Twitch Streamers实现

Posted by jjx on November 4, 2016

Twitch Streamers主要实现了以下功能

  • 根据api获取twitter好友数据并展示
  • 根据在线与离线状态可以切换效果
  • 根据页面大小，布局会自动变化

注意：当界面压缩时，行高会变为原来的一半，正好原先并列的变成两行，与图标对齐

main.js
点击时会将hidden属性添加或移除到控件上，以实现点击的转换

var channels = ["ESL_SC2", "OgamingSC2", "cretetion", "freecodecamp", "storbeck", "habathcx", "RobotCaleb", "noobs2ninjas"];

function getChannelInfo() {
    channels.forEach(function(channel) {

        };
        $.getJSON(makeURL("streams", channel), function(data) {

                status;
