想要让可视性与控制的客户端真的,不可见从服务器端 [英] Want to make the visibility true from client side of the control which made invisible from server side
问题描述
我有一个网页的文本框。其可视性设置为从服务器侧假。现在我想通过使用Java脚本,使它从客户端可见。 (任何回发或部分回发不能在这种情况下实现的。)
I have a text box in a page. Whose visibility is set false from the server side. Now I want to make it visible from client side by using java-script. (Any post back or partial post back can not be implemented in this case.)
<%@ Page Title="Home Page" Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head id="Head1" runat="server">
<title>ControlVisibilityClientSide</title>
<script type="text/javascript">
function toggleVisibility(controlId)
{
var control = document.getElementById(controlId);
if(control.style.visibility == "visible" || control.style.visibility == "")
control.style.visibility = "hidden";
else
control.style.visibility = "visible";
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<input type="button" ID="btnShowHide" value="Show/Hide" onclick="toggleVisibility('TextBox1');" />
</div>
</form>
</body>
</html>
这是工作的罚款。
但是当我使用
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
TextBox1.Visible = false;
}
}
以上code是不工作的。
The above code is not working at all.
任何一个可以请帮我从这个问题或任何建议将AP preciated。
Can any one please help me out from this problem or any suggestion will be appreciated.
推荐答案
如果您设置控制的visible = false
也不会在客户端渲染,但是有一个棘手的解决方案,这将完成同样的事情。
If you set the control visible=false
it will not render at client side, But there is a tricky solution, that will accomplish the same thing.
在你的页面加载,你在哪里设置可见=假
,您可以在风格
设置为显示:无
In your page load, where you are set Visible=false
, you can set the style
to display:none
protected void Page_Load(object sender, EventArgs e)
{
TextBox1.Attributes.Add("style", "display:none");
}
这将使在客户端的控制,但用户看不到,然后你可以在看到JavaScript函数控制设置风格Diplay:块
,等等。 ..
document.getElementById('<%=TextBox2.ClientID %>').style.display = 'block';
