How to detect mouse down event on fabric js animated objects

i was playing with Fabric.js and aim is to detect mouse down event on an animated object. Currently images are being animated from bottom to top, and when i press mouse down it just shows coordinate but does not detect clicking on Object.
I also noticed that, when images start their animation, only then i can click/select them, after that they become non-selectable
here is a jsfiddle demo of code. please check and suggest.
my html is :
<h3>Hello Fabric</h3>
<div class="mainCanvasContainer">
<canvas class="mainCanvas" id="mycanvas" width="500px" height="400px"></canvas>
</div>
<div id='info'>
</div>
now here is my Javascript:
$(document).ready(function () {
var canvas_id = 'mycanvas';
function showInfo(text){
$('#info').append('<div> '+text+' </div>');
}
(function () {
var canvas = this.__canvas = new fabric.Canvas(canvas_id, {selection: false});
fabric.Object.prototype.originX = fabric.Object.prototype.originY = 'center';
canvas.on('mouse:down', function (options) {
if (options.target) {
showInfo('an object was clicked! ', options.target.type);
}
var cor=options.e.clientX+','+ options.e.clientY;
showInfo(cor);
});
setInterval(function () {
fabric.Image.fromURL('http://www.rashflash.com/fabricjs_animation/img.png', function (img) {
img.scale(0.2);
//img.set('left', fabric.util.getRandomInt(100, 400)).set('top', 450);
//img.movingLeft = !!Math.round(Math.random());
var text = new fabric.Text('hello', {
fontSize: 30,
originX: 'center',
originY: 'center'
});
var group = new fabric.Group([img, text]);
group.set('left', fabric.util.getRandomInt(100, 400)).set('top', 420);
canvas.add(group);
});
}, 1000);
(function animate() {
canvas.forEachObject(function (obj) {
if (!obj) {
return;
}
// obj.left += (obj.movingLeft ? -1 : 1);
obj.top -= 1;
if (obj.left > 500 || obj.top < 0) {
canvas.remove(obj);
}
});
canvas.renderAll();
fabric.util.requestAnimFrame(animate);
})();
})();
});

RashFlash, you are missing setCoords() function when you animate.
Updated function animate:
(function animate() {
canvas.forEachObject(function (obj) {
if (!obj) {
return;
}
// obj.left += (obj.movingLeft ? -1 : 1);
obj.top -= 1;
if (obj.left > 500 || obj.top < 0) {
canvas.remove(obj);
}
obj.setCoords();
});
canvas.renderAll();
fabric.util.requestAnimFrame(animate);
})();
})();
Also, updated fiddle

Previous and next image link in JavaScript

I need help for the slider on TweenMax.js
The problem:
This example has 4 images, on click each images will open in a fullscreen.
But i am not getting the previous screen link and next screen link in fullscreen.
Expected Result: once image is clicked, it should get previous image hyperlink and next hyperlink in all the sliders
Please Note : Now it is working for last image and first image.
even though i click any image
Please accept my apologies, CODE is very big !

Fabric.js Sticky Note type text wrap

I am trying to make a sticky note type utility with the fabric canvas. It will help to be used as annotators.

If you manage the sticky note as a grouped rect and text you can improve the same behavior. When you need to edit the text inside the group, you just ungroup and clone the elements, append the cloned elements to the canvas and set text as editable.
You need to handle an event like double click to handle this behavior and then handle the mousedown or other interactivity with canvas to regroup them.

http://jsfiddle.net/4HE3U/1/
Above is one fiddle that can satisfy you
Basically i have made one group of Text and Rectangle and i have added it to canvas. There is only one change you need to make is that you can take one textbox to get current sticky note text content as we can not edit text of i-text online once we are adding it any group. Currently there is no way for IText to handle the events as they are not handed down to it if it's contained in a group. I think this is also the prefered way to handle that as it would confuse the user - what if he starts to edit multiple texts. This might end up in a mess. Maybe you can rework your script a little to workaround this problems.

global javascript function is not being called onchange event of a file selection

I have a javascript function which I am calling from the onChange event of the file selection box.
function cropper(){}
When I am trying to call this function from the onchange event of the file selection it is not working. I am calling it like
<label>Upload Photo:</label>
<input type="file" id="image_file" name="picture1" onchange="cropper()"/><br>
if I change the definition of function to like below it works.
$(document).ready(function(){
$(#image_file).change(function(){
});
});
Could anyone please help me how to achieve it using the first approach. Thanks in advance.

There are few problems here
There is a syntax error cropper is not properly closed. There is a missing } at the end of the function
jQuery UI is not enabled
Your code is within load handler which means the cropper is not a global method. You need to select no-wrap body
Try
var selectImgWidth, selectImgHeight, jcrop_api, boundx, boundy, isError = false;
function cropper() {
var previewId = document.getElementById('load_img');
var thumbId = document.getElementById('thumb');
previewId.src = '';
$('#image_div').hide();
var flag = 0;
// Get selected file parameters
var selectedImg = $('#image_file')[0].files[0];
//Check the select file is JPG,PNG or GIF image
var regex = /^(image\/jpeg|image\/png)$/i;
if (!regex.test(selectedImg.type)) {
$('.error').html('Please select a valid image file (jpg and png are allowed)').fadeIn(500);
flag++;
isError = true;
}
if (flag === 0) {
isError = false;
$('.error').hide(); //if file is correct then hide the error message
// Preview the selected image with object of HTML5 FileReader class
// Make the HTML5 FileReader Object
var oReader = new FileReader();
oReader.onload = function (e) {
// e.target.result is the DataURL (temporary source of the image)
thumbId.src = previewId.src = e.target.result;
// FileReader onload event handler
previewId.onload = function () {
$("#dialog").dialog("open"); //--> this is where dialog box is opened
// display the image with fading effect
$('#image_div').fadeIn(500);
selectImgWidth = previewId.naturalWidth; //set the global image width
selectImgHeight = previewId.naturalHeight; //set the global image height
// Create variables (in this scope) to hold the Jcrop API and image size
// destroy Jcrop if it is already existed
if (typeof jcrop_api !== 'undefined') jcrop_api.destroy();
// initialize Jcrop Plugin on the selected image
$('#load_img').Jcrop({
minSize: [32, 32], // min crop size
// aspectRatio : 1, // keep aspect ratio 1:1
bgFade: true, // use fade effect
bgOpacity: .3, // fade opacity
onChange: showThumbnail,
onSelect: showThumbnail
}, function () {
// use the Jcrop API to get the real image size
var bounds = this.getBounds();
boundx = bounds[0];
boundy = bounds[1];
// Store the Jcrop API in the jcrop_api variable
jcrop_api = this;
});
};

oReader.readAsDataURL(selectedImg);
}
