【问题描述】：
我正在使用 AngularJS 1.6 和 Angular Material 我有一个 md-autocomplete 曾经工作得很好，但是在我把它放在 md-dialog 框中，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，我无法填写输入内容。（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、焦点和键位上执行 event.stopPropagation()，但没有帮助。 我想了一会儿，两个控制器的作用域是冲突的，所以我删除了两个作用域之间的链接，它没有帮助。我搜索了一下，似乎以前没有人遇到过这个。
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：我通过了范围来保留数据，我认为这是问题所在，所以我删除了它，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();
}
}
这里是html模板：
<md-dialog class="dialogSuccess" aria-label="Add Groups To Job">
<md-toolbar>
<div class="md-toolbar-tools">
<h2>Add Groups To Job</h2>
<span flex></span>
<md-button class="md-icon-button" ng-click="AddAuthDialog.cancelDialog()">
<md-icon class="closeIcon" md-font-icon="mdi mdi-close" aria-label="Close dialog"></md-icon>
</md-button>
</div>
</md-toolbar>
<md-content layout="column" flex ng-cloak>
<div class="md-dialog-content">
<form>
<md-autocomplete flex
md-input-name="autocompleteField"
md-input-minlength="0"
md-input-maxlength="18"
md-no-cache="true"
md-selected-item="AddAuthDialog.selectedItem"
md-search-text="AddAuthDialog.searchTxt"
md-items="item in AddAuthDialog.querySearch(AddAuthDialog.searchTxt,AddAuthDialog.jobsToSearch)"
md-item-text="item.display"
md-floating-label="Jobs">
<md-item-template>
<span md-highlight-text="AddAuthDialog.searchTxt">{{item.display}}</span>
</md-item-template>
<md-not-found>Job "{{AddAuthDialog.searchTxt}}" not found </md-not-found>
</md-autocomplete>
<md-autocomplete flex
md-input-name="autocompleteFieldAD"
md-input-minlength="3"
md-input-maxlength="18"
md-no-cache="true"
md-selected-item="AddAuthDialog.selectedItemAD"
md-search-text="AddAuthDialog.searchTxtAD"
md-items="i in AddAuthDialog.querySearch(AddAuthDialog.searchTxtAD,AddAuthDialog.grpsToSearch)"
md-item-text="i.display"
md-floating-label="AD Groups">
<md-item-template>
<span md-highlight-text="AddAuthDialog.searchTxtAD">{{i.display}}</span>
</md-item-template>
<md-not-found>Job "{{AddAuthDialog.searchTxtAD}}" not found </md-not-found>
</md-autocomplete>
</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 消息显示在无效消息元素上调用的动画：JQLite [md-input-container.ng-scope.md-input-focused.md-input-has-value.ng-animate.md-input-invalid]
然后我将其删除以放置一个占位符，但行为没有改变。 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，如果我取消焦点按钮，页面上的每个事件都不再触发。
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>
