这是this问题的补充问题。
我想做的事情:
我有一个按钮可以点击我的当前位置。此按钮还应该使用值填充<Field>
组件,以便稍后提交。
发生了什么:
我的Field
组件未发现任何更改,因此无法提交该值。 redux状态没有被填充,我认为它正在发生,因为Field
onchange事件没有被触发。我尝试将状态直接设置为onChange
,但它不起作用(可能不应该)。
感谢您帮助这个菜鸟人。
export class GetLocation extends Component{
constructor(){
super();
this.state = {
latitude: '',
longitude: ''
};
this.getMyLocation = this.getMyLocation.bind(this);
}
componentWillMount(){
console.log('mon')
this.getMyLocation();
}
getMyLocation = () => {
const location = window.navigator && window.navigator.geolocation;
if (location) {
location.getCurrentPosition((position) => {
this.setState({
latitude: position.coords.latitude,
longitude: position.coords.longitude,
})
}, (error) => {
this.setState({ latitude: 'err-latitude', longitude: 'err-longitude' })
})
}
}
render(){
const { latitude, longitude } = this.state;
return(
<div>
<p>Your location is </p>
<Field
name="latitude"
type="text"
component="input"
onChange={this.state.latitude}
/>
{/*<input name="latitude" value={this.state.latitude} />*/}
{/*<input type="text" name="longitude" value={longitude} />*/}
<button type="button" onClick={this.getMyLocation}>Get Geolocation</button>
</div>
);
}
}
这是我的wizardform
代码:
import React from "react";
import { Field, reduxForm, FormSection } from "redux-form";
import validate from "../middleware/validate";
import { Address, Camp, GetLocation } from "../components/renderField";
import {connect} from "react-redux";
const renderError = ({ meta: { touched, error } }) =>
touched && error
? <span>
{error}
</span>
: false;
let WizardFormSecondPage = props => {
const { handleSubmit, previousPage} = props;
return (
<form onSubmit={handleSubmit} className="form-horizontal">
<div className="panel">
<div className="form-group">
<label className="control-label col-sm-2" htmlFor="address">
Location
</label>
<div className="col-sm-10">
<p className="help-block lead">Write your address below</p>
<p className="help-block">You can add more than one. Add as many as you can.</p>
<div className="row">
<div className="col-sm-12">
<p className="label-lead">Own Address</p>
<FormSection name="ownAddress" component={Address}>
<Address />
</FormSection>
<p className="label-lead">Host Address</p>
<FormSection name="hostAddress" component={Address}>
<Address />
</FormSection>
<p className="label-lead">Camp</p>
<FormSection name="camp" component={Camp}>
<Camp />
</FormSection>
<p className="label-lead">Location Coordinates</p>
<FormSection name="location" component={GetLocation}>
<GetLocation />
</FormSection>
</div>
</div>
</div>
</div>
<div className="form-group">
<label className="control-label col-sm-2">Household</label>
<div className="col-sm-10">
<p className="help-block lead">Who are you in your household?</p>
<p className="help-block">It can be a husband, wife, children or grandparent. Select the appropriate one. </p>
<Field name="houseHold" component="select" className="form-control">
<option />
<option value="1">None</option>
<option value="2">Husband</option>
<option value="3">Spouse</option>
<option value="4">Child-1</option>
<option value="5">Child-2</option>
</Field>
</div>
</div>
<div>
<button type="button" className="previous" onClick={previousPage}>
Previous
</button>
<button type="submit" className="next">
Next
</button>
</div>
</div>
</form>
);
};
export default reduxForm({
form: "wizard", // <------ same form name
destroyOnUnmount: false, // <------ preserve form data
forceUnregisterOnUnmount: true, // <------ unregister fields on unmount
validate
})(WizardFormSecondPage);
答案 0 :(得分:0)
我会使用方法change
设置Redux商店中纬度字段的值,因此getMyLocation
将如下所示:
getMyLocation() {
const location = window.navigator && window.navigator.geolocation;
if (location) {
location.getCurrentPosition(position => {
this.props.change("latitude", position.coords.longitude);
});
}
}
你的领域将是:
<Field name="latitude" component="input" />
