• Decoration4:分页展示


    现在我们实现前台List的分页展示,这也是最基本的要求

    先看现在的Rest数据格式,在spring的默认返回中,分页用到的元素都已经在page节点中返回了,只要在前台合理利用就足够了

    {
      "links" : [ {
        "rel" : "self",
        "href" : "http://localhost:8080/coach"
      }, {
        "rel" : "profile",
        "href" : "http://localhost:8080/profile/coach"
      }, {
        "rel" : "search",
        "href" : "http://localhost:8080/coach/search"
      } ],
      "content" : [ {
        "id" : 1,
        "name" : "Jack",
        "password" : "Bauer",
        "age" : 10,
        "content" : [ ],
        "links" : [ {
          "rel" : "self",
          "href" : "http://localhost:8080/coach/1"
        }, {
          "rel" : "coach",
          "href" : "http://localhost:8080/coach/1"
        } ]
      }, {
        "id" : 2,
        "name" : "Chloe",
        "password" : "OBrian",
        "age" : 10,
        "content" : [ ],
        "links" : [ {
          "rel" : "self",
          "href" : "http://localhost:8080/coach/2"
        }, {
          "rel" : "coach",
          "href" : "http://localhost:8080/coach/2"
        } ]
      }],
      "page" : {
        "size" : 20,             -----这里是页面大小
        "totalElements" : 15,    -----这里是总行数
        "totalPages" : 1,        ----这里是总页数
        "number" : 0             ------这里是当前页
      }
    }

    1、spring-data-rest的分页请求url

    http://localhost:8080/coach?page=0&size=20

    2、接下来就是选型问题,到底该用哪一种分页插件呢

    (1)Smart-Table

    (2)ng-grid

    (3)自定义写法

    使用1/2两种都比较重量级,所以从GitHub上找了一个相对来说比较轻量级的插件angularjs-pagination,页面中引入ng-pagination.min.js、ng-pagination.min.css两个文件,在Controller中设置

    $scope.pageCount = data.page.totalPages;
    $scope.currentPage = data.page.number;
    
    $scope.onPageChange = function() {
            commonService.getPage($scope.currentPage - 1).then(function(data) {
                console.log("Get CoachList Success");
                $scope.coachs = data;
            }, function() {
                console.log("Get CoachList Error");
                $scope.errorMessage = 'Get CoachList Error';
            })
        };

    效果如下:

     这里想到一个遗留问题:第一次访问的时候能不能只查询第一页的内容,而不是上来就load完所有数据。
