Reading a AppKey value from web.config in clientside js RRS feed

  • Question

  • User396067491 posted


    I don't know why this isn't working, everything I've read says it should.  I have created a appkey variable in the web.config file and i'm now trying to read it in an aspx page within a javascript variable.

    The setup is below:


    <appSettings file="">
    <add key="webAccount" value="12345678" />

    My javascript variable in the aspx page:

    <script type="text/javascript">
        var setWebAccountNumber = '<%=ConfigurationSettings.AppSettings["webAccount"].ToString() %>';

    The error I get is shown below:

    Compilation Error

    Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

    Line 35: <script type="text/javascript">
    Line 36: var setWebAccountNumber = '<%=ConfigurationSettings.AppSettings["webAccount"].ToString() %>';

    Hi, there is no error with your codes, I tested on my computer and found they worked. I suggest commenting the error line and try to print


    with behind codes to check whether the value can be got properly.


    <!DOCTYPE html>
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head runat="server">
        <script type="text/javascript">
            //var setWebAccountNumber = '<%=ConfigurationSettings.AppSettings["webAccount"].ToString() %>';
        <form id="form1" runat="server">


    protected void Page_Load(object sender, EventArgs e)
                string val = ConfigurationSettings.AppSettings["webAccount"].ToString();

    thanks for the responses.

    I did was you suggestioned (I can't believe I never thought of that) and tested the values from the code behind.  It works fine.  I just seems that the errors are thrown when I put the same code values in the javascript of the header.   I can't figure out why, it should work.
