It will be a very basic question about a problem I encountered. Nothing is specially hard in the work I intend to do, but I really don't see why it isn't working, as my code is almost the same as some examples in AngularJS documentation.
So here it is :
I'm trying to create a basic website to entertain myself on developping with Mean Stack).
I made a mere index.html page :
<!DOCTYPE hmtl>

<script type="text/javascript" src="./jquery.js"></script>

<script type="text/javascript" src="./bootstrap.min.js"></script>
And that's for the HTML page, the interesting part is notified. I use a serveur.js file which is following :
var app = angular.module('preBoot', []);
app.controller('mainController', function($scope){
$scope.posts = [];
$scope.newPost={created_by: '', text: '', created_at: ''};
$scope.post= function(){
$scope.newPost.created_at = Date.now();
$scope.posts.push($scope.newPost);
$scope.newPost = {created_by: '', text: '', created_at: ''};
};
});
Finally, I run everything using the serveur.js file I run with the node.js invite command.
var express = require('express');
var path = require('path');
var app = express();
app.use(express.static(__dirname));
app.get('/', function(req, res) {
res.sendFile('./index.html');
});
// Allow the error 404 selection
/* app.use(function(req, res, next){
res.setHeader('Content-Type', 'text/plain');
res.send(404, 'Page introuvable !');
}); */
app.listen(8081);
For simplicity purposes, I temporarly put every single file in the same folder, so everything (every ccs and js file is in the same folder of my html).
What I get when I run the program is :
My screenshoot
Which is pretty much what I want except when I type something, the text doesn't appear, which does not make any sense to me.
I correctly installed the npm express before in a node_module folder put in the same place than my index.html file.
Sorry to bother with that uninteresting problem, I spend hours trying to fix that problem and one more searching for any solution in the questions already asked, but everything I found didn't fix the issue.
NB : I work on Windows.
The main problem is you have defined
ng-app=""
and you have defined the controller on preBoot app
var app = angular.module('preBoot', []);
app.controller('mainController', function($scope){
Either define the controller like this
function mainController($scope){
OR define the ng-app="preBoot"
Others mistakes are
Your controller is bound to form only
<form ng-submit="post()" ng-controller="mainController">
<input required type="text" placeholder="Your name" ng-model="newPost.created_by"/>
<textarea required maxLength="200" rows="3" placeholder="Say something" ng-model="newPost.text"></textarea>
<input class="button" type="submit" value="Preboot that!"/>
</form>
This code is out of controller scope
<div class='post' ng-repeat="post in posts" ng-class-odd="'odd'" ng-class-even="'even'">
<p> {{post.text}} </p>
</div>
I did short your code and have made a jsfiddle. Working fine.
check it
https://jsfiddle.net/Lt7aP/2926/
In jsfiddle code update ng-app="preBoot" to ng-app="" you will get the error Argument 'mainController' is not a function, got undefined

I'm kinda new to all of this, but I have a JSF Web Application (which works) which also has a Google Authentication (google authentication works by itself);
I'm trying to pass the response from the google Auth to the JSF login (the email address & google Id) which will then authenticate via a JdbcRealm;
So just to clarify, the JSF authentication via a JdbcRealm works by itself, and the google login by itself works - i just want to pass the response from google (of the email address & google id) to be used as the JSF authentication, & automate the click action of the JSF auth form.
My issue is, that after i log into google, i get the error
TypeError: document.getElementById(...) is null
Here's my JSF login page with all the Javascript;

I found the answer to my own problem;
With my error message, the problem was obviously in the way i was trying to access the "j_username" & "j_password elements:
TypeError: document.getElementById(...) is null
Anyway, by changing the code i had:
document.getElementById("login.j_username").value = googleUser.getBasicProfile().getEmail();
To instead look like this:
document.getElementById("login").elements[1].value = googleUser.getBasicProfile().getEmail();
In short, the problem was the way i was trying to address the elements of the form, and by addressing the form itself, and then the elements of the form (being in a 0 based array), then it works
This is my first time asking or doing this type of question
So I created this page http://lamp.cse.fau.edu/~mcuervo5/p4/
and it does your basic to do app list thing for adding and deleting stuff.
Apparently the only thing missing is to save the data on the current page. I heard that there a code that can save the current page to a local storage that has everything already in it, so when I re-open the link, instead of having nothing in the "complete and incomplete" list, it should look like this
thanks, it the only part I have left to do & I dont know if it implemented in HTMl or Jquery. I do not know how to do it.
and if you want to see the code here instead of "inspect" from the page with the link above, here it is. for html and Jquery
$(document).ready(function() {
// $('#list').innerhtml = localStorage.getItem("List");
//$('#incomplete-tasks').html("<P>I just replaced your stuff.</P>");
$("#Sumbit_Button").click(function() {
var textbox_Value = $("#textbox").val();
$('#incomplete-tasks').append('<li><span class="text" contenteditable="false">' + textbox_Value + "</span>" +
'<input/ style="display: none" class="new-value">' +
"<button type='button' class='delete'>Delete</button>" +
"<button type='button' class='edit'>Edit</button></li>");
});
$('#incomplete-tasks').on('click', '.delete', function() {
console.log('i am clicked.delete');
$(this).parent().remove();
});
$('#incomplete-tasks').on('click', '.edit', function() {
console.log("complete task click.edit");
$(this).siblings('input').show();
$(this).siblings('.delete').hide();
$(this).hide();

Hello you can do something like this:
$("#Sumbit_Button").click(function() {
var textbox_Value = $("#textbox").val();
var list = [];
list.push(textbox_Value);
localStorage.setItem("listdata", list);
// do not manage using `append` whole html. Manage through list and display as you want
});
on page load call:
var stored = localStorage.getItem("listdata");
Now here you can manage array of items and iterate on complete & incomplete list.
So whenever any action of edit, delete, add occurs you have to just manage the localstorage instance on each call. and based on that just iterate list whereever you want.
So I've set up ui-router and I had it working a few minutes ago, sort of, it would display the template with content loaded from another html file, but none of the links would work. Now nothing is working: the template shows up but the content is not pulled in and none of the links work.
Ctrl.js
var site = angular.module('site', ['ui.router']);
site.config(function($stateProvider, $urlRouterProvider) {
$stateProvider
.state('page', {
url: '/page',
templateUrl: 'page.html',
})
.state('about', {
url: '/about',
templateUrl: 'about.html',
});
$urlRouterProvider.otherwise('/page');
})

Wow you all are fast! Thanks for the suggestions. So update: changing it to ahref="#/about" helped in that I can now go to the link but still no content displays. There is a console error:

Your state URL is /about, not /about.html.
In any case, use the ui-sref directive, that's what it's for
<a ui-sref="about">about</a>
You simply pass in the state name (and any params, see the documentation) and it will create the right URL for you taking into account any $locationProvider.html5mode configuration.
If you are loading the app via file:///some/path/to/index.html, the AJAX requests to your templates (ie about.html) might not work. You should be using an HTTP server for your local development.
Have a look at (or even just clone as a base) the angular-seed project. It provides an excellent starting point for first-time Angular development.
You are mistake the state URL
your code <li>about</li>
You can access the state by URL from browser, but referencing other section of the app is a bad practice though it still works
<li>about</li>
Do this
<li><a ui-sref="about">about</a></li>
your state URL is mistake, is /about not /about.html
Try this
<li><a ui-sref="about">about</a></li>
For link to work you need to use
about
instead of
about.
Also for content to pull in like data binding you need to use controller.
Try this, just make sure test.html be there.

after watching this presentation (https://www.youtube.com/watch?v=ImR0zo1tA_I) I wanted to try Angular JS. I copied the code, exactly what was on the screen, but i doesn't work. I tried it in my browser, in my page (http://thecodemaker.com.pl), I was doing research about AngularJS but it still doesn`t want to work.
Code :

<script src="js/bootstrap.min.js"></script>

<script>
angular.module("basicApp", [])
.controller("TodoController", ["$scope", function($scope) {
$scope.todos =['Buil an atomic bomb','Sell it on ebay']
}
</script>
</body>
</html>
Any ideas what is wrong ?
There seems to be a lot wrong with your snippet. For one, your submit/add button is not bound to an event listener or anything so it's not doing anything that you'd want (like adding an item to the property on your controller's $scope).
Check out the Todo example on Angular's official website, it's more up to date.
https://angularjs.org/ (scroll down).
Here's the video for it: https://www.youtube.com/watch?v=WuiHuZq_cg4
There is an error : Bootstrap's JavaScript requires jQuery, which means you need to add jQuery library to your project, required by bootstrap.js
Starting with Angular 1.3.x, you can no longer declare a controller as a generic global function on window. Controllers must now use the more current form of component declaration.
<script>
angular.module("basicApp", [])
.controller("TodoController", ["$scope", function($scope) {
$scope.todos =['Buil an atomic bomb','Sell it on ebay']
}
</script>
In the HTML, change ng-app="" to ng-app="basicApp.
I'm learning AJAX for the first time and I'm trying to create a simple application that calculates the grade a person needs to get on their final exam based on their previous assessment results.
The user inputs their grades into the form and then using ajax I calculate the response in response.php which should then be output in the callback function in the div with ajax as its id.
For some reason the xhr.readystate property is never reaching 4 so the response is never generated. Can anybody see what I'm doing wrong?
Please bear in mind I'm only learning...

Here is response.php
<?php
$currentGrade = $_GET['currentGrade'];
$targetGrade = $_GET['targetGrade'];
$finalWorth = $_GET['finalWorth'];
$neededMark = $currentGrade - $targetGrade;
$neededMark = $neededMark / $finalWorth;
$neededMark = $neededMark * 100;
$neededMark = round($neededMark);
if(isset($currentGrade, $targetGrade,$finalWorth)) {
echo $neededMark;
}
?>
The correct order of operations is:
construct
open
set handler
send
You are doing them in the order 1324, which is incorrect and therefore likely to not behave as expected.
Put things in the right order, see if that works :)
EDIT: Additionally, remove all document.write calls. They will not work with any asynchronous operation and will almost certainly break things.
EDIT EDIT: Also, <button type="submit" class="btn btn-default" onclick="sendAjax()"> - this should be type="button", otherwise your form will be submitted and it will look like it did nothing.
doesn't look like you are sending any parameters in your ajax request so response.php is not GETting any data...
if it were xhr.open("GET","response.php?param1=value1¶m2=value2"); etc you should get something
Only one small change is required
In form division make instead of submit. Because on submit the forms behaviour is different as compared to just a button click
