When Select isSearchable and device is mobile I would like the keyboard to be in number mode. Is this possible? Thanks
You have to overwrite the Input component using the components framework and set the pattern prop to only allow digits if the current device is mobile.
The pattern prop (or rather attribute) on input elements checks the value of the input for input validation. With the right pattern, it controls the type of keyboard you get on mobile devices. \d* is a regex pattern that will only allow digits into the input.
const Input = (props) => <components.Input {...props} pattern={somehowCheckForMobile() ? "\\d*" : undefined} />;
<Select
{ ... }
components={{
Input
}}
/>

I have a Google places autocomplete input and need to populate address related fields based on selected place as below:
<GPAutocompleteInput
source="address_full"
placeholder="Find address"
onPlaceSelected={onPlaceSelected}
gaOptions={{ types: ["address"] }}
/>
<TextInput source="address_street" disabled label="Ulica" />
<TextInput source="address_postcode" disabled label="Kod pocztowy" />
<TextInput source="address_city" disabled label="Miasto" />
Now I would like the 3 disabled inputs to be filled in with the address components from the selected place but can't figure out how to do this.
I've tried providing initialValues to the SimpleForm component and this works ok in the create view but not in the edit because those fields already have a value the values are not being updated.
react-final-form provides a simple hook allowing me to change values
import { useForm } from "react-final-form";
const form = useForm();
form.change("address_city", components?.address_city);
There may be a better way as this requires building a custom component to use form context required by the hook.
In react native navigation I use a custom icon, I want to be able to change this icon depending on if the user is in dark mode or normal mode.
The challenge I'm having is passing in the value of the path dynamically. I want to call a method inline that returns the file name of the icon.
<Marker
coordinate={this.state.region}
image={require("./" + {chkDarkMode()} + ".png")}
/>
How can I dynamically set the image? I've seen the conditional if length is equal to zero, but that example doesn't allow for multiple possible images.
Unfortunately, that's not allowed.
You can instead call require conditionally:
const image = darkMode ? require("./darkModeImage.png") : require("./lightModeImage.png")
One way to do this:
getImagePath = () => {
return `./${chkDarkMode()}.png`
}
<Marker
coordinate={this.state.region}
image={getImagePath()}
/>
By default when the react-select is rendered i see "Select..." on the component. I want to see "Search ...".
Looking at the docs, I am assuming I need to use the noOptionsMessage prop, which is documented as:
noOptionsMessage function = () => undefined
Text to display when there are no options
({
inputValue string required
}) => One of<
react.Node,
null
>
I did not really understand that bit of the docs. E.g. this prop seems to be a function. So, I have been trying variations including following without success:
<AsyncSelect
cacheOptions
defaultOptions={[]}
loadOptions={handleLoadOptions}
onChange={handleChange}
noOptionsMessage={()=> "Search..."}
/>
So, what is the solution?
Add placeholder to the AsyncSelect.
<AsyncSelect
cacheOptions
defaultOptions={[]}
loadOptions={handleLoadOptions}
onChange={handleChange}
placeholder='Search...'
/>
Common props you may want to specify include:
autoFocus - focus the control when it mounts
className - apply a className to the control
classNamePrefix - apply classNames to inner elements with the given prefix
isDisabled - disable the control
isMulti - allow the user to select multiple values
isSearchable - allow the user to search for matching options
name - generate an HTML input with this name, containing the current value
onChange - subscribe to change events
options - specify the options the user can select from
placeholder - change the text displayed when no option is selected
value - control the current value
I know that the practice of react native is to use onChangeText for change value as follow.
<TextInput
onChangeText = {(text)=> this.setState({myText: text})}
value = {this.state.myText}
/>
However, I wonder if i could do something like this. To summarise, I want to loop through all the TextInput and get the ref and value. I just want to do things in javascript way as follow. Is that possible to be done?
<TextInput id="id1" ref={ref => (this.remark = ref)} />
<TextInput id="id2" ref={ref => (this.remark1 = ref)} />
onSubmit = () => {
forEach(TextInput in component) {
console.log(TextInput.id) <- note id is custom property
console.log(TextInput.refName)
console.log(TextInput.value)
}
}
Yes, but I wouldn't recommend this approach. You could simply create an array of refs and loop through it in your onSubmit function.
forEach(TextInput in component) {
This is not possible in any javascript environment (not only because forEach and for..in syntax is different but also you can't expect to be able to loop over component elements by type (?) and get them)
What you want to do is not javascript way but old style browser way:
there are no ids in react-native
technically you could get uncontrolled TextInput's value like you would do in plain react in browser environment (via this.textInputRef._lastNativeText) but it's discouraged in react-native, most likely because because instead of DOM react native has to render to native views which all differ depending on the platform (iOS, Android, Windows, etc) but have to work the same
So it's not only impossible in react native but in plain react as well. It looks to me like you want to create a form, and sooner or later you will find out that you want validation or transformation on your inputs and switch back to controlled components anyway
I need to disable emojis for my react native keyboard app. When my keyboard appear, the emoji icon is visible and i need to make it unavailable to prevent user to insert emojis in texts.
Any suggestions ?
The exact way to disable emoji is to set 'ascii-capable' for iOS and 'visible-password' for Android to TextInput Props keyboardType.
<TextInput
keyboardType={Platform.OS === 'ios' ? 'ascii-capable' : 'visible-password'}
/>
This is what I got when attempting this problem:
the keyboardType="ascii-capable" does not work on Android because it is specific to iOS only accordding to https://facebook.github.io/react-native/docs/textinput#keyboardtype
using keyboardType="email-address" does not hide the emoji button in every keyboard on Android
My solution to the above limitations was to remove any emoji character that the might be entered. To do that, I did the following:
Search for a regex that covers most of the emoji unicodes. After trying a number of regex, I ended up using the one this https://github.com/mathiasbynens/emoji-regex. It's not perfect but it covers most emojis.
Create a function that runs every time a new value is entered
Use the function in the Text Input value prop
Function:
const removeEmojis = (string) => {
// emoji regex from the emoji-regex library
const regex =

You can try with the keyboardType="ascii-capable" in the TextIput, in order to hide the emojis option on the keyboard, like:
<TextInput keyboardType="ascii-capable" ... />
Let me know if this works for you.
TextInput has a keyboardType property that will let you fix this issue. But android and ios handle it differently. This is what worked for me with both platforms.
<TextInput keyboardType={Platform.OS === 'android' ? 'email-address' : 'ascii-capable'} ... />
