JQuery Easyui IE browser appears ' Rowspan ' is empty or not an object

Easyui 1.4.2.


When using the DataGrid control with jquery Easyui, you use the way you specify columns dynamically, with the following code:

$ ("#topApList"). DataGrid ({columns:[[
{field: ' AAA ', title: ' AAA ', align: ' center ', width:130},
{field: ' BBB ', title: ' BBB ', align: ' center ', width:100} ,

An error occurred while opening the page in the IE8 browser:' Rowspan ' is empty or not an object, ' Colspan ' is empty or not an object.

There are no errors in Firefox, Safari, Chrome, and the page is displayed properly.

Analysis Code:

Jquery.easyui.mini.js code, highlighted in the place where there is a null pointer exception:

for (var j = 0; J < Cols.length; J + +) {
var col = cols[j];
var attr = "";
if (Col.rowspan) {
attr + = "rowspan=\" "+ Col.rowspan +" \ ";
if (Col.colspan) {
attr + = "colspan=\" "+ Col.colspan +" \ ";


After the last field, a comma appears, causing the browser to calculate a cols.length of 3 (with an actual value of 2) and a null pointer exception when accessing COLS[2].


Remove the comma after the last field.


The above error does not appear in IE.
