[javascript] How to get input textfield values when enter key is pressed in react js?

I want to pass textfield values when user press enter key from keyboard. In onChange() event, I am getting the value of the textbox, but How to get this value when enter key is pressed ?

Code:

import TextField from 'material-ui/TextField';

class CartridgeShell extends Component {

   constructor(props) {
      super(props);
      this.state = {value:''}
      this.handleChange = this.handleChange.bind(this);
   }

   handleChange(e) {
      this.setState({ value: e.target.value });
   }

   render(){
      return(
         <TextField 
             hintText="First Name" 
             floatingLabelText="First Name*"
             value={this.state.value} 
             onChange={this.handleChange} 
             fullWidth={true} />
      )
   }
}

Adding onKeyPress will work onChange in Text Field.

<TextField
  onKeyPress={(ev) => {
    console.log(`Pressed keyCode ${ev.key}`);
    if (ev.key === 'Enter') {
      // Do code here
      ev.preventDefault();
    }
  }}
/>

html

<input id="something" onkeyup="key_up(this)" type="text">

script

function key_up(e){
    var enterKey = 13; //Key Code for Enter Key
    if (e.which == enterKey){
        //Do you work here
    }
}

Next time, Please try providing some code.
