我在块内有一些复选框:
<div ng-show="searchIn.IS" class="filterContent">
<div ng-click="toggleFilter('IS')">
<span class="{{filters.IS}}FilterIcon"></span>
Information System :
</div>
<div ng-show="filters.IS">
<md-checkbox ng-repeat="IS in ISList" ng-click="setISSearch(IS)" ng-checked="isInISSearch(IS)">
{IS}}
</md-checkbox>
</div>
</div>
<br />
<div ng-show="searchIn.area" class="filterContent">
<div ng-click="toggleFilter('area')">
<span class="{{filters.area}}FilterIcon"></span>
Area :
</div>
<div ng-show="filters.area">
<md-checkbox ng-repeat="area in filterAreaList" ng-click="setAreaSearch(area)" ng-checked="isInAreaSearch(area)" ng-show="isInCurrentAreas(area)">
{{area}}
</md-checkbox>
</div>
</div>
所以,每次我检查或取消选中ISList块中的复选框时,都会更改filterAreaList
。但视图未更新,所有区域仍然显示。
我还尝试了ng-if
而不是ng-show
。
$scope.filterAreaList = [];
$scope.getAreaFilters = function () {
$scope.searchedIS = $scope.ISList.slice();
for (var i = $scope.searchedIS.length; i >= 0; i--) {
if ($scope.searched.IS.indexOf($scope.searchedIS[i]) === -1)
$scope.searchedIS.splice(i, 1);
}
for (var i = 0; i < $scope.areaList.length; i++) {
for (var j = 0; j < $scope.searchedIS.length; j++)
if ($scope.hasArea($scope.searchedIS[j], $scope.areaList[i]))
$scope.filterAreaList.push($scope.areaList[i]);
}
};
$scope.isInCurrentAreas = function (area) {
if ($scope.filterAreaList.indexOf(area) === -1)
return false;
return true;
};

但我真的没有看到如何将这个应用到我的案例中。
答案 0 :(得分:1)
嗯,我实际上错过了一些事情:
为了使其有效,我在$scope.filterAreaList = [];
函数中添加了getAreaFilters()
,并在getAreaFilters()
setAreaSearch(area)
就是这样。
