【中文标题】TypeError: undefined is not a function (in \'...styled Components.default.button...\')【英文标题】:TypeError: undefined is not a function (near '..._styledComponents.default.button...')TypeError: undefined is not a function (in '...styled Components.default.button...') 【发布时间】:2021-11-12 00:49:01 【问题描述】:我在 react native 项目中使用 styled-components
时遇到此错误。
TypeError: undefined is not a function (near '..._styledComponents.default.button...')
这是我的代码;
import styled from "styled-components";
const Buttonn = styled.button`
background: white;
width: 200px;
height: 50px;
bordercolor: black;
font-size: 24px;
color: black;
text-align: center;
&:hover
background: black;
color: white;
`;
function CourierDetails()
return (
<Buttonn>Submit</Buttonn>
)
【问题讨论】:
【参考方案1】:styled.button 在 React (web) 中工作,如果你想在 React-native 中设置一个 Button 的样式,你必须使用 react-native 提供的 Button 组件。
您还必须从 'styled-components/native' 导入样式化组件
import styled from 'styled-components/native'
你可以像下面这样创建一个CustomButton组件
import React from 'react';
import styled from 'styled-components/native';
const CustomButton = props => (
<ButtonContainer
onPress=() => alert('Hi!')
backgroundColor=props.backgroundColor
>
<ButtonText textColor=props.textColor>props.text</ButtonText>
</ButtonContainer>
);
export default CustomButton;
const ButtonContainer = styled.TouchableOpacity`
width: 100px;
height: 40px
padding: 12px;
border-radius: 10px;
background-color: $props => props.backgroundColor;
`;
const ButtonText = styled.Text`
font-size: 15px;
color: $props => props.textColor;
text-align: center;
`;
希望这个回答对你有帮助,谢谢!
