components

Problem: Currently, I have a LoginForm component that has an "on-success" handler function handleOnSuccess . This the then linked to the parent component with an onTokenUpdate property defined by a "token-update" handler function handleUpdateToken . The problem is that the setState in the handleUpdateToken function is forcing an undesired rerender. Desired Outcome: What I ultimately need is to update the LoginForm component property token with the value obtained on success WITHOUT performing a rerender. Is this even possible? According to React: Update Child Component Without Rerendering

How do i load my React toolbar component conditionally on state change? constructor(props) { super(props); this.state = { currentpagenum: 0, }; } render(){ return( <View> {this.state.currentpagenum!==0 ? this.getToolbar(): null;} </View> ); } getToolbar(){ return( <ToolbarAndroid /> ); } Looks like you got a typo error you added ; after null this is unneeded also you can get rid of the getToolbar function Instead try: constructor(props) { super(props); this.state = { currentpagenum: 0, }; } render() { return( <View> {this.state.currentpagenum !== 0 ? <ToolbarAndroid /> : null} </View> ); }
