I am building a mobile website. I need the header to be position:fixed (but being mobile that is not supported) so I am using iScroll4 because it seems to be what I am looking for. For some reason I am not able to figure out how to implement it.
Here is my HTML:
<html>
<head>
<!--includes the iscroll.js file-->
</head>
<body>
<div id="header">
<!--header contents-->
</div>
<div id="wrapper">
<div id="scroller">
<!--a bunch of html that you probably don't care to see-->
</div>
</div>
Here is my CSS:
#scroller {
position: absolute;
}
#wrapper {
position: absolute;
width: 100%;
top: 0px;
left: 0;
overflow: auto;
}
#header {
background: #4B92DB;
border: none;
height: 175px;
opacity: 1;
position: absolute;
left: 0;
top: 0;
width: 100%;
}
And here is my Javascript:
var myScroll;
function loaded() {
myScroll = new iScroll('wrapper');
}
document.addEventListener('touchmove', function (e) { e.preventDefault(); }, false);
If you have any ideas they would be greatly appreciated.
Where's your loaded() being called? This (or something like it) might help:
<body onload="loaded()">
Reading iScroll4 official page might help you. http://cubiq.org/iscroll-4
Section: Getting started. There are 3 ways to make it work:
onDOMContentLoaded event to trigger iscroll
onLoad event to trigger
inline, place the code below the html bit you want to scroll
All codes are just on the page mentioned.

I am using the divi theme for wordpress, I have selected the code module and I am trying to get a picture of a website to scroll when hovered over and to reverse scroll when the hover ends...therefore returning the image back to its original location. There is an image in front of the website. Basically this gives the appearance that the user is scrolling down the webpage from a computer. The idea was originally discovered at dividojo.com (Good idea dividojo!) https://www.dividojo.com/website-design/ it is located towards the bottom of the page.
I have the complete code fully functional outside of wordpress with the following code.
<!DOCTYPE html>
<html>
<head>
<title>animatingimage</title>
<link href="css/style.css" rel="stylesheet" />
<script type="text/javascript" src="jquery-3.2.1.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("#insideComputer").hover(function() {
$("#insideComputer").stop(true).animate({
marginTop:"-1210px"
}, 5000);
},
function(){
$("#insideComputer").stop(true).animate({
marginTop:"0px"
}, 5000);
});
});
</script>
</head>
<body>
<div id="bigDiv">
<img id="computer" src="img/computer3.png">
<div id="imgDiv">
<img id="insideComputer" src="img/website1.png">
</div>
</div>
</body>
</html>
and here is the attached external CSS.
#bigDiv {
background-color: #F5F5F5;
width: 500px;
height: 500px;
margin: 200px;
}
#imgDiv{
width: 463px;
height: 269px;
position: relative;
top: -430px;
left: 19px;
overflow: hidden;
}
#insideComputer {
width: 100%;
}
Like I said, the above functions appropriately. I am trying to input this into the divi theme. I have modified the above code to this:
<style>
#bigDiv {
background-color: #F5F5F5;
width: 500px;
height: 500px;
margin: 200px;
}
#imgDiv{
width: 463px;
height: 269px;
position: relative;
top: -430px;
left: 19px;
overflow: hidden;
}
#insideComputer {
width: 100%;
}
</style>
<script type="text/javascript">
$(document).ready(function(){
$("#insideComputer").hover(function() {
$("#insideComputer").stop(true).animate({
marginTop:"-1210px"
}, 5000);
},
function(){
$("#insideComputer").stop(true).animate({
marginTop:"0px"
}, 5000);
});
});
</script>
<div id="bigDiv">
<img id="computer" src="http://localhost/kaiserkreations/wp-
content/uploads/2017/08/computer3.png">
<div id="imgDiv">
<img id="insideComputer" src="http://localhost/kaiserkreations/wp-
content/uploads/2017/08/website1.png">
</div>
</div>
With all of the documentation I have read, I should be able to place this inside of the content section of the divi code module and have it work appropriately. When I place this chunk into the module, I see the image, and the formatting is appropriate, but the animation is dead. I do know that Jquery is working correctly, because when i test with an alert function it works fine.
Any ideas where I've gone wrong. I looked but was unable to find anything on stack overflow similar.
Thanks guys!
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
I have discovered that the code above does in fact work as posted. However, it appears that the current version of Jquery is not inherently included in the newest divi theme. so i simply placed it above the script posted above and it started to function. I am noticing some errors thrown in the console, however everything is functioning.
It is also working with placing the jquery embed in the head directly. I prefer this method more.
I'm currently working on an UI using HTML5 and jQuery. I try to make a load screen for my app, thus select a div in the onload event and fade it out, once the page is fully loaded.
My coding looks like this:
jQuery:
$(document).ready(myApp.init);
$(window).on("load", function () {
console.log("load");
$("div.loadScreen").fadeOut();
});
HTML:
<div class="container">
<form method="POST">
...
</form>
</div>
<div class="loadScreen">
<span>loading...</span>
</div>
CSS:
div.loadScreen {
opacity: 1;
background: #123;
width: 100%;
height: 100%;
z-index: 10;
top: 0;
left: 0;
position: fixed;
}
It shows the log message "load", but the selection of the div doesn't work.
Do you have an idea how to solve this issue?
Thanks :)
I removed the first line of your jQuery/js and it worked:
https://codepen.io/anon/pen/yXaoER?editors=1111
$(window).on("load", function () {
console.log("load");
$("div.loadScreen").fadeOut();
});
div.loadScreen {
opacity: 1;
background: #123;
width: 100%;
height: 100%;
z-index: 10;
top: 0;
left: 0;
position: fixed;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container">
<form method="POST">
...
</form>
</div>
<div class="loadScreen">
<span>loading...</span>
</div>
Hope this helped!
It seems there was no problem
$(window).on("load", function () {
console.log("load");
$("div.loadScreen").fadeOut();
});
div.loadScreen {
opacity: 1;
background: #123;
width: 100%;
height: 100%;
z-index: 10;
top: 0;
left: 0;
position: fixed;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container">
<form method="POST">
...
</form>
</div>
<div class="loadScreen">
<span>loading...</span>
</div>
in first line of code you use $(document).ready(myApp.init);, are you sure before loaded completely do any change in html file?
in your browser see console log for error that prevent to run successfully or if not seen , add more detail of your code in question.
I have a webpage that uses tubular.js script to show youtube video as a site background. There's a sentence on tubular page:
First, it assumes you have a single wrapper element under the body tag
that envelops all of your website content. It promotes that wrapper to
z-index: 99 and position: relative.
So following that, I wrote a simple html/css code:
<html>
<head>
<style>
* {
margin: 0;
padding: 0;
}
#logocontainer{
position: absolute;
top: 20%;
margin-top: -35px;/* half of #content height*/
left: 0;
width: 100%;
text-align:center;
}
#logo {
margin-left: auto;
margin-right: auto;
height: 75px;
}
</style>
<body>
<div id="wrapper" class="clearfix">
<div id="logocontainer">
<div id="logo">
<img src="img/logo.png"/>
</div>
</div>
</div> <!--wrapper-->
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript" charset="utf-8" src="js/jquery.tubular.1.0.js"></script>
<script type="text/javascript">
$(function() {
var options = {
videoId : '9JXVUP1hyxA',
start : 1
};
$('body').tubular(options);
});
</script>
</body>
</html>
but now, when I run it - I see only youtube video without my logo on top... I know the logo is there, because when I comment out the youtube script I can see it, however I don't see it when the video is present. I tried to add z-index:99 to #logo but that didn't do any magic... Can you help me with that?
EDIT:
As A. Wolff suggested below, I added to my css:
#wrapper{
z-index:99;
position: relative;
}
still though - no good results, video is still on top..
I see in their own Tubular they use this little script...
$('document').ready(function() {
var options = { videoId: 'ab0TSkLe-E0', start: 3 };
$('#wrapper').tubular(options);
// f-UGhWj1xww cool sepia hd
// 49SKbS7Xwf4 beautiful barn sepia
});
Just adding this keeps everything on top.
Use the code in this Fiddle as a sample.
Your must use z-index with position: relative/absolute.
Also your z-index in video must be less than in your blocks.
video {
position: absolute;
z-index: 1;
}
div {
position: relative;
z-index: 2;
}
How to block all UI things in a webpage until all JavaScript files including jquery.js are loaded completely. Is there any possibility to do it using only JavaScript?
You can add a css mask with z-index set to higher than all your other ui elements on the page
In your page
<body>
<div class="mask"></div>
..
..
</body>
CSS
.mask {
position: fixed;
top: 0px;
width: 100%;
height: 100%;
padding: 0px;
margin: 0px;
background: #666;
overflow: hidden;
opacity: 0.7;
z-index: 99;
}
Once your jQuery is loaded, hide this mask.
$( document ).ready(function() {
$('.mask').hide();
});
Add some kind of this snippet at the very top of you body:
<div class="loading-overlay" id="loading">
<div class="loading">Loading..</div>
</div>
and this styles inline in HEAD:
<style>.loading-overlay {
position: fixed;
top: 0;
left: 0;
width: 100%;
height: 100%;
background: rgba(0, 0, 0, .6);
z-index: 1000;
}
.loading {
font-size: 20px;
text-align: center;
color: #FFF;
position: absolute;
top: 50%;
left: 0;
width: 100%;
}</style>
Then after all javascript files execute this code:
document.getElementById('loading').style.display = 'none';
Make sure z-index property of the overlay is high enough to cover everything on the page.
However this solution is not reliable if some of your heavy scripts are loaded asynchronously.
Example: http://jsfiddle.net/ucPLW/
Statically listing the script tags in the head will ensure they are loaded before the DOM. This has been the case for as long as I can remember.
<html>
<head>
<!-- insert your script tags here -->
</head>
<body>
<!-- your DOM here -->
</body>
</html>
Its recommended to load the scripts at the bottom of the page instead so I'm not sure your motivations for this.
If by "UI Things," you mean the DOM, then you can put your javascript either at the end of your html like so:
<html>
<head>...</head>
<body>
<script>
// This javascript will execute after the HTML has loaded
</script>
</body>
</html>
Or if you want to use JQuery then you can put your UI code in a document ready function like this:
$(document).ready(function() {
// This javascript will also execute after the HTML has loaded
});
Best of Luck.
You can use the $(window).load() event for your code since this happens after the page is fully loaded and all the code in the various $(document).ready() handlers have finished running.
$(window).load(function(){
//your code here
});
I'm working on project to provide a bolt-on tool for websites, which makes heavy use of jQuery. Presentation / design is crucial, and I want to replace the standard (ugly) scrollbar applied by the browser to html elements with overflowing content, with something better looking.
There are numerous jQuery plug-ins around that apply custom scrollbars and allow styling via CSS which is great, but all the ones I've tried seem to suffer from the same problem which is this: if the scrollable content contains a form with text fields etc, tabbing between fields does not activate the scrollbar, and in some cases can screw up the custom scrollbar layout altogether.
Two examples of plug-ins I've tried:
http://manos.malihu.gr/jquery-custom-content-scroller
http://baijs.nl/tinyscrollbar/
I've tried others also, but in all demos / examples the content is plain text. I've done a lot of searching on this already, but it seems no-one has tried using these plug-ins with form-based content.
All these plug-ins seem to work in more or less the same way, and I can see exactly what happens and why, but just wondered if anyone else has had this problem and / or found a solution?
This issue can be easily replicated as follows (using the tinyscrollbar plug-in):
Add this to a standard html test page -
CSS:
<style>
#tinyscrollbartest { width: 520px; height: 250px; padding-right: 20px; background-color: #eee; }
#tinyscrollbartest .viewport { width: 500px; height: 200px; overflow: hidden; position: relative; }
#tinyscrollbartest .overview { list-style: none; position: absolute; left: 0; top: 0; }
#tinyscrollbartest .scrollbar { position: relative; float: right; width: 15px; }
#tinyscrollbartest .track { background: #d8eefd; height: 100%; width: 13px; position: relative; padding: 0 1px; }
#tinyscrollbartest .thumb { height: 20px; width: 13px; cursor: pointer; overflow: hidden; position: absolute; top: 0; }
#tinyscrollbartest .thumb .end { overflow: hidden; height: 5px; width: 13px; }
#tinyscrollbartest .thumb, #tinyscrollbartest .thumb .end { background-color: #003d5d; }
#tinyscrollbartest .disable { display: none; }
</style>
Html:
<div id="tinyscrollbartest">
<div class="scrollbar">
<div class="track">
<div class="thumb">
<div class="end"></div>
</div>
</div>
</div>
<div class="viewport">
<div class="overview">
</p>Here's a text field: <input type="text"/><p>
...
// lots of content to force scrollbar to appear,
// and to push the next field out of sight ..
...
<p>Here's another field: <input type="text"/></p>
</div>
</div>
</div>
Plug-in reference (assuming jquery libraries etc are referenced also):
<script type="text/javascript" src="scripts/jquery.tinyscrollbar.min.js"></script>
Jquery code:
<script type="text/javascript">
$(document).ready(function () {
$('#tinyscrollbartest').tinyscrollbar();
});
</script>
Now click in the first text field so it has focus, hit the tab key to move to the next one and see what happens.
I understand your problem.. But is hard to find a good solution to this. You could try to set a focus event on your form elements. And let this event trigger the scrollbar_update function of tinyscrollbar. You can set the offsetTop of the form element that currently has focus as the methods parameter. I think that would work.
$('formelements').focus(function(){
YourScrollbar.tinyscrollbar_update(this.offsetTop);
});
I had to overwrite the standard tabbing functionality with my own:
$(".scrollable").each(function() {
if (!$(this).data("scrollbar"))
{
$(this).data("scrollbar", new Scrollbar({
holder:$(this)
}));
$(this).find("input").bind("keydown", function(e)
{
var keyCode = e.keyCode || e.which;
if (keyCode == 9)
{
e.preventDefault();
var scrollTo = $(this);
if (e.shiftKey)
{
var nextInput = $(this).prevAll("input:not([type=hidden])").first();
scrollTo = nextInput.prevAll("input:not([type=hidden]), label").first();
}
else
{
var nextInput = $(this).nextAll("input:not([type=hidden])").first();
}
if (nextInput.length)
{
console.log(scrollTo);
$(this).closest(".scrollable").data("scrollbar").scrollTo(scrollTo, function()
{
nextInput.focus().select();
});
}
}
});
}
});
It's a bit annoying to have to wait for the scroll but I don't see any other option.
