我是新的jquery，我知道很多类似的职位有相同的，但它不工作，在我的情况不知道为什么？无论如何，让我解释一下我的场景，我正在调用下拉绑定方法网格点击事件，我只想调用一次，我尝试了这样。请帮帮我

$(function () {
            $("[id*=dgDepots]").one('click', function () {
                BindLocationsHeader();
            });
        });

• • 功能**

function BindLocationsHeader(data, status) {

    if (alldata != undefined && alldata.Locations != undefined) {
        var divisionCode = $('#ddlDivision').val();
        var regionCode = $('#ddlRegion').val();
        $('#ddlLocationH').empty();
        d = alldata.Locations;
        $("[id$='ddlLocationH']").append($("<option>select</option>").val("0").html("Select"));
        for (i = 0; i < d.length; i++) {
            if (divisionCode == d[i].DivisionCode && regionCode == d[i].RegionCode) {
                var ddlVal = d[i].LocationCode;
                var ddlText = d[i].LocationName;
                $("[id$='ddlLocationH']").append($("<option ExchangeRate='" + d[i].ExchangeRate + "' NoOfDecimals='" + d[i].NoOfDecimals + "' CurrencyCode='" + d[i].CurrencyCode + "' >select</option>").val(ddlVal).html(ddlText));
            }
        }
    }
}

网格视图

<dx:ASPxGridView ID="dgDepots" runat="server" ClientInstanceName="grid"
        Width="100%"
        OnRowDeleting="dgDepots_RowDeleting" OnRowInserting="dgDepots_RowInserting" OnRowUpdating="dgDepots_RowUpdating">
        <Columns>
            <dx:GridViewDataColumn FieldName="LocationCode" VisibleIndex="0">

                    <asp:DropDownList ID="ddlLocationH" class="width50p input-tb" runat="server"></asp:DropDownList>

            </dx:GridViewDataColumn>
            <dx:GridViewDataColumn FieldName="GLCode" VisibleIndex="2">
                <EditItemTemplate>
                    <%-- <select id="ddlGLCode" name="ddlGLCode" class="width50p input-tb"></select>--%>
                    <asp:DropDownList ID="ddlGLCode" class="width50p input-tb" runat="server"></asp:DropDownList>
                    &nbsp;<span><img src="/Images/icon_required_field.gif" /></span>
                </EditItemTemplate>
            </dx:GridViewDataColumn>
            <dx:GridViewCommandColumn ShowNewButton="true" ShowEditButton="true" ShowDeleteButton="true" VisibleIndex="2">
            </dx:GridViewCommandColumn>

        </Columns>

在这个网格点击我想填充下拉列表值，我可以做同样的使用上述代码，但无法防止双击事件
但是在这种情况下，下拉列表没有绑定，控制台上没有出现任何错误。有谁能帮我做同样的事吗
