javascript - 制表器 - 如何仅提取数据并保存为 json 对象

问题描述

有没有办法将制表器表中的所有数据保存到 jquery/javascript 中的变量中？我注意到他们有一个

table.downloadToTab("json");

很酷的方法，但我不想打开新的浏览器，我只想保存到一个变量中。

我知道我可以编写自己的 javascript / jquery 代码来循环遍历行和单元格，但看起来他们没有使用传统的表格，<tr>但<td>一切都是具有特定类名的。

例如，这是为制表符表中的一行数据创建的所有 HTML：

<div class="tabulator-row tabulator-selectable tabulator-row-odd" role="row" style="padding-left: 30px;">
   <div class="tabulator-cell tabulator-row-handle tabulator-frozen tabulator-frozen-left" role="gridcell" title="" style="width: 30px; position: absolute; left: 0px; height: 29px;">
      <div class="tabulator-row-handle-box">
         <div class="tabulator-row-handle-bar"></div>
         <div class="tabulator-row-handle-bar"></div>
         <div class="tabulator-row-handle-bar"></div>
      </div>
      <div class="tabulator-col-resize-handle"></div>
      <div class="tabulator-col-resize-handle prev"></div>
   </div>
   <div class="tabulator-cell" role="gridcell" tabulator-field="id" title="" style="width: 150px; height: 29px;">

解决方案

您可以使用制表符的getData()方法：

var array = table.getData();

这会将所有表的数据作为二维数组返回。如果您只想获取当前过滤的数据（对用户可见），则true作为参数传递：

var array = table.getData(true);

如果您需要以某种方式传输/保存这些数据，您可以使用本机JSON.stringify()函数生成 JSON：

var json = JSON.stringify(array);
