html - Jquery input validation dependent on checkbox value -


i trying avoid validation mess , using inline validation. have checkbox followed 3 input boxes. if checkbox checked, input fields have become "required". else not.

here code:

<div class="col-xs-12">      <div class="form-group">          <label class="checkbox-inline">          <input type="checkbox" id="vi" name="vi" checked="checked">              have apple          </label>      </div>  </div>    <div class="col-xs-6">      <div class="form-group">          <label>apple condition?</label>           <input type="input" class="form-control" id="applecond" validate="required:'checkbox[name=vi][value=yes]:checked'">      </div>  </div>    <div class="col-xs-6">      <div class="form-group">          <label>sourced ?</label>           <input type="input" class="form-control" id="applesource" validate="required:'checkbox[name=vi][value=yes]:checked'">      </div>  </div>    <div class="col-xs-6">      <div class="form-group">          <label>quantity</label>           <input type="input" class="form-control" id="applequantity" validate="required:'checkbox[name=vi][value=yes]:checked'">      </div>  </div>  </div>

i sure doing wrong syntax. can point correct syntax?

well can done follows. default make checkbox unchecked , write following jquery it

    $(document).ready(function(){       var atleastoneischecked = $('input[name="vi"]:checked').length > 0;        if(atleastoneischecked){         $("input").attr("required", "true");       }     else {         // else need case     } });
