在 NodeJS 中使用 Tabulator 和 ExpressJS

Question

我正在尝试安装 Tabulator (http://tabulator.info/docs/4.0/quickstart) 的默认示例。 我在我的 NodeJS 项目中安装了 Tabulator。

我的 index.js 文件中的路由定义如下所示：

app.get("/", (req, res) => {
    var table = new tabulator("#example-table", {
        height:205,
        layout:"fitColumns", //fit columns to width of table (optional)
        columns:[ 
            {title:"Name", field:"name", width:150},
            {title:"Age", field:"age", align:"left", formatter:"progress"},
            {title:"Favourite Color", field:"col"},
            {title:"Date Of Birth", field:"dob", sorter:"date", align:"center"},
        ],
        rowClick:function(e, row){
            alert("Row " + row.getData().id + " Clicked!!!!");
        },
      });
  
      var tabledata = [
      {id:1, name:"Oli Bob", age:"12", col:"red", dob:""},
      {id:2, name:"Mary May", age:"1", col:"blue", dob:"14/05/1982"},
      {id:3, name:"Christine Lobowski", age:"42", col:"green", dob:"22/05/1982"},
      {id:4, name:"Brendon Philips", age:"125", col:"orange", dob:"01/08/1980"},
      {id:5, name:"Margret Marmajuke", age:"16", col:"yellow", dob:"31/01/1999"},
      ];
    res.render("index", { title: "Home"});
});

然后我在 index.pug 中添加了一个 div：

div.example-table

但是，我收到以下错误：

ReferenceError: document is not defined
    at Tabulator.initializeElement (C:\Users\SESA509216\Box\Perso\Scripts\LMS\Audit-Trail\node_modules\tabulator-tables\dist\js\tabulator.js:9223:19)

    at next (C:\Users\SESA509216\Box\Perso\Scripts\LMS\Audit-Trail\node_modules\express\lib\router\index.js:275:10)

我猜，Tabulator 应该以某种方式在客户端初始化。但我不知道怎么...

我解决了我的问题。

我将 tabulator-tables css & js 路径加入到 index.js 中的应用配置中：

app.use(express.static(path.join(__dirname, "node_modules/tabulator-tables/dist/css")));
app.use(express.static(path.join(__dirname, "node_modules/tabulator-tables/dist/js")));

然后，我在前端导入了制表符 css 和 js 文件：

link(rel="stylesheet" href="tabulator.min.css")
script(type='text/javascript' src="tabulator.min.js")

最后，我将示例脚本复制到我的页面中：

div.example-table(id="example-table")
    script.  
      //create Tabulator on DOM element with id "example-table"
      var table = new Tabulator("#example-table", {
        height:205, // set height of table (in CSS or here), this enables the Virtual DOM and improves render speed dramatically (can be any valid css height value)
        layout:"fitColumns", //fit columns to width of table (optional)
        columns:[ //Define Table Columns
          {title:"Name", field:"name", width:150},
          {title:"Age", field:"age", align:"left", formatter:"progress"},
          {title:"Favourite Color", field:"col"},
          {title:"Date Of Birth", field:"dob", sorter:"date", align:"center"},
        ],
        rowClick:function(e, row){ //trigger an alert message when the row is clicked
          alert("Row " + row.getData().id + " Clicked!!!!");
        },
      });
      
      //define some sample data
      var tabledata = [
        {id:1, name:"Oli Bob", age:"12", col:"red", dob:""},
        {id:2, name:"Mary May", age:"1", col:"blue", dob:"14/05/1982"},
        {id:3, name:"Christine Lobowski", age:"42", col:"green", dob:"22/05/1982"},
        {id:4, name:"Brendon Philips", age:"125", col:"orange", dob:"01/08/1980"},
        {id:5, name:"Margret Marmajuke", age:"16", col:"yellow", dob:"31/01/1999"},
      ];
      
      //load sample data into the table
      table.setData(tabledata);

非常感谢您的帮助！

看起来您正在尝试在控制器的响应中使用 Tabulator。

Tabulator 设计为在客户端运行，而不是在服务器端运行。您需要返回一些带有脚本标签的 HTML，然后在 DOM 节点上构建表格。

您还使用小写“T”实例化制表符，它应该是new Tabulator

我建议您需要做的是创建一个 HTML 页面来显示表格，例如 http://tabulator.info/basic/4.8 的源代码就可以了，尽管您还需要提供源 JS 和 CSS 文件才能使演示工作，或者，您可以将本地文件路径更改为 CDN Links 以进行快速演示。

然后您需要使用 ExpressJS 提供此页面，使用 sendFile 函数和 html 文件的路径

// viewed at http://localhost:8080
app.get('/', function(req, res) {
    res.sendFile(path.join(__dirname + '/index.html'));
});

要将表数据从节点传递到 pug 文件中的脚本，请执行以下操作：

// node index.js
let data = [
    {id : 1, name : 'Adam', zip : '11101'},
    {id : 2, name : 'Bob', zip : '95134'}
];
res.render('table.pug', { table_data: data });

// table.pug
div.example-table(id="example-table")
      script.
        var table = new Tabulator("#example-table", {
          columns:[
            {title:"Name", field:"name"},
            {title:"ZIP", field:"zip"}
          ]
        });

        //load sample data into the table
        table.setData(!{JSON.stringify(table_data)});
