It should be straight forward but I can not get a function to change the image on button click. Please can anyone spot what is wrong with the below code. Thanks in advance.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>BlankCordovaApp4</title>
<!-- BlankCordovaApp4 references -->
<link href="css/index.css" rel="stylesheet" />
</head>
<body>
<p>Greeting!</p>
<img id="demo" src="images/hello.jpg" width="180" height="123">
<button id="Btn" type="button" onclick="changeImage();">Click Me</button>
<!-- Cordova reference, this is added to your app when it's built. -->
<script src="cordova.js"></script>
<script src="scripts/platformOverrides.js"></script>
<script src="scripts/index.js"></script>
<script>
function changeImage() {
document.getelementbyid("demo").src = "images/bye.jpg";
};
</script>
</body>
</html>
It should be:
document.getElementById("demo").src = "images/bye.jpg";
Case matters in javascript: getelementbyid is not the same as getElementById.

There are two versions of code. The first version is there is a main page containing an iframe and dialog <div>. The iframe will load the dia.html into the parent <div id="popdiv"> and fire it as a dialog. The dialog itself will initiate a Datepicker with elem.datepicker();.
The second version is just the ideal version for what I want which is an iframe fire the parent main page dialog and have a Datepicker running. But this approach cannot load the dia.html page into the <div id="popdiv"> which is not as handy.
My question:
Why is that when I want to select the element$('#myInput', window.parent.document) in the dia.html, I need to add window.parent.document after selector?
I try to figure it out by checking the html code in development tools. But I had no idea why it is required. How does query Dialog work?
How to make the elem.datepicker(); inside the dia.html work inside the dialog if I want to use the .load('dia.html') approach? What was the reason it didn't work?

I'm on a tutorial to create a success check mark with an animation.
I already created all the elements such as the box for the alert etc but have trouble with an animation.
Here is the code example I'm following : Link
I tried to do it on my computer putting the HTML part and the JS together and the css in a style.css sheet but doesn't work :(
Here is the HTML document :
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<link rel="stylesheet" href="style.css" />
<title>Test</title>
<script>
$("button").click(function () {
$(".check-icon").hide();
setTimeout(function () {
$(".check-icon").show();
}, 10);
});
</script>
</head>
<body>
<div class="success-checkmark">
<div class="check-icon">
<span class="icon-line line-tip"></span>
<span class="icon-line line-long"></span>
<div class="icon-circle"></div>
<div class="icon-fix"></div>
</div>
</div>
<center>
<button id="restart">Restart Animation</button>
</center>
</body>
</html>
I didn't copy the css as it is the same as is the link and a long code..
It gives me a white screen and a lot of warnings on code inspection :
As I'm doing something wrong please ?
Thank you for your help,
Jerry
jQuery is missing from your code, try adding adding it in the <head> section.
EDIT: You are also using a wrong .css file. I think you copied the uncompiled SCSS from the tutorial. To fix this, go back to the CodePen example and on the top-right corner of the CSS section open the context menu and click "View Compiled CSS". Then copy the CSS into style.css
Here is a working solution:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>Test</title>
<link rel="stylesheet" href="style.css" />
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.0.0/jquery.min.js"></script>
<script>
$(() => {$("button").click(function () {
$(".check-icon").hide();
setTimeout(function () {
$(".check-icon").show();
}, 10);
});});
</script>
</head>
<body>
<div class="success-checkmark">
<div class="check-icon">
<span class="icon-line line-tip"></span>
<span class="icon-line line-long"></span>
<div class="icon-circle"></div>
<div class="icon-fix"></div>
</div>
</div>
<center>
<button id="restart">Restart Animation</button>
</center>
</body>
</html>
I've tried for several hours know to make this bit of jquery code work but I just can't find what I did wrong with it. The equivalent in normal javascript works just fine. What is the problem?
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8"/>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js">
alert("HI");
$(document).ready(function(e){
alert("Hi");
$("#button5").click(function(event)
{
alert("HI");
});
});
</script>
</head>
<body>
<link rel="stylesheet" type="text/css" href="ezcap.css">
<div class="container">
<div id="sidebar">
<div id="sbheader"></div>
<div id="button2"></div>
<div id="button3"></div>
<div id="button4"></div>
<div id="button5"></div>
</div>
<div id="header">lol</div>
<div id="footer">feg</div>
</div>
</body>
</html>
You can't put a script in a tag that has a src attribute. You need to call the jQuery library in one script tag and then put your actual script in another.
Try this:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script type="text/javascript">
alert("HI");
$(document).ready(function(e){
alert("Hi");
$("#button5").click(function(event)
{
alert("HI");
});
});
</script>
Problem is here
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js">
//js code
</script>
Here in your script tag you are giving a source and some code also, You should write separate script tags for both, see bellow
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js">
</script>
<script>
//js code
</script>
Try this:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8"/>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script>
alert("HI");
$(document).ready(function(e){
alert("Hi");
$("#button5").click(function(event)
{
alert("HI");
});
});
</script>
</head>
<body>
<link rel="stylesheet" type="text/css" href="ezcap.css">
<div class="container">
<div id="sidebar">
<div id="sbheader"></div>
<div id="button2"></div>
<div id="button3"></div>
<div id="button4"></div>
<div id="button5"></div>
</div>
<div id="header">lol</div>
<div id="footer">feg</div>
</div>
</body>
</html>
You are trying to call the jQuery library while also implementing your code snippet here:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js">
You should be first loading the jQuery library and then implementing your code snippet like this:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script>
alert("HI");
$(document).ready(function(e){
alert("Hi");
$("#button5").click(function(event){
alert("HI");
});
});
</script>
The reasoning behind this is because you cannot call the script attribute to load a library and then define some code in the same tag, you need to:
Load the script
Declare your code
Hope that helps!
The JS script reference line of code should end and actual JQuery code should be enclosed under separate script tags.

Your problem was including your code in that script tag for jQuery.
Change to this:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8"/>
<link rel="stylesheet" type="text/css" href="ezcap.css">

<div id="sidebar">
<div id="sbheader"></div>
<div id="button2"></div>
<div id="button3"></div>
<div id="button4"></div>
<div id="button5"></div>
</div>
<div id="header">lol</div>
<div id="footer">feg</div>
</div>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script>
alert("HI");
$(document).ready(function(e){
alert("Hi");
$("#button5").click(function(event)
{
alert("HI");
});
});
</script>
</body>
</html>
Not a problem but you do not need the type="text/javasript". See: Do you need text/javascript specified in your <script> tags?
And it is better to have your scripts at the bottom so that your content can load faster. See: If I keep JavaScript at bottom or keep JavaScript in <head> inside document.ready, are both same thing?
Your <link> for CSS needed to be inside your <head>

im trying to call
.bind("click")
from an external .js file (js1.js).
here is the code:
js1.js:
$(function() {
$("p").bind("click",function(){
alert("The paragraph was clicked.");
});
});
page.html:
<head>

this code does not work in my files.
i found it from w3scools and it is working in their site:
<!DOCTYPE html>
<html>
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script>
$(document).ready(function(){

});
});
</script>
</head>
<body>
<p>Click me!</p>
</body>

how can i make it running from my external .js? any ideas?
thanks.
By the looks of it, you haven't added jQuery on your page yet. Add jQuery prior to your script.
<link rel="stylesheet" type="text/css" media="screen" href="./css/mystyle.css" />
<link rel="stylesheet" href="./css/global.css">
<script type="text/javascript" src="path/to/jQuery.js"></script>
<script type="text/javascript" src="./js/js1.js"></script>
<title>New WebPage</title>
If you forget to add this line
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
so add it in your <head> </head> section first. Otherwise your script could not work.
Bellow the complete code which working for me..
<html>
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script>
$(document).ready(function(){
$('#p').bind('click', function(){
alert('The paragraph was clicked.');
});
});
</script>
<style>
#p{cursor:pointer;}
</style>
</head>
<body>
<p id="p">Click me!</p>
</body>
</html>
