React setstate method's callback is not fired












0














I have a strange question about set state's callback function in React. Everything is working fine in React 15 but once I upgraded the react version to 16, the set state's callback function is not getting fired. I have tried almost everything but I could not clearly find out what makes this issue.



I have tried binding the function in the constructor, using an anonymous function inside the set state method but none of them actually worked.



Then I tried downgrading the react version back to 15 and ran the project and I was able to fire the callback method (tested by putting an alert box inside the callback function).



Here's the exact code that i'm using in my sample project:



This function is called on a button click



incrementCounter() {
this.setState({
currentCount: this.state.currentCount + 1
}, this.callbackfuncsajad.bind(this));
}


This is the set state's callback function



callbackfuncsajad = () => {
alert('in the callback');
}


This is my package.json to check if there's any version mismatch:




  • "react": "^15.6.2"

  • "react-dom": "^16.6.3"

  • "@types/react": "^15.0.35"

  • "@types/react-dom": "^15.5.8"

  • "typescript": "2.4.1"


As a side note:
I am using Visual Studio 2017 ASP.NET's default React.JS template for my project. The project comes by default with React 15 along with typescript.



Would be a big time help if anyone could figure this issue out.



Thanks.

  • Please, provide stackoverflow.com/help/mcve . It's unknown how incrementCounter is used. this could be already wrong there.

  • There is a mismatch between the react and react-dom's version. Please keep the version of both react and react-dom same. If you want to use the latest version of react then keep "react": "16.6.3" and "react-dom": "16.6.3"

    @klvenky The callback is an arrow function so no need to bind.

Hi I think its due to parent context, so try somthing like this.



incrementCounter() {
this.setState({
currentCount: this.state.currentCount + 1
}, () => { this.callbackfuncsajad() });


}



Hope it helps.
If you still face this problem kindly share code for proper deduction.
