Auto Scaling Image Annotation

Scalize is a jQuery plugin used for adding custom markers (hotspots) with custom popovers and animations to containers or images.
But now When I click one by one on pointer it show all one by one But I am trying to show only one so when click another pointer will close the other which already opened.
Here is my EXAMPLE
(function(jQuery) {
"use strict";

Add this to your initialisation:
getSelectorElement: function(el) {
$('.item-point.active').not($(el)[0]).find('.toggle').click();
}
This hooks into the getSelectorElement method in the Scalize plugin and triggers a click on any active (open) elements that don't match the most recently clicked item.
Add it like so:
$(document).ready(function(){
$('.scalize').scalize({
styleSelector: 'circle',
animationPopoverIn: 'fadeIn',
animationPopoverOut: 'fadeOut',
animationSelector: 'pulse2',
getSelectorElement: function(el) {
$('.item-point.active').not($(el)[0]).find('.toggle').click();
}
});
});
Note, because this is hooking into existing methods in the plugin it's a little safer (no unpredictable side effects, plus you get the intended transition out on the disappearing elements). Fiddle.

I've modified your jsFiddle to work.
TL;DR: Anytime an point is clicked, if there are other active siblings, loop over them and hide their popups.
It isn't a pretty way of doing it but it is working in the Fiddle.
$('.scalize').on('click', '.item-point', (function() {
$(this).siblings('.item-point.active').each(function() {
var popover = $(this).data('popover');
$(popover).removeClass('fadeIn').css({
'display': 'none'
});
$(this).removeClass('active');
});
}));

How to set the div height properly when image loading

I'm tring to build a grid webside,but it shows like first image when I 'm loading.So I use function getImageSize from this
Get Image height before its fully loaded to set the imageDiv height,but still failed.Would you please tell me why and how to fix it? Thanks.

How to display only one image in ezpublish JS slider

I'm a beginner php developer, and have a shockingly poor fluency in Javascript. An ezpublish website I'm working on has this slider in as a default piece of code, but it displays three items. How can I edit it to show only 1 item? The code is:
(function() {
YUI( YUI3_config ).use( 'node', 'event', 'io-ez', function(Y, result) {
Y.on('domready', function(e) {
var offset = 0;
var limit = 1;
var total = {$block.valid_nodes|count()};
var handleRequest = function(e) {
var className = e.target.get('className');
if ( className == 'carousel-next-button' ) {
offset += 1;
if ( offset > total )
offset = 0;
}
if ( className == 'carousel-prev-button' ) {
var diff = total - offset;
if( offset == 0 )
offset = 0;
else
offset -= 1;
}
var colContent = Y.Node.all('#block-3 .col-content');
colContent.each(function(n, e) {
n.addClass('loading');
var height = n.get('region').bottom - n.get('region').top;
n.setStyle('height', height + 'px');
n.set('innerHTML', '');
});
var data = 'http_accept=json&offset=' + offset;
data += '&limit=' + limit;
data += '&block_id={$block.id}';
Y.io.ez( 'ezflow::getvaliditems', { on: { success: _callBack
}, method: 'POST', data: data } );
};
var _callBack = function(id, o) {
if ( o.responseJSON !== undefined ) {
var response = o.responseJSON;
var colContent = Y.Node.all('#block-{$block.id} .col-content');
for(var i = 0; i < colContent.size(); i++) {
var colNode = colContent.item(i);
if ( response.content[i] !== undefined )
colNode.set('innerHTML', response.content[i] );
}
}
};
var prevButton = Y.one('#block-{$block.id} input.carousel-prev-button');
prevButton.on('click', handleRequest);
var nextButton = Y.one('#block-{$block.id} input.carousel-next-button');
nextButton.on('click', handleRequest);
});
});
})();
</script>
A hand with this would be great x

Looks to me like this code loads each item after the user clicks prevButton or nextButton. So the simplest way to force only a single item to display is probably to hide those buttons.
Without the markup it's hard to say what the optimal solution is, but I would try to find out what makes the particular markup you're working with into a carousel (I'd guess a class containing "carousel") and remove that so that it's just a single item without the carousel functionality.
For what it's worth, this question is not specific to eZ Publish or PHP so I'd consider removing those tags.

How to drag an image to move it smoothly on screen, using jquery in ie8

I am working on a project where we can move an image like in google map,, it works perfectly in crome,ff and above ie9, but when i checked in ie8 the image is not moving smoothly,it takes a 2 to 3 sec of time to move.
/* Map dragging */
var previousX;
var previousY;
var previousLeft;
var previousTop;
var cids = self.data.cuLocation;
var lumids = self.data.lumLocation;
$('#MapView img').css( 'cursor', 'pointer' );
$("#MapView img").mousedown(function(e) {
//console.log("mousedown");
e.preventDefault();
drag.state = true;
previousX = e.originalEvent.clientX;
previousY = e.originalEvent.clientY;
previousLeft = $("#MapView img").position().left;
previousTop = $("#MapView img").position().top;
});
$("#MapView img").mousemove(function(e) {
var old_pos = self.getPosition();
if (drag.state) {
e.preventDefault();
drag.x = e.originalEvent.clientX - previousX;
drag.y = e.originalEvent.clientY - previousY;
var cur_position = $("#MapView img").position();
var new_left = cur_position.left + drag.x;
var new_top = cur_position.top + drag.y;
previousX = e.originalEvent.clientX;
previousY = e.originalEvent.clientY;
}
});
$("#MapView img").mouseleave(function(e) {
//console.log("mouseleave");
drag.state = false;
});
$(document).mouseup(function(e) {
// alert("mouseup");
drag.state = false;
});

Javascript module pattern - what am I doing wrong?

A working version of this is here: http://est.pagodabox.com/client/svedka
I have the following function which I'm trying to convert into a module pattern, but when I try to use one of the function that I return at the bottom, for example:
est_project.closeContent($html);
I get an error that it's not a function. Is there something i'm doing wrong here?
Thanks!

The problem is that you're not executing the anonymous function, your code is the equivalent of:
var est_project = function() {};
You need to execute the function if you want it to return the functions defined in it.
Just replace the last line:
});
By:
}());
Or you can keep your code and call the closeContent function like this:
est_project().closeContent();
But I guess that's not what you want :-) You'd instantiate a new object everytime you call the est_project function.

At the start and end of your file just attach the object to window with the executed function and wrap whole function inside a self executing function. like this
(function(global) {
//your code goes here
global.est_project = est_project();
})(this)
