I need value to be passing from ASP.NET page to JavaScript and then to HTML textfield.

My following code is able to read values from ASP.NET to JavaScript but unable to pass value form JavaScript to HTML TextField. Can anybody please correct my code.

Default.aspx

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

<head id="Head1" runat="server">
    <title></title>
    <script type="text/javascript">
        function can() {
            var myVariable = '<%=ServerSideVariable %>';
            document.write(myVariable);
        }
</script>
</head>
<body>
    <form id="form1" runat="server">
    <div>

        <br />
        <br />
        <br />
        <br />
        <br />
        <input id="Text1" type="text" value='can()'/>
    </div>
    </form>
</body>
</html>

Default.aspx.cs

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
{
    public string ServerSideVariable { get; set; }

    protected void Page_Load(object sender, EventArgs e)
    {
        string pval = "Passed value;
        ServerSideVariable = pval;
    }

}

    As others have said with javascript OR like this:

    (since there is nothing in your example that requires javascript — KISS— don’t use javascript if you don’t have to do so.)

    <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

<head id="Head1" runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>

        <br />
        <br />
        <br />
        <br />
        <br />
        <input id="Text1" type="text" ><%=ServerSideVariable %></input>
    </div>
    </form>
</body>
</html>
