文章介绍了如何使用Vue和elementUI Plus实现一个简单的拖拽流程图功能,不引入任何插件,完全手写,设计思路,感兴趣的朋友跟随小编一起看看吧

vue elementUI Plus实现拖拽流程图,不引入插件,纯手写实现。

1.设计思路:

左侧button列表是要拖拽的组件。中间是拖拽后的流程图。右侧是拖拽后的数据列表。

我们拖动左侧组件放入中间的流程图中,并把button携带的数据信息带过来。

2.设计细节

左侧button组件列表可拖动并携带信息,当拖动到中间流程图上方时,流程图网格变色。当鼠标释放后,数据传递,流程图变化。

拖拽事件流程和参数
‌dragstart‌:当元素开始被拖拽时触发。
‌drag‌:元素正在被拖拽时持续触发(某些浏览器支持)。
‌dragend‌:当拖拽结束时触发。
‌dragenter‌:当拖拽的元素进入目标元素时触发。
‌dragover‌:当拖拽的元素在目标元素上移动时持续触发。
‌dragleave‌:当拖拽的元素离开目标元素时触发。
‌drop‌:当拖拽的元素在目标元素上释放时触发。

3.详细代码实现
