  Detecting if scripting is on/off in browser

  Mar 01, 2012 04:59 PM|LINK

  Yes yes, I know, loads of samples out there...

  Here's one I cannot find.

  Detect if javascripting is enabled/disabled WITHOUT adding a parameter or a redirect to the current url.

  All samples I have found, append a flag of some sort according the scripting being on or off. like  mypage.aspx?jscript=1

  I don't want that at all.
  
  I want to check for js, write a flag to a session var and I'm guessing a client side script needs to do that via RegisterStartupScript.
  If session["jsenabled"] != null, the script must have written that session var else script must be disabled...

  no?

  no flags appended to the end of the url, none.

   

  :-)

  Dear friend,

  Consider the follwoing

  - There is no server side code makes you know the script is enabled or not in the client browser.

  - If you detect that using flag that will be set using client side and check it in the server, there is a work around telling that user may disable or enable javascript in any time, as a result it is useless to save the javascript client status.

  Finally, make your validations and client side code and do not forget to make the server side validation before executing any business logic.

  set a hidden field with JavaScript. When the page is posted back, you can check that hidden field. If set, you know it is enabled.

  Hi,

  Try this code:

  function hideScriptDisabled() {
    document.getElementById("scriptDisabled").display = "none";
  }
  
  
  <p id="scriptDisabled">You have JavaScript disabled, <a href="#">click here</a>.</p>
  <script type="text/javascript">hideScriptDisabled();</script>
