问题描述

我已经为用户创建了登录页面.如果他们点击提交按钮，页面将导航到一个组件(test.component.ts,test.component.html,..).

I have created the login page for the user. If They click the submit button, the page will navigate to one component (test.component.ts,test.component.html,..).

我需要在全屏模式下制作该窗口.像，(html5 中的视频控制全屏).

I need to make that window in full screen mode. like, (video control full screen in html5).

submitLogin() {
  if (this.userName === 'Student' && this.passWord === 'student@123'){
    this.dashboard = true; 
  } else {
    alert('Incorrect Username or Password');
  }
}

我不知道如何实现全屏窗口功能.因为，我是 Angular2 的新手.谁能解决我的问题?.

I don't know how to achieve the full screen window functionality. Because, i am new to Angular2. Can Anyone solve my problem ?.

推荐答案

以下代码仅适用于较新版本的浏览器.从您的问题中，我确实分析过，单击按钮后会调用 submitLogin() .因此，单击按钮后，您可以使用以下方法实现全屏.

The following code will only be feasible for newer versions of browsers. From your question, I do analyze that, submitLogin() is called after clicking the button. So, after clicking the button, you can achieve full screen using the following approach.

   submitLogin() {
     this.toggleFullScreen();
     if(this.userName == "Student" && this.passWord == "student@123"){
      this.dashboard = true; 
     }
     else{
       alert("Incorrect Username or Password");
      }
   }

   toggleFullScreen() {
    let elem =  document.body; 
    let methodToBeInvoked = elem.requestFullscreen || 
     elem.webkitRequestFullScreen || elem['mozRequestFullscreen'] || 
     elem['msRequestFullscreen']; 
    if(methodToBeInvoked) methodToBeInvoked.call(elem);

}

更新:ActiveXObject 仅在 IE 浏览器上可用.所以其他每个用户代理都会抛出错误.您可以使用以下代码:

Updated: ActiveXObject is available only on IE browser. So every other useragent will throw an error. You can use the following code:

 toggleFullScreen() {
        let elem =  document.body; 
        let methodToBeInvoked = elem.requestFullscreen || 
         elem.webkitRequestFullScreen || elem['mozRequestFullscreen'] 
         || 
         elem['msRequestFullscreen']; 
        if(methodToBeInvoked) methodToBeInvoked.call(elem);

    }
