我试图用终极版,形式相同的值反应的小部件多选this example:终极版形式始终返回多选反应的微件
var Multiselect = ReactWidgets.Multiselect
, people = listOfPeople();
var Example = React.createClass({
getInitialState() {
return { value: people.slice(0,2) };
},
_create(name){
var tag = { name, id: people.length + 1 }
var value = this.state.value.concat(tag)
// add new tag to the data list
people.push(tag)
//add new tag to the list of values
this.setState({ value })
},
render(){
// create a tag object
return (
<Multiselect data={people}
value={this.state.value}
textField="name"
onCreate={this._create}
onChange={value => this.setState({ value })}/>
)
}
});
ReactDOM.render(<Example/>, mountNode);
下面是一个父组件的代码片断这使得使用终极版形式(EditVideo
组件)组件(请看看的onsubmit方法的注释):
class VideoEdit extends React.Component {
constructor(props) {
super(props);
}
onSubmit = (values) => {
console.log(values.categories) // always returns initialValues for categories, new values not adding
}
render() {
const { loading, videoEdit, categories } = this.props;
if (loading) {
return (
<div>{ /* loading... */}</div>
);
} else {
return (
<div>
<h2>Edit: {videoEdit.title}</h2>
<EditVideo
onSubmit={this.onSubmit}
initialValues={videoEdit}
categories={categories}
/>
</div>
);
}
}
}
这里是终极版形成分与反应的微件多选组件的代码片段:
class CategoryWidget extends React.Component {
constructor(props) {
super(props);
this.state = {
value: this.props.defValue,
extData: this.props.data
}
this._create = this._create.bind(this);
}
_create(name) {
var tag = { name, id: this.state.extData.length + 100 + 1 }
var value = this.state.value.concat(tag)
var extData = this.state.extData.concat(tag)
this.setState({
extData,
value
})
}
render() {
return (
<Multiselect
{...this.props.input}
data={this.state.extData}
onBlur={() => this.props.input.onBlur()}
value={this.state.value || []}
valueField="id"
textField="name"
onCreate={this._create}
onChange={value => this.setState({ value })}
/>
)
}
}
const EditVideoForm = (props) => {
const { handleSubmit, submitting, onSubmit, categories, initialValues, defBook } = props;
return (
<Form name="ytvideo" onSubmit={handleSubmit(onSubmit)}>
<div>
<Field
name="categories"
component={CategoryWidget}
data={categories}
defValue={initialValues.categories}
/>
</div>
<br />
<Button color="primary" type="submit" disabled={submitting}>
Submit
</Button>
</Form>
);
};
export default reduxForm({
form: 'videoEdit',
enableReinitialize: true
})(EditVideoForm);
Multiselect
小部件按预期工作,但提交表单始终返回类别的相同初始值。
我认为这个问题存在的事实是CategoryWidget
是一个类的基础组件?如果是这样,那么使它工作的方法是什么?
