    Need Help with Registering Client Scripts

    I'm trying to duplicate an HTML sample I have using my ASP.NET pages.

    The sample contains the following within the <headtag:

    <script type="text/javascript" src="flashobjec t.js"></script>
    <script type="text/javascript">
    // <![CDATA[
    var args = new Object();
    var query = location.search .substring(1);
    // Get query string
    var pairs = query.split( "," );
    // Break at comma
    for ( var i = 0; i < pairs.length; i++ )
    {
    var pos = pairs[i].indexOf('=');
    if( pos == -1 )
    {
    continue; // Look for "name=value "
    }
    var argname = pairs[i].substring( 0, pos ); // If not found, skip
    var value = pairs[i].substring( pos + 1 ); // Extract the name
    args[argname] = unescape( value ); // Extract the value
    }
    // ]]>
    </script>

    To do this the ASP.NET way, I added the following code to my Page_Load
    handler:

    if (!Page.ClientSc ript.IsClientSc riptBlockRegist ered("FlashObje ct"))
    Page.ClientScri pt.RegisterClie ntScriptInclude (typeof(Page),
    "FlashObjec t", "flashobject.js ");

    if (!Page.ClientSc ript.IsStartupS criptRegistered ("PrepVideo" ))
    Page.ClientScri pt.RegisterStar tupScript(typeo f(Page), "PrepVideo" ,
    "var args=new Object();" +
    "var query=location. search.substrin g(1);" +
    "var pairs=query.spl it(',');" +
    "for (var i=0;i < pairs.length;i+ +){" +
    "var pos=pairs[i].indexOf('=');" +
    "if (pos==-1) continue;" +
    "var argname=pairs[i].substring(0,po s);" +
    "var value=pairs[i].substring(pos + 1);" +
    "args[argname]=unescape(value );}", true);
    }

    I assume the second script is a start-up script since it is not a callable
    function. So this seems like it should work but it does not duplicate the
    functionality of the sample.

    Looking at the HTML produced, I see neither registered scripts are placed
    within the <headtag. So instead of calling RegisterClientS criptInclude and
    RegisterStartup Script, I instead forced these scripts into the <headtag
    and they WORKED!!

    Unfortunately, I need to put this in a control that really should register
    the scripts in an organized way.

    Is there any way to register a script such that it is inserted within the
    <headtag? Or perhaps there's something else I'm missing?

    Thanks.

    Jonathan

      Hi

      use this method to check wheiter script already added or not...

      Page.ClientScri pt.IsClientScri ptBlockRegister ed();

      and to register use

      Page.ClientScri pt.RegisterClie ntScriptBlock() ;

      Best of luck

          Well, thanks. But not only does this not address the problem I've described,
          you're telling me to do exactly what the code I posted shows I was already
          doing.

              Hi Jonathan

              "RegisterStartu pScript" add scripts just before the end of "</body>"
              tag..
              and "RegisterClient ScriptBlock" add script inside the form as far as i
              seen so far..
              well since you need the script in the head block here is a work around
              i found and worked for me...

              i added a literal control in size the head tag

              <head id="Myhead" runat="server">
              <title>Untitl ed Page</title>
              <asp:Literal ID="ScriptSourc e" runat="server"> </asp:Literal>
              </head>

              and in page load event i did this

              ScriptSource.Te xt = "<script>window .alert('Worked okay');</script>";

              surely you need to do some coding to adjust what you want to insert in
              head...

              Best of luck

                  Re: Need Help with Registering Client Scripts

                  I figured this out. Turns out that it is not necessary for these scripts to
                  be within the <headtag. I don't understand exactly how they are used but
                  if I don't register the second script as a startup script and instead
                  register it as a regular client script block, it appears to work just fine.
                  Thanks.

                  To do this the ASP.NET way, I added the following code to my Page_Load
                  handler:
                  >>
                  if (!Page.ClientSc ript.IsClientSc riptBlockRegist ered("FlashObje ct"))
                  Page.ClientScri pt.RegisterClie ntScriptInclude (typeof(Page),
                  "FlashObjec t", "flashobject.js ");
                  >>
                  if (!Page.ClientSc ript.IsStartupS criptRegistered ("PrepVideo" ))
                  Page.ClientScri pt.RegisterStar tupScript(typeo f(Page), "PrepVideo" ,
                  "var args=new Object();" +
                  "var query=location. search.substrin g(1);" +
                  "var pairs=query.spl it(',');" +
                  "for (var i=0;i < pairs.length;i+ +){" +
                  "var pos=pairs[i].indexOf('=');" +
                  "if (pos==-1) continue;" +
                  "var argname=pairs[i].substring(0,po s);" +
                  "var value=pairs[i].substring(pos + 1);" +

                  I assume the second script is a start-up script since it is not a
                  callable
                  function. So this seems like it should work but it does not duplicate
                  the
                  functionality of the sample.
                  >>
                  Looking at the HTML produced, I see neither registered scripts are
                  placed
                  within the <headtag. So instead of calling
                  RegisterClientS criptInclude
                  and
                  RegisterStartup Script, I instead forced these scripts into the <head>
                  tag
                  and they WORKED!!
                  >>
                  Unfortunately, I need to put this in a control that really should
                  register
                  the scripts in an organized way.
                  >>
                  Is there any way to register a script such that it is inserted within
                  the
                  <headtag? Or perhaps there's something else I'm missing?

                  "RegisterStartu pScript" add scripts just before the end of "</body>"
                  tag..
                  and "RegisterClient ScriptBlock" add script inside the form as far as i
                  seen so far..
                  well since you need the script in the head block here is a work around
                  i found and worked for me...
                  >
                  i added a literal control in size the head tag
                  >
                  <head id="Myhead" runat="server">
                  <title>Untitl ed Page</title>
                  <asp:Literal ID="ScriptSourc e" runat="server"> </asp:Literal>
                  </head>
                  >
                  and in page load event i did this
                  >
                  ScriptSource.Te xt = "<script>window .alert('Worked okay');</script>";
                  >
                  surely you need to do some coding to adjust what you want to insert in
                  head...
