I am adding jquery using requireJS like
requirejs.config({
enforceDefine: true,
paths: {
jquery: 'http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min'
}
});
Later in seperate JS file I am loading on page using require as
require(['jquery'], function ($) {
//Do something with $ here
}, function (err) {});
I gave jquery URL incorrectly and want to show some custom err message to end user..I added above code but when URL is incorrect the control is not coming inside err function..Do I want to add any other code..I am using for DOJO version.
It seems you're using the Dojo AMD loader, they have a different approach of handling errors.
While in RequireJS you would use:
require([ 'jquery' ], function($) {
// Do something with $ here
}, function(err) {
// Error handling
});
In Dojo you would use a different syntax, for example:
require.on('error', function(err) {
// Error handling
});
require([ 'jquery' ], function($) {
// Do something with $ here
});
An example: http://plnkr.co/edit/t3j7mTgLKSiTCIrvl2eD?p=preview
However, since you're using Dojo, the requirejs.config() does probably not work either if you're working the Dojo AMD loader.

I was trying to use jquery ui in a sharepoint project and since the jquery is already loaded I don't see the reason of requiring it again when I need the accordion from jquery ui.
I already followed all the steps and added the folders to work with require js. as in:
https://learn.jquery.com/jquery-ui/environments/amd/
but I still get the same error:
Script error for "jquery", needed by: jqueryui/widgets/accordion, jqueryui/version, jqueryui/keycode, jqueryui/unique-id, jqueryui/widget
here is my code:
function main() {
require({
paths: {
jqueryui: '/teams/sp-test-site/dist/jQuery/ui/1.12.1',
},
shim: {
deps: [ 'jquery', ],
},
}, [ 'jqueryui/widgets/accordion', ],
function (accordion) {
$('#accordion').accordion();
});
}
ExecuteOrDelayUntilScriptLoaded(function () {
SP.SOD.executeFunc('require.js', null, main);
}, 'core.js');
So I assume I am missing some init function to use the already loaded jquery from the globals, I am just not sure how, if it is the case. Does any body know what could be wrong here?
defining jquery and returning the global one solved.
define('jquery', [], function () {
return window.jQuery;
});
I'm upgrading from jQuery 1.8 to 1.9 and since jQuery.browser() is removed, I will use jQuery Browser Plugin.
My requirejs config file (loaded using data-main="") looks somewhat like this:
(EDITED - added more code snippets)
main-comp.js
require.config({
paths: {
jquery: 'libs/jquery/jquery1.9.1.min',
utils: 'modules/utils',
myController: "controllers/myController",
browserPlugin: 'libs/jquery/jquery.browser.min'
},
shim: {
browserPlugin: {
deps: ['jquery']
}
}
});
require(['myController', 'jquery'], function (controller, $) {
$(controller.start);
}
);
moduls/utils.js
define(['browserPlugin'], function () {
return {
browser: $.browser
};
});
myController.js
define(['utils'], function (utils) {
function start() {
console.log(utils.browser.msie)
}
return {
start: start
};
});
Everything seemed to work properly, but then I saw that sometimes in IE only I get a 'jQuery' is undefined (it's a capital Q there) or '$' is undefined errors from the jquery.browser.min.js file.
I thought the deps means that jquery will load before the jquery.browser file but apparently this isn't always the case. I tried following this answer and add exports: "$.fn.browser" but with no success.
When running an optimized version (minify+uglify using r.js) I haven't encountered it.
What am I doing wrong?
You need to ensure you reference $ as a parameter in the require callback. Like so:
require(['myController', 'jquery'], function (controller, $) {
$(controller.start);
}
);
This ensures that jQuery is available to use. It is a bit of an odd one as it will expose itself globally anyway so it will sometimes work regardless, but the correct way is to explicitly require it and use it inside the callback as a parameter.
It looks like you are missing jquery dependency in moduls/utils.js, please try:
define(['jquery', 'browserPlugin'], function ($) {
return {
browser: $.browser
};
});
and also, just to be on the safe side, add jquery to your shim :
jquery: {
exports: "$"
},
By the way, why don't you use $.browser in your code and just load the jquery plugin using the shim configuration?
I had the same problem, the script in data-main is loading asynchronously, that means that it may load after the scripts it defines.
The solution is to load another script with the require.config right after the require.js script.

I'm trying to load jqplot as a requireJS module.
My main.js has a path and shim like this:
require.config({
, paths: {
plot: '../js/plugins/jqplot/jqplot.module'
}
, shim: {
'plot': { deps: ['jquery']}
}
});
Since this module is not needed on most pages, I'm waiting for the pageXYZ to be loaded and then inside a <script></script>, I'm calling:
require(['plot'],
function (plot) {
// do stuff
}
);
And my jqplot.module looks like this:
define(['../js/plugins/jqplot/jquery.jqplot'],
function () {
require([
'../js/plugins/jqplot/plugins/jqplot.barRenderer'
, '../js/plugins/jqplot/plugins/jqplot.logAxisRenderer'
, '../js/plugins/jqplot/plugins/jqplot.categoryAxisRenderer'
, '../js/plugins/jqplot/plugins/jqplot.canvasAxisTickRenderer'
, '../js/plugins/jqplot/plugins/jqplot.canvasTextRenderer'
, '../js/plugins/jqplot/plugins/jqplot.pointLabels'
, '../js/plugins/jqplot/plugins/jqplot.enhancedLegendRenderer'
],
function (){
return $.jqplot;
}
);
}
);
which returns the correct object with all sub-plugins defined and usable.
However, my Do stuff code runs BEFORE jqplot is assigned to $, so I'm still getting undefined errors when my code runs (I assume, because the files are all loaded, so requirejs starts running)
Question:
What can I do halt code execution until the jqplot has been assigned to $?
1) I think this line from your question:
define(['../js/plugins/jqplot/jquery.jqplot'],
should read:
define(['../js/plugins/jqplot/jquery.module'],
2) You do not need a shim, because you have a module definition that loads jqplot. So change your requirejs.config to
require.config({
, paths: {
plot: '../js/plugins/jqplot/jqplot.module'
}
});
3) your jqplot.module is not returning anything right now. Change it to:
define([
'../js/plugins/jqplot/jquery.jqplot'
],
function () {
var plot;
require([
'../js/plugins/jqplot/plugins/jqplot.barRenderer',
'../js/plugins/jqplot/plugins/jqplot.logAxisRenderer',
'../js/plugins/jqplot/plugins/jqplot.categoryAxisRenderer',
'../js/plugins/jqplot/plugins/jqplot.canvasAxisTickRenderer',
'../js/plugins/jqplot/plugins/jqplot.canvasTextRenderer',
'../js/plugins/jqplot/plugins/jqplot.pointLabels',
'../js/plugins/jqplot/plugins/jqplot.enhancedLegendRenderer'
],
function () {
plot = $.jqplot;
});
return plot;
});
This is all untested, but I think these should help
Answering this question and all the repeats, basic above answer is close but no cigar, as require is async, as such require could/will fire before define closure closes and returns, async safe solution below :
Nasty problem, as it's a chain of three dependencies
jquery is required for jqplot which is required for jqplot plugins, I have a simpler solution based on the same lines as the one above
first do your requirejs "main.js" config like so
requirejs.config({
paths: {
"jquery": "path/to/jquery-1.10.2.min",
// WORKAROUND : jQuery plugins + shims
"jqplot.core": "path/to/jquery-jqplot-1.0.8.min",
"jqplot": "jquery-jqplot-module-with-plugins-1.0.8"
},
shim: {
"jqplot.core": {deps: ["jquery"]},
"jqplot": {deps: ["jqplot.core"]}
}
});
create a wrapper file module file called "jquery-jqplot-module-with-plugins-1.0.8.js", containing :
// wraps jquery jqplot plugin in define statement
define([
"jquery",
"path/to/jqplot.highlighter.min",
"path/to/jqplot.cursor.min",
"path/to/jqplot.dateAxisRenderer.min",
"path/to/jqplot.canvasTextRenderer.min",
"path/to/jqplot.canvasAxisLabelRenderer.min",
"path/to/jqplot.enhancedLegendRenderer.min",
"path/to/jqplot.pieRenderer.min",
"path/to/jqplot.donutRenderer.min",
], function($) {
var jqplot;
jqplot = $.jqplot;
return jqplot;
});
Then when ever you need jqplot with those plugins, simply call for "jqplot" which will load "jquery" then "jqplot.core" then all the jqplot modules, then finally return the jqplot object :)
require(["jquery", "jqplot"], function ($, $jqplot) {
console.log("Success..Inside Require JS");
console.log("Plot...", $.jqplot, $jqplot);
});
or
define(["jquery", "jqplot"], function ($, $jqplot) {
console.log("Success..Inside Define JS");
console.log("Plot...", $.jqplot, $jqplot);
});
tada! :)
ps jquery plugins are evil, no suggestion how to fix that situation, just a statement of fact
cheers

I am totally new to RequireJS so I'm still trying to find my way around it. I had a project that was working perfectly fine, then I decided to use RequireJS so I messed it up :)
With that out of the way, I have a few questions about RequireJS and how it figures out everything. I have the file hierarchy inside the scripts folder:
I have the following line inside my _Layout.cshtml file:
<script data-main="#Url.Content("~/Scripts/bootstrap.js")" src="#Url.Content("~/Scripts/require-2.0.6.js")" type="text/javascript"></script>
And here's my bootstrap.js file:
require.config({
shim: {
'jQuery': {
exports: 'jQuery'
},
'Knockout': {
exports: 'ko'
},
'Sammy': {
exports: 'Sammy'
},
'MD': {
exports: 'MD'
}
},
paths: {
'jQuery': 'jquery-1.8.1.min.js',
'Knockout': 'knockout-2.1.0.js',
'Sammy': 'sammy/sammy.js',
'MD': 'metro/md.core.js',
'pubsub': 'utils/jquery.pubsub.js',
'waitHandle': 'utils/bsynchro.jquery.utils.js',
'viewModelBase': 'app/metro.core.js',
'bindingHandlers': 'app/bindingHandlers.js',
'groupingViewModel': 'app/grouping-page.js',
'pagingViewModel': 'app/paging-page.js'
}
});
require(['viewModelBase', 'bindingHandlers', 'Knockout', 'jQuery', 'waitHandle', 'MD'], function (ViewModelBase, BindingHandlers, ko, $, waitHandle, MD) {
BindingHandlers.init();
$(window).resize(function () {
waitHandle.waitForFinalEvent(function () {
MD.UI.recalculateAll();
}, 500, "WINDOW_RESIZING");
});
var viewModelBase = Object.create(ViewModelBase);
ko.applyBindings(viewModelBase);
viewModelBase.initialize();
});
require(['viewModelBase', 'bindingHandlers', 'Knockout'], function (ViewModelBase, BindingHandlers, ko) {
BindingHandlers.init();
var viewModelBase = new ViewModelBase();
ko.applyBindings(viewModelBase);
viewModelBase.initialize();
});
Then I implemented my modules by using the define function. An example is the pubsub module:
define(['jQuery'], function ($) {
var
publish = function(eventName) {
//implementation
},
subscribe = function(eventName, fn) {
//implementation
}
return {
publish: publish,
subscribe: subscribe
}
});
I've basically done the same thing to all of my javascript files. Note that the actual file containing the pubsub module is jquery.pubsub.js inside the /Scripts/utils folder. This is also the case with other modules as well.
UPDATE:
Ok I updated my bootstrap file now that I think I understand what a shim is and why I should be using it. But it's still not working for me, although I've also declared all the paths that I think would've caused me trouble in getting them right. The thing is that it's not even going into my require callback inside the bootstrap file, so I guess I still have a problem in the way I'm configuring or defining my modules?
Well, for one, if you are going to use a non-amd library, say jQuery, with require and have the jQuery function passed to the callback, you need to specify a shim with exports in your require config, like so:
require.config({
shim: {
jQuery: {
exports: '$'
}
},
paths: {
jQuery: 'jquery-1.8.1.min.js',
}
});
Other than that I'm not sure I understand what your issue is exactly.
If you are using ASP.NET MVC take a look at RequireJS for .NET
The RequireJS for .NET project smoothly integrates the RequireJS framework with ASP.NET MVC on the server side using xml configuration files, action filter attributes, a base controller for inheritance and helper classes.
I did not completely understand what the problem is. But if it relates to JS libraries to be loaded with require.js then this boot file works for me:
require.config({
paths: {
"jquery": "/scripts/jquery-1.8.2",
"sammy": "/scripts/sammy-0.7.1"
},
shim: {
"sammy": {
deps: ["jquery"],
exports: "Sammy"
}
}
});
require(["jquery", "sammy"], function ($) {
$(document).ready(function () {
alert("DOM ready");
});
});
Please, note, there is no '.js' in paths.
BTW, if you use MVC 4, you don't need #Url.Content in 'href' and 'src' any more.
I have about 3 different errors that can occur while loading the same page. I get different errors when I refresh the same page: jquery ui loads before jquery, or underscore does not load in time to be a dependency. Is there a way to make sure the configuration modules wait until their depenedencies load before loading themselves? I am using the following:
main.js
require.config({
paths: {
jQuery: 'libs/jquery/jquery-wrapper',
Underscore: 'libs/underscore/underscore-wrapper',
Backbone: 'libs/backbone/backbone-wrapper',
}
});
require([
'src/app',
'order!libs/jquery/jquery-min',
'order!libs/jquery/jquery-ui-min',
'order!libs/jquery/jquery.ui.selectmenu',
'order!libs/underscore/underscore-min',
'order!libs/backbone/backbone-min',
], function (App) {
App.initialize();
});
I grab injected dependencies from the page.
app.js
define([
'jQuery',
'src/global'
], function ($) {
var initialize = function () {
var d = $('#dependencies').html();
require($.trim($('#dependencies').html().toString()).split(','), function () {
});
}
return {
initialize: initialize
};
});
I was using Require v2, which got rid of order. I switched back to version 1 and the problem was resolved.
I switched to Require 2.0 and employed a shim that is working for the most part.
