我正在使用React native的应用程序中工作,下面是我遇到问题的代码:
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
该变量的颜色
必须为绿色,否则必须为红色。
PricingCard是react native elements library的对象:
