我想制作带有标签的div并勾勒出轮廓,并找到了this的答案,这正是我所需要的。但是,当我尝试在OutlinedDiv
内使用某些输入时会出现问题。键入任何字符后,它将失去焦点。我发现问题是OutlinedDiv
中使用的箭头功能:
inputComponent: ({ className }) => (
<div key="divKey" className={className}>{children}</div>)
,如果我使用简单的div
而不是OutlinedDiv
,则一切正常。因此,我可以用可以与输入配合使用的方式重写OutlinedDiv
吗?我什至没有感觉我在这里有什么选择。
index.js
import React from "react";
import ReactDOM from "react-dom";
import OutlinedDiv from "./OutlinedDiv";
import TextField from "@material-ui/core/TextField";
function App() {
const [state, setState] = React.useState({ inputValue: "", inputValue2: "" });
function handleChange(event) {
setState({ ...state, [event.target.name]: event.target.value });
}
return (
<div className="App">
<OutlinedDiv key="outlinedDivKey" label="OutlinedDivTest">
<div>
<TextField
id="inputValue"
key="inputValueKey"
name="inputValue"
label="Some input"
inputProps={{ style: { textAlign: "right" } }}
value={state.inputValue}
onChange={event => handleChange(event)}
/>
</div>
<div>
<TextField
id="inputValue2"
key="inputValueKey2"
name="inputValue2"
label="Some input2"
inputProps={{ style: { textAlign: "right" } }}
value={state.inputValue2}
onChange={event => handleChange(event)}
/>
</div>
</OutlinedDiv>
</div>
);
}
const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);
outlinedDiv.js
import React from "react";
import TextField from "@material-ui/core/TextField";
const OutlinedDiv = ({ children, label }) => {
return (
<TextField
variant="outlined"
label={label}
multiline
InputLabelProps={{ shrink: true }}
InputProps={{
inputComponent: ({ className }) => (
<div key="divKey" className={className}>
{children}
</div>
)
}}
/>
);
};
export default OutlinedDiv;
答案 0 :(得分:1)
我已经更新了之前的答案,将以下内容用于OutlinedDiv
实现:
import React from "react";
import TextField from "@material-ui/core/TextField";
const InputComponent = ({ inputRef, ...other }) => <div {...other} />;
const OutlinedDiv = ({ children, label }) => {
return (
<TextField
variant="outlined"
label={label}
multiline
InputLabelProps={{ shrink: true }}
InputProps={{
inputComponent: InputComponent
}}
inputProps={{ children: children }}
/>
);
};
export default OutlinedDiv;
这样可以避免在重新渲染时重新安装输入组件。
这是您的沙盒的修改版本:
