Create custom editors for jqxGrid. The "First Name" and "Last Name" columns use the jqxInput widget as a cell editor. The "Products" column use a jqxDropDownList widget with enabled Checkboxes as an editor. The "Quantity" column's editor is jqxSlider.
A live JavaScript/jQuery example of jqxGrid, the jQWidgets Grid component, with its complete source code below. It is one of 139 jqxGrid demos for jQuery.
selectionmode property – Sets or gets the selection mode.height property – Sets or gets the Grid's height.width property – Sets or gets the Grid's width.columns property – Sets the Grid columns.editable property – The editable property enables or disables the Grid editing feature.source property – Sets and gets the source.To run it in your own page, load jqx.base.css, a theme and the library files below from npm (npm install jqwidgets-scripts) or the jsDelivr CDN, then add the markup and the script. jQuery is not required: jqxcore.js provides $. Getting started with jqxGrid shows the setup step by step.
The page loads jqx.base.css, a theme and these library files: jqxcore.js, jqxdata.js, jqxbuttons.js, jqxscrollbar.js, jqxmenu.js, jqxgrid.js, jqxgrid.edit.js, jqxgrid.selection.js, jqxlistbox.js, jqxdropdownlist.js, jqxcheckbox.js, jqxinput.js, jqxslider.js.
It also loads helper scripts of this demo site, which are not part of the library: demos.js (getWidth() and other layout helpers), generatedata.js (generatedata(), random sample rows).
$(document).ready(function () {
// prepare the data
var data = generatedata(200);
var source =
{
localdata: data,
datatype: "array",
updaterow: function (rowid, rowdata, commit) {
// synchronize with the server - send update command
// call commit with parameter true if the synchronization with the server is successful
// and with parameter false if the synchronization failder.
commit(true);
