I don't understand if it is a pure javascript mistake or not. In the class function below I added an eventListener that return me this error:
Uncaught TypeError: Cannot read property 'call' of undefined
I want to clarify that all the function called are correctly defined.
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);
}
除非that.view.show()
返回一个函数,否则它应该是
this.controls.addEventListener( 'change', that.view.show );
尝试以下解决方案:
this.controls.addEventListener( 'change', function(){ that.view.show()});
