reactjs - In react JS fields losing focus after first onChange -


i using redux-form when start typing focus goes out first time in react.

in component below, input field loses focus after typing character. while using chrome's inspector, looks whole form being re-rendered instead of value attribute of input field when typing.

please see below code:

<field         name='description'        // onchange={this.handlechange.bind(this)}         //value={this.state.description}         component={props => {           return (             <mentiontextarea  {...props} usertags={usertags} tags={posttags}/>            )         }}

mentiontextarea component:

import react, {component, proptypes} 'react' import { mentionsinput, mention } 'react-mentions' import defaultstyle './defaultstyle'  class mentiontextarea extends component {     constructor(props) {         super(prop)     }     handleonchange (e) {         this.props.input.onchange(e.target.value);      }     render() {        // const { input, meta, ...rest } = this.props;         return (             <mentionsinput                  value={this.props.input.value || ''}                 onchange={this.handleonchange.bind(this)}                 singleline={false}                 style={ defaultstyle }                 markup="@[__display__](__type__:__id__)"                 >                    <mention trigger="@"                         data={this.props.usertags}                         type="usertags"                         style={{ backgroundcolor: '#d1c4e9' }}                         rendersuggestion={ (suggestion, search, highlighteddisplay) => (                             <div classname="user">                                 { highlighteddisplay }                             </div>                         )}                     />                     <mention trigger="#"                         data={this.props.tags}                         type="tags"                         style={{ backgroundcolor: '#d1c4e9' }}                         rendersuggestion={ (suggestion, search, highlighteddisplay) => (                             <div classname="user">                                 { highlighteddisplay }                             </div>                         )}                     />             </mentionsinput>         );     } }  export default mentiontextarea

please help!

thanks in advance,

it's common problem people new redux-form please check issue you'll find answer there.

you must define stateless function outside of render() method, or else recreated on every render , force field rerender because component prop different. example official redux-form documentation:

// outside render() method const renderfield = (field) => (     <div classname="input-row">       <input {...field.input} type="text"/>       {field.meta.touched && field.meta.error &&         <span classname="error">{field.meta.error}</span>}     </div>   )  // inside render() method <field name="myfield" component={renderfield}/>
