Why is a MarionetteJS module gets undefined jQuery? - marionette

I have the following code:
app.js
var AgencyUI = new Marionette.Application();
AgencyUI.addRegions({
gridRegion: "#gridRegion"
});
AgencyUI.on("initialize:after", function() {
AgencyUI.trigger("grid:loadGrid");
});
grid_app.js
AgencyUI.module('GridApp', function(GridApp, AgencyUI, Backbone, Marionette, $, _) {
var API = {
loadGrid: function(dateRange) {
GridApp.Show.Controller.loadGrid(dateRange);
}
};
AgencyUI.on("grid:loadGrid", function(dateRange) {
API.loadGrid(dateRange);
});
});
show_controller.js
AgencyUI.module('GridApp.Show', function(Show, AgencyUI, Backbone, Marionette, $, _) {
Show.Controller = {
loadGrid: function(dateRange) {
// undefined
console.log($);
}
};
});
Why is jQuery ($) undefined?

The most obvious guess: jQuery simply hasn't loaded yet. Perhaps the script references are added in the wrong order or this particular code is executed before jQuery has been loaded.

how to integrate google-recaptcha in oracle-jet

I am trying to integrate google-recaptcha but no success.

Do you have a mapping for 'googlerecaptcha' in src/js/path_mapping.json? If I go to https://www.google.com/recaptcha/api.js?onload=onloadCallback&render=explicit, I do not see that it is returning any valid object. So most likely 'grecaptcha' variable is undefined.
reCaptcha + RequireJS
Looks like reCaptcha is a function that has to be executed vs an object that can be interacted with directly. So you may need a different approach, something mentioned in this thread.

react-flux application error - unable to find the function even if it's defined

I have a react component - coursePage.js
function getCourseInitState(){
return {
courses: CourseStore.getAllCourses()//courseStore is required in script
};
}
var Courses = React.createClass({
getInitialState: function(){
return getCourseInitState();
},
render: function () {
return (
<div>
<h1> Course </h1>
<CourseList courses={this.state.courses} />
</div>
);
}
});
Action file -courseAction
var CourseAction = {
CourseList: function(){
var courseList = CourseApi.getAllCourses();
Dispatcher.dispatch({
actionType: ActionTypes.COURSE_INITIALIZE,
courseList: courseList
});
}
Store File - courseStore
var CourseStore = assign({}, EventEmitter.prototype, {
addChangeListener: function(callback){
this.on(CHANGE_EVENT, callback);
},
removeChangeListener: function(callback){
this.removeListener(CHANGE_EVENT, callback);
},
emitChange: function(){
this.emit(CHANGE_EVENT);
},
getAllcourses: function(){ //here is the function define
return _courses;
},
getCourseById: function(id){
return _.find(_courses, {id: id});
}
});
Dispatcher.register(function(action){
switch(action.actionType){
case ActionTypes.COURSE_INITIALIZE:
_courses = action.CourseList;
CourseStore.emitChange();
break;
}
});
module.exports = CourseStore;
in console I am getting "Uncaught TypeError: CourseStore.getAllCourses is not a function"
I don't want to call api directly in my coursePage.js so I find this way of initialising the page but it is not working.
(Please note - I am new to this) As per my recent learning Action file must always call API and send the request to State. I can load with help of componentWillMount function. But, I wanted to solve with this.If not wrong, then it is more neat and preferable way of implementing?
You have a typo -> getAllcourses in the Store and in the Component you call getAllCourses
getAllCourses: function(){ //Should be getAllCourses instead of getAllcourses
return _courses;
},

Jasmine calling function with ajax returned value

I want to test the "addGroup" function using Jasmine. I get the following error:
Error: Expected spy modifyMyHtml to have been called.at null.
I don't know what is the best way to test the addGroup function. Please HELP.....
var myRecord = {
addGroup: function(groupNumber) {
$.when(myRecord.getHtml())
.done(function(returnedHtml){
myRecord.modifyMyHtml(returnedHtml);
});
},
getHtml: function() {
return $.ajax({url: "myHtmlFile.html", dataType: "html" });
},
// adds options and events to my returned HTML
modifyMyHtml: function(returnedHtml) {
$('#outerDiv').html(returnedHtml);
var myOptions = myRecord.getOptions();
$('#optionsField').append(myOptions);
myRecord.bindEventsToDiv();
},
}
====JASMINE TEST
describe("Configure Record page", function() {
var fixture;
jasmine.getFixtures().fixturesPath = "/test/" ;
jasmine.getFixtures().load("myHtmlFile.html");
fixture = $("#jasmine-fixtures").html();
describe("addGroup", function(){
beforeEach(function() {
var groupNumber = 0;
spyOn(myRecord, "getHtml").andCallFake(function(){
return $.Deferred().promise();
});
spyOn(myRecord, "modifyMyHtml");
myRecord.addGroup(groupNumber);
});
it("Should call getHtml", function() {
expect(myRecord.getHtml).toHaveBeenCalled();
});
it("Should call modifyMyHtml", function() {
expect(myRecord.modifyMyHtml).toHaveBeenCalled(); ==>FAILS
});
});
});
You have to resolve the promise before you return em in your andCallFake.
spyOn(myRecord, "getHtml").andCallFake(function(){
return $.Deferred().resolve ().promise();
});
Btw. you should not test that the function on the object you wanna test are called, but that the html in the DOM are set with the right html
it("Should call modifyMyHtml", function() {
spyOn(myRecord, "getHtml").andCallFake(function(){
return $.Deferred().resolveWith(null, 'returnedHtml').promise();
});
expect($('#outerDiv').html).toEqual('returnedHtml')
});

backbone console log event triggering

I've got a underscore/backbone/require application and I would like to output all events that are triggered through backbone to the console (in other words: pass each event through console.log function). I've tried wrapping it with underscore and manually replacing the function. Neither this:
console.log(Backbone.Events.trigger);
var trigger = Backbone.Events.trigger;
Backbone.Events.trigger = function(name) {
console.log('Event', name, 'triggered.');
trigger.apply(this, arguments);
}
nor this:
Backbone.Events.trigger = _.wrap(Backbone.Events.trigger, function(func) {
console.log('EVENT:', Array.prototype.slice.call(arguments));
func(Array.prototype.slice.call(arguments));
});
console.log(Backbone.Events.trigger);
worked. I'd appreciate a javascript (not coffeescript) solution.
Your wrappings fail because Backbone mixes in Backbone.Events behavior on Backbone.Model, Backbone.Collection, etc. For example, Backbone.Model is defined as
var Model = Backbone.Model = function(attributes, options) {
...
};
_.extend(Model.prototype, Events, {
...
};
This means that when you redefine Backbone.Events.trigger, it is already too late.
But all is not lost! You won't be able to redefine all trigger methods in one go, but you can redefine them on class level:
Backbone.Model.prototype.trigger = function() {
console.log('Event', arguments);
Backbone.Events.trigger.apply(this, arguments);
}
and a demo http://jsfiddle.net/nikoshr/G2Qfn/
For a given class, you can override the trigger method:
var M = Backbone.Model.extend({
trigger: function() {
console.log('Event', arguments);
Backbone.Model.prototype.trigger.apply(this, arguments);
}
});
http://jsfiddle.net/nikoshr/G2Qfn/1/
or for a given instance
var M = Backbone.Model.extend({});
var m = new M();
m.trigger = function() {
console.log('Event', arguments);
M.prototype.trigger.apply(this, arguments);
}

subpage loaded through ajax is killing jquery functionality

I'm working on a site, http://teneo.telegraphbranding.com/, and I am hoping to load the pages via ajax so that the sidebar and its animation remain consistent.
When the 'About' link is clicked I need it to load about2.php via a jquery ajax function. But I'm not having any luck. When I can get the page to load via ajax it kills all the jquery functionality on the page. From what I've read I think I need to call the jquery upon successful completion of the ajax call.
I've tried everything it seems and can't get it work. What I need is about2.php to load when the link is clicked and the jquery to dynamically size the divs, like it does on the homepage.
I tried this, but it won't even load the page:
//Dropdown
$(document).ready(function () {
var dropDown = $('.dropdown');
$('h3.about').on('click', function() {
dropDown.slideDown('fast', function() {
var url = 'about2.php'
$.get(url, function(data) {
//anything in this block runs after the ajax call
var missionWrap = $('#mission-wrap');
var w = $(window);
w.on('load resize',function() {
missionWrap.css({ width:w.width(), height:w.height()});
});
var missionContent = $('#mission-content');
var w = $(window);
w.on('load resize',function() {
missionContent.css({ width:w.width() - 205 });
});
});
});
});
});
And then this loads the page, but kills all the jQuery associated with it:
var dropDown = $('.dropdown');
$('h3.about').on('click', function() {
dropDown.slideDown('fast', function() {
$('#index-wrap').load('/about2.php');
});
});
Thank you very much.
I also tried this and it just broke everything:
$(document).ready(function () {
var dropDown = $('.dropdown');
$('h3.about').on('click', function () {
dropDown.slideDown('fast', function () {
$.ajax({
type: 'GET',
url: 'about2.php',
success: function () {
var missionWrap = $('#mission-wrap');
var w = $(window);
w.on('load resize', function () {
missionWrap.css({
width: w.width(),
height: w.height()
});
});
var missionContent = $('#mission-content');
var w = $(window);
w.on('load resize', function () {
missionContent.css({
width: w.width() - 205
});
});
};
});
});
});
});
This should work.
function resize_me () {
var w = $(window);
var missionWrap = $('#mission-wrap');
var missionContent = $('#mission-content');
missionWrap.css({ width:w.width(), height:w.height()});
missionContent.css({ width:w.width() - 205 });
}
//Dropdown
$(document).ready(function () {
$(window).on('load resize', function () {
resize_me();
});
var dropDown = $('.dropdown');
$('h3.about').on('click', function() {
dropDown.slideDown('fast', function() {
var url = 'about2.php'
$.get(url, function(data) {
resize_me();
});
});
});
}
I believe that the problem was that the load event that you were attaching to the window object was not being triggered by the successful load of the $.get.
This is a rough outline of how to structure your application to handle this correctly.
Assuming your HTML looks something like this:
<html>
...
<div id="index-wrap">
<!-- this is the reloadable part -->
...
</div>
...
</html>
You need to refactor all the jQuery enhancements to the elements inside #index-wrap to be in a function you can call after a reload:
function enhance(root) {
$('#some-button-or-whatever', root).on('click', ...);
}
(I.e. look up all the elements under the root element that was loaded using AJAX.)
You need to call this function when the page is first loaded, as well as after the AJAX call in the completion callback:
$('#index-wrap').load('/foo.php', function() {
enhance(this);
});
You can also potentially get rid of some of this using delegated ("live") events, but it's best to hit the jQuery documentation on how those work.
As for events bound to window or DOM elements which aren't loaded dynamically, you shouldn't need to rebind them at all based on which subpage is loaded, just check which of your elements loaded is in a handler that you set up once:
$(window).on('load resize', function() {
var $missionContent = $('#missionContent');
if ($missionContent.length) {
$missionContent.css(...);
}
});
