I'm trying out iScroll and following the documentation, but for some reason I can't get it to initialize. At least, I don't think I can. From the demos and code, I'm not exactly sure what I should expect it to look like!
I've got this code:
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Index</title>
<script src="~/Scripts/iScroll/iscroll.js"></script>
<script type="text/javascript">
var myScroll;
function loaded() {
myScroll = new IScroll('#scroll', {
mouseWheel: true,
scrollbars: true
});
}
</script>
</head>
<body onload="loaded()">
<div id="scroll">
<div>...Lots of Lorem Ipsum text here...</div>
</div>
</body>
</html>
For the sake of tidiness, I've not included the actual text I've got in the div I want to scroll, but all I've got is lots and lots of text - enough to make the page need to scroll. The reference to the iScroll file is definitely correct, even with its mixed cases.
I added in the options (mouseWheel and scrollbars) just to try and make something happen so that I could determine whether the script was being initialized. Setting scrollbars to false doesn't seem to make any difference. Bizarrely, if I set mouseWheel to false my mousewheel works, but if I set it to true it doesn't - exactly the opposite of the documentation.
I'm clearly doing something wrong, but I can't see what - it doesn't get more basic than what I'm trying. I looked at the barebone example from the documentation, but that doesn't seem to work for me either, in that there are no scrollbars displayed anywhere. I'm getting the same behaviour in Chrome (48) and IE11.

I am trying to build a simple webpage that replaces the contents of the <div id="body"> with something new based on the user clicking on a "link"
The following code does exactly what I expect in Chrome and Firefox, but does nothing (except turn the link to the visited color) in IE 10 or 11:
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("#activities").click(function(){
$("#body").load("test02.html");
});
});
</script>
</head>
<body>
<div id="header">
Activities
<!-- this stays the same -->
</div>
<div id="body">
<p>this is the content that arrives without needing prompting</p>
<!-- All content will be loaded here dynamically -->
</div>
<div id="footer">
<!-- this stays the same -->
</div>
</body>
</html>
This is the content of "test02.html":
<p>---</p>
<p>Hello world!</p>
<p>---</p>
I've checked the javascript security settings in IE and everything is set to "enable." I've also tried adding type="text/javascript" to the script tags.
Some amount of Googling has turned up the possible need to reinstall IE, which I have tried.
Anyone have an idea about how to get this working in IE?
The problem is that IE breaks itself in "compatibility" mode. The way in which it breaks itself in this case is failing to correctly look up your div id="body" element. I think that was observation error on my part, I think the real problem is addEventListener (because jQuery 2.x doesn't fall back to attachEvent anymore, since it doesn't support IE8 and earlier [or the "compatibility" modes that act like them]):
I can replicate the problem. The problem goes away if I tell IE not to break itself (e.g., not to use compatibility mode) by adding this to the top of the head element:
<meta http-equiv="X-UA-Compatible" content="IE=Edge" />
IE's default for intranet sites is to display them in "compatibility" mode.
At one point I wasn't at all sure that when in "compatibility" mode it didn't get confused about that element with the id "body". IE has a history of getting confused by things like that. So you might also consider the-body or similar, but I tested and didn't seem to need it.
Side note: You probably also want to add a return false or e.preventDefault() to your click handler, so it doesn't follow the # link (which will scroll back to the top of the page and add # to the address bar).
add meta tag below to your page
<meta http-equiv="X-UA-Compatible" content="IE=edge;chrome=1" />
Do you mean <body> tag or <div id="body"> and do you ever try preventing default behavior of the link by using this below code :
$(document).ready(function(){
$("#activities").click(function( e ){
e.preventDefault(); //<---- add here
$("#body").load("test02.html");
});
});
I'm attempting to use the Stellar.js script to apply a parallax effect.
Here is the official example from Mark Dalgleish's website
http://markdalgleish.com/projects/stellar.js/demos/backgrounds.html
Even when I copy and paste the source code from the example, instead of having a slight scroll effect to each one image, they appear in fixed positions.
What am I doing wrong?
1.
If even the Demo code does not work, check whether you gave the jquery or stellar.js path correctly.
You can check it in browser console, if you have any errors. The console will print it, if it can't load the resource.
2.
If the paths correct, check if you run the initialisation for stellar, when the page loaded, or if you gave "data-stellar-background-ratio" attribute for the right elements. If you give '0' to the data-stellar-background-ratio it won't scroll either.
Note that, it won't work on mobile devises either.
3.
If you checked everything above, and it still doesn't work, try to insert the scripts at the end of the element. Sometimes it helps.
Something like this:
<html>
<head>
<!-- Title, CSS, and other stuff -->
</head>
<body>
<!-- Content here with right stellar attributes -- >
...
<!-- At the end of body load the scripts, and run initialisation -->
<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
<script src="YOUR_PATH_TO_STELLAR/jquery.stellar.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(window).stellar({
scrollProperty: 'scroll',
horizontalScrolling: false,
positionProperty: 'position'
});
</script>
</body>
</html>
I had a situation where my stellar.js parallax scrolling wouldn't initialize until my browser window was resized. I found the $.stellar('refresh'); seemed to fix the issue. (Using AngularJS)
angular.module('ForeverLeather').controller('HomeCtrl', ['$scope', function($scope) {
$(window).stellar({
horizontalScrolling: false,
verticalOffset: 0,
horizontalOffset: 0,
responsive: true,
}).stellar('refresh');
}]);

Plugin implementation issue with jQuery
(1 answer)
Closed 9 years ago.
Here is my problem. There's a nifty looking plugin here http://lab.smashup.it/flip/ which flips things around. I managed to implement it, but for some odd reason I'm only getting the first half of the animation rendered, the second part is just invisible (or hidden) and then it jumps to the end. To make things even more fun, everything was working fine at some point but then suddenly not. I of course backtracked as far back as possible back to when things were fine, and same problem again. I can't seem to locate the source of the problem. If someone could just please help me out by testing out the plugin and telling me if they managed to get a full animation rendered. For my HTML I based it on the source code of the plugin demo page to make sure, but to no avail.

For those of you who recognize this problem, I did try to avoid posting a new thread until I was advised to do so as no one was reading the old post. I've also flagged my initial post for deletion.
Nothing wrong with the basics of what you posted, I set up a quick fiddle and it worked fine, but that was when I noticed that you have not included your JS correctly. I think the issue is with that.
First you are pulling in jQuery from google using google.load. Then you are getting a (potentially different) version from jQuery.com. Also, flip relies on jQuery UI, and I can't see you importing that anywhere in the html snippet you posted.
Why don't you try this and get rid of the google.load and jQuery.com sources and see if that works.
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>

This plugin depend's on jquery and jqueryUI, include both in your code
I used to be able to get hold of
$('[data-role=header]').first().height()
in alpha with jQuery 1.5.2, but no longer can in beta with jQuery 1.6.1. Has something changed?
Full code - this writes 0 to console.log...
<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no"/>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.0b1/jquery.mobile-1.0b1.min.css" />
<script type="text/javascript" src="http://code.jquery.com/jquery-1.6.1.min.js"></script>
<script type="text/javascript"
src="http://code.jquery.com/mobile/1.0b1/jquery.mobile-1.0b1.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
console.log($('[data-role=header]').first().height());
});
</script>
</head>
<body>
<div data-role="page" id="home">
<div data-role="header">
<h1>Header</h1>
</div>
<div data-role="content">
//lots of code
</div>
</div>
</body>
</html>
However, change this to jQuery 1.5.2 and jQuery Mobile alpha:
<script type="text/javascript" src="http://code.jquery.com/jquery-1.5.2.min.js"></script>
<script type="text/javascript" src="http://code.jquery.com/mobile/1.0a4/jquery.mobile-1.0a4.min.js"></script>
and it writes the non-zero height of the header div.
Incidentally, it is also non-zero with jQuery 1.6.1 but without jQuery Mobile. So it's something to do with the jQuery Mobile rendering.
Can't see anything in the release notes to suggest what might have happened, but I'm no jQuery expert.
The change that is causing the difference is "Responsive design helper classes: Now deprecated"
We include a set of responsive design helper classes designed to make it easy to build a responsive design that adapts the layout for various screen widths. At the time, we went with a system of dynamically appended min- and max-width classes on the body that are updated on load, resize and orientation change events as a workaround for the limitation that Internet Explorer doesn’t support media queries.
Basically, the page is getting min-height set to the current page height in the beta which is overriding the .landscape { min-height: 300px; } in the alpha.
It looks like you need to use CSS Media Queries if you want a page layout that changes or you could just add CSS style="height:43px" on the the header if you need a fixed height.
Seems like the page is not ready when you query the height(). There is no document.ready for jQuery.mobile. It doesn't explain why there is a difference between alpha and beta, but I guess a code path changed that exposed the issue.
Wrapping the query in a different event, returns the height as expected.
$("div:jqmData(role='page')").live('pageshow',function(){
console.log($('[data-role=header]').first().height());
});
I found this by examining the offsetHeight of the DOM element in the Chrome console which was non-zero but, as you reported, the height() was always reporting 0. I then created an link when clicked output the height and it was non-zero. I then realised that the height() was being called before the page was fully ready.
Relevant - jQuery mobile $(document).ready equivalent
Looks like they did change some of the syntax, Docs:
http://jquerymobile.com/demos/1.0b1/docs/api/methods.html
When finding elements by their jQuery
Mobile data attribute, please use the
custom selector :jqmData(), as it
automatically incorporates namespaced
data attributes into the lookup when
they are in use. For example, instead
of calling $("div[data-role='page']"),
you should use
$("div:jqmData(role='page')"), which
internally maps to $("div[data-"+
$.mobile.ns +"role='page']") without
forcing you to concatenate a namespace
into your selectors manually.
Try this:
$("div:jqmData(role='header')").first().height()
How to use jquery cookies in showing/hiding elements in a page ? I got the plugin from here
Tried some method but i am not successful. I used slideUp() and slideDown() functions to show/hide elements.
When a element is slided up a cookie should be set. when the page is refreshed, the element should be in slided up position
How to apply cookie when slided up and how to get the cookie when page is refreshed ?
I need help !
I think the following is what you're looking for. Let me know if I am mistaken. Good luck!
http://jsfiddle.net/8VCJY/8/
- EDIT -
Sorry! My cookies were getting set backwards. It does work now (new link). Again, all apologies.
- EDIT -
Actually, I don't even know if it does work. It looked like it did, but then reviewing my code, I can't see how that could be right. All in all, I'm pretty sure that the setting of the cookie at the appropriate time and whatnot will at least get you on the right path. I think my usage of the plugin is wrong, to be honest (I've never used it before), but I gave it what I could. I hope it was at least somewhat useful to you.
Would this do the trick?
