I'm learning jQuery and I built my project using xdk, but square is not moving(when button is clicked). I checked it on android 4.4. and nothing(it's working on my pc). Can you help me?
This is my code:

$(document).ready(function () {

var right = $("#prawy");
var cube = $("#cube");

var krok = "10px";
left.click(function () {
cube.animate({

}, "fast");
intel.xdk.notification.vibrate();
});
right.click(function () {
cube.animate({
left: "+=" + krok
}, "fast");
intel.xdk.notification.vibrate();
});
down.click(function () {
cube.animate({
top: "+=" + krok

intel.xdk.notification.vibrate();
});
up.click(function () {
cube.animate({
top: "-=" + krok
}, "fast");
intel.xdk.notification.vibrate();
});
});
Edit: i tried other build options (crosswalk/cordova) but still nothing
yes, It can be happen, some times,because mobile is the different platform and web is different
if your app works in emulator but not in device, then The api is blocked due to Cross domain access, which is the same reason why your code will not work in any browser. But there is a way to make it work in Intel XDK apps, just add after your intelxdk.js script inclusion. It will then work on device.
More info about AJAX and XDK here: http://software.intel.com/en-us/html5/articles/how-to-access-JSON-data-in-HTML5-apps
Try including <script src="xhr.js"></script> after the <script src="indelxdk.js"></script> inclusion.

I've been trying to do a somewhat of a converter but i dont know how to submit variables through button and process them.
I tried 'attaching' to , after which is pressed, the code outputs an equivalent of meters in floors of a building for demonstration, but the log says that "calculus() is not defined", though it is cleadly in the and named accordingly. What am i doing wrong?
There are some errors on your code.
Firstly, your script is inside the style tag, but it shoud be outside.
Secondly, to define the function calculus you should use the function keyword function calculus() {}.
Thirdly, if you want to write the text into the output element, yous can not use the console.log function.
Finally, you should use getElementById instead of getAttributeById to fetch the element and then get the value.
The final code should be the next one:
<!DOCTYPE html>

<link rel="stylesheet" type="text/css" href="mystyles.css" media="screen" />
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

}
#output {

font: small-caps bold 24px/1 sans-serif;
bottom: 50vh;
}
</style>
<script>
function calculus() {
floor_height = 0
height_input_code = document.getElementById("height_input").value
floor_height = height_input_code / 2.7
document.getElementById("output").textContent = 'This height is approximately ' + floor_height + ' floors of a regular living building'
}
</script>
</head>
<body>
<div id="input">
<input type="number" step="any" id="height_input" style="margin:0; width: 1000px; height: 50px; font-size:2vw; border: solid 2px black">

</div>
<div id="output">
</div>
</body>
</html>
Make your style and your script tags separate
<link rel="stylesheet" type="text/css" href="mystyles.css" media="screen" />
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<style>
body {
margin: 0;
background: #595959;
height: 100%;
overflow-y: hidden;
overflow-x: hidden;
}
#input {
position: absolute;
margin-top: 50vh;
margin-left: 3vw;
bottom: 70%;
}
#output {
position: absolute;
font: small-caps bold 24px/1 sans-serif;
bottom: 50vh;
}
</style>
<script>
calculus() {
floor_height = 0
height_input_code = document.getAttributeById("height_input").value
floor_height = height_input_code / 2.7
console.log('This height is approximately', floor_height, 'floors of a regular living building', target='output')
}
</script>
2 function compute needs to be defined as
function compute(e) {
3 You can't use console.log to send your log to an html element. Here's how to do it
document.getElementById("output").textContent = floor_height;
What I'm trying to do here is dynamically add and display content as HTML inside an iframe by using jquery to set the srcdoc attribute on the click of a button. Nothing happens though when I click on the button:
Strangely enough, when I replace $("#myFrame").srcdoc with document.getElementById("myFrame) the code works as intended. That further baffles me.

I cannot make a simple click event on the "canvas" using JQuery click function.
$(document).ready(function(){
alert("test");
$("#canvas").click(function(){
alert("canvas");
});
$(".middle").click(function(){
alert("middle");
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="middle">middle
<div id="canvas">canvas</div>
</div>
"test" message is appearing but functions above is not working. Other siblings of div "middle" (I did not include since I tried to remove them for testing and it still happening) can execute events but only this div and inside cannot execute a single event.
Tried also to console.log($("#canvas")) and it fetches some data below.
[div#canvas]
here is the complete html:

Below is the image of the divs:
This is really frustrating because this is a basic function that I cannot call.
Edit:
I added a https://jsfiddle.net/5mtt2khu/
Please let me know any questions.
Thanks!
Do with event.target element .And match with condition
Updated js Fiddle
$(document).ready(function() {
alert("test");
$(".middle").click(function(e) {
if($(e.target).attr('id')== 'canvas'){
alert('canvas')
//do stuff for canvas
}
else{
alert("middle");
//do stuff for middle
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="middle">middle
<div id="canvas">canvas</div>

Updated
Remove or change the z-index
$(document).ready(function() {
alert("test");
$(".middle").click(function(e) {
if ($(e.target).attr('id') == 'canvas') {
alert('canvas')
//do stuff for canvas
} else {
alert("middle");

Your code seems to work.
So the problem must come from other things. Here is some possibilities :
JQuery is not correctly installed
You have a javascript error before so this is never executed
Your html is dynamically added after you load the event handler
You have an other div with the same id somewhere
If your html is dynamically added, I recommend you to do something like this
$(document).ready ( function () {
$(document).on ("click", "#canvas", function () {
alert("canvas");
});
$(document).on ("click", "#middle", function () {
alert("middle");
});
});
If you have several "canvas" id, you can do something like :
$("[id=canvas]").click(function () {
alert("canvas");
});
I think you are looking for something like this:
$(document).ready(function(){
alert("test");
$("#canvas").click(function(e){
alert("canvas");
e.stopPropagation();
});
$(".middle").click(function(){
alert("middle");
});
});
.middle {
width: 200px;
height: 200px;
background: red;
}
#canvas {
width: 100px;
height: 100px;
background: green;
margin: 50px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="middle">
<div id="canvas"></div>
</div>
Hope it helps :)

});
</script>
Try to change the div to input type or button.It works when I specified the color to the div and clicking it.So, without knowing where to click the event was not working.
Your jQuery code is actually working fine as it should. The problem here is propably because the canvas has no height and width defined, so it's too small to actually be able to click on it.
Give the divs a height and width like the below code snippet and you'll see that the jQuery gets executed correctly.
$(document).ready(function(){
alert("test");
$("#canvas").click(function(){
alert("canvas");
});
$(".middle").click(function(){
alert("middle");
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="middle" style="border: 1px solid black; height: 50px; width: 100px;">
<div id="canvas" style="border: 1px solid red; height: 15px; width: 30px;"></div>
</div>
Here is my problem:
I have image in one div that is centered into that div.
I want that that image go in header after user scroll once (scroll>50).
Here is my codepen example.
HTML:
<header> <div id="nav"> LINK LINK LINK </div> </header>
<div id="main">
<img src="https://img.clipartfest.com/3c73a51504b9b1ee6d200d1e60725b79_triangle-quilatral-triangle-shape-clipart-no-background_2400-2080.png">
</div>
CSS:
*{
padding:0;
margin:0;
overflow-x:hidden;
}
#nav{float:right; line-height:70px;}
header{
width:100%;
position:fixed;
padding-left:10%;
padding-right:10%;
background:#fff;
height:70px;
}
#main{
padding-top:100px;
text-align:center;
height:800px;
background:#3cb5f9;}
#main img{width:200px; margin:0 auto;}
There are a ton of ways to do this, but a quick way to achieve this is to duplicated the image so there is a copy of it in the main and the header. On load, have it hidden within the nav. Then, have a scroll event listener that watches for an offset of >50.
If true, => hide main image, and show nav image
If false => show main image. and hide nav image.
Also worth noting I updated the height of main to be 200vh — just to simulate content. This is not related to the answer.
$(function(){
$(window).bind('scroll', function(){
if($(window).scrollTop() >= 50){
$("#main img").hide();
$("header img").show();
}else{
$("#main img").show();
$("header img").hide();
}
});
});
* {
padding: 0;
margin: 0;
overflow-x: hidden;
}
#nav {
float: right;
line-height: 70px;
}
header {
width: 100%;
position: fixed;
padding-left: 10%;
padding-right: 10%;
background: #fff;
height: 70px;
}
header img {
display: none;
width: 50px;
margin: 0 auto;
}
#main {
padding-top: 100px;
text-align: center;
height: 200vh;
background: #3cb5f9;
}
#main img {
width: 200px;
margin: 0 auto;
}

Ok, I am creating a landing page, where what I want to happen, is the page split in half, and either side slide off of the screen, and the main page is left. I almost have it, but what the right side is doing, is whenever the window is at certain sizes, it is going below the left side. I'm not sure quite how to fix this, and everything I try doesn't really work, and there I haven't been able to find any answers online. Thanks for any help
