clear javascript. dynamically created div resize: it only grow! why?

clear javascript. dynamically created div resize: it only grow! why? - javascript

First off, the whole code is here, on pastebin.
No jquery or alikes are employed!
I have a HTML with a DIV created using document.createElement("div") and plugged into the page with document.getElementById('p').appendChild(d);
The new DIV is provided with a bunch of event handlers:
var d = document.createElement('div');
d.className = 'rect';
d.addEventListener('mousedown', catch_box, false);
d.addEventListener('mouseup', release_box, false);
d.addEventListener('mouseout', release_box, false);
d.addEventListener('mousemove', mouse_move_box, false);
d.addEventListener(wheel_hook, scroll_box, false);
document.getElementById('p').appendChild(d);
This works fine:
// move the box around on 'mousemove'
var lPos = cache.left + m_speed * cache.h_dir,
tPos = cache.top + m_speed * cache.v_dir,
ok = (lPos >= 0) && ((lPos + cache.width) <= max_width) &&
(tPos >= 0) && ((tPos + cache.height) <= max_height);
if (ok) {
box.style.left = lPos + 'px';
box.style.top = tPos + 'px';
}
but this doesn't:
// resize the box
var hSize = cache.width + s_speed * cache.h_dir,
vSize = cache.height + s_speed * cache.v_dir,
ok = (hSize >= min_width) &&
((cache.left + hSize) <= max_width) &&
(vSize >= min_height) &&
((cache.top + vSize) <= max_height);
if (ok) {
box.setAttribute('style', 'width:'+hSize+'px;height:'+vSize+'px;');
box.style.width = hSize + 'px';
box.style.height = vSize + 'px';
}
The box.style.width and box.style.height may only grow :(
The question is: WHY?? And how to work it around?

JavaScript AddEventListener exceptions

At the moment, this code is working perfectly for me:
function click(event){
var header = document.getElementById('header');
var text = document.createElement('textarea');
text.multiline = true;
text.cols = 30;
text.rows = 6;
text.style.cssText = "position: absolute; margin-left:" + event.clientX + "px; margin-top:" + (event.clientY - 50) + "px;";
header.parentNode.insertBefore(text, header.nextSibling);
}
document.addEventListener("click", click);
But I'm wondering if you can stop it from activating when you click on the text area.

Test the target-node using event.target.nodeName
function click(event) {
if (event.target.nodeName.toUpperCase() !== 'TEXTAREA') {
var header = document.getElementById('header');
var text = document.createElement('textarea');
text.multiline = true;
text.cols = 30;
text.rows = 6;
text.style.cssText = "position: absolute; margin-left:" + event.clientX + "px; margin-top:" + (event.clientY - 50) + "px;";
header.parentNode.insertBefore(text, header.nextSibling);
}
}
document.addEventListener("click", click);
<header id='header'>Header</header>

How to show child radwindow on its parent radwindow manually?

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
}

Add close button to popup

How do add a close button to the following popup by putting a cross on the target page?
Currently it closes if I click anywhere outside the box, but would prefer a Cross "X" on the box or the corner.

</script>
Page opens with this link
<a class="modal" href="javascript:void(0);">here</a>

Put an element in your source page (here page.php as you wrote) and give it a unique id or anything else (for example id="CloseModal"). And in your script, write this event handler:
$('body').on('click', '#CloseModal', function () {
closePopup(fadeOutTime);
});
If you don't want to change your source page, and make close button globally for all popups, change your modalPopup function and add these lines to it:
var closeDiv = document.createElement('div');
closeDiv.setAttribute('id', 'CloseModal');
closeDiv.innerHTML = '[CLOSE]';
popupDiv.appendChild(closeDiv);
These code will add the close tag to the popup itself. And jquery code that I wrote before, will handle the click of it.
Here is your final scripts and functions:
<script language="javascript">
$(document).ready(function() {
//Change these values to style your modal popup
var align = 'center'; //Valid values; left, right, center
var top = 100; //Use an integer (in pixels)

var borderColor = '#333333'; //Use any hex code
var borderWeight = 4; //Use an integer (in pixels)
var borderRadius = 5; //Use an integer (in pixels)
var fadeOutTime = 300; //Use any integer, 0 = no fade
var disableColor = '#666666'; //Use any hex code

If you are using boostrap then use this code onclick of close button or image
$("#your-popup-id").modal('hide');
and if you are not using boostrap then this will work
$("#your-popup-id").hide();

Javascript doesn't work in only firefox

I have a script that hover over a thumbnail and it will show an enlarged image. This work just fine in IE, Chrome, and Safari. But in Firefox however it is not working correctly. It will show the image, but it will not hover next to the image correctly. It will stay in an absolute location on the page and not follow the true body value. It should be in a fixed location like it is in IE or chrome.
I was wondering if there is a Mozilla or Firefox specific exception I need to add. Here is my code:
// Simple Image Trail script- By JavaScriptKit.com

Your truebody function is running different code in different
browsers. Have you tried not doing that? – Boris Zbarsky 15 hours ago
I have been trying to figure out what to write there. I just don't know what to put for just firefox/mozilla. That is the only browser having the problem.
I see that the truebody isn't being read in Firefox, I just don't know why or how to fix it.

I've probably broken the script just TRYING to clean up this unholy mess and simplifying things a little, but at least it seems to be a bit more readable now (not including the array definitions):
<script type="text/javascript">
var dragging;
function mouseDown(el) {
dragging = el.id;
el.style.position = "fixed";
el.style.zIndex = 1000;
el.style.left = event.clientX - 75;
el.style.top = event.clientY-15;
}
function mouseOut(el) {
if (dragging === el.id) {
el.style.left = event.clientX - 75;
el.style.top = event.clientY - 15;
}
}
function mouseMove(el) {
if (dragging === el.id) {
el.style.left = event.clientX - 75;
el.style.top = event.clientY - 15;
}
}
function mouseUp(el, i) {
dragging = false;
if ( (event.clientX < 450) ||
(event.clientY > (180 + (abilitytypes[i] * 90)) ) ||
(event.clientY < (100 + (abilitytypes[i] - 1) * (90 * abilitytypes[i]) / ((4 % abilitytypes[i]) + 1)))) {
el.style.position = "relative";
el.style.top = 0;
el.style.left = 0;
el.style.zIndex = 0;
} else {
el.style.left = 460;
el.style.top = (Math.round((event.clientY - 30) / 45) * 45) + 15;
if ((abilitys[Math.round((event.clientY - 120) / 45)] != "") && (abilitys[Math.round((event.clientY - 120) / 45)] != el.id)) {
var subel = document.getElementById(abilitys[Math.round((event.clientY-120)/45)]);
subel.style.position="relative";
subel.style.left=0;
subel.style.top=0;
}
abilitys[Math.round((event.clientY - 120) / 45)] = el.id;
alert(abilitys);
}
}
for(var i = 0; i < 64; i++){
document.write("
<div onmousedown='mouseDown(this);'
onmouseout='mouseOut(this);'
onmousemove='mouseMove(el);'
onmouseup='mouseUp(this, i);'
id='"+i+"'
class='abilityblock"+abilitytypes[i]+"'>
<div class='abilityicon' style='background-position:"+(Math.floor(i/8)*-20)+"px "+((i%8)*-20)+"px;'></div>
<div class='abilityname' style='color:"+abilitycolors[Math.floor(i/8)]+";'>"+abilitynames[i]+"</div>
</div>");
}
</script>
Phew. And after all that, I'm guessing your missing 'left' and 'top' parameters are because your dynamically computed element IDs are generating non-existent IDs in the mouseup handler.
My suggestion? Scrap this home-brew drag 'n drop stuff and use the functionality provided by Mootools or jQuery. Far less trouble, especially when having to deal with cross-browser differences.

Searching your code, you haven't defined an onmouseover event. You define onmousedown, onmouseout, onmousemove, and onmouseup. No onmouseover.
