How to get the style name and state name of a clicked element in React Native? - react-native

Question

In the following, first example how do I check if the clickable element TouchableWithoutFeedback has the style named EntryBlock1?
render() {
return (
<TouchableWithoutFeedback style={styles.EntryBlock1} onPress={() => this.CheckIfHasStyles()}>
<View style={styles.redundantWrapperNumber1}>
<Text style={styles.redundantWrapperNumber2}>Click To Test For Style</Text>
</View>
</TouchableWithoutFeedback>
<TouchableWithoutFeedback style={styles.EntryBlock2} onPress={() => this.CheckIfHasStyle()}>
<View style={styles.redundantWrapperNumber1}>
<Text style={styles.redundantWrapperNumber2}>Click To Test For Style</Text>
</View>
</TouchableWithoutFeedback>
); // end return
} // end render
In the 2nd example, how can I check if TouchableWithoutFeedback has the state name EntryBlock1 ?
constructor (props) {
super(props);
this.state = {
EntryBlock1: [styles.entryBlockButton, styles.entryBlockButtonMin],
EntryBlock2: [styles.entryBlockButton, styles.entryBlockButtonMax],
}
}
render() {
return (
<TouchableWithoutFeedback style={this.state.EntryBlock1} onPress={() => this.CheckIfHasStateName()}>
<View style={styles.redundantWrapperNumber1}>
<Text style={styles.redundantWrapperNumber2}>Click To Test For Style</Text>
</View>
</TouchableWithoutFeedback>
); // end return
What I've Tried
Different stuff along the lines of the following..
CheckIfHasStyles =()=> {
var object = this.state;
var stringifiedObject = JSON.stringify(object);
var slicedObject = stringifiedObject.slice(2, 13);
if (slicedObject === 'EntryBlock1') {
alert('success');
} else {
alert('failure');
}
}
.. which actually works for one very specific example, but not when I have multiple state names as this.state gets all of them in one object and not just the state of the element clicked.
Note: My question is solely about getting attributes and their values. It is to help me develop a style of toggling styles on elements but I am only looking for attribute stuff in these answers as I would like to use attributes, if possible, for more than just toggling in the future.

You can pass it as parameter to your function directly like this:
render() {
return (
<TouchableWithoutFeedback style={styles.EntryBlock1} onPress={() => this.CheckIfHasStyles('EntryBlock1')}>
<View style={styles.redundantWrapperNumber1}>
<Text style={styles.redundantWrapperNumber2}>Click To Test For Style</Text>
</View>
</TouchableWithoutFeedback>
<TouchableWithoutFeedback style={styles.EntryBlock2} onPress={() => this.CheckIfHasStyle('EntryBlock2')}>
<View style={styles.redundantWrapperNumber1}>
<Text style={styles.redundantWrapperNumber2}>Click To Test For Style</Text>
</View>
</TouchableWithoutFeedback>
);
}
and check if you are receiving any parameter in your function and do what you want
based on If-else condition
