    copied!<p>The value of previousDiv when i run the jQuery shown below is always: [ ]. I have tried several variations of the .prev() function including .prev('div'), and .prev() all with the same result.</p> <p>Here is the jQuery:</p> <pre><code>$('.AddToRole').click(function(evt) { var path = document.URL; var thisUser = this.value; var previousControl = $(this).prev('.AvailableRoles'); var newUserRole = previousControl[0].options[previousControl[0].selectedIndex].text; var newHTML = "&lt;button id='button_DeleteRole_" + newUserRole +"' class='DeleteRole' value=" + newUserRole + "&gt;X&lt;/button&gt;&amp;nbsp;&lt;label id='label_DeleteRole_" + newUserRole + "'&gt;" + newUserRole + "&lt;/label&gt;&lt;br /&gt;"; var previousDiv = $(this).prev('#DisplayUserRoles'); $(previousDiv).append(newHTML); </code></pre> <p>Here is the html/razor code in the page:</p> <pre><code>&lt;div&gt; @* Display user email. *@ &lt;h3&gt;@user.Email&lt;/h3&gt; &lt;div&gt; &lt;div id="DisplayUserRoles"&gt; @{ @* Display roles user belongs to. *@ foreach (var role in userRoles) { @* Remove user from role button. *@ &lt;button id="button_RemoveFromRole_@user.Email" value="@role.RoleName" onclick="RemoveUserFromRole(this);"&gt;X&lt;/button&gt; &lt;label id="label_RemoveFromRole_@role.RoleName"&gt;@role.RoleName&lt;/label&gt; &lt;br /&gt; } } &lt;/div&gt; &lt;br /&gt; @{ @* Create ListBox with roles user does not belong to. *@ var items = rolesUserDoesNotBelongTo.Select(i =&gt; new SelectListItem { Value = i.RoleName, Text = i.RoleName }); string listBoxId = "listboxRoles_"; listBoxId = listBoxId + user.Email; } @Html.ListBox(listBoxId, items, new { @class = "AvailableRoles" }) @* Add user to role button. *@ &lt;button id="button_AddToRole_@user.Email" class="AddToRole" value="@user.Email"&gt;Add To Role&lt;/button&gt; &lt;/div&gt; &lt;/div&gt; </code></pre> <p>For the end result I am trying to add another button and label just before the closing div tag for #DisplayUserRoles.</p>
