正如我在标题中提到的那样，一旦我单击“编辑”按钮，就需要为该行的第一个单元格设置可编辑的false。但是，当向表中添加新行（插入表行）时，我不需要应用此方案。我发现实现此目标的最合适方法是通过禁用和启用 ShieldGrid的 events => edit和insert函数中的列编辑。
此处显示了到目前为止的方法：
$("#grid1").shieldGrid({
dataSource: {
data: products,
schema: {
fields: {
id: { path: "ProductID", type: Number},
ProductName: { path: "ProductName", type: String },
quantity: { path: "SupplierID", type: Number },
price: { path: "UnitPrice", type: Number },
units: { path: "UnitsInStock", type: Number }
}
}
},
events: {
edit: function(e) {
//disabling here.....
var first_cell= e.row[0].firstElementChild;
alert("Edit event is fired");
},
insert: function(e) {
//enabling here.....
var first_cell= e.row[0].firstElementChild;
alert("Insert event is fired");
}
},
rowHover: false,
columns: [
{ field: "ProductName", width: "200px" },
{ field: "quantity" },
{ field: "price" },
{ field: "units" }
],
editing: {
enabled: true,
type: "row",
confirmation: {
"delete": {
enabled: true,
template: "Delete row {0}?"
}
}
}
});
通过editorCreating事件，我可以通过以下方式轻松禁用列编辑：
editorCreating: function (e) {
if (e.field == "columnName") {
e.options = {enabled: false};
}
但是该方法不适用于edit事件。 （e.options在插入和编辑函数中调用时在控制台日志中未定义），并且editorCreating也在初始化列编辑器之前被触发，这无法满足我的要求。 ：（
console.log(e.row[0].firstElementChild)返回：

但是从那里我找不到禁用列编辑的任何可行解决方案。任何建议都是可取的。
