<script>
var someSession = '<%= Session["SessionName"].ToString() %>';
alert(someSession)
</script>
This code you can write in Aspx. If you want this in some js.file, you have two ways:
这段代码可以用 Aspx 编写。如果你想在一些 js.file 中使用它，你有两种方法：
- Make aspx file which writes complete JS code, and set source of this file as Script src
- Make handler, to process JS file as aspx.
- 制作编写完整JS代码的aspx文件，并将该文件的源设置为Script src
- 制作处理程序，将 JS 文件处理为 aspx。

You can access your session variable like '<%= Session["VariableName"]%>'
您可以访问您的会话变量，如 '<%= Session["VariableName"]%>'
the text in single quotes will give session value. 1)
单引号中的文本将给出会话值。1)
<script>
var session ='<%= Session["VariableName"]%>'
</script>
2) you can take a hidden field and assign value at server;
2）您可以在服务器上取一个隐藏字段并赋值；
hiddenfield.value= session["xyz"].tostring();
hiddenfield.value= session["xyz"].tostring();
//and in script you access the hiddenfield like
alert(document.getElementbyId("hiddenfield").value);

protected void Page_Load(object sender, EventArgs e)
{
Session["MyTest"] = "abcd";
String csname = "OnSubmitScript";
Type cstype = this.GetType();
// Get a ClientScriptManager reference from the Page class.
ClientScriptManager cs = Page.ClientScript;
// Check to see if the OnSubmit statement is already registered.
if (!cs.IsOnSubmitStatementRegistered(cstype, csname))
{
string cstext = " document.getElementById(\"TextBox1\").value = getMyvalSession() ; ";
cs.RegisterOnSubmitStatement(cstype, csname, cstext);
}

If you are using VB as code behind, you have to use bracket "()" instead of square bracket "[]".
如果您使用 VB 作为代码隐藏，则必须使用方括号“()”而不是方括号“[]”。
Example for VB:
VB 示例：
<script type="text/javascript">
var accesslevel = '<%= Session("accesslevel").ToString().ToLower() %>';
</script>
