  //点击‘签到规则’,显示签到规则弹框
  showRule: function(e) {
    var that = this;
    that.setData({

    })
  },
  //点击‘x’，关闭规则弹框
  closeRule: function(e) {
    var that = this;
    that.setData({
      showRule: false
    })
  },
})

当signState 为true时，签到按钮只能点击一次，因为它控制button元素的disabled 属性。在实际项目中应该点击签到后，signState=true 。但是如果为了测试，可以将它设置为false，以便观测其它数据是否正常。

（1）当设置signState 为true时；

（1）当设置signState 为false时；

    缺失模块。
    1、请确保node版本大于6.2
    2、在博客根目录（注意不是yilia根目录）执行以下命令：
    npm i hexo-generator-json-content --save

    3、在根目录_config.yml里添加配置： 

      jsonContent:
    meta: false
    pages: false
    posts:
      title: true
      date: true
      path: true
