scrollview - 著名的 : scrollview within scrollview

Question

我正在尝试创建一个类似于 BBC 新闻 native 应用程序的布局(使用known.js)；一个垂直的ScrollView，其中有许多水平的ScrollView。我已经“工作”到了一切都渲染并且水平滚动条完美工作的程度。我的问题是，如果用户在水平 ScrollView 内滑动表面，则垂直滚动事件不会触发。如果我触摸水平滚动条之外的区域，垂直滚动条将完成其工作并滚动...垂直

有人知道我错过了什么吗？我有一种感觉，可能需要一个 RenderNode，但到目前为止还没有运气。我刚刚开始接触 Famous。到目前为止我所看到的令人惊奇，但无法弄清楚这一点真的让我很困扰......

如果有人可以提供帮助，优步提前致谢...

我看到你已经弄清楚了，但我想我应该为任何需要起点的人发布一个干净的工作示例..所以这里是..

要回答这个问题，是的，您需要将事件从表面传输到每个 ScrollView

var Engine              = require("famous/core/Engine");
var Surface             = require("famous/core/Surface");
var View                = require("famous/core/View");
var Scrollview          = require("famous/views/Scrollview");
var ContainerSurface    = require("famous/surfaces/ContainerSurface");

var context = Engine.createContext();

var surfaces1 = [];
var surfaces2 = [];

var scrollers = [];

scroll_v_cont = new ContainerSurface({
    size:[300,300],
    properties: { overflow: 'hidden' }
});

var scroll_v = new Scrollview({ direction: 1 });

scroll_v.sequenceFrom(scrollers);

scroll_v_cont.add(scroll_v);

var scroll_h1_cont = new ContainerSurface({
    size:[300,300],
    properties: {overflow: 'hidden'}
});


var scroll_h1 = new Scrollview({ direction: 0});

scroll_h1.sequenceFrom(surfaces1);

scroll_h1_cont.add(scroll_h1);


var scroll_h2_cont = new ContainerSurface({
    size:[300,300],
    properties: { overflow: 'hidden'}
})


var scroll_h2 = new Scrollview({ direction: 0})

scroll_h2.sequenceFrom(surfaces2);

scroll_h2_cont.add(scroll_h2);

scrollers.push(scroll_h1_cont);
scrollers.push(scroll_h2_cont);

for (var i = 0; i < 4; i++) {
    var surface1 = new Surface({
         content: "Surface: " + (i + 1),
         size: [300, 300],
         properties: {
             backgroundColor: "hsl(" + (i * 360 / 8) + ", 100%, 50%)",
             lineHeight: "200px",
             textAlign: "center"
         }
    });

    surface1.pipe(scroll_v);
    surface1.pipe(scroll_h1);
    surfaces1.push(surface1);

    var surface2 = new Surface({
         content: "Surface: " + (i + 1),
         size: [300, 300],
         properties: {
             backgroundColor: "hsl(" + (i * 360 / 8 + (360 / 8)*4) + ", 100%, 50%)",
             lineHeight: "200px",
             textAlign: "center"
         }
    });

    surface2.pipe(scroll_v);
    surface2.pipe(scroll_h2);
    surfaces2.push(surface2);

};

context.add(scroll_v_cont);
