md-dialog 中的 md-autocomplete 在点击时失去焦点

md-autocomplete in md-dialog loses focus onclick

我正在使用 AngularJS 1.6 和 Angular Material 我有一个 md-autocomplete 曾经工作得很好,但在我把它放进去之后一个 md-dialog 框,它不再那么好用了。每当我点击自动完成字段时,焦点立即消失,我无法填写输入。(或者你必须非常快才能在焦点消失之前写一封信)。

我尝试在点击、聚焦和按键时执行 event.stopPropagation() 但它没有帮助。 我想了一下,两个控制器的范围是冲突的,所以我删除了两个范围之间的 link,但没有帮助。我搜索了一下,之前似乎没有人遇到过这个。

这是触发 md-dialog 的代码:

    public showAddAuthDialog(ev: any) {

        this.$mdDialog.show({
            controller: AddJobAuthDialogController,
            controllerAs: "AddAuthDialog",
            templateUrl: 'public/app/views/dialogs/addAuthDialog.html',                
            targetEvent: ev,                
            clickOutsideToClose: true,
            fullscreen: this.customFullscreen,
            scope: this.$scope,
            preserveScope:true            
        });
    }    

注意:我通过范围来保留数据,我认为这是问题所在所以我删除了它并且没有任何改变。

这是对话框控制器的代码:

     export class AddJobAuthDialogController {
         static $inject = ['$scope','$mdDialog',
              '$timeout',
                '$q',
                 'jobService'];
         public simulateQuery: boolean;
         public selectedItem: any;
         public selectedItemId: string;
         public searchTxt: string;      
         public jobsToSearch: any;            
         public selectedItemAD: any;
         public searchTxtAD: string;            
         public grpsToSearch: any;
         public customFullscreen = false;



    constructor(public $scope: any,
        public $mdDialog: any,
        public $timeout: any,
        public $q: any,
        public jobService: jobs.IJobService) {

        this.simulateQuery = true;
        this.selectedItem = null;
        this.searchTxt = null;
        this.selectedItemAD = null;
        this.searchTxtAD = null;

        this.jobsToSearch = this.$scope.Administration.jobsToSearch;
        this.grpsToSearch = this.$scope.Administration.grpsToSearch;

    }

    public $onChanges(changes) {
        if (changes.selectedItem) {
            this.selectedItem = changes.selectedItem.currentValue;
        }
        if (changes.jobsToSearch) {
            this.jobsToSearch = changes.jobsToSearch.currentValue;
        }
        if (changes.selectedItemId) {
            this.selectedItemId = changes.selectedItemId.currentValue;
        }
        if (changes.grpsToSearch) {
            this.grpsToSearch = changes.grpsToSearch.currentValue;
        }
    }

    public sendForm(event: any) {
        this.jobService.saveNewEntry(this.selectedItem.value, this.selectedItemAD.value).then((d) => {
            console.log(d);
            if (d.data == -1)
                this.showError(event);
            else
                this.showSuccess(event);
        });
    }

    public showSuccess(ev: any) {
        this.$mdDialog.show({
            controller: InsertDialogController,
            controllerAs: "InsertDialog",
            templateUrl: 'public/app/views/dialogs/adminInsertSuccessDialog.html',
            parent: angular.element(document.body),
            targetEvent: ev,
            clickOutsideToClose: true,
            fullscreen: this.customFullscreen // Only for -xs, -sm breakpoints.
        });
    };

    public showError(ev: any) {
        this.$mdDialog.show({
            controller: InsertDialogController,
            controllerAs: "InsertDialog",
            templateUrl: 'public/app/views/dialogs/adminInsertFailDialog.html',
            parent: angular.element(document.body),
            targetEvent: ev,
            clickOutsideToClose: true,
            fullscreen: this.customFullscreen // Only for -xs, -sm breakpoints.
        });
    };

    public querySearch(query, objectToSearch) {
        var results = query ? objectToSearch.filter(this.createFilterFor(query)) : objectToSearch,
            deferred;
        if (this.simulateQuery) {
            deferred = this.$q.defer();
            this.$timeout(function () { deferred.resolve(results); }, Math.random() * 1000, false);
            return deferred.promise;
        } else {
            return results;
        }
    }

    public createFilterFor(query) {
        var lowercaseQuery = angular.lowercase(query);
        return (res) => {
            return (angular.lowercase(res.display).indexOf(lowercaseQuery) !== -1);
        };
    }

    public cancelDialog() {
        this.$mdDialog.cancel();
    }
}

这是 html 模板:

            </form>
        </div>
    </md-content>


<md-dialog-actions>
    <md-button class="md-raised md-primary md-hue-1" ng-click="AddAuthDialog.sendForm()">Add</md-button>
</md-dialog-actions>

 </md-dialog>

注意: 有那么一刻我认为问题出在浮动标签上,因为我的控制台中有以下警告:

mdInput messages show animation called on invalid messages element: JQLite [md-input-container.ng-scope.md-input-focused.md-input-has-value.ng-animate.md-input-invalid]

然后我删除了它以放置一个占位符,但行为没有改变。 有什么问题可能来自哪里?

更新:

似乎焦点丢失了,因为它重新聚焦在已单击的按钮上,如果我取消聚焦按钮,页面上的每个事件都不会再触发。

这是按钮的 html 代码:

      <div class="fab-container" layout="row" layout-align="end end">
    <md-fab-speed-dial md-open="false" md-direction="up"
                       ng-class="md-fling">
        <md-fab-trigger ng-click="Administration.showAddAuthDialog($event)" ng-focus="false">
            <md-button aria-label="menu" class="md-fab md-accent">
                <md-icon class="mdi mdi-plus fab-button-icon"></md-icon>
            </md-button>
        </md-fab-trigger>          
    </md-fab-speed-dial>
</div>

问题似乎出在 md-fab-speed-dial,不知为何,它始终处于焦点状态。 我只是用一个简单的按钮替换了整个东西,现在它工作得很好。

新 html :

    <div layout="row" layout-align="end end">       
            <md-button  ng-click="Administration.showAddAuthDialog($event)" aria-label="menu" class="md-fab md-accent">
                <md-icon class="mdi mdi-plus fab-button-icon"></md-icon>                    
            </md-button>          
</div>
