Question

是否可以隐藏此表的结果并仅显示过滤后的结果？

<table class="table table-responsive" ng-class="{'table- 
striped':!spinnerVisible}">
                    <thead class="thead-inverse">
                        <tr>
                            <th><input type="checkbox" value="selected" ng- 
             model="checkboxes.checkAll" ng-click="checkAllRows()"></th>
                            <th>SID</th>
                            <th>Name</th>
                            <th>Pathway</th>
                            <th>Advisor</th>
                            <th>Credits</th>
                            <th>Campus</th>
                            <th ng-if="isPathwayLead">Action</th>
                        </tr>
                    </thead>
                    <tr ng-repeat="s in           
                   searchData.students|orderBy:'lastName' |filter:search | 
                   range:selectedPage:pageSize" student-row></tr>
                </table>

默认情况下，页面会加载这样的学生列表

我想隐藏此列表，仅显示上面过滤器的结果！有可能吗？

学生行

<tr ng-class="{awesome:s.selected}">
<td><input name="checker" type="checkbox" value="selected" ng-model="s.selected"></td>
<td><a class="clickableAwesomeFont" ng-click="toStudent(s.sid)">{{s.sid}}</a></td>
<td>{{s.lastName.trim() + ', ' + s.firstName}}</td>
<td>{{s.pathwayName + (s.subPathwayName ? ', ' + s.subPathwayName : '')}}</td>
<td>{{s.advisorName}}</td>
<td>{{s.credits}}</td>
<td>{{s.branchCodeDescription}}</td>
<td ng-if="isPathwayLead"><span class="card-title fa fa-pencil-square-o pull-right clickableAwesomeFont" ng-click="popupReviewForm(s)"></span></td>

SearchFilter

基本上只是想知道我是否可以使用ng-Show来显示过滤的结果并隐藏其余部分而无需更改很多内容

Answer 1

我正在分享我通常需要在网格列表中进行搜索的方式。通常，我将一个输入作为search term，并在$filter中借助watcher搜索整个列表，如果它与特定对象的任何键匹配，则更新网格列表立即使用新的过滤列表。

我不建议复制粘贴代码，因为我使用了许多自定义指令和材料设计。但是您可以获得主要的想法。

<md-toolbar style="background-color:#F57C00 !important;" ng-show="showSearch">
            <div class="md-toolbar-tools">
            <md-input-container class="md-block" flex-gt-sm>
                <md-icon style="color:white">search</md-icon>
                <input type="text" ng-model="searchPhrase" style="color:white" name="searchPhrase">
            </md-input-container>
            <md-button ng-click="resetFilter()" class="md-icon-button">
                <md-tooltip style="background-color:lightgray;color:black" md-direction="top">close</md-tooltip>
                <md-icon>close</md-icon>
            </md-button>
            </div>
        </md-toolbar>

在我的控制器中，我将观察者写为：

$scope.$watch('searchPhrase', function (keyword) {
            if (keyword!= null && keyword!= '' && keyword!= undefined)
                $scope.gridList = ($filter('filter')($scope.actualGridList, keyword)); 

            // incase keyword was empty, change the list back to original
            else 
                $scope.gridList = angular.copy($scope.actualGridList);
        });

//incase reset button was pressed, change the list back to original
    $scope.resetFilter = function () {
                $scope.showSearch = false;
                $scope.searchPhrase = '';
                $scope.gridList = angular.copy($scope.actualGridList);
            }

请注意：

我将gridlist用作ng-repeat列表而不是actualGridList，这样，我将保留原始列表不变，而gridList将被反映到原始列表通过我的resetFilter()

如果要基于许多关键字过滤searchData.students，则可以基于这些关键字过滤列表，类似于：

$scope.copStudents = $filter('filter')($scope.searchData.students, { 'name': keyword }, true);

AngularJS使用ng-repeat在表格中显示刚刚过滤的项目
