i18n多向RTL角

标签: angular multilingual angular-i18n

我正在使用角度4,并且尝试将i18n技术应用到我的应用中, 问题是:我不知道将LTR / RTL方向写在翻译message.ar.xlf文件中的哪个位置, 即使我在使用 i18n-dir dir =“ ltr” 的原始html文件中的每个标记中都提到了它,我也无法从cmd ng提取的message.xlf文件中获得方向xi18n ,所以我无法更改页面的方向:/

New-post.component.html

<div class="row">
    <div class="col-sm-8 col-sm-offset-2">
      <h2 i18n="@@newPost" i18n-dir dir="ltr">New Post</h2>
      <form [formGroup]="postForm" (ngSubmit)="onSavePost()">
        <div class="form-group">
          <label for="title" i18n="title" i18n-dir dir="ltr">Title</label>
          <input type="text" id="title"
                 class="form-control" formControlName="title">
        </div>
        <div class="form-group">
          <label for="content" i18n="content" i18n-dir dir="ltr">Content</label>
          <textarea id="content"
                    class="form-control" formControlName="content">
          </textarea>
        </div>
        <button class="btn btn-primary" [disabled]="postForm.invalid "
            type="submit" i18n="save"  dir="ltr">Save</button>
      </form>
    </div>
  </div>

糟糕: 我终于找到了答案,这很容易;) app.component.html dir中有一个html属性,该属性允许值“ rtl”或“ ltr”并相应地对齐其内容。

app.component.html

<app-header></app-header>
<div class="container" dir="{{textDir}}">
    <router-outlet></router-outlet>
</div>

然后通过监听app.component.ts中的TranslateService中的onLangChange事件,并检查其中的默认Lang是否为阿拉伯语,然后将属性设置为“ rtl”:

app.component.ts

import { Component } from '@angular/core';
import { TranslateService, LangChangeEvent } from '@ngx-translate/core';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {

  textDir: string = 'ltr';

  constructor(private translate: TranslateService) {

//this is to determine the text direction depending on the selected language

    this.translate.onLangChange.subscribe((event: LangChangeEvent) =>
    {
      if(event.lang == 'ar')
      {
        this.textDir = 'rtl';
      } 
      else
      {
        this.textDir = 'ltr';
      }
    });
  }

  

}

这对我来说很有效;
