我有重复列表,我需要用复选框过滤该列表。在复选框中我有三个值,ERROR,WARNING,SUCCESS。如果我检查ERROR,只显示错误,如果我检查ERROR和WARNING显示错误和警告,同样成功。但问题是,当我检查ERROR框时,列表只显示有错误的数据,但是当我检查WARNING时,它们会显示列表中的所有数据,而不仅是ERROR和WARNING数据。为了更好地解释这里是

这是因为您的toggleFilter()
功能
$scope.toggleFilter= function(filterValues) {
if ($scope.filterValue == undefined) {
$scope.filterValue = filterValues;
} else {
delete $scope.filterValue;
}
};
做什么:
因此,当您检查ERROR时,它会将ERROR设置为过滤器,但是当您单击“警告”时,它会触发else
,并删除当前选择。
将else
更改为:
else {
delete $scope.filterValue;
console.log($scope.filterValue);
}
当选择多个过滤器时,您可以看到它undefined
。

因为没有任何解决方案,这是我的代码如何解决这个问题。
<div class="nav">
<div ng-repeat="filter in filters" ng-class="{sel: selection.indexOf(filterValue) == selected}">
<span class="filters_ct_status"></span>
<div ng-repeat="filterValue in filter.lists" style="float:left; padding: 5px">
<input type="checkbox" value="{{filterValue}}" ng-model="checked" ng-checked="selection.indexOf(filterValue) > -1" ng-click="toggleSelection(filterValue)">
<img ng-if="filterValue == 'Success'" src="assets/img/success.png" alt="success"/>
<img ng-if="filterValue == 'Warning'" src="assets/img/warning.png" alt="warning"/>
<img ng-if="filterValue == 'Error'" src="assets/img/error.png" alt="Error"/>
</div>
</div>
</div>
<div class="table_bench_info logBox" style="overflow-y: auto; height: 250px;">
<div class="list" ng-repeat="list in lists">
<span ng-if="listaFiltera.indexOf(list.class) !== -1">{{list.description}}</span>
</div>
</div>
并且有控制器
$scope.filterValue = [];
// toggle selection for a given employee by name
$scope.toggleSelection = function(valueFilter) {
var idx = $scope.filterValue.indexOf(valueFilter);
if (idx > -1) {
$scope.filterValue.splice(idx, 1);
if($scope.filterValue.length == 0){
return $scope.listaFiltera = ['Error','Warning','Success'];
}else{
$scope.listaFiltera = $scope.filterValue.map(function(x) {
return x;
});
}
} else {
$scope.filterValue.push(valueFilter);
$scope.listaFiltera = $scope.filterValue.map(function(x) {
return x;
});
}
};
$scope.filters = [
{
lists: ['Error','Warning','Success']
}
];
我们需要对数组进行推送复选框。并从数组中拼接未选中的复选框。另外,如果我们想要多个过滤器,我们需要检查$ scope.filterValue.length。
