children("img:visible") : slideshow.children("img:first");
var nextImg = (currentImg.next().length) ? currentImg.next() : slideshow.children("img:first");
currentImg.fadeOut(500, function() {
nextImg.fadeIn(500, function() {
setTimeout(slideShow, 2000);
});
});
}
}
$(document).ready(function() {
slideShow();
});

How to stop click events from queuing up on multiple click?

What I need to achieve is if we click on submit button, there is particular div should show up.
Here is my code:
http://jsfiddle.net/7tn5d/
But if I click on submit button multiple times, the function calls sort of queue up and run one after other.
Is there a way to invalidate other onclicks when current animation is running?
Code:
animating = 0;
doneanim = 0;
$(function () {
$("#submit_tab").click(function (e) {
if (animating == 1) return;
animating = 1;
$("#submit_cont").show("blind", {}, 1000);
animating = 0;
});
});

To prevent it from performing the action multiple times, simple cease the previous animation. So:
$('#submit_cont').stop().show("blind",{},1000);
However, I have noticed that you have attempted to prevent the animation from running, if an animation is already running. Although it takes 1 second or 1000 milliseconds to show the div, the execution of the condition does not pause until the animation is complete. You must define a function to run after the animation is complete, like so:
animating = 0;
doneanim = 0;
$(function () {
$("#submit_tab").click(function (e) {
if (animating == 1) return;
animating = 1;
$("#submit_cont").show("blind", 1000, function() { animation = 0; });
});
});
Hope that helped...

You almost got it right with the semaphore! It's just that, in jQuery's show(), you would have to put the semaphore reset as an argument. Here's the fixed version - http://jsfiddle.net/snikrs/xe5A3/
animating = 0;
doneanim = 0;
$(function () {
$("#submit_tab").click(function (e) {
if (animating == 1) return;
animating = 1;
$("#submit_cont").show("blind", 1000, function() {
animating = 0;
});
});
});

You can use the :animated selector to check:
$(function () {
$("#submit_tab").click(function (e) {
var $cont = $("#submit_cont");
if (!$cont.is(':animated')) {
$cont.show("blind", {}, 1000);
}
});
});
Now if you stick with the external semaphore idea then its better to stick that on the elemnt with .data() instead of using a global variable:
$(function () {
$("#submit_tab").click(function (e) {
var $cont = $('#submit_cont'),
animating = $cont.data('isAnimating');
if (animating) {
return;
} else {
$cont.data('isAnimating', 1);
$("#submit_cont").show("blind", 1000, function() { $cont.data('isAnimating', 0); });
}
});
});

Something like this (see documentation) :)
$("#submit_cont").show("blind", function(){
animating = 0;
});

You can add a $("#submit_cont").clearQueue(); after the animation finished :
$("#submit_tab").click(function (e) {
$("#submit_cont").show("blind", 1000, function() {
$("#submit_cont").clearQueue();
});
});
Updated JSFiddle

I found a different solution for this, which in my opinion looks cleaner:
var tab = $("submit_tag");
tab.on("click", function(){
var cont = $("submit_cont");
var animating = tab.queue("fx").length;
if(animating === 0){
cont.show("blind", {}, 1000);
}
});
