【中文标题】Handsontable JSON 返回未定义

【英文标题】：Handsontable JSON returns undefined

【问题描述】：

我对 Handsontable 和 JS，尤其是 JSON 的使用相当陌生。任何帮助，将不胜感激。在第 131 行的调试器中，'data[row].temp_source_data' = undefined。 我似乎无法弄清楚为什么没有返回值。我已经包含了 js 文件。谢谢！

var hot;
var hotContainer;
var invalidCells = 0;
var forceRender = false;
var vendorSites = [];
var defaultVendorSite;
var gValidPo = true;
var supplier_number = [];
var data = [];
var errorIcon = '<i class="fa fa-exclamation-triangle fa-lg" style="color:red;"></i>';

// Create empty handsontable instance
function createEmptyHot(pRegion)
  setHotContainer(pRegion);
  hotContainer.height = getMaxHeight();
  assembleHot(hotContainer, data, getMaxHeight(hotContainer));


function setHotContainer(pId)
    hotContainer = document.getElementById(pId);


// Get max height of the handsontable instance
function getMaxHeight()
  var maxHeight = (window.innerHeight - jQuery(hotContainer).offset().top * .8);
  return maxHeight;


//Assemble the handsontable instance
function assembleHot(pContainer, pData, pHeight)
    // Hook functions
    // Handle before change event
    function handleBeforeChange(changes, source)

【参考方案1】：

您是否尝试过使用hot.getSourceData() 而不是hot.getData()？

他们最近在最新版本中更改了 hot.getData() 的功能，这给其他人带来了类似的问题。

【讨论】：

不，我没有。感谢您的提醒！

没问题！很高兴这是一个简单的修复。 :)
