My custom directive is not working:
html:
<body ng-controller="StoreController as store">
<ul class="list-group">
<li class="list-group-item" ng-repeat="product in store.products">
<div>
<h3>
<product-title></product-title>
</h3>
...
javascript.app:
...
app.directive('productTitle', function(){
return {
restrice: 'E',
templateUrl: 'product-title.html'
};
});
...
and my product-title.html:
{{product.name}}
<em class="pull-right"> {{product.price | currency}}</em>
in my html page i cant see the product name and product price.
I am new in this subject :)
what should i do to make it work?
please help me.
++thanks everyone for yours answers, it is works! i tried for 3 days to find an answer.. and you did it in 5 min.. thanks! :)++
Couple of issues:
restrict is spelled wrong
Templates for html should have one root, so you should do something like this
<div>
{{product.name}}
<em class="pull-right"> {{product.price | currency}}</em>
</div>
Here is the complete running code for your directive in this JSBin
JS
angular
.module('app', [])
.controller('AppController', function ($scope) {
$scope.store = {
products: [
{ id: 1, price: 132, name: 'abc' },
{ id: 2, price: 127, name: 'def' },
{ id: 3, price: 112, name: 'mno' },
{ id: 4, price: 145, name: 'xyz' }
]
};
})
.directive('productTitle', function(){
return {
restrict: 'E',
templateUrl: 'product-title.html'
};
});
HTML
<div ng-controller='AppController'>
<ul class="list-group">
<li class="list-group-item" ng-repeat="product in store.products">
<h3>
<product-title></product-title>
</h3>
</li>
</ul>
</div>
<script id="product-title.html" type="text/ng-template">
{{product.name}}
<em class="pull-right"> {{product.price | currency}}</em>
</script>

I trying to use directives to show controller data in the my view but nothing displays and there are no errors in the console. I am able to log the data but the data will not show in view. Am I using directives the correct way? How do I show the data in the view? Thank you.
index.html
<body ng-app="GameboardApp">
<div class="header">
<h1 class="logo">GameBoard</h1>
</div>
<div class="main" ng-controller="ScoreController">

<game ng-repeat="score in scores" info="score"></game>

In game.js file, where you have created the directive, you have misspelled the field name. It should be scope not score.
I've created a simple app that should iist each item from a model in a list, created using a javascrit template.
Fiddle
Html:
<div id="tagsList" class="box">
<div class="box-head">
<h2 class="left">Tags</h2>
</div>
<div class="box-content">
<input type="text" placeholder="Add New Tag" />
<button>+ Add</button>
<div data-bind="template: 'tagsTempl'"></div>
</div>
</div>
<script id="tagsTempl" type="text/html">
<ul>
{{each tags}}
<li class="tagItem">
<span>${Name}</span>
<div>
Edit
Delete
</div>
</li>
{{/each}}
</ul>
</script>
Javascript:
$(function () {
//$("#tagDialog").hide();
var data = [
{ Id: 1, Name: "Ball Handling" },
{ Id: 2, Name: "Passing" },
{ Id: 3, Name: "Shooting" },
{ Id: 4, Name: "Rebounding" },
{ Id: 5, Name: "Transition" },
{ Id: 6, Name: "Defense" },
{ Id: 7, Name: "Team Offense" },
{ Id: 8, Name: "Team Defense" }
];
var viewModel = {
tags: ko.observableArray(data),
tagToAdd: ko.observable(""),
addTag: function() {
this.tags.push({ Name: this.tagToAdd() });
}
}
ko.applyBindings(viewModel)
});
Output of list:
{{each tags}}
${Name}
Edit Delete
{{/each}}
The scripts file is accessible through viewing source. I'm not sure where my error is. Any help?
I updated your fiddle. Now it is working like you want it to: The list of tags is being rendered using the knockout standard method as described in the docs.
HTML
<ul data-bind="template: {name: 'tagsTempl', foreach: tags}"></ul>
Template
<script id="tagsTempl" type="text/html">
<li class="tagItem">
<span data-bind="text: Name"></span>
<div>
Edit
Delete
</div>
</li>
</script>
Also I connected the viewmodel to the view.
For example:
<button data-bind="click: addTag">+ Add</button>
You simply forgot most of it. I suggest you follow the interactive tutorials on how to do this.
I am new to AngularJS. I cannot get my controller to work. However, ng-init works perfectly. This is the code:
<div data-ng-controller="SimpleController">
<input type="text" data-ng-model="yourName" placeholder="Enter a name here">
<h3>
<ul>
<li data-ng-repeat="cust in customers | filter:yourName | orderBy : 'name'"> {{ cust.name | uppercase }} - {{ cust.city | uppercase }} </li>
</ul>
</h3>
</div>
<script src="js/angular.min.js"></script>
<script>
function SimpleController($scope) {
$scope.customers = [{
name: 'rutunj',
city: 'surat'
}, {
name: 'aushik',
city: 'Jugal'
}, {
name: 'kushik',
city: 'Lugal'
}];
}
</script>
In script you have done this
function SimpleController($scope) {
$scope.customers = [{
name: 'rutunj',
city: 'surat'
}, {
name: 'aushik',
city: 'Jugal'
}, {
name: 'kushik',
city: 'Lugal'
}];
}
But you haven't define angular module so change code as below inside script.
angular.module('myApp', []).controller('SimpleController', SimpleController);
function SimpleController($scope)
// Controller code
}
and add ng-app in div like
<div ng-app="myApp" data-ng-controller="SimpleController">
I'm trying to get to grips with AngularJS and had this working to echo individual things from a controller, but when I tried to incorporate a loop with ng-repeat all I get is {{tasks.title}} flashing onscreen for a second, then a blank empty div.
Any examples I've looked up seem a little different and I've tried a few ways, can anyone see where I'm going wrong?
Controller:
app.controller('MainController', ['$scope', function($scope) {
$scope.tasklist = {
tasks: [{
title: 'Wash Dog'
}, {
title: 'Email Joe'
}]};
}
]);
HTML:
<section class="panel">
<div ng-controller="MainController">
<div class="thumbnail" ng-repeat="tasks in tasklist">
<p>{{ tasks.title }}</p>
</div>
</div>
</section>
You are accessing the property tasklist not the actual tasks. It should be tasklist.tasks
<section class="panel">
<div ng-controller="MainController">
<div class="thumbnail" ng-repeat="tasks in tasklist.tasks">
<p>{{ tasks.title }}</p>
</div>
</div>
</section>
Another way would be to remove the tasks property:
app.controller('MainController', ['$scope', function($scope) {
$scope.tasklist = [
{
title: 'Wash Dog'
},
{
title: 'Email Joe'
}
];
}]);

Why isn't anything rendering?
templateUrl is an argument to your directive. You should not have it in your scope. Your directive doesn't know what to render!
scope = {...},
templateUrl = '...'
