重现代码 | Code example:

       const BODY = document.getElementsByTagName('body')[0];
        function setElementStyle(dom, object) {
            if (object == null) return;

                    dom.style[key] = object[key];
                }
            }
        }

        function createElementWithStyle(tag, style, child) {
            const el = document.createElement(tag);
            setElementStyle(el, style);
            if (Array.isArray(child)) {
                child.forEach(c => el.appendChild(c));
            } else if (child) {
                el.appendChild(child);
            }
            return el;

            return document.createTextNode(content);

        );
        BODY.appendChild(div);
        div.scrollLeft = 1000;
        console.log(target.offsetLeft);
