I'm not sure if there has been a change in the way Meteor loads items, or the way it handles jquery, but I'm having an awful lot of trouble getting ckeditor to come up.
Main Template (Iron-router):
<template name="layout">
<head>
<script type="text/javascript" src="js/ckeditor/ckeditor.js"></script>
<script type="text/javascript" src="js/ckeditor/adapters/jquery.js"></script>
</head>
.....
</template>
Independent Editor Template:
<template name="editor">
<div class="editor_container">
<textarea class="editor"></textarea>
</div>
</template>
Ckeditor located at public/js/ckeditor, any time I try to do the Template.editor.rendered() technique, or even just trying to type $('.editor').ckeditor(); into the console, I get an error of:
$('.editor').ckeditor();
VM48825:2 Uncaught TypeError: undefined is not a function
Any ideas?
Try taking the <head> section out of the layout template. Reading here I believe the <head> section is treated specially be meteor (see: http://docs.meteor.com/#/full/structuringyourapp) and that it being inside a template may be causing the JS to actually not be loaded. Just a guess though.
<head>
<script type="text/javascript" src="js/ckeditor/ckeditor.js"></script>
<script type="text/javascript" src="js/ckeditor/adapters/jquery.js"></script>
</head>
<template name="layout">
.....
</template>
You can use IRLibLoader from iron:router into the onBeforeAction like this.
Router.route('/editor', {
name: 'editor',
template: 'layout',
onBeforeAction: function () {
var ckEditor = IRLibLoader.load('/js/ckeditor/ckeditor.js');
var adapter = IRLibLoader.load('/js/ckeditor/adapters/jquery.js');
if(ckEditor.ready() && adapter.ready()){
console.log('The 2 JS just finish load');
this.next(); // Render the editor page
if(Meteor.isClient){
Template.editor.rendered = function(){
$('.editor').ckeditor();
console.log("loading coeditor when template fully rendered");
}
}
}
}
});
Alternative on the main layout you can use this.
<head>
<script type="text/javascript" src="js/ckeditor/ckeditor.js"></script>
<script type="text/javascript" src="js/ckeditor/adapters/jquery.js"></script>
</head>
<template name="layout">
{{> yield}}
</template>
<template name="editor">
<div class="editor_container">
<textarea class="editor"></textarea>
</div>
</template>
And do the same rendered function
Template.editor.rendered = function(){
$('.editor').ckeditor();
//or make a little delay (1sec)
Meteor.setTiemout(function(){
$('.editor').ckeditor();
},100)
}
There are several problems with your code :
You can't put <head> sections inside another template, it must be done outside all templates.
The path to your JS files are broken, you must prepend a slash to them to reference files in the public directory.
Loading scripts in <head> sections is not a good idea because they will be loaded when your app first loads for every user, even if they never use the editor.
Here is a solution where we load every scripts asynchronously using jQuery promises when the editor template is rendered, and only then initialize the CKEditor.
Template.editor.rendered=function(){
var template=this;
$.when(
$.getScript("/js/ckeditor/ckeditor.js"),
$.getScript("/js/ckeditor/adapters/jquery.js")
).done(function(){
template.$(".editor").ckeditor();
});
};

I want to use firebase inside a Vue JS component, but it seems like the firebase object is loaded after the creation of my component.
Is there a way to wait for firebase to load before executing JS code ?
Exemple : i want to create a vue composant called loader which output the firebase object on the webconsole at his creation
<html>
<head>
<!-- Firebase -->
<script defer src="/__/firebase/5.0.4/firebase-app.js"></script>
<!-- include only the Firebase features as you need -->
<script defer src="/__/firebase/5.0.4/firebase-auth.js"></script>
<script defer src="/__/firebase/5.0.4/firebase-database.js"></script>
<script defer src="/__/firebase/5.0.4/firebase-messaging.js"></script>
<script defer src="/__/firebase/5.0.4/firebase-storage.js"></script>
<!-- initialize the SDK after all desired features are loaded -->
<script defer src="/__/firebase/init.js"></script>
<!-- Vue.js-->
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.16/vue.js"></script>
</head>
<body>
<div id="app"></div>
<script>
var loader = {
template: '<div></div>',
created: function(){
console.log(window.firebase); // undefined
}
};
var app = new Vue({
el : '#app',
template :
`<div>
<loader></loader>
</div>`,
components : {
'loader' : loader
}
});
</script>
</body>
</html>
It doesn't work but, of course, one second later i can output the firebase object on the console.
PS :
It is my first question on this website so if you have any advice on how to ask question, i will take it as well.
I am french so pardon my english
You need to remove the defer attributes from the firebase scripts. It will cause the scripts to be executed once the whole document has been parsed, which means that your script in the body runs before firebase scripts.
I'm trying to understand how to modularize the Backbone ToDo tutorial
Originally everything is inside the same file, but if I try to extract to another file:
var TodoView = Backbone.View.extend({
...
});
then this throws an error:
var view = new TodoView({model: todo});
**Uncaught TypeError: undefined is not a function**
It's probably due to a scope issue, but I don't know how to create a reference inside the $(function() so I can create this new object inside the main function.
Assuming that your first code part is TodoView.js,
and your second code part is app.js.
Write your html file like this,
<html>
<head>
<script type="text/javascript" src="js/TodoView.js"></script>
<script type="text/javascript" src="js/app.js"></script>
</head>
<body>
// your dom
</body>
</html>
(Edited, at 2015-07-27)
sorry for my late reply.
how about this?
<html>
<head></head>
<body>
<!-- your dom -->
<script type="text/javascript" src="js/TodoView.js"></script>
<script type="text/javascript" src="js/app.js"></script>
</body>
</html>
In many case, most javascript codes are appended to just before </body>, so that javascript can use your dom!
You can use something like require.js to load your external files and manage dependancies.
Ok, the solution was to move the script references to the end of the body instead of inside the head tags.
I think that the reason is that TodoView.js is making use of templates that were defined in the body, and since the js file was being loaded before the body, the templates were not yet available.
I am working in an ASP.NET MVC project that uses a lot of #section scripts blocks. We also use a lot of partial views. Currently, I have our global JS (global.js) rendered in the <head> element, which blocks the rest of the page from loading until it has finished loading. I want to move this JS into the body, but because my partial views are reliant on the global.js, this becomes a problem. The rendered HTML turns out to be:
<html>
<head>
<title>Page</title>
<!-- Scripts/styles here -->
</head>
<body>
<!-- Partial A -->
<div id="PartialA">Partial A</div>
<script type="text/javascript">
$(function(){
Foo.bar();
});
</script>
<script type="text/javascript" src="global.js"></script>
</body>
</html>
And global.js:
var Foo = {};
Foo.bar = function(){
console.log("I did Foo.bar()!");
}
Is there anything I can do to place my global.js just before the </body tag while still allowing the JS that uses global.js to exist higher up in the body? Maybe some sort of custom "ready" event I can subscribe to?
why not in Partial A
window.initPartialA = function () {
Foo.bar();
}
and in Global
if (window.initPartialA) {
initPartialA();
}
This is really gross, I would figure out a way of how to organize your script tags in asp rather than doing this.
I know its been asked many times, I have looked at the answers and not sure where I am going wrong.
I have looked at the docs on Handlebarsjs and followed a tutorial and both times I am getting the same error.
<!DOCTYPE html>
<html>
<head>
<script src="handlebars-v1.3.0.js"></script>
<script src="jquery.min.js"></script>
<script src="test.js"></script>
</head>
<body>
<script id="header" type="text/x-handlebars-template">
div {{ headerTitle }} div
Today is {{weekDay}}
</script>
</body>
</html>
And this is my Javascript
var theData = {headerTitle:"name", weekDay:"monday"}
var theTemplateScript = $("#header").html();
var theTemplate = Handlebars.compile(theTemplateScript);
$(document.body).append(theTemplate(theData));
I keep on getting the following error and i am unsure why
Uncaught Error: You must pass a string or Handlebars AST to Handlebars.compile.
You passed undefined
You are running Handlebars.compile() before theTemplateScript is loaded into the DOM. Move your test.js down below the template script and you should be good to go.
Moving the scripts to the bottom of the page also worked for me.
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<script id="header" type="text/x-handlebars-template">
div {{ headerTitle }} div
Today is {{weekDay}}
</script>
<script src="handlebars-v1.3.0.js"></script>
<script src="jquery.min.js"></script>
<script src="test.js"></script>
</body>
</html>
As others have said, the problem is that you are running Handlebars.compile() before the TemplateScript is loaded into the DOM.
Putting your javascript calls in $(document).ready() you make sure all the html is loaded first.
var theData = {headerTitle:"name", weekDay:"monday"}
$(document).ready(function(){
var theData = {headerTitle:"name", weekDay:"monday"}
var theTemplateScript = $("#header").html();
var theTemplate = Handlebars.compile(theTemplateScript);
$(document.body).append(theTemplate(theData));
});
in my case i was trying to assign some value to more deeper steps therefore, i faced the error.
Before my code was
app.use(function (req, res, next) {
res.locals.partials.weather = {}; = getWeatherData();
next();
});
and the problem was
res.locals.partials.weather
after removing the layer partial my problem was gone.
and the final code is
app.use(function (req, res, next) {
res.locals.weather = getWeatherData();
next();
});
In my case I got the same error but the issue was a typo in the template script in the html page. I had 'prouct-template' should have been 'product-template':
<script id="prouct-template" type="text/x-handlebars-template">
...
</script>
Once I fixed the typo the error went away and page loaded ok.
A bit of modification is needed in JavaScript file. I had the same issue. In my code, I called "handlebars" from Views (following explanation is with respect to views).
Include following in initialize function(init) of View :
theTemplate = Handlebars.compile(theTemplateScript);
In render write the remaining code :
var theTemplate = Handlebars.compile(theTemplateScript);
$(document.body).append(theTemplate(theData));
The correct way is to precompile the Handler, Store in file and then assign it to theTemplate.
You're using Handlebars.compile() before the template script loads. One simple trick would do the work for you. Use the defer tag in your script so that the entire body loads before the script runs in your <head> tag.
<head>
<script src="" defer> </script>
</head>
I'm following the video tutorials on egghead.io but while trying to follow his example when he created a factory (see video here) I keep getting "angular is not defined" Reference Error but I have included the angular script
This is my html page:
<!DOCTYPE html>
<html>
<head>
<title>Prototype</title>
<link rel="stylesheet" type="text/css" href="foundation.min.css">
<script type="text/javascript" src="main.js"></script>
</head>
<body>
<div data-ng-app="">
<div data-ng-controller="FirstController">
<input type="text" data-ng-model="data.message">
<h1>{{ data.message }}</h1>
</div>
<div data-ng-controller="SecondController">
<input type="text" data-ng-model="data.message">
<h1>{{ data.message }}</h1>
</div>
</div>
<script type="text/javascript" src="angular.min.js"></script>
</body>
</html>
and this is my javascript file "main.js":
//Services
// step 1 create an app
var myApp = angular.module('Data', []).
// tep 2 create factory
// Service name, function
myApp.factory('Data', function(){
return { message: "I'm Data from a Service" }
});
//Controllers
function FirstController($scope, Data){
$scope.data = Data;
}
function SecondController($scope){
}
I have read a few posts where similar happen (here) and please correct me if I'm wrong but I think it is to do with Boot strapping andI have tried manually bootstrapping using angular.bootstrap(document, ['Data']); but with no success, still get same error.
But What I want to know is, Why this works for so many examples online, like the egghead video series, but I have issues as I believe I have followed his video very closely. is it a change in angular in recent versions?
You have to put your script tag after the one that references Angular. Move it out of the head:
<script type="text/javascript" src="angular.min.js"></script>
<script type="text/javascript" src="main.js"></script>
The way you've set it up now, your script runs before Angular is loaded on the page.
You have not placed the script tags for angular js
you can do so by using cdn or downloading the angularjs for your project and then referencing it
after this you have to add your own java script in your case main.js
that should do
I had the same problem as deke. I forgot to include the most important script: angular.js :)
<script type="text/javascript" src="bower_components/angular/angular.min.js"></script>
