hi, can anyone help to explain this code.. or is their an equivalent vbscript for this code? please help...don't know about javascript.. thanks in advance..

if(arguments.length == 3){
  var result = "<" + arguments[1] + ">";
  for (var i = 0; i < arguments[2].length; i++){
   result += "<li>" + arguments[2][i] + "</li>";
  }
  result += "</" + arguments[1] + "l>";
  document.getElementById(arguments[0]).innerHTML = result;
 }
}
if(arguments.length == 3){
  var result = "<" + arguments[1] + ">";
  for (var i = 0; i < arguments[2].length; i++){
   result += "<li>" + arguments[2][i] + "</li>";
  }
  result += "</" + arguments[1] + "l>";
  document.getElementById(arguments[0]).innerHTML = result;
 }
}

It looks like this is creating an unordered list. arguments must be an array that contains an HTML element id name in arguments[0], an HTML tag name in arguments[1], and a list item label in arguments[2].

The part of the code if(arguments.length == 3) says that there should only be 3 elements in the array, arguments[0], [1], and [2].

I'll provide some example definitions for the variables to show you how it works.

var arguments = new Array("menu", "ul");
arguments[2] = new Array("List item 1", "List item 2", "List item 3");

if(arguments.length == 3){
  var result = "<" + arguments[1] + ">";
  for (var i = 0; i < arguments[2].length; i++){
   result += "<li>" + arguments[2][i] + "</li>";
  }
  result += "</" + arguments[1] + ">";
  document.getElementById(arguments[0]).innerHTML = result;
 }
}

will produce:

<ul>
	<li>List item 1</li>
	<li>List item 2</li>
	<li>List item 3</li>
</ul>

and put the result into the element in the HTML labeled "menu".


If you want to see this in action, copy the script on this page and paste it into Tryit editor.

You can also try this code. This demo will automatically inject vbscript in your document, if it detects IE browser's and the code output is also converted into vbscript:
