I am trying to display the results of a loop into my html from my JS file using Jquery. How do I do it..
here is my html code
<!DOCTYPE html>
<html>
<head>
<link href="css/bootstrap.css" rel="stylesheet" type="text/css">
<link href="css/styles.css" rel="stylesheet" type="text/css">

<title>Loops</title>
</head>
<body>
<div class="container">
<h1>Loops </h1>
<div id="results"> Here is your loop!
<p> <span class="loop"></span> </P>
</div>
</div>
</body>
</html>
here is my JS and JQuery code
$(document).ready(function(){
var n = parseInt(prompt("Give me a number from '1':"));
for (var i = 0; i < n; i++) {
$(.loop).append(i);
};
thanks
You're not targeting .loop correctly. It should be
$(".loop").append(i);
Instead of
$(.loop).append(i);
FIDDLE
You should use quotes when using a selector in the jQuery function:
$('.loop').append(i);

Issue I am having is as follows: This for loop should be putting a number in the address and counting up to 152 and then putting it full address as follows
<img src="http://pokeapi.co/media/img/1.png">
<img src="http://pokeapi.co/media/img/2.png">
and so on. What am I missing?
var webaddress = ['<img src="http://pokeapi.co/media/img/">'];
var text = "";
var i;
for (i = 0; i < 152; i++) {
text += webaddress[i] + ".png";
}
document.getElementById("Pokeman").innerHTML = text;
<!DOCTYPE html>
<html>
<head>
<title></title>
<meta charset="utf-8">
<link rel="stylesheet" type="text/css" href="style.css">

<script type="text/javascript" rel="script" type="script" href="script.jss"></script>
<script type="text/javascript" src='http://code.jquery.com/jquery-1.10.2.min.js'></script>
</head>
<body>
<div id="container">
<p id="Pokeman"></p>

You can create the webaddress as root string and replace it inside loop
var webaddress = '<img src="http://pokeapi.co/media/img/[index].png">';
var text = "";
for (var i = 1; i <= 152; i++) {
text += webaddress.replace("[index]", i);
}
document.write(text);
You are setting your javascript in the head - but the element that is referenced (#Pokeman) is not in the DOM yet - simply move the js block to the end - before the closing body tag. and since you are using jquery - i simplified the js and used it too.
EDIT - I just inserted your img code into the function so that it will render the images as the number increments.
<!DOCTYPE html>
<html>

<title></title>
<meta charset="utf-8">
<link rel="stylesheet" type="text/css" href="style.css"/>
</head>
<body>
<div id="container">
<p id="Pokeman"></p>
</div>
<script type="text/javascript" rel="script" type="script" href="script.jss"></script>
<script type="text/javascript" src='http://code.jquery.com/jquery-1.10.2.min.js'></script>
<script>
$(document).ready(function(){
for (var i = 1; i <= 152; i++) {
$("#Pokeman").append('<img src="http://pokeapi.co/media/img/'+ i + '.png"/>');
}
})

I am trying to use the JavaScript code from a .js file.
My code works fine when I keep this code in the .html file within the script tags.
What changes should I make when I move the script to a .js file.
HTML:
<!DOCTYPE html>
<html>
<head>
<title>Cat Clicker</title>
<script type="text/javascript" src="js/app.js"></script>
<link rel="stylesheet" type="text/css" href="css/style.css">
</head>
<body>
<div id='cc'><img src="images/cat1.png"><br /></div>
<div>The number of times you clicked the cat is:</div><br />
<div id='times'>0</div>
</body>
</html>
JS:
var pic = document.getElementById('cc');
pic.addEventListener('click', function() {
var count = document.getElementById('times').innerHTML;
count = parseInt(count) + 1;
document.getElementById('times').innerHTML = count;
}, false);
You must wrap that code inside window.onload to make it run after all the DOM elements are loaded.
window.onload = function() {
var pic = document.getElementById('cc');
pic.addEventListener('click', function() {
var count = document.getElementById('times').innerHTML;
count = parseInt(count) + 1;
document.getElementById('times').innerHTML = count;
}, false);
}
Else just move the script tag to the bottom of the page just above </body>
<!DOCTYPE html>
<html>
<head>
<title>Cat Clicker</title>
<link rel="stylesheet" type="text/css" href="css/style.css">
</head>
<body>
<div id='cc'><img src="images/cat1.png"><br /></div>
<div>The number of times you clicked the cat is:</div><br />
<div id='times'>0</div>
<script type="text/javascript" src="js/app.js"></script>
</body>
</html>
It's possible that your JavaScript code attempted to get an element which has not been rendered by the browser.
Solution # 1
You can try loading the JavaScript file after all elements have been rendered like this:
<!DOCTYPE html>
<html>
<head>
<title>Cat Clicker</title>
<link rel="stylesheet" type="text/css" href="css/style.css">
</head>
<body>
<div id='cc'><img src="images/cat1.png"><br /></div>
<div>The number of times you clicked the cat is:</div><br />
<div id='times'>0</div>
<script type="text/javascript" src="js/app.js"></script>
</body>
</html>
Solution # 2
You can also try using jQuery and do the following:
$(function(){
// and also convert this to its jQuery counterpart
var pic = document.getElementById('cc');
pic.addEventListener('click', function() {
var count = document.getElementById('times').innerHTML;
count = parseInt(count) + 1;
document.getElementById('times').innerHTML = count;
}, false);
})
If these didn't work, try using the Chrome developer tools and check if js/app.js is pointing to the JavaScript file
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="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>
I just want to set display property of one of my div to block based on event, by default its 'none'
Its not happening with error: Cannot set property 'display' of undefined
Below is my code. Please suggest.
HTML
<!DOCTYPE html>
<html >
<head>
<meta charset="ISO-8859-1">
<title>Sample Mod Pop UP</title>
<link rel="stylesheet" href="css/main.css" />
</head>
<body class="body">
<div class="popUp" id="id1">
<p>Are You Sure You Want to Quit?</p>
<span>✖</span>
</div>
<button onClick=closeWindown() class="btn">Close</button>
<script type="text/javascript" src="js/main.js"></script>
</body>
</html>
JavaScript
function closeWindown(){
document.getElementsByClassName("popUp").style.display="block";
}
getElementsByClassName gets a nodeList, so you have to iterate
function closeWindown(){
var elements = document.getElementsByClassName("popUp");
for (var i=elements.length; i--;) {
elements[i].style.display = "block";
}
}
As a sidenote, querySelectorAll('.popup') has better support, but is non-live.
I cant seem to find whats wrong. I have this html file used with google prettify. Both prettify.css and prettify.js are in the same directory as the html file
<html>
<head>
<script src="prettify.js"></script>
<link rel=StyleSheet href="prettify.css" type="text/css">
</head>
<body>
<pre class="prettyprint">
//Some sample text
for(int i = 0; i<10; i++){
//Do something
}
</pre>
</body>
</html>
And this is what it looks like
What am I missing to have the colors showing?
Thanks
Add onload="prettyPrint()" to your document's body tag.
<body onload="prettyPrint()">
Here's the code that will do the proper syntax highlighting
<html>
<head>
<!--<script src="prettify.js"></script>I commented out your links-->
<script src="https://cdn.rawgit.com/google/code-prettify/master/loader/run_prettify.js"></script>
<!--<link rel=StyleSheet href="prettify.css" type="text/css"> I commented out your links-->
</head>
<body>
<pre class="prettyprint">
//Some sample text
for(int i = 0; i<10; i++){
//Do something
}
</pre>
</body>
</html>
