So for a school assignment I need to make a javascript module/small lib. so I'm making something that wil skew panels on mouse out. But something keeps going wrong. This is the code I've got;
var panels = (function () {
var ANGLE = 45;
var skewPanels = document.querySelectorAll(".skewPanel");
var colors = ['#4975FB', '#924DE6', '#EF5252', '#F59500'];
for (var i = 0; i < skewPanels; i++) {
floatable(skewPanels[i], colors[i]);
}
function floatable (panel, color) {
let content = panel.querySelector(".content");
content.style.backgroundColor = color;
panel.addEventListener('mouseout', e => {
content.style.transform = `perspective(300px)
rotateY(0deg)
rotateX(0deg)`;
});
panel.addEventListener('mouseout', e => {
var w = panel.clientWidth;
var h = panel.clientHeight;
var y = (e.offsetX - w * 0.5) / w * ANGLE;
var x = (1 - (e.offsetY - h * 0.5)) / h * ANGLE;
content.style.transform = `perspective(300px)
rotateX(${x}deg)
rotateY(${y}deg)`;
});
}
return {
floatable: floatable
}
})();
This is the html code.
<div class="skewPanel">
<div class="content">HOVER</div>
</div>
<div class="skewPanel">
<div class="content">HOVER</div>
</div>
<div class="skewPanel">
<div class="content">HOVER</div>
</div>
<div class="skewPanel">
<div class="content">HOVER</div>
</div>
<script type="text/javascript">
panels.floatable();
</script>
So I keep getting the error "Cannot read property 'querySelector' of undefined". I don't understand why this error comes up, I am giving it the div to find look for ".content". I got it working in non-modular style, but now it keeps breaking on me. Could someone explain to me what I'm doing wrong?

I'm trying to get a nice knob/dial that can be rotated to send a value back to the server via websockets.
The basic premise works well, I got the code from the web.
I am trying to modify the code so that I get a prettier knob. I've been successful by placing the canvas inside a couple of divs which display static images, while the canvas rotates a translucent image in response to mouse/touch events.
The additions that I made to the code work well on the desktop (I'm running Firefox 45.0.2) but do not work at all on an iPad (Safari, iOS 9.3.5) and only partially on an iPhone (iOS 10.2.1)
On the iPhone, the knob rotates in the opposite direction to that expected, and often only horizontal movement will start the knob rotating.
I'm not using (nor do I want to use) any libraries such as jquery.
The code below will work as is. However, removing the comment marks in the body section will cause the problems I indicated.
(Oh and to forestall any comments, the black background and odd text colour is just there to so that you can see the translucent element without the static backgrounds)
I'm not at all experienced with jscript and can only just manage to follow what the code is doing at the moment. (one of the reasons I don't want to use additional libraries)
I suspect that the problem lies with how the touch event coordinates are interpreted, but I can't test them in any way.
Any help or suggestions would be appreciated.

I might need to add an additional comment to give the link to the backgound image
knob_bg.png

So, after managing to find out how to debug html on an ios device via firefox on windows, I have managed to find out what was causing my code to fail.
The problem was in the function check_update_xyra(event, mouse_xyra)
Specifically the lines :
x = (touches[0].pageX - touches[0].target.offsetLeft) - PIVOT_X;
y = PIVOT_Y - (touches[0].pageY - touches[0].target.offsetTop);
The target.offsetxxx was returning a value of 0. This made the radian value (r) to be out of bounds which caused the function to return false, or in the case of the iPhone caused the touch event to behave strangely.
The reason for for the offsets coming back as 0 was because I did not factor in the fact that they provided the offset from the targets parent only, not the document as a whole.
I managed to fix this by adding some code to add the offsets for all parent elements then used that sum to calculate new x and y coordinates.
My code change follows.
However, if anyone has a more elegant method of calculating the offsets, I would appreciate it.
Cheers...
function check_update_xyra(event, mouse_xyra) {
var x, y, r, a;
var tgtoffleft = 0;
var tgtofftop = 0;
var min_r, max_r, width;
if(event.touches) {
var touches = event.touches;
// Bit of code to calculate the actual Left and Top offsets by adding offsets
// of each parent back through the hierarchy
var tgt = event.touches[0].target;
while (tgt) {
tgtoffleft = tgtoffleft + tgt.offsetLeft;
tgtofftop = tgtofftop + tgt.offsetTop;
tgt = tgt.offsetParent;
}
// x = (touches[0].pageX - touches[0].target.offsetLeft) - PIVOT_X;
// y = PIVOT_Y - (touches[0].pageY - touches[0].target.offsetTop);

Hello I have been trying to figure something out for a couple days, I'm hoping someone may be able to shed some light on the situation.
I've been trying to code out a learning project. The goal is basically a gantt chart where I'd like to plot some events on eventually.
I am drawing out the timeline on a canvas, right now I have the "Seconds" lines being drawn 50px apart, with 4 shorter lines between them representing 200ms spaces.enter code here
var aTime = "00:1:00.0";
var h, m, s, ms, totalSeconds, thecanvas = null;
// within the loop at line 76 I'm trying ( i * secondsSpacing ) to get the X
//position to draw the lines for each second.
//Why would this not drawing the lines 50 pixels apart?
var secondsSpaceing = 50;
var spaceTime = 44;
var mousePositioning = { x:0, y:0};
var zoom1a = 1;
function drawStroke(sX, sY, eX, eY, color) {
thecontext.strokeStyle=color;
thecontext.lineWidth=1;
thecontext.beginPath();
thecontext.moveTo(sX,sY);
thecontext.lineTo(eX,eY);
thecontext.stroke();
}
function secToMinSec(seconds) {
var min = Math.floor(seconds / 60);
var sec = Math.ceil(seconds % 60);
sec = (sec < 10) ? "0" + sec : sec;
return new Array(min, sec);
}
var mouseXY = function(eve) {
if(!eve) var eve = window.event;
var totalOffsetX = 0;
var totalOffsetY = 0;
var canvasX = 0;
var canvasY = 0;
var canvas = this;
do{
totalOffsetX += canvas.offsetLeft;
totalOffsetY += canvas.offsetTop;
}
while(canvas = canvas.offsetParent)
canvasX = eve.pageX - totalOffsetX;
canvasY = eve.pageY - totalOffsetY;
return {'x':canvasX, 'y':canvasY}
}

mousePositioning = thecanvas.xy(e);
$("#output").html( "X = " + mousePositioning.x +
"<br> Y = " + mousePositioning.y );
});

var splitTimeStr = splitTimeStrMS[0].split(':');
h = parseInt(splitTimeStr[0]);
m = parseInt(splitTimeStr[1]);
s = parseInt(splitTimeStr[2]);
ms = parseFloat(splitTimeStrMS[1]);
var X = 60;
totalSeconds = (h * X * X) + (m * X) + s;
var divided = Math.ceil(totalSeconds / zoom1a);
var timeChartArray = new Array();
for(var i = 0; i <= divided; i++) {
timeChartArray.push(i * zoom1a);
}
var neededCanvasWidth = Math.ceil(timeChartArray.length * secondsSpaceing);

//draw the line
var xline = parseFloat(i * secondsSpaceing);
drawStroke(xline, 0, xline, 8, lineColor);
//draw the time text
var timeStr = secToMinSec( timeChartArray[i] );
var timeFormatted = timeStr[0] + ":" + timeStr[1];
var timeXpos = (xline - 10);

If you move the mouse over the one second mark, you will see it is at x:50, two second mark is x:100 but then the three second mark is x:149, the same pattern continues and I keep losing seconds. By the fifth second, it should be at x:250 but its lost two seconds and is x:248. I'm still trying to figure this out myself but hopeful someone can shed some light as it's becoming discouraging. Thanks for reading.
EDIT: the code snippet worked in the editor, but I noticed when I press the "Run snippet" button that it's not showing the mouse position as it did in the editor, and on jsFiddle.
Here is a link to the project on jsFiddle:
https://jsfiddle.net/4y0q2pdw/19/
Thanks again
Check this.I saw that every 1 sec the function subtracted 4px. So I replace the
var xline = parseFloat(i * secondsSpaceing);
with the
var xline =parseFloat((i * secondsSpaceing)+3.6*i);
Initially I set instead of 3.6 the integer 4 but the function added then 1 or 2px after the 8 seconds line.So to be more accurate I replace the 4 by 3.6 that is more accurate.
I am trying to get the processing code from textbox and make it running in canvas but i don't know what is happening can someone help me? When i debug it's says ctx.compile(); is not a function how can i make it work propperly? Here is the code i use.

The error "ctx.compile(); is not a function" is expected since you are trying to call a function that does not exist on the 2d canvas context. If I understand correctly, you are trying to run your own compile function and render it on the canvas you just created.
To do so, you need to change a few things, try the following and see if it works:
function canvas() {
var ifrr = document.getElementById('iframeResult');
var iframediv = (ifrr.contentWindow.document) ? ifrr.contentWindow.document : (ifrr.contentDocument.document) ? ifrr.contentDocument.document : ifrr.contentDocument;
var canv = document.createElement('canvas');
canv.setAttribute('id', 'mycanvas');
// The ctx will be created in an instance of Processing.
// So no need for the following line.
// var ctx = canv.getContext("2d");
compile(canv);
iframediv.body.appendChild(canv);
}
// Here you can pass the canvas where you want to render the code.
function compile(canv) {
var processingCode = document.getElementById('textCode').value;
var jsCode = Processing.compile(processingCode).sourceCode;
// Now that you have the code in JS, you can create an instance of Processing.
// But, what you get from the compiler is a string,
// so you need to convert the string to JS.
// For instance, I use here eval(jsCode)
var processingInstance = new Processing(canv, eval(jsCode));
}
i found a script that would position divs / images randomly. However, it isn't completely working the way i want/need it to.
The images are loaded each within a div (which isn't ideal i guess). I have around 30 images.
But they don't load nicely and var posy = (Math.random() * ($(document).height() - 0)).toFixed(); doesn't work nicely either. The images mostly load on top (i think that the images in the blog don't count so it gets the height without images?)
So what I want: Load the in more nicely Randomize them so they get to the bottom of the page, too
var circlePosition = document.getElementsByClassName('circle');
console.log(circlePosition);
function position() {
for (var i = 0; i < circlePosition.length; i++ ) {
//give circle a random position
var posx = (Math.random() * ($(document).width() - 0)).toFixed();
var posy = (Math.random() * ($(document).height() - 0)).toFixed();
//apply position to circle
$(circlePosition[i]).css({
'position':'absolute',
'left':posx+'px',
'top':posy+'px',
})
}
} //end function position
var circleTotal = circlePosition.length;
$('.circle').click(function() {
$(this).fadeOut();
circleTotal = circleTotal - 1;
console.log(circleTotal);
if(circleTotal == 0) {
position()
$('.circle').fadeIn();
}
});
position();

A clean and readable and solution without a jQuery dependence might be something like this. It avoids unnecessarily wrapping your images in divs by positioning the images themselves. It includes a hidden element as a sort of "poor man's" shadow DOM.

try moving your position(); call inside the $(window).load function.
I think maybe the images are being positioned before all the images have loaded, so the page is shorter then.
I am populating a carousel menu dynamically. For this i have a web-method which returns the inner html of carousel div in string format.
On page load i have called a java-script from server side. this javascript called the web method and on success load the inner html of div.
Problem is that, it is working when i refresh the page. not in first load. Also it is not working on IE. Yet it is working on my local ISS (only in Chrome).
Below is the java-script
<script type="text/javascript" >
function HandleIT() {
var a = document.getElementById("carousel");
PageMethods.GetCarousel(onSucess, onError);
debugger;
function onSucess(result) {
debugger;
document.getElementById("carousel").innerHTML = result;
}
function onError(result) {
alert('Something wrong.');
}
}
</script>
this is how i have called this javascript from server side on page load.
ClientScript.RegisterStartupScript([GetType](), ClientID, " HandleIT();", True)
below is the carousel JS

count++

Also i am using the moottools JS
Can any one please help. I have checked it in IE. it is not showing any error of Javascript. But it not loads. It only shows a big icon of first item (in both chrome and IE). And after reload it works in chrome not in IE.
