I am trying to incorporate infinite scroll with my current web site that is using a type of jQuery Masonry. I am trying to understand the language and the basic function of javascript (and html in general), but it can be quite overwhelming. I am also seeing different methods to add infinite scroll to a web page, including the use of php. Basically, I have no sense of direction as to which is the best method for my web site. Any tips or help is greatly appreciated. And I apologize for my lack of knowledge regarding this topic, but I just feel this is quite over my head... #_#
Here is my web site. It is my personal artwork collections:
http://themptyrm.com
add this in your html file
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script src="../jquery.masonry.min.js"></script>
<script src="../js/jquery.infinitescroll.min.js"></script>
and add this, here you can specify infinite scroll options
<script type="text/javascript">
var $container = $('#container');
$container.infinitescroll({
navSelector : '#page-nav', // selector for the paged navigation
nextSelector : '#page-nav a', // selector for the NEXT link (to page 2)
itemSelector : '.box', // selector for all items you'll retrieve
loading: {
finishedMsg: 'No more pages to load.',
img: 'http://i.imgur.com/6RMhx.gif'
}
},
// trigger Masonry as a callback
function( newElements ) {
var $newElems = $( newElements );
$container.masonry( 'appended', $newElems );
}
);
</script>
by the way your page looks great
if you have more doubts go here Masonry with Infinite scroll
Infinite Scroll, I've tried once in my project so here are some of the references I had used so far..
https://github.com/paulirish/infinite-scroll
http://www.jquery4u.com/tutorials/jquery-infinite-scrolling-demos/
jScroll is a jQuery plugin for infinite scrolling, written by Philip Klauzinski. Infinite scrolling; also known as lazy loading, endless scrolling, autopager, endless pages, etc.; is the ability to load content via AJAX within the current page or content area as you scroll down. The new content can be loaded automatically each time you scroll to the end of the existing content, or it can be triggered to load by clicking a navigation link at the end of the existing content.

I've been searching for an hour on how to nagivate within my Laravel website without refreshing the website (page layout), but I couldn't find a proper solution: one that not just loads the HTML, but actually replaces the content view within the layout.
This is my current dashboard:
So when clicking on a menu item within the blue area, I want the red content area to change without page refresh. What would be a scalable solution for this? I'm trying to follow the DRY (Don't repeat yourself) principle as much as possible.
Oh, please don't mark this topic as a clone of other topics as I've seen most of them but without proper solution. Hope anyone can help me out.
Changing a view without page load means we need to use the ajax techology. Vuejs is a frontend frameework the allows us to acomplish that easily with its axios library
I believe you can get this done by using jQuery load function -
$(function () {
$("#menu_option_a").on("click", function () {
$("#dashboard").load("View1.html");
});
$("#menu_option_b").on("click", function () {
$("#dashboard").load("View2.html");
});
});
I am using UberGallery for my site:
http://www.ubergallery.net/
Here is a sample of the page with Uber Gallery called directly in the HTML
http://www.goloyal.com/clients/dealers-mlm.php
If you click on a thumbnail it opens the popup div.
Some pages have a lot of thumbs, so they load slowly, so I tried to call the Uber Gallery through an Ajax so the page would load, then the thumbs could take their time:
/old-dealers-mlm.php
The loader works exactly as I hoped, however when you click on the thumbnails it opens in a new page (not the pop up div)
I am calling THIS div in my ajax
/div-dealers-mlm.php
Which also has the popups showing correctly.
I do understand that the pages are loaded separately, and I know it requires a special conversation to tell one page to do something in the other. However, I am not sure what I need to relay to the parent/original page, or how to do it to start testing. Any ideas?
THANKS!
The problem is that you're setting up the colorbox on links that don't exist yet. You need to replace your current colorbox code with this:
$(document).ready(function(){
$(document).on("click", "a[rel='colorbox']", function(e){
e.preventDefault();
var url = this.href;
$.colorbox({href: url, maxWidth: "99%", maxHeight: "99%", opacity: ".5"});
});
});
This uses jQuery .on() to bind the click event to all current and future a elements with a rel attribute that equals colorbox.
So I've decided to use the jQuery Mobile framework to build my new mobile website. It has this feature of loading any local href link by ajax, which is great. But the new page that loads doesn't respond to any of the javascript. I've got a home page and page 2, both of which have the same html layout which a few changes in the content, I'll give an example.
I have made a navigation menu that slides in from the left and pushes the main content to the right. When I click on a page link, it loads the new page through ajax, but then on the new page, if I click the menu button, jQuery doesn't pick this up and so nothing happens (the menu doesnt slide out).
$(document).ready(function() {
$( ".menu-trigger" ).click(function() {
console.log("1")
if ($( 'nav' ).hasClass('navTransform')) {
console.log("2")
$( 'nav' ).removeClass('navTransform');
$( 'article' ).removeClass('articleTransform');
}
else {
console.log("3")
$( 'nav' ).addClass('navTransform');
$( 'article' ).addClass('articleTransform');
}
});
});
This jQuery script is in a seperate .js file thats included in the header of both the pages. I know the script works normally because when i refresh the page, the menu trigger works. Is there a known work around for this?
The workaround for this is to use appropriate jQM handler pageinit() instead of jQuery ready handler.
pageinit = DOM ready
One of the first things people learn in jQuery is to use the
$(document).ready() function for executing DOM-specific code as soon
as the DOM is ready (which often occurs long before the onload event).
However, in jQuery Mobile site and apps, pages are requested and
injected into the same DOM as the user navigates, so the DOM ready
event is not as useful, as it only executes for the first page. To
execute code whenever a new page is loaded and created in jQuery
Mobile, you can bind to the pageinit event.
So, your code might look like this:
$(document).on("pageinit", "#page1", function(){
//Your init code for page 1 goes here
});
$(document).on("pageinit", "#page2", function(){
//Your init code for page 2 goes here
});
Firstly I am very new to all forms of javascript, particularly anything remotely AJAX. That said, over the course of the last day I have managed to code a script that dynamically refreshes a single div and replaces it with the contents of a div on another page.
The problem however is that several of my other scripts do not work in the ajax refreshed content. The most important of which being "colorbox".
I have spent several hours this evening researching this and am seeing lot's of stuff regarding .load, .live... updating the DOM on refresh etc...etc... But to be quite honest most of it is going over my head currently and I wouldn't know where to begin in terms of integrating it with the code I currently have.
My Ajax refresh code is as follows (My apologies if I haven't used best practice, it was my first attempt):-
$(function() {
$(".artist li.artist").removeClass("artist").addClass("current_page_item");
$("#rightcolumnwrapper").append("<img src='http://www.mywebsite.com/wp-content/images/ajax-loader.gif' id='ajax-loader' style='position:absolute;top:400px;left:190px;right:0px;margin-left:auto;margin-right:auto;width:100px;' />");
var $rightcolumn = $("#rightcolumn"),
siteURL = "http://" + top.location.host.toString(),
hash = window.location.hash,
$ajaxSpinner = $("#ajax-loader"),
$el, $allLinks = $("a");
$ajaxSpinner.hide();
$('a:urlInternal').live('click', function(e) {
$el = $(this);
if ((!$el.hasClass("comment-reply-link")) && ($el.attr("id") != 'cancel-comment-reply-link')) {
var path = $(this).attr('href').replace(siteURL, '');
$.address.value(path);
$(".current_page_item").removeClass("current_page_item");
$allLinks.removeClass("current_link");
$el.addClass("current_link").parent().addClass("current_page_item");
return false;
}
e.preventDefault();
});
$.address.change(function(event) {
$ajaxSpinner.fadeIn();
$rightcolumn.animate({ opacity: "0.1" })
.load(siteURL + event.value + ' #rightcolumn', function() {
$ajaxSpinner.fadeOut();
$rightcolumn.animate({ opacity: "1" });
});
});});
I was hoping someone might be kind enough to show me the sort of modifications I would need to make to the above code in order to have the colorbox load when the contents of #rightcolumn have been refreshed.
There is also a second part to this question. My links to the pictures themselves are now also being effected by the hashtag due to the above code which will in turn prevent the images themselves from loading correctly in the colorbox I should imagine. How can I prevent these images from being effected and just have them keep the standard URL. I only want the above code to effect my internal navigation links if at all possible.
Many thanks guys. I look forward to your replies.
That's a lot of code to review so I'll focus first on the conceptual side of things. Maybe that you will give you some clues...
It sounds like when you load content via Ajax the DOM is changed. No worries, that's kind of what we expect. However, scripts loaded before the Ajax calls may have difficulty if they are bound to elements that weren't there at page load time or are no longer there.
JQuery's live function is one solution to that. Instead of binding to a specific element (or collection of elements) at particular point in time, live lets you specify a binding to an element (or collection) of elements without regard to when they show up in the DOM (if ever).
ColorBox, however, in its default "vanilla" use abstracts that all away and, I believe, uses classic DOM binding - meaning the elements must be present at bind time. (Since you don't show your call to ColorBox I can't see how your using it.)
You may want to consider re-initalizing ColorBox after each content load by Ajax to be certain the binding happens the way you need it to.
Use $('selector').delegate() it watches the DOM of 'selector' and .live() is deprecated.
Use this to watch your elements AND fire the colorbox initilization. This way the colorbox is not dependent on the DOM element, but the other way around.
$("body").delegate("a[rel='lightbox']", "click", function (event) {
event.preventDefault();
$.colorbox({href: $(this).attr("href"),
transition: "fade",
innerHeight: '515px',
innerWidth: '579px',
overlayClose: true,
iframe: true,
opacity: 0.3});});
This should basically solve your problem and is cross browser tested.
The a[rel='lightbox'] in the delegate closure is the reference to what ever link you're clicking to fire the colorbox, whether it has been loaded with the initial DOM or with an AJAX request and has been added to the DOM in a live fashion. ie: any tag like this:
<a rel='lightbox' href="http://some.website.com">Launch Colorbox</a>
I have a task to change envelope icons on the main Activities view page (Work Place, My Work -> Activities) for every row in the grid, depending on the custom status of the row in crm 4.0. I need to do it using JavaScript. Does anybody know if there is a way to do that and where should the JavaScript code be placed? I am assuming that I need to intercept grid onLoad event, go through the grid, check the condition and flip the url of the icon. But I cannot figure out how to hook into that event...
Thanks very much!
I got several very useful advices and here is what I got so far.
1. I added SiteMap to load a custom page, instead of default one (/workplace/home_activities.aspx)
2. Here is the code of the custom page, placing onreadystatechange in the html was the only way I could get this function to run. Do not know why.
HTML>
HEAD>
TITLE>
script language="javascript" type="text/javascript">
function Run()
{
var objIframe = getIframe();
if(objIframe.readyState == "complete")
{
var docFrame = objIframe.contentWindow.document;
var grid = docFrame.getElementById("crmGrid");
var allRecords = grid.InnerGrid.AllRecords;
for(var i=0; i
function getIframe()
{
return document.getElementById("wraperActivitiesFrame");
}
/script>
/HEAD>
body >
iframe id="wraperActivitiesFrame" src="/workplace/home_activities.aspx" WIDTH="100%" HEIGHT="100%" onreadystatechange="Run()">
/HTML>
The issue I am having now is that the function does not run again when I try to page the grid. I have 2 pages of Activities; when the page loads for the first time - I have my alert boxes, but when I click on "page 2" arrow - nothing happens. Why??? What I am doing wrong?
You kinda can hook into that event. You create a "wrapper" HTML page that you load in CRM instead of the default activities grid via Sitemap. This wrapper contains a full-size IFrame in which you load the actual grid, and in the IFrame's onreadystatechange handler (for readyState == 4), you traverse the grid's DOM (jQuery might make this a little easier, but I haven't used jQuery much myself) and do whatever changes you need to do (that means the JavaScript goes within the wrapper HTML page). If you call this via setInterval and put a try-catch around it, this will even be safe against grid refreshes and browsing through the pages.
