Attempting to get a css value with jquery

I am attempting to get a css value of a background. My attempt is failing and the correct value isn't being delivered. I have a spectrum.js color picker and no matter which color I choose rgba(0,0,0,0) is always chosen. When I look at the background in the console it displays it correctly in the DOM.
Does anybody see why this is failing?
<div class="container" id="outside-preview">
<div class="container" id="inside-preview">
<div id="image-square"></div>
</div>
</div>
$(".colorpicker").spectrum({
color: "#FFF",
showInput: true,
className: "full-spectrum",
showInitial: true,
showPalette: true,
showSelectionPalette: true,
maxSelectionSize: 10,
preferredFormat: "hex",
localStorageKey: "spectrum.demo",
change: function(color) {
var eq = $(this).index('.colorpicker');
$('.container').eq(eq).css('background-color', color.toHexString())
}
});
var color = $( "#outside-preview" ).css( "background-color" );
$("#result").html("That div is " + color + "");
Fiddle

You need to place the code which reads the CSS value in the change handler so that it updates the #result element after a selection is made. Your current code is only reading it on load.
change: function(color) {
var eq = $(this).index('.colorpicker');
$('.container').eq(eq).css('background-color', color.toHexString())
var color = $("#outside-preview").css("background-color");
$("#result").html("That div is " + color);
},

Ion.RangeSlider color from middle

I'm trying to use Ion.RangeSlider to make a slider where the color starts from the center and goes in the direction of the slider control until it hits the slider control. Right now, this is what I have:
Instead, I would like the color to go from the center of the slider to the slider control.
How can I make the RangeSlider work like that so that the color starts from the middle (as shown above)?
EDIT:
I looked at this question, but it deals with sliders with two controls instead one.
EDIT 1:
setup.js:
jQuery(document).ready(function($){
$(".slider").each(function() {
console.log($(this).attr("id"));
$(this).ionRangeSlider({
type: $(this).attr("data-slider_type"),
grid: $(this).attr("data-slider_grid"),
min: $(this).attr("data-slider_min"),
max: $(this).attr("data-slider_max"),
prefix: $(this).attr("data-slider_prefix")+" ",
postfix: " " + $(this).attr("data-slider_suffix"),
step: $(this).attr("data-slider_stepper"),
from: $(this).attr("data-slider_from")
});
$(this).on("change", function () {
var $this = $(this),
value = $this.prop("value").split(";");
});
});
});

Use: https://github.com/jordansoltman/ion.rangeSlider with has the additional boolean option: fixMiddle. For example:
$(".slider").ionRangeSlider({
fixMiddle: true,
...
});
Note: use ion.rangeSlider.js as ion.rangeSlider.min.js has not been updated.

How to load image on demand

I have this simple image zoom jQuery. Here is a Demo example. It uses the elevateZoom jQuery.
The code behind is very simple:
<img id="zoom_05" src='small_image1.png' data-zoom-image="large_image1.jpg"/>
<script>
$vc("#zoom_05").elevateZoom({
zoomType : "inner",
cursor: "crosshair"
});
</script>
My question, is how can i make the large image load on demand, only when the mouse is over it. Please have a look at this demo example and let me know what i need to add in the code.

img element (id="zoom_05") above, would not load large_image1.jpg on its own.
Large image load happens because elevateZoom() looks into its data-zoom-image value and immediately loads it. One way around this behaviour is to defer elevateZoom() until user hover's over the small image for the first time. Quick example:
jQuery( function () {
var elevate_zoom_attached = false, $zoom_05 = $("#zoom_05") ;
$zoom_05.hover(
// hover IN
function () {
if ( ! elevate_zoom_attached ) {
$zoom_05.elevateZoom({
zoomType : "inner",
cursor : "crosshair"
});
elevate_zoom_attached = true ;
};
},
// hover OUT
function () {
if ( elevate_zoom_attached) { // no need for hover any more
$zoom_05.off("hover");
}
}
);
}) ;
Mind you this is an quick, on-top-of-my-head code, but should work ...
Also in this case elevateZoom() action might not be immediate while large image loading is going on.

I used this idea to initiate zoom on any number of images on the same page by adding a zoom class to the image. It works without any HOVER OUT
<img class="zoom" src="myimage.png" data-zoom-image="mybigimage.png"/>
$('.zoom').hover(
// hover IN
function () {
var currImg = $(this); //get the current image
if (!currImg.hasClass('zoomon')) { //if it hasn't been initialized
currImg.elevateZoom(); //initialize elevateZoom
currImg.addClass('zoomon'); //add the zoomon class to the img so it doesn't re-initialize
}
})

Bootstrap + Zeroclipboard = Tooltips can't be shown on hover?

I'm trying to use ZeroClipboard for a "Click to copy" feature on an element and the same time show a bootstrap tooltip.
Unfortunately the tooltip doesn't work if I use ZeroClipboard on an element. Any help would be greatly appreciated...
// BOOTSTRAP TOOLTIP
$('.myDiv').tooltip({
title: 'Click to copy',
placement: 'right',
trigger: 'hover',
animation: true
});
// ZEROCLIPBOARD
var clip = new ZeroClipboard.Client();
clip.setHandCursor(true);
$('.myDiv').live('mouseover', function () {
clip.setText($(this).text());
if (clip.div) {
clip.receiveEvent('mouseout', null);
clip.reposition(this);
} else clip.glue(this);
clip.receiveEvent('mouseover', null);
});

Managed to get it working in a very simple way
var zero = new ZeroClipboard($el);
$(zero.htmlBridge).tooltip({title: "copy to clipboard", placement: 'bottom'});

Sometimes it is hard to get all the snippets together and to work ... this is a complete solution using ZeroClipboard 1.3.2 and Bootstrap 3.1.0:
HTML:
<a id="copycommand" href="#" data-clipboard-text="text to copy">Copy ...</a>
ZeroClipboard create a container with the ID global-zeroclipboard-html-bridge, this is the access point for the Bootstrap Tooltip.
jQuery:
// initialize Tooltip
$('#global-zeroclipboard-html-bridge').tooltip();
// ZeroClipboad
ZeroClipboard.config({ moviePath: 'ZeroClipboard.swf' });
var clip = new ZeroClipboard(document.getElementById('copycommand'));
clip.on('complete', function(client, args){
alert("Copied text to clipboard: " + args.text);
});
// settings for the Tooltip
clip.on('load', function(client) {
$('#global-zeroclipboard-html-bridge').attr({
'data-toggle':'tooltip',
'data-title': 'Tooltip text goes here ...',
'data-placement': 'bottom',
'data-html': true
});
// show the tooltip
$('#global-zeroclipboard-html-bridge').tooltip('show');
});

If you run Tooltip after ZeroClipboard it should work without problems!

Found a workaround by putting the tooltip to be shown on click for Bootstrap, but then using hooks in ZeroClipboard to show and hide it upon hover.
Here is how I did it:
$('div.color-inspiration span').tooltip({
title: 'Click to copy',
placement: 'right',
trigger: 'click',
animation: false
});
var element = null;
var clip = new ZeroClipboard.Client();
clip.setHandCursor(true);
$('div.color-inspiration span').live('mouseover', function () {
element = $(this);
clip.setText($(this).text());
if (clip.div) {
clip.receiveEvent('mouseout', null);
clip.reposition(this);
} else clip.glue(this);
clip.receiveEvent('mouseover', null);
});
clip.addEventListener( 'onMouseOver', my_mouse_over_handler );
function my_mouse_over_handler( client ) {
$(element).tooltip('show');
}
clip.addEventListener( 'onMouseOut', my_mouse_out_handler );
function my_mouse_out_handler( client ) {
$(element).tooltip('hide');
}
clip.addEventListener( 'onMouseUp', my_mouse_up_handler );
function my_mouse_up_handler( client ) {
$(element).tooltip('hide');
}

Old question but I recently encountered this problem and was able to find a solution, it's rather simple but a bit blanket. Because the flash element positions itself with a zindex of 10000 on top of whatever element you have on the page you'll have to append the flash element with a selector and title. This can be done with the ZeroClipboard callbacks.
clip.on( 'load', function(client) {
$('#global-zeroclipboard-html-bridge').attr('rel', 'tooltip').attr('title', 'Click Here To Copy URL');
} );

With Zero Clipboard 2.2 and Bootstrap 3 I got it to work like this
var $copyButton = $('.clipboard');
var clip = new ZeroClipboard($copyButton);
clip
.on('ready', function() {
$('#global-zeroclipboard-html-bridge').attr({
'data-toggle': 'tooltip',
'data-title': 'Copy to clipboard...',
'data-placement': 'right'
});
$('#global-zeroclipboard-html-bridge').tooltip({
container: 'body',
trigger: 'hover'
});
})
.on('aftercopy', function() {
$('#global-zeroclipboard-html-bridge').tooltip('hide');
});
Change the selector on line one.
the #global-zeroclipboard-html-bridge selector targets a div that is inserted by the Zero Clipboard component and that overlays the copy button.

bug is a known issue and mentioned here: Zeroclipboard bug causing issue: see # https://github.com/zeroclipboard/zeroclipboard/issues/369

Adding to #gnorsilva's answer. Here is how I set new text on the tooltip once it was copied successfully:
$(clip.htmlBridge).tooltip({
title: 'copy to clipboard',
placement: 'bottom'
});
clip.on('load', function(client) {
client.on('complete', function() {
$('.tooltip .tooltip-inner').text('copied!');
});
});
This achieves the same effect as GitHub when you click one of their ZeroClipboard elements such as copy SHA or when you click the clone URL button

Created function not found

I'm trying to create a simple function, but at runtime firebug says the function does not exist.
Here's the function code:
<script type="text/javascript">
function load_qtip(apply_qtip_to) {
$(apply_qtip_to).each(function(){
$(this).qtip(
{
content: {
// Set the text to an image HTML string with the correct src URL to the loading image you want to use
text: '<img class="throbber" src="/projects/qtip/images/throbber.gif" alt="Loading..." />',
url: $(this).attr('rel'), // Use the rel attribute of each element for the url to load
title: {
text: 'Nieuwsbladshop.be - ' + $(this).attr('tooltip'), // Give the tooltip a title using each elements text
//button: 'Sluiten' // Show a close link in the title
}
},
position: {
corner: {
target: 'bottomMiddle', // Position the tooltip above the link
tooltip: 'topMiddle'
},
adjust: {
screen: true // Keep the tooltip on-screen at all times
}
},
show: {
when: 'mouseover',
solo: true // Only show one tooltip at a time
},
hide: 'mouseout',
style: {
tip: true, // Apply a speech bubble tip to the tooltip at the designated tooltip corner
border: {
width: 0,
radius: 4
},
name: 'light', // Use the default light style
width: 250 // Set the tooltip width
}
})
}
}
</script>
And I'm trying to call it here:
<script type="text/javascript">
// Create the tooltips only on document load
$(document).ready(function()
{
load_qtip('#shopcarousel a[rel]');
// Use the each() method to gain access to each elements attributes
});
</script>
What am I doing wrong?

You are missing a ), closing the each call.
Change last line in the function declaration to
);}
