在PageLoad中使用javascript處理頁面控件

Question

我在aspx頁面上有像textbox，dropdownlsit等服務器端控件，我的目標是在頁面加載期間隱藏它們。

使用下面的代碼，控件在頁面加載期間被隱藏，但我注意到閃爍。所需的輸出應該消除這種控制閃爍。任何幫助是極大的讚賞。需要這樣你就不必帶出，同時

在HTML後隱藏控件的問題時

var ispostBack =false; 
function pageLoad() { 
    $(document).ready(function() { 
     HideCtrls(); 
//Some other code here 
    } 

function HideCtrls() 
{ 
    document.getElementById("cph1_divSear").style.setAttribute('display', '') 
    if (document.getElementById("cph1_txtSearch")) 
    { 
     document.getElementById("cph1_txtSearch").style.setAttribute('display', 'none') 
     document.getElementById("cph1_txtkey").style.setAttribute('display', 'none') 
     document.getElementById("cph1_hypProjNo").style.setAttribute('display', 'none') 
     document.getElementById("cph1_ddlSeaSingle").style.setAttribute('display', 'none') 
     document.getElementById("cph1_txtSeaStart").style.setAttribute('display', 'none') 
     document.getElementById("cph1_txtSeaEnd").style.setAttribute('display', 'none') 
     document.getElementById("cph1_txtSeFLike").style.setAttribute('display', 'none') 
     document.getElementById("cph1_imgSeaSt").style.setAttribute('display', 'none') 
     document.getElementById("cph1_txtSeTLike").style.setAttribute('display', 'none') 
     document.getElementById("cph1_imgSeaEnd").style.setAttribute('display', 'none') 
     document.getElementById("cph1_txtPersonnel3").style.setAttribute('display', 'none') 
     document.getElementById("cph1_ImageButton3").style.setAttribute('display', 'none') 
     document.getElementById("likeFID").style.setAttribute('display', 'none') 
     document.getElementById("likeTID").style.setAttribute('display', 'none') 
     document.getElementById("dtFID").style.setAttribute('display', 'none') 
     document.getElementById("dtTID").style.setAttribute('display', 'none') 
    } 
} 

<div id="divSear" runat="server" class="cols4Search"> 
          <span> 
           <asp:TextBox ID="txtSearch" runat="server" Width="350px"></asp:TextBox>

          <asp:Label ID="lblNote" Visible="false" CssClass="Notelabel" runat="server" /> 
         </div> 

Answer 1

隱藏所有的服務器控件，它們顯示在客戶端

<asp:TextBox ID="txtSearch" style="display:none" Visible="False" Width="350px"></asp:TextBox> 

或在代碼後面

txtSearch.Attributes.Add("style", "display:none"); = "false"; 

並在需要時在JavaScript中顯示它們

if (document.getElementById("cph1_txtSearch")) 
{ 
    document.getElementById("cph1_txtSearch").style.setAttribute('display', 'block') 
    //Similarly you can show all field which are required to be shown 
    // ......... 
}
