EDIT: This software package is the full and undoctored version of what I'm trying to fix here. The problem is in the /data/renderpage.js script. Feel free to examine this before continuing.

I really appreciate all the help guys!

I am polishing a jQuery script to do the following in a rigid sequence...
Fade out the text.
Shrink the size of the container div.
Preload the remote HTML ///without showing it yet!///
Open the size of the container div.
Fade in the new remote HTML.
I do not mind if steps 1 and 2, 4 and 5 are combined to be one whole step (fade/resize at the same time). It's when the new HTML is loaded it interrupts the entire animation, even from the beginning.
The idea is that I do not want my remote HTML to show until after the animation renders right. I want the original text to fade out and the container div close up, then, behind the scenes, ready the text of the new HTML, and then have the container div open up and fade the new text in.
It seems when I call the load(url) function, it instantaneously loads the page up, and the animations are still running (like the new HTML ends up fading out, only to fade back in, and not the original text out and then the new one in). Either that, or the whole function is calling each line at the same time, and it's disrupting the page-changing effect I want.
Here's my current script setup...
$(document).ready(function() {
// Start-Up Page Load (Cover, ToC, etc.)
$('#content').load('pages/page1.htm');
// Navigating Pages
$(document).on('click', 'a', function(e) {
e.preventDefault();
var ahref = $(this).attr('href');
$('#content_container').animate({height: 'hide'}, 500);
$('#content').fadeTo('slow', 0.25);
$('#content').load(ahref);
$('#content').css({opacity: 0.0});
$('#content').fadeTo('slow', 1.0);
$('#content_container').animate({height: 'show'}, 500);
return false;
});
});
What is it wrong I'm doing here? I have used the delay() function on every one of those steps and it doesn't solve the problem of holding back the new text.
jQuery objects can provide a promise for their animation queues by calling .promise on the jQuery element.
You can wait on one or more of these to complete using $.when() and then perform other operations.
The following does a fade out and slide up in parallel with the load, then (only when the animations complete), slides it down then fades it in (in sequence):
$(document).on('click', 'a', function (e) {
e.preventDefault();
var ahref = $(this).attr('href')
var $container = $('#content_container');
var $content = $('#content');
// Slide up and fadeout at the same time
$container.animate({
height: 'hide'
}, 500);
$content.fadeOut();
// Load the content while fading out
$('#content').load(ahref, function () {
// Wait for the fade and slide to complete
$.when($container.promise(), $content.promise()).then(function () {
// Slide down and fadein (in sequence)
$container.animate({
height: 'show'
}, 500, function () {
$content.fadeTo('slow', 1.0);
});
});
});
});
JSFiddle: http://jsfiddle.net/TrueBlueAussie/pffm1tnb/3/
The only issue with this version is that the load may complete faster than the fadeout/slideup and show the new data too early. In this case you want to not use load, but use get (so you have control over when to insert the new content):
// Load the content while fading out
$.get(ahref, function (data) {
// Wait for the fade and slide to complete
$.when($container.promise(), $content.promise()).then(function () {
$content.html(data);
// Slide down and fadein (in sequence)
$container.animate({
height: 'show'
}, 500, function () {
$content.fadeTo('slow', 1.0);
});
});
});
JSFiddle: http://jsfiddle.net/TrueBlueAussie/pffm1tnb/4/
Notes:
return false from a click handler does the same as e.stopPropagation() and e.preventDefault(), so you usually only need one or the other.
I started with the JSFiddle from #Pete as no other sample was handy. Thanks Pete.
Update:
Based on the full code now posted, you are returning full pages (including header and body tags). If you change your code to .load(ahref + " #content" ) it will extract only the part you want. This conflicts with the second (better) example I provided which would need the pages returned to be partial pages (or extract the required part only).
Additional Update:
As $.get also returns a jQuery promise, you can simplify it further to:
$.when($.get(ahref), $container.promise(), $content.promise()).then(function (data) {
$content.html(data);
// Slide down and fadein (in sequence)
$container.animate({
height: 'show'
}, 500, function () {
$content.fadeTo('slow', 1.0);
});
});
The resolve values from each promise passed to $.when are passed to the then in order, so the first parameter passed will be the data from the $.get promise.
JSFiddle: http://jsfiddle.net/TrueBlueAussie/pffm1tnb/11/
The issue is because you're not waiting for the hide animations to finish before loading the content, or waiting for the content to load before starting the show animations. You need to use the callback parameters of the relevant methods. Try this:
$(document).on('click', 'a', function(e) {
e.preventDefault();
var ahref = $(this).attr('href'),
$content = $('#content'),
$contentContainer = $('#content_container');
$contentContainer.animate({ height: 'hide'}, 500);
$content.fadeTo('slow', 0.25, function() {
// animation completed, load content:
$content.load(ahref, function() {
// load completed, show content:
$content.css({ opacity: 0.0 }).fadeTo('slow', 1.0);
$contentContainer.animate({ height: 'show' }, 500);
});
});
});
Note that for the effect to work the most effectively on the UI you would need to perform the load() after the animation which takes the longest to complete has finished.
Instead of using the load() function, you can use the get() function and its callback paramater to save the HTML into a variable before actually putting it into the element with html().
After doing all the animations to fade out and close the old box (and maybe inside an animation-finished callback function) you'll want to use something like the following:
$.get(ahref, function(data) {
// JQuery animation before we want to see the text.
$('#content').html(data); // actually inserts HTML into element.
// JQuery animation to fade the text in.
});
Using a bunch of the code everyone posted here, I rewrote the segment I originally had to follow suit. This is now my working result.
$(document).ready(function() {
// Start-Up Page Load (Cover, ToC, etc.)
$('#content').load('pages/page1.htm');
// Navigating Pages
$(document).on('click', 'a', function(e) {
e.preventDefault();
var ahref = $(this).attr('href');
$('#content').fadeTo('slow', 0.0)
$('#content_container').animate({height: 'hide'}, 500, function(){
$('#content').load(ahref + '#content', function(){
$('#content_container').animate({height: 'show'}, 500, function(){
$('#content').fadeTo('slow', 1.0);
});
});
});
return false;
});
});
You can use deferred or callbacks function
$(document).on('click', 'a', function(e) {
e.preventDefault();
var ahref = $(this).attr('href');
var dfd1 = $.Deferred();
var dfd2 = $.Deferred();
var dfd3 = $.Deferred();
var dfd4 = $.Deferred();
$('#content_container').animate({height: 'hide'}, 500, function(){
dfd1.resolve();
});
dfd1.done(function() {
$('#content').fadeTo('slow', 0.25, function() {
dfd2.resolve();
});
});
dfd2.done(function() {
$('#content').load(ahref, function() {
$('#content').css({opacity: 0.0});
dfd3.resolve();
});
});
dfd3.done(function() {
$('#content').fadeTo('slow', 1.0, function() {
dfd4.resolve();
});
});
dfd4.done(function() {
$('#content_container').animate({height: 'show'}, 500);
});
return false;
});
In my code I have external script that adds some element to my page. This script loads async after document.ready:
<script src="http://any.com/script.js"></script>
This script contains next:
$.ajax({
url: '/anyScript',
complete: function(){
alert('yo'); // FIRED
$('body').append('<div id="xxx" />'); // FIRED
}
});
I need to wait until this element will appear and add some styles to it
$(function(){
$('body').on('load','#xxx', function(){
$(this).css({
background:'red',
width: 100,
height: $('#first_el').height()
});
});
});
This doesn't fire. What to do?
UPDATED: http://jsfiddle.net/81ucdoLo/1/
This solution is based on the assumption that you don't have any control over the external script. So the proposed solution is to use an interval based solution to check whether the target element is loaded if so style it and then stop the interval.
In that case, try use $.getScript() to load the script like
jQuery.getScript('http://any.com/script.js', function () {
var interval = setInterval(function () {
var $el = $('#xxx');
if ($el.length) {
clearInterval(interval);
$el.css({
background: 'red',
width: 100,
height: $('#first_el').height()
});
}
}, 500);
})
Demo: Fiddle
You can try using ajaxComplete as shown :
$( document ).ajaxComplete(function() {
$('#xxx').css({
background:'red',
width: 100,
height: $('#first_el').height()
});
});
Working Demo
This should wait for the element to be ready:
$(function(){
$("#xxx").css('top','123px');
//OR
$("#xxx").addClass('topMargin');
});
Do somthing like this, call your js function using window.onload, it will execute doSomthing function after your page load.
window.onload = function() {doSomthing();}
function doSomthing()
{
$("#xxx").css('top','123px');
}
Or add timeout,
setTimeout(doSomthing,1000);
this will delay the call process, and will call after specified time.
What if you try this :

I used a flowplayer tutorial to make some ajax tabbed content but the it doesn't use any kind of a loading indication in between content load. How can I add that to this script? http://pastebin.com/PebcJspn
<script>
$(function() {
$(".feed-tabs ul").tabs("div.feeds > div", {
effect: 'fade',
onBeforeClick: function(event, i) {
// get the pane to be opened
var pane = this.getPanes().eq(i);
// only load once. remove the if ( ... ){ } clause if you want the page to be loaded every time
if (pane.is(":empty")) {
// load it with a page specified in the tab's href attribute
pane.load(this.getTabs().eq(i).attr("href"));
}
}
});
});
</script>
You can try add an element with a loading gif before call the method .load() and it will be removed when .load() inserts the html result.
<script>
$(function() {
$(".feed-tabs ul").tabs("div.feeds > div", {
effect: 'fade',
onBeforeClick: function(event, i) {
// get the pane to be opened
var pane = this.getPanes().eq(i);
// only load once. remove the if ( ... ){ } clause if you want the page to be loaded every time
if (pane.is(":empty")) {
//add this
pane.append("<img src='http://mentalized.net/activity-indicators/indicators/ilcu/roller.gif'/>")
// load it with a page specified in the tab's href attribute
pane.load(this.getTabs().eq(i).attr("href"));
}
}
});
});
</script>
I have a link that uses the Twitter Bootstrap Popover version 1.3.0 to show some information. This information includes a link, but every-time I move my mouse from the link to the popover, the popover just disappears.
How can I hold popover open long enough to enable the mouse to move into it? Then when the mouse moves out of the link and popover, hide it?
Or is there some other plugin that can do this?
With bootstrap (tested with version 2) I figured out the following code:
$("a[rel=popover]")
.popover({
offset: 10,
trigger: 'manual',
animate: false,
html: true,
placement: 'left',
template: '<div class="popover" onmouseover="$(this).mouseleave(function() {$(this).hide(); });"><div class="arrow"></div><div class="popover-inner"><h3 class="popover-title"></h3><div class="popover-content"><p></p></div></div></div>'
}).click(function(e) {
e.preventDefault() ;
}).mouseenter(function(e) {
$(this).popover('show');
});
The main point is to override template with mouseleave() enabler. I hope this helps.
Bootstrap 3 and above
Simple, just use the container option and have it as the element that is calling the popover. This way, the popover is a child of the element that calls it. Hence, you are technically still hovering over the parent, because the child popover belongs to it.
For example:
HTML:
<div class="pop" data-content="Testing 12345">This has a popover</div>
<div class="pop" data-content="Testing 12345">This has a popover</div>
<div class="pop" data-content="Testing 12345">This has a popover</div>
jQuery:
Running an $.each() loop over every one of my elements that I want a popover binded to its parent. In this case, each element has the class of pop.
$('.pop').each(function () {
var $elem = $(this);
$elem.popover({
placement: 'top',
trigger: 'hover',
html: true,
container: $elem
});
});
CSS:
This part is optional, but recommended. It moves the popover down by 7 pixels for easier access.
.pop .popover {
margin-top:7px;
}
WORKING DEMO
Just to add to Marchello's example, if you want the popover to disappear if the user moves their mouse away from the popover and source link, try this out.
var timeoutObj;
$('.nav_item a').popover({
offset: 10,
trigger: 'manual',
html: true,
placement: 'right',
template: '<div class="popover" onmouseover="clearTimeout(timeoutObj);$(this).mouseleave(function() {$(this).hide();});"><div class="arrow"></div><div class="popover-inner"><h3 class="popover-title"></h3><div class="popover-content"><p></p></div></div></div>'
}).mouseenter(function(e) {
$(this).popover('show');
}).mouseleave(function(e) {
var ref = $(this);
timeoutObj = setTimeout(function(){
ref.popover('hide');
}, 50);
});
This is a little hacky, but building off of marchello's example, I did this (no need for template):
$(".trigger-link").popover({
trigger: "manual",
}).on("click", function(e) {
e.preventDefault();
}).on("mouseenter", function() {
var _this = this;
$(this).popover("show");
$(this).siblings(".popover").on("mouseleave", function() {
$(_this).popover('hide');
});
}).on("mouseleave", function() {
var _this = this;
setTimeout(function() {
if (!$(".popover:hover").length) {
$(_this).popover("hide")
}
}, 100);
});
The setTimeout helps ensure that there's time to travel from the trigger link to the popover.
This issue on the bootstrap github repo deals with this problem. fat pointed out the experimental "in top/bottom/left/right" placement. It works, pretty well, but you have to make sure the popover trigger is not positioned statically with css. Otherwise the popover won't appear where you want it to.
HTML:
<span class="myClass" data-content="lorem ipsum content" data-original-title="pop-title">Hover me to show a popover.</span>
CSS:
/*CSS */
.myClass{ position: relative;}
JS:
$(function(){
$('.myClass').popover({placement: 'in top'});
});
Solution worked for us for Bootstrap 3.
var timeoutObj;
$('.list-group a').popover({
offset: 10,
trigger: 'manual',
html: true,
placement: 'right',
template: '<div class="popover" onmouseover="$(this).mouseleave(function() {$(this).hide();});"><div class="arrow"></div><div class="popover-inner"><h3 class="popover-title"></h3><div class="popover-content"><p></p></div></div></div>'
}).mouseenter(function(e) {
$(this).popover('show');
}).mouseleave(function(e) {
var _this = this;
setTimeout(function() {
if (!$(".popover:hover").length) {
$(_this).popover("hide");
}
}, 100);
});
Here's my take: http://jsfiddle.net/WojtekKruszewski/Zf3m7/22/
Sometimes while moving mouse from popover trigger to actual popover content diagonally, you hover over elements below. I wanted to handle such situations – as long as you reach popover content before the timeout fires, you're save (the popover won't disappear). It requires delay option.
This hack basically overrides Popover leave function, but calls the original (which starts timer to hide the popover). Then it attaches a one-off listener to mouseenter popover content element's.
If mouse enters the popover, the timer is cleared. Then it turns it listens to mouseleave on popover and if it's triggered, it calls the original leave function so that it could start hide timer.
var originalLeave = $.fn.popover.Constructor.prototype.leave;
$.fn.popover.Constructor.prototype.leave = function(obj){
var self = obj instanceof this.constructor ?
obj : $(obj.currentTarget)[this.type](this.getDelegateOptions()).data('bs.' + this.type)
var container, timeout;
originalLeave.call(this, obj);
if(obj.currentTarget) {
container = $(obj.currentTarget).siblings('.popover')
timeout = self.timeout;
container.one('mouseenter', function(){
//We entered the actual popover – call off the dogs
clearTimeout(timeout);
//Let's monitor popover content instead
container.one('mouseleave', function(){
$.fn.popover.Constructor.prototype.leave.call(self, self);
});
})
}
};
Finally I fix this problem. Popover disappear is because Popover not child node of link, it is child node of body.
So fix it is easy, change bootstrap-twipsy.js content:
change .prependTo(document.body) to .prependTo(this.$element)
and fix position problem cause by change.
and some use link tiger popover will cause popover with link too, so add a span contain link, so problem solved.
This is a version of Wojtek Kruszewski solution. This version handle popover blink when mouse go back to trigger. http://jsfiddle.net/danielgatis/QtcpD/
(function($) {
var originalLeave = $.fn.popover.Constructor.prototype.leave;
$.fn.popover.Constructor.prototype.leave = function(obj) {
var self = (obj instanceof this.constructor ? obj : $(obj.currentTarget)[this.type](this.getDelegateOptions()).data("bs." + this.type));
originalLeave.call(this, obj);
if (obj.currentTarget) {
var current = $(obj.currentTarget);
var container = current.siblings(".popover");
container.on("mouseenter", function() {
clearTimeout(self.timeout);
});
container.on("mouseleave", function() {
originalLeave.call(self, self);
});
}
};
var originalEnter = $.fn.popover.Constructor.prototype.enter;
$.fn.popover.Constructor.prototype.enter = function(obj) {
var self = (obj instanceof this.constructor ? obj : $(obj.currentTarget)[this.type](this.getDelegateOptions()).data("bs." + this.type));
clearTimeout(self.timeout);
if (!$(obj.currentTarget).siblings(".popover:visible").length) {
originalEnter.call(this, obj);
}
};
})(jQuery);
I tried the solutions from #Wotjek Kruszewski and #danielgatis, but neither worked for me. Caveat: I'm using Bootstrap v2.1.0, not v3. This solution is in coffeescript (why are people still using plain javascript? =)).
(($) ->
originalLeave = $.fn.popover.Constructor::leave
$.fn.popover.Constructor::leave = (e) ->
self = $(e.currentTarget)[#type](#_options).data(#type)
originalLeave.call #, e
if e.currentTarget
container = $(".popover")
container.one "mouseenter", ->
clearTimeout self.timeout
container.one "mouseleave", ->
originalLeave.call self, e
) jQuery
Here is what i did:
e = $("a[rel=popover]")
e.popover({
content: d,
html:true,
trigger:'hover',
delay: {hide: 500},
placement: 'bottom',
container: e,
})
This is a very simple and awesone solution to this probelm, which i found out by looking into the bootstrap tooltip code. In Bootstrap v3.0.3 here is the line of code i noticed:
this.options.container ? $tip.appendTo(this.options.container) : $tip.insertAfter(this.$element)
this says that if container property of popover is defined then the popover gets appendTo() the element instead of insertAfter() the original element, all you need to do is just pass the element as container property. Because of appendTo() the popover becomes part of the link on which the hover event was binded and thus keeps the popover open when mouse moves on it.
This works for me on BootStrap 3:
el.popover({
delay: {hide: 100}
}).on("shown.bs.popover", function(){
el.data("bs.popover").tip().off("mouseleave").on("mouseleave", function(){
setTimeout(function(){
el.popover("hide");
}, 100);
});
}).on("hide.bs.popover", function(ev){
if(el.data("bs.popover").tip().is(":hover"))
ev.preventDefault();
});
At the end of the conversation linked by #stevendaniels is a link to a Twitter Bootstrap extension called BootstrapX - clickover by Lee Carmichael. This changes the popover from an overlarge tooltip into an interactive control, which can be closed by clicking elsewhere on the form, a close button, or after a timeout. Its easy to use, and worked very well for the project I needed it in. Some examples of its usage can be found here.
I didn't like any of the answers I've found, so I combined some answers that were close to make the following code. It allows you to end up just typing $(selector).pinnablepopover(options); every time you want to make a 'pinnable' popover.
Code that makes things easy:
$.fn.popoverHoverShow = function ()
{
if(this.data('state') !== 'pinned')
{
if(!this.data('bs.popover').$tip || (this.data('bs.popover').$tip && this.data('bs.popover').$tip.is(':hidden')))
{
this.popover('show');
}
}
};
$.fn.popoverHoverHide = function ()
{
if (this.data('state') !== 'pinned')
{
var ref = this;
this.data('bs.popover').$tip.data('timeout', setTimeout(function(){ ref.popover('hide') }, 100))
.on('mouseenter', function(){ clearTimeout($(this).data('timeout')) })
.on('mouseleave', function(){ $(this).data('timeout', setTimeout(function(){ ref.popover('hide') }, 100)) });
this.on('mouseenter', function(){ clearTimeout($(this).data('timeout')) });
}
};
$.fn.popoverClickToggle = function ()
{
if (this.data('state') !== 'pinned')
{
this.data('state', 'pinned');
}
else
{
this.data('state', 'hover')
}
};
$.fn.pinnablepopover = function (options)
{
options.trigger = manual;
this.popover(options)
.on('mouseenter', function(){ $(this).popoverHoverShow() })
.on('mouseleave', function(){ $(this).popoverHoverHide() })
.on('click', function(){ $(this).popoverClickToggle() });
};
Example usage:
$('[data-toggle=popover]').pinnablepopover({html: true, container: 'body'});

I think my problem is very small, but i still need for help in my jquery code, I think it's all about js syntax:
$(function() {
// Options for SuperBGImage
$.fn.superbgimage.options = {
randomtransition: 2, // 0-none, 1-use random transition (0-7)
z_index: -1, // z-index for the container
slideshow: 1, // 0-none, 1-autostart slideshow
slide_interval: 2000, // interval for the slideshow
randomimage: 1, // 0-none, 1-random image
speed: 'slow' // animation speed
};
// initialize SuperBGImage
$('#thumbs').superbgimage().hide();
});
$(function() {
var $j = jQuery.noConflict();
$j(document).ready(function(){
$j('.menu-nav li').hover(
function() {
$j(this).addClass("active");
$j(this).find('.ulwrapper').stop(false, true).fadeIn();
$j(this).find('.ulwrapper .ulwrapper').stop(false, true).fadeOut('fast');
},
function() {
$j(this).removeClass("active");
$j(this).find('div').stop(false, true).fadeOut('fast');
}
);
$j('.ulwrapper').hover(
function() {
$j('.parent').addClass("active_tab");
},
function() {
$j('.parent').removeClass("active_tab");
}
);
});
});
the first code is for the Big image where the other is to work with my multi-level menu. I tried to workaround this by changing
$(function() {
to
$j(document).ready(function(){
but the browser only runs one code! and gives me:
Uncaught TypeError: Property '$' of object [object DOMWindow] is not a function
(anonymous function)
I am waiting your help, thanks too much.
Once you call jQuery.noConflict, the "$" binding won't work anymore. You don't say why you're calling it, but you can use just "jQuery" instead of "$". Your "$j" variable is local to that function where you call "noConflict".
Also, it doesn't make sense to do this:
$(function() {
$(function() {
// ...
});
});
which is what you're doing in that second "ready" handler. That is, you're setting up a "ready" handler from inside another one, which makes no sense really.
For using $j in your script,you should insert following code:
<script type="text/javascript">
$j=jQuery.noConflict();
</script>
Best Luck..
