如何使用 Modal 只获得一个值
How to get only ONE value using Modal
我正在使用 Modal,但出现问题,使用 Modal 我从 About
获得了所有 name
,但没有我只得到一个值。我只需要使用 Modal
取一个值
import React, { Component } from "react";
import { Text, View } from "react-native";
import Modal from "react-native-modal";
export default class App extends Component {
state = {
visible: false
};
renderMap() {
const About = [
{
name: "Gabe",
msg: "Hello",
img: "Some Img"
},
{
name: "Amanda",
msg: "Hi",
img: "Another img"
},
{
name: "Cauã",
msg: "Whats up ",
img: "Another img"
}
];
const Choose = About.map((info) => {
return (
<View style={{ width: 180, backgroundColor: "red", marginTop: 10 }}>
<Text
onPress={() => {
// console.log(info.name);
// delete the MODAL and try out this only with the console.log
this.setState({
visible: true
});
}}
>
Click on the Title
</Text>
<Modal isVisible={this.state.visible}>{console.log(info.name)}</Modal>
</View>
);
});
return Choose;
}
render() {
return <View>{this.renderMap()}</View>;
}
}

你看到了吗?没有 Modal,我在 console.log() 上得到了准确的值,但是有了 Modal,我得到了三个值。我需要一些使用 Modal
获得价值的东西
好办法
import React, { Component } from "react";
import { Text, View } from "react-native";
import Modal from "react-native-modal";
export default class App extends Component {
state = {
visible: false,
userInfos: null
};
renderMap() {
const About = [
{
name: "Gabe",
msg: "Hello",
img: "Some Img"
},
{
name: "Amanda",
msg: "Hi",
img: "Another img"
},
{
name: "Cauã",
msg: "Whats up ",
img: "Another img"
}
];
const Choose = About.map((info) => {
return (
<View style={{ width: 180, backgroundColor: "red", marginTop: 10 }}>
<Text
onPress={() => {
this.setState({
visible: true,
userInfos: info
});
}}
>
Click on the Title
</Text>
</View>
);
});
return Choose;
}
render() {
return(
<View>
{this.renderMap()}
<Modal isVisible={this.state.visible}>
<Text>{this.state.userInfos.name}</Text>
</Modal>
</View>
)
}
}
