Question

我使用ui-bootstrap分页，我使用$ index值在每一行上添加注释它正常工作但在第二页和第三页依此类推$ index value再次从0开始。如何读取第2个第3页上的索引值，

为什么它在第2页再次从第0个索引开始，依此类推。我也在textarea中传递索引值。

我在下面给出了代码。

Answer 1

$index实际上是可见元素的索引。你可以得到这样的真实指数。

index += ($scope.currentPage - 1) * $scope.itemsPerPage;

Answer 2

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

app.controller("MainCtrl", function($scope) {
  var allData =
      [your data goes here];

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

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

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