我正在使用semantic-ui-react的Form.Input,它将输入包装在两个div中。
这意味着,
<Form.Input type='password' name='password' id='loginPassword'></Form.Input>
呈现如下:
<div class='field'>
<div class='ui fluid action left icon input'>
<input type='password' name='password' id='loginPassword' ...>
<button ...>
</div>
</div>
我想获取<input/>
元素的引用,以便我可以调用focus()。
如何获取<input/>
元素的参考号?

Form.Input
的某些组件, Input
只是shorthand。
所以在幕后这个:
<Form.Input label='Enter Password' type='password' />
与此相同:
<Form.Field>
<label>Enter Password</label>
<Input type='password' />
</Form.Field>
semantic-ui-react
的{p> Input
supports the react ref
API,但要确保您使用的是current ref
API,而不是the old one:
<Input ref={ref => this.input = ref} />
运行示例:
const { Input, Button } = semanticUIReact; // import
class App extends React.Component {
onClick = () => this.input.focus();
render() {
return (
<div>
<Input ref={ref => this.input = ref} />
<Button onClick={this.onClick}>Focus</Button>
</div>
);
}
}
ReactDOM.render(<App />, document.getElementById('root'));

当你使用findDOMnode(通常不建议)时,你会回到标准的js中,所以这个:
public class MinimalMigrationLogger : MigrationsLogger
{
public override void Info(string message)
{
// Ignore it; there's too much of it clogging up CI
}
public override void Verbose(string message)
{
// The SQL text and other info comes here
// Ignore it; there's too much of it clogging up CI
}
public override void Warning(string message)
{
Console.WriteLine(message);
}
}
应该有效
