在线电子表格编辑器 Luckysheet

 

下载地址

不知道地址正不正经,我先用着,网上找的地址,不知道是不是可信任的,疑似官网的两个地址都打不开,

https://github.com/dream-num/Luckysheet

 

zip包  https://codeload.github.com/dream-num/Luckysheet/zip/refs/heads/master

或者克隆 

别人是这里下载的,好像是官网之一,打不开

 这里有学习文档 :https://mengshukeji.gitee.io/LuckysheetDocs/zh/guide/#%E5%9F%BA%E6%9C%AC%E4%BB%8B%E7%BB%8D

 

引用方法

在提交PR之前,请确保仔细阅读 贡献指南

用法

第一步

通过CDN引入依赖

<link rel='stylesheet' href='https://cdn.jsdelivr.net/npm/luckysheet@latest/dist/plugins/css/pluginsCss.css' />
<link rel='stylesheet' href='https://cdn.jsdelivr.net/npm/luckysheet@latest/dist/plugins/plugins.css' />
<link rel='stylesheet' href='https://cdn.jsdelivr.net/npm/luckysheet@latest/dist/css/luckysheet.css' />
<link rel='stylesheet' href='https://cdn.jsdelivr.net/npm/luckysheet@latest/dist/assets/iconfont/iconfont.css' />
<script src="https://cdn.jsdelivr.net/npm/luckysheet@latest/dist/plugins/js/plugin.js"></script>
<script src="https://cdn.jsdelivr.net/npm/luckysheet@latest/dist/luckysheet.umd.js"></script>

第二步

指定一个表格容器

<div id="luckysheet" style="margin:0px;padding:0px;position:absolute;width:100%;height:100%;left: 0px;top: 0px;"></div>

第三步

创建一个表格

<script>
    $(function () {
        //配置项
        var options = {
            container: 'luckysheet' //luckysheet为容器id
        }
        luckysheet.create(options)
    })
</script>

引用效果

如果不添加其它的,它是整个浏览器全屏显示

 

 我找了是把它放在其它div下,非全屏,必须得加高度,不然显示不出来单元格

 

 

 body下没设置其它div,是这样的全屏效果

 离线部署获得dist文件

yum install npm

# 拉取代码,我是下载的zip包安装的,这个地址不知道是不是官网的,好像不是
git clone https://github.com/mengshukeji/Luckysheet.git

# 安装
cd Luckysheet-master npm install npm install gulp -g # 运行 npm run build

[root@mcw01 Luckysheet-master]# ls
CHANGELOG.md  commitlint.config.js  deploy.bat  dist  docs  gulpfile.js  LICENSE  node_modules  package.json  package-lock.json  README.md  README-zh.md  src  yarn.lock
[root@mcw01 Luckysheet-master]# ls dist/
assets  css  demoData  expendPlugins  fonts  index.html  luckysheet.umd.js  luckysheet.umd.js.map  plugins
[root@mcw01 Luckysheet-master]# tar zcf mytable.tar.gz dist
[root@mcw01 Luckysheet-master]# ls
CHANGELOG.md  commitlint.config.js  deploy.bat  dist  docs  gulpfile.js  LICENSE  mytable.tar.gz  node_modules  package.json  package-lock.json  README.md  README-zh.md  src  yarn.lock
[root@mcw01 Luckysheet-master]# 

把生成的dist放到代码下面,我这里只是单纯的随便放的,然后把你网页的静态文件地址改成当前文件dist下的静态文件

 

 没问题,正常使用,是用的本地文件。不是请求的网上的文件了

 

 引用方法同上

            data:{"sheetData":celldata,"scheId":0},
            Type:"post",
            dataType:"json",
            success:function(res) {
                console.log(res);
            }
        });
    }

视图函数

@article_bp1.route('/testmytb', methods=['POST', 'GET'])
def testmytb():
        return render_template('test.html')


@article_bp1.route('/mcw', methods=['POST', 'GET'])
def testmytb1():
    print(request.args)
    return ''

从数据库中获取数据并渲染在表格中

 <div id="luckysheet" style="margin-top:48px;padding:0px;position:absolute;width:100%;height:90%;left: 0px;top: 0px;">
    </div>


$(function () {
        var options = {
            container: 'luckysheet',
            title: '工作汇报',
            lang: 'zh',
            showsheetbar:false,
            data: [
                {
                    "name": "进度填报表",
                    "status": 1,
                     "celldata": [{"r":0,"c":0,"v":{"m":"dd","ct":{"fa":"General","t":"g"},"v":"dd"}},{"r":0,"c":1,"v":{"m":"dd","ct":{"fa":"General","t":"g"},"v":"dd"}},{"r":0,"c":2,"v":{"m":"b","ct":{"fa":"General","t":"g"},"v":"b"}}]
                }
            ]
        }
        luckysheet.create(options);
    })

    }

单元格数据结构如下:

分析:

  • title: '工作汇报',可以指的工作簿名称;
  • 我们指定了表名但是没有出来  "name": "进度填报表";
  • 在数据里存放的应该是工作表列表,这里只放了一个进度填报表,虽然表名字没有出来。单元格数据用如下格式存放到单元格数据里面。也就是我们可以在后端将数据查出来然后存放到这里,然后前端页面就能看到后端传递渲染的数据
  • 单元格数据里放的是单元格列表,单元格的值是v下面的v里面
[{
    "r": 0, "c": 0, 
    "v": {"m": "dd", 
          "ct": {"fa": "General", "t": "g"}, 
          "v": "dd"}
  },
 {"r": 0, "c": 1, "v": {"m": "dd", "ct": {"fa": "General", "t": "g"}, "v": "dd"}},
 {"r": 0, "c": 2, "v": {"m": "b", "ct": {"fa": "General", "t": "g"}, "v": "b"}}]

效果如下图

将表格数据传递给后端保存到数据库中

现象:

在前端输入数据,点击保存按钮

 后段能在拼接的工作表数据里面获取到单元格数据

 

 再看看下代码

  • 在某个地方定义一个保存按钮,并给保存按钮绑定保存点击事件的函数
  • 当点击保存数据按钮时,触发执行函数,会获取到单元格数据,然后发送ajax请求,这里是post请求,但是我们将单元格数据和表id放到data参数下,它们会以?和&符号拼接到url后面,作为args参数,
  • 后端需要从args中获取到这两个值,其中一个就是单元格数据,这样我们就可以保存到数据库中了。这个url也可以不用写ip端口的

 

  <a class="btn btn-primary btn-rounded btn-sm" onclick="saveData()"><i class="fa fa-save"></i>&nbsp;&nbsp;<@ctx.i18n text = "保存数据"/></a>


$(function () {

    function saveData()
    {
        var celldata = (JSON.stringify(luckysheet.transToCellData(luckysheet.getLuckysheetfile()[0].data)));
        $.ajax({
            url:"http://127.0.0.1:5000/article/mcw",
            data:{"sheetData":celldata,"scheId":0},
            Type:"post",
            dataType:"json",
            success:function(res) {
                console.log(res);
            }
        });
    }
  • 我们再研究一下,当点击保存后,会将单元格中的数据按如下格式发送到请求的url。然后它对应的视图函数可以从args中获取sheetData参数的值,也就是保存的单元格数据。数据里面有两个都显示了单元格内容。
  • 由行数,列数和图片中数据填写位置得知,r就是行索引,c就是列索引,v就是就是value,value下面还有其它信息,v下面的m和v是单元格的具体内容,可能用v更好点吧。
  • 也就是我们从args中获取到这个数据,就可以保存到数据库了,
  • 由保存数据和渲染数据可以看出,二者数据结构基本差不多,那么是不是就可以直接将表格数据json存入到数据库,然后读取的时候直接从数据库读取渲染呢。回头验证
[{"r": 0, "c": 0, "v": {"m": "dd", "ct": {"fa": "General", "t": "g"}, "v": "dd"}},
 {"r": 0, "c": 1, "v": {"m": "dd", "ct": {"fa": "General", "t": "g"}, "v": "dd"}},
 {"r": 0, "c": 2, "v": {"m": "b", "ct": {"fa": "General", "t": "g"}, "v": "b"}}, 
 {"r": 1,"c": 1, "v": {"m": "小马","ct": {"fa": "General", "t": "g"}, "v": "小马"}}]

 在线表格中元素增删改,样式修改

这些修改我是放在跟options一起的函数里面,创建表后面才生效的,放在这这个function之外一直没生效。放在里面添加标签和修改样式都是生效的

不加safe

 

 渲染会有问题

 

 加上safe。正常渲染

 

 

 添加数据,点击保存

 

 数据库中有相同标题的,就是修改数据,如果没就是创建数据

 

 其它页面访问,可以访问到。会从数据库中将数据渲染到前端,但是我刚刚调整的单元格宽度并没有保存上
