.NET判断日期为空：

if (rec.PENDING_END_DATE == null || rec.PENDING_END_DATE.Equals(DateTime.MinValue))

 

1、

DateTime deadline = Convert.ToDateTime(deadlineStr);
            return deadline.ToString("yyyy-MM-dd HH:mm:ss");

string now = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss");

 2、

object obj = tmp;
     if (obj is DateTime)
     {
           DateTime time = (DateTime)obj;
           td.Text = time.ToString("yyyy-MM-dd HH:mm:ss");
      }
      else {
            td.Text = obj.ToString();
      }

   function createNameSpan(name, value) {
        var handleDiv = document.getElementById("handle_users");
        var span = document.createElement("span");
        span.setAttribute("value", value);
        span.innerHTML = name;
        var del = document.createElement("img");
        del.src = "../../AspUC/UCFileUpLoad/images/f2.gif";
        del.className = "";

        del.onclick = function() {
            var name = this.parentNode.attributes["value"].value;
            remove(name);
            handleDiv.removeChild(this.parentNode);
        }

        span.appendChild(del);
        return span;

    }

4、隐藏展示表格行可通过tbody这种方式实现，不用在每行上加

<tr>
	<th>产品账号：</th>
	<td>
	   <asp:TextBox ID="FV_7" runat="server" ></asp:TextBox>                                       
	</td>
    <th>产品名称：</th>
	<td>
		<asp:DropDownList ID="FV_8" runat="server"></asp:DropDownList>                                        
	</td>                         
</tr>

<tbody id="tb_search" style="display: none; border: 0px;">
<tr> 
	<th>使用状态：</th>
	<td style="text-align:left;">
		<asp:DropDownList ID="USE_STATUS" runat="server"></asp:DropDownList>     
	</td>   
	<th>上线时间从</th>
	<td>
		<asp:TextBox ID="OnLineStartDate" runat="server" onfocus="WdatePicker({dateFmt:'yyyy-MM-dd'})"
			class="Wdate" Width="90px" Height="19px"></asp:TextBox>
		到
		<asp:TextBox ID="OnLineEndDate" runat="server" onfocus="WdatePicker({dateFmt:'yyyy-MM-dd'})"
			class="Wdate" Width="90px" Height="19px"></asp:TextBox>
	</td>
</tr>
</tbody>
