如何使用量角器复制特定文本？

我想用此命令加载要粘贴的文本:

return browser.actions().sendKeys(Keys.CONTROL, 'v').perform();

样品:

加载我的文本"test",然后使用此命令粘贴"test"

我想在剪贴板中放一个文字

如何在Chrome上使用MAC上的量角器进行复制和粘贴？

newInput.sendKeys(protractor.Key.chord(browser.controlKey, "a"));
newInput.sendKeys(protractor.Key.chord(browser.controlKey, "c"));
newInput.sendKeys(protractor.Key.chord(browser.controlKey, "v"));

当我使用这段代码时,我有"未定义"

我在这篇文章中使用此代码在端到端测试中使用跨平台键盘快捷方式,但它不起作用:

browser.controlKey = protractor.Key.CONTROL; //browser.controlKey is     a global variable and can be accessed anywhere in the test specs
browser.getCapabilities().then(function(capabilities){
    if(capabilities.caps_.platform === "MAC")
        browser.controlKey = protractor.Key.COMMAND;
});

elm.sendKeys(protractor.Key.chord(browser.controlKey, "c"));

我想在我的工厂注入我的服务,在我的控制器中使用我的工厂:

调节器

app.home.controller('HomeController', ['$scope', '$http', 'Project', function ($scope, $http, Project) {

    var project = new Project();

    $scope.refresh = function(){
        project.createTable();
    };

    $scope.refresh();

}]);

型号(工厂)

app.project.factory('Project', function (ProjectService) {

    var Project = function (properties) {
        // Model
        this.file    = null;
        this.name      = null;
        this.path  = null;
        this.is_active = null;

        angular.extend(this, properties);
    };

    Project.prototype.setModel = function (obj) {
        angular.extend(this, obj);
    };

    Project.prototype.createTable = function () {
        console.log(this);
        return ProjectService.ok();
    };

    return Project;

});

服务

app.project.service('ProjectService', ['$scope', '$http', function ($scope, $http) {

    this.ok …

如何检查是否使用Protractor,CucumberJS和Chai检查复选框？

var el = 'myCheckbox';

this.expect(element(by.model(el)).to.have.prop("checked", true));

我想将我的 angular 4 迁移到 angular 5。我完成了从 angular 4 到 angular 5 的迁移，现在我的拦截器出现错误以刷新我的令牌。如果出现 401 错误，我将使用此代码拦截所有请求并刷新我的令牌：

import { Observable } from 'rxjs/Observable';
import { Injectable, Injector } from '@angular/core';
import { HttpEvent, HttpInterceptor, HttpHandler, HttpRequest } from '@angular/common/http';
import { UserService } from "./user/services/user.service";
import { SpinnerService } from "angular-spinners";

@Injectable()
export class AngularInterceptor implements HttpInterceptor {
    public userService;
    public spinnerService;

    constructor(private injector: Injector) {
    }

    private applyCredentials = function (req) {
        return req.clone({
            headers: req.headers.set('Authorization', 'Bearer ' + localStorage.getItem('eb-app-token'))
        });
    }; …

我想知道是否可以使用带有淡入淡出效果的 UIScrollView 与 nativescript 请？

例如：https : //medium.com/@luisfmachado/uiscrollview-with-fade-effect-246e332e8b24

我阅读了文档https://nativescript-vue.org/en/docs/elements/components/scroll-view/，但我没有找到这些信息。

我想要这个结果，例如：

你有什么想法吗？谢谢

我不知道如何将本机代码放入我的组件中

<template>
    <ScrollView class="scroll" orientation="vertical" row="1" ref="scrollView">
        <StackLayout marginLeft="10" marginRight="10" class="container-verses">
            <StackLayout horizontalAlignment="center">
                <Label textWrap="true" textAlignment="center" text="hello" color="#FFFFFF" fontSize="20"/>
                ...
                <Label textWrap="true" textAlignment="center" text="hello" color="#FFFFFF" fontSize="20"/>
            </StackLayout>
        </StackLayout>
    </ScrollView>
</template>

<script>
    export default {
        name    : 'FadeScrollView',
        computed: {},
        methods : {
            //
        }
    };
</script>

<style lang='scss' scoped>

</style>

我想知道如何使用 Prisma2 和 Jest 删除表中的所有项目？

我阅读了CRUD 文档并尝试这样做：

用户.test.js

....
import { PrismaClient } from "@prisma/client"

beforeEach(async () => {
    const prisma = new PrismaClient()
    await prisma.user.deleteMany({})
})
...

但我有一个错误：

Invalid `prisma.user.deleteMany()` invocation:
The change you are trying to make would violate the required relation 'PostToUser' between the `Post` and `User` models.

我的数据库

CREATE TABLE User (
  id INTEGER PRIMARY KEY AUTO_INCREMENT NOT NULL,
  name VARCHAR(255),
  email VARCHAR(255) UNIQUE NOT NULL,
  password VARCHAR(255) NOT NULL
);

CREATE TABLE Post …

我想知道在验证错误后如何重新发送带有httpinterceptor的请求？

我检查是否有错误（刷新我的JWT令牌），刷新后我想再次提交失败请求。

httpinterceptor.js：

import { Observable } from 'rxjs';
import { Injectable, Inject, Injector } from '@angular/core';
import { HttpEvent, HttpInterceptor, HttpHandler, HttpRequest, HttpResponse } from '@angular/common/http';
import { UserService } from "./user/services/user.service";
import { Router } from "@angular/router";

@Injectable()
export class AngularInterceptor implements HttpInterceptor {
    public userService;

    constructor(private router: Router,
                private injector: Injector) {
    }

    intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
        const clonedRequest = req.clone();

        this.userService = this.injector.get(UserService);

        return next.handle(req)
            .do(event => {
                if (event instanceof HttpResponse) {
                    //normal …

如何在使用Laravel进行字段模式迁移时定义属性zerofill和size（2）？

Schema::create('books', function (Blueprint $table) {
    $table->integer('reference')->length(2);
});

和这个字段为zerofill。

我想使用播种机：

public function run()
{
    Book::create
    ([
        'reference' => 01
    ]);
}

我想在删除项目*ngFor的*ngFor.

当我删除回复'test2'时,

在我添加了另一个回复之后,'test3'变空了.

<hello name="{{ name }}"></hello>

<form #form="ngForm" (ngSubmit)="submit()" ngNativeValidate class="mt-4">

  <div *ngFor="let content of contents; let indexContent = index; let firstContent = first;">

    <div *ngFor="let message of content.messages; let indexMessage = index; let firstMessage = first;">
      <table>
        <thead>
        <tr>
          <th>Id</th>
          <th>Text</th>
          <th class="text-right">Action</th>
        </tr>
        </thead>
        <tbody>
        <tr *ngFor="let reply of message.replies; let indexReply = index; let firstReply = first;">
          <td [innerHtml]='reply.id'></td>

            <input type="text"
