I have the following odd problem:
My first page has the exactly same header and section as the second page - my second page has smooth scrolling, my first page had it but lost it somehow.
I weren't able to track down how the template creator made those smoothing effects - does anybody know how something like this gets implemented? And has somebody maybe a clou why the first page hasn't this effect while they have the same implementations?
Thanks in advance,
Trusto
Edit:
I tracked down the implementation:
(function ($) {
var o = $('html');
if (o.hasClass('desktop')) {
include('js/jquery.mousewheel.min.js');
include('js/jquery.simplr.smoothscroll.min.js');
$(document).ready(function () {
$.srSmoothscroll({
step: 150,
speed: 800
});
});
}
})(jQuery);
The page were it doesn't work is a php-file, the others are html.
I found the issue - I implemented the unedited jquery-file in the first page which override the scrolling function.
Thanks for your help.

My website is : https://365arts.me/
So it loads about 16mbs of pics(Yes I know, I'm stupid. I'll try to change it very soon, also if someone could tell me a way to reduce size of do something else(like dynamic loading only when needed, if something like that exists) I'd be very grateful).
I added a preloader for it using:
[html]:
<div class="spinner-wrapper">
<div class="spinner">
<div class="dot1"></div>
<div class="dot2"></div>
</div>
</div>
and corresponging [jquery]:
<script>
$(document).ready(function() {
//Preloader
$(window).on("load", function() {
preloaderFadeOutTime = 500;
function hidePreloader() {
var preloader = $('.spinner-wrapper');
preloader.fadeOut(preloaderFadeOutTime);
}
hidePreloader();
});
});</script>
this works well but the problem is I have a javascript code that comes and says Hi! but it runs only for 2.8 seconds. So if loading takes up more than that, It doesnt show up. Can someone please tell me how to make sure that it loads only exactly after loading is completed.
Thanks a ton.
Code for my website:
https://github.com/richidubey/365-Days-Of-Art/blob/master/index.html
this may work
document.addEventListener('DOMContentLoaded', function() {
// your code here
}, false);
if you are happy with pure javascript
My first suggestion is to just get rid of the "Hi!" message since you already have a splash page in the form of the loader. But if you really want that second splash page, you can use the JQuery when() method:
$(window).on("load", function() {
$.when($('.spinner-wrapper').fadeOut(500)).then(displaySplashPage);
});
This assumes that displaySplashPage() is your function for showing the "Hi!" message.
You don't need $(document).ready() and window.on("load") here. Document ready waits for the HTML to be built, then applies event listeners/functions/etc to the structure. Window onload waits for everything to get loaded, then fires. In your case, you're trying to wait for all your pictures to load, so you only need onload.
You might need to have a container around all your main content set to opacity: 0 that switches to opacity: 1 as part of displaySplashPage(). That would prevent things from leaking through as you do the .fadeOut() on the loader.
JavaScript version - run js code when everything is loaded + rendered
window.onload = function() {
alert("page is loaded and rendered");
};
jQuery version (if you need it instead pure JS)
$(window).on('load', function() {
alert("page is loaded and rendered");
});
You can try this:
<script>
// Preloader
$(window).on("load", function() {
fadeOutTime = 500;
sayHelloDuration = 5000;
function hideSayHello() {
var sayHello = $('.say-hello');
sayHello.fadeOut(fadeOutTime);
}
function hidePreloader() {
var preloader = $('.spinner-wrapper');
preloader.fadeOut(fadeOutTime);
setTimeout(function() {
hideSayHello();
}, sayHelloDuration);
}
hidePreloader();
});
</script>
Also, remove the code from lines 83 ~ 87:
<script>
$(document).ready(function() {
$('.say-hello').delay(2800).fadeOut('slow');
});
</script>
About your website performance, you can improve a lot of things right now:
Use smaller thumbnail images on your front page, don't load FULL SIZE images at once. "work-showcase" section is really heavy without real necessity.
Try to incorporate src-set and smaller images for small screens, larger/heavier images for bigger screens. All modern browsers support it, and it will improve performance/loading speed.
Try to lazyload your big images, e.g. only when users scroll down to them, not before. It may take some work to integrate it with your image viewer, but it will additionally speed things up on initial load. My favorite library for this is this one: https://github.com/aFarkas/lazysizes but, you may find something else...
Unrelated to your original question, I have noticed that you have a bug in your HTML - see this screenshot. What kind of code editor do you use? Instead of empty space it apparently inserts invisible dots symbols which are not good. Actually, it's not the invisible dot (that's my editor's space indentation symbol), it's caused by 2 long dash (instead of short dash or minus) in your code after opening html comment tag:
I have a lot of pictures on my page. and I want to do some javascript and PHP processing when the user scrolls down to each image. I have come up with the follwing:
$(window).scroll(function(){
hT = $('.Picture-1A:eq(3)').offset().top,
hH = $('.Picture-1A:eq(3)').outerHeight(),
wH = $(window).height(),
wS = $(this).scrollTop();
if ((wS >= (hT+hH-wH))){
alert('you have scrolled to the h1!');
}
});
The above example only works if I reach to a certain image. And I want to do something when the scroll reach an image. I want to get it's ID and process that in PHP using AJAX.
Let's assume that the following are the images:
<div class="Picture-1A"></div>
<div class="Picture-1A"></div>
<div class="Picture-1A"></div>
What I want to do is add 1 impression to the image that has appeared on the window. and I want to do that using AJAX every time the user scrolls down the page.
That's it
Update:
I have found a great library thanks to Eugenio Enko. and here is how it's done:
Include the library code in your project after jQuery:
If you want it to trigger for each image, then use each like so:
$('.Picture-1A').each(function() {
$(this).waypoint(function(direction){
alert($(this).html());
});
});
But I am having trouble getting the html of $(".Picture-1A").html() using this it returns undefiend
Here you can view an example using the old waypoint:
http://codepen.io/eugenioenko/pen/qZMqOW
$(document).ready(function(){
$('.spfx-scroll-p').waypoint(function(){
alert('scrolled');
},{offset:'90%'});
});
There are two libraries I know that could help you with that:
http://imakewebthings.com/waypoints/
http://scrollmagic.io/
The second one is more complete and has much more option, but for what you need, it seems that waypoint should work well enough.
best regards.
My javascript skills are pretty basic but I'm trying to learn more, so was wondering if someone could help me out or point me in the right direction as I'm a bit puzzled with a site I'm working on.
The site is: http://epaints.co.uk/ basically I am trying to get the home page slider to slide automatically on page load, at the moment it only slides when the user clicks the navigation buttons.
$('.caro-arrow.caro-arrow-r').click( function () {
setTimeout("$('.caro-arrow.caro-arrow-r').click()", 4000);
});
I always thought it was a simple as adding the below code for it to auto slide, but it doesn't seem to work:
auto: true,
autoControls: true
Like I said, if anyone can help me out or point me in the right direction, it would be greatly appreciated!
Thanks for your help :-)
Use the following code in your $(document).ready(function () { /* HERE */ })
$('.caro-arrow.caro-arrow-r').click( function () {
setTimeout("$('.caro-arrow.caro-arrow-r').click()", 4000);
}).trigger('click');
We don't need to write the same function twice, just trigger click so that it runs on page load.
I'm quite new at using jquery but learning a bit everyday. I have solved many problems searching this web but I can't seem to find any solution for this one:
The web I'm workign at the moment use quite a lot of page anchors.
I have localscroll and scrollto as jquery libraries.
I animated the transition with this little script:
<script type="text/javascript">
$(document).ready(function () {
$('.scrolllento').localScroll({ duration: 1000 });
});
</script>
and it works fine whatever I add the class "scrolllento" to the cointainer of my links.
Now the problem I have is when a link jumps to an anchor of inside different page. my client has asked me if it's possible to load the page first then move to the anchor with same web transition.
I have been working on it with my little knowdlege and this is what I have atm:
<script type="text/javascript">
$(document).ready(function () {
var nosalto = $(location).attr('href');
if (nosalto.indexOf("HistoriaBMG") > 0) {
$.fn.gotoAnchor = function (anchor) {
location.href = this.selector;
}
$('#historia').gotoAnchor();
}
});
</script>
"HistoriaBMG" is the new page and "#historia" is the anchor I want to go inside that page.
and it seems again that it works...
the problem is I have no idea how to implement now the transition as the class "scrolllento" in the container of the link going to ../HistoriaBMG is ignored.
could anyone help me? thanks so much in advance and excuse my english, hope this question is clear enough.
According to the localScroll docs:
The plugin also adds a function, $.localScroll.hash() , that checks the URL in the address bar, and if there's a hash(#an_id), it will scroll to the element. It accepts a hash of settings, just like $.localScroll. You will likely call it on document ready. Check the regular example to see it in action.
So you simply need to call $.localScroll.hash()on $(document).ready()
I'm making a simple little website to apply a different formatting style to Reddit posts, I'm trying to add the infinite-scroll jQuery plugin but it doesn't do anything. I tried following the (very simple) instructions on the infinite-scroll page and when it didn't do anything I thought I must have entered something wrongly, but then I just copy/pasted the code from the Masonry/Infinite-Scroll example and it still didn't work. Masonry is working perfectly (finally) but I just can't figure out what is wrong with infinite-scroll. I understand the basics of jQuery and JavaScript, but obviously not as much as most of you people, so could you please help me out and let me know what is wrong? My site is live at reddit.ymindustries.com.
Thanks heaps, you guys have rarely failed me so far.

EDIT: If there aren't enough images to fill up the page on the homepage, visit reddit.ymindustries.com/r/aww for more images.
EDIT 2: I believe I located the issue, it is described here: https://github.com/paulirish/infinite-scroll/issues/5
Now to figure out a fix...
EDIT 3: Added a little bit of a hack in to make it sort of work, but it just seems to loop the second page endlessly now. Hmm...
I think your problem is actually css. Make your page longer that client area height. add more images to $container
Point is, botom edge of your $container need to pass bottom of window so scroll event fires so infinite scroll can react on this event and calculate weather or not edge is reached
BTW, in same cases, for instance, when I shrink my window, the example you set is working.
=== UPDATE ===
I found some time to play with infinitescroll and here is final working script, just set pathParse method in your script
$(function () {
var $container = $('#itemContainer');
$container.imagesLoaded(function () {
$container.masonry({
itemSelector:'.item'
});
});
$container.infinitescroll({
navSelector:'.navigation', // selector for the paged navigation
nextSelector:'.navigation #next', // selector for the NEXT link (to page 2)
itemSelector:'.item', // selector for all items you'll retrieve
bufferPx:40,
debug:true,
columnWidth:function (containerWidth) {
return containerWidth / 5;
},
loading:{
finishedMsg:'No more pages to load.',
img:'http://i.imgur.com/6RMhx.gif'
},
pathParse: function(path,page){
return $(this.nextSelector).attr("href");
}
},
// trigger Masonry as a callback
function (newElements) {
// hide new items while they are loading
var $newElems = $(newElements).css({ opacity:0 });
// ensure that images load before adding to masonry layout
$newElems.imagesLoaded(function () {
// show elems now they're ready
$newElems.animate({ opacity:1 });
$container.masonry('appended', $newElems, true);
});
//console.log("test (never fired :( )");
}
);
});
Now, since your next link will not update by it self (http://reddit.ymindustries.com/?after=t3_yh4av), you need to change the callback to pull out last element from ajax response and change next link... could be something like this
function (newElements) {
// hide new items while they are loading
var $newElems = $(newElements).css({ opacity:0 });
// ensure that images load before adding to masonry layout
// ======> if query parameter after=... is caring filename then do this
var lastImageUrl= $newElements[$newElements.length-1].attr("src");
var lastFileName= lastImageUrl.substring(lastImageUrl.lastIndexOf("/") +1, lastImageUrl.lastIndexOf("."));
$("#next").attr("href", "http://reddit.ymindustries.com/?after="+lastFileName);
$newElems.imagesLoaded(function () {
// show elems now they're ready
$newElems.animate({ opacity:1 });
$container.masonry('appended', $newElems, true);
});
//console.log("test (never fired :( )");
}
You also need to take care of wich version of infinite-scroll your using since if you use the ones that comes with masonry/isotope (version 2.0b2.110713), both need a little hack in order to call the function and not use the predefined array:
//old code, to be changed (line 489)
desturl = path.join(opts.state.currPage);
// new code
desturl = (typeof path === 'function') ? path(opts.state.currPage) : path.join(opts.state.currPage);
This is already fixed in the newer versions of infinite-scroll
I had the same problem with jQuery's "infinitescroll" and Masonry. You might just solve this by giving your page more initial items so that the plugin's scrolling detection kicks in.
In WordPress this is under the "Reading" settings. By default WordPress only opens 10 items at a time. You could increase that number to 100/page to be more sure the window will be full initially. I had some code here that was just horrible, turns out I just needed longer pages, not more code.
So it's difficult to test these plugins on large displays if you don't have enough images. Maybe the solution is to scale the images larger on large displays so you're more sure about getting your content below the fold.
If you think someone might get to your website with a really huge display, I'm not sure what the answer is other than showing more items/page and maybe adding $('#masonry').infinitescroll('retrieve'); to your footer to load an extra page just in case.
