In-depth Angular Animate framework technical principles in the Java library (In-Depth Explration of the Technical Principles of Angular Animate Framework in Java Class Libraries)
In -depth discussion of the technical principles of the Angular Animate framework in the Java library
Overview
Angular Animate is a powerful animation library in the Angular framework that is used to create rich and smooth animation effects in Web applications.This article will explore the technical principles of the Angular Animate framework in the Java class library, as well as providing some Java code examples to help readers better understand the framework.
Angular Animate framework
Technical principle
The technical principle of the Angular Animate framework mainly involves the following aspects:
1. Status and conversion: Angular Animate uses the concept of status and conversion to define the animation effect.Status refers to the different states of the element in the animation process, and the conversion refers to the switch between these states.By binding different states and conversions on HTML elements, we can create a variety of animation effects.
<button ng-mouseenter="hovered = true" ng-mouseleave="hovered = false" ng-class="{ 'hover': hovered, 'click': clicked }">按钮</button>
<button ng-click="clicked = true" ng-class="{ 'active': clicked }">按钮</button>
3. Transition and time control: The Angular Animate framework provides a mechanism for transition and time control to make smooth transitions between elements.Developers can specify the transition time, delay and slowing function, and the conditions for triggering transition.This can control the display and behavior of the animation more accurately.
The following example will show the transition effect between a element between displaying and hiding. The transition time is 500 milliseconds:
<div ng-show="visible" ng-an phrase="'FAde'" Class="Fate-Animation">元素</div>
css
.fade-animation {
transition: all 500ms linear;
}
.fade-animation.ng-hide {
opacity: 0;
}
Java code example
Below is a Java code example using the Angular Animate framework to create an animation effect:
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
@Controller
public class MyController {
@GetMapping("/")
public String index() {
return "index";
}
}
html
<!DOCTYPE html>
<html ng-app="myApp" ng-controller="myController">
<head>
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/animate.css/4.1.1/animate.min.css" />
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.8.2/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.8.2/angular-animate.js"></script>
<script>
angular.module('myApp', ['ngAnimate'])
.controller('myController', function ($scope) {
$scope.clicked = false;
$scope.toggleAnimation = function () {
$scope.clicked = !$scope.clicked;
};
});
</script>
</head>
<body>
<div class = "box" ng-class = "{'Animated': click, 'Shake': Clicked}"> Animation Effect </DIV>
</body>
</html>
This example shows a button. When you click the button, you will switch a box with a jitter effect.The animation effect of the box uses the Animate.css library, while the Angular Animate framework is used to handle status and conversion.
in conclusion
The Angular Animate framework is a powerful animation library in the Angular framework, which can help developers easily create interactive and rich and diverse animation effects.This article explores the technical principles of the Angular Animate framework and provides the corresponding Java code examples, hoping to help readers better understand and apply the framework.With the in -depth understanding of the Angular Animate framework, developers can add impressive animation effects to their applications.
