I'm using the jQuery UI Layout plugin and I keep getting this error in Firebug: $('body').layout is not a function. I also get the same error in IE8 and below.
Obviously, it's being caused by the line where I initiate the layout UI in my scripts file:
$('body').layout({ *options here* });
Is there a way to prevent this error from showing? I'm pretty sure I need the BODY selector for this particular plugin to run.
** SOLUTION **
As the helpful answers say below, I had this line: $('body').layout({ *options here* }); BEFORE I included my jQuery and jQuery UI Layout Plugin files. Once I put the body.layout after those two inclusions, the error went away.
You seem to either
1) have not included the plugin properly (script tag missing/typo in the url, included it before loading jquery itself, whatever else could go wrong)
or
2) calling $("body").layout too early - wrap it with $(document).ready(function() { });
it should be
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript" src="jquery.layout.js"></script>
...
<script type="text/javascript">
$(document).ready(function() {
$("body").layout() // will work now
});
</script>
Make sure you're including the lines:
<SCRIPT type="text/javascript" src="/path/to/jquery-latest.js"></SCRIPT>
<SCRIPT type="text/javascript" src="/path/to/jquery.layout-latest.js"></SCRIPT>
Prior to the code you placed in your question. Otherwise, layout will have been undefined before use.

I have my jQuery linked in the html file before the js file, and I've ensured that it is loading properly in the browser window. The jQuery code actually WORKS, so I have no idea why sublime thinks it cant understand the sytax. I've tried just about every suggestion in this post (JQuery - $ is not defined) which there was a ton. Also, i dont currently have sublimeLinter installed, currently using a console that i set up with this (http://www.wikihow.com/Create-a-Javascript-Console-in-Sublime-Text).
This code:
<html>
<head>
<script type="text/javascript" src="jquery-3.2.1.min.js"></script>
<script type="text/javascript" src="script.js"></script>
</head>
<body> </body>
</html>
with this js:
var $j = jQuery.noConflict();
$j(document).ready(function() {
$j("body").text("Hello world!");
});
leads to this error message:
Add an ignore comment to the top of your document. What is happening is that your linter is not seeing jQuery as it is not part of the current document. This will force your linter to ignore the jQuery keyword while linting.
/*globals $:false, jQuery:false*/
I'm new to web development, and was having issues with two plug-ins. I already found a workaround to solve it, but I'm not convinced at all about what I did, so I ask you guys if you can enlighten me on what is this about.
The page in question uses SlimScroll and DataTables plugins. At first, I had an HTML file like this one.
<body>
<!-- STUFF -->
<!-- SCRIPTS -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.2/jquery.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.11.4/jquery-ui.min.js"></script>
<script src="plugins/bootstrap/js/bootstrap.min.js" type="text/javascript"></script>
<script src="plugins/slimScroll/jquery.slimscroll.min.js" type="text/javascript"></script>
<script src="plugins/DataTables/datatables.min.js" type="text/javascript"></script>
<script src="assets/scripts/tablas.js" type="text/javascript"></script>
<script src="assets/scripts/general.js" type="text/javascript"></script>
At the bottom, general.js is used to handle click events and other stuff, and tablas.js has the code that picks up a file with data and displays it in DataTables. The relevant code from general.js:
$(document).ready(function() {
$('#contenedor-menu').slimScroll({
height: '100%'
});});
And the code for tablas.js:
$(document).ready(function() {
$('#tablita').DataTable( {
"ajax": 'data/COut2.txt',
} );});
With this structure, when I load the page, SlimScroll fails with the message in the console: "TypeError: $(...).slimScroll is not a function"
Then after touching around, I switched the order of the scripts in the HTML file. I put datatables first and then slimscroll.
<script src="plugins/DataTables/datatables.min.js" type="text/javascript"></script>
<script src="plugins/slimScroll/jquery.slimscroll.min.js" type="text/javascript"></script>
And now it works ok, with no errors.
Could somebody please explain to me what's going on?
Thanks in advance!
The use of multiple $(document).ready(function() { } is the main cause of this issue. There should be only one Document Ready event handler.
You may try using the pageLoad() function or onLoad() events
Not positive but it is usually best practice to put the scripts you absolutely need before everything else in the head. This is so that the content of the page does not finish loading until all the dependencies have been loaded first.
By reordering your scripts you may have a solution that will only work some of the time.
Put all the scripts you need to load in the head and your general.js script at the end of your body element.
I'm trying to get a functional lightbox to work on my page using code from 'bootply.com/' but it does't seem to work. It works as a link, but not as a lightbox. I get an error relating to the Javascript which states '$ is not defined', but I can't seem to locate the issue. I'm simply replicating the code, so not sure what I'm missing!
<script type="text/JavaScript">
$('.thumbnail').click(function(){
$('.modal-body').empty();
var title = $(this).parent('a').attr("title");
$('.modal-title').html(title);
$($(this).parents('div').html()).appendTo('.modal-body');
$('#myModal').modal({show:true});
});

Any help is appreciated.
you have to include jQuery.
if you have jQuery lib then
<script src="jquery-1.11.2.min.js"></script>
or
use jQuery CDN
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
You are missing the jQuery library..
Include this in the top of your HTML before you attempt to use the $
<script src="https://code.jquery.com/jquery-2.1.3.min.js"></script>
Alternatively you can download the jQuery library and reference it yourself.
This should resolve the issue.
I haven't used jQuery before, and I wanted to use DateTimePicker plugin on my web page.
I downloaded the plugin file and placed them in the same directory as the HTML files.
I directly applied the code at How to use it? in http://xdsoft.net/jqplugins/datetimepicker/.
It threw the following error.
Uncaught TypeError: undefined is not a function pixelcrawler:61 (anonymous function)
My code follows.
<script type='text/javascript' src="//ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<link rel="stylesheet" type="text/css" href="file:///jquery.datetimepicker.css"/ >
<script src="file:///jquery.datetimepicker.js"></script>
<script>
jQuery('#datetimepicker').datetimepicker();
</script>
<div class="container">
<div class="text-center">
<div class="page-header">
<h1>${conf['title']} <small>${conf['description']}</small></h1>
</div>
</div>
<div class="text">
<input id="datetimepicker" type="text" >
.
.
.
.
.
I could not figure out what the problem was. I have tried many other seemingly likely options, but it just did not work either.
(The ${} tags are used for the Mako template language. I am using Cherrypy.)
UPDATE:
I figured out the source of the problem.
It's from jQuery('#datetimepicker').datetimepicker();.
When tested, the datetimepicker() function was undefined. Maybe the way I imported the library was wrong?
jQuery(document).ready(function(){
jQuery('#datetimepicker').datepicker();
})
I don't know your file-structure. I never include local files like this as I use relative URLs from the start rather than having to change everytime I'm ready to use the code, but it's likely one of the files isn't being loaded in. I've included the standard datepicker below using Google CDN's jQuery UI. Does your console log any resources not found?
I think your jQuery is loaded OK, because it's not telling you jQuery is not defined so it's one of your files.
BTW, PHP gets the home URL:
$home="http://" . $_SERVER['HTTP_HOST'].'/';
Demo code datepicker, jQuery UI:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<link rel="stylesheet" href="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.4/themes/smoothness/jquery-ui.css" />
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.4/jquery-ui.min.js"></script>
<script type="text/javascript">
jQuery(document).ready(function(){
jQuery('#datetimepicker').datepicker();
})
</script>
<input id="datetimepicker" type="text">
This is about the HTML parse mechanism.
The HTML parser will parse the HTML content from top to bottom. In your script logic,
jQuery('#datetimepicker')
will return an empty instance because the element has not loaded yet.
You can use
$(function(){ your code here });
or
$(document).ready(function(){ your code here });
to parse HTML element firstly, and then do your own script logics.
use jQuery.noConflict()
var j = jQuery.noConflict();
j(document).ready(function(){
j('#datetimepicker').datepicker();
})
For my situation, it was a naming conflict problem. Adding $J solves it.
//Old code:
function () {
var extractionDialog;
extractionDialog = $j("#extractWindowDialog").dialog({
autoOpen: false,
appendTo: "form",
height: "100",
width: "250",
modal: true
});
$("extractBomInfoBtn").button().on("click", function () {
extractionDialog.dialog("open");
}
And the following is new code.
$j(function () {
var extractionDialog;
extractionDialog = $j("#extractWindowDialog").dialog({
autoOpen: false,
appendTo: "form",
height: "100",
width: "250",
modal: true
});
$j("extractBomInfoBtn").button().on("click", function () {
extractionDialog.dialog("open");
});
});
Hope it could help someone.
Usually when you get this problem, it happens because a script is trying to reference an element that doesn't exist yet while the page is loading.
As richie mentioned: "The HTML parser will parse the HTML content from top to bottom..."
So you can add your JavaScript references to the bottom of the HTML file. This will not only improve performance; it will also ensure that all elements referenced in your script files have already been loaded by the HTML parser.
So you could have something like this:
<html>
<head>
<!-- Style sheet references and CSS definitions -->
</head>
<body>
<!-- HTML markup and other page content -->
<!-- JavaScript references. You could include jQuery here as well and do all your scripting here. -->
</body>
</html>
You may see if you are not loading jQuery twice somehow. Especially after your plugin JavaScript file loaded.
I has the same error and found that one of my external PHP files was loading jQuery again.
The issue because of not loading jquery ui library.
https://code.jquery.com/ui/1.11.4/jquery-ui.js - CDN source file
Call above path in your file.
And if you have this problem in slider or slideshow you must use jquery.easing.1.3:
<script src="http://gsgd.co.uk/sandbox/jquery/easing/jquery.easing.1.3.js"></script>
I had trouble getting selectable to work with ASP.NET. It turns out I wasn't properly including everything, but this gentleman made it foolproof: Three steps to use jQuery UI in ASP.NET MVC 5.
I don't think jQuery itself includes datetimepicker. You must use jQuery UI instead (src="jquery.ui").
I'm trying to use the jquery tokeninput plugin, the demos work fine however when I try to implement it I'm hitting a brick wall. Chrome chucks this at me:
Uncaught TypeError: Object [object Object] has no method 'tokenInput'
Below is an excerpt from my <head>, chrome's resource browser shows both jQuery and jquery.tokeninput are loaded fine. No URL issues.
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"></script>
<script type="text/javascript" src="/media/js/jquery.tokeninput.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$("#token").tokenInput("/members/api/members/tokeninput_members/?format=json");
});
</script>
And showing that tokeninput has loaded:
Right, bare-bones page worked fine. After digging a while longer I found this buried at the base of the page:
<script src="http://code.jquery.com/jquery.js"></script>
It seems having multiple versions of jQuery loaded is not a good thing to do.
I am not sure if you already solved it or not. But Try this it should work if your sequence of jquery library inclusion is right (which it seems right), also remove one of jquery.min.js, jquery.js.
Then try this
<script type="text/javascript">
// Any valid variable name is fine.
var j = jQuery.noConflict();
j(document).ready(function () {
j("#token").tokenInput("/members/api/members/tokeninput_members/?format=json");
});
</script>
