<scroll-view scroll-y="true" bindscrolltolower="load" class="scroll-loading" style="height:{{windowHeight}}px;">

<view class="projectList" wx:for="{{projectList}}">

    view>
scroll-view>

loading:function () {
    var that = this;
    wx.request({
        method: 'GET',
        url: '',
        data: {
            offset: that.data.pageSize * (that.data.page - 1),
            limit: that.data.pageSize
        },
        header: {
            'content-type': 'application/json', // 默认值
        },
        success: function(res) {
            console.log(res.data);
            if (res.statusCode == 200) {
                if (that.data.page === 1) {
                    that.setData({
                        projectList:res.data
                    });
                } else {
                    var words = that.data.projectList.concat(res.data);
                    that.setData({
                        projectList: words
