Get global element state in react js

Step 1 :- Get global Element static

var getElement = document.getElementsByID(‘IdName’); 

Step 2 :- Create function to get element __reactInternalInstance state

getReactElement(dom) {for (var key in dom) {
    if (key.startsWith(“__reactInternalInstance$”)) {
       var compInternals = dom[key]._currentElement;
       var compWrapper = compInternals._owner;
       var comp = compWrapper._instance;
       return comp;
    }
 }
 return null;
}

Step 3 :- Get state here

var getProps = getReactElement(getElement);

Step 4 :- Set new state here

getProps.setState({
   stateName : stateValue 
})
