微信小程序---仿今日头条

weixinddemo

本demo主要调用了https://api.tianapi.com/social/的api接口，需要申请apikey，将其定义在app.js中，请求中的url格式为https://api.tianapi.com/social/?key=yourKey&num=10¤tPage=X

loadDataFromServer: function(){
var that = this;
that.changeLoadingStatus(false);
app.req(URL,{
key:app.globalData.apikey,
num:10,
page:currentPage,
},{
success:function(resp){
console.log(resp);
console.log("成功加载页数" + currentPage);
var tempData = resp.data.newslist;
var toViewId = currentPage % 2 ==0?         "top-id":"top-id2";
that.setData({
renderData: tempData,
toView: toViewId,
});
that.changeLoadingStatus(true);
}
});
},

每次上拉调用refresh函数：当前页面减一，下拉调用loadMore函数：当前页面加一，定义在index.js中：
refresh: function(e){
currentPage = currentPage>1? --currentPage:1;
this.loadDataFromServer();
},

loadMore: function(e){
++currentPage;
this.loadDataFromServer();
},

除此之外，需要注意的还有flash页面跳转到首页时的setTimeout函数：因为跳转到tabBar的页面中，所以不能用redirectTo和navigateTo，只能用swithTab：

var timestamp = new Date().getTime();
setTimeout(function(){
wx.switchTab({
url: '../index/index'
});
},duration*2.5);

<scroll-view scroll-y="true" style="height:100vh;" scroll-into-view="{{toView}}" upper-threshold="5"
lower-threshold="5" bindscrolltoupper="refresh" bindscrolltolower="loadMore">
