一、需求

        在工作中遇到一个需求，做一个类似于调试工具栏的效果，点击某个按钮呼出，并且组件可以很便捷的实现可拖拽改变组件大小。

二、插件的安装使用

插件安装：

npm install --save re-resizable

插件引入：

import { Resizable } from "re-resizable";

基本使用：

import React, {Component} from 'react';
import { Resizable } from "re-resizable";

export default class demo extends Component {
    render() {
        return (
            <Resizable
                defaultSize={
   
   {width:400, height:400}}
            >
                你好，大聪明！
            </Resizable>
        );
    }
}

常用属性：

更多使用方法详见官网。

三、事件

• onResizeStart 调整组件开始时调用。

• onResize 调整组件进行时调用。

• onResizeStop 调整组件完成时调用。

代码：

import React, {Component} from 'react';
import { Resizable } from "re-resizable";

export default class Demo extends Component {

    onResizeStart = (e) => {
        console.log("onResizeStart执行");
        console.log(e);
    };
    onResize = (e) => {
        console.log("onResize执行");
        console.log(e);
    };
    onResizeStop = (e) => {
        console.log("onResizeStop执行");
        console.log(e);
    };

    render() {
        return (
            <Resizable
                style={
   
   {background: "red"}}
                defaultSize={
   
   {width:400, height:400}}
                onResize={(e) => this.onResize(e)}
                onResizeStart={(e) => this.onResizeStart(e)}
                onResizeStop={(e) => this.onResizeStop(e)}
            >
                你好，大聪明！
            </Resizable>
        );
    }
}
