鉴于父组件,我使用的子组件DynamicFieldSet
是FormItems
的分组。但我收到错误:
Warning: validateDOMNesting(...): <form> cannot appear as a descendant of <form>. See CreateTopic > Form > form > ... > DynamicFieldSet > Form > form.
我尝试删除子组件中的<Form> </Form>
标记,但这是编译错误。
有没有办法可以禁用子窗体视图的渲染?
父组件
class CreateTopic extends React.Component {
render() {
return (
<div className="create-topic-container">
<h3>Create an event</h3>
<Form onSubmit={this.handleSubmit}>
<FormItem>...</FormItem>
<FormItem>...</FormItem>
<FormItem>...</FormItem>
<FormItem
{...formItemLayout}
label="Results"
style={{ marginBottom: SPACING_FORM_ITEM }}
>
{getFieldDecorator('results', {
rules: [
{
required: true,
message: 'Results cannot be empty.',
},
],
})(<DynamicFieldSet
form={this.props.form}
/>)}
</FormItem>
</Form>
</div>
);
}
}
DynamicFieldSet - 子组件
export class DynamicFieldSet extends React.Component {
render() {
getFieldDecorator('keys', { initialValue: ['0', '1'] });
const keys = getFieldValue('keys');
const formItems = keys.map((k, index) => {
return (
<FormItem
{...formItemLayoutWithOutLabel}
required={false}
key={k}
>
{getFieldDecorator(`results[${k}]`, {
validateTrigger: ['onChange', 'onBlur'],
rules: [
{
required: true,
whitespace: true,
message: 'Result name cannot be empty.',
},
{
validator: this.validateLength,
},
],
})(<Input placeholder={`Result #${index + 1}`} style={{ width: '80%', marginRight: 8 }} />)}
{keys.length > 2 ? (
<Icon
className="dynamic-delete-button"
type="minus-circle-o"
disabled={keys.length === 1}
onClick={() => this.remove(k)}
/>
) : null}
</FormItem>
);
});
return (
<Form>
{formItems}
<FormItem {...formItemLayoutWithOutLabel}>
{keys.length < 10 ? (
<Button type="dashed" onClick={this.add} style={{ width: '80%' }}>
<Icon type="plus" />Add Result
</Button>
) : null}
</FormItem>
</Form>
);
}
}

我在使用ant design table
时遇到了这个问题,并发现它的非蚂蚁设计引发了警告。这是网络标准description
"Every form must be enclosed within a FORM element. There can be several forms in a single document, but the FORM element can't be nested."
因此,表单标签内不应有表单标签。
要解决此问题(在我们的示例中),请删除DynamicFieldSet“返回”中的Form
标签,并替换为div
标签
希望它会有所帮助:)

这是由于您在另一个<form>
标记内声明了<form>
而引起的。
