问题描述
我正在尝试使用下拉列表进行过滤并在 ng-repeat 中动态更改值，不确定如何执行操作，是否有任何提示?
I'm trying to filter using dropdown and change value dynamically in ng-repeat, not sure how to do it, any hints?
下拉菜单:
<label>Status</label>
<select class="form-control" ng-model="currentlySelected">
<option value="">All</option>
<option value="inactive">Inactive</option>
<option value="active">Active</option>
</select>
过滤条件:
filter disable for All results
filter: {deleted_at : ''} --> Inactive results
filter: {deleted_at : null} --> Active results
查看:
<tr ng-repeat="user in users">
推荐答案
您需要类似的内容，
<li ng-repeat="user in users | filter : {status: currentlySelected}: true">
演示
angular.module('app', [])
.controller('Main', ['$scope', function($scope) {
$scope.title = "Filter Based on Select Value";
$scope.users = [
{"id":18,"deleted_at" : ''},
{"id":19,"deleted_at":'null'},
{"id":21,"deleted_at":''},
{"id":22,"deleted_at":''},
]
}]);<!DOCTYPE html>
