Cross Domain iframe elements access in React with (srcDoc):-



 onclickinsideiframe=()=>{
      if(document.getElementById('iframetnd')!==null){

                let iframe = document.getElementById('iframetnd');

                let innerDocument = (iframe.contentDocument)  
                                   ? iframe.contentDocument 
                                   : iframe.contentWindow.document;
                let Obj = innerDocument.getElementsByClassName("navButtons")[0];
                    if(Obj !== undefined){
                        Obj.onclick = ()=>this.func();
          }
       }
    }



  func=()=>{
           this.setState({page:2})
           this.arrangeTest();
        }
