如何样式材质-UI 文本字段

Try using the inputStyle prop on TextField. From the docs...

inputStyle (object) - Override the inline-styles of the TextField's input element. When multiLine is false: define the style of the input element. When multiLine is true: define the style of the container of the textarea.

<TextField inputStyle=\{\{ backgroundColor: 'red' }} />

You need to add the InputProps property to the TextField.

const styles = theme => ({
textField: {
width: '90%',
marginLeft: 'auto',
marginRight: 'auto',
paddingBottom: 0,
marginTop: 0,
fontWeight: 500
},
input: {
color: 'white'
}
});

JSX:

<TextField
id="email"
label="Email"
className={classes.textField}
value={this.state.form_email}
onChange={this.handle_change('form_email')}
margin="normal"
InputProps=\{\{
className: classes.input,
}}
/>

As an aside, you can also style the label or use an override as described here.

It really depends on what exactly are you trying to change.

The documentation has a bunch of examples on custom TextFields, take a look at them here:

https://material-ui.com/demos/text-fields/#customized-inputs

More information about customization can be found here:

https://material-ui.com/customization/overrides/

and

https://material-ui.com/customization/themes/

Have you tried using !important for the color changes? I had the same problem when I tried to set a default color for the border of an outlined TextField

Take a look at this: https://stackblitz.com/edit/material-ui-custom-outline-color

This is a solution with inline styles:

<TextField
style=\{\{
backgroundColor: "blue"
}}
InputProps=\{\{
style: {
color: "red"
}
}}
/>

I'd suggest keeping your style within a theme.

const theme = createMuiTheme({
overrides: {
MuiInputBase: {
input: {
background: "#fff",
},
},
},
});

All the answers here shows how to style things with InputProps or inputProps, but no one explained why, and how it works. And no one explained whats the difference between inputProps and InputProps

<TextField
variant="outlined"
// inputProps are used to pass attributes native to the underlying
// HTML input element, e.g. name, id, style.
inputProps=\{\{
style: { textAlign: 'center' },
}


// InputProps (capital I) passes props to the wrapper Material
// component. Can be  one of the following: Input, FilledInput,
// OutlinedInput. You can pass here anything that the underlying
// Material component uses: error, value, onChange, and classes.
InputProps=\{\{
// Usually you don't need className, the `classes` object will
// be sufficient. However, you can also use it and this will
// add your class to the div of the InputBase.
className: styles.slider_filter_input,
classes: {
root: classes.root
focused: classes.focused
// The list of keys you pass here depend on your variant
// If for example you used variant="outlined", then you need
// to check the CSS API of the OutlinedInput.
}
}}
/>

Here is a working codesandbox showing the ideas above.

Try using the FilledInput component instead of TextField. Then you can use simple inline styling like this:

style=\{\{color: 'white' }}

This also will lighten the placeholder text... hooray.

You cann pass styles to any of the children elements in the hierarchy:

TextField > Input > input (HTML element)

Notice the uper or lower case in InputProps vs. inputProps

// pass styles (or props) to the Input component
<TextField InputProps=\{\{className: classes.input}} />


// pass styles (or props) to the inner input element
<TextField inputProps=\{\{className: classes.input}} />

As of MUI V5, you can use the sx prop to change style settings. You still need to use inputProps to pass down those props to the input field. You could consider doing it like this:

              <TextField
sx=\{\{ marginTop: 10 }}
inputProps=\{\{ sx: {color: '#fff'} }}
/>

The SX prop in MUI V5

<TextField
color="whitish"
label="Enter Your Name"
type="Text"
InputLabelProps=\{\{
style: { color: "white" },
}}
sx=\{\{
".css-x2l1vy-MuiInputBase-root-MuiOutlinedInput-root": {
color: "white",
},
}}
InputProps=\{\{
sx: {
".css-1d3z3hw-MuiOutlinedInput-notchedOutline": {
border: "2px solid white",
},
"&:hover": {
".css-1d3z3hw-MuiOutlinedInput-notchedOutline": {
border: "2px solid white",
},
},
},
}}
size="medium"
variant="outlined"
fullWidth
value={name}
onChange={(e) => {
setName(e.target.value);
}}
/>
