1.Skulpt我的项目里的lib文件夹下新建js文件

const $builtinmodule = function () {    // 获取画布容器    const selector = Sk.TurtleGraphics?.target || 'turtle';    const target = typeof selector === 'string' ? document.getElementById(selector) : selector;    // 革除画布    function clearCanvas() {        while (target.firstChild) {            target.removeChild(target.firstChild);        }    }    // 插入图片,标签款式优先级高于less    const appendImg = (target, url, styleAttrs) => {        const img = new Image();        img.src = url;        if (styleAttrs) {            img.style.width = styleAttrs.width;            img.style.height = styleAttrs.height;        }        target.appendChild(img);    };    // 生成二维码    function createdQRCode(value) {        Sk.dependencies.qrcode.toDataURL(value, {            width: 200,            height: 200        }).then(url => {            appendImg(target, url);        });    }    const newModule = {};    const robotFunc = function ($gbl, $loc) {        // robot实例化时执行的办法,能够了解为constructor里的办法        appendImg(target, Sk.dependencies.tutu, {width: '200px', height: '200px'});                // 能够了解为实例上挂的办法,能够挂很多        $loc.makeqr = new Sk.builtin.func((self, value) => {            // 革除画布            clearCanvas();            // 生成二维码            createdQRCode(value.v);        });    };    // 能够了解为 new Class();    newModule.robot = Sk.misceval.buildClass(newModule, robotFunc, 'robot', []);    return newModule;};export default $builtinmodule;
