        //Session Warning

Seems to be wrong string assignment. try this

var sessionTimeoutWarning = '<%= System.Configuration.ConfigurationSettings.AppSettings["SessionWarning"].ToString()%>';

use single quotes ( ' ) not ( " )

var sessionTimeoutWarning = "<%= System.Configuration.ConfigurationSettings.AppSettings["SessionWarning"].ToString()%>";

Hi，

In fact I think you can just use single quote sample，sample like this：

var sessionTimeoutWarning = '<%= System.Configuration.ConfigurationSettings.AppSettings["SessionWarning"]%>';

hi dotnetramesh you give me a broken link,,, please check it

Answer 9

User-663458986 posted

in your provided link, it says 

"sessionTimeoutWarning: is a predefined value in the application configuration. Say 18 minutes."

which means you need to add a Setting key in your Web.Config file.

<appSettings>
    <add key ="SessionWarning" value ="1"/>
  </appSettings> 

if you already have AppSettings in your config file, than only add 

<add key ="SessionWarning" value ="1"/>

Hai

Check your webconfig and  your code from vijay_myl ways

 

<configuration>

      <appSettings>

            <add key="var1"value="SomeValue"/>

      </appSettings>

      <connectionStrings>

<add name="MyConnString"connectionString="Data   Source=(local);Initial Catalog=Northwind;Integrated Security=True;"/>

      </connectionStrings>

...

<configuration>

 

To read these entries using javascript, use the below:

    <script type="text/javascript">

    function ReadConfigSettings()

    {

  var conn='<%=ConfigurationManager.ConnectionStrings["MyConnString"].ConnectionString %>'

        alert(conn);

        var v1 = '<%=ConfigurationManager.AppSettings["var1"].ToString() %>'

        alert(v1);

    }

    </script>

 

 To read these entries using JavaScript , use the below:
