如何限制html标签属性验证？

Question

您好，已创建如下 html 元素：

var element = document.createElement('div');
element.innerHTML = `<img src="fail" onerror="alert();" />`;
element.setAttribute('id', 'check');
document.body.append(element);

// removed element from DOM
 element.parentNode.removeChild(element);

当您运行此代码时，您将看到如下控制台错误：

是否有任何解决此控制台错误的建议？

我尝试了下面的 lke 并解决了我的 pblm

 private static removeElement(): void {
         // Removes an element's attibute to avoid html tag validation
         let nodes: HTMLCollection = this.wrapElement.children;
         for (let j: number = 0; j < nodes.length; j++) {
             let attribute: NamedNodeMap = nodes[j].attributes;
             for (let i: number = 0; i < attribute.length; i++) {
                 this.wrapElement.children[j].removeAttribute(attribute[i].localName);
             }
         }
    }
