react use dangerouslySetInnerHTML to render json with html tags

问题

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

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')
);

回答1:

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>.

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>

or just using a singleton div tag:

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

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.

回答2:

Remove the enclosing tag of your div element in your component so that it looks like the following code:

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

According to this, it should remove the warning.

回答3:

Add inline comment on top of dangerouslySetInnerHTML and inside div element if you use ESLint

<div
   // eslint-disable-next-line react/no-danger
   dangerouslySetInnerHTML={{ __html: html }}
/>
