I'm attempting to create a main js controller that includes all needed js files for my application to keep everything as structured as possible.
I thought this would work, but it doesn't seem to append anything to head:
HTML:
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<link rel="stylesheet" type="text/css" href="../static/css/main.css" />
<link rel="stylesheet" type="text/css" href="../static/css/sub/navbar.css" />
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript" src="../static/js/includes.js"></script>
<title>Untitled Document</title>
</head>
As you can see includes.js is imported after jQuery from Google's CDN
Contents of includes.js:
var scripts = ['../static/js/functions/notifications.js', '../static/js/functions/subnavbar.js'];
$(document).ready( function() {
var iterate = scripts.length;
for(i = 0; i < iterate; i++) {
$('head').append('<script type="text/javascript" src="' + scripts[i] + '"></script>');
}
});
I have no idea why it's not appending the contents of the array scripts to head. I tested out the script by appending the contents to body (see this jsFiddle).
Any answers as to why it's not working, or edits to make it work would be greatly appreciated :)!
Something to consider: this problem has been solved for you already, and an awesome JavaScript library already exists. It's called Require JS.
I strongly recommend checking it out to see if it'll work for your requirements before rolling your own dependency loader.
You are using jQuery, why not using $.getScript?
This works fine in this example: http://jsfiddle.net/x6rCr/

I'm having problems in using mathquill on my website.
I'm new to this.
I'm stuck in this part
<link rel="stylesheet" type="text/css" href="/path/to/mathquill.css">`
<script src="/path/to/mathquill.min.js"></script>
I dont know what to put on the hrefs because I'm not seeing those files from mathquill file i got from github..
i downloaded the latest mathquill files and its inside htdocs(xampp) or www(wamp) together with my index.php.
Do i have to place my index.php inside mqthquill-0.10.1 folder?
Here is my
<link rel="stylesheet" href="/path/to/mathquill.css"/>
<script src="jquery-3.2.1.min.js"></script>
<script src="/path/to/mathquill.js"></script>
I appreciate if someone could give me the steps on how to use mathquill.
thanks in advance
Option 1
You can either download the mathquill.css and mathquill.js files from github and use them from your directory.
If you have your folder (directory) structure as below:
appFolder
.. scripts
.... mathquill.js
.... index.js
.. css
.... mathquill.css
myPage.html
Here's how you would reference the CSS and JS files:
<link rel="stylesheet" type="text/css" href="/css/mathquill.css">`
<script src="/scripts/mathquill.min.js"></script>
An easy way to check if your paths are correct is to put the entire URL in the browser's address bar. For example, if you are browsing the page as:
www.mydomain.com/mypage.html
The links to css and js files in the example folder structure I mentioned above would be:
www.mydomain.com/scripts/mathquill.js
www.mydomain.com/css/mathquill.css
Option 2
You could use the CDN to get the JS and CSS files on your page. Just copy the below two lines on to your html page, and you are ready to go.
<link rel="stylesheet" type="text/css" href="https://cdnjs.cloudflare.com/ajax/libs/mathquill/0.10.1/mathquill.min.css">`
<script src="https://cdnjs.cloudflare.com/ajax/libs/mathquill/0.10.1/mathquill.min.js" type="text/javascript"></script>

Sorry for the basic question. I'm new to coding and I've already googled "how to run code from node modules" "how to use code from node modules" etc. for a few hours without any real progress.
Basically, I want to create a editable div with the text editor (https://github.com/yabwe/medium-editor) and I already manually downloaded and followed the directions to inserting the code inside the editor (can be found on the GitHub page).
Here is my code for the editable div in its entirety:
HTML:
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<link rel="stylesheet" type="text/css" href="post.css">
<script src="other.js"></script>
<link rel="stylesheet" href="css/medium-editor.css">
<link rel="stylesheet" href="css/themes/default.css">
<script src="js/medium-editor.js"></script>
<div contenteditable="true" class= ".editable" id="posteditor"> <p> test words</p></div>
</body>
Javascript (other.js -referenced in html code):
var elements = document.querySelectorAll('.editable'),
editor = new MediumEditor('.editable');
I also copy and pasted the files from the downloaded file into a new file folder holding the HTML/CSS/Javascript code for the editable div (not sure if this even makes a difference).
Thank you so much for helping a new coder.
EDIT: Figured it out! My paths were in the wrong order and I wasn't referencing some of the necessary code in the
You need some simple html css js basics knowledge to start dealing with such code
here are some tips:
*put link tag in the head
*put script tags in before the ending of the body
try now to run this code and double tap the word you want to edit
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<link rel="stylesheet" href="//cdn.jsdelivr.net/medium-editor/latest/css/medium-editor.min.css" type="text/css" media="screen" charset="utf-8">
</head>
<body>
<div class="editable"><h4>hi I am editable</h4></div>
<script src="//cdn.jsdelivr.net/medium-editor/latest/js/medium-editor.min.js"></script>
<script>var editor = new MediumEditor('.editable');</script>
</body>

Uncaught ReferenceError: $ is not defined?

How to fix '$' was used before it was defined in both jslint and jshint using coding?
(2 answers)
Closed 8 years ago.
This is my first time trying to use JQuery and I was trying to add an event when the document is ready, but every time it says:
"$ was used before defined".
I don't know how to solve it. I tried different solutions on the internet but couldn't find any. Don't really know what I am doing wrong.
I referenced the HTML file to the js file like this
<!DOCTYPE html>
<html>
<head>
<title>Experimenting with Javascript</title>
<script type="text/javascript" src="script.js"></script>
<link type="text/css" rel="stylesheet" href="main.css" />
</head>
and this is my script
$(document).ready(function () {
"use strict";
$('div').mouseenter(function () {
$(this).animate({
height: '+=10px'
});
});
});
Reference the JQuery library in your page, like this
<script src="https://code.jquery.com/jquery-2.1.1.min.js"></script>
Include this tag above the script tag of your js file
Add JQuery library (http://jquery.com/)
Adding a event on every div in your app - rethink this. Add a class or something, and add it to a single element container, or a body, but don't add it to most common element.
You should organize your HTML DOM like that :
<!DOCTYPE html>
<html lang="en" class="">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Experimenting with Javascript</title>
<link type="text/css" rel="stylesheet" href="main.css" />
</head>
<body>
<script src="//code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
<script type="text/javascript" src="script.js"></script>
</body>
1.You should call Jquery library before calling your project JS file's.
The problem here is that you are using jQuery without actually including that library of code in your HTML file.
<!DOCTYPE html>
<html>
<head>
<title>Experimenting with Javascript</title>
<link type="text/css" rel="stylesheet" href="main.css" />
</head>
<body>
<script src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
<script type="text/javascript" src="script.js"></script>
</body>
Just to clarify, jQuery is a library that acts on top of JavaScript so you would need to include that library above your own scripts that use it.
NOTE: It is best practice to include your scripts just before your closing body tags.
I am having trouble linking a javascript file to a dynamic website i made through php. My file structure is simply just:
index.php, css folder (which is working correctly), jscript folder (does
not work) and a pages folder (has all my pages)
My pages are simple just
header.php, registrationContent.php and footer.php
My index just includes all 3 php and it works perfectly fine. My problem is no matter what I do, whether inline, or soft coded javascripting it does not work. I am certain my syntax in the javascript is fine, its just the linking.
My header:
<!DOCTYPE html>
<html lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Safe Drive Website</title>
<link href="css/stylesheet.css" rel="stylesheet" type="text/css" />
<link href="css/regStyle.css" rel="stylesheet" type="text/css" />
<script src="jscript/javascripts.js" type="text/javascript"></script>
</head>
<body>
<div class="topBar" id="topBar"><input type="Submit" value="Contact Us" class="topNavButton"/></div>
<div id="bannerText"><h1 class="mainHeader">SafeDrive</h1><h2 class="subHeader">Developer's Tool</h2></div>
I close the tags in the footer.php
Javascript files are included directly in your html page.
use the following line in your html page:
<html>
<head>
<script type="text/javascript" src="path/to/your/javascript/file.js"></script>
</head>
...
This is probably uncommon, but I thought of answering my own question because I found a solution, so that anyone else having the same problem could try mine.
Basically, it was loaded, the only problem was that the javascript functions weren't loaded and so to do that, i had to add:
window.onload = myJscriptFunction();
on any tag (body, footer etc. refer to w3schools for that information)
I do hope this helps anyone facing the same problem ^_^
my file beginning looks like this:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>My title</title>
<link rel="stylesheet" type="text/css" href="css/style.css" />
<script src="js/update.js" type="text/javascript"></script>
<!-- sifr -->
<link href="sifr207/sIFR-screen.css" rel="stylesheet" type="text/css" media="screen" />
<script src="sifr207/sifr.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function()
{
if(typeof sIFR == "function")
{
sIFR.replaceElement("sifr", named({sFlashSrc: "sIFR-2.0.7/corporateacon-reg.swf", sColor: "#FF0000" , sWmode: "transparent"}));
};
});
</script>
<!-- -->
</head>
I really do not understand why the '$(document).ready(function()' is not found, because I implement sifr.js BEFORE that call.
Any suggestions?
I would appriciate it, really!
shoutz,

you do not have jQuery.js included in your file!
Since SIFR is a jQuery plugin, you have to load the base library before sifr.js.
Try adding <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript></script> at the beginning of your script.
Seems like you didn't include any reference to JQuery before that call, that's why '$' is undefined. Try to add this before:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.js" type="text/javascript"></script>
Because sIFR doesn't implement a $ function. You probably mean to use Prototype.js, jQuery, or some other library that uses that badly named variable.
$(document).ready(callback) is a method provided by the jQuery library to run callback when the document parsing has completed. It looks like you don't have a script referencing jQuery in your file, so this method is not available.
Simply add jQuery to your head before sifr is loaded.
