跟著老師的代碼敲的，也引用到了main中了，為什么大魚出不來，求教了！
var momObj = function() {
this.x;
this.y;
this.bigEye = new Image();
this.bigBody = new Image();
this.bigTail = new Image();
}
momObj.prototype.init = function() {
this.x = canWidth * 0.5;
this.y = canHeight * 0.5;
this.bigEye.src = "/img/bigEye0.png";
this.bigBody.src = "/img/bigSwim0.png";
this.bigTail.src = "/img/bigTail0.png";
}
momObj.prototype.draw = function() {
ctx1.drawImage(this.bigEye, this.x, this.y);
ctx1.drawImage(this.bigBody, this.x, this.y);
ctx1.drawImage(this.bigTail, this.x, this.y);
}
報(bào)錯(cuò)如下：mom.js:18 Uncaught DOMException: Failed to execute 'drawImage' on 'CanvasRenderingContext2D': The HTMLImageElement provided is in the 'broken' state.

this.bigEye.src = "/img/bigEye0.png";
this.bigBody.src = "/img/bigSwim0.png";
this.bigTail.src = "/img/bigTail0.png";
這個(gè)好像有問題，少
加了. 吧
你改成這樣試試看
this.bigEye.src = "./img/bigEye0.png";
this.bigBody.src = "./img/bigSwim0.png";
this.bigTail.src = "./img/bigTail0.png";

同學(xué)您好，對(duì)的，就是您這種寫法就能將下標(biāo)和值同時(shí)取出來了！你可以參考一下“不會(huì)了怎么辦”里面的參考代碼

看到下面的回答是把ctx1改成ctx2就可以了
我試過了
