I'm having issues with my checkbox, I can't seem to figure out how to get the function to only run when the box is checked. I understand why it is happening but I'm having trouble writing a statement to require the checked state to be true
<Checkbox
disabled={false}
value='MultiEdit'
aria-label="Close"
onChange={() => onChangeValue(item) }
>
</Checkbox>
```

Purpose:
After the keyboard pops up, a shortcut input box with the specified text appears above it. After clicking, the corresponding text such as"https://" or "www." will be appended to the dialog box.
Problem:
I can't get the value in the input dialog in real time and modify it by functions other than keyboard input.
effort made：
The dialog I'm using is referenced from react-native-dialogs。I can't find a way to pass state into the input area of this dialog.
Also didn't find a way to get the value of the live input.
I thought if there are other dialog components that support getting the value of the modified input, but I didn't find one.
Notice that the Dialog.Input of react-native-dialog is just a TextInput. Thus, we can achieve this as usual using the onChangeText callback and the value prop of TextInput.
Here is a minimal example.
const [visible, setVisible] = useState(false);
const [value, setValue] = useState("");
return (
<View style={styles.container}>
<Button title="Show dialog" onPress={() => setVisible(true)} />
<Dialog.Container visible={visible}>
<Dialog.Title>Please enter the url you want to bookmark</Dialog.Title>
<Dialog.Description>
Message - optional
</Dialog.Description>
<Dialog.Input onChangeText={setValue} value={value} />
<Dialog.Button label="Ok" onPress={() => setVisible(false)} />
<Dialog.Button label="Set Text via function" onPress={() => setValue("Hello World")} />
</Dialog.Container>
</View>
);
The state value will be updated while you are typing. You have access to it while the dialog is open. You can set the value manually by using the setValue function of the value state as usual. This can be done while the dialog is open.
Here is a little snack for showcasing.
I want to test a checkbox that has no label. The point is that there are other checkboxes as well so I cant use getByRole.
I have tried to use data-testid, but apparently, it's not working.
How am I supposed to check if that checkbox is checked(toBeChecked())?
<Checkbox
data-testid={item?.id}
key={item?.id}
id={item?.id.toString()}
color="secondary"
checked={item?.checked}
disabled={hasAll}
onChange={(e: React.ChangeEvent<HTMLInputElement>) => {
if (item) {
item.checked = e.target.checked;
setFinalData(updateItemInArray(finalData, {
item,
index,
}));
}
}}
/>
The proper way to do this would be to add an aria-label to your checkbox, so it's announced correctly by screen readers:
<Checkbox inputProps={{ 'aria-label': 'Select row 1' }} />
This way, you'll be able to select it in your tests using getByLabelText.
If you want to use data-testid, you can place it on the checkbox similarly to aria-label:
<Checkbox inputProps={{ 'data-testid': 'checkbox1' }} />
Note that if you're using Typescript, you'd have to cast the inputProps to React.InputHTMLAttributes<HTMLInputElement> as data attributes are not a part of InputHTMLAttributes:
<Checkbox inputProps={{ 'data-testid': 'checkbox1' } as React.InputHTMLAttributes<HTMLInputElement>} />
Hi friends I hope you are doing very well ^^
I am struggling to get a TextInput value when a user enters it in a simple basic form I've created, here is the field :
<TextInput placeholder='latitude' name='lat'/>
<Button style={styles.signIn}
title="Show my entered text"
onPress={() => {
alert(this.state.lat)}}
/>
I tried so many methods to get the value of this field but unfortunately none works.. I am new to react native so I really don't know how can this be done properly (is there any variable I need to define) because in javascript I used to get it only by the GetElementById quite simple right XD
I tried creating a variable exactly bellow the imports like this :
value={this.state.lat}
So I can get the above textInput actual value entered by the user but it isn't working at all and my alert function is not returning anything (I actually don't know if alert() is a react native integrated function or I need to define it from scratch :/), please help I am really lost I tried many solutions on the web but nothing resolves my problem. Thanks in advance
Try this sample code
class Example extends React.Component {
state = { lat: "" };
render() {
return (
<View>
<TextInput
placeholder="latitude"
name="lat"
value={this.state.lat}
onChangeText={(text) => this.setState({ lat: text })}
/>
<Button
style={styles.signIn}
title="Show my entered text"
onPress={() => {
alert(this.state.lat);
}}
/>
</View>
);
}
}
How can I replace the circle checkbox of a DetailsList in office-ui-fabric-react with a normal square CheckBox component? I see onRenderCheckbox so I try something like this:
onRenderCheckbox={(props) => (<Checkbox checked={props.checked} />)}
or
onRenderCheckbox={(props) => (<Checkbox {...props} />)}
I can see the square checkbox but I can't select it.
What it the proper way to do this?
Thanks in advance...
When you render the Checkbox component, it handles the click itself (and thus it won't percolate up to the row so it can toggle selection accordingly), so you need to prevent it with the pointer-events: none style.
onRenderCheckbox(props) {
return (
<div style={{ pointerEvents: 'none' }}>
<Checkbox checked={props.checked} />
</div>
);
}
Check it out here: https://codepen.io/anon/pen/zQXEPr
<Dialog.Container visible={this.state.dialogSendEmailVisible}>
<Dialog.Title>Password Recovery</Dialog.Title>
<Dialog.Input label="Email"></Dialog.Input>
<Dialog.Button label="OK" onPress={this.handleSendEmail} />
</Dialog.Container>
I have this simple dialog, this is being used for password recovery purposes. I am not a FE developer, and I am not finding how can I pass the value typed on Email field to handleSendEmail function. Github and npm pages do not have any example.
Github page: https://github.com/mmazzarolo/react-native-dialog
PS: This can be a very react native basic feature, but I am not findindg a way...
Assuming that the Dialog Inputs/Button extend React Native's own - then you can call:
onSubmitEditing and onChangeText
From the docs:
onSubmitEditing
Callback that is called when the text input's submit button is
pressed. Invalid if multiline={true} is specified.
TYPE REQUIRED
function No
And
onChangeText
Callback that is called when the text input's text changes. Changed
text is passed as an argument to the callback handler.
TYPE REQUIRED
function No
It means something like below:
<Dialog.Input label="Email"
onChangeText={email => this.setState({email})}
value={this.state.email}
onSubmitEditing={
(event) => this.doSomethingWithSubmit(event)
}
>
</Dialog.Input>
UPDATE
So I have tested this, and it works as below - side note - I'm using Typescript so just remove the types ( : string) etc:
In Render
return (
<View>
<View>
<Button onPress={this.showDialog}>
<Text>Show Dialog</Text>
</Button>
<Dialog.Container visible={true}>
<Dialog.Title>Password Recovery</Dialog.Title>
<Dialog.Input label="Email" onChangeText={(email : string) => this.handleEmail(email)}
></Dialog.Input>
<Dialog.Button label="OK" onPress={this.handleSendEmail} />
</Dialog.Container>
</View>
</View>
)
handleEmail:
private handleEmail = (email : string) => {
console.log("email");
console.log(email);
}
Result:
Further
As a side note of this project, I noticed when I used Live reload - that the Dialog was never re-rendered rather, rendered on top of the old Dialog. I would take this into consideration. Perhaps it was my environment, but everything else worked fine.
