我有以下情节代码:

            var element = document.getElementById(scope.changeid);

        function getData(division,redraw) {
            var employeeData = [];
            if (!division) {
                $http.get(api.getUrl('competenceUserAverageByMyDivisions', null)).success(function (response) {
                    processData(response,redraw);
                });
            }
            else {
                $http.get(api.getUrl('competenceUserAverageByDivision', division)).success(function (response) {
                    processData(response,redraw);
                })
            }

        }

        function processData(data,redraw) {
            var y = [],
                x1 = [],
                x2 = [];

            data.forEach(function (item) {
                y.push(item.user.profile.firstname);
                x1.push(item.current_level);
                x2.push(item.expected);
            });

            var charData = [{
                    x: y,
                    y: x1,
                    type: 'bar',

                    name: $filter('translate')('COMPETENCES.GRAPH.CURRENT'),
                    marker: {
                        color: '#23b7e5'
                    }
                }, {
                    x:y,
                    y:x2,
                    type: 'bar',
                    marker: {
                        color: '#f05050'
                    }, …

我有以下composer.json文件:

    {
    "name": "laravel/laravel",
    "description": "The Laravel Framework.",
    "keywords": ["framework", "laravel"],
    "license": "MIT",
    "type": "project",
    "require": {
        "php": ">=5.6.4",
        "intervention/image": "dev-master",
        "laravel/framework": "5.4.*",
        "laravel/tinker": "~1.0",
        "predis/predis": "^1.1",
        "quickpay/quickpay-php-client": "1.0.*",
        "sendgrid/sendgrid": "~6.0"
    },
    "require-dev": {
        "fzaninotto/faker": "~1.4",
        "mockery/mockery": "0.9.*",
        "phpunit/phpunit": "~5.7"
    },
    "autoload": {
        "classmap": [
            "database"
        ],
        "psr-4": {
            "App\\": "app/"
        }
    },
    "autoload-dev": {
        "psr-4": {
            "Tests\\": "tests/"
        }
    },
    "scripts": {
        "post-root-package-install": [
            "php -r \"file_exists('.env') || copy('.env.example', '.env');\""
        ],
        "post-create-project-cmd": [
            "php artisan key:generate"
        ],
        "post-install-cmd": [ …

所以我有以下组件:

export class ModuleComponentComponent implements OnInit {
    dropzoneConf;
    fileService = environment.getFileUrl;

    constructor(
        private moduleComponentService: ModuleComponentService) {
    }

    @Input()
    selectedComponent: ModuleComponent;

    ngOnInit() {
        this.setDropZoneConfig();
    }    
}

在那我有以下的HTML:

<h3 class="m-portlet__head-text m--font-success">
   <input class="form-control" type="text" [ngModel]="selectedComponent.title" />
</h3>

以及我在html中添加组件的方式:

<div class="col-lg-8 col-x1-12" *ngIf="selectedComponent != null">
   <app-module-component [selectedComponent]="selectedComponent"></app-module-component>
</div>

当我在输入字段中输入内容时,它不会更新selectedComponent.title变量

谁能告诉我发生了什么事？

我有以下代码：

import {Component} from '@angular/core';
import {DocumentScanner, DocumentScannerOptions, DocumentScannerSourceType} from '@ionic-native/document-scanner';

@Component({
    selector: 'app-tab2',
    templateUrl: 'tab2.page.html',
    styleUrls: ['tab2.page.scss']
})
export class Tab2Page {

    constructor(private documentScanner: DocumentScanner) {
    }

    scan() {
        const opts: DocumentScannerOptions = {
            sourceType: DocumentScannerSourceType.CAMERA,
            fileName: 'ticketScan.png',
            quality: 100,
            returnBase64: true
        };
        this.documentScanner.scanDoc(opts)
            .then((res: string) => console.log(res))
            .catch((error: any) => console.error(error));
    }
}

当我运行它时，我收到以下错误：

11:42 'DocumentScanner' refers to a value, but is being used as a type here.

谁能告诉我为什么会这样？

如果没有www并且字符串被命名或https://example.com,如何将www添加到网址？

例:

http://ellos.dk //should be http://www.ellos.dk

我知道这可能是相当基本但我似乎找不到一个漂亮的解决方案
