问题描述
I am trying to write a React component for HTML heading tags(h1, h2, h3, etc.), where the heading level is specified via a prop.
I tried to do this like this:
<h{this.props.level}>Hello</h{this.props.level}>
and expected output like:
<h1>Hello</h1>
but this is not working. Is there any possible method to do this?
解决方案
No way to do that in-place, just put it in a variable (with first letter capitalised):
const CustomTag = `h${this.props.level}`;
<CustomTag>Hello</CustomTag>
