我如何从kendo comboBox中获取选择值

Question

我已经实现了剑道ComboBox,但努力获得选定的价值....

  $("#_FeeScheme_Input").kendoComboBox({
        minLength: 1,
        filter: 'contains',
        dataTextField: "FeeSchemeDescription",
        dataValueField: "FeeSchemeID",
        select: onSelect,
        dataSource: {
            type: "json",
            serverFiltering: false,
            transport: {
                read: "/Qualification/GetAllFeeScheme_JSON"
            },
        }
    });

...

 function onSelect(e) {

        var dataItem = this.dataItem(e.item.index());

        alert("value " + dataItem.text); //NOT WORKING... RETURN NULL VALUE            

    };

剃刀代码

 <div class="form-group">
                @Html.LabelFor(model => model._FeeScheme.FeeSchemeDescription, new { @class = "control-label col-md-3" })
                <div class="col-md-6">
                    @Html.TextBoxFor(model => model._FeeScheme.FeeSchemeDescription, new { id = "_FeeScheme_Input" })
                    @Html.ValidationMessageFor(model => model._FeeScheme.FeeSchemeDescription)
                </div>
 </div>

Answer 1

在Asp.net MVC中:

var c = $('#MyCombo');

// to get selected id
c.val() // and also
c.data('kendoComboBox').value()

// to get selected text
c.data('kendoComboBox').text()

// to get selected item index
c.data('kendoComboBox').select()

// to set selected item e.g. 3
c.data('kendoComboBox').select(2)

来自 kendo comboBox 的 getter/setter 是 kendoComboBox 'class' 的一部分。

您可以根据需要使用this.value()或this.text()。

$("#_FeeScheme_Input").kendoComboBox({
    minLength: 1,
    filter: 'contains',
    dataTextField: "FeeSchemeDescription",
    dataValueField: "FeeSchemeID",        
    dataSource: {
        type: "json",
        serverFiltering: false,
        transport: {
            read: "/Qualification/GetAllFeeScheme_JSON"
        },
    },
    change: function(){
       alert("value " + this.value());
    }
});
