<asp:checkBoxlist runat="server" id="Locations" datasourceid="LocationsDatasource"
   datatextfield="CountryName" datavaluefield="CountryCode" />

我想使用Javascript遍历客户端上的复选框元素并获取每个选中复选框的值,但这些值似乎在客户端不可用. HTML输出如下所示：

<table id="ctl00_Content_Locations" class="SearchFilterCheckBoxlist" cellspacing="0" cellpadding="0" border="0" style="width:235px;border-collapse:collapse;">
<tr>
    <td><input id="ctl00_Content_Locations_0" type="checkBox" name="ctl00$Content$Locations$0" /><label for="ctl00_Content_Locations_0">Democratic Republic of the Congo</label></td>
</tr><tr>
    <td><input id="ctl00_Content_Locations_1" type="checkBox" name="ctl00$Content$Locations$1" /><label for="ctl00_Content_Locations_1">Central African Republic</label></td>
</tr><tr>
    <td><input id="ctl00_Content_Locations_2" type="checkBox" name="ctl00$Content$Locations$2" /><label for="ctl00_Content_Locations_2">Congo</label></td>
</tr><tr>
    <td><input id="ctl00_Content_Locations_3" type="checkBox" name="ctl00$Content$Locations$3" /><label for="ctl00_Content_Locations_3">Cameroon</label></td>
</tr><tr>
    <td><input id="ctl00_Content_Locations_4" type="checkBox" name="ctl00$Content$Locations$4" /><label for="ctl00_Content_Locations_4">Gabon</label></td>
</tr><tr>
    <td><input id="ctl00_Content_Locations_5" type="checkBox" name="ctl00$Content$Locations$5" /><label for="ctl00_Content_Locations_5">Equatorial Guinea</label></td>
</tr>

无法找到值(“cd”,“cg”,“ga”等).他们在哪？甚至可以在客户端访问它们,还是我需要使用转发器或其他东西自己构建这个复选框？
