Cool Typing Effect, Eraser Effect and a Blinking Cursor using jQuery

These days I am tying to play with .animate() function of jQuery. Believe me, this function has been gifted with immense powers. While browsing the web, I found an interesring text effect using jQuery, written on Burnmind. This effect will catch your eyes, I bet. And thanks to Burnmind for providing such a cool tutorial.

jQuery Code

var captionLength = 0;
var caption = "";

$(document).ready(function()
{
  setInterval ( "cursorAnimation()", 600 );
});

function testTypingEffect()
{
  caption = $("input#userCaption").val();
  type();
}

function type() 
{
 $('p.caption').html(caption.substr(0, captionLength++));
 if(captionLength < caption.length+1)
 {
  setTimeout("type()", 50);
 }
 else
 {
  captionLength = 0;
  caption = "";
 } 
}

function testErasingEffect()
{
  caption = $("p.caption").html();
  captionLength = caption.length;
  if (captionLength>0)
  {
    erase();
  }
  else
  {
    $('p.caption').html("You didn't write anything to erase, but ok!");
    setTimeout("testErasingEffect()", 1000);
  }
}

function erase()
{
 $('p.caption').html(caption.substr(0, captionLength--));
 if(captionLength >= 0)
 {
  setTimeout("erase()", 50);
 }
 else {
  captionLength = 0;
  caption = "";
 } 
}

function cursorAnimation() 
{
  $("p.cursor").animate(
  {
    opacity: 0
  }, "fast", "swing").animate(
  {
    opacity: 1
  }, "fast", "swing");
}
