The issue is that, if drag the black square and the mouse off the red square area, the black square follows mouse's movement once move the mouse back to the red square area. How to fix that? like once the mouse of side of the red square area then trigger mouseup?

I've updated your code http://jsfiddle.net/5tpPx/3/
added a class dragoff when leaving the parent container and removing it only when the mousedown event it fired again.
Also checked if handle has class dragoff before setting its coords.

Clearly there's a typo in this script. It says:
.one('mouseup', function() {
$(this).off('mousemove.draggable');
$draggable.css('z-index', z);
});
But should be:
.on('mouseup', function() {
$(this).off('mousemove.draggable');
$draggable.css('z-index', z);
});

I have a question about the topic.
I use stackover at the first time.
I use JS wookmark plugin. by the way I make web pages.
One of pages with sidebar with open and close.
When I close the left sidebar, It makes a space left of article.
Usually It resizes width on no space. The open sidebar size is 260px. The close size is 70.
I use these but no action.
$(document).ready(function() {
var article_list = $("#grid-container article").get();
var outer = $('<div class="grid-outer"></div>').get(0);
var nowbox = false;
for ( var i = 0; i < article_list.length; i++ ) {
if($(article_list[i]).hasClass('area')){
nowbox = false;
$(outer).append(article_list[i]);
}
if($(article_list[i]).hasClass('area-box')) {
if(!nowbox) {
nowbox = $('<div class="gridbox"></div>').get(0);
$(outer).append(nowbox);
}
$(nowbox).append(article_list[i]);
}
}
$("#grid-container").empty();
$("#grid-container").append(outer);
var options = {
offset: 20, // Optional, the distance between grid items
autoResize: true,
fillEmptySpace: true,
};
var resizeTimer = null;
var gridarr = [];
var gridboxlist = $('.gridbox').get();
for ( var i = 0; i < gridboxlist.length; i++ ) {
gridarr[i] = new Wookmark( gridboxlist[i], options);
}
resize();
resizeTimer = setTimeout(function() {
resize();
}, 0);
$(window).resize(function(){
clearTimeout(resizeTimer);
resize();
resizeTimer = setTimeout(function() {
resize();
}, 0);
})
function resize(){
var gridboxlist = $('.gridbox').get();
$(gridboxlist).each(function(){
var window_w = window.outerWidth;
var outer_w = $(this).width();
if( window_w < 1400) {
var w = Math.floor((( outer_w - ( 20 * 1 )) / 2));
$(this).find('.area-box').css({
'width': w+'px'
});
} else {
var w = Math.floor((( outer_w - ( 20 * 2 )) / 3));
$(this).find('.area-box').css({
'width': w+'px'
});
}
});
if( 0 < gridarr.length ){
refresh();
}
}

I want to make a rectangular move by click on a button and stop it clicking on the same button. Here is a part of my code:
document.getElementById("startStop").addEventListener("click", changePlace);
function changePlace() {
nIntervMove = setInterval(movement, 100);
};
var tmp1 = 0;
function movement() {
var oElem = document.getElementById("colorRectangular");
oElem.getPropertyValue = tmp1;
tmp1 += "10px";
};
function stopMove(){
clearInterval(nIntervMove);
};
Pretty straight forward:
var makeMove = function(x, hx, t, complete) {
var target = document.getElementById('rect'),
dx = 0,
d = setInterval(function() {
target.style.left = dx + "px";
dx += hx;
if(dx >= x) {
clearInterval(d);
complete();
}
}, t);
};
makeMove(100, 5, 500, function() {
alert('done');
});

You can achieve this by simply ignoring the mousemove and mouseup event handlers by either not initializing them or using flags to indicate that you are in stamp mode.
All you need is:
canvas.onmousedown = function(e) {
var pos = getMousePos(e);
render(pos.x, pos.y);
}
That's it, and it works similar for touch events.
To use flag (I would not recommend adding and removing handlers all the time):
var isStampMode = true;
canvas.onmousemove = function(e) {
if (isStampMode) return;
...
}
and similar for mouse up (but not really necessary unless it depends on what you do in mousedown).

Hope this helps!
I'm looking for a javascript charting API that would allow user to dynamically modify value points (through drag'n drop) and then provide some callbacks to get those new values.
