我在 aspx 页面上有服务器端控件，如文本框、dropdownlsit 等，我的目标是在页面加载期间隐藏它们。

使用下面的代码，控件在页面加载期间被隐藏，但我注意到闪烁。所需的输出应消除此控制闪烁。任何帮助是极大的赞赏。

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')
    }
}

隐藏服务器上的所有控件，在需要时在客户端显示它们，这样就不会出现显示一段时间后隐藏控件的问题

在 HTML 中

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

或在代码后面

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

并在需要时用 javascript 显示它们

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
    // .........
}
