我无法通过加载中的每种语言来查看详细信息

Question

有人可以帮我吗？我想通过跟随父类的每种语言（英语，法语，高棉语）来呈现细节。我在构造函数中将变量初始化为英语。我尝试按照每种语言显示现有文档，但它仍然没有看到我的代码！

初始化变量

 this.events.subscribe('renderViewLang-' + this.documentId, (lang: any) => {
      this.currentViewlanguage = lang;
      setTimeout(() => {
       this.buildContentAsHTML();
      }, 1000);
    });

显示首次加载

    public ionViewDidLoad() {
    console.log('ionViewDidLoad DetailTabContentPage[' + this.documentId + ']');
    this.alertService.showLoading();
    this.docSRV.getDocument(this.documentId, 1)
      .subscribe((data: any) => {
        this.docContentDTO = data; 
        setTimeout(() => {
        if(this.currentViewlanguage === 'en'){
            if(this.docContentDTO !== null) {
              this.currentViewlanguage = 'en';
              this.buildContentAsHTML();
           } 
        } else if (this.currentViewlanguage === 'fr') {
            if(this.docContentDTO !== null) {
              this.currentViewlanguage = 'fr';
              this.buildContentAsHTML();
            }
        } else if (this.currentViewlanguage === 'kh') {
            if(this.docContentDTO !=  null) {
              this.currentViewlanguage = 'kh';
              this.buildContentAsHTML();
            }
        } 
        }, 1000);
      },
      error => {
        this.alertService.showError(error);
      },
      () => { // complete
        this.alertService.dismissLoading();
      });
  }
