在哪里存放了的CheckBoxList的DataValueField值？ [英] Where are the DataValueField values for a CheckBoxList stored?

问题描述

我有一个网页上这样的CheckBoxList：

I have this CheckBoxList on a page:

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

我想通过使用Javascript在客户端上的复选框元素循环和各抢选中的复选框的值，但这些值不会出现可用在客户端上。 HTML输出如下：

I'd like to loop through the checkbox elements on the client using Javascript and grab the value of each checked checkbox, but the values don't appear to be available on the client side. The HTML output looks like this:

<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>

（CD，CG，嘎等）都无处值被发现。他们在哪？它甚至有可能访问它们的客户端，或者是否需要建立这个使用中继器或东西的CheckBoxList自己？

The values ("cd", "cg", "ga", etc.) are nowhere to be found. Where are they? Is it even possible to access them on the client, or do I need to build this checkboxlist myself using a repeater or something?

推荐答案

在ViewState中存储，则无法在客户端上访问它们没有的 一些黑客 。

Stored in ViewState, you cannot access them on the client without some hacking.
