Ng Repeat Html AngularJs Example and Guide

The ng-repeat directive in AngularJS is a powerful tool for rendering dynamic HTML content. It's a shorthand for "repeat" and is used to iterate over a collection of items.

In AngularJS, ng-repeat is typically used within an HTML template to display a list of items. For example, if you have an array of objects in your controller, you can use ng-repeat to display each object as a separate HTML element.

To use ng-repeat, you'll need to specify the collection of items you want to render, as well as a template for each item. This template can include any HTML elements you like, and can even include other AngularJS directives.

The ng-repeat directive can be used with any type of collection, including arrays and objects. It's a versatile and powerful tool that can help you create dynamic and interactive web applications.

To display the list of items, you can use the HTML tags of and and then use the ngRepeat directive to go through each and every item in the array. The word "tpname" can be used to point to each item in the array, and the value of each array item can be displayed.

You can also use a more complex example, like the one shown in the Angular documentation, where a module and a controller are created to store functionality and keep the code modular and clean.

To create a list using ngRepeat, you need to add the array to the scope of the controller. A scope will be injected to the controller through the controller definition, and once the data is attached as an object property of the scope, it will be accessible to the view.

The ngRepeat expression "veg in veggies" is used to loop through the array automatically, and the moniker "veg" becomes the variable for a single value in the array as Angular loops through it. The "li" tag can then display the value of each array item by using {{veg.name}}.
