javascript function are not working with angular 5 correctly

Question

I have a problem like this. I am making an angular application. In there, I have made an animated Login. This is my component HTML file.

<div class="panda" xmlns="">
  <div class="ear"></div>
  <div class="face">
    <div class="eye-shade"></div>
    <div class="eye-white">
      <div class="eye-ball"></div>
    </div>
    <div class="eye-shade rgt"></div>
    <div class="eye-white rgt">
      <div class="eye-ball"></div>
    </div>
    <div class="nose"></div>
    <div class="mouth"></div>
  </div>
  <div class="body"> </div>
  <div class="foot">
    <div class="finger"></div>
  </div>
  <div class="foot rgt">
    <div class="finger"></div>
  </div>
</div>
<form>
  <div class="hand"></div>
  <div class="hand rgt"></div>
  <h1>Panda Login</h1>
  <div class="form-group">
    <input required="required" class="form-control"/>
    <label class="form-label">Username    </label>
  </div>
  <div class="form-group">
    <input id="password" type="password" required="required" class="form-control"/>
    <label class="form-label">Password</label>
    <p class="alert">Invalid Credentials..!!</p>
    <button class="btn">Login </button>
  </div>
</form>
<script>
  $('#password').focusin(function(){
    $('form').addClass('up')
  });
  $('#password').focusout(function(){
    $('form').removeClass('up')
  });

  // Panda Eye move
  $(document).on( "mousemove", function( event ) {
    var dw = $(document).width() / 15;
    var dh = $(document).height() / 15;
    var x = event.pageX/ dw;
    var y = event.pageY/ dh;
    $('.eye-ball').css({
      width : x,
      height : y
    });
  });

  // validation


  $('.btn').click(function(){
    $('form').addClass('wrong-entry');
    setTimeout(function(){
      $('form').removeClass('wrong-entry');
    },3000 );
  });

</script>

This is my component CSS file.

This is my module.ts file.

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import {ROUTING} from './app.routing';


import { AppComponent } from './app.component';
import { HomeComponent } from './home/home.component';
import { NavbarComponent } from './navbar/navbar.component';
import { SetColorDirective } from './directives/set-color.directive';
import { AdminLoginComponent } from './admin/admin-login/admin-login.component';


@NgModule({
  declarations: [
    AppComponent,
    HomeComponent,
    NavbarComponent,
    SetColorDirective,
    AdminLoginComponent
  ],
  imports: [
    BrowserModule,
    ROUTING
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

And Here I am providing my angular-cli.json file.

    },

      "exclude": "**/node_modules/**"
    }
  ],
  "test": {

    }
  },
  "defaults": {

  }
}

My view file is giving the right output when I hit ng serve. But animation is not working without giving any error. I have tried so many examples and the given suggestion even in the stack overflow examples. But those examples were unable to full fill my requirements. Can someone help me to solve this problem?

Thank You!!

You shouldn't be mixing jQuery and messing around with the DOM like this and Angular. The problem itself might be that view encapsulation mangles the class names and thus the embedded Javascript in the template no longer works correctly. — Ingo Bürk, Jun 17 '18 at 07:59

First: They are not javascript functions. You have used jQuery functions.

Second: Scripts are not allowed in component's HTML. You can use script tags only in index.html. See this. You can try this instead.
