• 通过单击编辑图标实现页面中对应按钮的呈现与隐藏、

• 效果图如下

2、代码实现

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;

• display属性可以控制内容的呈现与隐藏，none表示隐藏，block表示呈现
• 第一步：利用状态机设置display_name
• 第二步：控件按钮放在div中进行呈现，div内容的呈现与否通过display实现，display具体取值取状态机中的display_name
• 第三步：给编辑图标添加单击事件：修改状态机display_name的取值，状态机一旦改变页面便会立即加载，即控制按钮的呈现与隐藏
