[英]How to toggle a Formcontrol as disabled or enabled on different button clicks in React/JS?
[英]How can I toggle a FormControl from disabled to enabled with a button click in Reactjs
我是 React 的新手,剛開始使用 state,所以請與我一起工作。 我還發現了很多類似的問題,但沒有真正解決以下問題:
我有一個禁用 FormControls 的 reactstrap 表單。 當用戶單擊“編輯”按鈕時,需要啟用 FormControls。 據我所知,使用 JSX 應該很簡單,但我嘗試過的任何方法都沒有奏效。 對我來說,這可能只是一個愚蠢的實施錯誤。
class UserProfile extends React.Component {
constructor(props) {
super(props);
this.state = {
editToggle: false,
userName: "Star Lord",
accTier: "Premium",
credit: "95 855 651",
vehicle: "The Milano",
contact: "Echoe Golf Oscar 12.465Ghz"
}
// This binding is necessary to make `this` work in the callback
this.editInputToggle = this.editInputToggle.bind(this);
}
editInputToggle() {
this.setState(prevState => ({
editToggle: !prevState.editToggle
}));
}
onValueChange = (e) => {
this.setState({ fullName: e.target.value });
};
render() {
const { editToggle } = this.state;
// We need give the components function a return statement.
return (
/* The Component can only return one parent element,
while parent elements can have many children */
<div className='profileDetails'>
{/* Bootstrap Form is used for the form
Bootstrap Button is used for the edit button */}
<Form id='formProfile'>
<Form.Group className="mb-3" controlId="formProfileDetails">
<Form.Label>US3RNAME:</Form.Label>
<Form.Control type="text" value={this.state.userName}
onChange={this.onValueChange} className='user-info' />
<Form.Label>ACC0uNT TI3R:</Form.Label>
<Form.Control disabled type="text" value={this.state.accTier} onChange={this.onValueChange} className='user-info' />
<Form.Label>CR3DiT:</Form.Label>
<Form.Control disabled type="text" value={this.state.credit} onChange={this.onValueChange} className='user-info' />
<Form.Label>R3GiSTERED VEHiCL3:</Form.Label>
<Form.Control disabled type="text" value={this.state.vehicle} onChange={this.onValueChange} className='user-info' />
<Form.Label>C0NTACT D3TAiLS:</Form.Label>
<Form.Control disabled type="text" value={this.state.contact} onChange={this.onValueChange} className='user-info' />
</Form.Group>
<Button variant="light" size="sm" className='p-2 m-4 headerBtn' onClick={ () => this.editInputToggle(editToggle) }>
Edit
</Button>
</Form>
</div>
);
}
}
我需要做什么才能將“禁用”更改為“”?
要啟用 FormControl,
<Form.Control disabled={!this.state.editToggle} type="text" value={this.state.accTier} onChange={this.onValueChange} className='user-info' />
嘗試用以下行替換“禁用”: disabled={this.state.editToggle? “真假”}
