我正在使用Redux表单来创建React.js中的表单,我的表单中有一个自定义的谷歌地图组件,我想将纬度和经度绑定到我的表单中。
表单
import React from 'react';
import { Field, reduxForm } from 'redux-form';
const SimpleForm = props => {
const { handleSubmit, pristine, reset, submitting } = props;
return (
<form onSubmit={handleSubmit}>
<div className="position-relative form-group">
<label>First Name</label>
<div>
<Field
name="firstName"
component="input"
type="text"
placeholder="First Name"
className="form-control"
/>
</div>
</div>
<Field name = 'eventLocation'
component = {MyParentComponentWrapper} />
</form>
);
};
export default reduxForm({
form: 'simple', // a unique identifier for this form
})(SimpleForm);
而我的 MyParentComponentWrapper 代码如下:
import React from 'react';
import { compose, withProps, lifecycle } from 'recompose';
import { withScriptjs, withGoogleMap, GoogleMap, Marker } from 'react-google-maps';
const MyMapComponent = compose(
withProps({
googleMapURL:
'https://maps.googleapis.com/maps/api/js?key=AIzaSyCYSleVFeEf3RR8NlBy2_PzHECzPFFdEP0&libraries=geometry,drawing,places',
loadingElement: <div style={{ height: `100%` }} />,
containerElement: <div style={{ height: `400px` }} />,
mapElement: <div style={{ height: `100%` }} />,
}),
lifecycle({
componentWillMount() {
const refs = {};
this.setState({
position: null,
onMarkerMounted: ref => {
refs.marker = ref;
},
onPositionChanged: () => {
const position = refs.marker.getPosition();
console.log(position.toString());
},
});
},
}),
withScriptjs,
withGoogleMap
)(props => (
<GoogleMap defaultZoom={8} defaultCenter={{ lat: -34.397, lng: 150.644 }}>
{props.isMarkerShown && (
<Marker
position={{ lat: -34.397, lng: 150.644 }}
draggable={true}
ref={props.onMarkerMounted}
onPositionChanged={props.onPositionChanged}
/>
)}
</GoogleMap>
));
class MyParentComponentWrapper extends React.PureComponent {
state = {
isMarkerShown: false,
};
render() {
return (
<div>
<MyMapComponent isMarkerShown={true} />
</div>
);
}
}
export default MyParentComponentWrapper;
这个组件将在用户拖动标记时,通过 console.log 打印经纬度值
如何将 console.log
的值传递到 redux-form 中?
有人能否建议一种解决方案?
position
放入你的 store 中,并将其作为prop
传递到你的表单中,然后只需在字段上设置value
prop 即可。 - NoxelNyxredux-form
