Question

我目前正在使用角度2和打字稿来玩离子2。现在我正在尝试在html页面中编写一些脚本（或将其包含在文件中）。

我知道，javascript库应该包含在index.html文件中，该文件位于www根文件夹中。但是如果我想在单个html页面中插入脚本呢？

例如，我需要在页面上有一个浮动立方体。我通过在root html文件中包含three.js（3D库）来做正确的事，但是在页面html文件中包含一个floatingcube.js文件（或者在文件中编写脚本），这是行不通的。

我不知道我是否在这里犯了错误，但也许有人知道如何使用外部库以及如何在离子2中编写脚本。

编辑：以下是旋转立方体JS部分：

JS：

var camera;
var scene;
var renderer;
var mesh;
var geometry;
var material1;
var material2;
var material3;
var material4;
var material5;
var material6;
var materials;
var meshFaceMaterial;
var isMouseDown = false;



init();
animate();

function init() {

    window.addEventListener('mousedown', onMouseDown);
    window.addEventListener('mouseup', onMouseUp);
    window.addEventListener("touchstart", handleStart);
    window.addEventListener("touchend", handleEnd);

    camera = new THREE.PerspectiveCamera( 60, window.innerWidth / window.innerHeight, 1, 1000 );
    camera.position.z = 25;

    scene = new THREE.Scene();

  light = new THREE.AmbientLight( 0xE6E6E6 );
  scene.add( light );

    geometry = new THREE.CubeGeometry( 10, 10, 10);
    material1 = new THREE.MeshPhongMaterial( { map: THREE.ImageUtils.loadTexture('img/cub1.jpg') } );
    material2 = new THREE.MeshPhongMaterial( { map: THREE.ImageUtils.loadTexture('img/cub2.jpg') } );
    material3 = new THREE.MeshPhongMaterial( { map: THREE.ImageUtils.loadTexture('img/cub3.jpg') } );
    material4 = new THREE.MeshPhongMaterial( { map: THREE.ImageUtils.loadTexture('img/cub4.jpg') } );
    material5 = new THREE.MeshPhongMaterial( { map: THREE.ImageUtils.loadTexture('img/cub5.jpg') } );
    material6 = new THREE.MeshPhongMaterial( { map: THREE.ImageUtils.loadTexture('img/cub6.jpg') } );

    materials = [material1, material3, material5, material6, material4, material2];

    meshFaceMaterial = new THREE.MeshFaceMaterial( materials );

    mesh = new THREE.Mesh(geometry, meshFaceMaterial );
    mesh.position.z = 0;
    scene.add( mesh );

    renderer = new THREE.WebGLRenderer();
    renderer.setSize( window.innerWidth, window.innerHeight );
document.getElementById('render').appendChild( renderer.domElement );   
    window.addEventListener( 'resize', onWindowResize, false );

    render();
}

function onMouseDown(){
    isMouseDown = true;
}

function onMouseUp(){
    isMouseDown = false;
}

function handleStart(){
    isMouseDown = true;
}

function handleEnd(){
    isMouseDown = false;
}

function animate() {
 if(!isMouseDown){
        mesh.rotation.x += .012;
        mesh.rotation.y += .014;
        mesh.rotation.z += .018;
    }
 else {
        mesh.rotation.x += .0;
        mesh.rotation.y += .0;
        mesh.rotation.y += .0;
 }
    render();
    requestAnimationFrame( animate );
}

function render() {
    renderer.render( scene, camera );
}

function onWindowResize() {
    camera.aspect = window.innerWidth / window.innerHeight;
    camera.updateProjectionMatrix();
    renderer.setSize( window.innerWidth, window.innerHeight );
    render();
}
