                { id: 2, name: "Oranges" }
            ];
            $("#autocomplete").kendoAutoComplete({
                dataTextField: "name", // The widget is bound to the "name" field
                dataSource: data
            });
            $('#autocomplete').on('change', function() {
                var autoCompleteValue = $('#autocomplete').val();
                var autoCompleteText = $('#autocomplete').text();
                alert(autoCompleteValue + '->' + autoCompleteText);
            });

        });
    </script>
</body>
</html>

我希望在更改下拉列表时获取价值和文字。我选择苹果

我想要

autoCompleteValue = "1";
autoCompleteText = "Apples";

Answer 1

您可以稍微修改代码以实现解决方案：

<input id="autocomplete" />
<div id="result"></div>

$("#autocomplete").kendoAutoComplete({
    dataTextField: "name",
    select: function(e) {
        var dataItem = this.dataItem(e.item.index());            
        //output selected dataItem
        $("#result").html(kendo.stringify(dataItem)); // Bind html to see your selected text and value      
    },
    dataSource: {
        data: [
            { name: "Apples", value: 1 },
            { name: "Oranges", value: 2 },
            { name: "Bananas", value: 3 },
            { name: "Mangos", value: 4 }
        ]
    }
});

您可能需要更改数据源和自动填充功能，如下所示：

var items = new kendo.data.DataSource({
    transport: {
        read: {
            url     : "/Home/GetItems",
            type    : "POST",
            dataType: "json"
        }
    },
    schema   : {
        model: {
            id    : "id",
            fields: {
                id  : { type: "id" },
                name: { type: "string" }
            }
        }
    }
});

var autoComplete = $("#autocomplete").kendoAutoComplete({
    minLength      : 3,
    separator      : ", ",
    dataSource     : items,
    serverFiltering: true,
    dataTextField  : "name"
}).data("kendoAutoComplete");
