I was actually trying to find some tutorials on Handlebar.js & I found this http://javascriptplayground.com/blog/2012/05/javascript-templating-handlebars-tutorial
But it is not actually working as expected.
What I am doing is I have an index.html file,
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" type="text/javascript" charset="utf-8"></script>
<script src="http://cloud.github.com/downloads/wycats/handlebars.js/handlebars-1.0.0.beta.6.js" type="text/javascript" charset="utf-8"></script>
<script src="app.js" type="text/javascript" charset="utf-8"></script>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Messing with Handlebars</title>
</head>
<body>
<script id="ajax-comment" type="text/x-handlebars-template">
<li>
<span class="meta">{{name}} on {{date}}</span>
<p>{{comment}}</p>
</li>
</script>
</body>
</html>
and an app.js which contains the code.
var source = $("#ajax-comment").html();
var template = Handlebars.compile(source);
var data = {
name : "Jack",
date : "12/04/12",
comment : "This is a really awesome tutorial. Thanks."
};
$("ul").append(template(data));
But all I am getting is a blank page. Any mistake I am making here? Detailed explanations would be helpful.
"ul" element doesn't exist, you must append it to something which actually exists.
just add a <ul></ul> somewhere in the body.

Seems like the jquery function was not able to access the element since the DOM wasnt loaded before the call was made. I tried some more combinations after the initial changes of calling the app.js code(without wrapping it inside a function) only after the DOM was loaded which worked.
For example I moved the script call just before the </body> which worked too.
... <script src="app.js" type="text/javascript" charset="utf-8"></script>
</body>
It also helped me to know whether we use HTML or XHTML as our document type, to understand this problem better.
try putting ref to your external JS at bottom, just above the closing body tag
eg
<body>
<ul></ul>
<!-- last thing on the page-->
<script src="app.js" type="text/javascript"></script>
</body>
this seemed to have solved it for me

Here is working example https://www.codeply.com/go/bp/lxa0FF9yhw# that I need to work in one html file.
I am using this template to merge HTML, Css and javascript:
<html>
<head>
<style type="text/css">
CSS goes here
</style>
<script type="text/javascript">
JS goes here
</script>
</head>
<body>
HTML goes here
</body>
</html>
But as a result I see all lines of table instead of pages.
Is this a problem with Bootstraping? I am including jQuery and javascript
<script src='http://ajax.aspnetcdn.com/ajax/jQuery/jquery-3.2.1.js'></script>
<script src='script.js' type="text/javascript"></script>
I still see all lines in a result. I tried this code in https://jsfiddle.net/tfyqwLkr/. It also shows all lines of table.
How to include all required elements in this case?
Try placing your Javascript just before the body end tag: </body>.
You might be calling DOM elements that haven't been parsed yet.
<html>
<head>
<style type="text/css">
/* CSS goes here */
</style>
</head>
<body>
<!-- HTML goes here -->
<script src='http://ajax.aspnetcdn.com/ajax/jQuery/jquery-3.2.1.js'></script>
<script src='script.js' type="text/javascript"></script>
<script type="text/javascript">
// JS goes here
</script>
</body>
</html>
EDIT: After posting your code, looks like you are trying to call size(), a deprecated method since jQuery 3.0.
Note: This method has been removed in jQuery 3.0. Use the .length property instead.
That throws some errors in the console. Change children.size() to children.length.
Check the updated Fiddle. (Line 23)
I have a React JS file which renders the following:
React.render(
<TreeNode node={tree} />,
document.getElementById("tree")
);
I reference it from a HTML file in the following way:
<!doctype html>
<html lang="en">
<link rel="stylesheet" href="app/listTree/treenode.css">
<h3>It's <code>TreeNodes</code> all the way down</h3>
<p>Edit the <code>tree</code> variable to change the tree</p>
<div id="tree">
<script src="/listTree/TreeNode.js"></script>
</div>
</html>
However, the contents of the JS file are not displayed.
I don't have experience in working with JavaScript.
Why is this happening?
Your script is already selecting the tree div element. So, there is no need to put a script tag inside of the div tag.
<!doctype html>
<html lang="en">
<head>
<link rel="stylesheet" href="app/listTree/treenode.css">
</head>
<body>
<h3>It's <code>TreeNodes</code> all the way down</h3>
<p>Edit the <code>tree</code> variable to change the tree</p>
<div id="tree">
</div>
<script src="listTree/TreeNode.js" type="text/jsx"></script>
</body>
</html>
You are also missing the <head> and <body> html tags.
Further, if you want to render jsx in your React code, you need to add <script> tags for them as well (and type="text/jsx" as a tag attribute):
<!doctype html>
<html lang="en">
<head>
<link rel="stylesheet" href="app/listTree/treenode.css">
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/0.13.3/react.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/0.13.3/JSXTransformer.js"></script>
</head>
<body>
<h3>It's <code>TreeNodes</code> all the way down</h3>
<p>Edit the <code>tree</code> variable to change the tree</p>
<div id="tree">
</div>
<script src="listTree/TreeNode.js" type="text/jsx"></script>
</body>
</html>
EDIT:
As a test to make sure your environment is working (and you don't just have a problem in your Component. Try to replace the code inside Treenode.js with this:
React.render(
<div>Testing...</div>,
document.getElementById("tree")
);
Then, you have no external dependencies. If you see Testing... rendered, you know that the environment is set up correctly.
Try to load your script after your div and not inside
<div id="tree">
</div>
<script src="/listTree/TreeNode.js"></script>
You need to load React also
Here is how I get it working add the following script
<script src="https://npmcdn.com/babel-core#5.8.38/browser.min.js"></script>
and change the type to 'text/babel'
<script type="text/babel" src="script.js"></script>
and the external js file should be with
.jsx
extension
please see working example here
You should not place a slash before "listTree".
So your script tag should look like this:
<script src="listTree/TreeNode.js"></script>
I'm really new to Javascrip/Jquery/Jqplot and I'm trying to learn by myself.
Then I have some questions,
Is this code enough to show a simple graph? Because it's not working, it shows a blank page.

document.write("<p>It works!!!</p>");
var plot1 = $.jqplot ('chart1', [[3,7,9,1,4,6,8,2,5]]);
});
</script>
</head>
<body>
<div id="chart1"></div>
</body>
</html>
i used this library too for a project, its really good!.. i just check the example that you post it and i found out what it was causing you an error, you only need to change the document.write sentence, if you use for example the console.log function it will work.
ex.
$(document).ready(function(){
console.log("It works!!!");
var plot1 = $.jqplot ('chart1', [[3,7,9,1,4,6,8,2,5]]);
});
Another thing important is that this library uses jquery, so you will need to reference all the js files of jqplot after the jquery reference to avoid the JQuery no defined error.
I hope it helps!
You need to remove
document.write('<p>It works!!!</p>');
Or replace it by
document.write('<p>It works!!!</p><div id="chart1"></div>');
Your document.write statement is replacing the body part of your html page by what you have mentionned (here '< p >It works!< / p >).
Thus your html page isn't containing any div with "chart1" id anymore.
As you specify to jqplot to plot your graphic in a div identified with "chart1" (and document.write statement has erased it) it is a normal behaviour not to be able to see your graphic.
PS : It is not compulsory to include all off jqplot plugins to draw your graph. If it will not became more complicated, I suggest you to include only "css/jquery.jqplot.css" and "js/jquery.jqplot.js".
For more complicated graph, include only necessary plugins (for example "js/jqplot.dateAxisRenderer.js" if you need to work with date axis).
Edit
Please see working jsFiddle here, try to play with the two "document.write" lines (try to comment and uncomment them).
I've been having trouble implementing jQuery - in particular, replicating this exercise from Code Academy. I understand from this other question on Stack Overflow that the <script> referencing jQuery.js needs to be placed before the <script> referencing the local JavaScript file in order for the $(document).ready(); to be recognized.
As such, here is index.html:
<!DOCTYPE html>
<html>
<head>
<title>Behold!</title>
<link rel='stylesheet' type='text/css' href='http://code.jquery.com/ui/1.9.1/themes/base/jquery-ui.css'/>
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.9.1/jquery-ui.min.js" type="text/javascript"></script>
<script type='text/javascript' src='index.js'></script>
</head>
<body>
<div id="menu">
<h3>jQuery</h3>
<div>
<p>jQuery is a JavaScript library that makes your websites look absolutely stunning.</p>
</div>
<h3>jQuery UI</h3>
<div>
<p>jQuery UI includes even more jQuery goodness!</p>
</div>
<h3>JavaScript</h3>
<div>
<p>JavaScript is a programming language used in web browsers.</p>
</div>
</div>
</body>
</html>
And then here is my index.js:
$(document).ready(function() {
$("#menu").accordion({collapsible: true, active: false});
});
In both Chrome and IE, this displays as a entirely blank page, with no trace of the jQuery accordion or text whatsoever.
Please let me know if I'm overlooking something - I really appreciate the help. Thanks!
This:
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.9.1/jquery-ui.min.j" type="text/javascript"></script>
Should be this:
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.9.1/jquery-ui.min.js" type="text/javascript"></script>
I don't know if this error is just from copy'n'paste but the file extension is incorrect (should be "js" and not "j").
Furthermore you do not include jQuery itself (only jQuery UI).
Use the following head-Area:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.9.1/jquery-ui.min.js" type="text/javascript"></script>
<script type='text/javascript' src='index.js'></script>
These work for me.
I have an h2 element with an id of title and I have the following script:
<script type="text/javascript">
$(document).ready(function(){
$("#title").css("background-color","red");
)};
</script>
The background-color is not changing though and I can't figure out why?
<html>
<head>
<title>Table Sorter</title>
<script type="text/javascript" src="/js/jquery-1.3.2.min.js"></script>
<script type="text/javascript" src="/js/jquery.tablsorter.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("#title").css("background-color","red");
)};
</script>
</head>
<body>
<h2 id="title">Table Sorter</h2>
</body>
</html>
<script type="text/javascript">
$(document).ready(function()
{
$("#title").css("background-color","red");
$("#myTable").tablesorter();
}
);
</script>
Replace
<link type="text/javascript" src="/js/jquery-1.3.2.min.js"/>
with
<script type="text/javascript" src="/js/jquery-1.3.2.min.js"></script>
You also have a syntax error in your jQuery function at the closing brackets. They should be
$(document).ready(function(){
$("#title").css("background-color","red");
});
If that still does not fix your problem, then put an alert in there like this...
$(document).ready(function(){
alert("Howdy!");
});
If you do not see the alert message, then your jQuery script is not loaded, which means the relative path in the SRC attribute is incorrect.
It seems you've made another typo:
<title>Table Sorter</table>
^^^^^
Replace table with title:
<title>Table Sorter</title>
Can you get it working without jQuery? Try:
document.getElementById("title").style.backgroundColor = "#F00";
instead of your current script. If this does not work, check that you have well-formed HTML.
UPDATE: now that you've posted your HTML, I can see that you need to use a script tag instead of a link tag to import jQuery
Replace
<link type="text/javascript" src="/js/jquery-1.3.2.min.js"/>
with
<script type="text/javascript" src="/js/jquery-1.3.2.min.js"/>
Here you go. Other people have pointed out some small problems you had, such as using a link tag where you need a script tag, etc. This code works for me:
<html>
<head>
<title>Table Sorter</title>
<script type="text/javascript" src="js/jquery-1.3.2.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("#title").css("background-color","red");
});
</script>
</head>
<body>
<h2 id="title">Table Sorter</h2>
</body>
</html>
It looks like there was a typo in your code at the end of your $(document).ready section where you had )}; instead of });. If you use Firefox you can open up the error console and view any Javascript errors or warnings.
Ok, I figured it out and I don't know why it is was happening. Below the JQuery script tag, I had another script tag:
<script type="text/javascript" src="/js/jquery.tablsorter.min.js"/>
When I removed the above, it worked. But I don't know why?
