PhotoSwipeJs_ohos

本项目是基于开源项目photoSwipe进行鸿蒙JS API的功能化移植和开发的,在功能实现上属于功能重写。可以通过项目标签以及github地址(https://github.com/dimsemenov/PhotoSwipe/tree/master/dist)追踪到原JS项目版本。

项目介绍

  • 项目名称:PhotoSwipeJs_ohos(相册画廊组件)
  • 所属系列:鸿蒙的第三方组件适配移植
  • 功能:实现点击预览图片放大缩小特效、手指滑动,其他功能有标题栏等
  • 项目移植状态:100%,已完成核心功能移植
  • 调用差异:功能重构
  • 编程语言:Js
  • 外部库依赖:无
  • 开发版本:sdk7(版本向下兼容),DevEco Studio3.0 beta1
  • 项目发起作者:蔡志杰
  • 邮箱:isrc_hm@iscas.ac.cn
  • 原项目Doc地址:[https://github.com/dimsemenov/PhotoSwipe/tree/master/dist]

由于本项目基于JS版本移植开发,在开发中并未借鉴原开源项目photoSwipe的代码,只参照该功能,基于方舟开发框架ArkUI实现类似功能,需要注意的是,该版本为HarmonyOS适配版本。

使用教程

  1. 组件的实现位于 entry/src/main/js/default/common/components/ 中,将组件复制至自己的项目中即可调用这些组件。下面我们以 imagePreview为例演示组件的调用方法,其它组件同理。

  2. 在 hml 文件中添加 imagePreview并绑定组件所需参数。

    <element name="photoswiper" src="../../common/component/imagePreview/preview.hml"></element>
    <!--测试代码-->
    <photoswiper  @handle-result="onResReceived" image-list="{{imgList}}"></photoswiper>

    image-list 指定了图片的 url、图片详情信息,自定义事件 handle-result 将验证结果返回给父组件。

  3. 在 js 文件中定义组件参数和事件处理函数。主要涉及三个步骤:

  • 指定图片源

    对于画廊组件PhotoSwipeJs_ohos我们需要指定图片源数组。此处我们选择本地资源图片的 url,使用 url 字符串组成的数组初始化 imglist,另外选择添加标题txt、介绍text。

  • 指定组件参数

    对于画廊组件,参数对象具有如下属性:

    • PhotoSwipeJs_ohos
    参数名 解释
    txt 照片标题
    text 照片详情
    image 照片url地址
    • 指定事件处理函数

    在绑定事件处理函数后,在父组件中可以通过 e.detail.result 获取子组件的验证结果。

js 具体代码如下:

import prompt from '@system.prompt';

export default {
    data: {
        title: "",
        // 可以增加数据行,包括图片与图片介绍
        // txt--标题 text--介绍 image--图片地址
        imgList:[
            {
                txt: '元气森林',
                text: '川涘将钓玉,乡亭期散金。 素晖射流濑,翠色绵森林。',
                image: '/common/images/test1.jpg'
            },
            {
                txt: '小岛极光',
                text: '马沙少个天灯塔,暗雨乌风看作标。',
                image: '/common/images/test2.jpg'
            },
            {
                txt: '腊雪寒冬',
                text: '凌兢侵腊雪,散漫入春诗。赠我岁寒色,怜君冰玉姿。',
                image: '/common/images/test3.jpg'
            }
        ],
    },
    onInit() {
        this.title = this.$t('strings.world');
    },
    // 事件处理函数,在此处定义验证完成后的操作
    onResReceived(e) {
        prompt.showToast({
            message: "父组件得到结果:" + e.detail.result
        });
    }
}
