如何切换2个画布

Question

我想浏览画布页面，我尝试使用此代码，但它们给了我一个错误;

        if (e.keycode == 13) {
            theCanvas.style.visibility == 'visible'
            theCanvas.style.visibility = 'hidden';
            theCanvas1.style.visibility = 'visible';
        } else {
            theCanvas.style.visibility = 'visible';
            theCanvas1.style.visibility = 'hidden';
        }
    });

Answer 1

试试这个

        if (e.keycode == 13) {
            theCanvas.style.visibility = 'hidden';
            theCanvas1.style.visibility = 'visible';
    });

不需要else，只需要主要的if语句
