Question

我是使用three.js文件的初学者，现在想要使用three.js加载vrmloader对象

以下是代码

<html lang="en">

                color: #fff;`enter code here`
                margin: 0px;
                overflow: hidden;
            }
            #info {
                color: #fff;
                position: absolute;
                top: 10px;
                width: 100%;

                z-index: 100;
                display:block;
            }
            #info a, .button { color: #f00; font-weight: bold; text-decoration: underline; cursor: pointer }

        if (!Detector.webgl) Detector.addGetWebGLMessage();

        var container, stats;

        var camera, controls, scene, renderer;

        var cross;

        init();
        animate();

        function init() {

            camera = new THREE.PerspectiveCamera(60, window.innerWidth / window.innerHeight, 0.01, 1e10);
            camera.position.z = 6;

            controls = new THREE.TrackballControls(camera);

            controls.rotateSpeed = 5.0;
            controls.zoomSpeed = 5;
            controls.panSpeed = 2;

            controls.noZoom = false;
            controls.noPan = false;

            controls.staticMoving = true;
            controls.dynamicDampingFactor = 0.3;

            scene = new THREE.Scene();

            scene.add(camera);

            // light

            var dirLight = new THREE.DirectionalLight(0xffffff);
            dirLight.position.set(200, 200, 1000).normalize();

            camera.add(dirLight);
            camera.add(dirLight.target);

            var loader = new THREE.VRMLLoader();
            loader.addEventListener('load', function (event) {

                scene.add(event.content);

            });
            loader.load(' JScript/house.wrl');

            // renderer

            renderer = new THREE.WebGLRenderer({ antialias: false });
            renderer.setSize(window.innerWidth, window.innerHeight);

            container = document.createElement('div');
            document.body.appendChild(container);
            container.appendChild(renderer.domElement);

            stats = new Stats();
            stats.domElement.style.position = 'absolute';
            stats.domElement.style.top = '0px';
            container.appendChild(stats.domElement);

            //

            window.addEventListener('resize', onWindowResize, false);

        }

        function onWindowResize() {

            camera.aspect = window.innerWidth / window.innerHeight;
            camera.updateProjectionMatrix();

            renderer.setSize(window.innerWidth, window.innerHeight);

            controls.handleResize();

        }

        function animate() {

            requestAnimationFrame(animate);

            controls.update();
            renderer.render(scene, camera);

            stats.update();

        }

    </script>

</body>

当我尝试运行这些示例时，它会在第125行的VRMLLoader.js文件中显示错误，例如“Uncaught TypeError：无法读取未定义的属性'长度”

谢谢， PRATIK

对象长度未在three.js中定义
