Default values for the fields should be set in the schema.model definition of the dataSource:
字段的默认值应在数据源的 schema.model 定义中设置：
schema.model Object kendo.data.ModelThe data item (model) configuration.
schema.model Object kendo.data.Model数据项（模型）配置。
If set to an object, the Model.define method will be used to initialize the data source model.
如果设置为对象，则 Model.define 方法将用于初始化数据源模型。
If set to an existing kendo.data.Model instance, the data source will use that instance and will not initialize a new one.
如果设置为现有的 kendo.data.Model 实例，数据源将使用该实例并且不会初始化新的实例。
Example - set the model as a JavaScript object
示例 - 将模型设置为 JavaScript 对象
<script>
var dataSource = new kendo.data.DataSource({
schema: {
model: {
id: "ProductID",
fields: {
ProductID: {
//this field will not be editable (default value is true)
editable: false,
// a defaultValue will not be assigned (default value is false)
nullable: true
},
ProductName: {
//set validation rules
validation: { required: true }
},
UnitPrice: {
//data type of the field {Number|String|Boolean|Date} default is String
type: "number",
// used when new model is created
defaultValue: 42,
validation: { required: true, min: 1 }
}
}
}
}
});
</script>
Example - set the model as an existing kendo.data.Model instance
示例 - 将模型设置为现有的 kendo.data.Model 实例
<script>
var Product = kendo.data.Model.define({
id: "ProductID",
fields: {
ProductID: {
//this field will not be editable (default value is true)
editable: false,
// a defaultValue will not be assigned (default value is false)
nullable: true
},
ProductName: {
//set validation rules
validation: { required: true }
},
UnitPrice: {
//data type of the field {Number|String|Boolean|Date} default is String
type: "number",
// used when new model is created
defaultValue: 42,
validation: { required: true, min: 1 }
}
}
});
var dataSource = new kendo.data.DataSource({
schema: {
model: Product
}
});
</script>
