[英]How to pass id from one component to another component onclick of an element
[英]How to tigger onClick function of another component element
我創建了一個類基礎組件和一個功能組件。 功能組件中有三個按鈕,我將該組件稱為基於類的組件。
功能組件:
function PanelButton(props){
return (
<div>
<Button.Ripple
color="success"
type="submit"
style={{margin:"5px", width:"110px"}}
>
Submit
</Button.Ripple>
<Button.Ripple
color="primary"
id="clearButton"
type="button"
style={{margin:"5px", width:"110px"}}
>
Clear
</Button.Ripple>
<Button.Ripple color="danger" type="button" style={{margin:"5px", width:"110px"}}>
Close
</Button.Ripple>
</div>
)
}
export default PanelButton;
類基礎組件,其中我將功能組件導入到:
import PanelButton from '../../components/customzied/PanelButton';
class TicketNew extends React.Component{
state = {
alertOption:[],
}
clickClear = () => {
console.log("ok");
}
render() {
const rqst = this.state.rquirdSate;
return (
<Card>
<Formik>
{ ({ errors, touched}) => (
<div>
<Form onSubmit={handleSubmit}>
<CardHeader>
<PanelButton />
</CardHeader>
<CardBody>
<Row />
</CardBody>
</Form>
</div>
)}
</Formik>
</Card>
)
}
}
export default TicketNew;
當我單擊功能組件中的button(id = "clearButton")
,我需要在 Class 組件中運行 Click clear 功能。
您可以將clickClear
函數作為道具傳遞給PanelButton
組件。 PanelButton
代碼如下所示,
function PanelButton(props){
return(
<div>
<Button.Ripple color="success" type="submit" style={{margin:"5px", width:"110px"}}>
Submit
</Button.Ripple>
<Button.Ripple color="primary" id="clearButton" onClick={props.onClickCallback} type="button" style={{margin:"5px", width:"110px"}}>
Clear
</Button.Ripple>
<Button.Ripple color="danger" type="button" style={{margin:"5px", width:"110px"}}>
Close
</Button.Ripple>
</div>
)
}
TicketNew
代碼將如下所示,
...
<CardHeader>
<PanelButton onClickCallback={this.clickClear.bind(this)} />
</CardHeader>
...
您可以將onClick
回調處理程序作為道具傳遞給PanelButton
以附加到每個按鈕的onClick
道具。 將clickClear
作為清除按鈕的回調傳遞。
面板按鈕
function PanelButton(props) {
return (
<div>
...
<Button.Ripple
color="primary"
id="clearButton"
type="button"
style={{ margin: "5px", width: "110px" }}
onClick={props.onClear} // <-- attach callback to button's onClick handler
>
Clear
</Button.Ripple>
...
</div>
);
}
新票
class TicketNew extends React.Component {
state = {
alertOption: []
};
clickClear = () => {
console.log("ok");
};
render() {
const rqst = this.state.rquirdSate;
return (
<Card>
<Formik>
{({ errors, touched }) => (
<div>
<Form onSubmit={handleSubmit}>
<CardHeader>
<PanelButton onClear={this.clickClear}/> // <-- pass this.clickClear to onClear prop
</CardHeader>
<CardBody>
<Row></Row>
</CardBody>
</Form>
</div>
)}
</Formik>
</Card>
);
}
}
