我正在使用React本机的应用程序中工作,这里是我遇到麻烦的代码:
import React, {Component} from 'react';
import {Text, StyleSheet} from 'react-native';
import { Content, Card, CardItem, Body, Left} from 'native-base';
import { PricingCard } from 'react-native-elements'
export default class AppBodyData extends Component {
render() {
let articles = this.props.data.map(function (articleData, index) {
return (
<PricingCard
//color='#ff3300'
wrapperStyle={(articleData.percent_change_1h >= 0) ? styles.green : styles.red}
info={["1h change: "+ articleData.percent_change_1h, "24h change: "+ articleData.percent_change_24h, "7days change: "+ articleData.percent_change_7d]}
button={{ title: 'More information', icon: 'info', backgroundColor: '#4f9deb' }}
/>
)
});
return (
<Content>
{articles}
</Content>
);
}
}
const styles = StyleSheet.create({
green: {
color: '#00ff00'
},
red: {
color: '#ff0000'
}
});
module.export = AppBodyData;
我需要的是,如果articleData.percent_change_1h
变量为正,则该变量的颜色必须为绿色,否则必须为红色。
PricingCard是react-native-elements库的对象:https://react-native-training.github.io/react-native-elements/API/pricing/
