初始化数据

data: {
    total_donate:\'0.00\',
    total_help:0,
    total_join:0,
}

获取数据函数

// 获取统计数据
statData:function() {
    let that = this; // this指当前的Page对象
    util.getData(\'statData\', {
      method: \'POST\'
    }, function (data) {
      if (data.errno == 0) {
          that.setData({
            total_donate: data.data.total_donate,
            total_help: data.data.total_help,
            total_join: data.data.total_join,
          });
      }
    })
}

在onLoad中加载数据

/**
 * 生命周期函数--监听页面加载
 */
onLoad: function (options) {
    let that = this;
    this.statData();
}
