I am playing around with the HTML5 features, and I want div's (and similar containers like articles, sections, etc.) to be draggable. Consider the following code:
<!DOCTYPE html>
<html>
<head>
<title>A Simple Draggable Object</title>
</head>
<body>
<h1>Test #1: A Simple Draggable Object</h1>
<div draggable="true">This text should be draggable.</div>
</body>
</html>
I tested in OS X the following browsers:
In Chrome 7.0 and Safari 5.0.2 I can successfully drag the text around, but in Firefox 3.6 and 4.0b6 I can neither drag the text nor mark it (as if it was usual text). Is this a bug or a feature?
How do I achieve that Firefox lets me drag around these tags without using jQuery ?
According to HTML5 Doctor, this won't work in Firefox without some JS help.
The HTML 5 spec says it should be as
simple as adding the following
attributes to the markup of the
elements in question:
draggable="true"
However, this doesn’t work completely
for Safari or Firefox. For Safari you
need to add the following style to the
element:
[draggable=true] {
-khtml-user-drag: element;
}
This will start working in Safari, and
as you drag it will set a default,
empty value with the dataTransfer
object. However, Firefox won’t allow
you to drag the element unless you
manually set some data to go with it.
To solve this, we need a dragstart
event handler, and we’ll give it some
data to be dragged around with:
var dragItems = document.querySelectorAll('[draggable=true]');
for (var i = 0; i < dragItems.length; i++) {
addEvent(dragItems[i], 'dragstart', function (event) {
// store the ID of the element, and collect it on the drop later on
event.dataTransfer.setData('Text', this.id);
});
}

IE 'contenteditable' implemntation is not allowing me to change the cursor property when ever the contenteditable property in CKEditor is set to 'true'(no issue if the contenteditable='false').
Not an issue in chrome in both cases whether the contenteditable is set to true/false.
tried to change it dynamically using the following code but was not successful
var element = $('iframe').contents().find('body.cke_show_borders').get(0);
var elem = CKEDITOR.dom.element.get( element );
elem.setStyle('cursor', 'pointer');
any idea to handle this please?
Thanks.
It is browser native bug.
You can reproduce this issue outside of CKEDITOR with following code:
<body style="cursor:pointer" contenteditable="true">
</body>
I doubt there are any workarounds for this.
I have a webpage that uses an iframe to embed another one of our websites. However, FireFox is having issues rendering the contents of the iframe. When I inspected the raw html that was in the DOM, I noticed the following DOM structure inside the iframe:
#document
<!DOCTYPE html>
<html>
<body></body>
<head> … </head>
<body> … </body>
</html>
Notice the body tag above the head tag - that's not in the source DOM! Removing it from within the developer tools fixes all of the rendering issues. For some reason, FireFox is adding a second body tag just before the head tag. Here is my puzzle:
The extra body is not in the source HTML being delivered
The extra tag only shows up in FireFox, Chrome and IE do not have it in there iframes
If I go straight to the url the iframe is loading in FireFox, the extra body tag is not there!
I have no addons - FireFox install is clean
I have the latest FireFox as of this post (v24.0)
Does anyone know what could be causing this? The site being embedded is really simple and does not have any javascript that could be adding this extra tag.
I don't know what causes this to happen in some FF iframes and not others, but if you have access that allows you to change the code of the page that is loaded into the iframe, you could add this script that removes the first empty body tag:
<script type="text/javascript">
var ffFixCount = 0,
clearExtraBody = function(){
var bodies = document.getElementsByTagName("body");
if(bodies.length > 1){
// assumes the empty, extra body tag you want to remove is the first one
bodies[0].parentNode.removeChild(bodies[0]);
window.clearInterval(ffBodyFixer);
}else{
ffFixCount++;
}
if(ffFixCount = 20){
window.clearInterval(ffBodyFixer);
}
};
//check for extra body tag will run every 100ms,
// 20 times, or, for 2 seconds (to give time for bug to happen)
// or will stop if extra body tag is found
var ffBodyFixer = window.setInterval(
function(){
window.clearExtraBody();
}, 100);
</script>
I'm trying to make a feature where users type into a text box which produces suggestions as you type (like Google Instant), then those suggestions can be dragged into boxes on the page. It all worked fine until I discovered touch screen mobile devices don't work with HTML 5 drop and drag. I'm trying to get it work with jquery instead but it's not going smoothly.
The code below displays a draggable image and it works with touch screens and mice.
<script type='text/javascript' src='js/head.min.js'></script>
<link rel='stylesheet' type='text/css' href='css/style.css' />
<script>
head.js('https://ajax.googleapis.com/ajax/libs/jquery/1.7.0/jquery.min.js','js/ui.js','js/touch.js', function (){
$('#touchme1').draggable({revert:true});
$('#drop').droppable({
drop: function( event, ui ) {
$(ui.draggable).remove();
$(this).css({'border':'#777 dashed 3px','background':'#eee'});
},
over: function(event, ui) {
$(this).css({'border':'#a33 dashed 3px','background':'#faa'});
},
out: function (event, ui){
$(this).css({'border':'#777 dashed 3px','background':'#eee'});
}
});
});
</script>
<img src='itemimages/75.jpg' id='touchme1' class='touchBox'>
The problem is that when the same code is used within the php file which is called to display search results, the drag and drop doesn't work on mobile devices (but it does on desktops).
I have a feeling you may need to attach an event handler to the #touch1 element. The code you posted only looks for #touch1 elements that already exist in the DOM, but as your element is loaded though AJAX, it will not be in the DOM when the page first loads.
You can use .on() to attach an event handler to the object.
$(document).on('mouseover', '#touchme1', function(){
$(this).draggable({revert:true});
});
In the above example I am using the mouseover event. However you will need to choose an event hander that will work for you with both touch devices and with a mouse.

With the Windows Phone 7 Browser, when the user clicks a link, it is shaded with a gray rectangle for approximately 0.5 seconds. This is fine in generally, however, if you have dynamic page behaviour, for example, clicking a link updates the DOM so that the link is no longer visible, the opaque gray rectangle lingers on the screen after the link itself has gone.
This looks pretty horrible!
Does anyone know how to disable this effect?
Add a meta tag in you head section in you html file.
<meta name="msapplication-tap-highlight" content="no" />
It should work.
The following solution seems to work (at least on the emulator). The gray shading needs the dimensions of the clicked element. If the element has zero width then there is no shading, while clicking the child elements still fires the element's click handler.
<div id="myLink" style="float:left">
<img src="images/myLinkIcon.png" style="position:absolute" />
<span style="position:absolute;left:50px">Click here</span>
</div>
<script>
// jQuery
$(function () {
$("#myLink").click(function () {
console.log("clicked on myLink");
});
});
</script>
The div can either float or be absolutely positioned. The child elements have to be absolutely positioned, otherwise the div acquires a width.
This works try using jquery
$(id|classname|document).live('click',function(){
//write code that needs to executed in this area
});
I have used this in my project. It works fine to hide the grey shade, avoid using inline function in html pages ... using jquery this function works only when inner content is assigned to it.. eg
<div id="d1"><div id="d2"></div></div>
you can this for inner div like this
$('#d2").live('click',function(){changecolor();changebackground();});
enjoy coding........jquery
The solution is to make 2 DIVs. Main div dont have width/height and this DIV is firing event and DIV inside have got size.
I've made with my friends working example inside phonegap project. Check link: https://github.com/sellupp/cordova-for-windows-phone-7-antidepressant
You are looking for: 1. gray area on tap

I have a strange result happening when loading a Partial View using jQuery Ajax into the DOM, but only when viewing the result using IE8.
The Partial View in question (for example purposes only) looks like this;
<aside>Example test</aside>
When the result comes back from the Ajax call it appears to look exactly as above. However when viewing the DOM using the developer tools in IE8 the result looks like this;
<aisde/>
Example test
</aside/>
As a result the element is not recognised and the text does not sit within it. Also the style sheet class for 'aside' is not being applied. This only happens in IE8 as far as I can see.
Any one got any suggestions, other than do not use custom tags?
Thanks in advance
You need to make sure the DOM recognizes HTML5 elements. Essentially you will have to do:
document.createElement('aisde');
Have a look at this link. Without creating the element older IE browsers will not see or style the elements.
The common practice around these issues is to load a html5 fix javascript file within a conditional comment block. The script does a createElement on all new html5 node types.
<!--[if lte IE 8]>
<script src="html5.js" type="text/javascript"></script>
