Update Distance Between Elements - javascript

I have two elements, and one is moving towards the other. I am trying to get the new distance as it moves closer. Consider the code below:
<html>
<center>
<body onload = 'start()'>
<div class='field'>
<div id='bull'></div>
<div id='mount'></div>
</div>
<button id='one'>DO</button>
</body>
</center>
<style>
.field{
width: 440px;
height: 260px;
background: rgba(0, 0, 0, .2);
margin-top: 30px;
border: 1px solid #222;
border-radius: 10px;
}
#bull{
width: 15px;
height: 10px;
background: #000;
border-top-right-radius: 5px;
border-bottom-right-radius: 5px;
position: absolute;
}
#mount{
width: 60px;
height: 30px;
background: rgba(20, 10, 45);
color: #fff;
border-radius: 4px;
margin-top: 210px;
}
</style>
<script type='text/javascript'>
function start() {
var ball = document.getElementById('bull');
var button = document.getElementById('one');
var mount = document.getElementById('mount');
button.addEventListener('click', go);
var x_pos = 0;
var y_pos = 0;
var bounce_point = 200;
var ball_dim = ball.getBoundingClientRect();
var ball_h_half = ball_dim.width / 2;
var ball_w_half = ball_dim.height / 2;
var mount_dim = mount.getBoundingClientRect();
var mount_h_half = mount_dim.width / 2;
var mount_w_half = mount_dim.height / 2;
function go() {
for(x_pos = 0; bounce_point > x_pos; x_pos++) {
ball.style.margin = x_pos + "px";
ball.style.transition = x_pos/2 + "s";
var dist = ((ball_h_half - mount_h_half)*(ball_w_half - mount_w_half)) + ((mount_h_half - ball_h_half)*(mount_w_half - ball_w_half));
console.log(dist);
if(dist < 3) {
console.log('One');
}
}
}
}
</script>
When bull reaches comes within 3px of mount, nothing happens... I've pretty much explained the issue as best as I can.

Well i tried a little bit more, and your logic doens't seem to fit to what you want to do. First of all, you probably noticed your value in the log doesn't change.
It could have been because the values are retreived outside the loop, but not only (they actually have to be in the loop to be updated). You have 2 other problems: first, you are measuring the elements width and height, which don't take account of margin or other positioning. Your elements don't change size, so the value also won't. The other problem is actually the transition itself on the movement. Because of the delay, all your loop iterations are most probably done, and the margin already set to its final value when your "bull" effectively starts to move. It means that in the loop, you can't detect the position change, the element having not started to move yet. Using the value that was just set (margin) instead of detecting the real position of the element should show a progression for the value, but it makes harder to detect the collision because your 2 elements don't have the same positioning rules and you can't just compare the margins.
Here is a quick example that gets updated values (because the transition has been disabled, if you enable back, the problem comes again). You'll notice your calculation for the collision is wrong too. You can't just compare a distance between 2 corners for that, for a rectangle it's rather "has gone beyond left vertical edge AND has gone beyond top horizontal edge" (this of course takes only in account the top left corner, to be complete, it should also be added that it must not have reached the right or bottom edge yet).
Well, I can't propose you an all ready solution, but this addresses your code main issues:
<html>
<center>
<body onload = 'start()'>
<div class='field'>
<div id='bull'></div>
<div id='mount'></div>
</div>
<button id='one'>DO</button>
</body>
</center>
<style>
.field{
width: 440px;
height: 260px;
background: rgba(0, 0, 0, .2);
margin-top: 30px;
border: 1px solid #222;
border-radius: 10px;
}
#bull{
width: 15px;
height: 10px;
background: #000;
border-top-right-radius: 5px;
border-bottom-right-radius: 5px;
position: absolute;
}
#mount{
width: 60px;
height: 30px;
background: rgba(20, 10, 45);
color: #fff;
border-radius: 4px;
margin-top: 210px;
}
</style>
<script type='text/javascript'>
function start() {
var ball = document.getElementById('bull');
var button = document.getElementById('one');
var mount = document.getElementById('mount');
button.addEventListener('click', go);
var x_pos = 0;
var y_pos = 0;
var bounce_point = 200;
var ball_dim, ball_x, ball_y, mount_dim, mount_x, mount_y, diff_x, diff_y;
var stayInLoop = true;
//ball.style.transition = "0.4s"; //i don't know why you updated the transition time based on position, changed to a fixed value outside the loop because it's quicker for the example
function go() {
for(x_pos = 0; bounce_point > x_pos && stayInLoop; x_pos++) {
ball_dim = ball.getBoundingClientRect();
ball_y = ball_dim.top + 10; // +10 because we're considering the bottom edge of bull
ball_x = ball_dim.left + 15; // +15 because we're considering the right edge of bull
mount_dim = mount.getBoundingClientRect();
mount_y = mount_dim.top;
mount_x = mount_dim.left;
diff_x = mount_x - ball_x;
diff_y = mount_y - ball_y;
console.log(diff_x, diff_y);
ball.style.margin = x_pos + "px";
if(diff_x < 3 && diff_y < 3) {
console.log('One');
stayInLoop = false;
}
}
}
}
</script>
EDIT/SUGGESTION: i suggest looking at window.requestAnimationFrame() MDN doc here for a better control on animations

why does my custom-made "cursor" falls behind the moving div elements when i hover over them?

hello everyone hope you guys are having a great day!
so, i am building a simple game where I use a custom-made cursor as the aim for shooting div elements moving around the screen as the enemies and when i apply the "pointerdown" event i want the enemy to change its color. however, every time i hover over the enemy the cursor falls behind witch i don't understand why, and when i use the z-index property it will prevent the "pointerdown" event from firing. if some cool OG programmer can help me, it would mean a lot to me.
style
* {
margin: 0;
padding: 0;
cursor: none;
}
.aim {
position: absolute;
background: black;
width: 10px;
height: 10px;
border-radius: 50%;
transform: translate(-50%, -50%);
}
.enemy {
position: absolute;
border: 3px solid black;
background-color: blue;
width: 50px;
height: 50px;
}
javascript
const body = document.body;
const aim = document.createElement("div");
const enemy = document.createElement("div");
body.appendChild(aim);
body.appendChild(enemy);
aim.classList.add("aim");
enemy.classList.add("enemy");
let enemy_X_position = 0;
let enemy_Y_position = 0;
let enemy_X_distance = 1;
let enemy_Y_distance = 1;
function Flight()
{
enemy.style.left = enemy_X_position + "px";
enemy.style.top = enemy_Y_position + "px";
}
setInterval(function()
{
enemy_X_position += enemy_X_distance;
enemy_Y_position += enemy_Y_distance;
if ((enemy_X_position + enemy.offsetWidth) >= window.innerWidth || enemy_X_position <= 0)
enemy_X_distance = -enemy_X_distance;
if ((enemy_Y_position + enemy.offsetHeight) >= window.innerHeight || enemy_Y_position <= 0)
enemy_Y_distance = -enemy_Y_distance;
Flight();
},1000/60)
window.onmousemove = function()
{
aim.style.left = event.pageX + "px";
aim.style.top = event.pageY + "px";
}
enemy.onpointerdown = function()
{
event.target.style.background = "red";
}
enemy.onpointerup = function()
{
event.target.style.background = null;
}
Update
The event is not triggering because pointerdown was received by aim when it sits on top of enemy.
To solve this, add pointer-events: none on aim class to prevent it from being the target of a pointer event.
More about pointer-events
Hope this will help!
.aim {
position: absolute;
background: black;
width: 10px;
height: 10px;
border-radius: 50%;
transform: translate(-50%, -50%);
pointer-events: none;
}
Original
Perhaps an over simplified solution, but it seems that if you reverse the order of appendChild, the aim should be stacked over enemy without additional styling.
Example:
body.appendChild(enemy);
body.appendChild(aim);
Because both elements are child of body, Unless there is other styling that override this stacking, the later one should be on top.

CSS display changes after changing zoom

I am having a little bit of trouble with my CSS, as when I change the default zoom (Command + on Mac) of the browser it causes the below image.
When it is at 100% viewport on chrome, it is supposed to look like the below where it fits perfectly in the black box.
My html code is below. For the sake of simplicity, I have only included the container and the tag to show where I wrote it.
<body>
<div class="container">
<div class="container-bars"></div>
</div>
</body>
My CSS code is below:
body {
background-color: rgb(89, 87, 87);
margin-right: auto;
margin-left: auto;
.container {
background-color: rgb(37, 35, 35);
height: 80%;
position: absolute;
width: 60%;
left: 500px;
top: 150px;
}
.bars {
float: left;
border: 1px solid rgb(232, 10, 10);
background-color: rgb(218, 215, 215);
}
The .container is the black box in the background and the body is the grey background. Finally, .bars just represents the CSS for each bar. I am creating a visualizer so the when adding the bars, I am using javascript. The code for adding the bars is below.
const container = document.querySelector('.container');
function add_bars(input) {
const Div = document.createElement('div');
const containerWidth = container.clientWidth;
const containerHeight = container.clientHeight;
const barWidth = containerWidth / inputval - 2;
Div.className = 'bars';
//prettier-ignore
Div.style.height = `${((containerHeight / 100) * input) - 2}px`;
Div.style.width = `${barWidth}px`;
containerBars.append(Div);
}
The input in this case is how large the size of the array is which I am dividing in order to split the width of each bar equally. Any help would be appreciated as to why it exceeds the container when I change how "zoomed" in the browser is. Thanks!
function for_loop(array) {
resetArray();
for (let i = 0; i < array.length; i++) {
add_bars(array[i]);
}
}
When you use % or vh vw in css and change zoom the elements will change their sizes. Try a console.log(document.querySelector(".container")) after and before changing zoom and you will see a different value. In order to avoid that behavior you have to use fixed sizes in your elements. For example:
.container {
background-color: rgb(37, 35, 35);
position: absolute;
height: 600px; // pixels, not % or vh
width: 800px;// the same
left: 150px;
top: 150px;
}
Also, when you make zoom out the problem persist. In order to avoid that just add the next:
* {
box-sizing: border-box;
}
And there is no need to substract 2 px in add_bars function:
...
const barWidth = containerWidth / inputval;
...
Div.style.height = `${((containerHeight / 100) * input)}px`;
...

javascript chatbox / messenger script

I'm trying to write a facebook like chatbox, but i've encountered a small problem.
I'm using the following code (it's only test code, so it's not really clean):
css code:
#messenger {
position: fixed;
bottom: 0px;
right: 10px;
width: 200px;
height: 300px;
z-index: 4;
background-color: #ECECEC;
border: 1px solid #000;
}
#messenger.p {
text-align: right;
}
#contacts {
margin: 5px 5px 5px 5px;
}
#chatspace {
position: fixed;
bottom: 0px;
right: 240px;
height: 20px;
left: 20px;
background-color: #ECECEC;
border: 1px solid #000;
z-index: 4;
}
.chatbox {
position: absolute;
bottom: 0px;
width: 200px;
height: 200px;
z-index: 4;
background-color: #ECECEC;
border: 1px solid #000;
}
html/javascript code:
<script type="text/javascript">
var i = 0;
function oc_chatbox() {
if (i == 0) {
document.getElementById('contacts').style.visibility = 'hidden';
document.getElementById('messenger').style.height = '20px';
i = 1;
}
else {
document.getElementById('contacts').style.visibility = 'visible';
document.getElementById('messenger').style.height = '300px';
i = 0;
}
}
function new_chat(userid) {
var new_right;
new_right = document.getElementById('messenger').style.right;
//alert('old value: '+ new_right);
new_right += 20;
//alert('New value of right: '+ new_right);
document.getElementById('chatspace').innerHTML = '<div id="'+userid+'" class="chatbox" style="right: '+new_right+'px;"></div>';
//document.write('<div id="'+userid+'" class="chatbox" style="right: '+new_right+'px;"></div>');
}
</script>
<div id="chatspace"></div>
<div id="messenger">
<p>Collapse</p>
<div id="contacts">
<ul>
<li>contact A</li>
</ul>
</div>
</div>
the problem is, that when I try to add new chats to the chatbar, i can't seem the place them next to each other.
anyone who can help ?
EDIT:
so i changed to javascript code to:
var last = null;
function new_chat(userid) {
if(userid==null)
userid = "user666";
var new_right;
var margin = 10;
var messenger = window.last==null?document.getElementById('messenger'):window.last; //Take the messenger or the last added chat
new_right = document.body.clientWidth-messenger.offsetLeft; //Compute the window size
console.log(new_right); //Log the number
new_right += margin; //keep spaces between divs
var newChat = document.createElement("div"); //DOM create DIV
newChat.id = userid;
newChat.className = "chatbox shadow";
newChat.style.right = new_right+"px";
newChat.innerHTML = '<p>'+userid+'</p><p><textarea></textarea></p>';
window.last = newChat; //Remember whichever is last
document.body.appendChild(newChat);
}
and now it works, thanks !
You cannot get an element right offset using its style, unlest the style is set and valid. Instead you must get element.offsetLeft and size of window area and do this:
new_right = windowSize()[0]-messenger.offsetLeft;
Where window size is this function.
Here is my, working, version of your function:
var last = null;
function new_chat(userid) {
if(userid==null)
userid = "user666";
var new_right;
var margin = 20;
var messenger = window.last==null?document.getElementById('messenger'):window.last; //Take the messenger or the last added chat
new_right = windowSize()[0]-messenger.offsetLeft; //Compute the window size
console.log(new_right); //Log the number
new_right += margin; //keep spaces between divs
var newChat = document.createElement("div"); //DOM create DIV
newChat.id = userid;
newChat.className = "chatbox";
newChat.style.right = new_right+"px";
window.last = newChat; //Remember whichever is last
document.body.appendChild(newChat);
}
You may get errors if console is not defined in your brouwser. But in such case you should take a better browser. Normally, the if(console!=null) is put in code.
And here is the link.
You should try adding a float style.
.chatbox {
float: right;
}
Add that to your chatbox styles. You may need to mess around a bit to make sure the float doesn't mess with your other elements. You may need a better container for them.
If you want to get really fun, you can add .draggable() from jQuery, and you can have them snap to your chat bar. You can then change the order of your chats.

Modifying cursor property for select portion of an element

I have this HTML that renders a simple arrow sign pointing towards the right:
<!DOCTYPE html>
<html>
<head>
<style>
div { width: 0px; height: 0px; border-left: 20px solid black; border-top: 20px solid transparent; border-bottom: 20px solid transparent; border-right: 20px solid transparent; position: absolute; left: 35px; top: 53px; cursor: pointer; }
</style>
<body>
<div></div>
</body>
</html>
If you hover of it, the cursor turns to pointer. But because it is actually a square div, the cursor turns pointer even if you are just outside the arrow within the perimeter of the div.
So I wrote this Javascript addition such that the cursor turns pointer only when the mouse is hovering over that arrow. For this purpose, I figured the coordinates of the three vertices of the triangle from Firebug ((35,53),(55,73),(35,93) clockwise from top). Then I check whether the point in question lies inside the triangle formed by these 3 vertices. This I do by checking whether the point and the opposite vertex for each edge lies on the same side of that edge or not (if they do, the product of the values obtained by substituting the coordinates of that point for x and y in that equation will be positive).
<!DOCTYPE html>
<html>
<head>
<style>
div { width: 0px; height: 0px; border-left: 20px solid black; border-top: 20px solid transparent; border-bottom: 20px solid transparent; border-right: 20px solid transparent; position: absolute; left: 35px; top: 53px; }
.hoverclass { cursor: pointer; }
</style>
<script src="jquery.js">
</script>
<script>
$(document).ready(function(){
$("div").click(function(e) { alert(e.pageX + " " + e.pageY); });
function l1(x,y) { return y - x - 18; }
function l2(x,y) { return x+y-128; }
function l3(x,y) { return x-35; }
$("div").hover(function(e) {
var x = e.pageX;
var y = e.pageY;
if (l1(x,y)*l1(35,93) >= 0 && l1(x,y)*l1(35,93) >= 0 && l1(x,y)*l1(35,93) >= 0 ) {
$(this).addClass('hoverclass');
}
else { $(this).removeClass('hoverclass'); }
},
function() {
$(this).removeClass('hoverclass');
});
});
</script>
<body>
<div></div>
</body>
</html>
However, the results are not predictable. Sometimes the cursor turns pointer within the triangle only, sometimes outside as well (just as before), and sometimes not at all. I suspect that this is probably due to the hover function working overtime, that may be temporarily hanging the script. Is there any other way to achieve this?
This could be done using HTML5 canvas. Basic idea is to check for pixel color on mousemove on canvas element. This way, your element can be of any form as you wish. Of course, you should make some optimization of following code:
SEE WORKING DEMO
function findPos(obj) {
var curleft = 0, curtop = 0;
if (obj.offsetParent) {
do {
curleft += obj.offsetLeft;
curtop += obj.offsetTop;
} while (obj = obj.offsetParent);
return { x: curleft, y: curtop };
}
return undefined;
}
// set up triangle
var example = document.getElementById('example');
var context = example.getContext('2d');
context.fillStyle = '#000';
context.strokeStyle = '#f00';
context.lineWidth = 1;
context.beginPath();
// Start from the top-left point.
context.moveTo(10, 10); // give the (x,y) coordinates
context.lineTo(60, 60);
context.lineTo(10, 120);
context.lineTo(10, 10);
// Done! Now fill the shape, and draw the stroke.
// Note: your shape will not be visible until you call any of the two methods.
context.fill();
context.stroke();
context.closePath();
$('#example').mousemove(function(e) {
var pos = findPos(this);
var x = e.pageX - pos.x;
var y = e.pageY - pos.y;
var coord = "x=" + x + ", y=" + y;
var c = this.getContext('2d');
var p = c.getImageData(x, y, 1, 1).data;
if(p[3]!='0') $(this).css({cursor:'pointer'});
else $(this).css({cursor:'default'});
});
You'd better use CSS instead. With :before and :after pseudo classes you can do magic. Check out this Pure CSS GUI icons by Nicolas Gallagher.
If you use any CSS pre-processor, these icons can be wrapped up as a mixin, this way required properties can be assigned like this:
#icon > .close(16px, #fff, #E83921);
You can make any shape have cursor pointer with CSS only. The idea is to rotate wrapper container which has overflow: hidden (you can have several of them depending on the shape you need). In case of OP problem this code does a trick:
<div class="arrow"><i></i></div>
.arrow {
margin: 100px;
border_: 1px red solid;
width: 40px;
height: 40px;
overflow: hidden;
-webkit-transform: rotate(45deg);
transform: rotate(45deg);
}
.arrow i {
height: 65px;
width: 65px;
background-color: green;
content: '';
display: block;
cursor: pointer;
margin: -35px 0 0 11px;
-webkit-transform: rotate(45deg);
transform: rotate(45deg);
}
See this demo: http://cssdesk.com/PaB5n
True that this requires CSS transform support so it's not cross browser.

Make element move by using Javascript

I am trying to make a webpage where when you click a link, the link moves diagonally every 100 milliseconds.
So I have my Javascript, but right now when I click the link nothing happens
Also, does anyone know of a Javascript IDE I can use to make sure I have no errors in my code?
PS: Does anyone know why my elements dont stretch to fit the whole 200px by 200px of the div element? The links are only small when they should be the same width as their parent div element.
Edited with new advice, although still wont move.

Errors needed to fix
To fill the width of the div elements, the a elements need to be display: block; not their default display: inline;.
Knowing runtime errors is more important in my opinion, and IDEs don't catch DOM errors or anything more complex than syntax; use the error logging in your browser (Firefox's is called Error Console). That'll also catch in-development errors like syntax errors.
This is the most important point to stress: block.style.left and block.style.top are not just numbers with implicit pixel values in them. Setting it to a number without a unit suffix will do absolutely nothing. You need to add % or px or whatever unit when setting left and top.
When getting the current value, as in var x = ... and var y = ..., you need to Number() manually to get the numeric portion of the string.
Also, I believe you meant || block == null, not =, which would set block to null.
Tips
You can use moveBlock instead of "moveBlock();" as an argument to setTimeout. This avoids parsing the string into code, and avoids scope problems (though not in this example as moveBlock is global).
I know that you have an array of values, where both x and y move 10 each time. I assume you want to move at a 45 degree angle. If so, this won't work as you expect even after fixing all the errors as x is percentage and y is in pixels.
You should declare your x and y above like your other variables. It may work but its confusing.
in your setTimeout, use moveBlock, not "moveBlock()" - it will save the step of evaluating your string into code.
block.style.left will return a string that includes "px" - it won't be a number. You can do:
x = Number(x);
//or
x = parseInt(x, 10);
When you set the position, remember to add the "px":
block.style.left = xPos[index] + "px";
EDIT:
Ok, the key problem is 'style.left' is not reading because it was set with CSS and not the style object. I use my library to get the style which runs through a few scenarios and catches that automatically. So change these lines to (this may not be exactly correct but will get things moving):
x = parseInt( node.style.left, 10 ) || 0;
y = parseInt( node.style.top, 10 ) || 0;
Also, this is wrong (you never declared 'self', and you don't need it here anyway; JS is case sensitive, SetInterval is not capped; pass the function, not the function result):
clockStep = self.SetInterval( moveBlock(), timerInterval ); // <-- result of moveBlock
// change to:
clockStep = setInterval( moveBlock, timerInterval ); // <-- the function moveBlock
During dev, you should remove the if() statements that could have been blocking the code and just put a simple count--; in there. It's really hard to debug code when you have literally 20 things wrong. Write a line, test. Write a line, test.
You have HTML comments in the script and style blocks. This is from 1998. While they don't hurt anything intact, in the past I've accidentally edited my code and removed one of them, and this will throw everything out of whack - your IDE, the browser - because they won't know what's wrong and you won't get a good error message.
LANGUAGE="JavaScript" is no longer used and is a waste of bytes.
To help speed development add this line:
window.onloadfunction(){
onBlockClick('block1')
}
That will execute your code right away for testing and you don't have to click every time.
Finally, I highly recommend you use Firefox and Firebug. Developing without it is like trying to build a ship in a bottle with boxing gloves. Using console.log(block.style.left) would have shown you it was not set. The error messages would have told you SetInterval and moveBlock() was incorrect. You do need to remember to remove the console.logs before production though. or... (shameless plug)... use my JavaScript Console Fix library which will do that for you: http://clubajax.org/javascript-console-fix-v2-now-with-ios/
