I am Working on a project in which I am trying to display a clock inside container so that the clock becomes responsive. I was hoping if someone can guide me on how to go about it.
Below is the HTML page where I am trying to display the same.
<!DOCTYPE html>
<html lang="en">
<head>

Something like this should work for you.
<!DOCTYPE html>
<html>
<head>
<script>
function startTime() {
var today = new Date();
var h = today.getHours();
var m = today.getMinutes();
var s = today.getSeconds();
m = checkTime(m);
s = checkTime(s);
document.getElementById('txt').innerHTML =
h + ":" + m + ":" + s;
var t = setTimeout(startTime, 500);
}
function checkTime(i) {
if (i < 10) {i = "0" + i}; // add zero in front of numbers < 10
return i;
}
</script>
</head>
<body onload="startTime()">
<div id="txt"></div>
</body>
</html>
Note: You don't need to insert a script or something for this purpose.
You could build a clock using the jquery you imported
make sure you put the script after your jquery script tags
<script type="text/javascript">
$(document).ready(function(){
var timer = setInterval(clock, 1)
function clock(){
$(".demo").html(Date());
}
});
</script>
<body>
<p class="demo"></p>
</body>

I'm totally lost as to where to begin here, how would I create a countdown button so that each time my button is clicked, it prints out the global variable and reduce it by 1 in the innerHTML and when it hits 0 it says BOOM?
I know I have to declare the variable outside but not sure what to do afterwards
JS:
var i = 20
function myFunction()
{
i = i--; // the value of i starting at 20
}
HTML:
<!DOCTYPE html>
<html lang="en">
<head>
<!-- link to external JS file. Note that <script> has an
end </script> tag -->
<meta charset="utf-8">
<title> Task 6 </title>
<link href="style.css" type="text/css" rel="stylesheet">
<script src="task6.js" type="text/javascript"></script>
</head>
<body>
<!-- Create a paragraph with id mydata -->
<div id="box">
<p id="mydata"> Count Down </p>
<p> <button onclick="myFunction();"> Click </button></p>
</div>
</body>
</html>
I tryed this code and works fine
var i = 20;
function myFunction() {
myData = document.getElementById("mydata");
i = i - 1;
myData.textContent = i;
if(i <= 0) {//with <=0 the user if click again,after zero he sees only BOOM
myData.textContent = "BOOM!"
}
}

It's good practice to not inline JS in the HTML so I'll provide an extra example to show how to separate it out using a couple of DOM selection methods:
let count = 20;
// grab the element with the mydata id
const mydata = document.getElementById('mydata');
// grab the button and attach an click event listener to it -
// when the button is clicked the `handleClick` function is called
const button = document.querySelector('button');
button.addEventListener('click', handleClick, false);
function handleClick() {
if (count === 0) {
mydata.textContent = 'Boom';
} else {
mydata.textContent = count;
}
count--;
}
<body>
<p id="mydata">Countdown</p>
<button>Click</button>
<script src="task6.js" type="text/javascript"></script>
</body>
Reference
getElementById
querySelector
addEventListener
I'll assume you want to show the variable output and the BOOM at the <p id="mydata"> Count Down </p>, if I am mistaken correct me. So, something like this:
let i = 20;
const myData = document.querySelector("#mydata");
function myFunction() {
i = i - 1;
myData.textContent = i;
if(i === 0) {
myData.textContent = "BOOM!"
}
}
You almost got it whole,only missed the textContent and if part. If this is what you wanted to achieve. If this isn't what you were looking for, hit me up so I can correct it. Cheers :)
You need some way of displaying the number inside of your variable. One of the simplist ways to do this would be to set text to your paragraph tag using getElementById() and inner HTML. For example, after running your deincrement, on the next line you would do something like...
function myFunction()
{
i = i--; // the value of i starting at 20
document.getElementById("mydata").innerHTML = i;
}
This code simply grabs your "mydata" paragraph from the DOM and injects the number into the tag as html.
I want to know how you would go about getting a value from a color picker and returning it to a js script
Here is the HTML Code
<!DOCTYPE html>
<script type="text/javascript" src="Scripts/jquery-3.1.1.js"></script>
<script type="text/javascript" src="js/bootstrap-colorpicker.js"></script>
<link rel='stylesheet' href='css/bootstrap-colorpicker.css' />
<script type="text/javascript" src="js/bootstrap-colorpicker.min.js"></script>
<link rel='stylesheet' href='css/bootstrap-colorpicker.min.css' />
<html lang="en" xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta charset="utf-8" />
</head>
<body>
<p> test test test</p>
<div id="cp2" class="input-group colorpicker-component">
<input type="text" value="#00AABB" class="form-control" />
<span class="input-group-addon"><i></i></span>
</div>
<script>
$(function () {
$('#cp2').colorpicker({
color: '#AA3399',
format: 'rgb'
})
});
</script>
</body>
</html>
<script>document.getElementById("cp2").value = function () {
return rgb;
}
</script>
`
I am looking to return the value of the color picker which is in RGB format to a js script so that I will to able to assign vars like this
var 1 = rgb[1]
var 2 = rgb[2]
var 3 = rgb[3]
`
If you decide to help me I will be thankful and you could please explain so I can learn from it.
Check javascript function:
<script>
(function() {
var rgb = document.getElementById("cp2").value ;
return rgb;
})();
</script>
Hello i'm building an application where i want to dynamically change the source of an image in order to force reload it . The problem is that in order of this i only get a broken image on the browser. Instead , if a run the function manually by a button it runs perfect .

cameraApp.js
var cameraApp = angular.module('cameraApp',[]);
cameraApp.controller('HomeController', function($scope,$http,$timeout) {
function updateImage() {
var img = 'snapshots/camera.jpg'+ '?decache=' + Math.random();
console.log('Snapshot Loaded');
$scope.snapshot = img;
};
$scope.readSnapshot = updateImage;
$scope.getSnapshot = function() {
$http.get('/api/getSnapshot')
.then(function(response) {
// this callback will be called asynchronously
// when the response is available
console.log('Snapshot captured');
$scope.readSnapshot();
}, function(response) {
console.log('Error in capturing...');
});
}
$scope.intervalFunction = function() {
$timeout(function() {
$scope.getSnapshot();
$scope.intervalFunction();
}, 2000);
};
// Kick off the interval
$scope.intervalFunction();
});
There are two solutions I've used for this in the past.
1) Use an ng-if/ng-show on your img tag. This will prevent the broken image from displaying.
<img ng-if='snapshot'>
2) Set a default image that will load and then be replaced once the other images load.
$scope.snapshot = 'snapshots/default.png';
Here is my script.js:
var audio = new Audio('http://shrek.unideb.hu/~osnure/z/Gallows/Orchestra%20of%20Wolves/Gallows%20-%20In%20The%20Belly%20Of%20A%20Shark.mp3');
var timer, showCurrent=true;
$('#play').click(function(){
if (audio.paused){
audio.play();
$('#play').html('ll');
timer=setInterval(function(){update();},100);
}else{
audio.pause();
$('#play').html('►');
clearInterval(timer);
}
});
$('#speaker').click(function(){
if (audio.muted){
audio.muted=false;
}else{
audio.muted=true;
}
});
$('#total').click(function(e) {
var x = $(this).offset();
x=e.clientX - x.left;
x=x/210;
audio.currentTime=audio.duration*x;
update();
});
$('#time').click(function(e) {
if(showCurrent){
showCurrent=false;
}else{
showCurrent=true;
}
update();
});
function update(){
var d=0;
var ct=0;

var min=Math.floor(ct/60);

I've looked everywhere, and I can't find a resource that tells me how to insert the Javascript into the webpage. Any help would be greatly appreciated. I'm not much of a front-end developer.
Add the following at the end of your body tag:
<script src="pathToMy/javascriptFile/script.js"></script>
Unless your index.html and your script.js are in the same directory, your current script tag will not work.
Simply Do it Externally.And make sure u put it on end of the page for optimum performance.
I wanted to dynamically append a Table/List to HTML page. My code as follows:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width,initial-scale=1">
<title>Lead Manager</title>
<link rel="stylesheet" href="themes/Bootstrap.css">
<link rel="stylesheet" href="themes/jquery.mobile.structure-1.2.0.min.css" />
<script src="themes/jquery-1.8.2.min.js"></script>
<script src="themes/jquery.mobile-1.2.0.min.js"></script>
</head>
<body id="body" name="body">
<div data-role="page" data-theme="a">
<div data-role="header" data-position="inline">
<h1>Lead Manager</h1>
</div>
<div data-role="content" data-theme="a">
<h2>List of Leads</h2>
</div>
</div>
</body>
<script>
$(document).ready(function(e) {
//var data = Android.getLeads();
var data = [{"status":"1","name":"1","campaign":"1","date":"1"},{"status":"2","name":"2","campaign":"2","date":"2"}];
var items = [];
var date;
var name;
var status;
//eval(" var x = " + data + " ; ");
//var y = JSON.stringify(x);
$.each(data, function(key,val){
items.push('<tr><td>' + val.date + '</tr></td>');
});
var text = $('<table/>', { html: items.join('')});
$('<table/>', {
html: items.join('')
}).appendTo('body');
});
</script>
</html>
The Items[] variable is getting filled with the tr and td values. However, the appendTo, doesnt work. The JSON as you can see doesnt require eval as its already in the format required.
Please can you help?
The issue was mainly because of the jquery.mobile script as it wasnt allowing dynamic addition of html code.
