blocks|key|226095|text|按照我的建议，使用第三方库来集成到Textfield组件中；您可以使用react-number-format库作为Textfield的inputProp。它之所以有效，是因为上面提到的库提供的数字格式化程序有一个缺省为一个字符串"."的decimalSeparator属性|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|226096|自定义数字格式化程序如下所示：|226097|import+NumberFormat+from+'react-number-format';

++);
}|code-block|syntax|javascript|226098|它可以用在数字文本字段中，如下所示：|226099|<TextField

As per my suggestion of using a third-party library to be integrated in the Textfield component; You could use the <a href="https://www.npmjs.com/package/react-number-format" rel="nofollow noreferrer">react-number-format</a> library as an inputProp for the Textfield. It works because the number formatter offered by the aforementioned library has a <code>decimalSeparator</code> prop which defaults to the one character string <code>"."</code>

The custom number formatter would go like this:

<pre><code>import NumberFormat from 'react-number-format';

interface NumberFormatCustomProps {
 inputRef: (instance: NumberFormat | null) =&gt; void;
 onChange: (event: { target: { value: string } }) =&gt; void;
}

function NumberFormatCustom(props: NumberFormatCustomProps) {
 const { inputRef, onChange, ...other } = props;

 return (
 &lt;NumberFormat
 {...other}
 getInputRef={inputRef}
 onValueChange={values =&gt; {
 onChange({
 target: {
 value: values.value
 }
 });
 }}
 isNumericString
 /&gt;
 );
}
</code></pre>

And it could be used in a number Textfield like this: 

<pre><code>&lt;TextField
 label="react-number-format"
 value={values.numberformat}
 onChange={handleChange("numberformat")}
 id="formatted-numberformat-input"
 InputProps={{
 inputComponent: NumberFormatCustom as any
 }}
 type="number"
/&gt;
</code></pre>

blocks|key|2294599|text|对我来说，在inputProps中将language属性设置为"en-US"是可行的：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2294600|<TextField
++++type="number"
++++inputProps={{step:+"0.1",+lang:"en-US"}}

For me, setting the language attribute to <code>&quot;en-US&quot;</code> in the <code>inputProps</code> worked:
<pre><code>&lt;TextField
 type=&quot;number&quot;
 inputProps={{step: &quot;0.1&quot;, lang:&quot;en-US&quot;}}
 /&gt;
</code></pre>

blocks|key|226103|text|我提出了一个同时接受和的解决方案。分隔符使用正则表达式验证器。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|226104|除了控制输入标签之外，我还控制外部数字状态。|226105|在我的解决方案中，用户只能输入分隔的小数。或者，只有当用户输入可转换为浮点型时，输入标签和数字状态才会改变，如果输入为空"“，则数字状态设置为null。|226106|++++const+[inputValue,+setInputValue]+=+useState<string>("")

I came out with solution that accepts both , and . separators using regex validator.
In addition of controlling input label, I control external numeric state &lt;number | null&gt;.
In my solution user can only input decimals separated . or , The input label and numeric state only changes if user input is convertable to float, In case of empty &quot;&quot; input, numeric state is set to null.
<pre><code> const [inputValue, setInputValue] = useState&lt;string&gt;(&quot;&quot;)
 const [numericValue, setNumericValue] = useState&lt;number | null&gt;(null)

 return (&lt;TextField
 inputMode={&quot;numeric&quot;}
 onChange={(e) =&gt; {
 e.preventDefault();
 // if new value is valid float
 if (/^([\d]*[,.]?[\d]{0,2})$/.test(e.target.value)) {
 setInputValue(e.target.value);
 const parsed = parseFloat(
 e.target.value.replaceAll(&quot;,&quot;, &quot;.&quot;)
 );
 setNumericValue(isNaN(parsed) ? null : parsed)
 }
 }}
 value={inputValue}
 /&gt;);
</code></pre>

I am using <code>material-ui</code> to render a <code>TextField</code> component in my <code>react</code> app. It's somehow forcing all the <code>&lt;TextField type="number /&gt;</code> to have decimal separator as comma (,) instead of dot (.) which is confusing for the targeted users. 

Is there any way to force it to always show dot as the decimal separator, regardless of locale? 

I have created a <a href="https://codesandbox.io/s/material-demo-hsj2l" rel="noreferrer">small example here</a>. just try to enter a number with decimals and click outside and it'll convert it into comma. This is probably because of my current device locale, but still I want to force a dot for everyone.
