import react, {component, proptypes} 'react' import formsy 'formsy-react' export class businessdetailsform extends component {   constructor(props) {     super(props)     this.state = {       state: '',       city: ''     }     this.submitform = this.submitform.bind(this)   }   submitform(data) {      if (this.state.googleinputvalue !== '') {     this.props.dispatch(setsubmitting(true))     dispatch(signupstep2(data))     } else {       this.setstate({ locationerrmsg: 'please select location'})     }   }   render() {     return (       <div>         <formsy.form onsubmit={this.submitform} id="form_validation">           <element name="location">             <field type="text"               name="location"               component={googleautocomplete}               floatinglabeltext="location"               hinttext="location"               id="addresssearchboxfield"               defaultvalue={this.state.location}               onselectplace={this.handleplacechanged}               onchangeinput={this.handleinputchange.bind(this)}             />           </element>           <span style={{color: 'red'}}>{this.state.locationerrmsg}</span>             <span>               <raisedbutton                 type="submit"                 label="next"                 disabletouchripple                 disablefocusripple                                 //ontouchtap={this.handlenext}                                 style={{marginright: '12px', color:"#c5c5c5"}}               />             </span>         </formsy.form>       </div>     )}} 

as in jquery can listen keydown event , prevent default action like

_handleenterkey(event) {     if(event.keycode == 13){           e.preventdefault();           return false;      }  } componentdidmount() {      document.addeventlistener("keydown", this._handleenterkey, false); } componentwillunmount() {      document.removeeventlistener("keydown", this._handleenterkey, false); }
