问题描述

限时送ChatGPT账号..

我正在尝试使用 uib-pagination 在我的 Angular 应用程序中保持分页.我无法找到正确的方法来做到这一点.

HTML

<头><tr class="table-head"><th>姓名</th></tr></thead><tr ng-repeat="候选人中的人"><th><div>{{person}}</div></th></tr></tbody>

控制器

$scope.totalItems = $scope.aCandidates.length;$scope.currentPage = 1;$scope.itemsPerPage = 10;

我能够看到分页栏，但没有执行任何操作，即使将总项目数设为 10，也会呈现整个表格数据.

uib-pagination 的工作原理以及数据(在本例中为 aCandidates)如何链接到分页.

解决方案

你缺少的部分是你必须有一个函数来从你的整个数组中获取当前页面的数据.我添加了一个名为 setPagingData() 的函数来处理这个问题.

您可以在分叉的 plunker

中看到这一点

var app = angular.module("plunker", ["ui.bootstrap"]);app.controller("MainCtrl", function($scope) {var allCandidates =[姓名1"、姓名2"、姓名3"、姓名4"、姓名5"、"name6", "name7", "name8", "name9", "name10","name11", "name12", "name13", "name14", "name15",name16"、name17"、name18"、name19"、name20"];$scope.totalItems = allCandidates.length;$scope.currentPage = 1;$scope.itemsPerPage = 5;$scope.$watch("currentPage", function() {setPagingData($scope.currentPage);});函数 setPagingData(page) {var pagedData = allCandidates.slice((page - 1) * $scope.itemsPerPage,页 * $scope.itemsPerPage);$scope.aCandidates = pagedData;}});

<link data-require="bootstrap-css@*" data-semver="4.0.0-alpha.2" rel="样式表" href="https://maxcdn.bootstrapcdn/bootstrap/4.0.0-alpha.2/css/bootstrap.min.css"/><script>document.write('<base href="' + document.location + '"/>');</script><script data-require="angular.js@1.4.x" src="https://code.angularjs/1.4.9/angular.js" data-semver="1.4.9"></脚本><script data-require="ui-bootstrap@*" data-semver="1.3.2" src="https://cdn.rawgit/angular-ui/bootstrap/gh-pages/ui-bootstrap-tpls-1.3.2.js"></script><div ng-app="plunker"><div ng-controller="MainCtrl"><table id="mytable" class="table table-striped"><头><tr class="table-head"><th>姓名</th></tr></thead><tr ng-repeat="候选人中的人"><th><div>{{person}}</div></th></tr></tbody><uib-pagination total-items="totalItems" ng-model="currentPage" items-per-page="itemsPerPage"></uib-pagination>

I am trying to keep pagination in my Angular application using uib-pagination. I am unable to get proper way to do this.

HTML

<table id="mytable" class="table table-striped">
  <thead>
    <tr class="table-head">
      <th>Name</th>
    </tr>
  </thead>
  <tbody>
    <tr ng-repeat="person in aCandidates">
      <th>
        <div>{{person}}</div>
      </th>
    </tr>
  </tbody>
</table>

Controller

$scope.totalItems = $scope.aCandidates.length;
$scope.currentPage = 1;
$scope.itemsPerPage = 10;

I am able to see the pagination bar but no action is performed with that and the entire table data is rendered even after giving total-items as 10.

How exactly uib-pagination works and how is the data (in this case aCandidates) is linked to pagination.

解决方案

The part you are missing is that you have to have a function to get the current page's data from your entire array. I've added a function called setPagingData() to handle this.

You can see this in the forked plunker

var app = angular.module("plunker", ["ui.bootstrap"]);

app.controller("MainCtrl", function($scope) {
  var allCandidates =
      ["name1", "name2", "name3", "name4", "name5",
       "name6", "name7", "name8", "name9", "name10",
       "name11", "name12", "name13", "name14", "name15",
       "name16", "name17", "name18", "name19", "name20"
      ];

  $scope.totalItems = allCandidates.length;
  $scope.currentPage = 1;
  $scope.itemsPerPage = 5;

  $scope.$watch("currentPage", function() {
    setPagingData($scope.currentPage);
  });

  function setPagingData(page) {
    var pagedData = allCandidates.slice(
      (page - 1) * $scope.itemsPerPage,
      page * $scope.itemsPerPage
    );
    $scope.aCandidates = pagedData;
  }
});

<link data-require="bootstrap-css@*" data-semver="4.0.0-alpha.2" rel="stylesheet" href="https://maxcdn.bootstrapcdn/bootstrap/4.0.0-alpha.2/css/bootstrap.min.css" />
<script>document.write('<base href="' + document.location + '" />');</script>
<script data-require="angular.js@1.4.x" src="https://code.angularjs/1.4.9/angular.js" data-semver="1.4.9"></script>
<script data-require="ui-bootstrap@*" data-semver="1.3.2" src="https://cdn.rawgit/angular-ui/bootstrap/gh-pages/ui-bootstrap-tpls-1.3.2.js"></script>

<div ng-app="plunker">
  <div ng-controller="MainCtrl">
    <table id="mytable" class="table table-striped">
      <thead>
        <tr class="table-head">
          <th>Name</th>
        </tr>
      </thead>
      <tbody>
        <tr ng-repeat="person in aCandidates">
          <th>
            <div>{{person}}</div>
          </th>
        </tr>
      </tbody>
    </table>
    <uib-pagination total-items="totalItems" ng-model="currentPage" items-per-page="itemsPerPage"></uib-pagination>
  </div>
</div>
