ng-repeat not working with table,in the output only header part displayed?
As i think the binding i did is perfectly fine, but something is there which i am missing?
Can anyone help me out where i am doing wrong?
JAVA SCRIPT:
var myapp=angular.module("MyApp",[]);
var controller=function($scope)
{
var technology1=[
{Name: "C#",Likes: 0,Dislikes: 0},
{Name: "JAVA",Likes:0,Dislikes:0},
{Name: "Python",Likes:0,Dislikes:0}
];
$scope.technology=technology1;
$scope.incrementLikes=finction(technology)
{
technology.Likes++;
}
$scope.discrementLikes=function(technology)
{
technology.Dislikes++;
}
}
myapp.controller('MyController',controller);
<html ng-app="MyApp">
<head>
<title></title>
<script src="angular.js"></script>
<script src="Day2.js"></script>
</head>
<Body ng-controller="MyController">
<div >
<table border='2'>
<thead>
<tr>
<th>Name Of Technology</th>
<th>Likes</th>
<th>Dislikes</th>
<th>Likes/Dislikes</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="tech in technology">
<td>{{tech.Name}}</td>
<td>{{tech.Likes}}</td>
<td>{{tech.Dislikes}}</td>
<td>
<input type="button" value="Like" ng-click="incrementLikes(tech)">
<input type="button" value="Dislikes" ng-click="decrementLikes(tech)">
</td>
</tr>
</tbody>
</table>
</div>
</Body>
</html>
Replace this line
$scope.incrementLikes=finction(technology)
by
$scope.incrementLikes=function(technology)
Your code has a typo in your myController controller. Change finction to function.
As Pankaj Parkar pointed out you need to correct the "finction" typo as well as to reference the $scope.technology.Likes and $scope.technology.dislikes when you are incrementing their values.
So update these lines:
$scope.incrementLikes=finction(technology)
{
technology.Likes++;
}
$scope.discrementLikes=function(technology)
{
technology.Dislikes++;
}
To this
$scope.incrementLikes=function(technology)
{
$scope.technology.Likes++;
}
$scope.discrementLikes=function(technology)
{
$scope.technology.Dislikes++;
}
Here's the fully corrected code. I can't comment on the answer from #pzelenovic but do NOT add "$scope.technology.Likes++;" or "$scope.technology.Likes++;" to your increment/decrement functions. Those are fine the way they are because you're updating the likes/dislikes property on the "tech" object you passed in from the click function.
var myapp=angular.module("MyApp",[]);
var controller=function($scope)
{
var technology1=[
{Name: "C#",Likes: 0,Dislikes: 0},
{Name: "JAVA",Likes:0,Dislikes:0},
{Name: "Python",Likes:0,Dislikes:0}
];
$scope.technology=technology1;
$scope.incrementLikes=function(technology)
{
technology.Likes++;
}
$scope.decrementLikes=function(technology)
{
technology.Dislikes++;
}
}
myapp.controller('MyController',controller);

I am using a asp.net mvc web app. I have created a table and now I am wanting to use the plugin in datatables. I saw you only needed 3 lines of code to make this work. I attempted to do exactly what it required in order for it to work and give me the desired datatable, but it does not give me the table I am expecting. I even went to examples -> HTML (DOM) source data -> and under Javascript tab I entered the lines required.
Is there something I am doing incorrect here with the script tags or is the plug in just not working? I do not have the files downloaded and imported to my project.
Expecting a standard look like this
But am getting this... so I am missing the look of the datatable plugin and the following Error.
Cannot set properties of undefined (setting '_DT_CellIndex')
my view:
#model List<Fright>
#{
ViewData["Title"] = "Home Page";
var result = Model.GroupBy(gb => gb.Value);
}
<!DOCTYPE html>

<script type="text/javascript" charset="utf8" src="//cdn.datatables.net/1.11.2/js/jquery.dataTables.min.js" defer></script>
<script>
$(document).ready(function () {
$('#homeTable').DataTable();
});
</script>
</head>
<body>
<div>
<table id="homeTable" class="display" style="width:100%">

<tbody>
#foreach (var item in result)
{
var url = "/frightSummary/SummaryIndex?id=" + item.Key;
<tr>
<td>
<a href=#url>#item.Key</a>
</td>
</tr>
}
</tbody>
</table>

Your problem is a mismatch in the number of <td> </td>. You are just rendering 1 <td> in foreach loop but you have two <th></th> in the table header
#model List<Fright>
#{
ViewData["Title"] = "Home Page";
var result = Model.GroupBy(gb => gb.Value);
}
<!DOCTYPE html>
<html>

<script src="https://code.jquery.com/jquery-3.5.1.js"></script>

#foreach (var item in result)
{
var url = "/frightSummary/SummaryIndex?id=" + item.Key;
<tr>
<td>
<a href=#url>#item.Key</a>

is there something wrong with the code below
Just trying to fix decimal paces for a specific class of td.
need to use only jquery
<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
<script src= "https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
</head>
<body>
<td class="go"> 25.252525
</td>
<script type="text/javascript">
$('.go').each(function() {
return parseFloat($(this).toFixed(2));
}
</script>
</body>
</html>
You need to use .text() to get text from td then use .toFixed() and finally change updated value inside your td i.e : $(this).text(parseFloat($(this).text()).toFixed(2));
Demo Code :
$('.go').each(function() {
$(this).text(parseFloat($(this).text()).toFixed(2)); //change text..
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
<table>
<tr>
<td class="go"> 25.252525
</td>
</tr>
<tr>
<td class="go"> 25.2223525
</td>
</tr>
</table>
My JS code looks like this. But when I open the page it says "Uncaught TypeError: Cannot set property 'innerHTML' of null"
I tried to change the NewItem constructor to a function. But VSC keeps saying I should declare it as a class instead. I converted it in the first place because the constructor wasn't working as a function either.
class NewItem {
constructor(name, date, price) {
this.itemName = name;
this.itemDate = date;
this.itemPrice = price;
}
}
const onListItem = new NewItem("John", "Date", "Price");
document.getElementById("demo").innerHTML = onListItem.itemDate;
HTML looks like this
<!DOCTYPE html>
<html lang= "en">
<head>
<link rel="stylesheet" href="ShopListStyle.css">
<meta name="viewport" content="width=device-width" initial-scale=1.0>

Your JavaScript code is trying to access this element with id demo (<p id="demo"></p>):
document.getElementById("demo").innerHTML = onListItem.itemDate;
Your script is added at the opening body tag...
<body>
<script src="ShopListScript.js"></script>
...
...which means the demo element does not exist yet.
Solution: Put your script before the closing body tag:
...
<script src="ShopListScript.js"></script>
</body>
</html>
You can also try to set
<script src="ShopListScript.js" defer="defer"></script>
Because javascript will block the DOM rendering, so we should put in the end of
like Peter Krebs's answer:
...
<script src="ShopListScript.js"></script>
</body>
I just got a book called "Pro Angular" from Apress by Adam Freeman. I have never used Angular JS before and I am not really sure why this isn't working but I'll explain where I am currently. Ok, so the first project I am currently doing is a basic to do list using Angular to bind certain data to html tags using data-binding and I've just added a line defining a module. Problem is my environment is claiming that the module is not being defined. I'm not sure what it is talking about. Here is my source so far.
<!DOCTYPE html>
<html ng-app="todoApp">
<head>
<title>TO DO List</title>
<link href="bootstrap.css" rel="stylesheet" />
<link href="bootstrap-theme.css" rel="stylesheet" />
<script src="angular.js"></script>
<script>
var model = {
user: "Adam",
items: [{ action: "Buy Flowers", done: false },
{ action: "Get Shoes", done: false },
{ action: "Collect Tickets", done: true },
{ action: "Call Joe", done: false }]
};
var todoApp = angular.module("todoApp", []);
todoApp.controller("ToDoCtrl", function ($scope) {
$scope.todo = model;
});
</script>
</head>
<body ng-controller="ToDoCtrl">
<div class="page-header">
<h1>
{{todo.user}}'s To Do List
<span class="label label-default">{{todo.items.length}}</span>
</h1>
</div>
<div class="panel">
<div class="input-group">
<input class="form-control" />
<span class="input-group-btn">
<button class="btn btn-default">Add</button>
</span>
</div>
<table class="table table-striped">
<thead>
<tr>
<th>Description</th>
<th>Done</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="item in todo.items">
<td>{{item.action}}</td>
<td><input type="checkbox" ng-model="item.done" /></td>
<td>{{item.done}}</td>
</tr>
</tbody>
</table>
</div>
</body>
</html>
The line it is talking about is Ln-18. Any help with an explanation would be greatly appreciated.
The header 'Speedruns' keeps getting repeated. How can I fix this?
Also, if there is a better way to do this please let me know.

var app = angular.module('player2', []);
app.controller('MainController', function($scope, $http) {
$scope.data0 = null;
$scope.urls = [ // List of REST api calls with with all the streams we want.

$http.get($scope.urls[0]).success(function(data) {
$scope.data0 = angular.fromJson(data);
console.log(angular.fromJson(data))

Attached a plunker with the code in it.
Plunker
The thing you want to repeat is the tr, so put your repeat on there. At the moment you are repeating whole the table. The following should work:
<table class="table-size" >
<tr>
<th class="text-center" colspan="2">Speedruns</th>
</tr>
<tr ng-repeat="chan in data0.channels">
<td class="text-left">{{chan.channel.display_name}}</td>
<td class="text-left">{{chan.channel.current_viewers}}</td>
</tr>
</table>
