gantt甘特图可拖拽、编辑(vue、react都可用 highcharts)
<p><span style="font-size: 14pt"><strong>前言</strong></span></p><p><span style="font-size: 14pt"><strong> </strong></span><span style="font-size: 16px">Excel功能强大,应用广泛。随着web应用的兴起和完善,用户的要求也越来越高。很多Excel的功能都搬到了sass里面。恨不得给他们做个Excel出来。。。程序员太难了。。。</span></p>
<p><span style="font-size: 16px"> 去年我遇到了一个甘特图的需求,做了很多工作,也写了两篇博客。一篇是用 GSTC 这个包做的甘特图,另一篇是自己手写了一个简易的甘特图。两个的效果都不理想,特别是GSTC,问题很多,好多道友看了博客遇到了问题,惭愧,没能帮大家解决这个问题。之前太忙了,这个甘特图就再没搞,直到今天发现了新的包,几乎是完全符合我们的需求。</span></p>
<p><span style="font-size: 16px"> 首先,我们用的是 highcharts;其次,大团队的产品,后期维护有保障,文档也齐全。</span></p>
<p><span style="font-size: 16px"> 我用 Vue3 写的,但是highcharts不区分他,是js包,所以无论 vue react 还是原生多页面都没问题。</span></p>
<p><span style="font-size: 16px"> 接下来先看一下我们的需求,也是最基本的,需要实现的功能,然后会有效果图的gif,最后就是源代码,我放在了Git上,觉得好用,麻烦给个star。</span></p>
<p> </p>
<p><span style="font-size: 14pt"><strong>需求</strong></span></p>
<p><span style="font-size: 16px">1、横轴左侧是表格数据,可以展示基本信息</span><br><span style="font-size: 16px">2、横轴右侧是时间轴,可以切换不同精度的时间展示</span><br><span style="font-size: 16px">3、横向数据块有多个,最好可以叠加</span><br><span style="font-size: 16px">4、数据块可以拖拽、点击等,修改任务的时间和其他信息</span></p>
<p> </p>
<p><span style="font-size: 14pt"><strong>效果图</strong></span></p>
<p> </p>

<p id="1637909989913"> </p>
<p> </p>
<p><span style="font-size: 16px"> 这个highcharts,不仅实现了左边表格,右边图标,而且数据是联动的;右边横轴是时间轴,可以自定义格式;数据允许叠加,不冲突;数据有点击等各种事件,可以选中编辑单个数据块;数据可以拖拽,比如上下换列拖拽、水平拖拽,还可以单边拖拽,而且事件都有回调函数。这些功能基本可以满足我们的需求。比如对时间段、时间长度、数据信息的修改和展示。</span></p>
<p> </p>
<p><strong><span style="font-size: 14pt">源码地址、代码解析</span></strong></p>
<p><span style="font-size: 16px"> </span><span style="font-size: 16px">先贴一下代码的Git地址,点击 GitHub源代码 下载源代码。建议直接下源码,跑项目,另外,这个项目是vue3的,不过对于这种包,写法差别不大,主要是参数。</span></p>
<p><span style="font-size: 16px"> 我贴一下代码,对功能实现做一个讲解,当然注释写的也是很详细的。</span></p>
<p> <span style="font-size: 16px">首先,highcharts-gantt.js 是专门用来实现甘特图的文件,draggable-points.js 是实现点事件绑定的文件。因为vue直接引入有找不到变量的报错,</span><span style="font-size: 16px">我将draggable-points的两个module直接添加到了highcharts-gantt里面,然后重新压缩,没有混淆,</span><span style="font-size: 16px">所以最终的包只有160K+,小了很多,大家可以直接用。压缩之后的源代码放心使用就行,我只是合并了2个文件的功能函数,但是也要格外提醒,不是官方的源文件了,感兴趣的同学可以去看官方源代码, .src 的文件是未压缩混淆的,注释也很详细。这是我合并文件时的版本 </span><span style="font-size: 16px">Highcharts Gantt JS v9.3.1 (2021-11-05),这个也是当前的稳定版本。</span></p>
<p> </p>
<p><span style="font-size: 16px"> 功能有点简单,好像代码没什么好说的。关键的地方我都做了注释,还有不明白的可以留言或者评论。</span></p>
<p><span style="font-size: 16px"> 最后,还存在一个问题,我没仔细研究源码,这个示例还存在一个问题,就是拖拽事件没有中断,而且直接修改了图表的数据展示。比如,纵向拖动换行时,左侧表格的数据会变化。暂时我还没有找到满意解决的方法。目前,我在拖拽结束的回调 drop 函数中,对数据做了处理,然后将我们希望的数据回写,更新图表,同样你也可以做 不能拖拽或者时间冲突等各种校验,达到上面我所说的需求。但是还有一点瑕疵,就是拖拽过程中的数据变化,左侧表格的数据拖拽过程中我也不希望他变化,暂时没能解决掉。如果您有好的案例、好的使用、好的建议,都希望可以提出来,共同进步。</span></p>
