Threejs和OrbitControl

Question

我不知道這是否是純JavaScript錯誤。 在下面的類函數中，我添加了一個eventListener，使我返回此錯誤：

Uncaught TypeError: Cannot read property 'call' of undefined

我想澄清的是，所有調用的函數均已正確定義。

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() 返回一個函數，否則它應該是

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

Answer 2

嘗試以下解決方案：

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