kendoUI系列教程之combobox下拉列表框

combobox下拉列表与autocomplete自动补齐和DropDownList 下拉菜单非常相似，DropDownList其实就是select，只有下拉选择。autocomplete是输入内容后匹配生成下拉来选择。combobox就是他们俩的结合体，即可下拉选择，也可输入自动匹配。他们的用法与属性很多是一样的。以下是一个联动ajax的效果：

<div class="demo-section">
<h2>View Order Details</h2>
<p>
	<label for="categories">Categories:</label><input id="categories" style="width: 300px" />
</p>
<p>
	<label for="products">Products:</label><input id="products" disabled="disabled" style="width: 300px" />
</p>
<p>
	<label for="orders">Orders:</label><input id="orders" disabled="disabled" style="width: 300px" />
</p>
<button class="k-button" id="get">View Order</button>
</div>
<script>
	$(document).ready(function() {
		var categories = $("#categories").kendoComboBox({
			filter: "contains",
			placeholder: "Select category...",
			dataTextField: "CategoryName",
			dataValueField: "CategoryID",
			dataSource: {
				type: "odata",
				serverFiltering: true,
				transport: {
					read: "http://demos.kendoui.com/service/Northwind.svc/Categories"
				}
			}
		}).data("kendoComboBox");

		var products = $("#products").kendoComboBox({
			autoBind: false,
			cascadeFrom: "categories",
			filter: "contains",
			placeholder: "Select product...",
			dataTextField: "ProductName",
			dataValueField: "ProductID",
			dataSource: {
				type: "odata",
				serverFiltering: true,
				transport: {
					read: "http://demos.kendoui.com/service/Northwind.svc/Products"
				}
			}
		}).data("kendoComboBox");

		var orders = $("#orders").kendoComboBox({
			autoBind: false,
			cascadeFrom: "products",
			filter: "contains",
			placeholder: "Select order...",
			dataTextField: "Order.ShipCity",
			dataValueField: "OrderID",
			dataSource: {
				type: "odata",
				serverFiltering: true,
				transport: {
					read: "http://demos.kendoui.com/service/Northwind.svc/Order_Details?$expand=Order"
				}
			}
		}).data("kendoComboBox");

		$("#get").click(function() {
			var categoryInfo = "\nCategory: { id: " + categories.value() + ", name: " + categories.text() + " }",
				productInfo = "\nProduct: { id: " + products.value() + ", name: " + products.text() + " }",
				orderInfo = "\nOrder: { id: " + orders.value() + ", name: " + orders.text() + " }";
			alert("Order details:\n" + categoryInfo + productInfo + orderInfo);
		});
	});
</script>
