import React, { Component } from 'react';
import '../../../style_css/antd.css';
import { Layout,Icon,Row, Col} from 'antd';
class Index extends Component {
    // 状态机
    constructor(props, context) {
        super(props, context);
        this.state = {
            display_name: 'none', //此状态机为display的取值
        }
    }
    display_name() { //编辑按钮的单击事件，修改状态机display_name的取值
        if (this.state.display_name == 'none') {
            this.setState({
                display_name: 'block',
            })
        }
        else if (this.state.display_name == 'block') {
            this.setState({
                display_name: 'none',
            })

        }
    }
    render() {
        return (
            <layout>
                {/* 一行：按钮 */}
                <div>    {/* 通过状态机display_name获取diaplay取值 */}
                    <row>
                        <col>
                        
                        <col>
                            <div>
                                <span><button>详情</button> </span>
                                <span><button>添加</button></span>
                                <span><button>修改</button></span>
                                <span><button>删除</button></span>
                                <span><button>查看关联</button></span>
                            </div>
                        
                    </row>
                </div>
                {/* 通过icon实现编辑图标 */}
                <div>
                    <row>
                        <col>
                        
                        <col> {/* 通过display_name函数来改变状态机display_name的值来改变display取值 */}
                            <icon></icon>
                        
                    </row>
                </div>
                {/* 页面内容 */}
                <layout>
                    <content>
                        {this.props.children}
                    </content>
                </layout>
            </layout>
        );
    }
}
export default Index;

The display attribute can control the presentation and hiding of content, none means hiding, block means presenting
• Step 1: Use the state machine to set display_name
• Step 2: Place the control button in a div for presentation. Whether the div content is presented or not is implemented through display. The specific value of display is the display_name in the state machine
• Step 3: Add a click event to the edit icon: modify the value of the state machine display_name. Once the state machine changes, the page will be loaded immediately, that is, the presentation and hiding of the control button
