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 pretty new to JQuery and I may be missing a few things about it.
I have created a .php file which contains the header of my website. I included it into my main .php file. The "header.php" contains a 'div class= userbox_rectangle_full_header' that I would like to select from a JQuery loaded in the main "homepage.php".
I tried selecting it to show an alert on the click of the 'div'. When the Jquery is loaded in the "header.php", no problem, the alert correctly shows. But nothing happens when the .js file is loaded in "homepage.php".
Hope you'll be able to help me about what I'm missing.
The main homepage in which I load the JQuery:
<!DOCTYPE html>
<html>
<head>
<meta charset = "utf-8" />
<title>DSI Welcome</title>
<link rel="stylesheet" href="../css/homepage.css" />
</head>
<body>
<header>
<?php include 'header.php';?>
</header>
<div class="work_space" id="homepage_work_space">HOMEPAGE</div>
<div class="work_space" id="userpage_work_space">USERPAGE</div>
</body>
<script src="../js/jquery-3.3.1.js"></script>
<script src="../js/jquery_color_animation.js"></script>
<script src="../js/script/homepage_script.js"></script>
</html>
The "header.php" file which I include into the main "homepage.php":
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>Header</title>
<link rel="stylesheet" href="../css/header.css" />
</head>
<body>
<header>
<div class="userbox_rectangle_full_header"> </div>
</header>
</body>
<script src="../js/jquery-3.3.1.js"></script>
<script src="../js/jquery_color_animation.js"></script>
<script src="../js/script/header_animation.js"></script>
</html>
Finally, the JQuery code which is not working when loaded in the "homepage.php", but working when loaded in the "header.php":
$(document).ready(function() {
$('#homepage_work_space').on('click', function(){
alert('hi');
});
});
Thank you in advance !
There is some points in your code thats better to know .
Your html structure is wrong! simple html5 structure:
<!DOCTYPE html>
<html>
<head>
<title>Title of the document</title>
<!-- Your JQuery Main File -->
</head>
<body>
Content of the document......
</body>
</html>
Define your main jquery file in head of your body.
Your document has 2 <body> tag . (one your main body and other included from header.php )
Define your script files(except jquery that defined in head) in the footer , just before </body>
And in your header.php file dont define any script!
Have a good time!
It looks like you're loading in the scripts outside of the body. Make sure to load them inside your <head> tags.
here's a copy and paste from the revision history of the question, in order to demonstrate how the HTML markup should look alike, according to the op's description ...
file index.php:
<html>
<head>
<script src="../js/jquery-3.3.1.js"/>
<script src="../js/jquery_color_animation.js"/>
<script src="../js/script/homepage_script.js"/>
</head>
<body>
<?php include 'header.php'; ?>
<!-- further content goes here -->
</body>
</html>
file header.php:
<div class="userbox_rectangle_full_header">
<div class="work_space" id="homepage_work_space">HOMEPAGE</div>
<div class="work_space" id="userpage_work_space">USERPAGE</div>
</div>
file homepage_script.js:
$(document).ready(function() {
$('.work_space').on('click', function(){
alert('hi');
});
});
I'd suggest Twig or any other PHP template-engine, which are frameworks specialized on rendering HTML markup, including template bits, etc.
I am relatively new to both Bokeh/Python and HTML. I have created a served-based Bokeh plot which I want to display on a webpage. I have been following the instructions at https://docs.bokeh.org/en/latest/docs/user_guide/embed.html. In particular, I am using autoload_server to generate a script. However, when I place the script tag in the head of the HTML document (which is apparently correct, according to the last line at the above link):
<!DOCTYPE html>
<head>
<script
src="http://localhost:5006/autoload.js?bokeh-autoload-element=6abffe3c-d0dc-4e7b-80d3-0e7dc2d1b100&bokeh-absolute-url=http://localhost:5006&bokeh-session-id=bTinOCNtjuDagomoQgcw1EKJ7dUMkzSQJIRKozmGiqTc"
id="6abffe3c-d0dc-4e7b-80d3-0e7dc2d1b100"
data-bokeh-model-id="676400d3-9929-4d9e-aefe-2fb440f526d6"
data-bokeh-doc-id=""
></script>
</head>
<body>
</body>
</html>
The following error message appears on the webpage:
Bokeh Error
Error rendering Bokeh model: element with id '6abffe3c-d0dc-4e7b-80d3-0e7dc2d1b100' must be under body
So then I remove the script from the head and place it in the body. But this results in a completely blank webpage; the plot doesn't render at all.
Any help is greatly appreciated!
If we inspect the html generated by a basic example:
from bokeh.plotting import figure
from bokeh.resources import CDN
from bokeh.embed import file_html
plot = figure()
plot.circle([1,2], [3,4])
html = file_html(plot, CDN, "plot")
print(html)
It follows this format:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="https://cdn.bokeh.org/bokeh/release/bokeh-0.12.9.min.css" type="text/css" />
<script type="text/javascript" src="https://cdn.bokeh.org/bokeh/release/bokeh-0.12.9.min.js"></script>
</head>
<body>
<!-- generated div -->
<div class="bk-root">
<div class="bk-plotdiv" id="7a7b6ca9-3dec-430d-98f2-a0a7067c9ae0"></div>
</div>
<!-- generated script -->
<script type="text/javascript">
(function() {..})
</script>
</body>
</html>
The autoloading script instead replaces the generated <div> and <script>, and optionally replaces the static css and js references.
<!DOCTYPE html>
<html>
<head>
<!-- optional -->
<link rel="stylesheet" href="https://cdn.bokeh.org/bokeh/release/bokeh-0.12.9.min.css" type="text/css" />
<script type="text/javascript" src="https://cdn.bokeh.org/bokeh/release/bokeh-0.12.9.min.js"></script>
</head>
<body>
<!-- autoloading script -->
<script

I am trying to build my personal website using express and want to put a datepicker on one of the page.
I tried to change the ejs file of this page, however, nothing works.
I am wondering if it is because that the layout.ejs file exists, and wondering how can I just load jquery-ui in only of the ejs.file? Because I cannot find any related npm to install . Many thanks for answering！XD

There is another similar question, but I think the answer does not works for me.
node.js - DatePicker jquery UI not workinng
When I just use Express and change the index.ejs like the following, it works , but when there are many pages, it seems that it cannot be loaded...
<!DOCTYPE html>

node.js - DatePicker jquery UI not workinng
For whom run into the same problem, this is the reference.
I finally found the answer by checking the code.I was unable to load JQuery for in the layout.ejs, I retyped the following in order to load the bootstrap, but actually by using https://npmjs.org/package/twitter-bootstrap-node twitter-bootstrap-node, there is no-need to load the javascripts again. This may be a common problems for beginners in Node.JS like me.Hope this answer can be helpful to people who run into the same problem and the code is in the answer of the related problem.
<script src="/javascripts/jquery.js"></script>
<script src="/javascripts/bootstrap.js"></script>
<script src="/vendor/twitter/less/bootstrap.less"></script>
Hi look at this jsfiddle link http://jsfiddle.net/w7PHj/
you need to use like this....
$('#datepick').datepicker();
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
