551685830/vue3-grid-layout-1

原仓库 https://github.com/jbaysolutions/vue-grid-layout一直没人重写 vue3 版本，所以我自己写了一个。 vue3 fork的仓库https://github.com/zhl1232/v3-grid-layout 在上面的两个仓库上，改为tsx 代码，修改了eventBus，暴露出 从外部拖曳到gird-layout 的变量

安装

npm install vue-grid-layout-next

使用

1. 全局注册
   在 main.ts 中引用

import { createApp } from 'vue'
import App from './App.vue'
import GridLayout from 'vue-grid-layout-next'
import 'vue-grid-layout-next/dist/style.css'
const app = createApp(App)
app.use(GridLayout).mount("#app")

2. 局部注册 jsx

import { defineComponent,ref } from 'vue'
import { GridItem, GridLayout, eventBusKey } from 'vue-grid-layout-next';
// import Bus from '@/utils/Bus';
export default defineComponent({
    name: 'App',
    setup() {
        // provide(eventBusKey, Bus); 需要外部调用方法时候使用
        const layout = ref([
            { x: 0, y: 0, w: 2, h: 2, i: '0', static: false, minH: 5 },
            { x: 2, y: 0, w: 2, h: 4, i: '1', static: true },
            { x: 4, y: 0, w: 2, h: 5, i: '2', static: false },
            { x: 6, y: 0, w: 2, h: 3, i: '3', static: false },
            { x: 8, y: 0, w: 2, h: 3, i: '4', static: false },
            { x: 10, y: 0, w: 2, h: 3, i: '5', static: false },
            { x: 0, y: 5, w: 2, h: 5, i: '6', static: false },
            { x: 2, y: 5, w: 2, h: 5, i: '7', static: false },
            { x: 4, y: 5, w: 2, h: 5, i: '8', static: false },
            { x: 6, y: 3, w: 2, h: 4, i: '9', static: true }
        ])
        return { layout }
    },
    render() {
        return (
            <GridLayout
                layout={this.layout}
                col-num={12}
                row-height={30}
                is-draggable={true}
                is-resizable={true}
                is-mirrored={false}
                vertical-compact={true}
                margin={[10, 10]}
                use-css-transforms={true}
            >
                {this.layout.map(item => (
                    <GridItem
                        key={item.i}
                        drag-allow-from='.toolbox'
                        i={item.i}
                        x={item.x}
                        y={item.y}
                        w={item.w}
                        h={item.h}
                        static={item.static}
                    >
                        <div class="box">
                            <div class="toolbox">drag</div>
                            <div class="item">
                                <div>{ item.i }</div>
                                <div>static:{ String(item.static) }</div>
                            </div>
                        </div>
                    </GridItem>
                ))}

            </GridLayout>
        )
    }
})

Bus 代码

import mitt from 'mitt';
import { ChartType } from '@/typings';
type Events = {
  menuDrag?: { e: DragEvent, chart: ChartType };
  menuDragend?: { e: DragEvent, chart: ChartType };
  dragEvent?: {
    eventType: string
    i: string | number
    x: number
    y: number
    h: any
    w: any
  },
  compact?: any
  setColNum?: any
};

const Bus = mitt<Events>();

export default Bus;

TODO

[x] 支持 TS
[x] vue3 setup 语法
[ ] BUG：vue2 版本高度计算 rowHeight 不只计算了 item 的高度，还把 margin 乘进去了，导致高度和栅格高度预期不符
[x] BUG：vue2 版本镜像反转后，拖拽会有限制
[ ] 文档优化
