how to create form using react js?

<form>
  <label>
    Name:
    <input type="text" name="name"开发者_如何学JAVA />
  </label>
  <input type="submit" value="Submit" />
</form>

such as <input>, <textarea>, and <select> typically maintain their own state and update it based on user input. In React, mutable state is typically kept in the state property of components, and only updated with setState().

If I got your point.
The thing you need is Uncontrolled Components.
Take a look at this document: Uncontrolled Components

you can still use document.getElementById if it helps in your case
