Question

I know that there is a difference between ff and ie regarding the attribute ‘class’.

I want to put in the global.js something like that:

function GetVarByBrowser()
{
  if (navigator.appName == 'Microsoft Internet Explorer')
  {
    var getClass= 'className';
  }
  else
  {
    var getClass= 'class';
  }

}

and in the page i added this:

ElementServer.setAttribute(GetVarByBrowser(), 'server');

how can i make it works?

Answer 1

No need for global variables. Have the function return the value instead:

function GetVarByBrowser()
{
  if (navigator.appName == 'Microsoft Internet Explorer')
  {
    return 'className';
  }
  else
  {
    return 'class';
  }

}

However, this is an imperfect method of browser detection for a number of reasons. Have you considered using a library like jQuery that takes care of quirks like this automatically? Or do you want to learn this yourself (which is perfectly fine and commendable)?
