javascript - React his.setState is not a function -


this parent element :

  changeddata(){     this.setstate({       changed: true     }).bind(this)   }

i'm passing child: 

<aboutme  changeddata={this.changeddata} auth={this.props.auth} profile={profile}/>

the child:

  datachanged(data) {             this.props.changeddata();           console.log("datachanged!!")    }

make sure bind this before calling within function. can either change changeddata function signature es6 arrow function auto bind it:

changeddata = () => { }

or can bind in child component this:

<aboutme      changeddata={this.changeddata.bind(this)}      auth={this.props.auth}      profile={profile}/>
