问题
When using ordinary CSS if you want to style your place holder you use these css selectors :
::-webkit-input-placeholder {
color: red;
}
But I can't figure out how to apply these type of styles in react inline styles.
回答1:
You could try to use radium
var Radium = require('radium');
var React = require('react');
var color = require('color');
@Radium
class Button extends React.Component {
static propTypes = {
kind: React.PropTypes.oneOf(['primary', 'warning']).isRequired
};
render() {
// Radium extends the style attribute to accept an array. It will merge
// the styles in order. We use this feature here to apply the primary
// or warning styles depending on the value of the `kind` prop. Since its
// all just JavaScript, you can use whatever logic you want to decide which
// styles are applied (props, state, context, etc).
return (
<button
style={[
styles.base,
styles[this.props.kind]
]}>
{this.props.children}
</button>
);
}
}
// You can create your style objects dynamically or share them for
// every instance of the component.
var styles = {
base: {
color: '#fff',
// Adding interactive state couldn't be easier! Add a special key to your
// style object (:hover, :focus, :active, or @media) with the additional rules.
':hover': {
background: color('#0074d9').lighten(0.2).hexString()
},
'::-webkit-input-placeholder' {
color: red;
}
},
primary: {
background: '#0074D9'
},
warning: {
background: '#FF4136'
}
};

You can't use ::-webkit-inline-placeholder
inline.
It is a pseudo-element that (much like e.g. :hover
) can only be used in your stylesheet:
The non-standard proprietary
::-webkit-input-placeholder
pseudo-element represents the placeholder text of a form element.

Instead, assign a class to the React component via the className
property and apply the style to this class.

Do not use ::-webkit-inline-placeholder inline and Radium for one placeholder.
I suggest go to your index.css
input.yourclassname::placeholder { /* Chrome, Firefox, Opera, Safari 10.1+ */
color: white;
opacity: 1; /* Firefox */
}

For me, I use Radium's Style component. Here's what you can do in ES6 syntax:
import React, { Component } from 'react'
import Radium, { Style } from 'radium'
class Form extends Component {
render() {
return (<div>
<Style scopeSelector='.myClass' rules={{
'::-webkit-input-placeholder': {
color: '#929498'
}}} />
<input className='myClass' type='text' placeholder='type here' />
</div>
}
}
export default Radium(Form)

Simply give your "input" tag an "id" or a "class" and put your css style in App.css inside src. e.g
//App.css or external stylesheet
#inputID::placeholder {
color: #ff0000;
opacity: 1;
}
//your jsx code
<input type="text" id="inputID" placeholder="Your text here" />
That actually worked for me.
