javascript - javascript 函数无法正确使用 angular 5

问题描述

我有这样的问题。我正在制作一个角度应用程序。在那里，我做了一个动画登录。这是我的组件 HTML 文件。

<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>

这是我的 module.ts 文件。

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 { }

在这里，我提供了我的 angular-cli.json 文件。

{
  "$schema": "./node_modules/@angular/cli/lib/config/schema.json",
  "project": {
    "name": "frontend"
  },
  "apps": [
    {
      "root": "src",
      "outDir": "dist",
      "assets": [
        "assets",
        "favicon.ico"
      ],
      "index": "index.html",
      "main": "main.ts",
      "polyfills": "polyfills.ts",
      "test": "test.ts",
      "tsconfig": "tsconfig.app.json",
      "testTsconfig": "tsconfig.spec.json",
      "prefix": "app",
      "styles": [
        "../node_modules/bootstrap/dist/css/bootstrap.min.css",
        "styles.css"

      ],
      "scripts": [

        "../node_modules/jquery/dist/jquery.min.js",
        "../node_modules/bootstrap/dist/js/bootstrap.js"
      ],
      "environmentSource": "environments/environment.ts",
      "environments": {
        "dev": "environments/environment.ts",
        "prod": "environments/environment.prod.ts"
      }
    }
  ],
  "e2e": {
    "protractor": {
      "config": "./protractor.conf.js"
    }
  },
  "lint": [
    {
      "project": "src/tsconfig.app.json",
      "exclude": "**/node_modules/**"
    },
    {
      "project": "src/tsconfig.spec.json",
      "exclude": "**/node_modules/**"
    },
    {
      "project": "e2e/tsconfig.e2e.json",
      "exclude": "**/node_modules/**"
    }
  ],
  "test": {
    "karma": {
      "config": "./karma.conf.js"
    }
  },
  "defaults": {
    "styleExt": "css",
    "component": {}
  }
}

当我点击 ng serve 时，我的视图文件给出了正确的输出。但是动画在没有任何错误的情况下无法正常工作。即使在堆栈溢出示例中，我也尝试了很多示例和给出的建议。但是这些示例无法完全满足我的要求。有人可以帮我解决这个问题吗？

谢谢你！！

解决方案

首先：它们不是javascript函数。你已经使用了 jQuery 函数。

第二：组件的 HTML 中不允许使用脚本。您只能在 index.html 中使用脚本标签。看到这个。你可以试试这个。
