I am having a problem which should have a simple solution. For some reason my action helper is not connecting to its method.
Here is my JSBin http://jsbin.com/UMaJaM/5/edit
Code is copied below for reference.
HTML:
<!DOCTYPE html>

JavaScript:
var TemplatedViewController = Ember.Object.extend({
templateFunction: null,
context: null,
viewBaseClass: Ember.View,
view: function () {
var controller = this;
var context = this.get('context') || {};
var args = {
template: controller.get('templateFunction'),
controller: controller
};
args = $.extend(context, args);
return this.get('viewBaseClass').extend(args);
}.property('templateFunction'),
appendView: function (selector) {
this.get('view').create().appendTo(selector);
},
appendViewToBody: function (property) {
this.get(property).create().append();
}
});
var template_source = '<button type="button" class="btn" {{action "button"}}>Click</button>';
var MyController = TemplatedViewController.extend({
templateFunction: Ember.Handlebars.compile(template_source),
button: function() {
console.log('hello world');
}
});
var controller = MyController.create();
$(function () {
controller.appendView('#main');
});
You need to create an Ember application. Add this to the beginning of your script:
App = Ember.Application.create();

Hello I have a simple HTML page like this:
<html>
<head>
</head>
<body>
<h1>Test page</h1>
<script type="text/javascript" src="script.js"></script>
<script type="text/javascript">
app.init([
"param", "123456789"
]);
app.execute();
app.edit();
</script>
</body>
</html>
The content of script.js is the following:
// Zepto include
...
// My code
var app = app || (function(){
var _args = {};
return {
init : function(Args) {
_args = Args;
},
execute : function() {
...
},
edit: function() {
$('body').on('click', function(e){
alert('aa');
});
},
};
}());
My problem is with this instruction $('body').on('click', function(e){.
I do not understand why.
It do not work.
Anyone to help me ?
I am trying to execute this code:
var addButton = document.querySelector("#add");
var searchButton = document.querySelector("#search");
var titleInput = document.querySelector("#title");
function Book(title) {
this.title = title;
}
function Library() {
this.books = [];
}
Library.prototype.add = function() {
this.add = function(book) {
this.books.push(book);
};
}
var library = new Library();
//Library UI
var libraryUI = {
//Add a new book
addBook: function() {
var listItem = libraryUI.createNewBook(titleInput.value);
Library.add(listItem);
console.log(Library.books);
},
//Create a new book
createNewBook: function(title) {
var book = new Book(title);
return book;
}
};
addButton.addEventListener("click", libraryUI.addBook);
The HTML is here:
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
<title>Library App</title>
<link rel="stylesheet" type="text/css" href="css/style.css">
</head>
<body>
<h1>Personal Library</h1>
<label for="title">Title: </label>
<input type="text" id="title">
<button id="add">Add</button>
<button id="search">Search</button>
<p id="display"></p>
<script src="js/app.js"></script>
</body>
</html>
What I'm trying to do is press the addButton and the onclick will run the addBook function under the libraryUI object. The title of the book, in an input field, will then be used to create an object with the title of the book in it. I want to add that book to a list of books (an array) in an instance of Library. When I try to do so with the following code, I get the error "Uncaught TypeError: Library.add is not a function". I thought that Library.add is a function.
I added:
var library = new Library();
because I thought I had forgotten to create an iteration of Library, but I still came up with the exact same error. Please help. :)
var addButton = document.querySelector("#add");
var searchButton = document.querySelector("#search");
var titleInput = document.querySelector("#title");
function Book(title) {
this.title = title;
}
function Library() {
this.books = [];
}
Library.prototype.add = function(book) {
this.books.push(book);
}
var library = new Library();
//Library UI
var libraryUI = {
//Add a new book
addBook: function() {
var listItem = libraryUI.createNewBook(titleInput.value);
library.add(listItem);
console.log(library.books);
},
//Create a new book
createNewBook: function(title) {
var book = new Book(title);
return book;
}
};
addButton.addEventListener("click", libraryUI.addBook);

Shouldn't it be library.add instead of Library.add?
Also: why:
Library.prototype.add = function() {
this.add = function(book) {
this.books.push(book);
};
}
instead of:
Library.prototype.add = function(book) {
this.books.push(book);
}
?
If I change Library.add to library.add and console.log(library.books) I think this does what you want.

Unknown provider: I18nServiceProvider <- I18nService
I want to use secure binding with knockout. to do so I use knockout-secure-binding.js.
Who could explain why the following code does not work?
it throws an error `
Uncaught #< Object > knockout-secure-binding.js:74`
after the line ko.applyBindings(new viewModel());
<html>
<head>
<title></title>
<script src="scripts/knockout-3.0.0-min.js"></script>
<script src="knockout-secure-binding-master/dist/knockout-secure-binding.js"></script>
</head>
<body>
<button type="button" data-sbind="sbtnClick">button</button>
<script>
var bindings = {
sbtnClick: function () {
return {click: this.btnClick};
}
};
var viewModel = function () {
this.btnClick = function () {
alert('clicked');
};
};
ko.bindingProvider.instance = new ko.secureBindingsProvider(bindings);
ko.applyBindings(new viewModel());
</script>
</body>
</html>
You still need to write out the name of the binding handler click:
<button type="button" data-sbind="click: btnClick">button</button>
And you don't need this whole bindings object with the sbtnClick, just write:
var viewModel = function () {
this.btnClick = function () {
alert('clicked');
};
};
ko.bindingProvider.instance = new ko.secureBindingsProvider();
ko.applyBindings(new viewModel());

I'm getting an error of "buildXML is not defined" when I run this code:
var c = {
updateConsumer:function (cid,aid,sid,survey){
var surveyXML = buildSurveyXML(survey);
},
buildSurveyXML: function(survey) {
var surveyResults = survey.split("|");
var surveyXML = '';
for (var i=0;i<surveyResults.length;i++){
...
}
return surveyXML;
}
}
And the html that includes this JS and calls the updateConsumer function:
<!DOCTYPE HTML>
<html lang="en">
<head>
<title>Web Service Test</title>
<meta charset="utf-8">
<script type="text/javascript" src="http://code.jquery.com/jquery-1.6.2.min.js"></script>
<script type="text/javascript" src="../../shared/js/consumerSoap.js"></script>
</head>
<body>
<script type="text/javascript">
$(document).ready(function() {
c.insertConsumer("First","Last","55555","name#url.com","76:1139");
});
</script>
</body>
</html>
The problem is that updateConsumer doesn't know anything about buildSurveyXML; that function isn't in the global scope. However, since your function is part of the same object, you can call it using the this keyword.
updateConsumer:function (cid,aid,sid,survey){
var surveyXML = this.buildSurveyXML(survey);
}
Use
var surveyXML = c.buildSurveyXML(survey);
