选择单元格的奇怪行为

Question

我注意到 onSelectCell 中有一个奇怪的行为，而 cellEdit: true。

我在一个简单的表单上有 2 个网格，第二个网格在用户从第一个网格中选择一行后加载。两个网格都将 cellEdit 设置为 true，我使用 onSelectCell 从第一个网格中捕获 rowid，因此我可以调用一个方法来检索相应的数据。

奇怪的行为是：

在第一行选择它返回 rowid = undefined ！

On first cell select

当我从第一个网格中选择另一行时，onSelectCell 事件将前一行值分配给 rowid。

On second cell select

这种行为正常吗？？我在文档中阅读了它（仅适用于不可编辑的单元格；在选择单元格后触发）这正是我想要它做的事情。

// First Grid ...

                alert(validator + ' - ' + selectedCode);
                if (validator == 'N' && validator != undefined) {
                    paGrid.jqGrid('setCell', 3, 'Account', '', 'not-editable-cell');
                    paGrid.jqGrid('setCell', 3, 'AccountName', paGrid.jqGrid("getCell", 3, 'AccountName') + " - Account can't be changed");
                }
            }
        })

我也包含了网格的代码，以防我犯了任何错误，它可能是-_-

感谢您的宝贵时间。

您似乎正在设置selectedCode 和validator 变量第二个网格的gridComplete 事件被触发。尝试更改顺序：

onSelectCell: function (rowid, celname, value, iRow, iCol) {
    // here i'm assigning the rowid to a global variable
    selectedCode = rowid;
    validator = $.parseJSON(ProductCode.Main.AccountValidator(rowid).responseText).data[0].CanChangeAccount;
    // do this last since it depends on the variables above
    ProductCode.Main.populateProductAccounts(rowid);
},
