I tried everything mentioned in this forum, Tried newer versions of jQuery Checked every spelling spent two hours to find out the problem but got no result.
Move Jquery to the <head>. If not, you could try
(function($) {
$(function() {
$('h1').click(function() {
$(this).css('background-color', '#ff0000')
})
});
})(jQuery);
This will make sure your Global jQuery variable is bound to the "$".
(function($) {
$(function() {
$('h1').click(function() {
$(this).css('background-color', '#ff0000')
})
});
})(jQuery);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<h1>Hello World</h1>
You could also load the script externally. I often find this to work better with jQuery.
You need to include jQuery before using it. Move the <script> tags that defined after footer into <head> before script that you try to run.
<head>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$('h1').click(function() {
$(this).css('background-color', '#ff0000')
});
});
</script>
</head>
<body>
<h1>Click Me</h1>
</body>
Check if your file is REALLY loaded
Add a new file, and only import jQuery from googleapi. Then, go to your browser's developer tools (F12), abd in console try to execure '$'. If it's not throwing an error, go to 4. If it is throwing an error, go to 3.
Check your internet connection to googleapi: Open the jQuery file in your browser, and check if it is loaded properly.
Try add 'refer' to your script tag like this:
If error still occurs, feel free to comment below.
Insert your script file/code just below the jQuery library file link
<h1>Heading</h1>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script>
jQuery(document).ready(function() {
jQuery('h1').click(function() {
jQuery(this).css('background-color', '#ff0000')
})
})
</script>
It happened because jQuery is not properly installed to be sure before coding run the code below. If it gives you alert message "jQuery is installed correctly" you are good to go.
<head>
<title>JQuery</title>
<script src="jquery-3.2.1.min.js"></script>
</head>
<body>
<script type="text/javascript">
if(typeof jQuery=="undefined"){
alert("jQuery is not installed ")
}else {
alert("jQuery is installed correctly")
}
</script>
</body>

I am using HTML, CSS, and JS. I am trying to use the JQuery library but it is not being recognized by my html file. I am inserting it above my external .js file, so I don't think that is the issue. Here is what is in my HTML file:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="js/tether.min.js"></script>
<script src="js/bootstrap.min.js"></script>
<script src="js/main.js"></script>
This is what is in my JS file:
$(document).ready(function() {
$(window).scroll(function() {
if ($(window).scrollTop() > 970) {
$('.navbar').addClass('navbar-fixed-top');
}
});
});
My code editor is throwing errors when I save this js file because of errors like:
-'$' was used before it was defined.
-Expected exactly one space between 'fucntion and '('
Anyone know what the issue might be? Thanks in advance.
This might not be the issue, but you may wish to attempt to load the jquery file by HTTPS (https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js), especially if you are running your site on an HTTPS connection.
Otherwise, it seems to work when I test it:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script>
$(document).ready(function() {
$(window).scroll(function() {
if ($(window).scrollTop() > 970) {
$('.navbar').addClass('navbar-fixed-top');
}
});
console.log("done!")
});
</script>
The problem is in your <script> tag, as #B.Fleming said maybe the HTTPS protocol. This tag is working:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
put this in top of your code where you are using jQuery
/* global $ */
alternativ is prefixing it with window
I don't like using the global $ sign cuz other libs are using it as well. what i usably dose is getting the $ from the closure function like this
jQuery(function($){
// document is ready, You may use jquery here and now
$('body')
})
and to get away with jQuery is not defined use window.jQuery instead
ps, always load stuff from https when possible
I am playing around with an html template and I have noticed that the developer doesn't use RequireJS or anything else to require and call different functions from other node files. Instead, they used this in the html file to initialise and call the function:
<script src="../../assets.js/test.js"></script>
<script type="text/javascript">
$(document).ready(function(){
test.initSomeFunction();
});
</script>
And I've got the below code in assets/js/test.js which defines initSomeFunction in javascript:
test = {
initSomeFunction: function() {
//Some code
}
initAnotherFunction: function() {
//More code
}
}
(It would be helpful if someone can tell me what this method is called so that I can research it more.)
My problem arises when I try to do the same thing in my node app in the home directory /main.js. The node app works fine on its own but when I add something like this:
test2 = {
initMyFunction: function() {
console.log("I finally decided to work! Good luck...");
}
}
and modify my html file like this:
<script src="../../main.js"></script>
<script type="text/javascript">
$(document).ready(function(){
test.initSomeFunction();
test2.initMyFunction();
});
</script>
then it won't work. Can someone please point me to the right direction as I don't even know what to Google. I am trying to avoid using RequireJS or anything else as I am a total beginner and the method that the developer used sounds so simple and tempting.
I wish this answer will help you:
I am using express, so I do this to solved your problem!
main.js file's position:
modify app.js add:
app.use(express.static(path.join(__dirname, '/')));
Then, in the view file:
<html>
<head>
<script src="public/javascripts/jquery-1.10.2.min.js"> </script>
<script src="main.js"></script>
</head>
<body>
<script>
$(function () {
//test.initSomeFunction();
test2.initMyFunction();
})
</script>
</body>
</html>
Open the chrome Developer Tools. You will see the result.
I'm having trouble running javascript from an external file. Here's where it's included in the html:
<div id="article-author-list" class="article-author-list">
<#list authorGroups as authorGroupItem>
<#authorGroup item=authorGroupItem/>
</#list>
<script type="text/javascript">alert('Hello??');</script>
<script type="text/javascript" src="/js/article/truncateAuthors.js"> </script>
</div>
Whereas here's truncateAuthors.js:
alert('Found the script!!!');
$(window).load(function () {
alert('Found the script.');
});
$(document).ready(function () {
alert('Document is ready');
});
$(function(){
alert('Running the script');
});
When the html is loaded, the only alert is 'Hello??' from the inline script. How can I get the external file to execute?
Before call your javascript please add this
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
to your file it will work fine. this is jquery library file that we have to use when we are writting code in jquery
I found it! The project was using requireJS and I needed to add it to the declaration. Thanks for all your answers :)
I am having an issue getting a dialog to work as basic functionality. Here is my jQuery source imports:
<script type="text/javascript" src="scripts/jquery-1.9.1.js"></script>
<script type="text/javascript" src="scripts/jquery-ui-1.11.1.js"></script>
<script type="text/javascript" src="scripts/json.debug.js"></script>
Html:
<button id="opener">open the dialog</button>
<div id="dialog1" title="Dialog Title" hidden="hidden">I'm a dialog</div>
<script type="text/javascript">
$("#opener").click(function() {
$("#dialog1").dialog('open');
});
</script>
From the posts around seems like as a library import issue. I downloaded the JQuery UI Core, Widget, Mouse and Position dependencies.
Any Ideas?
Be sure to insert full version of jQuery UI. Also you should init the dialog first:
$(function () {
$( "#dialog1" ).dialog({
autoOpen: false
});
$("#opener").click(function() {
$("#dialog1").dialog('open');
});
});
<script src="https://code.jquery.com/jquery-1.11.1.min.js"></script>
<script src="https://code.jquery.com/ui/1.11.1/jquery-ui.min.js"></script>
<link rel="stylesheet" href="https://code.jquery.com/ui/1.11.1/themes/smoothness/jquery-ui.css" />
<button id="opener">open the dialog</button>
<div id="dialog1" title="Dialog Title" hidden="hidden">I'm a dialog</div>
if some reason two versions of jQuery are loaded (which is not recommended), calling $.noConflict(true) from the second version will return the globally scoped jQuery variables to those of the first version.
Some times it could be issue with older version (or not stable version) of JQuery files
Solution use $.noConflict();
<script src="other_lib.js"></script>
<script src="jquery.js"></script>
<script>
$.noConflict();
jQuery( document ).ready(function( $ ) {
$("#opener").click(function() {
$("#dialog1").dialog('open');
});
});
// Code that uses other library's $ can follow here.
</script>
If you comment out the following code from the _Layout.cshtml page, the modal popup will start working:
</footer>
#*#Scripts.Render("~/bundles/jquery")*#
#RenderSection("scripts", required: false)
</body>
</html>
Change jQueryUI to version 1.11.4 and make sure jQuery is not added twice.
I just experienced this with the line:
$('<div id="editor" />').dialogelfinder({
I got the error "dialogelfinder is not a function" because another component was inserting a call to load an older version of JQuery (1.7.2) after the newer version was loaded.
As soon as I commented out the second load, the error went away.
Here are the complete list of scripts required to get rid of this problem.
(Make sure the file exists at the given file path)
<script src="#Url.Content("~/Scripts/jquery-1.8.2.js")" type="text/javascript">
</script>
<script src="#Url.Content("~/Scripts/jquery-ui-1.8.24.js")" type="text/javascript">
</script>
<script src="#Url.Content("~/Scripts/jquery.validate.js")" type="text/javascript">
</script>
<script src="#Url.Content("~/Scripts/jquery.validate.unobtrusive.js")" type="text/javascript">
</script>
<script src="#Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript">
</script>
and also include the below css link in _Layout.cshtml for a stylish popup.
<link rel="stylesheet" type="text/css" href="../../Content/themes/base/jquery-ui.css" />
I had a similar problem and in my case, the issue was different (I am using Django templates).
The order of JS was incorrect (I know that's the first thing you check but I was almost sure that that was not the case, but it was). The js calling the dialog was called before jqueryUI library was called.
I am using Django, so was inheriting a template and using {{super.block}} to inherit code from the block as well to the template. I had to move {{super.block}} at the end of the block which solved the issue. The js calling the dialog was declared in the Media class in Django's admin.py. I spent more than an hour to figure it out. Hope this helps someone.
I am using jQuery a lot, but sometimes I get stuck because my browser cannot see the jQuery library, or maybe loads the library after running the my JavaScript code.
Pseudo-code to explain my question:
<html>
<head>
I always load CSS here
I always load jquery here
</head>
<body>
<p class="link-style3"><span id="my_tag"><span>Bize Hemen Yazın</span></span></p>
<script>
$(function() {
$('#my_tag').click(function(e) {
alert('tesrt');
});
});
</script>
</body>
</html>
I always put my stuff in the order like below, but this doesn't work now. When I click the <span id="my_tag">, it doesn't do anything, and doesn't return any error.
what should I do?
Here is the entire code jsfiddle
Try to avoid some syntax errors like(suggestable only)
<script type="text/javascript">
$(function() {
$('#my_tag').click(function() {
alert('tesrt');
});
})
</script>
and put your code at the top after you load the js files
A few things you can do:
inspect your document (network pane in devtools) to see if everything
is loading correctly
Move your scripts to the bottom of the page
use $(document).ready(function(){ ... });
