Question

我在ASP.net webforms中有一个项目。我有一个表格，在那个表格中我有一个

<asp:ImageMap ID="imCarDiagram" runat="server" ImageUrl="~/Content/Resources/car-diagram.png" HotSpotMode="PostBack">
    <asp:PolygonHotSpot Coordinates="106,42,107,25,147,18,211,14,335,25,336,41,335,43,328,41,323,32,225,24,118,33,114,44,106,42" AlternateText="Front bumper" PostBackValue="FrontBumper" HotSpotMode="PostBack" />
    <%--<asp:PolygonHotSpot Coordinates="113,81,138,49,303,51,325,80,297,70,143,69,113,81" AlternateText ="Front of the car" PostBackValue="FrontOfTheCar" HotSpotMode="PostBack" />--%>
    <asp:PolygonHotSpot Coordinates="145,63,145,55,166,55,166,63,145,63" AlternateText="Left Headlight" PostBackValue="LeftHeadlight" HotSpotMode="PostBack" />
    <asp:PolygonHotSpot Coordinates="272,63,272,55,292,55,292,63,272,63" AlternateText="Right Headlight" PostBackValue="RightHeadlight" HotSpotMode="PostBack" />
    <asp:PolygonHotSpot Coordinates="105,185,135,155,138,134,110,105,110,86,122,75,142,70,153,118,159,176,105,185" AlternateText="Left Fender" PostBackValue="LeftFender" HotSpotMode="PostBack" />
    <asp:PolygonHotSpot Coordinates="142,69,154,125,158,176,282,177,283,129,294,69,142,69" AlternateText="Hood" PostBackValue="Hood" HotSpotMode="PostBack" />
    <asp:PolygonHotSpot Coordinates="281,177,282,129,294,69,315,75,329,87,329,105,311,119,299,142,303,162,333,185,281,177" AlternateText="Right Fender" PostBackValue="RightFender" HotSpotMode="PostBack" />
    <asp:CircleHotSpot X="101" Y="144" Radius="30" AlternateText="Left Wheel" PostBackValue="LeftWheel" HotSpotMode="PostBack" />
    <asp:CircleHotSpot X="335" Y="145" Radius="30" AlternateText="Right Wheel" PostBackValue="RightWheel" HotSpotMode="PostBack" />
</asp:ImageMap>

在前端，我使用imagemapster可以突出显示多个区域。一切正常，我可以选择汽车图上的多个区域。当我点击提交时，如何在我的代码中发送所选区域（onclick =＆＃34; submit_event＆＃34;我在哪里保存数据）？

<asp:Button runat="server" ID="btnSave" Text="Save" OnClick="btnSave_Click" class="btn submit action-button btn-success" />

protected void btnSave_Click(object sender, EventArgs e)
{
    SaveClaim(code that is saving the rest of the fields);

}

如何在选定区域引入btnSave_Click事件？

管理以解决问题。的解决方案：添加一个不可见的输入，并使用所选区域的枚举填充该输入。然后使用JS用枚举填充该输入。

var img = $('#img'); $(img).mapster({ onStateChange: function(){ document.getElementById('#input_text').value = img.mapster('get') } }); });
