For this tutorial, we\u2019ll have the hover functionality attached to a button.<\/p>\n<h2>1. Introduction<\/h2>\n<p><em>Angular<\/em> is a JavaScript MVC or Model-View-Controller framework developed by Google that lets developers build well structured, easily testable, and maintainable front-end applications. But before we start creating a real application using the angular library, let us see what the important parts of an angular application are.<br \/>\n[ulp id=&#8217;LXJcMJZXSsqGXYW8&#8242;]<\/p>\n<h4>1.1.1 Templates<\/h4>\n<p>In Angular, a <span style=\"text-decoration: underline;\">template<\/span> is an <code>HTML<\/code> with added markups. The angular library compiles the templates and renders the resultant <code>HTML<\/code> page.<\/p>\n<h4>1.1.2 Directives<\/h4>\n<p><span style=\"text-decoration: underline;\">Directives<\/span> are the markers (i.e. attributes) on a DOM element that tell angular to attach a specific behavior to that DOM element or even transform the DOM element and its children. Most of the directives in the angular library start with the <code>ng<\/code>. The directives consist of the following parts:<\/p>\n<ul>\n<li><code>ng-app<\/code>: The <code>ng-app<\/code> directive is a <em>starting point<\/em>. If the angular framework finds the <code>ng-app<\/code> directive anywhere in the <code>HTML<\/code> document, it bootstraps (i.e. initializes) itself and compiles the <code>HTML<\/code> template<\/li>\n<li><code>ng-model<\/code>: The <code>ng-model<\/code> directive binds an <code>HTML<\/code> element to a property on the <code>$scope<\/code> object. It also binds the values of angular application data to the <code>HTML<\/code> input controls<\/li>\n<li><code>ng-bind<\/code>: The <code>ng-bind<\/code> directive binds the angular application data to the <code>HTML<\/code> tags<\/li>\n<li><code>ng-controller<\/code>: The <code>ng-controller<\/code> directive specifies a controller in the HTML element. This controller will add behavior or support the data in that HTML element and its child elements<\/li>\n<li><code>ng-mouseover<\/code>: The <code>ng-mouseover<\/code> directive attaches a functionality to the <code>HTML<\/code> element on the mouse over event (i.e. whenever the mouse hover\u2019s on the <code>HTML<\/code> element, an event is triggered). This directive has the following prototype form:\n<pre class=\"brush:html; wrap-lines:false;\">&lt;html_element ng-mouseover=\"expression\" \/&gt;\r\n<\/pre>\n<p>Do <em>remember<\/em>, this angular directive does <strong>not<\/strong> interfere with the <code>onmouseover<\/code> event of the <code>HTML<\/code> element.<\/li>\n<\/ul>\n<h4>1.1.3 Expressions<\/h4>\n<p>An <span style=\"text-decoration: underline;\">expression<\/span> is like a JavaScript code usually wrapped inside the double curly braces such as <code>{{ expression }}<\/code>. Angular library evaluates the expression and produces a result.<\/p>\n<p>These new APIs make developer&#8217;s life easier, really! But it would be difficult for a beginner to understand this without an example. Therefore, let us create a simple application using the <code>ng-mouseover<\/code> directive to display a tooltip on hover.<\/p>\n<h2>2. AngularJS Hover Example<\/h2>\n<p>Here is a step-by-step guide for implementing the <code>ng-mouseover<\/code> directive in the angular web applications.<\/p>\n<h3>2.1 Tools Used<\/h3>\n<p>We are using Eclipse Kepler SR2, JDK 8 and Maven.
