如何在 Next JS Applcation 中將字符串轉換為 HTML 元素？

Question

我已將產品描述作為 HTML 元素保存到這樣的數據庫中。 但是當我將這些數據渲染到 div 中時，它顯示為字符串。 我想在我的Next JS 應用程序中顯示所有數據，例如 HTML 元素。 我試過 JSON.parse，但它不起作用。

如果有人可以幫助我解決這個問題，我們將不勝感激。

下一個 Js 應用代碼

const Product = ({product}) => {
    return (

                                            alt={product.images[0].alternativeText}
                                        />
                                    </div>
                                </div>
                            </div>
                            <div className="col-xl-7 col-lg-7 info-box">
                                <div className="product-info">

                                        <hr/>

                                        <h5>Price: <span>{product.price + "$"}</span></h5>

                                    <div className="product-des">
                                        {product.description}
                                    </div>
                                </div>
                            </div>
                        </div>
                    </div>
                </div>
            </Layout>
        </Fragment>
    );
}

Answer 1

因為你想顯示原始 HTML，所以這個

<div className="product-des">
  {product.description}
</div>

應該改為

<div className="product-des" dangerouslySetInnerHTML={{ __html: product.description }}>

這在官方文檔中有介紹

dangerouslySetInnerHTML是 React 在瀏覽器 DOM 中使用innerHTML的替代品 [...] 你必須輸入dangerouslySetInnerHTML並使用__html鍵傳遞 object

在這種情況下，您還必須注意設置原始 HTML 的風險

通常，從代碼中設置 HTML 是有風險的，因為很容易無意中將您的用戶暴露給跨站點腳本 (XSS) 攻擊
