React check if form is dirty

React check if form is dirty

Create a startpoint and put that in your state.

const startState = {
    a: true,
    b: false
}

Change your state
this.state = this.startState;
Compare it to startState
this.state = this.startState;

Full Code:
const startState = 
{ 
a: true, 
b: false 
} 
this.state = this.startState; 
addAction()
{ 
 if( JSON.stringify(startState) !== JSON.stringify(this.state)
  { /* Some code goes here */}
 }


Thank you
