页面中调用
<page-directive total-count="param.page.totalCount" page-size="param.page.pageSize" param="param" page-itmes="param.selectCount" show-max-page="9" current-page="param.page.currentPage" go-page="queryList(param.page.currentPage)"></page-directive>
页面中获取数据的方法是queryList,go-page的时候把currentpage作为传递过去即可发送请求,取得想要的结果。
controller中需要传入初始化的数据
//初始化分页信息 $scope.param = { selectCount: [5, 10, 15], page: { currentPage: 1, pageSize: 5 } };
