Angular ngx-translate TranslateLoader ohne http Modul

Compatibility with old browsers, as the Firefox version <= 5 to reach, can you do that angular http Do not use module. The NGX-translate Modules bneötigt a loader, It loads the correct language via AJAX request. Also with the XMLHttpRequest and an Observalbe solve this can:

import {Injectable} from '@angular/core';
import {TranslateLoader} from '@ngx-translate/core';
import {Observable} from 'rxjs/Observable';

export class LanguageLoader implements TranslateLoader {

  getTranslation(lang: string): Observable<any> {
    return Observable.create(function (observer) {
    let url = `./assets/i18n/${lang}.json?=` + new Date().getTime();
    let xhr = new XMLHttpRequest();

      xhr.onreadystatechange = function () {
        if (xhr.readyState == XMLHttpRequest.DONE || xhr.readyState == 4) {
              let response = JSON.parse(xhr.responseText);
      }'GET', url, true);

In the app.module.TS can you then embed the loader as follows:

  loader: {provide: TranslateLoader, useClass: LanguageLoader}

        {"id": "Mute"},
        {"id": "Find", "label": "Find..."},
        {"id": "FindAgain", "label": "Find Again"},
        {"id": "Copy"},
        {"id": "CopyAgain", "label": "Copy Again"},
        {"id": "CopySVG", "label": "Copy SVG"},
        {"id": "ViewSVG", "label": "View SVG"},
        {"id": "ViewSource", "label": "View Source"},
        {"id": "SaveAs", "label": "Save As"},
        {"id": "Help"},
        {"id": "About", "label": "About Adobe CVG Viewer..."}

Configure angular German localization

import { LOCALE_ID} from '@angular/core';
import localeDe from '@angular/common/locales/de';
import localeDeExtra from '@angular/common/locales/extra/de';

registerLocaleData(localeDe, localeDeExtra);

Javascript disable all readonly Dropdowns and send via Form

Readonly select-Tags are not allowed in HTML until now, but can be used.

An alternative would be to use the disabled = true attribute, but this will not send the select value on form submission.

An easy solution would be to disable the selection with Javascript and leave it readonly:

$( document ).ready(function() {

The only problem is, that you can still tab throw the form and select elements with your keyboard but the mouse can not select element from the dropdown.

Create animations with JavaScript

Small animation, like that disappear a div block, can setTimeout JavaScript very easy with the function() create.

The logic is always the same:

For each movement frame the size or Posiition of object is changed using the setTimeout function at a certain time, so that at the end of strung together an animation comes out for the human eye.
