javascript - 更新 : AndroidTextInput 管理的 View 的属性 'placeholder' 时出错

Question

我正在尝试访问 native 基础 Item 组件内部的 prop，它会抛出

    Error while updating property 'placeholder' of a view managed
    by:AndroidTextInput

    TypeError: expected dynamic type `string', but had type `int64'

这是返回此错误的代码

import React, { Component } from 'react';
import { Container, Content, Form, Item, Input, Button, Text } from 'native-base';

export default class EditProduct extends Component {
  componentDidMount() {
    Actions.refresh({
     title: 'Edit Product',
     leftTitle: '<',
     onLeft: () => {},
   });
}

render() {
  const id = this.props.id || 'No ID';
  const min = this.props.min || 'No Min';
  const max = this.props.max || 'No Max';

  return (
    <Container>
     <Content>
      <Form>
        <Item>
          <Input placeholder=id />
        </Item>
        <Item>
          <Input placeholder=max />
        </Item>
        <Item last>
          <Input placeholder=min />
        </Item>

        <Button block>
          <Text>Confirm</Text>
        </Button>
      </Form>
     </Content>
   </Container>
 );
 }
}

如何将 int64 转换为字符串？除了转换之外还有其他选择吗？

Answer 1

输入的 props 占位符接收字符串，只需将其转换为字符串即可。

const id = this.props.id + ""
