handsontable: hide some columns without changing data array/object

由 拈花ヽ惹草 提交于 2019-12-07 11:33:39
问题 I have a data to show in grid. I am using handsontable to show data. Each 3rd column is computed as difference of previous two (for example, 3rd column is rendered as the sum of 1st and 2nd column; this is done by custom renderer taking sum of i-1 and i-2 columns). This is my custom renderer for "difference" columns: var val1 = instance.getDataAtCell(row, col - 1), val2 = instance.getDataAtCell(row, col - 2), args = arguments; args[5] = val2 - val1; if (args[5] !== 0) { $(td).addClass('grid

Javascript Handsontable - Uncaught TypeError: Cannot read property 'insertBefore' of undefined

I literally copied the tutorial but the console (web developer console) gives me the following error: Uncaught TypeError: Cannot read property 'insertBefore' of undefined handsontable.full.js:4471 I link both the .css and the .js file correctly in the <head> tags.

问题 I want to refresh a handsontable grid. I have some columns with a dropdown filled with data of my database.

Add a table type to a JSON editor

I want to understand the code of this JSON editor and modify it. In directives.js , there is a piece of code that tries to construct templates: var switchTemplate = '<span ng-switch on="getType(val)" >' ... ... + '<span ng-switch-when="Boolean" type="boolean">' + '<input type="checkbox" ng-model="val" ng-model-onblur ng-change="child[key] = val">' + '</span>' ... ... + '</span>'; // display either "plus button" or "key-value inputs" var addItemTemplate = '<div ng-switch on="showAddKey" class="block" >' + '<span ng-switch-when="true">'; if (scope.type == "object"){ // input key addItemTemplate

Retrieving a hidden header inside a sorted handsontable instance

由 五迷三道 提交于 2019-12-05 01:35:56
When using Handsontable , it seems hard to retrieve the header of a row from a contextual menu. Consider the following data source: var data = function () { return [["1212", "roman", "i", "ii", "iii"], ["3121", "numeric", 1, 2 ,3], ["4126", "alpha", 'a', 'b', 'c']]; }; It is possible to create a Handsontable instance that displays all of the data but the first two "columns", and that has a contextual menu as following: // Settings to display all columns but the first two var dataCols = [] for(var i=2; i<data()[0].length; i++) { dataCols.push({ data: i }) } // Instance creation var hot = new
