@ firebase/database:用户回调抛出了异常.TypeError:无法读取未定义的属性"myID"
一旦我将我的应用程序构建到生产到Firebase托管中,我就会遇到一些用户的错误:
@ firebase/database:FIREBASE警告:用户回调抛出了异常.TypeError:无法读取未定义的属性"myID"

在我的代码中,在任何地方都没有变量"myID" .一切都可以很好地用于开发,但是一旦它被构建并在生产中,错误就会出现在某些用户身上.

Angular 6显示延迟加载模块的组件
我在使用Angular 6时从延迟加载的模块加载组件时遇到问题.
我使用CLI创建了一个库 -
ng generate library @org/chat
更新的angular.json文件包括:
"lazyModules": [
"dist/org/chat"
],
然后通过AppComponent成功加载模块:
constructor(private _injector: Injector, private loader: SystemJsNgModuleLoader, public dialog: MatDialog) {}
load() {
this.loader.load('dist/org/chat#ChatModule').then(moduleFactory => {
const moduleRef = moduleFactory.create(this._injector);
});
}
到目前为止一直很好,模块正在加载.
但是,ChatModule有一个名为ChatPopupComponent的组件,我找不到使用对话框(或通过将其添加到ViewChild容器)来显示它的方法.
要在对话框中打开组件,需要在模块的entryComponents下声明并在AppComponent级别导入:
let dialogRef = this.dialog.open(ChatPopupComponent
data: {}
});
但是当直接导入组件(并从库中导出)时,我得到以下(明显的)错误:' Component ChatPopupComponent is not part of any NgModule or the module has not been imported into your module'.由于它是一个延迟加载的模块,它显然还没有导入.
当我尝试以下内容时:
let name: any = 'ChatPopupComponent';
let dialogRef = this.dialog.open(name
data: {}
}); …推荐指数

Angular2验证错误为'ngClass',因为它不是'div'的已知属性.(
在这里我为EName验证编写了一个小的验证属性,当我尝试2加载Html页面时,我将错误视为'ngClass',因为它不是'div'的已知属性.(
Component.ts
import { Component, OnInit } from "@angular/core"
import { Employee } from "../../../templates/employee/employee"
import { Validators, FormGroup, FormBuilder } from "@angular/forms"
@Component({
selector: "customer-ui",
templateUrl: "../../../templates/customer/customer.html"
})
export class JamComponent implements OnInit {
EmpleoyeeForm: FormGroup;
public constructor(private fb: FormBuilder) {}
ngOnInit(): void {
this.EmpleoyeeForm = this.fb.group({
EmpName: ['', [Validators.required]]
})
}
Htmlcode
<form class="form-horizontal" novalidate [formGroup]="EmpleoyeeForm">
<fieldset>
<div class="form-group" [ngClass]="{'has-error': (EmpleoyeeForm.get('EmpName').touched ||
EmpleoyeeForm.get('EmpName').dirty) &&

当调用onlet of leaflet Marker时,Material Dialog会卡住
我有一个项目,我有一个地图(使用ngx-leaflet).
在点击一个标记,我想说明从对话框角材料.
对话框打开但是当我单击关闭按钮时,它会再次重新打开然后关闭.
我尝试了什么:
- 使用超时延迟对话框
- 触发打开对话框的主题
- 删除并创建新的Dialog
- 在ngx-leaflet和angular-material问题中搜索此错误
我发现了什么:
- 发生某些事情后触发所有生命周期钩子(点击,后面的js事件,任何事物)
- Dialog可以很简单,但不会改变任何东西
- 当我关闭时再次打开对话框(在AfterClosed of Dialog中)它正常工作
示例代码的进一步说明:

为任何浏览器定位div在中心和左右的位置(跨浏览器)
Three div panels:-
1) (div-B) one div with max-width = 500px and min-width=400px should always on
the center of all browsers.
2) (div-A) one div should show and hide on the left of (div-B) having min-width
= 200px and max-width= 300px;
3) (div-C) one div should show and hide on the right of (div-B) having min-width
= 200px and max-width= 300px;
div-A和div-C的show和Hide应该是这样的,它不应该从它的位置移动div-B,但是,它可以达到它的最大宽度和最小宽度.div-B应始终位于所有浏览器的中心.

如何使用 CloudFormation 创建此 DynamoDb 表组？
我们可以从 AWS 控制台创建、编辑、删除组，以维护 DynamoDb 表的逻辑分组。我搜索了 AWS 文档和论坛，但没有找到有关如何使用 CloudFormation 创建此 DynamoDb 表组或如何使用 AWS .NET SDK 在组内创建表的方法。这甚至可能吗？
