javascript - TypeError: Cannont Read Property `State` of Undefined

Getting the error :

TypeError: Cannot read property 'state' of undefined

I face this error when i am going to get my input state value by event onSubmit() .

onFormSubmit(event){
    event.preventDefault();
    console.log(this.state.term);
}

Answer

Use arrow function instead so:

Change

onFormSubmit(event){
    event.preventDefault();
    console.log(this.state.term);
}

To

onFormSubmit= (event)=>{

    event.preventDefault();
    console.log(this.state.term);
}
