Prevent the display of cascading div elements by using JavaScript and jQuery scripting

My webpage performs a simple check to verify if Javascript and cookies are enabled on the client's browser. If they are enabled, the script displays the content inside div id="conteudo" and hides the warning message inside div id="aviso". If not, the script keeps the warning visible and hides the content.

Everything works perfectly on my offline project, but on the server, the page seems to load a bit slow. When certain conditions of the script occur (such as Javascript or cookies being disabled), I can see the warning message inside div id="aviso" for a fraction of a second before it disappears. This is not the experience I had planned. Does anyone know how I can fix this issue in my code? Thank you.


var JS_Enabled = false;
var C_Enabled = false;

$(document).ready(function()
{
  //Test for JavaScript (if entered here, it's enabled).
  JS_Enabled = true;
  //Test for cookies.
  var TEST_COOKIE = 'test_cookie';
  $.cookie(TEST_COOKIE, true);
  if ($.cookie(TEST_COOKIE))
  {
    $.cookie(TEST_COOKIE, null); //delete the cookie.
    C_Enabled = true;
  }
  //Final evaluation.
  if (JS_Enabled && C_Enabled)
  {
    $("#aviso").hide();
    $("#conteudo").show();
  }
  else
  {
    $("#aviso").show(); 
    $("#conteudo").hide();
  }
});

Answer №1

Once you have added JQuery, you can easily hide your elements by following this code snippet:

 $(document).ready(function(){
     $("#warning").hide(); 
     $("#content").hide();
 });

You can also achieve the same effect using CSS:

#warning,#content{display:none}
