jQuery, Shadowbox and AJAX - javascript

I would like to load some content using AJAX and Shadowbox
Basically I would like the user to goto a page in case javascript is off. So this is what I want to do :-
1) Cancel the click event i.e the User must not go to a different page.
2) Load content using ajax function in jQuery
3) Show the content inside a shadow box
My code works ok until loading content using ajax but the shadowbox is not displayed and the URL is gettin refreshed i guess, everything goes blank.
jQuery(document).ready(function($){
// rounded corners
$('img').addClass('corner iradius16');
DD_roundies.addRule('#nav li a',4,true);
DD_roundies.addRule('.grid',6,true);
$('h2 a').bind('click', function() {
var id = $(this).attr('id');
$.ajax({
url: "/ajax-post.php?p="+id,
success: function(data){
Shadowbox.open({
content: data,
player: "html",
height: 350,
width: 350
});
}
});
return false;
});
UPDATE 1
tried this code, and as soon as the shadowbox loads, the document gets reloaded and white.
Shadowbox.init({
skipSetup: true,
players: ["html"]
});
// LOAD
jQuery(document).ready(function($){
// rounded corners
$('img').addClass('corner iradius16');
DD_roundies.addRule('#nav li a',4,true);
DD_roundies.addRule('.grid',6,true);
$('.post h2 a').bind('click', function() {
var id = $(this).attr('id');
$.ajax({
url: "<?php bloginfo( 'template_directory'); ?>/ajax-post.php?p="+id,
success: function(data){
show_box(data);
}
});
return false;
});
});
//shadowbox
function show_box(html) {
Shadowbox.open({
content: html,
player: "html",
height: 350,
width: 350
});
}
UPDATE 2
Okay got the prbolem, the html that I am getting via ajax has some javascript in it and that is the reason for the page reload.
Why is this happening ? Any ideas ?

Since you're not getting any JavaScript errors try debugging by breaking it down:
Ensure that the binding to and overriding of the click event is functioning properly:
$('h2 a').bind('click', function() {
alert('click even fired');
return false;
});
If that works, check the data that your ajax request is returning:
$('h2 a').bind('click', function() {
var id = $(this).attr('id');
$.ajax({
url: "ajax-post.php?p="+id,
success: function(data){
alert(data);
}
});
return false;
});
The code looks like it should work, so I'm guessing there's either something wrong elsewhere (in which case the first test will likely fail) or you're getting some really odd data returned.

Need to run
Shadowbox.setup('h2 a');
This will reinitialise and bind it to any ajax loaded content

Split divs with class from html to be used by script

I am trying to build my own 'infinite scroll' so I have more control than using a plugin.
I currently have the below:
$(window).scroll(function(){
if ($(window).scrollTop() == $(document).height() - $(window).height()){
loadNew();
}
});
function loadNew(){
var next = $('a.next').attr('href');
$.ajax({
url: next,
success: function(html){
** GET ALL '.grid-item' TO USE BELOW**
var $newElems = $( **ALL .grid-item** ).css({ opacity: 0 });
$newElems.imagesLoaded(function(){
$newElems.animate({ opacity: 1 });
$container.masonry( 'appended', $newElems, true );
});
}
});
return false;
}
This is so far triggering when the user scrolls to the bottom of the page, its then getting the 'next' URL from the pagination and returning the full HTML of the page in the success call.
As you can see in my code, I want to get all divs with the class '.grid-item' to be used by the code below.
I am really struggling to get the '.grid-item' divs seperated to be used.
Is anyone able to explain how I can do this?
What you can do is convert the returned html to a jQuery object so that you can parse it using find() to get the relevant elements. This is done easily by wrapping the html like this, $(html), but if there is a doctype declaration then that will break it. What I normally do is make sure I've only got data that starts from the opening html tag.
Try this...
function loadNew(){
var next = $('a.next').attr('href');
$.ajax({
url: next,
success: function(html){
html = html.substr("<html"); // remove the doctype
var $newElems = $(html).find(".grid-item").css({ opacity: 0 });
$newElems.imagesLoaded(function(){
$container.append($newElems).masonry("appended", $newElems, true);
$newElems.css({ opacity: 1 });
});
}
});
return false;
}
Also, you need to first append the elements to the container, and then tell masonry that you've done so. The masonry appended call doesn't actually append anything.

jQuery .on click event doesn't always fire on Ajax loaded content

I have a page where I dynamically load contents. Inside the $(document).ready I have similar event handlers:
$(document).on("click", ".content_button", function(e){
e.preventDefault();
e.stopPropagation();
// content
});
The problem is that the mouse click only recognised at around 90% of the clicks. It seems totally random. At other times I have to push the same button 4-5 times, and then it works. I have no error in the console, even the CSS part works every time:
div.content_button:active {
top: 2px;
}
I can't seem to find a solution. I use jQuery 1.11, it works like this on Win10, Win7, inside Firefox, and even on iPad or Android.
Do you have any ideas about what can be the problem?
Edit:
data.control contains the .content_button divs (buttons) in HTML.
And here is the part, which loads the buttons:
$.ajax({
url: 'worker.php',
async: false,
cache: false,
type: "POST",
data: { action:"update" },
dataType: "json",
success:function(data) {
if(data.actionresult == 1)
{
$('div#container').hide("slide", { direction: "down" }, 500);
$('div#container').promise().done(function() {
$('div#container').html(data.control);
$('div#container').show();
});
}
else
{
// handle error
}
}
});
$(document).ready(function(){
$(".content_button").on("click", function(e){
e.preventDefault();
e.stopPropagation();
// content
});
});
It must be done like this.
Have you tried with
$(function() {
var count = 0;
$('body').on('click', '.content_button', function() {
count++;
$('#count').html(count);
});
});
https://jsfiddle.net/byexstpq/
Ok, I have found the problem, it is this:
div.content_button:active {
top: 2px;
}
On mouseDown it moves 2 pixels, so it is possible that the link won't be there after a mouseUp - so technically the click event won't fire as the mouseUp happens over another element.
I hope this will help others.

Masonry items not reloaded when cliking ajax load more button

Hi everyone i have one problem about masonry items.
I have created this DEMO from codepen.io
In this demo you can see there is this javascript code:
$(window).load(function()
{
$( function() {
var $container = $('.posts-holder');
$container.masonry({
isFitWidth: true,
itemSelector: '.kesif-gonderi-alani'
});
});
});
I show only 10 posts when a page is opened. If user want to show other 10 posts then user needs to click (show more button). I created this ajax function for show more posts.
$('.showmore').live("click",function(event)
{
event.preventDefault();
var ID = $(this).attr("id");
var P_ID = $(this).attr("rel");
var URL=$.base_url+'diger_fotograflar_ajax.php';
var dataString = "lastid="+ ID+"&profile_id="+P_ID;
if(ID)
{
$.ajax({
type: "POST",
url: URL,
data: dataString,
cache: false,
beforeSend: function(){ $("#more"+ID).html('<img src="wall_icons/ajaxloader.gif" />'); },
success: function(html){
$("div.posts-holder").append(html).each(function(){
$('.posts-holder').masonry('reloadItems');
});
$("#more"+ID).remove();
}
});
}
else
{
$("#more").html('The End');// no results
}
return false;
});
this code working when clicking showmore button $('.posts-holder').masonry('reloadItems'); but collecting new posts in one place. But when I change the width of the page everything is improving.
I think that you can use $container.masonry(); after adding your elements, like this :
$("div.posts-holder").append(html).each(function(){
$('.posts-holder').masonry('reloadItems');
});
$container.masonry();
You can see it working here.
Hope that can help.
you have to use the appended method of masonry ... otherwise how would it know that you have added any new element.
Adding the elements simply wont align them as masonry doesnt have any event listner for new element added.
var el = $('<div class="kesif-gonderi-alani" style="height:300px;"></div>')
$container.masonry().append( el ).masonry( 'appended',el );
Hers is small demo on codepen http://codepen.io/knaman2609/pen/xbJMRY

jQuery script delayed by AJAX request - how to fix it?

I'm making a simple responsive Wordpress Theme and I want only one page there, and the content loaded via AJAX, so I have an AJAX function:
jQuery(document).ready(function(){
jQuery.ajaxSetup({cache:false});
jQuery("#mainnav a").click(function(){
var post_link = jQuery(this).attr("href");
jQuery("body").load(post_link);
return false;
});
});
It's meant to load entire pages content (entire body) on clicking menu links. And it works well.
But the problem is I have a jQuery script responsible for centering content div:
(function (jQuery) {
jQuery.fn.centerAlign = function() {
return this.each(function(i){
var w = jQuery(this).width();
var ow = jQuery(this).outerWidth();
var ml = (w + (ow - w)) / 2;
var h = jQuery(this).height();
var oh = jQuery(this).outerHeight();
var mt = (h + (oh - h)) / 2;
jQuery(this).css("margin-top", "-" + mt + "px");
jQuery(this).css("top", "50%");
jQuery(this).css("margin-left", "-" + ml + "px");
jQuery(this).css("left", "50%");
jQuery(this).css("position", "absolute");
});
};
})(jQuery);
jQuery(document).ready(function() {
jQuery("#content").centerAlign();
});
That script centers the #content div at reload instatly, so I mean there is no delay. The div is centered from the start.
Problem is when I combine that scripts, because after AJAX loads the entire body, #content div is not positioned for ~1 second (in top-left corner of the page) and then it comes back to its place. So jQuery script works with a delay.
I coulnd't find a solution for that problem, .on and .live don't work for me. I think I could just load each page content into a #content div, not entire "body", but I don't know how to make it.
I'd appreciate if you can help me with that, so it will just resize the #content div with animation, not position it from start.
EDIT:
Ok, I ended up with such code:
jQuery(function(){
jQuery("#mainnav a").click(function(e){
var content=jQuery("#content");
jQuery.ajax({
url: jQuery(this).attr('href'),
dataType: "HTML",
beforeSend: function(){
content.empty();
},
success: function(){
content.load();
},
error : function(){
content.html("<p>Przepraszamy, ale strona jest chwilowo niedostępna</p>");
},
});
e.preventDefault();
})
})
It should work, but the problem is that I can't figure out what should I put in that lines:
success: function(){
content.load();
It workd up to that point. I clears the #content div but when I put content.load("#content"); it loads entire page, with menu and footer. And I want to load just #content content.
EDIT:
Ok. Firebug shows that this code is working, but there is nothing shown within the #content div in broswer window.
jQuery(function(){
jQuery("#mainnav a").click(function(e){
var content=jQuery("#content");
var href=jQuery(this).attr('href');
var text = jQuery(this).find('#content').html();
jQuery.ajax({
url: jQuery(this).attr('href'),
dataType: "HTML",
beforeSend: function(){
content.empty();
},
success: function(){
content
.html(text)
.centerAlign();
},
error : function(){
content.html("<p>Content Unavailable</p>");
},
});
e.preventDefault();
})
})
I think you're on the right track with your new code, you just need to fill out your success function:
success: function( html ){
html = jQuery(html).find('#content').html();
content.html(html).centerAlign();
},
or perhaps (using th1rdey3's idea):
success: function( html ){
html = jQuery(html).find('#content').centerAlign().html();
content.html( html );
},
You could centerAlign #content before placing it inside body. Something like this
var $div = jQuery('<div/>').load(post_link);
$div.find('#content').first().centerAlign();
jQuery('body').html($div.html());
or only loading the content part
var $div = jQuery('<div/>').load(post_link);
jQuery('#content').first().html($div.find('#content').first().html());

live() alternative on() not working jQuery 1.9

I have code do ajax method for loading new content
But I have problem with the new content, the links not applying the action i did like
preventDefault and the ajax method, just after loading the new content
clicking on links make the page reload like there was no ajax code at all
In JQ 1.8 working grate with live() method, but after updating jQuery, not working as it should with on() method
The old code working right and have no problem with it
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.1/jquery.min.js"></script>
<script>
function loadContent(url){
$.ajax({
url: url,
dataType: 'html',
cache: false
}).done(function(html){
var $html = $(html);
$('title').html($html.filter('title').text());
$('#main').replaceWith($html.find('#main'));
$('.nav-menu').replaceWith($html.find('.nav-menu'));
$('.nav-below').replaceWith($html.find('.nav-below'));
});
}
$(function(){
// Get The Content Action
$('.nav-menu li a,#nav-below a,#main a').live('click',function(e) {
href = $(this).attr("href");
loadContent(href);
history.pushState('', 'New URL: '+href, href);
e.preventDefault();
// go top after showing the content
$('html, body').animate({scrollTop:0}, 'slow');
});
// THIS EVENT MAKES SURE THAT THE BACK/FORWARD BUTTONS WORK AS WELL
window.onpopstate = function(event){
loadContent(location.pathname);
$('html, body').animate({scrollTop:0}, 'slow');
};
});
</script>
The new updated code
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>
function loadContent(url){
$.ajax({
url: url,
dataType: 'html',
cache: false
}).done(function(html){
var $html = $(html);
$('title').html($html.filter('title').text());
$('#main').replaceWith($html.find('#main'));
$('.nav-menu').replaceWith($html.find('.nav-menu'));
$('.nav-below').replaceWith($html.find('.nav-below'));
});
}
$(function(){
// Get The Content Action, ‡‡=‡=‡=‡=L0000K HERE=‡=‡=‡=‡‡ Not workin JQ 1.9
$('.nav-menu li a,#nav-below a,#main a').on('click',function(e) {
href = $(this).attr("href");
loadContent(href);
history.pushState('', 'New URL: '+href, href);
e.preventDefault();
// go top after showing the content
$('html, body').animate({scrollTop:0}, 'slow');
});
// THIS EVENT MAKES SURE THAT THE BACK/FORWARD BUTTONS WORK AS WELL
window.onpopstate = function(event){
loadContent(location.pathname);
$('html, body').animate({scrollTop:0}, 'slow');
};
});
</script>
The problem right here
$('.nav-menu li a,#nav-below a,#main a').on('click',function(e) {
Thank you :)
You don't simply s/live/on, you need to read the documentation of on() to see the changes required to update your code (on is similar to the old delegate()).
If you want to make it work exactly like live(), try...
$(document).on('click', '.nav-menu li a,#nav-below a,#main a', function(e) { });
However, if you can, you're better off choosing the most common persistent ancestor. This means that the events won't have to go all the way up to document to be handled. For example, body probably covers 99.9% of situations. However, it's probably more like #some-container.
for easy usage you can use something like this:
$.fn.follow = function (event, callback) {
$(document).on(event, $(this).selector, callback);
}
and you can use it like:
$("#myselector").follow("click",function(){
/*some callback code*/
});
you can still use event data in your plugin
$("#expform").follow("submit",function(e){
e.preventDefault();
});
