<p>Create a hidden input with the name "chkNGI". 
Rename your current checkbox to something different.
Add handled for onClick on the checkbox and using a small javascript function, depending on the state of the checkbox, write 0 or 1 in the hidden input.</p>

<p>As an example,</p>

<pre><code>&lt;script&gt; 
    function calcParam() { 
        var checked = document.getElementById("prod_ngi_sn").checked;

        else 
            document.getElementById("hiddenNGI").value = "0"; 
    }

blocks|key|4556966|text|我知道这个问题很老了，但我最近不得不用Classic+ASP为一家公司重构一些遗留代码，结果遇到了这个问题。现有代码使用了与复选框同名的隐藏表单域，并在结果中查找"false“或"false，true”。这感觉有点笨拙，但代码也执行了基于带有前缀的动态命名复选框字段的操作，因此从缺少的字段推断"false“将引入不同的复杂性。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4556967|如果您希望复选框返回"0“或"1"，此技术应该可以做到这一点。它使用未命名复选框来操作已命名的隐藏字段。|4556968|<html>

<p>I know this question is old, but I recently had to refactor some legacy code for a company in Classic ASP, and ran into this problem.  The existing code used a hidden form field with the same name as the checkbox and looked for either "false" or "false, true" in the results.  It felt kludgy, but the code also performed actions based on dynamically named checkbox fields with prefixes, so inferring "false" from a missing field would introduce different complications.</p>

<p>If you want a checkbox to return either "0" or "1", this technique should do the trick.  It uses an unnamed checkbox to manipulate a named hidden field.</p>

<pre><code>&lt;html&gt;
&lt;body&gt;
&lt;% If isempty(Request("example")) Then %&gt;
&lt;form&gt;
&lt;input type="hidden" name="example" value="0"&gt;
&lt;input type="checkbox" onclick="example.value=example.value=='1'?'0':'1'"&gt;
&lt;input type="submit" value="Go"&gt;
&lt;/form&gt;
&lt;% Else %&gt;
&lt;p&gt;example=&lt;%=Request("example")%&gt;&lt;/p&gt;
&lt;% End If %&gt;
&lt;/body&gt;
&lt;/html&gt;
</code></pre>
