    自动翻页规则
    type：
      1 = 脚本实现自动无缝翻页
      2 = 网站自带了自动无缝翻页功能，只需要点击下一页按钮即可，这时 nextText 为按钮文本，避免一瞬间加载太多次下一页
      3 = 依靠元素距离可视区域底部的距离来触发翻页
    HT_insert：
      1 = 插入该元素本身的前面；
      2 = 插入该元素当中，第一个子元素前面；
      3 = 插入该元素当中，最后一个子元素后面；
      4 = 插入该元素本身的后面；
    scrollDelta：数值越大，滚动条触发点越靠上（越早开始翻页），一般是访问网页速度越慢，该值就需要越大
    function：
      before = 插入前执行函数；
      after = 插入后执行函数；
      parameter = 参数
