I have some problem with this code, in this case i set div as a button, when I click the button everything is working as expected but when I want to stop animation with clearInterval it doesn’t work, just keeps looping... What I am doing wrong?
var timeout;
var d1=$(".drum1");
function dani1(){
d1.animate({height:'150px', width:'150px', opacity:'0.4'},"slow");
d1.animate({height:'100px', width:'100px',opacity:'0.8'},"fast");
}
d1.click(function(){
if (!timeout){
timeout = setInterval(dani1, 200);
} else {
clearInterval(timeout);
timeout = null;
}
});
<div class="drum1" style="background:#98bf21;height:100px;width:100px;position:absolute;">
</div>
You do not need setInterval at all..
var d1 = $(".drum1").data('end', true);
function dani1() {
if (d1.data('end'))
return d1.stop(true, true);
d1.animate({
height: '150px',
width: '150px',
opacity: '0.4'
}, "slow")
.animate({
height: '100px',
width: '100px',
opacity: '0.8'
}, "fast", dani1);
}
d1.click(function() {
if (!d1.data('end'))
d1.data('end', true);
else {
d1.data('end', false);
dani1();
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="drum1" style="background:#98bf21;height:100px;width:100px;position:absolute;"></div>
The problem is your usage of setInterval(), it will queue a lot of animations every 200ms so even after clearing the interval there are a lot of animations present in the animation queue.
One easy solution is to clear the animation queue also
var timeout;
var d1 = $(".drum1");
function dani1() {
d1.animate({
height: '150px',
width: '150px',
opacity: '0.4'
}, "slow");
d1.animate({
height: '100px',
width: '100px',
opacity: '0.8'
}, "fast");
}
d1.click(function() {
if (!timeout) {
timeout = setInterval(dani1, 200);
} else {
d1.stop(true, true)
clearInterval(timeout);
timeout = null;
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="drum1" style="background:#98bf21;height:100px;width:100px;position:absolute;"></div>
Without interval
var play;
var d1 = $(".drum1");
function dani1() {
d1.animate({
height: '150px',
width: '150px',
opacity: '0.4'
}, "slow");
d1.animate({
height: '100px',
width: '100px',
opacity: '0.8'
}, "fast");
return d1.promise();
}
d1.click(function() {
if (play) {
play = false;
d1.stop(true, true)
} else {
play = true;
anim();
}
function anim() {
dani1().done(function() {
if (play === true) {
anim();
}
})
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="drum1" style="background:#98bf21;height:100px;width:100px;position:absolute;"></div>
With below script written for click event.
I want to use Same code(selectors) for Mouse in, mouse out event
$('.tools_collapsed').wrap('<div class="newparent" />');
var speed = 600;
$('.tools_collapsed').show().css({ right: '-250px' }).hide();
$('.tools_collapsed .collapse_btn').hide();
$('.tools_expand').click(function () {
$('.tools_collapsed').show().animate({ right: '0' }, { duration: speed });
$('.tools_collapsed .collapse_btn').show();
})
$('a.collapsed').click(function () {
$('.tools_expand').css({ display: 'none' });
$('.tools_collapsed').animate({ right: '-250', easing: 'easeOutQuad' }, 400, function () {
$('.tools_collapsed .collapse_btn').css("display", "none");
$('.tools_expand').show("normal");
});
})
}
Try this approach...
function yourFunction(){
//your code here
}
$("#yourSelector").hover(
yourFunction(),
yourFunction()
);
You can try this:
$('.tools_collapsed').wrap('<div class="newparent" />');
var speed = 600;
$('.tools_collapsed').show().css({ right: '-250px' }).hide();
$('.tools_collapsed .collapse_btn').hide();
$('.tools_expand').on( "mouseenter",function () {
$('.tools_collapsed').show().animate({ right: '0' }, { duration: speed });
$('.tools_collapsed .collapse_btn').show();
})
$('.tools_expand').on( "mouseout", function () { // changed from "a.collapsed"
$('.tools_expand').css({ display: 'none' });
$('.tools_collapsed').animate({ right: '-250', easing: 'easeOutQuad' }, 400, function () {
$('.tools_collapsed .collapse_btn').css("display", "none");
$('.tools_expand').show("normal");
});
})
How can I change this script from jQuery to JavaScript? I have little experience with JavaScript and I don't know how to change it myself.
Script:
var rotate = function() {$("#Top")
.delay(1000).queue(function() {
$(this).css({
"background-color": "red"
});
$(this).dequeue();
})
.delay(3000).queue(function() {
$(this).css({
"background-color": "green"
});
$(this).dequeue();
})
.delay(500).queue(function(next) {
$(this).css({
"background-color": "blue"
});
$(this).dequeue();
next();
})
.queue(rotate);
};
rotate();
Html
<div id="Top"></div>

John Resig is the guy who wrote jQuery and here is a blurb about How JavaScript Timers Work.
I know it is not perfect and could use setInterval() and clearInterval() to be more efficient, but this is a start DEMO
var rotate = function () {
var el = document.getElementById('Top');
setTimeout(function () {
el.style.backgroundColor = 'red';
setTimeout(function () {
el.style.backgroundColor = 'green';
setTimeout(function () {
el.style.backgroundColor = 'blue';
rotate();
}, 500);
}, 3000);
}, 1000);
}
Update: Added an array to reference timeout IDs to ensure that duplicates are not created in case time gets out of sync.
var rotate = function () {
var el = document.getElementById('Top');
var timers = new Array(3);
function red(el) {
el.style.backgroundColor = 'red';
timers[0] = setTimeout(function () { green(el); }, 1000);
clearTimeout(timers[2]);
}
function green(el) {
el.style.backgroundColor = 'green';
timers[1] = setTimeout(function () { blue(el); }, 3000);
clearTimeout(timers[0]);
}
function blue(el) {
el.style.backgroundColor = 'blue';
timers[2] = setTimeout(function () { red(el); }, 500);
clearTimeout(timers[1]);
}
red(el);
};
rotate();
The title of your post should be: "How can I change this from jQuery to CSS" ;-)

If you want to have smooth transition between your background color just omit the steps(1) in the animation shorthand property.

I am trying to impliment tweet scroller on http://www.hubspot.com/
which is i guess using tweet-scroller from http://code.divshot.com/tweetscroller/
but this link is broken as demo is not working.
i looked for alternative.
I found http://jsfiddle.net/doktormolle/4c5tt/
HTML:
<ul class="slide">

ul.slide{margin:0;
padding:0;
height:80px;
list-style-type:none;}
ul.slide li{float:left;
list-style-type:none;}
ul.slide img{border:1px solid silver;
height:80px;}
JS:
//Plugin start
(function ($) {
var methods = {
init: function (options) {
return this.each(function () {
var _this = $(this);
_this.data('marquee', options);
var _li = $('>li', _this);
_this.wrap('<div class="slide_container"></div>')
.height(_this.height())
.hover(function () {
if ($(this).data('marquee').stop) {
$(this).stop(true, false);
}
},
function () {
if ($(this).data('marquee').stop) {
$(this).marquee('slide');
}
})
.parent()
.css({
position: 'relative',
overflow: 'hidden',
'height': $('>li', _this).height()
})
.find('>ul')
.css({
width: screen.width * 2,
position: 'absolute'
});
for (var i = 0; i < Math.ceil((screen.width * 3) / _this.width()); ++i) {
_this.append(_li.clone());
}
_this.marquee('slide');
});
},
slide: function () {
var $this = this;
$this.animate({
'left': $('>li', $this).width() * -1
},
$this.data('marquee').duration,
'swing',
function () {
$this.css('left', 0).append($('>li:first', $this));
$this.delay($this.data('marquee').delay).marquee('slide');
}
);
}
};
$.fn.marquee = function (m) {
var settings = {
'delay': 2000,
'duration': 900,
'stop': true
};
if (typeof m === 'object' || !m) {
if (m) {
$.extend(settings, m);
}
return methods.init.apply(this, [settings]);
} else {
return methods[m].apply(this);
}
};
})(jQuery);
//Plugin end
//call
$(document).ready(
function () {
$('.slide').marquee({
delay: 3000
});
}
);
which works fine with little modification i did
http://jsfiddle.net/3pZwR/1/
only problem is it stops after each div is scrolled.
I want it to be infinite scroll like effect without getting it stopped. like on hubspot.
You should use another JQuery Easing method instead of "swing".
Have a look at the Easings on the JQuery website: http://api.jqueryui.com/easings/
I'm trying to find a very simple and smooth, lightweight javascript or jquery marquee. I already tried silk marquee or something, but it wouldn't work with the application I was using. So the simpler and shorter, the better - and easier to debug. Does anybody know of a easy to implement javascript replacement for the marquee?

<h1>Hello World!</h1>
<h2>I'll marquee twice</h2>
<h3>I go fast!</h3>
<h4>Left to right</h4>
<h5>I'll defer that question</h5>
Jquery code
(function($) {
$.fn.textWidth = function(){
var calc = '<span style="display:none">' + $(this).text() + '</span>';
$('body').append(calc);
var width = $('body').find('span:last').width();

'text-indent' : that.css('text-indent'),
'overflow' : that.css('overflow'),
'white-space' : that.css('white-space')
},
marqueeCss = {
'text-indent' : width,
'overflow' : 'hidden',
'white-space' : 'nowrap'
},
args = $.extend(true, { count: -1, speed: 1e1, leftToRight: false }, args),
i = 0,
stop = textWidth*-1,
dfd = $.Deferred();
function go() {
if(!that.length) return dfd.reject();
if(width == stop) {

}
}
that.css('text-indent', width + 'px');
if(args.leftToRight) {

} else {
width--;
}
setTimeout(go, args.speed);
};
if(args.leftToRight) {

$('h1').marquee();
$('h2').marquee({ count: 2 });

$('h4').marquee({ leftToRight: true });
$('h5').marquee({ count: 1, speed: 2 }).done(function() { $('h5').css('color', '#f00'); })
I've made very simple function for marquee. See: http://jsfiddle.net/vivekw/pHNpk/2/
It pauses on mouseover & resumes on mouseleave. Speed can be varied. Easy to understand.
function marquee(a, b) {
var width = b.width();
var start_pos = a.width();
var end_pos = -width;
function scroll() {
if (b.position().left <= -width) {
b.css('left', start_pos);
scroll();
}
else {
time = (parseInt(b.position().left, 10) - end_pos) *
(10000 / (start_pos - end_pos)); // Increase or decrease speed by changing value 10000
b.animate({
'left': -width
}, time, 'linear', function() {
scroll();
});
}
}
b.css({
'width': width,
'left': start_pos
});
scroll(a, b);
b.mouseenter(function() { // Remove these lines
b.stop(); //
b.clearQueue(); // if you don't want
}); //
b.mouseleave(function() { // marquee to pause
scroll(a, b); //
}); // on mouse over
}
$(document).ready(function() {
marquee($('#display'), $('#text')); //Enter name of container element & marquee element
});
I just created a simple jQuery plugin for that. Try it ;)
https://github.com/aamirafridi/jQuery.Marquee
The following works:
http://jsfiddle.net/xAGRJ/4/
The problem with your original code was you are calling scrollticker() by passing a string to setInterval, where you should just pass the function name and treat it as a variable:
lefttime = setInterval(scrollticker, 50);
instead of
lefttime = setInterval("scrollticker()", 50);
Why write custom jQuery code for Marquee... just use a plugin for jQuery - marquee() and use it like in the example below:
First include :
<script type='text/javascript' src='//cdn.jsdelivr.net/jquery.marquee/1.3.1/jquery.marquee.min.js'></script>
and then:
//proporcional speed counter (for responsive/fluid use)
var widths = $('.marquee').width()
var duration = widths * 7;
$('.marquee').marquee({
//speed in milliseconds of the marquee
duration: duration, // for responsive/fluid use
//duration: 8000, // for fixed container
//gap in pixels between the tickers
gap: $('.marquee').width(),
//time in milliseconds before the marquee will start animating
delayBeforeStart: 0,
//'left' or 'right'
direction: 'left',
//true or false - should the marquee be duplicated to show an effect of continues flow
duplicated: true
});
If you can make it simpler and better I dare you all people :). Don't make your life more difficult than it should be. More about this plugin and its functionalities at: http://aamirafridi.com/jquery/jquery-marquee-plugin
I made my own version, based in the code presented above by #Tats_innit .
The difference is the pause function. Works a little better in that aspect.
(function ($) {
var timeVar, width=0;
$.fn.textWidth = function () {
var calc = '<span style="display:none">' + $(this).text() + '</span>';
$('body').append(calc);
var width = $('body').find('span:last').width();
$('body').find('span:last').remove();
return width;
};
$.fn.marquee = function (args) {
var that = $(this);
if (width == 0) { width = that.width(); };
var textWidth = that.textWidth(), offset = that.width(), i = 0, stop = textWidth * -1, dfd = $.Deferred(),
css = {
'text-indent': that.css('text-indent'),
'overflow': that.css('overflow'),
'white-space': that.css('white-space')
},
marqueeCss = {
'text-indent': width,
'overflow': 'hidden',
'white-space': 'nowrap'
},
args = $.extend(true, { count: -1, speed: 1e1, leftToRight: false, pause: false }, args);
function go() {
if (!that.length) return dfd.reject();
if (width <= stop) {
i++;
if (i <= args.count) {
that.css(css);
return dfd.resolve();
}
if (args.leftToRight) {
width = textWidth * -1;
} else {
width = offset;
}
}
that.css('text-indent', width + 'px');
if (args.leftToRight) {
width++;
} else {
width=width-2;
}
if (args.pause == false) { timeVar = setTimeout(function () { go() }, args.speed); };
if (args.pause == true) { clearTimeout(timeVar); };
};
if (args.leftToRight) {
width = textWidth * -1;
width++;
stop = offset;
} else {
width--;
}
that.css(marqueeCss);
timeVar = setTimeout(function () { go() }, 100);
return dfd.promise();
};
})(jQuery);
usage:
for start: $('#Text1').marquee()
pause: $('#Text1').marquee({ pause: true })
resume: $('#Text1').marquee({ pause: false })

select: $('.message div'),
clickSelect: '', // selector that on click will redirect user ... (optional)
clickUrl: '' //... to this url. (optional)
}, options);
//Run marque plugin
var windowWidth = $(window).width();
var textWidth = defOptions.select.outerWidth();
var duration = (windowWidth + textWidth) * 1000 / defOptions.speedPixelsInOneSecound;
var startingPosition = (windowWidth + textWidth);
var curentPosition = (windowWidth + textWidth);
var speedProportionToLocation = curentPosition / startingPosition;
defOptions.select.css({'right': -(textWidth)});
defOptions.select.show();
var animation;
function marquee(animation){

if(defOptions.clickSelect != '' && defOptions.clickUrl != ''){
defOptions.clickSelect.click(function(){
window.location.href = defOptions.clickUrl;
});
}
return this;
};
}(jQuery));
// end plugin
Use this custom jQuery plugin as bellow:
//use example
$(window).marque({
speedPixelsInOneSecound: 150, // spped pixels/secound
select: $('.message div'), // select an object on which you want to apply marquee effects.
clickSelect: $('.message'), // select clicable object (optional)
clickUrl: 'services.php' // define redirection url (optional)
});
