Question

您好我正在使用Kendo UI，特别是使用kendoAutoComplete组件。我可以获得自动完成字段的值，但我需要与之关联的id值。

$("#autocomplete").kendoAutoComplete({
    minLength: 3,
    dataTextField: "Name", //JSON property name to use
    dataValueField: "Id",
    dataSource: respuestaSolicitud
});

我抓住了这种方式

var x=$('#autocomplete').data("kendoAutoComplete");

变量x返回[对象]

document.getElementById('autocomplete').value

dataTextField: "Name"的返回值但我需要整数值dataValueField: "Id"

Answer 1

$(document).ready(function () {
            var data = [{Name:"aaaa",Id:1111},{Name:"bbbb",Id:2222}
            ];

            //create AutoComplete UI component
            $("#countries").kendoAutoComplete({
                dataSource: data,
                change: function(e){
                    alert(this.dataItem().Id)
                },
                dataTextField: "Name", //JSON property name to use
                dataValueField: "Id",
                filter: "startswith",
                placeholder: "Select country...",
                separator: ", "
            });
        });

        function _getValue(){

            alert($("#countries").data("kendoAutoComplete").value())
        }

.info {
            display: block;
            line-height: 22px;
            padding: 0 5px 5px 0;
            color: #36558e;
        }

        #shipping {
            width: 482px;
            height: 152px;
            padding: 110px 0 0 30px;
            background: url('../content/web/autocomplete/shipping.png') transparent no-repeat 0 0;
            margin: 100px auto;
        }

        .k-autocomplete
        {
            width: 250px;
            vertical-align: middle;
        }

        .hint {
            line-height: 22px;
            color: #aaa;
            font-style: italic;
            font-size: .9em;
            color: #7496d4;
        }

<div id="example">

    <div id="shipping">
        <button onclick="_getValue()">press me</button>

        <label for="countries" class="info">Choose shipping countries:</label>

        <input id="countries" />

        <div class="hint">Start typing the name of an European country</div>

    </div>

您可以使用下划线查找结果

var selected = $("#countries").data("kendoAutoComplete").value();
var dataItem = _.find($("#$("#countries").data("kendoAutoComplete").dataSource.data(),function(element){
return element.Name=== selected;
})

alert (dataItem.Id)

另一种方法是使用更改事件，然后在事件中使用this.dataItem（）获取完整元素，以便获得Id

this.dataItem().Id

如何捕获kendoUI的自动完成组件的DataValueField？
