How to show child radwindow on its parent radwindow manually? - javascript

I am creating two radwindow dialogs: a parent and its child.
Parent radwindow has size 1082x630
Child radwindow has size 1500x900
On parent radwindow dialog, when I click on button "Show Child Dialog", its child radwindow will be shown.
The problem here is the size of child dialog larger than its parent. So, I want to resize the size of child dialog and show it in the center of its parent dialog.
And here is my code in Javascript that I use for resizing child dialog manually. To center child dialog, I also use childRadWindow.left and childRadWindow.top . BUT, it does not work as my expected. The child dialog does not place in the center of its parent.
Please reference my expected, actual images and my code to get the problem.
My expected result:
Actual result:
Here is my code to resize child dialog manually. I put it on child dialog *.aspx
<script type="text/javascript">
$(document).ready(function () {
resizeRWndDialog();
});
</script>
function resizeRWndDialog() {
var radWindows = [];
var radWindow = GetRadWindow();
while (true) {
if (radWindow != undefined && radWindow != null) {
radWindows.push(radWindow._popupElement);
radWindow = radWindow.BrowserWindow.GetRadWindow();
} else {
break;
}
}
var numsOfRadWindow = radWindows.length - 1;
if (numsOfRadWindow > 0) {
for (var i = numsOfRadWindow; i > 0; i--) {
var parentWindow = radWindows[i];
var parentWidth = parentWindow.clientWidth; //parentWidth =1082
var parentHeight = parentWindow.clientHeight; //parentHeight = 630
var chidWindow = radWindows[i - 1];
var childWidth = chidWindow.clientWidth; //childWidth = 1500
var childHeight = chidWindow.clientHeight; //childHeight = 900
var rateMinWidth = 0,
rateMinHeight = 0,
rateMaxWidth = 0,
rateMaxHeight = 0;
if (chidWindow.style.minWidth != "") {
rateMinWidth = parseInt(chidWindow.style.minWidth) / childWidth;
}
if (chidWindow.style.minHeight != "") {
rateMinHeight = parseInt(chidWindow.style.minHeight) / childHeight;
}
if (chidWindow.style.maxWidth != "") {
rateMaxWidth = parseInt(chidWindow.style.maxWidth) / childWidth;
}
if (chidWindow.style.maxHeight != "") {
rateMaxHeight = parseInt(chidWindow.style.maxHeight) / childHeight;
}
if ((parentWidth - 40) > 0 && childWidth >= parentWidth - 40) {
childWidth = parentWidth - 40; //parentWidth = 1082, childWidth = 1042
}
if ((parentHeight - 80) > 0 && childHeight >= parentHeight - 80) {
childHeight = parentHeight - 80; //parentHeight = 630, childHeight = 550
}
setSizeRWndDialog(chidWindow.getElementsByClassName("rwTable")[0], rateMinWidth * childWidth, rateMinHeight * childHeight, rateMaxWidth * childWidth, rateMaxHeight * childHeight, childWidth, childHeight);
setSizeRWndDialog(chidWindow, rateMinWidth * childWidth, rateMinHeight * childHeight, rateMaxWidth * childWidth, rateMaxHeight * childHeight, childWidth, childHeight);
chidWindow.left = Math.round((parentWidth - childWidth) / 2, 0) + "px";
chidWindow.top = Math.round((parentHeight - childHeight) / 2, 0) + "px";
chidWindow.focus();
radWindows[i - 1] = chidWindow;
}
}
}
function setSizeRWndDialog(element, minWidth, minHeight, maxWidth, maxHeight, width, height) {
if (minWidth != 0 && minHeight != 0) {
element.style.minWidth = minWidth + "px";
element.style.minHeight = minHeight + "px";
}
if (maxWidth != 0 && maxHeight != 0) {
element.style.maxWidth = maxWidth + "px";
element.style.maxHeight = maxHeight + "px";
} else {
element.style.maxWidth = width + "px";
element.style.maxHeight = height + "px";
}
element.style.width = width + "px";
element.style.height = height + "px";
}

I solved the problem myself, guys.
I just added one more line at the end of the resizeRWndDialog() as the snippet code below:
function resizeRWndDialog() {
//.........
if (numsOfRadWindow > 0) {
//...........
}
GetRadWindow().center(); // >> Just use this line
}

JavaScript Css Animation

I have a Javascript animation at http://dev17.edreamz3.com/css/
All code works, however, there are performance problems. on Desktop, its good, On mobile things are so slow that it's unusable. I want to optimize the animation so that it runs smoothly on mobile. It can take 20 seconds or more for the animation to render.
Right now the way the code is designed is in js/anim.js there is a render() function that gets executed every time a scroll event happens. The problem is that this routine is not efficient, that's what I think of. Each time render() executes it loops through all the paths and sections of the maze and redraws them, is there any alternative way or a strategy to get it working both on mobile as well as desktop.
var offPathTime = 1000;
window.offSection = -1;
function render() {
// var top = ($window.scrollTop() + (0.4 * $window.height())) / window.scale;
var top = ($('.parent-div').scrollTop() + (0.4 * $('.parent-div').height())) / window.scale;
top -= 660;
top /= mazeSize.h;
if (window.offSection != -1) {
$body.addClass("blockScroll");
$('.parent-div').addClass("blockScroll");
// var wtop = $window.scrollTop() / window.scale;
var wtop = $('.parent-div').scrollTop() / window.scale;
wtop -= 660;
wtop /= mazeSize.h;
var $offSection = $("#offSection" + window.offSection);
var $section = $("#section" + window.offSection);
$(".section").removeClass("sectionActive");
$offSection.addClass("sectionActive");
$section.addClass("sectionActive");
var sTop = 200 -(mazeSize.h * (window.offSections[window.offSection].cy - wtop));
$container.animate({
left: 290 -(mazeSize.w * window.offSections[window.offSection].cx) + "px",
top: sTop + "px"
}, offPathTime);
// Path
var lr = offPaths[window.offSection].x1 > offPaths[window.offSection].x0;
var dx = Math.abs(offPaths[window.offSection].x1 - offPaths[window.offSection].x0);
var dashw = (dx * mazeSize.w) | 0;
$offPaths[window.offSection].css("width", "0px");
$offPaths[window.offSection].show();
if (lr) {
$offPaths[window.offSection].animate({
width: dashw + "px"
}, offPathTime);
} else {
var x0 = offPaths[window.offSection].x0 * mazeSize.w;
var x1 = offPaths[window.offSection].x1 * mazeSize.w;
$offPaths[window.offSection].css("left", x0 + "px");
$offPaths[window.offSection].animate({
width: dashw + "px",
left: x1 + "px"
}, offPathTime);
}
return;
}
$body.removeClass("blockScroll");
$('.parent-div').removeClass("blockScroll");

if ($container.css("top") != "0px") {
$container.animate({
left: "-1550px",
top: "0px"
}, 500);
}

var path0 = paths[0];
var path1;
var inPath = 0;
var i;
var curTop = 0;
var found = false;
for (i=0; i<paths.length; i++) {
var top0 = (i == 0) ? 0 : paths[i-1].y;
var top1 = paths[i].y;
if (top >= top0 && top < top1) {
pathIdx = i;
path1 = paths[i];
inPath = (top - top0) / (top1 - top0);
found = true;
if (i > 0) {
var dy = paths[i].y - paths[i-1].y;
var dx = paths[i].x - paths[i-1].x;
var vert = dx == 0;
if (vert)
$paths[i-1].css("height", (dy * mazeSize.h * inPath) + "px");
$paths[i-1].show();
}
} else if (top >= top0) {
path0 = paths[i];
var dy = paths[i].y - top0;
var vert = dy != 0;
if (i > 0) {
if (vert)
$paths[i-1].css("height", (dy * mazeSize.h) + "px");

}
// Check for an active section
$(".section").removeClass("sectionActive");
var section;
for (i=0; i<sections.length; i++) {
var d = Math.abs(sections[i].cy - (top - 0.05));
if (d < 0.07) {
var $section = $("#section" + i);
$section.addClass("sectionActive");
}
}
}
1) At the very least - assign all DOM objects to variables outside of the function scope. Like this:
var $parentDiv = $('.parent-div');
var $sections = $(".section");
...
function render() {
...
2) Also you should probably stop animation before executing it again, like this:
$container.stop(true).animate({
...
If you are running render() function on scroll - it will run many times per second. stop() helps to prevent it somewhat.
3) If it will not be sufficient - you can switch from jQuery to Zepto(jQuery-like api, but much faster and uses css transitions for animations) or to Velocity(basically drop-in replacement for jQuery $.animate and much faster than original) or even to GSAP - much more work obviously, but it is very fast and featured animation library.

JavaScript Magnifying glass

I built a magnifying glass in JavaScript, which works well when I click on it or click and dragging it, but it should not hide from the screen.
$(".menu-left-preview-box-preview").bind('click', function (e) {
window.location = "page" + ($(this).index() + 1) + ".html";
});
var native_width = 0;
var native_height = 0;
var magnifyIsMouseDown = false;
$(".magnify").parent().mousedown(function (e) {
magnifyIsMouseDown = true;
});
$(".magnify").mousemove(function (e) {
if (magnifyIsMouseDown) {
if (!native_width && !native_height) {
var image_object = new Image();
image_object.src = $(".small").attr("src");
native_width = image_object.width;
native_height = image_object.height;
} else {
var magnify_offset = $(this).offset();
var mx = e.pageX - magnify_offset.left;
var my = e.pageY - magnify_offset.top;
if (mx < $(this).width() && my < $(this).height() && mx > 0 && my > 0) {
$(".large").fadeIn(100);
} else {
$(".large").fadeOut(100);
}
if ($(".large").is(":visible")) {
var rx = Math.round(mx / $(".small").width() * native_width - $(".large").width() / 2) * -1;
var ry = Math.round(my / $(".small").height() * native_height - $(".large").height() / 2) * -1;
var bgp = rx + "px " + ry + "px";
var px = mx - $(".large").width() / 2;
var py = my - $(".large").height() / 2;
$(".large").css({ left: px, top: py, backgroundPosition: bgp });
}
}
}
});
$(".magnify").parent().mouseup(function (e) {
magnifyIsMouseDown = false;
$(".large").fadeOut(100);
});
$(".magnify").parent().mouseleave(function (e) {
$(".large").fadeOut(100);
});
manageSlide();
By default the magnifying glass must be there on the screen. The magnifying glass can be dragged and after it's dropped it must remain there at it's dropped position.
On clicking and dragging the magnify glass is working well, but it should not hide from the screen. It should be there on screen.
Provide handle of magnify glass with that circle (in design).
Working example: http://jsfiddle.net/mohsin80/4ww8efx5/
I replaced the if (magnifyIsMouseDown) { by if (isDragging) { and created the following methods:
var isDragging = false;
$(".magnify").parent().mouseup(function(e) {
isDragging = false;
});
$(".magnify").parent().mousedown(function(e) {
isDragging = true;
});
To make a simulated drag event with jQuery.
Here is the fiddle. Hope it helped :)

Move absolute positioned divs off eachoter

I'm attempting to output on a page multiple 'labels' over an image using absolute positioned divs. Each of these divs has a unique number and are placed according to an x and y position on the map (these are percentage based so the image may be scaled).
As some of these labels may overlap, I need a way to either stop them from overlapping, or to essentially 'bump' them off eachother so they no longer overlap. (At this point, it doesn't matter if they are not in their correct position as long as they are near enough as there is a separate 'Pin' view).
They need to stay within the confines of their container and not overlap with eachother.
HTML:
<div id="labelzone">
<div class="label" style="left:0%;top:8%">001</div>
<div class="label" style="left:0%;top:11%">002</div>
<div class="label" style="left:1%;top:10%">003</div>
</div>
CSS:
#labelzone{
float:left;
width:500px;
height:500px;
border: 1px solid black;
position: relative;
}
.label{
position:absolute;
border:1px solid black;
background-color:white;
}
Jsfiddle: https://jsfiddle.net/79cco1oy/
There's a simple example of what I have as an output, these pins could be placed anywhere and there is no limit to how many is on the page, however there shouldn't be any occasion where there are too many to fit in the area.
I'm toying around with doing some form of collision detection and currently attempting to figure out an algorithm of some sort to get them to no longer overlap, and ensure they also don't overlap another item.
My solution is a bit more object oriented.
One object (LabelPool) will contain labels and will be in charge of storing and accomodating them so that they don't collide. You can customize the x/y values that you want to add/substract of the Label's positions in order to avoid their collision. The other object (Label) defines a Label and has some convenient methods. The collision algorithm that I used in LabelPool was taken from this post
var Label = function ($el) {
var position = $el.position(),
width = $el.outerWidth(true),
height = $el.outerHeight(true);
this.getRect = function () {
return {
x: position.left,
y: position.top,
width: width,
height: height
};
};
this.modifyPos = function (modX, modY) {
position.top += modY;
position.left += modX;
updatePos();
};
function updatePos() {
$el.css({
top: position.top,
left: position.left
});
}
};
var LabelPool = function () {
var labelPool = [];
function collides(a, b) {
return !(((a.y + a.height) < (b.y)) || (a.y > (b.y + b.height)) || ((a.x + a.width) < b.x) || (a.x > (b.x + b.width)));
}
function overlaps(label) {
var a = label.getRect();
return labelPool.some(function (other) {
return collides(a, other.getRect());
});
}
this.accomodate = function (label) {
while (labelPool.length && overlaps(label)) {
label.modifyPos(0, 1);// You can modify these values as you please.
}
labelPool.push(label);
};
};
var labelPool = new LabelPool;
$(".label").each(function (_, el) {
labelPool.accomodate(new Label($(el)));
});
Here's the fiddle.
Hope it helps.
Using js and jquery, you can find a basic collision engine based on left/top abs position and size of the label.
https://jsfiddle.net/Marcassin/79cco1oy/6/
Every time you want to add a Label, you check if the positionning is overlaping any existing div, in this case, you translate the new Label to position. This operation may not be the most beautiful you can find, there can be a long process time in case of lots of labels.
$(document).ready (function () {
addLabel (0, 8);
addLabel (0, 11);
addLabel (1, 10);
addLabel (2, 7);
});
function addLabel (newLeft, newTop)
{
var newLab = document.createElement ("div");
newLab.className = "label";
$(newLab).css({"left": newLeft+"%", "top": newTop + "%"});
var labels = $("#labelzone > div");
newLab.innerHTML = "00" + (labels.length + 1); // manage 0s
$("#labelzone").append (newLab);
var isCollision = false;
var cpt = 1;
do
{
isCollision = false;
$(labels).each (function () {
if (! isCollision && collision (this, newLab))
isCollision = true;
});
if (isCollision)
$(newLab).css({"left": (newLeft + cpt++) + "%",
"top": (newTop + cpt++) + "%"});
} while (isCollision);
}
function isInside (pt, div)
{
var x = parseInt($(div).css("left"));
var y = parseInt($(div).css("top"));
var w = $(div).width () + borderWidth;
var h = $(div).height ();
if (pt[0] >= x && pt[0] <= x + w &&
pt[1] >= y && pt[1] <= y + h)
return true;
return false;
}
function collision (div1, div2)
{
var x = parseInt($(div1).css("left"));
var y = parseInt($(div1).css("top"));
var w = $(div1).width () + borderWidth;
var h = $(div1).height ();
var pos = [x, y];
if (isInside (pos, div2))
return true;
pos = [x + w, y];
if (isInside (pos, div2))
return true;
pos = [x + w, y + h];
if (isInside (pos, div2))
return true;
pos = [x, y + h];
if (isInside (pos, div2))
return true;
return false;
}
Here's another implementation of collision detection close to what you asked for. The two main goals being:
move vertically more than horizontally (because boxes are wider than tall)
stay within a reasonable range from the origin
Here goes:
function yCollision($elem) {
var $result = null;
$('.label').each(function() {
var $candidate = $(this);
if (!$candidate.is($elem) &&
$candidate.position().top <= $elem.position().top + $elem.outerHeight() &&
$candidate.position().top + $candidate.outerHeight() >= $elem.position().top) {
$result = $candidate;
console.log("BUMP Y");
}
});
return $result;
}
function xCollision($elem) {
var $result = null;
$('.label').each(function() {
$candidate = $(this);
if (!$candidate.is($elem) &&
yCollision($elem) &&
yCollision($elem).is($candidate) &&
$candidate.position().left <= $elem.position().left + $elem.outerWidth() &&
$candidate.position().left + $candidate.outerWidth() >= $elem.position().left) {
$result = $candidate;
console.log("BUMP X");
}
});
return $result;
}
function fuzzyMoveY($elem, direction) {
var newTop = $elem.position().top + $elem.outerHeight() / 4 * direction;
// stay in the canvas - top border
newTop = (newTop < 0 ? 0 : newTop);
// stay in the canvas - bottom border
newTop = (newTop + $elem.outerHeight() > $("#labelzone").outerHeight() ? $("#labelzone").outerHeight() - $elem.outerHeight() : newTop);
// stay close to our origin
newTop = (Math.abs(newTop - $elem.attr("data-origin-top")) > $elem.outerHeight() ? $elem.attr("data-origin-top") : newTop);
$elem.css({'top': newTop});
}
function fuzzyMoveX($elem, direction) {
var newLeft = $elem.position().left + $elem.outerWidth() / 4 * direction;
// stay in the canvas - left border
newLeft = (newLeft < 0 ? 0 : newLeft);
// stay in the canvas - right border
newLeft = (newLeft + $elem.outerWidth() > $("#labelzone").outerWidth() ? $("#labelzone").outerWidth() - $elem.outerWidth() : newLeft);
// stay close to our origin
newLeft = (Math.abs(newLeft - $elem.attr("data-origin-left")) > $elem.outerWidth() ? $elem.attr("data-origin-left") : newLeft);
$elem.css({'left': newLeft});
}
function bumpY($above, $below) {
if ($above.position().top > $below.position().top) {
$buff = $above;
$above = $below;
$below = $buff;
}
fuzzyMoveY($above, -1);
fuzzyMoveY($below, 1);
}
function bumpX($left, $right) {
if ($left.position().left > $right.position().left) {
$buff = $right;
$right = $left;
$left = $buff;
}
fuzzyMoveX($left, 1);
fuzzyMoveX($right, -1);
}
$('.label').each(function() {
$(this).attr('data-origin-left', $(this).position().left);
$(this).attr('data-origin-top', $(this).position().top);
});
var yShallPass = true;
var loopCount = 0;
while (yShallPass && loopCount < 10) {
yShallPass = false;
$('.label').each(function() {
var $this = $(this);
$collider = yCollision($this);
if ($collider) {
bumpY($this, $collider);
yShallPass = true;
}
});
loopCount++;
}
console.log("y loops", loopCount);
var xShallPass = true;
var loopCount = 0;
while (xShallPass && loopCount < 10) {
xShallPass = false;
$('.label').each(function() {
var $this = $(this);
$collider = xCollision($this);
if ($collider) {
bumpX($this, $collider);
xShallPass = true;
}
});
loopCount++;
}
console.log("x loops", loopCount);
This is not production code obviously but please report back if it helps.

Parallax H1 and H2

Can someone tell me how to adjust this .js? I want it to be able to apply on H1 and H2 with an ID in my html. Now it is only working on css background-image. Below is the .js I'm using. I'm a beginner with javascript;)
Hope you guys can help me out!
(function( $ ){
var $window = $(window);
var windowHeight = $window.height();
$window.resize(function () {
windowHeight = $window.height();
});
$.fn.parallax = function(xpos, speedFactor, outerHeight) {
var $this = $(this);
var getHeight;
var firstTop;
var paddingTop = 0;
//get the starting position of each element to have parallax applied to it
$this.each(function(){
firstTop = $this.offset().top;
});
if (outerHeight) {
getHeight = function(jqo) {
return jqo.outerHeight(true);
};
} else {
getHeight = function(jqo) {
return jqo.height();
};
}
// setup defaults if arguments aren't specified
if (arguments.length < 1 || xpos === null) xpos = "50%";
if (arguments.length < 2 || speedFactor === null) speedFactor = 0.1;
if (arguments.length < 3 || outerHeight === null) outerHeight = true;
// function to be called whenever the window is scrolled or resized
function update(){
var pos = $window.scrollTop();
$this.each(function(){
var $element = $(this);
var top = $element.offset().top;
var height = getHeight($element);
// Check if totally above or totally below viewport
if (top + height < pos || top > pos + windowHeight) {
return;
}
$this.css('backgroundPosition', xpos + " " + Math.round((firstTop - pos) * speedFactor) + "px");
});
}
$window.bind('scroll', update).resize(update);
update();
};
})(jQuery);
It should be background-position. Can you try changing?
$this.css('background-position', xpos + " " + Math.round((firstTop - pos) * speedFactor) + "px");
