  1. POWebform checkbox value in javascript
    text
    copied!<p>I have a checkbox list control on my asp.net web form that I am dynamically populating from an arraylist. In javascript I want to be able to iterate through the values in the list and if a particular value has been selected to display other controls on the page. </p> <p>My issue is that all the values in the checkbox list are showing up as 'on' instead of the actual value set. How do I get the actual values for each checkbox?</p> <p>Thanks.</p> <p>Javascript:</p> <pre><code>checkBoxs=document.getElementById(CheckboxList); var options=checkBoxs.getElementsByTagName('input'); for(var i=0;i&lt;options.length;i++) { if(options[i].value=="Other") { if(options[i].checked) { var otherPub=document.getElementById('&lt;%=alsOtherPublicity.ClientID%&gt;'); otherPub.style.display='block'; } } } </code></pre> <p><strong>Edit:</strong> The line that I'm having problems with is if(options[i].value=="Other") as the values showing up in firebug are given as 'on' rather than the values that I set.</p> <p><strong>Edit 2:</strong> The html that is produces looks like:</p> <pre><code>&lt;span id="ctl00_ContentPlaceHolderMetadata_Allocation1_alfPublicity" class="ucFieldCBL" onChange="alValidate();" onClick="alPublicity('ctl00_ContentPlaceHolderMetadata_Allocation1_alfPublicity');"&gt; &lt;input id="ctl00_ContentPlaceHolderMetadata_Allocation1_alfPublicity_0" type="checkbox" name="ctl00$ContentPlaceHolderMetadata$Allocation1$alfPublicity$0"/&gt; &lt;label for="ctl00_ContentPlaceHolderMetadata_Allocation1_alfPublicity_0"&gt;Text1&lt;/label&gt; &lt;input id="ctl00_ContentPlaceHolderMetadata_Allocation1_alfPublicity_1" type="checkbox" name="ctl00$ContentPlaceHolderMetadata$Allocation1$alfPublicity$1"/&gt; &lt;label for="ctl00_ContentPlaceHolderMetadata_Allocation1_alfPublicity_1"&gt;Text2&lt;/label&gt; &lt;input id="ctl00_ContentPlaceHolderMetadata_Allocation1_alfPublicity_2" type="checkbox" name="ctl00$ContentPlaceHolderMetadata$Allocation1$alfPublicity$2"/&gt; &lt;label for="ctl00_ContentPlaceHolderMetadata_Allocation1_alfPublicity_2"&gt;Text3&lt;/label&gt; &lt;input id="ctl00_ContentPlaceHolderMetadata_Allocation1_alfPublicity_3" type="checkbox" name="ctl00$ContentPlaceHolderMetadata$Allocation1$alfPublicity$3"/&gt; &lt;label for="ctl00_ContentPlaceHolderMetadata_Allocation1_alfPublicity_3"&gt;Text4&lt;/label&gt; &lt;input id="ctl00_ContentPlaceHolderMetadata_Allocation1_alfPublicity_4" type="checkbox" name="ctl00$ContentPlaceHolderMetadata$Allocation1$alfPublicity$4"/&gt; &lt;label for="ctl00_ContentPlaceHolderMetadata_Allocation1_alfPublicity_4"&gt;Text5&lt;/label&gt; &lt;/span&gt; </code></pre> <p>It looks as if the issue stems from the lack of a value attribute available on the asp.net checkbox control as described by <a href="http://www.daveparslow.com/2007/08/assigning-value-to-aspnet-checkbox.html" rel="nofollow noreferrer" title="Dave Parslow">Dave Parslow</a>. I'm currently trying a workaround by calling a function server side to return the text of the checkbox and using that instead. </p>
