How to get Text component value onPress in react-naive

问题

I'm a new react-native developer. I want to get the value of Text component using onPress and pass it to a function.

<Text onPress={()=>this.display}>Hello World</Text>


display= (text) =>{
    console.log(text);//this should print Hello world
  }

I'm not an expert on React Native. I got some ideas from this Stackoverflow Link

But I think you can set up a ref on the Text component

<Text ref={(elem) => this.textElem = elem} onPress={()=>this.display}>Hello World</Text>

For your event handler, you can do

display = () =>{
    console.log(this.textElem.props.children);//this should print Hello world
}

This method can be used to get text from a text onPress event

 <Text onPress={(event) => console.log(event._dispatchInstances.memoizedProps.children)} >{value}</Text>

回答3:

You need can use the ref attribute to access the button's Text value.

<Text ref='myText'>This is my text</Text>
<Button onPress={()=>this.display(this.refs.myText.props.children)} title='Press Me'/>

//this should print Hello world
display= (text) =>{
    console.log(text);
}

Alternatively, just store it in a variable:

const myText = "This is my text"

<Text onPress={()=>this.display}>{myText}</Text>

display = () => {
     console.log(myText);
}

回答4:

<Text onPress={()=>this.display('Hello World')}></Text>


display= (text) =>{
    console.log(text);//this should print Hello world
  }

Try this
