解析React中字符串内的嵌套HTML？

Question

I'm building a type ahead feature in React.

I have wrapper component that has an array of objects, and it renders item ; which's a stateless component.

So, suppose I have const name= 'Hasan' . Which gets parsed to >> const parsedName = Ha<span>san</span> ; assuming the term to search for is san .

I have tried dangerouslySetInnerHTML={{ __html: parsedName }} attribute on the parent element, but it didn't work.

With plain html this would be: el.innerHTML = parsedName

The goal is to style the span as desired. Any ideas?

Answer 1

 class Test extends React.Component { render() { const name = 'san'; const parsedName = name.replace(new RegExp('san', 'ig'), '<span>span</span>'); return ( <div dangerouslySetInnerHTML={{__html: parsedName}}/> ); } } ReactDOM.render( <Test/>, document.getElementById('container') );

Without code its hard to tell what's wrong. I have created a working snippet here that might help you debug your issue.

Updated the example based on the comment.
