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 would need help on attaching my .js document to my html document so that jQuery works on it, at the moment only normal JS is working.
This is the html document header (called "3i.html"):
<!PROCTYPE <!DOCTYPE html>
<html>
<head>
<title>3i.com</title>
<link rel="stylesheet" type="text/css" href="3i.css">
<script type="text/javascript" src="3i.js"></script>
</head>
The javascript file is called "3i.js".
Javascript commands like "alert" or "prompt" work fine, I just can't find a way to make jQuery code work.
Help is very much appreciated
Include the jQuery library and your .js file just before closing the body.
<!DOCTYPE html>
<html>
<head>
<title>3i.com</title>
<link rel="stylesheet" type="text/css" href="3i.css">
</head>
<body>
<script type="text/javascript" src="http://code.jquery.com/jquery-2.0.0.min.js"></script>
<script type="text/javascript" src="3i.js"></script>
</body>
</html>
I am a beginner programmer and I'm trying to make a web page that displays a JQuery Inline Date and Time Picker. As I was researching, I found this documentation: DateTimePicker. I followed the steps of first importing the JS and CSS files (after the closing body tag) using these tags:
<link rel="stylesheet" type="text/css" href="jquery.datetimepicker.css"/ >
<script src="jquery.js"></script>
<script src="jquery.datetimepicker.js"></script>
Following those tags, I called on my <input> from my Home.html file with the id of datetimepicker. Then using that id, I copied the code from the tutorial that creates the Inline DateTime Picker Calendar, like so:
$('#datetimepicker').datetimepicker({
inline:true
});
So my Home.html file looks like this:
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no">
<meta charset="utf-8">
<title>Home</title>
<!-- Compiled and minified CSS -->
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/materialize/0.97.0/css/materialize.min.css">
<!-- Compiled and minified JavaScript -->
<script src="https://cdnjs.cloudflare.com/ajax/libs/materialize/0.97.0/js/materialize.min.js"></script>
<link rel="stylesheet" type="text/css" href="./jquery.datetimepicker.css"/>
<script src="//code.jquery.com/jquery-1.10.2.js"></script>
</head>
<body>
<h3>Inline DateTimePicker</h3>
<input type="text" id="datetimepicker"/><input type="button" onclick="$('#datetimepicker3').datetimepicker({value:'2011/12/11 12:00'})" value="set inline value 2011/12/11 12:00"/><br><br>
</body>
<!-- CALLS JQUERY LIBRARY FOR DATE AND TIME PICKER -->
<!-- this should go after your </body> -->
<link rel="stylesheet" type="text/css" href="jquery.datetimepicker.css"/ >
<script src="./jquery.js"></script>
<script src="./jquery.datetimepicker.js"></script>
<script>
$('#datetimepicker').datetimepicker({
inline:true
});
</script>
</html>
However, when I run this code, I get an error that says:
TypeError: 'undefined' is not a function (evaluating '$('#datetimepicker').datetimepicker({
inline:true
})')
This is what is displaying:
This is what I want to display:
How can I get an Inline calendar to display on my Home.html page?
Put
<link rel="stylesheet" type="text/css" href="jquery.datetimepicker.css"/ >
<script src="./jquery.datetimepicker.js"></script>
between your <head></head> tags and remove
<script src="./jquery.js"></script>
I had the same sort of issue , If download the the source code from the XDSoft site
there is build folder , try using jquery.datetimepicker.full.js file from build folder .
You need to include jquery-ui.js
Do not confuse between jQuery versions. You first referenced jQuery here:
<script src="//code.jquery.com/jquery-1.10.2.js"></script>
And then you are doing it here:
<script src="./jquery.js"></script>
Please remove one. As the newer jQuery will be active and it doesn't have the plugin registered.
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

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>
<html lang="en">

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.

Hi look at this jsfiddle link http://jsfiddle.net/w7PHj/
you need to use like this....
$('#datepick').datepicker();
I am trying to use a tooltip jQuery plugin. This is what I have in <head> of index.html:
<head>
<title>Index</title>
<link rel="stylesheet" href="style.css" type="text/css" />
<script src="js/jquery-1.4.2.min.js" type="text/javascript"></script>
<script src="js/simpletip-1.3.1.min.js" type="text/javascript"></script>
<script src="js/homepage.js" type="text/javascript"></script>
</head>
And this is in js/homepage.js:
$(document).ready(function() {
// meaningless functions
$('.supported_hosts').simpletip({
fixed: true,
position: 'right',
content: 'test content.'
});
});
But for some reason, the tooltip doesn't show. But it does show if I include the tooltip function on the index page. Is there any way to get this working without having the tooltip function on the index page, but in an external file? Thanks.
I have never use the simplest plug in but i copy and pasted your header and your js code and everything seemed to work just fine.
I linked to the latest version of jquery and downloaded a fresh copy of simpletip.js and it worked with on the first try.
The only differences are/maybe:
- I don't know what your code looks like where you call 'supported_hosts' class in the html.
- The name of the simpletip.js file I didn't change it upon download, so I would check your file names and relative location.
Sorry there wasn't something more but what you have worked for me, here is the code I used in full incase this helps you:
HTML:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Index</title>
<link rel="stylesheet" href="style.css" type="text/css" />
<script src="http://code.jquery.com/jquery-1.4.2.min.js" type="text/javascript"></script>
<script src="jquery.simpletip-1.3.1.min.js" type="text/javascript"></script>
<script src="homepage.js" type="text/javascript"></script>
</head>
<body>
<span class="supported_hosts">Tool Tips here</span>
</body>
</html>
Javascript you gave:
$(document).ready(function() {
// meaningless functions
$('.supported_hosts').simpletip({
fixed: true,
position: 'right',
content: 'test content.'
});
});
I downloaded the simpletip.js here:
http://code.google.com/p/jquery-simpletip/downloads/detail?name=jquery.simpletip-1.3.1.min.js&can=2&q=
I would just double check your relative paths and class naming. Your code looks good.
Moving
<script src="homepage.js" type="text/javascript"></script>
to the end of the body seemed to solve the problem:
<body>
[code...]
<script src="homepage.js" type="text/javascript"></script>
</body>
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,
supervision
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.
