_this3.state.method is not a function










0















I have a .js file as such:



My Class Component:



[...]
constructor(props, context)
[...]
this.method1 = this.method1.bind(this);


anotherMethod()
[...]
this.state.method1();


method1()
//Do something



I am getting this error: _this3.state.method1 is not a function. I tried following some other known solutions in here.



I have a few questions:



  1. What is the root cause?

  2. What is _this3 an where did it come from?

Thanks.



EDIT: I found the solution which is to remove the "state". Instead of this.state.method1(), it should be this.method1(). Just curious how come i do not need the "state" when i bind it above?

  • It seems you are not aware of what state is in React context. I recommend you to read more about development pattern in React.

Because method1 not in state, This is component self function, Unless method1 in state like the following.



this.state = method1:() => /*Do something*/ 


You can read React website about state and Handling Events.
