反应使用危险地使用SetInnerHTML渲染带有html标签的json [英] react use dangerouslySetInnerHTML to render json with html tags

问题描述

我正在尝试使用列表中字符串中的html标签呈现json列表，如下所示 jsbin 。它在Jsbin中工作。但是在我的控制台中，我收到以下警告：

I am trying to render a json list with html tags in the string in a list as follows jsbin. It works in Jsbin. But in my console I got warning below:

warning  Only set one of `children` or `props.dangerouslySetInnerHTML` react/no-danger-with-children

只是想知道是否还有其他方法可以危险地呈现列表SetInnerHTML以避免

just wonder if there is other way to render the list with dangerouslySetInnerHTML to avoid the warning?

const displayList = [
    {
        item: 1,
        text: "<strong>ABC</strong> this should be strong."
    },
    {
        item: 2,
        text: "<a>ABC</a> this should be link."
    },
    {
        item: 3,
        text: "normal text"
    }
];

const App = () => (
    <ul>
        {displayList.map((item, i) => (
            <li key={i}>
                <div dangerouslySetInnerHTML={{
                    __html: item.text
                }}>
                </div>
            </li>
        ))}
    </ul>
);

ReactDOM.render(
    <App />,
    document.getElementById('root')
);

推荐答案

React抱怨使用 dangerouslySetInnerHTML 与安全的反应儿童结合在一起，发生在当您将div标签打开到具有这种特征的< div> open并为儿童准备好了< / div> 。

React is complaining about the use of dangerouslySetInnerHTML in conjunction with safe react children, that happened when you let the div tag opened to such characteristic <div>open and ready for children</div>.

由于使用的是JSX语法扩展，因此这里的解决方案是将整个句子写在一行中：

Since you are using the JSX syntax extension, the solution here is write the whole sentence in a single line:

<div dangerouslySetInnerHTML={{__html: item.text}}></div>

或仅使用单例div标签：

or just using a singleton div tag:

<div dangerouslySetInnerHTML={{
       __html: item.text
     }}/>

通过这种方式，您不会在jsbin上收到错误，因为它是一个反应生产版本，因此该版本并不意味着要告诉您什么可以写得更好。

By the way you are not getting the error on jsbin because it is a react production build, this build is not meant to tell you what could be written better.
