go to #id by scroll buggy on iPad - ipad

Example: http://bit.ly/LWZv42
Coding a one page layout with animated scroll for Nav. Everything works perfect in desktop, but on the iPad you simply can't go back and forth by clicking the nav li links. I noticed though if you click a nav link then scroll a little down/up the page it will work.
function init_siteNav(){
function goToByScroll(id){
$('html,body').animate({scrollTop: $(id).offset().top},'slow');
}
$('.siteMenu li.home a').click(function(){
goToByScroll('body');
return false;
});
$('.siteMenu li.clients a').click(function(){
goToByScroll('#portfolioWrap');
return false;
});
$('.siteMenu li.contact a').click(function(){
goToByScroll('#contactMapHolder');
return false;
});
}
Any suggestions?

Try triggering the click on the LI element instead of the HREF. The HREF elements might be a little small for a finger on the iPad, the larger physical area the LI is producing may give you better results.
Put alerts in the click events to make sure they are being fired by the iPad.

Click on a disabled Jquery UI Slider goes to top of page

When you click on a JQuery UI slider that is disabled and the page has been scrolled down, the page goes back to the top.
This is happening because the slider widget is implemented with an anchor tag containing an Href of #.
This is my hack solution.
$(".ui-slider-disabled").on("click",
".ui-slider-handle",
function () {return false;});
It works well but, is there a native (API) way to stop this?
How about this (you may need to change the class, depending on how you set it up)
$(".ui-slider").click(function(e){
e.stopPropagation()
});

jQuery tabs + scroll to content simultaneously

This is driving me a little crazy as I just can't get it to work :(!
I have jQuery tabs set-up as follows (all working) :
$(".tabs_area" ).tabs({
fx: { duration: 'slow', opacity: 'toggle' }
});
I then have a scroll to anchor focus mechanism (again works fine in terms of the function itself) :
$('.tabs_area li a').bind('click',function(event){
var $anchor = $(this);
$('html, body').stop().animate({
scrollTop: $($anchor.attr('href')).offset().top
}, 500,'easeInOutExpo');
event.preventDefault();
});
My problem is that sadly they won't work simultaneously. When I click the tab, it correctly displays the corresponding tab content BUT it doesn't scroll you to the start of this content. You have to click the tab again for it to then do the scroll to the content, which isn't good.
Sadly the reason I need is that I am using this on a mobile website, and when you click the tab, although it does actually change the content, it is bellow the tabs menu, and therefore below the visible area of the screen, hence why I want it to swap the content then scroll you down to this so you can see it, and of course with one click only.
So I think I need to combine the scroll functionality within the tabs set-up code... somehow... as a callback or something... but I just keep breaking it :(!!
Any help would be so much appreciated.
Thanks in advance,
TJ
Why don't you use the show option for jQuery Tabs?
Seems to do what you wish to do.
Check the solution
$(".tabs_area" ).tabs({
show: function(e,ui){
$('html, body').stop().animate({
scrollTop: $(ui.tab.getAttribute('href')).offset().top
}, 500,'easeInOutExpo');
}
});

jquery Mobile scrolling and active state

I have a set of divs that can be scrolled through on my jquery mobile page. Each div has an active class in CSS so they change color when they are tapped. For some reason when I try to scroll through my list the items turn active because I am 'clicking' them.
That isn't too serious and it looks fine, but there's also another glitch. If the page is intertial scrolling, so I just flicked it and it hasn't stopped moving, a tap on the screen will activate the div I pressed when I first scrolled it.
Any idea what is causing this/how to stop it?
You could try the stopPropagation
HTML:
<div id='someID'>
<someElement />
</div>
JS:
$('#someID').click(function(e){
e.stopPropagation(); //stops default behaviour
//check to make active/inactive
if( $('#someID').hasClass('active') ){
$('#someID').removeClass('active');
//do what needs to be done when it becomes activated
} else {
$('#someID').addClass('active');
//do what needs to be done when disabled
}
//do whatever you always want to here
});
Note: whatever requires the click event to work will have to be re-enabled afterwards, though if you use a link/button/etc. within the div that has a click event, it'll still function.

Jquery Mobile 1.3 slider conflicts with panel

I am trying to set up a JQuery Mobile 1.3 site that uses a panel and a slider.
Problem is, that using the slider triggers the panel, which opens on a "swiperight" event, as I am moving the slider to the right. The slider will be for pagination, the panel for a menu.
Code here:
http://jsfiddle.net/kMARn/1/
Move the slider to the right and the panel will open.
I have tried using the .not() selector for the panel to not react on the slider:
$(document).not("#slider").on("swiperight", function(event, ui) {
$("#myPanel").panel("open");
});
But it won't work, the panel opens when i move the slider to the right. Tried a bunch of variants too, but I'm lost...
Any ideas?
Thanks!
A bit late to the party, but you can disable swipe-to-close by setting the data-swipe-close attribute to "false" on the panel div.
http://jquerymobile.com/demos/1.3.0-beta.1/docs/panels/options.html
In my case I used this simple code, without data-swipe-close = "false" in panel.
Keeping panel close with swipe right, outside of the slider.
$('#panel').find('#slider')
.on('slidestop',function(e,ui) {
var value = e.target.value;
//...operations with slider value...
})
.parent().on('swiperight',function(e,ui) {
e.stopPropagation(); //block panel close
})
From the 1.3.0b1 Docs for Swipe:
"Triggers when a horizontal drag of 30px or more (and less than 75px
vertically) occurs within 1 second duration"
This applies to and can be configured for swiperight too. You can make the slider small in length and this would ensure that both the slider event stop and the swipe are not triggered at the same time, yet that may not be practical for all scenarios.
What might be better is to bind the swipe right to a DIV or section of the page. By this, I mean if you have a 75 px div box on the left hand side of the display, and when a swipe event occurred within that div, it could trigger the menu.
I feel the logic here might be better controlled by a button, much like used in the Facebook App to display there slide out menu. In the Dolphin browser on Android, this type of event also triggers a bookmark menu, so if a page has a swiperight event and trigger it, I sometimes get both the event and the bookmark menu from the App. Annoying!
I did fork your jsfiddle and will play with it more (http://jsfiddle.net/Twisty/Hg2pw/). FYI, they have JQM 1.3.0b1 in their available frameworks so you don't have to link it in your HTML. If I find some more info, I will comment here.
The following solution is more a workaround. It should be relatively reliable though.
$(document).ready( function () {
var menu_available = true;
$(document).on("swiperight", function(event, ui) {
if (menu_available) $("#myPanel").panel("open");
});
$("#slider").on("slidestop", function( event, ui ) {
menu_available = false;
window.setTimeout(function() {menu_available= true;},250);
});
});
The variable menu_available is false for a 250 milliseconds right after the slide stops. The window.setTimeout block will reset the variable so that the menu is available again.
This is a stupid workaround, but jQuerys function event.stopEventPropagation(), which IMHO would be the correct way to go, didn't work.

How do I prevent scrolling to the top of a page when popping up a jQuery UI Dialog?

I currently use jTemplates to create a rather large table on the client, each row has a button that will open a jQuery UI dialog. However, when I scroll down the page and click on one of those buttons, jQuery dialog will open, but the scroll position get lost and the page jumps back to the top (with the blocking and the actual dialog showing off the screen). Has anyone seen or know what might cause this problem?
Thanks.
Are you using an anchor tag to implement the "button" that pops the dialog? If so, you'll want the click handler that opens the dialog to return false so that the default action of the anchor tag isn't invoked. If you are using a button, you'd also need to make sure that it doesn't submit (by returning false from the handler) and completely refresh the page.
For example,
$('a.closeButton').click( function() {
$('#dialog').dialog('open');
return false;
});
<a class='closeButton'>Close</a>
If your buttons work with an html anchor tag with href="#" replace the href for example by href="javascript:;" or any other method that you use to disable the href. The reason why the scrolling happens is because of href="#" scrolls to the top of your page.
change your code like this
$('a.closeButton').click( function(e) {
e.preventDefault();
$('#dialog').dialog('open');
});
You can try :
scrollTo(0, jQuery("body"));
