Threejs和轨道控制

Question

我不明白这是不是纯粹的javascript错误。在下面的类函数中，我添加了一个eventListener，它返回给我这个错误：

Uncaught TypeError: Cannot read property 'call' of undefined

我想澄清所有被调用的函数都已正确定义。

function OrbitController(v){
var that = this;
this.view = v;
this.controls = new THREE.OrbitControls(this.view.getCamera(),this.view.renderer.domElement);
this.controls.addEventListener( 'change', that.view.show());// Uncaught TypeError: Cannot read property 'call' of undefined
this.controls.target = new THREE.Vector3(0, 0, 0);
}

Answer 1

除非that.view.show() 返回一个函数，否则它应该只是

this.controls.addEventListener( 'change', that.view.show ); 

Answer 2

尝试使用此解决方案：

this.controls.addEventListener( 'change',  function(){ that.view.show()});
