Handsontable:如何在渲染函数中更改单元格值 [英] Handsontable : how to change cell value in render function

问题描述

我有类似的代码:

<script>
$(document).ready(function () {
    var data = @Html.Raw(ViewBag.Data);

function sumPreviousValues(instance, td, row, col, prop, value, cellProperties) {
  Handsontable.renderers.TextRenderer.apply(this, arguments);
    td.val = 'SUM SEVERAL PREVIOUS CELLS';
}

     container = document.getElementById('example1'),
      settings1 = {
        data: data,
        colHeaders: @Html.Raw(ViewBag.TableHeader),
        cells: function (row, col, prop) {
            var cellProperties = {};

            if (col == 16) {
                cellProperties.renderer = sumPreviousValues;
            }
    return cellProperties;
        }
      },

    hot = new Handsontable(container,settings1);
    hot.render();

关键是修改功能sumPreviousValues()

但是我不知道如何访问td值?以及是否可以访问其他单元格的值，例如td[index]. 任何的想法?我在文档中找不到选项.

But I dont know how to access the td value ? and if it is possible to access other cells' value like td[index]. Any idea? I didn't find options in documentation.

谢谢

推荐答案

我想我知道您想要做什么，这是一个简单的解决方案:

I think I understand what you want to do and here is a simple solution:

在自定义渲染器内部，您可以调用:

From inside the custom renderer, you can call:

instance.getDataAtCell(row, col);

这将为您提供row,col处单元格的数据(值).希望能有所帮助:)

This will give you the data (value) of the cell at row,col. Hope that helps :)

此外，要访问当前td的值，您只需使用value变量:P查看函数定义.您实际上是在传递它，并且可以使用它.

Also, to access the value at the current td, you just use the value variable :P Look at the function definition. You are literally passing it in and is available to you.
