Jquery show info in popup after jquery post method if link is yet hovered

I made popup with actor info if user hover on link whith actor name. But if user hovering links very fast its often can be 2 popup in same time. Is it possible to check if link is yet hovered so popup will show certain info on certain link?
Here is my code
$('.persons a').mouseenter(function(){
var url = $(this).attr('href');
var elem = $(this);
$('#person_info').remove();
$.post(
'/site/get_person_info',
'url=' + url,
function(data) {
if (data != 'error') {
function show_creator_info(url) {
if ($('.persons a:hover').length != 0) {
$(elem).append(data);
}
}
show_creator_info(url);
}
}
);
$('.persons a').mouseleave(function(){
$('#person_info').remove();
});
});
and here is a demo enter link description here
div "В ролях"

Set a variable called loading to know if you're fetching data or not and do not request again if loading is true.
var loading = false;
$('.persons a').mouseenter(function(){
if (loading) return;
var url = $(this).attr('href');
var elem = $(this);
$('#person_info').remove();
loading = true;
$.post(
'/site/get_person_info',
'url=' + url,
function(data) {
if (data != 'error') {
function show_creator_info(url) {
if ($('.persons a:hover').length != 0) {
$(elem).append(data);
}
}
show_creator_info(url);
}
loading = false;
}
);
$('.persons a').mouseleave(function(){
$('#person_info').remove();
});
});

Keep browser history with django-el-pagination (lazy pagination)

Im using django-el-pagination to do lazy loading of entries.
When I click on an entry and then use the browser back button, all of the lazy loading is gone, I tried to add window.history.pushState() but then I only get the current page i.e.?page=4 when I use the browser back button, and all of the entries on top is not loaded.
Is there any way to implement a correct history so that the user is back at the same place when they use the browser back button?
$.endlessPaginate({
paginateOnScroll: true,
paginateOnScrollMargin: 400,
paginateOnScrollChunkSize: 2,
onCompleted: function(context, fragment) {
window.history.pushState(null, null, context.url);
}
});
Edit 1
Here is the JavaScript for the .endlessPaginate function:
'use strict';

// Fix JS String.trim() function is unavailable in IE<9 #45
if (typeof(String.prototype.trim) === "undefined") {
String.prototype.trim = function() {

};
}
$.fn.endlessPaginate = function(options) {
var defaults = {
// Twitter-style pagination container selector.

// Set this to true to use the paginate-on-scroll feature.

// If paginate-on-scroll is on, this margin will be used.
paginateOnScrollMargin : 1,
// If paginate-on-scroll is on, it is possible to define chunks.
paginateOnScrollChunkSize: 0
},
settings = $.extend(defaults, options);
var getContext = function(link) {
return {
key: link.attr('rel').split(' ')[0],

};
};
return this.each(function() {
var element = $(this),
loadedPages = 1;
// Twitter-style pagination.
element.on('click', settings.moreSelector, function() {
var link = $(this),
html_link = link.get(0),
container = link.closest(settings.containerSelector),
loading = container.find(settings.loadingSelector);
// Avoid multiple Ajax calls.
if (loading.is(':visible')) {
return false;
}
link.hide();
loading.show();
var context = getContext(link);
// Fire onClick callback.
if (settings.onClick.apply(html_link, [context]) !== false) {
var data = 'querystring_key=' + context.key;
// Send the Ajax request.
$.get(context.url, data, function(fragment) {
container.before(fragment);
container.remove();
// Increase the number of loaded pages.
loadedPages += 1;
// Fire onCompleted callback.
settings.onCompleted.apply(
html_link, [context, fragment.trim()]);
});
}
return false;
});
// On scroll pagination.
if (settings.paginateOnScroll) {
var win = $(window),
doc = $(document);
doc.scroll(function(){
if (doc.height() - win.height() -
win.scrollTop() <= settings.paginateOnScrollMargin) {
// Do not paginate on scroll if chunks are used and
// the current chunk is complete.
var chunckSize = settings.paginateOnScrollChunkSize;
if (!chunckSize || loadedPages % chunckSize) {
element.find(settings.moreSelector).click();
} else {
element.find(settings.moreSelector).addClass('endless_chunk_complete');
}
}
});
}
// Digg-style pagination.
element.on('click', settings.pagesSelector, function() {
var link = $(this),
html_link = link.get(0),
context = getContext(link);
// Fire onClick callback.
if (settings.onClick.apply(html_link, [context]) !== false) {
var page_template = link.closest(settings.pageSelector),
data = 'querystring_key=' + context.key;
// Send the Ajax request.
page_template.load(context.url, data, function(fragment) {
// Fire onCompleted callback.
settings.onCompleted.apply(
html_link, [context, fragment.trim()]);
});
}
return false;
});
});
};
$.endlessPaginate = function(options) {
return $('body').endlessPaginate(options);
};
})(jQuery);

short answer: no. The whole point of 'endless pagination' is to not reload a (new) page, therefore there is no history.

My javascript function only fires once

I have a pretty basic step by step wizard I created. When you select an option from a drop down menu on page 1, I load a new page via jQuery ajax. If you hit back, it loads the original page again.
However after loading the original page again, my modelSelect() function that loads page 2 stops working. Doesn't fire at all. I'm not exactly sure what I'm doing wrong.
I'm hoping someone can see what I'm doing wrong. My code is below:
//Collapse panel handling
var group = jQuery('.estimator-container');
jQuery('.tab-click').click(function() {
group.find('.collapse.in').collapse('hide');
jQuery(this).parent().toggleClass('active');
});
/* -------------------------------------- *\
New form handler
\* -------------------------------------- */
function modelSelect(v) {
jQuery('#page_2, .estimator-container').toggle();
// Ajax for loading page_2
jQuery.ajax({
type: "POST",
data: v,
success: function() {
jQuery('.estimator-app').load(templateUrl + "/page-estimator2.php?p=" + v);
}
});
}
jQuery('.estimator-panel').on('change', '.select-model', function() {
var v = jQuery(this).val();
modelSelect(v);
}); //end on change function
// Back and continue handling
jQuery('.estimator-app').on('click', '.estimator_form_btn_next', function() {
var backBtn = jQuery('.estimator_form_btn_back');
var continueBtn = jQuery('.estimator_form_btn_next');
var firstPage = jQuery('#contact-first-page');
var lastPage = jQuery('#contact-last-page');
if (firstPage.is(":visible")) {
firstPage.toggle();
lastPage.toggle();
}
}); //end continue
// Go back
jQuery('.estimator-app').on('click', '.estimator_form_btn_back', function() {
var backBtn = jQuery('.estimator_form_btn_back');
var continueBtn = jQuery('.estimator_form_btn_next');
var firstPage = jQuery('#contact-first-page');
var lastPage = jQuery('#contact-last-page');
if (lastPage.is(":visible")) {
firstPage.toggle();
lastPage.toggle();
} else {
jQuery.ajax({
type: "POST",
// data: v,
success: function() {
jQuery('.estimator-app').load(templateUrl + "/estimator-initial.php");
}
});
}
}); //end continue

Simple delegation.
Adding jQuery(document).on('change', '.select-model', function(){ on line 29 made it work.

Change your this line:
jQuery('.estimator-panel').on('change', '.select-model', function() {
to this
jQuery(document).off('change', '.select-model').on('change', '.select-model', function(e){
e.preventDefault();
because if HTML is loaded after page load OR by some kind of JS, you need to deattach event and then attach back,

Change div content and hash url

I made a fully functional Ajax Content Replacement script. The problem is that it adds forwards like /#about or /#work or /#contact to the adress but when I reload the site, the main page will be show. Why? How is it possible that when i type in the adress the right subpage will be show?
Someone told me that the problem is that I added the file manually when I use popstate. So I want a solution without popstate. I am not a Javascript expert but I would like to learn it. Because popstate but this is very circuitous.
window.location.hash = $(this).attr('href');
My .html files are in stored in /data/. The strange thing is that it finds the file but when I try to find it manually,the page show the main page or when I refresh the site with F5 the main page will be show,too.
Can you help me and show me how it works. We can use my code to find the error. Thanks a lot.
Here is the Websitelink : Demo Link
function refreshContent() {
var targetPage = 'home';
var hashMatch = /^#(.+)/.exec(location.hash);
// if a target page is provided in the location hash
if (hashMatch) {
targetPage = hashMatch[1];
}
$('#allcontent').load('data/' + targetPage + '.html');
}
$(document).ready(function(){
refreshContent();
window.addEventListener('hashchange', refreshContent, false);
$('.hovers').click(function() {
var page = $(this).attr('href');
$('#allcontent').fadeOut('slow', function() {
$(this).animate({ scrollTop: 0 }, 0);
$(this).hide().load('data/' + page +'.html').fadeIn('normal');
});
});
});
$('.hovers').click(function() {
window.location.hash = $(this).attr('href');
$.get('data/'+this.href, function(data) {
$('#allcontent').slideTo(data)
})
return false
})

You should load the initial page based on location.hash (if provided) on page load:
function refreshContent() {
var targetPage = 'home';
var hashMatch = /^#!\/(.+)/.exec(location.hash);
// if a target page is provided in the location hash
if (hashMatch) {
targetPage = hashMatch[1];
}
$('#allcontent').load('data/' + targetPage + '.html');
}
$(document).ready(function(){
refreshContent();
...
You can make back and forward work by listening to the Window.onhashchange event:
window.addEventListener('hashchange', refreshContent, false);
Do note that this doesn't work in Internet Explore 7 or lower.
Edit:
Okay, try this:
var $contentLinks = null;
var contentLoaded = false;
function refreshContent() {
var targetPage = 'home';
var hashMatch = /^#(.+)/.exec(location.hash);
var $content = $('#allcontent');
// if a target page is provided in the location hash
if (hashMatch) {
targetPage = hashMatch[1];
}
// remove currently active links
$contentLinks.find('.active').removeClass('active');
// find new active link
var $activeLink = $contentLinks.siblings('[href="' + targetPage + '"]').find('.navpoint');
// add active class to active link
$activeLink.addClass('active');
// update document title based on the text of the new active link
window.document.title = $activeLink.length ? $activeLink.text() + ' | Celebrate You' : 'Celebrate You';
// only perform animations are the content has loaded
if (contentLoaded) {
$content
.fadeOut('slow')
.animate({ scrollTop: 0 }, 0)
;
}
// after the content animations are done, load the content
$content.queue(function() {
$content.load('data/' + targetPage + '.html', function() {
$content.dequeue();
});
});
if (contentLoaded) {
$content.fadeIn();
}
contentLoaded = true;
}
$(document).ready(function() {
$contentLinks = $('.hovers');
refreshContent();
window.addEventListener('hashchange', refreshContent, false);
$contentLinks.click(function(e) {
e.preventDefault();
window.location.hash = '!/' + $(this).attr('href');
});
});

setInterval with other jQuery events - Too many recursions

I'm trying to build a Javascript listener for a small page that uses AJAX to load content based on the anchor in the URL. Looking online, I found and modified a script that uses setInterval() to do this and so far it works fine. However, I have other jQuery elements in the $(document).ready() for special effects for the menus and content. If I use setInterval() no other jQuery effects work. I finagled a way to get it work by including the jQuery effects in the loop for setInterval() like so:
$(document).ready(function() {
var pageScripts = function() {
pageEffects();
pageURL();
}
window.setInterval(pageScripts, 500);
});
var currentAnchor = null;
function pageEffects() {
// Popup Menus
$(".bannerMenu").hover(function() {
$(this).find("ul.bannerSubmenu").slideDown(300).show;
}, function() {
$(this).find("ul.bannerSubmenu").slideUp(400);
});
$(".panel").hover(function() {
$(this).find(".panelContent").fadeIn(200);
}, function() {
$(this).find(".panelContent").fadeOut(300);
});
// REL Links Control
$("a[rel='_blank']").click(function() {
this.target = "_blank";
});
$("a[rel='share']").click(function(event) {
var share_url = $(this).attr("href");
window.open(share_url, "Share", "width=768, height=450");
event.preventDefault();
});
}
function pageURL() {
if (currentAnchor != document.location.hash) {
currentAnchor = document.location.hash;
if (!currentAnchor) {
query = "section=home";
} else {
var splits = currentAnchor.substring(1).split("&");
var section = splits[0];
delete splits[0];
var params = splits.join("&");
var query = "section=" + section + params;
}
$.get("loader.php", query, function(data) {
$("#load").fadeIn("fast");
$("#content").fadeOut(100).html(data).fadeIn(500);
$("#load").fadeOut("fast");
});
}
}
This works fine for a while but after a few minutes of the page being loaded, it drags to a near stop in IE and Firefox. I checked the FF Error Console and it comes back with an error "Too many Recursions." Chrome seems to not care and the page continues to run more or less normally despite the amount of time it's been open.
It would seem to me that the pageEffects() call is causing the issue with the recursion, however, any attempts to move it out of the loop breaks them and they cease to work as soon as setInterval makes it first loop.
Any help on this would be greatly appreciated!

I am guessing that the pageEffects need added to the pageURL content.
At the very least this should be more efficient and prevent duplicate handlers
$(document).ready(function() {
pageEffects($('body'));
(function(){
pageURL();
window.setTimeout(arguments.callee, 500);
})();
});
var currentAnchor = null;
function pageEffects(parent) {
// Popup Menus
parent.find(".bannerMenu").each(function() {
$(this).unbind('mouseenter mouseleave');
var proxy = {
subMenu: $(this).find("ul.bannerSubmenu"),
handlerIn: function() {
this.subMenu.slideDown(300).show();
},
handlerOut: function() {
this.subMenu.slideUp(400).hide();
}
};
$(this).hover(proxy.handlerIn, proxy.handlerOut);
});
parent.find(".panel").each(function() {
$(this).unbind('mouseenter mouseleave');
var proxy = {
content: panel.find(".panelContent"),
handlerIn: function() {
this.content.fadeIn(200).show();
},
handlerOut: function() {
this.content.slideUp(400).hide();
}
};
$(this).hover(proxy.handlerIn, proxy.handlerOut);
});
// REL Links Control
parent.find("a[rel='_blank']").each(function() {
$(this).target = "_blank";
});
parent.find("a[rel='share']").click(function(event) {
var share_url = $(this).attr("href");
window.open(share_url, "Share", "width=768, height=450");
event.preventDefault();
});
}
function pageURL() {
if (currentAnchor != document.location.hash) {
currentAnchor = document.location.hash;
if (!currentAnchor) {
query = "section=home";
} else {
var splits = currentAnchor.substring(1).split("&");
var section = splits[0];
delete splits[0];
var params = splits.join("&");
var query = "section=" + section + params;
}
var content = $("#content");
$.get("loader.php", query, function(data) {
$("#load").fadeIn("fast");
content.fadeOut(100).html(data).fadeIn(500);
$("#load").fadeOut("fast");
});
pageEffects(content);
}
}

Thanks for the suggestions. I tried a few of them and they still did not lead to the desirable effects. After some cautious testing, I found out what was happening. With jQuery (and presumably Javascript as a whole), whenever an AJAX callback is made, the elements brought in through the callback are not binded to what was originally binded in the document, they must be rebinded. You can either do this by recalling all the jQuery events on a successful callback or by using the .live() event in jQuery's library. I opted for .live() and it works like a charm now and no more recursive errors :D.
$(document).ready(function() {
// Popup Menus
$(".bannerMenu").live("hover", function(event) {
if (event.type == "mouseover") {
$(this).find("ul.bannerSubmenu").slideDown(300);
} else {
$(this).find("ul.bannerSubmenu").slideUp(400);
}
});
// Rollover Content
$(".panel").live("hover", function(event) {
if (event.type == "mouseover") {
$(this).find(".panelContent").fadeIn(200);
} else {
$(this).find(".panelContent").fadeOut(300);
}
});
// HREF Events
$("a[rel='_blank']").live("click", function(event) {
var target = $(this).attr("href");
window.open(target, "_blank");
event.preventDefault();
});
$("a[rel='share']").live("click", function(event) {
var share_url = $(this).attr("href");
window.open(share_url, "Share", "width=768, height=450");
event.preventDefault();
});
setInterval("checkAnchor()", 500);
});
var currentAnchor = null;
function checkAnchor() {
if (currentAnchor != document.location.hash) {
currentAnchor = document.location.hash;
if (!currentAnchor) {
query = "section=home";
} else {
var splits = currentAnchor.substring(1).split("&");
var section = splits[0];
delete splits[0];
var params = splits.join("&");
var query = "section=" + section + params;
}
$.get("loader.php", query, function(data) {
$("#load").fadeIn(200);
$("#content").fadeOut(200).html(data).fadeIn(200);
$("#load").fadeOut(200);
});
}
}
Anywho, the page works as intended even in IE (which I rarely check for compatibility). Hopefully, some other newb will learn from my mistakes :p.
