I would like to select an item from the dropdown list and would like to set the state of staffId to it. I would like dropdown to show the name, but after I select the name, set the staffid to state. I would also like to achieve this without hardcoding the values in an if-else loop as I have thousands of data to work with.
This is the data fetched from WebAPI and stored in a state called items
this.setState({
items: dataSource
staffId: ''
})
This state of items will be this.
[
{"departmentName":"HOUSE","employeeName":"TEST1", "staffId" : "00001"},
{"departmentName":"HOUSE","employeeName":"TEST2", "staffId" : "00002"},
{"departmentName":"HOUSE","employeeName":"TEST3", "staffId" : "00003"}
]
I have created a dropdown in react native with just the emplyeeName. I am using react-native-material-dropdown for the library. I would like to show employeeName but when a user select a name, get an id instead
let staff = this.state.listOfEmployees.map(item => ({
value: item.employeeName
staffId: item.staffId
}));
<Dropdown
label='Staff Name'
baseColor='#0079b5'
data={staff}
selectedValue={value}
onChangeText={(staffId) => this.onChangeName(staffId)}
/>
Here in this function, I would like to set the state of staffId to the staffId of the selected value.
onChangeName = (staffId) => {
//set the state of staffId to the staffId of the selected value.
//For Example, if AUNG THU 1 is selected, the state of staffId is '00001'.
this.setState({
staffId: staffId
})
}
You can do this using the valueExtractor
and labelExtractor
props. Should look something like this:
<Dropdown
label='Staff Name'
baseColor='#0079b5'
data={staff}
selectedValue={value}
valueExtractor={({ staffId }) => staffId}
labelExtractor={({ employeeName }) => employeeName}
onChangeText={(staffId) => this.onChangeName(staffId)}
/>
