我试图在我的剑道网格列中使用kendoDropDownList但它无效。
我跟随this post上的示例,但我想我错过了一些东西。
KendoGrid DataSource:
var comboDataSource = new kendo.data.DataSource({
transport: {
read: {
type: "GET",
crossDomain: true,
url: url,
dataType: "json"
}
},
schema: {
data: "data",
model: {
id: "id",
fields: {
id: { editable: false, nullable: true },
typeId: { field: "typeId", defaultValue: 1 },
value: { type: "number", validation: { required: true } }
}
}
}
});
KendoDropDownList DataSource:
var typesComboDataSource = new kendo.data.DataSource({
transport: {
read: {
type: "GET",
crossDomain: true,
url: url,
dataType: "json"
}
},
schema: {
data: "data",
model: {
id: "typeId",
fields: {
typeId: { editable: false, nullable: true },
description: { validation: { required: true } }
}
}
}
});
KendoGrid:
$("#grid").kendoGrid({
editable: true,
toolbar: ["create", "save", "cancel"],
dataSource: comboDataSource,
columns: [{
title: "Type",
field: "typeId",
editor: typeDropDownEditor,
template: "#=getType(typeId)#"
}, {
title: "Value",
field: "value"
}]
})
function typeDropDownEditor(container, options) {
$('<input data-bind="value:' + options.field + '"/>')
.appendTo(container)
.kendoDropDownList({
dataTextField: "description",
dataValueField: "typeId",
dataSource: typesComboDataSource,
change: function (e) {
var dataItem = e.sender.dataItem();
options.model.set("typeId", dataItem.typeId);
}
});
}
function getType(typeId) {
var data = typesComboDataSource.data();
for (var idx = 0, length = data.length; idx < length; idx++) {
if (data[idx].typeId === typeId) {
return data[idx].description;
}
}
}
出于某种原因,我收到了错误ReferenceError: getType is not defined
而且我不知道原因。
如果我将函数直接放在模板上,我的数据会被加载,但类型字段会显示为undefined
。我的typesComboDataSource
没有触发。
$("#grid").kendoGrid({
editable: true,
toolbar: ["create", "save", "cancel"],
dataSource: comboDataSource,
columns: [{
title: "Type",
field: "typeId",
editor: typeDropDownEditor,
template: function getType(typeId) {
var data = typesComboDataSource.data();
for (var idx = 0, length = data.length; idx < length; idx++) {
if (data[idx].typeId === typeId) {
return data[idx].description;
}
}
}
}, {
title: "Value",
field: "value"
}]
});
有人可以帮帮我吗? 谢谢!

您的模板函数在运行时在JQuery代码块范围之外进行计算,因此它不知道代码实际运行时getType是什么。将typeDropDownEditor()和getType()函数移到JQuery块之外,你应该好好去。
