I'm trying JQUERY on my machine, but for some reason, nothing seems to work. Here's the test file:
<html>
<head>
<script type="text/css" src="jquery.js">
</script>
<script type="text/javascript">
$("p").mouseover(function () {
$(this).css("color","black");
});
$(document).ready(function(){
$("body").css("background-color","black");
$("body").css("color","white");
});
</script>
</head>
<body>
<h1>This is a test</h1>
<p>Roll over me!</p>
</body>
</html>
Nothing in there works. Also, if anybody wants to know, accessing through my domain and through the local both don't work. I'm really confused, because I copied most of that code off the internet, just in case there was something wrong with my typing.
For some reason, firefox is throwing this error:
Code: Evaluate
$ is not defined
http://hussain.mooo.com/jq.html
Line: 6
$ is not defined
http://hussain.mooo.com/jq.html
Line: 6
New code (moved the p onmouseover handeler)
<script src="jquery.js" type="text/css">
</script>
<script type="text/javascript">
$(document).ready(function(){
$("p").mouseover(function () {
$(this).css("color","black");
});
$("body").css("background-color","black");
$("body").css("color","white");
});
</script>
Specify correct type for javascript file:
<script type="text/javascript" src="jquery.js"></script>
Update
You're currently using type="text/css" as content type for javascript file which is incorrect. Try to copy above code into your script.

Install firebug and see what it tells you in the Console tab.
You should move the attachment of the mouseover handler into $(document).ready(...) because the paragraph won't necessarily exist until the document is ready and so no handler can be attached to it.
Download the latest version of jQuery "jquery-1.3.2.min.js" and link the file correctly. and try this,
<script type="text/javascript">
$(function(){
$("p").mouseover(function () {
$(this).css("color","black");
});
$("body").css("background-color","black");
$("body").css("color","white");
});
</script>

JSFiddle demo: https://jsfiddle.net/cr33q8v7/
$("#findMyWeather").click(function() {
alert("button clicked");
});
All I'm trying to verify is if the JQuery is working and I'm not getting any pop-up that says button clicked, so it would appear the syntax is wrong, but I've checked it multiple times and it looks right.
So if I include the library on JSFiddle, then why does the below code in the HTML file not run, as it appears the function is identical and these pointers both direct to the library:
<script src="//code.jquery.com/jquery-1.11.0.min.js"></script>
<script src="//netdna.bootstrapcdn.com/bootstrap/3.1.1/js/bootstrap.min.js"></script>
<script>
$("#findMyWeather").click(function() {
alert("button clicked");
});
</script>
So the // pointers didn't reference (this is what the teacher instructed). When I changed to `https:``, then it functioned correctly:
<script src="https://code.jquery.com/jquery-3.1.0.min.js"></script>
<script src="https://netdna.bootstrapcdn.com/bootstrap/3.1.1/js/bootstrap.min.js"></script>
I need another set of eyes, or else I'm missing something else and just don't see it.
You need to include the jQuery library in JSFiddle.
Click the gear that says Javascript and choose the version of jQuery that suits you.
Your fiddle doesn't actually include jQuery via a script tag.
e.g. add: <script src="https://code.jquery.com/jquery-3.1.0.min.js"></script> to your HMTL
you must add below line after last div between body tag :
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4
/jquery.min.js"></script>
Here is Demo
Add the cdn link for Jquery. Without jquery it will not work. You can add it to the before end of body tag.
Add:<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
use jquery online by adding <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>.
<html>
<head></head>
<title></title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<body>
<button id="check">Click on me to check if jquery is working ....!</button>
</body>
<script type="text/javascript">
$("#check").click(function(){
alert("yep, jquery is working");
});
</script>
</html>
every thing looks fine please select jquery in fiddle then try it
and please add this script code in your file
< script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js" ></script>
I am creating a website, I am using a NodeJS server. In my public folder I have a script named website.js and it has the jQuery code to give a console.log when the h1 is clicked. (Code Below). But when I click on the h1 in the browser it does not work. The file is loaded properly, gives no 404 error and my CSS stylesheet works fine.
Further Testing: I did a simple test to see if it would give back the text when I called the variable (test code below) it responds with: "" (two quotation marks) so it must not be recognizing it.
//Test code
var xyz = $("#testh1").text();
//jQuery Code
$("#testh1").on("click", function(){
console.log("Clicked");
});

You need to load jQuery before your script.
<script src="https://path-to-jquery"></script>
<script src="/javascripts/website.js"></script>
You need to wait for the DOM to be ready before accessing any elements in it. You can either do it with the following code:
$(document).ready(function() {
$("#testh1").on("click", function(){
console.log("Clicked");
});
});
or by putting your <script>s at the bottom of the <body> instead of in the <head>.
<script src="https://path-to-jquery"></script>
<script src="/javascripts/website.js"></script>
</body>
You're getting an empty string in your test code because your #testh1 element hasn't been loaded yet.
I have downloaded the 1.11.3.min.js file and placed it in the same file where I have kept the HTML and script files. Before writing this code I have practiced jQuery a lot and those time I have succeeded, but this time I can't run it.

I have downloaded the 1.11.3.min.js file and put in the same file where i have kept the HTML and script files.Before writing this code i have practiced jQuery a lot and those time i have succeeded.But this time i have failed to run it.
Just replace this line of code
$document.ready(function(){
with this line
$(document).ready(function(){
You did't add brackets around document
May be you want do this:
$(document).ready(function(){
$("#slide").click(function(){
$(this).slideUp(400);
});
});
First, I recommend using CDN's for jQuery (less loading time), it can be found here
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script>
then, you forgot to end your function, and you forgot () around document
your script should look like this:
$(document).ready(function() {
$("#slide").click(function() {
$(this).slideUp(400);
});
});
I have placed one javascript (hide.js) in my html Page ... Hide function is not working .My scripts are in right order
My code is as per tutorial
<!DOCTYPE html >
<html lang="en">
<head>
<meta charset="utf-8" />
<title>jQuery Example </title>
</head>
<body>
<p id="paragraph ">
This is Paragraph</p>
<script type="text/javascript" src="http://localhost/WebApplication2/js/hide.js"></script>
<script type="text/javascript" src="http://localhost/WebApplication2/js/jquery-1.7.1.min.js"></script>
<script type="text/javascript" src="http://localhost/WebApplication2/js/toggle.js"></script>
</body>
</html>
hide.js
$('#paragraph').click(function () {
$('#paragraph').hide();
});
I have test it with Firebug lite on Chrome .. Console doesnt show any error .. in script is also showing external scripts ...Other script are working fine
I have rearranged script Order like this
<script type="text/javascript" src="http://localhost/WebApplication2/js/jquery-1.7.1.min.js"></script>
<script type="text/javascript" src="http://localhost/WebApplication2/js/toggle.js"></script>
<script type="text/javascript" src="http://localhost/WebApplication2/js/hide.js"></script>
still it is not working ..
i couldnt find any relevant link ..whats wrong ..Please Suggest
Because, you included hide.js before jquery.js. You should include hide.js after jquery.js like so...
<script type="text/javascript" src="http://localhost/WebApplication2/js/jquery-1.7.1.min.js"></script>
<script type="text/javascript" src="http://localhost/WebApplication2/js/toggle.js"></script>
<script type="text/javascript" src="http://localhost/WebApplication2/js/hide.js"></script>
In case you must include hide.js first before jquery.js. Change your code to
$( document ).ready(function() {
$('#paragraph').click(function () {
$('#paragraph').hide();
});
}
In this way, your script will work after whole page is loaded.
Or, similarly you can use.
$(function() {
// Your Code
});
order should be, include jquery main file all above.
<script type="text/javascript" src="http://localhost/WebApplication2/js/jquery-1.7.1.min.js"></script>
<script type="text/javascript" src="http://localhost/WebApplication2/js/hide.js"></script>
<script type="text/javascript" src="http://localhost/WebApplication2/js/toggle.js"></script>
core jQuery file must be include before any other plugin as they may use core jquery methods internally.
You have a space in the id of your paragraph tag, which is invalid, so your javascript cannot select that paragraph using that id.
You need to remove the space from your id attribute.
Order of script - hide.js is using jQuery so it has to be included after jquery.js
<script type="text/javascript" src="http://localhost/WebApplication2/js/jquery-1.7.1.min.js"></script>
<script type="text/javascript" src="http://localhost/WebApplication2/js/toggle.js"></script>
<script type="text/javascript" src="http://localhost/WebApplication2/js/hide.js"></script>
Your browser console should show you an error saying something like Uncaught ReferenceError: $ is not defined
your id has space.remove it and try again
<p id="paragraph ">This is Paragraph</p>
it should be like this
<p id="paragraph">This is Paragraph</p>
I have discovered a very strange thing which probably could be the cause. It should certainly help you.
In your code, I see you have only external JS files. After those external files, include an empty tag. It should work.
Cause is not known but external JS does not get included at times if you do not have inline or empty script tag. It will be very interesting to dig in more. Let me update once I figure out.

Should the following display "Test" in a message box? If not, what changes should I make?
<html>
<base href="http://www.google.com"></base>
<body>
<script language="JavaScript" type="text/javascript" src="test.js"></script>
</body>
</html>
test.js contains:
alert("Test");
Yes. See here I've inserted this into a jsFiddle example. Next time try to just do it instead of asking a question. You can see the example here
alert("Test");
is the command that does a msg box!
