我正在使用md select rendering md checkbox wiyth a selectAll选项。
如果我选择全部,所有复选框都会被选中,下拉列表会关闭。
如果选择了除“全部”以外的任何值并单击“外部”将其关闭,如何触发不关闭下拉列表?
var app = angular.module('BlankApp', ['ngMaterial', 'ngMessages']);
app.controller('mdSelectController', function($scope, $mdPanel, $mdSidenav, $mdDialog) {
$scope.helpers = [{
name: 'All',
selected: false
},
{
name: 'Ron',
selected: false
},
{
name: 'Jim',
selected: false
},
{
name: 'John',
selected: false
},
{
name: 'Paul',
selected: false
},
{
name: 'Jeremie',
selected: false
}
];
$scope.changeCheckbox = function(rating) {
console.log(rating)
if (rating.name === 'All' && rating.selected === true) {
_.forEach($scope.helpers, function(item) {
item.selected = true;
});
}
if (rating.name === 'All' && rating.selected === false) {
_.forEach($scope.helpers, function(item) {
item.selected = false;
});
}
if (rating.name !== 'All') {
console.log("Not all");
_.forEach($scope.helpers, function(item) {
if (item.name === 'All') {
item.selected = false;
}
});
}
};
});

<md-input-container>
<label>Rating</label>
<md-select id="ratingDropdown" ng-model="automationRatingObj" md-container-class="ratingDropdown" required="required">
<md-option ng-value="rating" ng-repeat="rating in helpers track by $index">
<md-checkbox ng-model="rating.selected" aria-label="Select a Rating" ng-change="changeCheckbox(rating)"></md-checkbox>{{rating.name}}
</md-option>
</md-select>

请给我建议。我检查了mdselect的API,但是他们没有任何代码来保持下拉列表的打开。另外,如何禁用md select中的文本并启用click only for复选框?
