主干分页

Question

谁能给我解释一下这个backbone.paginator示例是如何工作的？

https://github.com/backbone-paginator/backbone.paginator/blob/master/examples/request-paging/collections/PaginatedCollection.js

我看到可以使用以下URL到达后端：

paginator_core: {
  type: 'GET',
  dataType: 'jsonp',
  url: 'https://api.github.com/repos/twitter/bootstrap/issues?'
},

但是这个例子在什么地方传递了页码和从后端获取的itme数量呢？我的后端是通过以下restfull网址访问的:我不知道如何在上面的网址中插入下一页的详细信息…

www.test.com/getItems/{query}/{from}/{size}

这是由分页器插件自动插入的吗？

只需检查fetch方法的内部实现

 // map params except directions
      var queryParams = this.mode == "client" ?
        _pick(this.queryParams, "sortKey", "order") :
        _omit(_pick(this.queryParams, _keys(PageableProto.queryParams)),
              "directions");

      var i, kvp, k, v, kvps = _pairs(queryParams), thisCopy = _clone(this);
      for (i = 0; i < kvps.length; i++) {
        kvp = kvps[i], k = kvp[0], v = kvp[1];
        v = _isFunction(v) ? v.call(thisCopy) : v;
        if (state[k] != null && v != null) {
          data[v] = state[k];
        }
      }

基于以下条件创建请求

queryParams: {
  currentPage: "page",
  pageSize: "per_page",
  totalPages: "total_pages",
  totalRecords: "total_entries",
  sortKey: "sort_by",
  order: "order",
  directions: {
    "-1": "asc",
    "1": "desc"
  }
},

属性-因此，当前集合状态mapps超过了queryParams中各代url的设置
