如何将 jquery 和其他.js库与 Angular2 一起使用

How to use jquery and other .js libraries with Angular2

本文关键字：Angular2 库与 一起 js 其他 jquery      更新时间：2023-09-26

我不知道这个问题是否属于Angular2。但是我正在使用Angular2，并希望使用HTML，CSS和JS集成此处显示的演示 - （请检查其工作演示和动画内容）。此演示显示了引导程序的轮播，其中包含动画内部内容。

这是我在 Plunker 中使用 Angular2 的演示。我尝试集成它，一切正常，除了我看不到旋转木马内部内容的动画，如文章所示。

另外请指导如何将jQuery和其他JS库与Angular2一起使用？

演示.js

*/
(function( $ ) {
    //Function to animate slider captions 
    function doAnimations( elems ) {
        //Cache the animationend event in a variable
        var animEndEv = 'webkitAnimationEnd animationend';
        elems.each(function () {
            var $this = $(this),
                $animationType = $this.data('animation');
            $this.addClass($animationType).one(animEndEv, function () {
                $this.removeClass($animationType);
            });
        });
    }
    //Variables on page load 
    var $myCarousel = $('#carousel-example-generic'),
        $firstAnimatingElems = $myCarousel.find('.item:first').find("[data-animation ^= 'animated']");
    //Initialize carousel 
    $myCarousel.carousel();
    //Animate captions in first slide on page load 
    doAnimations($firstAnimatingElems);
    //Pause carousel  
    $myCarousel.carousel('pause');

    //Other slides to be animated on carousel slide event 
    $myCarousel.on('slide.bs.carousel', function (e) {
        var $animatingElems = $(e.relatedTarget).find("[data-animation ^= 'animated']");
        doAnimations($animatingElems);
    });  
})(jQuery);

如何使用这个演示.js它包含 Angular2 应用程序中的 jQuery 代码？

你必须在 angular2 组件初始化后运行你的 jQuery 代码。我稍微改变了你的app.component.ts：

import {Component,OnInit} from 'angular2/core';
import {CORE_DIRECTIVES} from 'angular2/common';
declare var RunAnim;
declare var jQuery;
@Component({
    selector: 'my-app',
    templateUrl: 'mytemplate.html'
})
export class AppComponent implements OnInit { 
  constructor(){
  }
  ngOnInit(){
    RunAnim(jQuery);
  }
  ngAfterContentInit() {
  }
}

RunAnim和jQuery声明是为了在 TS 中可见，它们在全球范围内可用。

而你的jQuery代码我做了一个命名函数RunAnim：

/* Demo Scripts for Bootstrap Carousel and Animate.css article
* on SitePoint by Maria Antonietta Perna
*/
(window.RunAnim=function( $ ) {
    //Function to animate slider captions 
    function doAnimations( elems ) {
        //Cache the animationend event in a variable
        var animEndEv = 'webkitAnimationEnd animationend';
        elems.each(function () {
            var $this = $(this),
                $animationType = $this.data('animation');
            $this.addClass($animationType).one(animEndEv, function () {
                $this.removeClass($animationType);
            });
        });
    }
    //Variables on page load 
    var $myCarousel = $('#carousel-example-generic'),
        $firstAnimatingElems = $myCarousel.find('.item:first').find("[data-animation ^= 'animated']");
    //Initialize carousel 
    $myCarousel.carousel();
    //Animate captions in first slide on page load 
    doAnimations($firstAnimatingElems);
    //Pause carousel  
    $myCarousel.carousel('pause');

    //Other slides to be animated on carousel slide event 
    $myCarousel.on('slide.bs.carousel', function (e) {
        var $animatingElems = $(e.relatedTarget).find("[data-animation ^= 'animated']");
        doAnimations($animatingElems);
    });  
});
