问题描述
我是Angular2的新手，并试图将Angularjs中的owl-carousel转换为Angular2.
I am new to Angular2 and was trying to convert owl-carousel in Angularjs to Angular2.
以下是猫头鹰轮播实现的index.html文件:
Below is the index.html file for the owl-carousel implementation:
<!DOCTYPE html>
<html ng-app="plunker">
<head>
<meta charset="utf-8" />
<title>AngularJS Plunker</title>
<script>document.write('<base href="' + document.location + '" />');</script>
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/owl-carousel/1.3.3/owl.carousel.min.css" />
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/owl-carousel/1.3.3/owl.theme.min.css" />
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/owl-carousel/1.3.3/owl.transitions.min.css" />
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/owl-carousel/1.3.3/owl.carousel.min.js" />
<script data-require="angular.js@1.3.x" src="https://code.angularjs.org/1.3.15/angular.js" data-semver="1.3.15"></script>
<script data-require="jquery@2.1.3" data-semver="2.1.3" src="http://code.jquery.com/jquery-2.1.3.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/owl-carousel/1.3.3/owl.carousel.min.js"></script>
<script src="app.js"></script>
</head>
<body ng-controller="MainCtrl">
<data-owl-carousel class="owl-carousel" data-options="{navigation: true, pagination: false, rewindNav : false}">
<div owl-carousel-item="" ng-repeat="item in ::items1" class="item">
<p>{{::item}}</p>
</div>
</data-owl-carousel>
<data-owl-carousel class="owl-carousel" data-options="{navigation: false, pagination: true, rewindNav : false}">
<div owl-carousel-item="" ng-repeat="item in ::items2" class="item">
<p>{{::item}}</p>
</div>
</data-owl-carousel>
</body>
</html>
这是app.js文件:
Here is the app.js file:
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.items1 = [1,2,3,4,5];
$scope.items2 = [1,2,3,4,5,6,7,8,9,10];
}).directive("owlCarousel", function() {
return {
restrict: 'E',
transclude: false,
link: function (scope) {
scope.initCarousel = function(element) {
// provide any default options you want
var defaultOptions = {
};
var customOptions = scope.$eval($(element).attr('data-options'));
// combine the two options objects
for(var key in customOptions) {
defaultOptions[key] = customOptions[key];
}
// init carousel
$(element).owlCarousel(defaultOptions);
};
}
};
}).directive('owlCarouselItem', [function() {
return {
restrict: 'A',
transclude: false,
link: function(scope, element) {
// wait for the last item in the ng-repeat then call init
if(scope.$last) {
scope.initCarousel(element.parent());
}
}
};
}]);
这是Angular1的实现方式，如何将其用于Angular2?
This is the Angular1 implementation how to implement it for Angular2?
推荐答案
更新
OwlCarousel2 + Angular2.3.0
ngOnDestroy() {
this.$owlElement.owlCarousel('destroy');
this.$owlElement = null;
}
旧版本
以下是angular2猫头鹰轮播实现的app.ts文件:
Below is the app.ts file for the angular2 owl-carousel implementation:
import {Component} from 'angular2/core';
import { OwlCarousel } from './owl-carousel.component';
@Component({
selector: 'app',
directives: [OwlCarousel],
template: `
<h2>Sample 1</h2>
<owl-carousel [options]="{navigation: true, pagination: false, rewindNav : false}">
<div *ngFor="#item of items1">
<p>{{ item }}</p>
</div>
</owl-carousel>
<h2>Sample 2</h2>
<owl-carousel [options]="{navigation: false, pagination: true, rewindNav : false}">
<div *ngFor="#item of items2">
<p>{{ item }}</p>
</div>
</owl-carousel>
<h2>Sample 3</h2>
<owl-carousel [options]="{navigation: false, pagination: true, rewindNav : false}">
<div *ngFor="#img of images">
<img src="http://lorempixel.com/400/200/{{img}}"/>
</div>
</owl-carousel>`
})
export class App {
items1: array = [1, 2, 3, 4, 5];
items2: array = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
images: array = ['sports', 'abstract', 'people', 'transport', 'city', 'technics', 'nightlife', 'animals'];
}
owl-carousel.component.ts
owl-carousel.component.ts
import { Component, Input, ElementRef } from 'angular2/core';
import $ from 'jquery';
import 'owl-carousel';
@Component({
selector: 'owl-carousel',
template: `<ng-content></ng-content>`
})
export class OwlCarousel {
@Input() options: object;
$owlElement: any;
defaultOptions: object = {};
constructor(private el: ElementRef) {}
ngAfterViewInit() {
for (var key in this.options) {
this.defaultOptions[key] = this.options[key];
}
this.$owlElement = $(this.el.nativeElement).owlCarousel(this.defaultOptions);
}
ngOnDestroy() {
this.$owlElement.data('owlCarousel').destroy();
this.$owlElement = null;
}
}
