Getting the number of field definitions from an infotable

kahmeng96 — Tue, 29 Oct 2019 08:15:23 GMT

Hi all, I am trying to get the number of field definitions from my infotable as shown.

In this case, I want the number of field definitions to return 4. I've tried using getFieldCount() but it doesn't seem to work, any help will be greatly appreciated!

Hi @Constantine, thanks for reply. I am actually using an IDE to create a custom widget so your solution might not be applicable. Therefore, I will be using mine as shown in the code below.

this.updateProperty = function (updatePropertyInfo) { var widgetProperties = this.properties; var dataRows = updatePropertyInfo.ActualDataRows; var nRows = dataRows.length; var rowData = new Array(); for (var i = 0; i < nRows; i++) { rowData.push(dataRows[i]); } } console.log(Object.keys(rowData[0]).length); //returns 4
