Question

with this jquery, I am trying to delete the css class but it is not doing that one.

   $(".validate_txt_sContactPhone.error").next().removeClass("atleastTwoChars");

  <nobr><input name="ctl00$objContentPageTag$spzContactInformation$txt_sContactPhone$txt" type="text" size="25" id="ctl00_objContentPageTag_spzContactInformation_txt_sContactPhone_txt" class="xqh_TextBox_Edit validate_txt_sContactPhone error">
  <div class="atleastTwoChars"></div>
   <label for="ctl00_objContentPageTag_spzContactInformation_txt_sContactPhone_txt" generated="true" class="error">2*</label></nobr>

Works fine here:

My guess would be that the $(".validate_txt_sContactPhone.error") selector is grabbing the wrong element from somewhere else on the page.
