I'm currently working on a cross-browser Dropdown-Menu.
But currently I have some issues specifically on iOS 5.1 while "hovering" (means: Touching) the Main-Level Navigation links.
On iOS >= 6.0 the link action is prevented using return false and the submenu changes visibility to show and opacity to 1.
But on iOS 5.1 nothing happens. Neither the link-action nor the dropdownmenu shows.
EDIT: Code-Sample
$(function() {
if ((navigator.userAgent.match(/iPhone/i)) || (navigator.userAgent.match(/iPod/i)) || (navigator.userAgent.match(/iPad/i))) {
$("#mainNavigation ul li.dropactive > a").click(function() {
return false;
});
}
});
Any special workarounds for this iOS Safari?
Cheers,

In addition to "hover", add a "focus" selector.

Title pretty much says it all.
I'm struggling with selecting the damn fullscreen button out of the default <video> skin.
I found this on http://www.jwplayer.com/blog/using-the-browsers-new-html5-fullscreen-capabilities/:
<script type="text/javascript">
function goFullscreen(id) {
// Get the element that we want to take into fullscreen mode
var element = document.getElementById(id);
// These function will not exist in the browsers that don't support fullscreen mode yet,
// so we'll have to check to see if they're available before calling them.
if (element.mozRequestFullScreen) {
// This is how to go into fullscren mode in Firefox
// Note the "moz" prefix, which is short for Mozilla.
element.mozRequestFullScreen();
} else if (element.webkitRequestFullScreen) {
// This is how to go into fullscreen mode in Chrome and Safari
// Both of those browsers are based on the Webkit project, hence the same prefix.
element.webkitRequestFullScreen();
}
// Hooray, now we're in fullscreen mode!
}
</script>
<img class="video_player" src="image.jpg" id="player"></img>
<button onclick="goFullscreen('player'); return false">Click Me To Go Fullscreen! (For real)</button>
I see you're probably looking for the native player's selector, but this will let you create your own button.
Want to apply HTML 5 fullscreen APi to background image of div
<div class="bgimg" style="background-image:url('img/home-1.jpg')" />
<img src="img/fullscreen.png" id="fullscreen-btn">
</div>
I want onclick fullscreen-btn background image of div bgimg ie home-1.jpg should open in fullscreen. I tried below code but not workin Kindlt suggest
<scritpt>
$(function() {
var bg = $('.bgimg');
$('#fullscreen-btn').click(function () {
goFullScreen(bg.attr('style', 'background-image:url()'));
});
});
function goFullScreen( element )
{
if ( element === undefined )
{
// If no element defined, use entire document
element = document.documentElement;
}
if ( element.requestFullScreen )
{
// Spec, supported by Opera 12.1+
element.requestFullScreen();
}
else if ( element.mozRequestFullScreen )
{
// Supported by Firefox 10+
element.mozRequestFullScreen();
}
else if ( element.webkitRequestFullScreen )
{
// Supported by Chrome 15+ & Safari 5.1+
element.webkitRequestFullScreen();
}
// Still no IE support, sorry folks :(
}
Seems to be working for me. You just needed to add the image path in your javascript with quotes around it.
$(function() {
var bg = $('.bgimg');
$('#fullscreen-btn').click(function () {
goFullScreen(bg.attr('style', "background-image:url('img/home-1.jpg')"));
});
});
FIDDLE
I believe, but will admit am not 100% sure, that the fullscreen API can only full screen an HTML element. So that is why it will fullscreen div.bgimg but will not fullscreen the background image of the element. <img> is an HTML element, however, so I would think that would work. Is there any reason you would not want to use that instead of setting the background image of your divs?
If so, you could try to wire up some JS that connects visible divs with the background images (Like what you have now) to invisible images and load those to your fullscreen script instead.
I'm having a similar problem as described in this question, but with JQuery Mobile 1.4, particularly with the list views. A slight tap that is not enough to be considered a click causes list elements to highlight and stay highlighted:
Can anyone tell me how I can prevent any hover highlighting in my application? I would rather not have to modify any of the JQM theming CSS to do this, but I will if that is what it takes.
It looks like maybe there is a jquery hover event or mouseover being triggered to set the interaction state to something like ".ui-state-hover" or ".state-hover"
1.
jQueryUI - removing class on hover
2.
function overPrevent(e){
e.preventDefault();
return false;
}
$(".options li").hover(overPrevent,outOption);
// alternative to above but still using JavaScript
$(".options li").click(function() {
$(this).removeClass("ui-state-focus ui-state-hover");
}
// alternative to above but still using JavaScript
$(".options li").hover(function(e){
$(this).removeClass("ui-state-hover");
});
OR maybe unbind to the mouseenter and mouseleave?
3.
$('.options li').click(function(){
$(this).unbind("mouseenter mouseleave");
})
OR try a pure css override
4.
.theme-group-header .state-default .corner-all .state-hover:hover{
background:none;
}
also detecting mobile up front with something like this small library - http://detectmobilebrowsers.com/
then you can name space your css and override the jquery ui library with something roughly like this:
.touch{
.theme-group-header .state-default .corner-all .state-hover:hover{
background:none;
}
}

To prevent any hover highlighting in a jQuery Mobile 1.4 Listview you can overwrite the appropriate CSS according to the swatch you're using:
/* Button hover */
#yourList.ui-group-theme-a .ui-btn:hover {
background-color: #f6f6f6 /*{a-bhover-background-color}*/;
}
/* Button down */
#yourList.ui-group-theme-a .ui-btn:active {
background-color: #e8e8e8 /*{a-bdown-background-color}*/;
}
here is the code : http://jsfiddle.net/yuliantoadi/hMr7h/
if you try to hover the 'test 2' link, the dropdown menu will appear. the problem in IE 6, any idea how to make this dropdown menu work in IE 6?
In IE 6, :hover only works on a tags for CSS. If you want hover effects for IE 6, they'll have to be done in Javascript.
you could use some JS to work around.
jquery sample:
$(function(){
$('.link ul li').hover(
function(){
$(this).addClass('hover');
},function(){
$(this).removeClass('hover');
});
});
http://jsfiddle.net/hMr7h/1/
That's because IE 6 (and 7, if my memory serves) doesn't support the :hover pseudo-class on anything but a link.
You can, however, emulate the behavior with a bit of JavaScript (not using jQuery, unlike choise's answer):
var element = document.getElementById('someid'); // I'm leaving this part up to you.
element.onmouseover = function (e) {
element.className += ' hover';
};
element.onmouseout = function (e) {
elemen.className.replace(' hover','');
};
A friend and myself are trying to workaround IE (7/8). We have built a canonical example here:
http://www.mathgladiator.com/share/ie-select-bug-hover-css-menus.htm
Using a CSS menu, we would like to have selects in them. However, in IE, the menu goes away when you interact with the select box. We believe this has to do with a bug in how selects affect events.
Is there a workaround? At least with pure CSS or DOM hacks?
I do not think there is a pure CSS way around this. This is due to a very common bug to the way IE handles events on select elements.
You can however work around it with Javascript:
<script type="text/javascript">
$(document).ready(function () {
$('.nav_element a').mouseover(function() {
$('.submenu').hide();
$(this).parent().find('.submenu').show();
});
$('.submenu').mouseover(function() {
$(this).show();
});
$('.submenu').mouseout(function (e) {
// Do not close if going over to a select element
if (e.target.tagName.toLowerCase() == 'select') return;
$(this).hide();
});
});
</script>
The code above uses jQuery.
Here is a way to improver select behavior in IE7/8, but it does not fix the issue
Change DOCTYPE
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
Add script
<script>
function ddlOut(e) {
setTimeout(function() { e.className = e.className.replace(' over', ''); }, 1000)
}
</script>
Add css
#nav .over div.submenu
{
display: block;
}
#nav .nav_element{
behavior: expression(
this.onmouseover = new Function("this.className += ' over'"),
this.onmouseout = new Function("ddlOut(this)"),
this.style.behavior = null
);
}
It will work better at least but of course not perfect.
My advice is to change select control to html equivalent. I use OboutDropDown that has a nice view. There are many implementations that can suite you needs.
First you need to expand the :hover surface underneath your menu.
So in your css add width:310px;height:220px to #nav .nav_element a.
(also add a class or an id on the second div styled with top:220px)
Now you just need to simulate a mousedown triggered when you click on the select which will halt when the selection between the options is done - you can probably do the last part if you check for the onfocus state of the select which will stop the mousedown.
