I'm new to react-native and I have an input where I can choose multiple days of a week, if I click on a day which is alreadyAdded the day is removed from selectedDays array, however when I click on a day I get the following error:
TypeError: selectedDays.includes is not a function. (In selectedDays.includes(index+1) selectedDays.includes is undefined
My code:
const [ dayOptions, setDayOptions ] = useState([ 'Lunes','Martes','Miercoles','Jueves','Viernes','Sabado','Domingo']);
const [ selectedDays, setSelectedDays ] = useState([1]);
const clickedDay = (id)=>
{
const index = selectedDays.indexOf(id);
if (index > -1)
{
setSelectedDays(selectedDays.splice(index, 1));
}
else
{
setSelectedDays(selectedDays.push(id));
}
}
<View style={{ width:'100%',height:45,flexDirection:'row',alignItems:'center',flexWrap:'nowrap', justifyContent:'space-between' }}>
{dayOptions.map((option,index) => {return (
<TouchableOpacity key={option.title} onPress = {() => {clickedDayOptions(index+1) }} style={{ width:'13.2%', height:'100%', flexDirection:'row', alignItems:'center',justifyContent:'center', borderRadius:5,borderWidth:1, borderColor:'rgba(0,0,0,0.2)', ...selectedDays.includes(index+1) ? { backgroundColor: 'rgb(255,52,89)' } : { backgroundColor:'white' }, }}>
<Text style={{ fontWeight:'bold',fontSize:14, ...selectedDays.includes(index+1) ? { color: 'white' } : { color:'rgb(68,68,68)' }, }}>{ option }</Text>
</TouchableOpacity>)
})}
</View>
I tried changing includes for indexOf() > 1 and I get the same error, I usually get this when it's not an array but I defined selectedDays as an array in hooks...
setSelectedDays(selectedDays.push(id)); Generally Array.prototype.push will return the length of the array after push operation is done, so here we are making Array to number so that you are getting indexOf, includes is not a function error because it's a number type
Try like below
const clickedDay = (id) => {
const index = selectedDays.indexOf(id);
if (index > -1) {
selectedDays.splice(index, 1)
setSelectedDays([...selectedDays]);
} else {
setSelectedDays([...selectedDays, id]);
}
};
const clickedDay = (id) => {
const index = selectedDays.indexOf(id);
if (index > -1) {
const days = selectedDays.filter((idx) => idx !== id);
setSelectedDays(days);
} else {
setSelectedDays([...selectedDays, id]);
}
};
I have a component that is giving me the following issues:
TEST STEPS:
Login to Mobile.
On the Activity Feed, answer the first Get Involved question.
Scroll to the last Get Involved question and answer it.
Scroll back to the first Get Involved question that was answered.
EXPECTED RESULTS:
The answer for the first Get Involved question should still be selected.
ACTUAL RESULTS:
It is not selected.
So it seems the issue is the callback that updates some state on the parent, but the parent is not passing the yes/no prop to this component and it's unmounting to spare me rendering.
On the backend, in the database, the answers are being recorded, but it's not persisting in the UI. I noticed that the helper functions below, specifically the this.props.onPress() return undefined.
class GetInvolvedFeedCard extends PureComponent {
static propTypes = {
onPress: PropTypes.func.isRequired,
style: PropTypes.oneOfType([PropTypes.number, PropTypes.object]),
title: PropTypes.string.isRequired
};
constructor(props) {
super(props);
const helper = `${
this.props.title.endsWith("?") ? "" : "."
} Your NFIB preferences will be updated.`;
this.state = {
noSelected: false,
yesSelected: false,
helper
};
}
_accept = () => {
this.setState({ yesSelected: true, noSelected: false }, () => {
this.props.onPress(true);
});
};
_decline = () => {
this.setState({ noSelected: true, yesSelected: false }, () => {
this.props.onPress(false);
});
};
render() {
return (
<Card style={this.props.style}>
<View style={feedContentStyles.header}>
<View style={feedContentStyles.contentType}>
<Text style={feedContentStyles.title}>{"GET INVOLVED"}</Text>
</View>
</View>
<Divider />
<View style={feedContentStyles.content}>
<View style={styles.content}>
<Text style={styles.blackTitle}>
{this.props.title}
<Text style={styles.italicText}>{this.state.helper}</Text>
</Text>
</View>
<View style={styles.footer}>
<TouchableOpacity onPress={this._decline}>
<Text
style={[
styles.btnText,
styles.noBtn,
this.state.noSelected ? styles.selected : null
]}
>
{"NO"}
</Text>
</TouchableOpacity>
<TouchableOpacity onPress={this._accept}>
<Text
style={[
styles.btnText,
this.state.yesSelected ? styles.selected : null
]}
>
{"YES"}
</Text>
</TouchableOpacity>
</View>
</View>
</Card>
);
}
}
So it appears that the state is being managed by the parent component as opposed to Redux.
What is unclear is, whether or not it is unmounting the component that defines onPress. It sounds like it is.
Just scrolling, so there is an activity feed composed of cards some of them render boolean type questions
do you want to get involved? no yes
When a user selects either response, then scrolls down a certain amount and then scrolls back up to that same question, it's like the user never answered it. I noticed when the user selects NO, the this.props.handleUpdateGetInvolved({ involved: items }) from _handleGetInvolved function is not fired only when the user selects YES. Referring to this:
_handleGetInvolved = (response, entity) => {
if (response !== entity.IsSelected) {
const isTopic = entity.Category !== "GetInvolved";
const items = [
{
...entity,
IsSelected: response
}
];
if (isTopic) {
this.props.handleUpdateTopics({ topics: items });
} else {
this.props.handleUpdateGetInvolved({ involved: items });
}
}
};
the helper functions themselves for each answer always returns undefined inside the GetInvolvedFeedCard component:
_accept = () => {
this.setState({ yesSelected: true, noSelected: false }, () => {
this.props.onPress(true);
console.log(
"this is the accept helper function: ",
this.props.onPress(true)
);
});
};
_decline = () => {
this.setState({ noSelected: true, yesSelected: false }, () => {
this.props.onPress(false);
console.log(
"this is the decline helper function: ",
this.props.onPress(false)
);
});
};
render() {
return (
<Card style={this.props.style}>
<View style={feedContentStyles.header}>
<View style={feedContentStyles.contentType}>
<Text style={feedContentStyles.title}>{"GET INVOLVED"}</Text>
</View>
</View>
<Divider />
<View style={feedContentStyles.content}>
<View style={styles.content}>
<Text style={styles.blackTitle}>
{this.props.title}
<Text style={styles.italicText}>{this.state.helper}</Text>
</Text>
</View>
<View style={styles.footer}>
<TouchableOpacity onPress={this._decline}>
<Text
style={[
styles.btnText,
styles.noBtn,
this.state.noSelected ? styles.selected : null
]}
>
{"NO"}
</Text>
</TouchableOpacity>
<TouchableOpacity onPress={this._accept}>
<Text
style={[
styles.btnText,
this.state.yesSelected ? styles.selected : null
]}
>
{"YES"}
</Text>
</TouchableOpacity>
</View>

This is what the Get Involved card looks like:
So when the user clicks NO or YES, then scrolls that card away from view, the expectation is when they scroll that card back into view NO or YES, whichever one selected, should still be there.
Also, the answer selected only disappears when the user scrolls all the way to the bottom of the activity feed and then back up, but if the user only scrolls halfway through the activity feed cards and returns to this Get Involved card, the answer selected does not go away.
I believe the below SO article answer is exactly what is happening to me:
React Native - FlatList - Internal State.
So it seems the answer here would be to pass the answer from the application state as a prop and render based on that prop, and not the internal state of the card but I am not entirely sure what that looks like or how to put it together.
constructor(props) {
super(props);
// const helper = `${
// this.props.title.endsWith("?") ? "" : "."
// } Your NFIB preferences will be updated.`;
this.state = {
noSelected: false,
yesSelected: false,
helper
};
}
_accept = () => {
this.setState({ yesSelected: true, noSelected: false }, () => {
this.props.onPress(true);
});
};
_decline = () => {
this.setState({ noSelected: true, yesSelected: false }, () => {
this.props.onPress(false);
});
};
with:
this.state = {
// noSelected: false,
// yesSelected: false,
// helper
cardSelectedStatus: []
};
with the idea of then implementing cardSelectedStatus in my mapStateToProps
function mapStateToProps(state) {
return {cardSelectedStatus: state.};
}
but then I realized I am not sure what I am passing in as there are no action creators involved in this component, therefore no reducers
so can I use mapStateToProps if there is no action creator/reducer involved in this component?
utilizing mapStateToProps is the only way I know or its the way with the most experience I have in passing the user's input from the application state as a prop and render based on that prop, and not the internal state.
I can guess the problem. The problem is you are using something like FlatList. It will recreate the card every time you scroll it over screen, then scroll back.
So there are 2 ways to fix it:
Using ScrollView. It won't recreate cards
Move card states out of the Card component. Move them to List state. So in List state you will have something like:
this.state = {
cardSelectedStatus: [], // array [true, false, true, ...]. Mean card 0: selected, card 1: no selected,...
...
};
Then you can pass state to each card
So after several weeks of hammering away at this and posting the above question, here is what I finally honed in on:
By default the data for the preference is set to isSelected: false in the Redux state.
If I hit Yes, the Redux state is updated. This changes the isSelected to true.
If I hit No after hitting Yes, the Redux state is NOT updated, it stays isSelected: true.
So based on this, because isSelected does not have a neutral value, that is, starts out as false, which would equate to No, I cannot rely on Redux state for rendering the selection, which could have solved this.
Instead, in the interest of time, the only solution I could think of with much input from others includint tuledev, was to set <FlatList windowSize={500} />.
This is not an elegant solution but it will get FlatList to behave more like ScrollView in that preserve all the components so my component state will not get wiped out when a user scrolls to far away from it. This works without actually replacing it to ScrollView since there are properties and methods with FlatList that would not work by just dropping it into ScrollView same as it is in FlatList, for example, there is no renderItem property in ScrollView.
The below code shows the array of duplicate data's , But I need a Unique data's from the array.
I tried many steps, but I can't find the solution:
See the below image of the output of duplicate received
JS File
export default class App extends React.Component {
constructor(props) {
super(props);
this.state = {
storage: [],
};
this.renderData = this.renderData.bind(this);
}
renderData({ item, index }) {
const datas = Array.from(new Set(item.category));
return (
<View>
<Text>{datas}</Text>
</View>
);
}
componentDidMount() {
fetch('http://myjsonpage', {
method: 'post',
headers: {
Accept: 'application/json',
'Content-Type': 'application/json',},
body: JSON.stringify({
token: 'XXXXXX',

} else {
this.setState({ storage: [] });
}
});});}

Thanks in Advance..!!
There's many ways to remove duplicates from array, Use Sets to remove your duplicates.
const data = ['Renewal', 'Subscriptions', 'Subscriptions', 'Subscriptions', 'Renewal', 'Renewal']
const unique = new Set(data);
const uniqueData = [...unique]; // array
const data = ['Renewal', 'Subscriptions', 'Subscriptions', 'Subscriptions', 'Renewal', 'Renewal']
const uniqueData = [...new Set(data)];
console.log(uniqueData);
if (responseData.status === 1) {
this.setState({ datas: [...new Set(responseData.data)] }) ;
} else {
this.setState({ storage: [] });
}
I have a problem about how to print a value,in a function, in react-native.
Basically I have a function that research in the DB some values, and I should print this values.
findUtente(cf) {
let params = {};
console.log(cf)
params = {
"Person.FiscalCode": cf
};
global.utente.db.localdb().find({
selector: params
})
.then(response => {
let utente = response.docs[0];
console.log ("utente: " + utente)
utente.Person.FirstName;
console.log ("utente.Person.FirstName: " + utente.Person.FirstName)
})
//.... catch...}); }
render() {
{this.findUtente(this.props.cf)}
return (
<View style={style.container}>
<View style={style.page}>
<KeyboardAwareScrollView>
<Text style={visualProfilo.text}>Name:</Text>
<Text style={visualProfilo.text1}>{Stamp Here the FirstName}</Text>
The value in the console log is print in the right way.
How can I print that value?
Thank you
You can use componentDidMount to call the method then you can set the value to state and then update value using setState then render state value
example:
state = {
FirstName: ''
}
componentDidMount(){
this.findUtente(this.props.cf)
}
findUtente(cf) {
let params = {};
console.log(cf)
params = {
"Person.FiscalCode": cf
};
global.utente.db.localdb().find({
selector: params
})
.then(response => {
let utente = response.docs[0];
this.setState({FirstName: utente.Person.FirstName})
})
//.... catch...}); }
render() {
return (
//everything remains same
<Text style={visualProfilo.text1}>{this.state.FirstName}</Text>
)
}
In here I have two problems. First is I'm trying to fetch dome data from my api and then pass this data to modal upon tapping a button. I have tried to use "state" and then declare that state like;
constructor(props){
super(props)
this.state = {
tbl: [],
tbl_no: null,
}
}
fetchTblOccpd = async () => {
const response = await fetch('http://192.168.***.***:****/PndngVRoutes/Occupied/');
const json = await response.json();
this.setState({ tbl: json })
this.setState({ tbl_no: json })
}
render() {
return (
.....
<PndModal
modalVisible = { this.state.modalVisible }
setModalVisible = { (vis) => { this.setState({ modalVisible: vis }) }}
tbl_no = { this.state.tbl_no }
/>
)
}
But this didn't work. I'm targeting to fetch a data and pass it to my Modal.
Sample
My Second question is after passing some data to Modal, I'm targeting to navigate to another screen/view from my modal.
here's my code
export default class PndModal extends Component {
constructor(props) {
super(props);
this.state = {
pnd_Data: [],
modalVisible: props.modalVisible,
};
}
componentWillReceiveProps(nextProps) {
this.setState({
modalVisible: nextProps.modalVisible,
tbl_no: nextProps.tbl_no, //This is the data I'm trying to pass.
})
}
fetchOrdered = async () => {
const response = await fetch("http://192.168.254.***:****/PndngVRoutes/PendingView/" + this.state.tbl_no);
const json = await response.json();
this.setState({ pnd_Data: json })
}
componentDidMount() {
this.fetchOrdered();
}
_onPressItem = () => {
this.setState({
modalVisible: false,
});
}
render() {
return (
<Modal>
<View>
<View>
<View>
<Text>Table No: { this.state.tbl_no }</Text>
<FlatList
data = {this.state.pnd_Data}
numColumns = { 2 }
keyExtractor={(item, index) => index.toString()}
renderItem = {({ item }) =>
<View>
<Text>{ item.menu_name }</Text>
</View>
}
/>
<TouchableOpacity
onPress = { () => this.props.navigation.navigate('pend') }> // This is my navigation code
<Text>Add Order</Text>
</TouchableOpacity>
</View>
</View>
</View>
</Modal>
)
}
}
Hello Am not too use to react native but i think is must be the same as react , for the solution to your problem , i think you should use reusable component . then create then pass your data as a props.
Here is an example in react.
//My reusable component
const Modal=(props) =>{
return (
<div>
{props.data}
</div>
);
}
}
Then you call your reusable component then pass the results from the api to it.
<Modal
data ={this.state.pnd_Data}
/>
for the second question you can just add link that will navigate you .... there will be no problem for that .
you can read about reusable component here
https://itnext.io/react-component-class-vs-stateless-component-e3797c7d23ab
