Image zoom for Mootools - javascript

I whant to include image zoomer like that http://www.magictoolbox.com/magiczoom/ in my page, but I don't found any similar library for mootools. Here its my page image look like:
I tried this:
http://mootools.net/forge/p/zoomer
But it zooms inner image (not near it) and break all my images design (images is cetered by width and height)
here is my fiddle: http://jsfiddle.net/94PLv/

OPTION 1:
Zooming inside the image div
DEMO HERE
You need something like:
document.getElements('.inner a').addEvent('click', function (e) {
e.stop();
dragit = this.getElement('img').makeDraggable();
this.getElement('img').removeClass('max_limit');
});
I fixed your fiddle a bit, is this what you were looking for? I removed some of your inline CSS and added Mootools More so you can have drag instead of scrollbars.
Added also
document.getElements('.fotoDiv .inner img').addClass('max_limit');
document.getElements('.fotoDiv .inner img').setProperty('style','');
to "put things back" on the next thumb click.
OPTION 2:
using Louper plugin
DEMO HERE
Code added:
//NEW ADDED
document.getElements('.inner a').addEvent('click', function(event) {
event.stop();
});
var loupe = {
src: 'http://img.artlebedev.ru/studio/us/2009/loup.png',
x: 101,
y: 102,
radius: 85
};
document.getElements('a.click').addEvent('click', function(event) {
var id = this.getProperty('rel');
var target_el = document.id('im_' + id).getElement('img');
new Louper(target_el, {
big: target_el.src,
radius: 80,
loupe: loupe,
onReady: function() {
this.loupeWrapper.setStyles({
left: this.smallSize.width - this.loupeSize.width + 60,
top: this.smallSize.height - this.loupeSize.height + 120
});
}
});
});

Putting HTML code on JointJS link

I have worked with JointJS now for a while, managing to create elements with HTML in them.
However, I am stuck with another problem, is it possible to place HTML code, like
href, img etc, on a JointJS link and how do I do this?
For example, if I have this link, how do I modify it to contain HTML:
var link = new joint.dia.Link({
source: { id: sourceId },
target: { id: targetId },
attrs: {
'.connection': { 'stroke-width': 3, stroke: '#000000' }
}
});
Thank you!
JointJS doesn't have a direct support for HTML in links. However, it is possible to do with a little bit of JointJS trickery:
// Update position of our HTML whenever source/target or vertices of our link change:
link.on('change:source change:target change:vertices', function() { updateHTMLPosition(link, $html) });
// Update position of our HTML whenever a position of an element in the graph changes:
graph.on('change:position', function() { updateHTMLPosition(link, $html) });
var $html = $('<ul><li>one</li><li>two</li></ul>');
$html.css({ position: 'absolute' }).appendTo(paper.el);
// Function for updating position of our HTML list.
function updateHTMLPosition(link, $html) {
var linkView = paper.findViewByModel(link);
var connectionEl = linkView.$('.connection')[0];
var connectionLength = connectionEl.getTotalLength();
// Position our HTML to the middle of the link.
var position = connectionEl.getPointAtLength(connectionLength/2);
$html.css({ left: position.x, top: position.y });
}
Bit of an old question, but thought I'd add some more ideas. You can add extra svg markup to the label in a link if you like by extending the link object and then setting attributes where needed. For example:
joint.shapes.custom.Link = joint.dia.Link.extend({
labelMarkup: '<g class="label"><rect /><text /></g>'
});
This code overrides the markup for the label, so you can add extra elements in there. You can also update attributes on these elements by:
link.attr('text/text', "new text");
However hyperlinks won't work (at least I haven't got them working in Chrome) and I believe this is because Jointjs listens for all events in the model. So what you should do is use inbuilt events in Jointjs to listen for connection clicks:
paper.on('cell:pointerclick', function(cellView, evt, x, y){
console.log(cellView);
});

Google Maps API V3 Add a button near to a polygon hovered

I'm working with Google Maps API V3, and I'd like to display a clickable image near to a drawed polygon when the mouse hovers it.
Until now, I'm able to create this event, but I have no idea how to display this image near to my polygon. Ideally, I'd like this image appears where the mouse entered in the polygon.
Here is a piece of my code, but it's just a try and the image is not displayed, so it is very incomplete (and maybe wrong). You can suggest me to do otherwise, Javascript is not my preferred language...
google.maps.event.addListener(polygon, 'mouseover', function(e) {
this.setOptions( {fillOpacity: 0.1} );
polygon["btnMyButtonClickHandler"] = {};
polygon["btnMyButtonImageUrl"] = MyImage;
displayMyButton(polygon);
});
function displayMyButton(polygon) {
var path = polygon.getPath();
var myButton = getMyButton(path.btnMyButtonImageUrl);
if(myButton.length === 0)
{
console.log("IN"); //Is displayed in the console
var myImg= $("img[src$='http://linkToMyImage.png']");
myImg.parent().css('height', '21px !important');
myImg.parent().parent().append('<div style="overflow-x: hidden; overflow-y: hidden; position: absolute; width: 30px; height: 27px;top:21px;"><img src="' + path.btnMyButtonImageUrl+ '" class="myButtonClass" style="height:auto; width:auto; position: absolute; left:0;"/></div>');
// now get that button back again!
myButton = getMyButton(path.btnMyButtonImageUrl);
myButton.hover(function() {
$(this).css('left', '-30px'); return false; },
function() { $(this).css('left', '0px'); return false; });
myButton.mousedown(function() { $(this).css('left', '-60px'); return false;});
}
// if we've already attached a handler, remove it
if(path.btnDeleteClickHandler)
myButton.unbind('click', path.btnMyButtonClickHandler);
myButton.click(path.btnMyButtonClickHandler);
}
function getMyButton(imageUrl) {
return $("img[src$='" + imageUrl + "']");
}
Thanks for your suggestions !
EDIT
#MrUpsidown, unfortunately no, click event can't be a solution, I really need your Something here div appears at mouseover.
I modified your code like this :
google.maps.event.addListener(polygonPath, 'mouseover', function (event) {
if( $("#map_overlay").css('display') == "none")
{
$("#map_overlay").css({
'position': 'absolute',
'display': 'block',
'left': event.Sa.pageX,
'top': event.Sa.pageY
});
}
});
The div appears when my mouse enter the polygon and don't move except if my mouse hovers the div (which hovers the polygon). On this case, the event seems called continuously. How can we avoid this and let the div at its inital position once the mouse enter the polygon ?
Here is your modified : fiddle
You need to create an element to hold your clickable image. Make it position:absolute; with a bigger z-index than your map container. To place it at a specific place, check the mouse position on your polygon mouseover event and set the element position accordingly. Hope this helps.
Edit: Yes, wrap it in a DIV is a good idea. Here is a simple fiddle to show the concepts. And sorry, of course it was mouseover and not mouseenter like I first wrote.

Optimize sliding/collapsible sidebar

I customize a collapsible sidebar from this article
(http://devheart.org/articles/jquery-collapsible-sidebar-layout/) for my own project But it looks a bit funky and not right.
Please take a look at the project here:
http://jsbin.com/oliluz/45
The sidebar seems animating properly, but the #mainContent isn't animating along with the sidebar. It's toggling in stiffly and harsh.
Also advice if the way i added my code are optimize.
Thanks!
The new width of the #mainContent is determined by CSS; which is why it isn't animated. To animate the width of the mainContent as well, try the following:
Remove the following line from the CSS:
#wrap.sidebar #mainContent { margin-right: 270px; }
Modify the JavaScript to add the appropriate animations:
// Variables
var objMain = $('#wrap'), objSidebar = $('#sidebar');
var objContent = $('#mainContent'); // << ADDED
// Show sidebar
function showSidebar(){
objMain.removeClass('nosidebar');
objMain.addClass('sidebar');
objSidebar.animate({ 'right' : '0'},'slow');
objContent.animate({ 'margin-right': 270}, 'slow'); // << ADDED
$.cookie('sidebar-pref2', 'use-sidebar', { expires: 30 });
}
// Hide sidebar
function hideSidebar(){
objMain.removeClass('sidebar');
objMain.addClass('nosidebar');
objSidebar.animate({ 'right' : '-254px'},'slow');
objContent.animate({ 'margin-right': 0}, 'slow'); // << ADDED
$.cookie('sidebar-pref2', null, { expires: 30 });
}

Todays Special: How is this done? Is there a jquery plugin or product to do it?

I saw this technique at the bottom of a web page where the TAB stays in place at the bottom of the page and can be opened and closed to display more info. I assume it can be rotated to display a different special for different days. Can you point me to anything like it or explain the technique ? thanks. Here is a sample: http://www.tmdhosting.com/ look at the bottom of the page .
position: fixed is how you manage to keep something at the bottom or top of the page, regardless of scrolling.
This is easily discoverable using firebug's (http://getfirebug.com/) inspect element feature
You can check out my version of this at uxspoke.com
I wrote a jQuery plugin to do it, and calling it is straightforward:
$('#about').pulloutPanel({open:true}).
click(function() { $(this).trigger('toggle'); }) });
I basically instrument the panel to support "open", "close" events, and the implement the appropriate animations around them. The only "hard" part is getting the height right. It also supports "toggle" so you can add a generic click handler to it to open or close it. Finally, it uses opened/closed classes to keep track of its current state. That's it!
The code's pretty coupled to the technologies on the page (Csster) and the design it is in, so I'm not sure it will work for you. You can either use Csster, or just put the CSS rules into your stylesheet and remove them from the code. The important Css attributes are the positioning and bottom.
Here it is:
$.fn.pulloutPanel = function(options) {
var settings = $.extend({}, {
attachTo: 'bottom',
css: {
left: 0,
minHeight: 390,
border: '1px 1px 1px 0 solid #666',
has: [roundedCorners('tr', 10),boxShadow([0,0], 10, phaseToColor('requirements').saturate(-30).darken(50))],
cursor: 'pointer'
}, options);
return $(this).each(function() {
var $this = $(this);
$this.addClass('pullout_panel');
$this.bind('open', function(event) {
$this.animate({bottom: 0}, 'slow', 'easeOutBounce', function() {
$this.removeClass('closed').addClass('opened');
$this.trigger('opened');
});
});
$this.bind('close', function(event) {
var height = $this.innerHeight();
$this.animate({bottom: -height + 50}, 'slow', 'easeOutBounce', function() {
$this.addClass('closed').removeClass('opened');
$this.trigger('closed');
});
});
$this.bind('toggle', function(event) {
$this.trigger($this.hasClass('opened') ? 'close' : 'open');
});
once(function() {
Csster.style({
'.pullout_panel': {
position: 'fixed',
bottom: 0,
has: [settings.css]
}
});
});
$this.trigger(settings.open ? 'open' : 'close');
});
};

Shade entire page, unshade selected elements on hover

I'm trying to make a page inspection tool, where:
The whole page is shaded
Hovered elements are unshaded.
Unlike a lightbox type app (which is similar), the hovered items should remain in place and (ideally) not be duplicated.
Originally, looking at the image lightbox implementations, I thought of appending an overlay to the document, then raising the z-index of elements upon hover. However this technique does not work in this case, as the overlay blocks additional mouse hovers:
$(function() {
window.alert('started');
$('<div id="overlay" />').hide().appendTo('body').fadeIn('slow');
$("p").hover(
function () {
$(this).css( {"z-index":5} );
},
function () {
$(this).css( {"z-index":0} );
}
);
Alternatively, JQueryTools has an 'expose' and 'mask' tool, which I have tried with the code below:
$(function() {
$("a").click(function() {
alert("Hello world!");
});
// Mask whole page
$(document).mask("#222");
// Mask and expose on however / unhover
$("p").hover(
function () {
$(this).expose();
},
function () {
$(this).mask();
}
);
});
Hovering does not work unless I disable the initial page masking. Any thoughts of how best to achieve this, with plain JQuery, JQuery tools expose, or some other technique? Thankyou!
What you can do is make a copy of the element and insert it back into the DOM outside of your overlay (with a higher z-index). You'll need to calculate its position to do so, but that's not too difficult.
Here is a working example.
In writing this I re-learned the fact that something with zero opacity cannot trigger an event. Therefore you can't use .fade(), you have to specifically set the opacity to a non-zero but very small number.
$(document).ready(function() { init() })
function init() {
$('.overlay').show()
$('.available').each(function() {
var newDiv = $('<div>').appendTo('body');
var myPos = $(this).position()
newDiv.addClass('available')
newDiv.addClass('peek')
newDiv.addClass('demoBorder')
newDiv.css('top',myPos.top+'px')
newDiv.css('left',myPos.left+'px')
newDiv.css('height',$(this).height()+'px')
newDiv.css('width',$(this).width()+'px')
newDiv.hover(function()
{newDiv.addClass('full');newDiv.stop();newDiv.fadeTo('fast',.9)},function()
{newDiv.removeClass('full');newDiv.fadeTo('fast',.1)})
})
}
Sorry for the prototype syntax, but this might give you a good idea.
function overlay() {
var div = document.createElement('div');
div.setStyle({
position: "absolute",
left: "0px",
right: "0px",
top: "0px",
bottom: "0px",
backgroundColor: "#000000",
opacity: "0.2",
zIndex: "20"
})
div.setAttribute('id','over');
$('body').insert(div);
}
$(document).observe('mousemove', function(e) {
var left = e.clientX,
top = e.clientY,
ele = document.elementFromPoint(left,top);
//from here you can create that empty div and insert this element in there
})
overlay();
