未捕获的TypeError：无法读取未定义的属性“模板”

我正在使用剑道网格。

我想在编辑时禁用列。（不是在我添加新记录时）。编辑时编写代码

function onEdit(e) {
    var indexCell = 1;
    var grid = $('#consumablesGrid').data('kendoGrid');


    if (e.model.id) { // when Editing the id is defined
        if (indexCell != 'undefined' && grid.columns[indexCell].title == "Consumable") {
            grid.closeCell();    
        }
    }
}

但在执行"Uncaught TypeError: Cannot read property 'template' of undefined "时会显示grid.closeCell()。

为了更好地理解，我将包括我的完整网格条件。

function ConsumableManager() {
    $("#consumablesGrid").kendoGrid({
        dataSource: {

            transport: {
                read: {
                    url: "GetConsumablesGrid",
                    type: "POST",
                    contentType: "application/json",
                    dataType: "json"
                },

                update: {

        },
        columns:
        [

            { field: "ConsumablesID", width: 50, hidden: true, title: "ID" },
            { field: "Consumable", width: 200, title: "Consumable", editor: ConsumablesDropDownEditor },
            { field: "UnitCost", width: 100, title: "Unit Cost" },
            { field: "Currency", width: 200, title: "Currency", editor: CurrencyUnitDropDownEditor },
             { field: "ContractID", width: 85, hidden: true, title: "ContractID" },

            { command: ["edit", "destroy"], title: "Action", width: "175px" }
        ]
    });


    $("#consumablesGrid").data("kendoGrid").dataSource.read();
}

任何人都有想法为什么会这样。我怎么能这样做请回复。

1.我有一个网格

2.编辑时我想要编辑（错误）（不添加）

Answer 1

你可能有一个新的jquery版本：http://docs.telerik.com/kendo-ui/getting-started/javascript-dependencies#jquery-version

Answer 2

当前的Kendo UI支持jquery 1.9.1。如果您将更高版本的jquery与kendo一起使用，则可能会遇到closeCell()的问题。

要修复（解决）此问题，您可以使用

$('#consumablesGrid').getKendoGrid().trigger('cancel')

而不是grid.closeCell()

Answer 3

这取决于jquery版本。为避免此问题，您可以使用此脚本

function onEdit(e) {
    if (!e.model.isNew() && (e.model != 'undefined') && (e.model != null)) {
        e.container.find("input[name=GroupName]").hide(); // To hide only the value of the column when updating the row
      //  e.container.find("#GroupName").parent().hide().prev().hide(); //to hide completely the column (value + structure + title name)
    }    
}

Kendo Grid显示错误“Uncaught TypeError：无法读取未定义的属性'模板'”
