  View page does not recognize null element in load

  Nov 17, 2012 10:51 AM|LINK

  I have an javascript function that generate links in my page based on DropDown. I checked the javascript function in two moments, when the dropDown change, with atribute "onchange", and when the page is load. The error is generating when page is load without element on viewbag, my javascript is not recognizes the null element for generate links without the information on viewbag.

  <p>Pesquisar por: @Html.DropDownList("tipoPesquisa", ViewBag.DropDownPesquisa as SelectList, new { onchange = "alteraFiltro()" })
  
  
  
  <div id="dadosFornecedor">
          @if (ViewBag.CurrentFornecedor != null)
          {
              <fieldset>
                  <legend>@ViewBag.CurrentFornecedor.RazaoSocial</legend>
                  <b>Razão Social:</b> @ViewBag.CurrentFornecedor.RazaoSocial <b>Endereço:</b> @ViewBag.CurrentFornecedor.Endereco
                  @Html.Hidden("idFornecedor", new { IdFornecedor = ViewBag.CurrentFornecedor.IdFornecedor })
                  <input type="button" class="btn" onclick="removerFornecedor();" value="Remover Fornecedor" />
                  <br />
                  <br />
              </fieldset>
              <br />
  
          }
      </div>
  
  
  <script type="text/javascript">
      $(function () {
  
         alteraFiltro();
      });
  
      function removerFornecedor() {
          var div = $("#dadosFornecedor");
          var hidden = $("#idFornecedor");
          div.empty();
  
          div.append("<input type='hidden' name='deletarFornecedor' value='true' />")
  
      }
  
          function alteraFiltro() {
              var urlCodigo = $("#linkCodigo");
              var urlLancamento = $("#linkLancamento");
              var urlPagamento = $("#linkPagamento");
              var urlFornecedor = $("#linkFornecedor")
              var dropValue = $("#tipoPesquisa").val();
              var hidden = $("#idFornecedor");
  
              if (hidden.val() == "" || hidden.val() == null || hidden == null) {
                  urlCodigo.attr("href", "saidasDiversas?sortOrder=@ViewBag.CodigoSortParm&currentFilter=@ViewBag.CurrentFilter&currentDrop=" + dropValue + "");
                  urlLancamento.attr("href", "saidasDiversas?sortOrder=@ViewBag.DataLancamentoSortParm&currentFilter=@ViewBag.CurrentFilter&currentDrop=" + dropValue + "");
                  urlPagamento.attr("href", "saidasDiversas?sortOrder=@ViewBag.DataPagamentoSortParm&currentFilter=@ViewBag.CurrentFilter&currentDrop=" + dropValue + "");
                  urlFornecedor.attr("href", "saidasDiversas?sortOrder=@ViewBag.FornecedorSortParm&currentFilter=@ViewBag.CurrentFilter&currentDrop=" + dropValue + "")
              } else{
                  urlCodigo.attr("href", "saidasDiversas?sortOrder=@ViewBag.CodigoSortParm&idFornecedor=@ViewBag.CurrentFornecedor.IdFornecedor&currentFilter=@ViewBag.CurrentFilter&currentDrop=" + dropValue + "");
                  urlLancamento.attr("href", "saidasDiversas?sortOrder=@ViewBag.DataLancamentoSortParm&idFornecedor=@ViewBag.CurrentFornecedor.IdFornecedor&currentFilter=@ViewBag.CurrentFilter&currentDrop=" + dropValue + "");
                  urlPagamento.attr("href", "saidasDiversas?sortOrder=@ViewBag.DataPagamentoSortParm&idFornecedor=@ViewBag.CurrentFornecedor.IdFornecedor&currentFilter=@ViewBag.CurrentFilter&currentDrop=" + dropValue + "");
                  urlFornecedor.attr("href", "saidasDiversas?sortOrder=@ViewBag.FornecedorSortParm&idFornecedor=@ViewBag.CurrentFornecedor.IdFornecedor&currentFilter=@ViewBag.CurrentFilter&currentDrop=" + dropValue + "")
              }
  
          }
  
  
      </script>
