javascript - AngularJS- ionic : create a swipeable horizonatlview which will update vertical view

Question

我想使用 angularjs 和 ionic 创建适用于 Android 和 iOS 的 UI。 View 如下:

说明:在这个 View 中，我想要一个包含日期的水平条(当前显示 1 到 8 个日期，但它可以从每月的第 1 天到每月的最后一天滑动)。该条可左右滑动。每天都会有一些数据显示在垂直 ListView 中。当用户同时在水平条上向左或向右滑动时，垂直数据将更新。垂直 ListView 将仅显示水平条中显示的日期的数据。

我不确定我该怎么做。任何指针，例如库/示例代码等将不胜感激。

谢谢

Answer 1

我会推荐 swiper ，我以前用过它，我发现它简单易用:http://idangero.us/swiper/ , http://idangero.us/swiper/get-started/

文档:http://idangero.us/swiper/api/

Swiper is also a default slider component in Ionic Framework

快速概览:

你可以配置它显示x一次滑动，中间的总是有 swiper-slide-active类(class)，你有事件slideChange当 swiper-slide-active 时被触发被改变了，你可以输入你想要的任何函数(也许是一个 ajax 函数来获取当天的数据)它只是被解雇了一点，所以你需要把它包装在 setTimeout 中。的 1ms

我根据你的布局做了一个基本的例子，这里有一个你可以玩的 fiddle ，并根据你的需要改变它:

编辑

显示7天范围内的数据，centeredSlides: true被删除所以swiper-slide-active成为左边的第一张幻灯片，所以这是你的 startDate , 加 6 得到 endDate

编辑2

要实时跟踪天数，您可以使用事件 sliderMove检测 slider 是否在移动并在它移动时做一些事情，你可以存储 offsetLeft Array 中的每张幻灯片并在用户滑动并将值与当前 offset 进行比较时循环遍历它刷卡器，然后 break当比赛不继续通过 loop

编辑片段:

var content = document.getElementById('content');
	
var currenOffset; // swiper's offset
var childOffset; // slide's offset
	
var startIndex; 
var endIndex;
	
var slides = document.getElementsByClassName('swiper-slide');
var slidesOffsets = [];
  
var swiper = new Swiper('.swiper-container', {
  slidesPerView: 7,
  spaceBetween: 10,      
  on: {
    init: function () {
      setTimeout(function(){
        var startDay = document.getElementsByClassName('swiper-slide-active')[0].innerHTML;
        var endDay = parseInt(startDay) + 6 ;            
        content.innerHTML = '<div> Showing data for days ' + startDay + ' to ' + endDay + '</div>';
      }, 1);
    }
  }
});
	
swiper.on('slideChange', function () {
  setTimeout(function(){
    var startDay = document.getElementsByClassName('swiper-slide-active')[0].innerHTML;
    var endDay = parseInt(startDay) + 6 ;
    content.innerHTML = '<div> Showing data for days ' + startDay + ' to ' + endDay + '</div>';
  }, 1);
});


for(var i =0; i < slides.length; i++){
  slidesOffsets.push((slides[i].offsetLeft * -1) + 10);
}
	
swiper.on('sliderMove', function(e){
  currentOffset = this.translate;
		
  for(var i=0; i<slides.length; i++){
    if( slidesOffsets[i] <= currentOffset){				
      startIndex = i ;
      break;
    }
  }
		
  endIndex = startIndex + 6;
  content.innerHTML = '<div> Showing data for days ' + startIndex + ' to ' + endIndex +  '</div>';		
});
