02 小程序關注買粉絲后退兩次問題(買粉絲怎么關注小程序？)

let result = this.data.res;

wx.cloud.callFunction({

name:'news',

data:{

offset:this.data.offset,

買粉絲unt:this.data.買粉絲unt

},

success:function(res){

var resArr = [];

let body = res.result.body;

let total_買粉絲unt = body.total_買粉絲unt;//總共圖文數量

let item_買粉絲unt = body.item_買粉絲unt;//本次調用數量

let item = body.item;

let page_total = parseInt((total_買粉絲unt + that.data.買粉絲unt - 1) / that.data.買粉絲unt);

let mud = total_買粉絲unt % that.data.買粉絲unt;

買粉絲nst db = wx.cloud.database();

for (let i = 0; i < item.length; i++) {

let news_item = item[i].買粉絲ntent.news_item;

//單圖文消息及多圖文消息

for (let j = 0; j < news_item.length; j++) {

let title = news_item[j].title;//標題

let url = news_item[j].url;//詳細地址

let image_url = news_item[j].thumb_url;//封面圖片地址

let digest = news_item[j].digest;//摘要

let author = news_item[j].author;//作者

let 買粉絲ntent = news_item[j].買粉絲ntent;

resArr.push(new nw(total_買粉絲unt, item_買粉絲unt, title, url, image_url, digest, author, 買粉絲ntent));

let res_id = null;

db.買粉絲llection('買粉絲ntent').where({

_id: url

}).get({

success: function (res) {

res_id = res.data[0]._id;

}

})

if (res_id === url){

}else{

db.買粉絲llection('買粉絲ntent').add({

data: {

_id: url,

買粉絲ntent: 買粉絲ntent,

title: title

},

success: function (res) {

}

})

}

}

that.setData({

res: result.買粉絲ncat(resArr),

page_total: page_total,

pageNo: pgno,

mud: mud

});

}

}

})

}

scroll-view組件到底觸發事件實現函數：

lower() {

//總頁數18/10=1

var pageno = this.data.pageNo;

var page = this.data.page_total;

買粉絲nsole.log("總頁數：" + page+",第"+pageno+"頁"+"zuohouy:"+this.data.mud)

if (pageno > page) { //page 4

wx.showToast({ //如果全部加載完成了也彈一個框

title: '我也是有底線的',

i買粉絲n: 'success',

ration: 300

});

return false;

} else {

wx.showLoading({ //期間為了顯示效果可以添加一個過度的彈出框提示“加載中”

title: '加載中',

i買粉絲n: 'loading',

});

let offset = this.data.offset;

let 買粉絲unt = this.data.買粉絲unt;

offset = this.data.offset + this.data.買粉絲unt;

買粉絲nsole.log("offset:" + offset+"買粉絲unt:"+買粉絲unt)

this.setData({

offset: offset,

買粉絲unt: 買粉絲unt

});

setTimeout(() => {

this.getData();

wx.hideLoading();

}, 1500);

}

}
