I'm trying to fade out a div on a click but also change some css values.
the issue im having is that the values change while the fade out is happening (too early). I need the values to change once the fade out has finished:
<script type="text/javascript">
$('#r_text').click(function() {
$(".box1_d").fadeOut();
$(".box1_c").css("top","0px");
});
</script>
Now when i run that, everything works but just not exactly how i'd like it.. I need the css values to be changed once the fadeout has finished, not while it's still happening.
is this possible?
if so, any ideas how?
thank you.
Use a callback function to modify the .css() as the second parameter to fadeOut(). It will fire when the fade completes.
<script type="text/javascript">
var fadeTime = 500;
$('#r_text').click(function() {
$(".box1_d").fadeOut(fadeTime, function() {
$(".box1_c").css("top","0px");
});
});
</script>
Provided you use jQuery version >= 1.5, you can/should utilize the Deferred object instead of using the callback parameter:
$('#r_text').click((function () {
var animations = {
initial: function () {
return $(".box1_d").fadeOut(1500);
},
following: function () {
return $(".box1_c").css("top","0px").animate({fontSize: '150%'});
},
onDone: function () {
alert('DONE!');
}
};
return function(e) {
$.when(animations.initial())
.pipe(animations.following)
.done(animations.onDone);
e.preventDefault();
};
}()));

The problem is that when i use the toggle function without any options i.e default options the 'is(':visible')' on the item returns me the correct state.
However when i use toggle("slow"), it reveals incorrect state and always shows the item operated upon by the toggle as visible false. Of course i am checking that inside the callback function so as to be sure that the animation is complete.
please look at the below code
jQuery(document).ready(function () {
var h3 = jQuery("#myAccordion").find('h3');
jQuery("#myAccordion").find('h3').find('span').addClass("ui-state-active ui-icon");
jQuery.each(h3, function () {
jQuery(this).bind('click', function () {
jQuery(this).next('div').toggle("slow", "swing", callback);
});
});
});
function callback () {
if (jQuery(this).next('div').is(':visible')) {
alert('visible--' + jQuery(this).next('div').is(':visible'));
jQuery(this).find('span').removeClass("ui-state-default ui-icon").addClass("ui-state-active ui-icon");
}
else {
alert('visible--' + jQuery(this).next('div').is(':visible')); // always goes into this 'else' even though the item is visible.
jQuery(this).find('span').removeClass("ui-state-active ui-icon").addClass("ui-state-default ui-icon");
}
}
However the same works perfectly fine when not using the "slow" option with toggle.
Update 2:
Check this out here http://jsfiddle.net/tariquasar/7xt7D/2/
Any pointers...
Update 1: This is the fiddle http://jsfiddle.net/tariquasar/7xt7D/
The context this is not extended to the callback function too. You could try doing this. I have updated the jsfiddle (click here). Ill paste the same here.
jQuery(document).ready(function () {
var h3 = jQuery("#myAccordion").find('h3');
jQuery("#myAccordion").find('h3').find('span').addClass("ui-state-active ui-icon"); // first the item is visible
jQuery.each(h3, function () {
jQuery(this).bind('click', function () {
console.log(this);
jQuery(this).next('div').toggle("slow","swing",callback(this));
});
});
});
function callback (that) {
setTimeout( function () {
console.log(jQuery(that).next('div').is(':visible'));
if (jQuery(that).next('div').is(':visible')) {
alert('visible--' + jQuery(that).next('div').is(':visible'));
jQuery(that).find('span').removeClass("ui-state-default ui-icon").addClass("ui-state-active ui-icon");
}
else {
alert('visible--' + jQuery(that).next('div').is(':visible'));
jQuery(that).find('span').removeClass("ui-state-active ui-icon").addClass("ui-state-default ui-icon");
}
}, 1000);
}
I have added a SetTimeout to get the result you wanted. The callback function is called after the animation completes. Yes. But not after the CSS changes to display:none. CSS change happens a few millisecs later.
However the same works perfectly fine when not using the "slow" option with toggle.
I'm not really sure about how you got it working with options other than slow
I have the following methods in javascript:
Controller.prototype.changeScene = function (curScene, newScene) {
sf.scene.hide(curScene);
sf.scene.show(newScene, curScene);
sf.scene.focus(newScene);
};
And in another JS Class:
Test.prototype.handleHide = function () {
alert("SceneDialog.handleHide()");
$(".screenOverlay").fadeOut("slow");
$(".dialogBox").fadeOut("slow");
};
sf.scene.hide() calls the handleHide method. In handleHide there's some animation, but it's not shown. The Controller doesn't wait for it to be finished.
I tried $.when(sf.scene.hide()).done() without any luck.
Any suggestions?
You can use the jQuery queue to keep a list of animations that are queued to occur only after the previous one has completed.
sf.scene.hide(curScene);
sf.scene.show(newScene, curScene);
sf.scene.focus(newScene);
would become:
sf.scene.hide(curScene);
sf.scene.queue(function() {
$(this).show(newScene, curScene);
$(this).dequeue();
});
sf.scene.queue(function() {
sf.scene.focus(newScene);
$(this).dequeue();
});
You can use the promise() function of jquery to call a callback when ALL animations are over.
Try out:
Test.prototype.handleHide = function (callback) {
$(".screenOverlay,.dialogBox").each(
function(i) {
$( this ).fadeOut("slow");
}
);
$(".screenOverlay,.dialogBox").promise().done(callback);
};
And pass the callback as an argument to handleHide. Your changeScene function should look like this:
Controller.prototype.changeScene = function (curScene, newScene) {
sf.scene.hide(curScene, function() {
sf.scene.show(newScene, curScene);
sf.scene.focus(newScene);
});
};
if you are using jquery animation functions, jquery generally provides a complete parameter which will be called when the function is complete.
using fadeout:
$('#test').fadeOut('slow', function() {
// fadeout is finished!! do something
});
I'm having a few issues getting a simple JQuery function to work that fades an element out, replaces the image within and fades back in again.
My function looks like this:
function nextPage() {
$("#leftPage").fadeOut("slow", function() {
$("#leftPage").html="<img src='page4.jpg'>";
$("#leftPage").fadeIn("slow");
});
$("#rightPage").fadeOut("slow", function() {
$("#rightPage").html="<img src='page5.jpg'>";
$("#rightPage").fadeIn("slow");
});
}
The fade in/out section works fine but the HTML is not being replaced with the new images. Can you see a problem with this?
function nextPage() {
$("#leftPage").fadeOut("slow", function () {
$("#leftPage").html("<img src='page4.jpg'>");
$("#leftPage").fadeIn("slow");
});
$("#rightPage").fadeOut("slow", function () {
$("#rightPage").html("<img src='page5.jpg'>");
$("#rightPage").fadeIn("slow");
});
}
You're assigning a string to .html which is actually a function that takes a string as an argument, instead of being a property you can assign things to.
Notice I've changed .html = "" to .html("") in the above snippet. This now passes a string to .html(), which updates the element accordingly.
The correct syntax for .html() is:
$("#leftPage").html("<img src='page4.jpg'>");
Try this:
function nextPage() {
$("#leftPage").fadeOut("slow", function() {
$("#leftPage").html("<img src='page4.jpg'>");
$("#leftPage").fadeIn("slow");
});
$("#rightPage").fadeOut("slow", function() {
$("#rightPage").html("<img src='page5.jpg'>");
$("#rightPage").fadeIn("slow");
});
}
jquery's html is a function, not a property. You pass in the html you want to replace the elements contents with as a parameter
Try:
$("#leftPage").html("<img src='page4.jpg'>");
and:
$("#rightPage").html("<img src='page5.jpg'>");
You're using jQuery's .html() wrong
function nextPage() {
$("#leftPage").fadeOut("slow", function() {
$("#leftPage").html("<img src='page4.jpg'>");
$("#leftPage").fadeIn("slow");
});
$("#rightPage").fadeOut("slow", function() {
$("#rightPage").html("<img src='page5.jpg'>");
$("#rightPage").fadeIn("slow");
});
}
I have this code that changes the image when a user rolls over a map area on my United States map. It is working perfectly. But I want the the images to have a smooth appearance and then a gradual fade away. What do I need to add to this code? Thanks!
$(document).ready(function() {
//set off state
var nav_off = "/images/state-map.png";
// functions for over and off
function over(image) {
$("#main-nav").attr("src", image);
}
function off() {
$("#main-nav").attr("src", nav_off);
}
$("#imagemap area").hover(
function () {
var button = $(this).attr("id");
over("/images/state-" + button + ".png");
},
function () {
off();
});
});
Try using jQuery's fadeOut/fadeIn effect.
Perhaps something like this:
function over(image) {
$("#main-nav").fadeOut(function () {
$(this).attr("src", image).fadeIn();
});
}
function off() {
$("#main-nav").fadeOut(function () {
$(this).attr("src", nav_off).fadeIn();
});
}
CSS transitions are an alternative way of handling this. There's a good tutorial (and demo) here.

Hello Guys!
I have been trying to create a simple sample code for my newest jQuery Plugin, but it doesn't seems to be working at all! Can anyone tell where I'm going wrong?, or can anyone provide me a new function to do it. So my problem is that when I mouse over an element classed trigger an another element classed eg should fadeIn(); but if the user takes out the mouse before the element classed eg fades in it should not be fading in anymore, but this is not working at all. I don't not what is getting wrong? Please help me out. (Below is my Problem HTML nad Jquery Code!)
HTML CODE
<div class="trigger">MouseOverMe</div>
<div class="eg">See Me!</div>
JQUERY CODE
function timereset(a)
{
var elem = $('.'+a);
if(elem.data('delay')) { clearTimeout(elem.data('delay')); }
}
$(document).ready(function () {
$('div.eg').hide();
$('div.trigger').mouseover(function () {
$('div.eg').delay(1000).fadeIn();
});
$('div.trigger').mouseout(function () {
timereset('eg');
$('div.eg').fadeOut();
});
});
THANKS IN ADVANCE
You don't need that timereset stuff, simply call stop() on the object and the previous effect will stop:
http://api.jquery.com/stop/
Update based on the new comment:
$('div.trigger').mouseout(function () {
$('div.eg').stop().hide();
});
jQuery
$('.trigger').hover(function() {
$('.eg').delay(1000).fadeIn();
}, function() {
$('.eg').stop(true, true).hide();
});
Fiddle: http://jsfiddle.net/UJBjg/1
Another option would be to clear the queued functions like:
$('div.trigger').mouseout(function () {
$('div.eg').queue('fx', []);
$('div.eg').fadeOut();
});
Bear in mind if the fadeOut/In has already started by using stop you could end up with a semi-transparent element.
EDIT
Here's an example: http://jsfiddle.net/Qchqc/
var timer = -1;
$(document).ready(function () {
$('div.eg').hide();
$('div.trigger').mouseover(function () {
timer = window.setTimeout("$('div.eg').fadeIn(function() { timer = -1; });",1000);
});
$('div.trigger').mouseout(function () {
if(timer != -1)
window.clearTimeout(timer);
$('div.eg').fadeOut();
});
});
