微信小程序开发下拉刷新功能

1.在json页面配置：

{
  "enablePullDownRefresh": true
}

2.调用刷新函数

  onPullDownRefresh: function() {
    this.updateBlogs()
  },
updateBlogs: function () {
    var that = this
    wx.request({
      url: common.baseUrl + 'blog_rss.php',
      data: {
      },
      header: {
        'Content-Type': 'application/json'
      },
      success: function (res) {
        var feeds = feed.getBlogs(res.data);
        wx.setStorage({
          key: "blog_feeds",
          data: feeds
        })

        that.setData({
          feeds: feeds
        })
      }
    })
  },
