React Native appending Text component inside of another Text Component

12,327

Ok, check out what I have below. I've essentially created an array of text values that are place in between two <Text> fields, and when the insertText function is called, it pushes a new text element to the array, then resets the state of the array to the te property:

  getInitialState: function() {
        return {
         te: [<Text>Yo</Text>],
         index:1
        }
  },

  insertText: function() {
    this.state.te.push(
        <Text>Text number {this.state.index}</Text>
    )
    this.setState({
        index: this.state.index + 1,
        te: this.state.te
    })
  },

  render: function() {

    var MyText = function(t) {
      return(
        <Text>
          {t}
        </Text>
      )           
    }

    return (
      <View style={styles.container}>
            {MyText(this.state.te)}
        <TouchableHighlight onPress={ () => this.insertText() } style={{ marginTop:20, height:60, flexDirection: 'row', backgroundColor: '#ededed', justifyContent: 'center', alignItems: 'center' }}>
            <Text style={{ fontSize: 22 }}>Add Text</Text>
        </TouchableHighlight>
      </View>
    );

I've set up the full working project here. Full code is also posted below.

'use strict';

var React = require('react-native');
var {
  AppRegistry,
  StyleSheet,
  Text,
  View,
  TouchableHighlight
} = React;

var SampleApp = React.createClass({

  getInitialState: function() {
        return {
       te: [<Text>Yo</Text>],
         index:1
    }
  },

  insertText: function() {
    this.state.te.push(
        <Text>Text number {this.state.index}</Text>
    )
    this.setState({
        index: this.state.index + 1,
      te: this.state.te
    })
  },

  render: function() {

    var MyText = function(t) {
      return(
        <Text>
          {t}
        </Text>
      )           
    }

    return (
      <View style={styles.container}>
            {MyText(this.state.te)}
        <TouchableHighlight onPress={ () => this.insertText() } style={{ marginTop:20, height:60, flexDirection: 'row', backgroundColor: '#ededed', justifyContent: 'center', alignItems: 'center' }}>
            <Text style={{ fontSize: 22 }}>Add Text</Text>
        </TouchableHighlight>
      </View>
    );
  }
});

var styles = StyleSheet.create({
  container: {
    flex: 1,
    marginTop: 60
  }
});

AppRegistry.registerComponent('SampleApp', () => SampleApp);

    I have a text component

    <Text ref="text" style{...}>{this.state.te}</Text>
    

    and I would like to insert and append other <Text></Text>

    so when the event fires on a button I want it to insert a new <Text></Text> to look like this

    <Text ref="text" style{...}>
       <Text ref="text" style{...}>first</Text>
       <Text ref="text" style{...}>second</Text>
       <Text ref="text" style{...}>third</Text>
    </Text>
    

    this is what my event looks like

    insertText(){
     this.setState({te: this.state.te + <Text style={...}>{this.refs.newText.props.value}</Text>})
    

    }

    when I do this all it renders is "[object object]" inside of the Text Component

    if I use

     this.setState({te: <Text style={...}>{this.refs.newText.props.value}</Text>})
    

    it will render the text just fine with a single <Text></Text> element.

    any help would be appreciated. Thanks.

    Edit:

    this.state.te holds te: <Text></Text>
