在React.js中将字符串转换为真正的HTML

如果字符串中包含html,则可以使用 dangerouslySetInnerHTML 将其呈现为html。

return (
  <div>
    {models.map(model => (
      <a href="/sofa">
        <div className="Parcelas" key={model.id}>
          <img
            src={"url" + model.image}
            className="ParcImage"
            alt="sofa"
          />
          <h1>Sofá {model.name}</h1>
          <h2>
            1,200<span>€</span>
          </h2>

          <p
            className="Features"
            dangerouslySetInnerHTML={{ __html: model.description }}
          />

          <button className="Botao">
            <p className="MostraDepois">Ver Detalhes</p>
            <span>+</span>
          </button>
          <img src="../../img/points.svg" className="Decoration" alt="points" />
        </div>
      </a>
    ))}
  </div>
);

检查尝试附加到节点的文本是否没有像这样转义:

model: {
  description: '<h1>Hi there!</h1>'
}

而不是这个:

model: {
  description: '<h1>Hi there!</h1>'
}

如果是转义的,则应将其从服务器端转换。

如果你不能尝试这样的事情:

<p className="Features">{model.description.fromCharCode(183)}</p>

另一个选项是ReactHtmlParser和unescapingtml的组合:

import ReactHtmlParser from "react-html-parser";

let model = [
  {
    description: "<h1>Hello There</h1>"
  },
  {
    description: "&lt;h1&gt;Hello There&lt;/h1&gt;"
  }
];

function App() {
  function unescapeHTML(html) {
    var escapeEl = document.createElement("textarea");
    escapeEl.innerHTML = html;
    return escapeEl.textContent;
  }

  return (
    <div className="App">
      {model.map(des => {
        return ReactHtmlParser(unescapeHTML(des.description));
      })}
    </div>
  );
}
