Implement the addition of a class upon hovering using AngularJS

My goal is to include a new class when hovering over the li element using Angular in the code snippet below.

<li ng-mouseenter="cola-selected=true" class="pull-left" ng-class="{'selected' : cola-selected}">
    <a href="interna.html">
        <img src="assets/images/cola.png">
    </a>
</li>

This page only requires this specific functionality, so I'm considering whether adding a new JavaScript file is necessary.

The desired behavior is for the li element to have the new class selected upon mouse hover. However, the provided code is not functioning correctly and I am unable to determine the reason why.

You can find an example of my code on this fiddle: https://jsfiddle.net/mjrmeffc/

Answer №1

Is there a need for an additional file when you can simply incorporate the logic into your angular application?

I am assuming that you are utilizing ng-app and have a JavaScript file where your logic resides, which needs to be included here.

Here is an illustration of the correct method for adding/removing a class.

<div ng-app>
  <div 
    class="italic" 
    ng-class="{red: hover}" 
    ng-mouseenter="hover = true"
    ng-mouseleave="hover = false">
      Testing 1 2 3.
  </div>
</div>

Please note that I came across this in another stackoverflow question, it would be beneficial to conduct a thorough Google search before asking questions. Unfortunately, my reputation does not allow me to flag your query or leave a comment.

* UPDATE *

It appears that you may not yet be familiar with AngularJS. Remember to include your 'app.js' or 'script.js', where you will define your application using 

var app = angular.module('yourappname', [/* add your dependencies here*/]);

//Other implementations like controllers or services

In addition, your HTML should look something like

<div ng-app="yourappname">
 <div ng-controller="yourController">

BEFORE YOU BEGIN ASKING QUESTIONS, PLEASE FAMILIARIZE YOURSELF WITH THE BASICS

Answer №2

Experience the power of ng-mouseover attribute

<li ng-mouseover="hoverIn()" class="pull-left" ng-class="{{applyClass}}">

Create a function called hoverIn() in your code and specify actions for when hovering over an element

$scope.hoverIn = function() {
    this.applyClass = "red";
}
