Html代码:这是html代码,基本上显示了一个带有搜索过滤器的表。 。 。
<input type="search" ng-model="search.$" />
<table class="table table-striped table-bordered">
<thead>
<tr>
<th><a href="#" ng-click="changeSort('name')">User</a></th>
<th><a href="#" ng-click="changeSort('contentType')">Content Type</a></th>
<th><a href="#" ng-click="changeSort('contentName')">Content Name</a></th>
<th><a href="#" ng-click="changeSort('startTime')">Start Time</a></th>
<th><a href="#" ng-click="changeSort('endTime')">End Time</a></th>
<th><a href="#" ng-click="changeSort('duration')">Duration(In Secs)</a></th>
</tr>
</thead>
<tbody>
<tr ng-repeat="record in records
| filter: search
| offset: currentPage*itemsPerPage
| limitTo: itemsPerPage
| orderBy:sort:reverse track by $index">
<td>{{record.user}}</td>
<td>{{record.contentType}}</td>
<td>{{record.contentName}}</td>
<td>{{record.startTime}}</td>
<td>{{record.endTime}}</td>
<td>{{record.duration}}</td>
</tr>
</tbody>
<tfoot>
<td colspan="6">
<div class="pagination pull-right">
<ul>
<li ng-class="prevPageDisabled()"><a href
ng-click="prevPage()">« Prev</a></li>
<li ng-repeat="n in range()"
ng-class="{active: n == currentPage}" ng-click="setPage(n)">
<a href="#">{{n+1}}</a>
</li>
<li ng-class="nextPageDisabled()"><a href
ng-click="nextPage()">Next »</a></li>
</ul>
</div>
</td>
</tfoot>
</table>
Angular Js代码:这是使用whtch搜索,排序和分页的角度代码。 。
angular.module("contentViewStatusApp").controller("contentViewStatusController", function($scope, contentViewStatusService)
{
$scope.records = contentViewStatusService.list();
$scope.changeSort = function(value)
{
if ($scope.sort == value)
{
$scope.reverse = !$scope.reverse;
return;
}
$scope.sort = value;
$scope.reverse = false;
}
$scope.itemsPerPage = 8;
$scope.currentPage = 0;
$scope.items = [];
$scope.range = function()
{
var rangeSize = 5;
var ret = [];
var start;
start = $scope.currentPage;
if (start > $scope.pageCount() - rangeSize)
{
start = $scope.pageCount() - rangeSize + 1;
}
for (var i = start; i < start + rangeSize; i++)
{
ret.push(i);
}
return ret;
};
$scope.prevPage = function()
{
if ($scope.currentPage > 0)
{
$scope.currentPage--;
}
};
$scope.prevPageDisabled = function()
{
return $scope.currentPage === 0 ? "disabled" : "";
};
$scope.pageCount = function()
{
return Math.ceil($scope.records.length / $scope.itemsPerPage) - 1;
};
$scope.nextPage = function()
{
if ($scope.currentPage < $scope.pageCount())
{
$scope.currentPage++;
}
};
$scope.nextPageDisabled = function()
{
return $scope.currentPage === $scope.pageCount() ? "disabled" : "";
};
$scope.setPage = function(n)
{
$scope.currentPage = n;
};
});
angular.module("contentViewStatusApp").filter('offset', function()
{
return function(input, start)
{
start = parseInt(start, 10);
return input.slice(start);
};
});
我在这里遇到的唯一问题是,在搜索记录数量减少后,分页不会更新,任何帮助都非常感谢,提前感谢。 。

记录数组中的项目数永远不会更改,因为过滤器返回一个新数组,而不是源数组的更新版本。因此,pageCount也不会改变;为了解决这个问题,有两种可能的解决方案:
解决此问题的最简单方法可能是以编程方式过滤您控制器中的数据。假设您将$ filter服务传递给控制器,您可以编写一个函数:
$ scope.getFilteredRecords = function(){ var filterBy = $ filter(&#39; filter&#39;); return filterBy($ scope.records,$ scope.search); }
然后在查看器和pageCount()中使用getFilteredRecords()而不是记录;这是最简单的方法,但会做多个冗余过滤器;如果您有大量数据,这可能是性能问题
实现类似结果的更有效方法是使用$ watch服务,该服务会在给定变量更改值时进行检查。因此,您可以在$ scope.search中查看任何更改,填充已过滤的辅助变量并使用它而不是记录: 在控制器的某个地方(但不在函数内),注册你的$ watch:
var filterBy = $ filter(&#39; filter&#39;); $ scope。$ watch(&#39; search&#39;,function(newValue){ $ scope.filtered = filterBy($ scope.records,newValue); },true);
更新您的观点:
<tr ng-repeat="record in filtered
| offset: currentPage*itemsPerPage
| limitTo: itemsPerPage
| orderBy:sort:reverse track by $index">
(你不再需要过滤器,因为$ watch会照顾它)
更新pageCount:
$scope.pageCount = function()
{
return Math.ceil($scope.filtered.length / $scope.itemsPerPage) - 1;
};
