I am helping a friend maintain his web site that was generated in Dreamweaver. I am supporting using HTML and Javascript and need to replace the animated text that was probably Flash generated because the background color is changing. I am a beginner Javascript coder so would like some help getting this done.
The link below contains the animated text of "Charles T. Cozens" that I want to duplicate directly in Javascript.

function animateStr(strIn, oDest) {
outPut=document.getElementById(oDest);
outPut.innerHTML = "";
var i = 0;
animChar = setInterval("nextChar()",500);
nextChar = function () {
outPut.innerHTML += strIn.charAt(i);
i++;
if (i > strIn.length) clearInterval(animChar);
}
}
window.onload = function () {
animateStr("Hello from TheBear", "oPut");
}
</script></head><body><div id="oPut"></div></body></html>
Thanks TheBearMay. I appreciate the start. I now need to loop through each character in the string starting to the right of the final character position and a little below. Each character starts out small and increases in size until it reaches the final position. This is done for each character in the string. I will attempt this on my own but hints are always appreciated.

// Basic Element Animator (29-April-2009)
// by Vic Phillips http://www.vicsjavascripts.org.uk
// To progressively change the Left, Top, Width, Height or Opacity of an element over a specified period of time.
// With the ability to scale the effect time on secified minimum/maximum values
// and with three types of progression 'sin' and 'cos' and liner.
// **** Application Notes
// **** The HTML Code
//
// when moving an element the inline or class rule style position of the element should be assigned as
// 'position:relative;' or 'position:absolute;'.
//
// The element would normally be assigned a unique ID name.
//
// **** Executing the Effect(Script)
//
// The effect is executed by an event call to function 'zxcBAnimator('width#',document.getElementById('tst'),10,800,5000,[10,800],'sin');'
// where:
// parameter 0 = the mode(see Note 2). (string)
// parameter 1 = the unique ID name or element object. (string or element object)
// parameter 2 = the start position of the effect. (digits, for opacity minimum 0, maximum 100)
// parameter 3 = the finish position of the effect. (digits, for opacity minimum 0, maximum 100)
// parameter 4 = (optional) period of time between the start and finish of the effect in milliseconds. (digits or defaults to 2000 milliSeconds)
// parameter 5 = (optional) to scale the effect time on a secified minimum/maximum. (array, see Note 5)
// field 0 the minimum. (digits)
// field 1 the maximum. (digits)
// parameter 6 = (optional) the type of progression, 'sin', 'cos' or 'liner'. (string, default = 'liner')
// 'sin' progression starts fast and ends slow.
// 'cos' progression starts slow and ends fast.
//
// Note 1: The default units(excepting opacity) are 'px'.
// Note 2: Examples modes: 'left', 'top', 'width', 'height', 'opacity.
// For hyphenated modes, the first character after the hyphen must be upper case, all others lower case.
// Note 3: To 'toggle' the effect include '#' in parameter 0.
// The first call will set the toggle parameters.
// Subsequent calls with '#' in parameter 0 and the same start and finish parameters will 'toggle' the effect.
// Note 4: The function may be re-executed with a different set of parameters (start/finish time or period)
// whenever required, say from an onclick/mouseover/out event.
// The period parameter will be retained unless re-specified.
// Note 5: parameter 5 is of particular use when re-calling the effect
// in mid travel to retain an constant rate of progression.
// Note 6: parameters 2 and 3 must be different values to initilise or execute the script.
//
// **** Advanced Applications
//
// Calling function 'zxcBAnimator' returns the instance of the script,
// this may be assigned to a variable and used to access the current value of the effect.
// alternativly the sript instance by elementobject[mode.replace(/\W/g,'')+'oop'];
// where mode is parameter 0 of the initial call.
// An array storing the current, start and finish values of the element effect may be accessed
// from the element effect.data as fields 0, 1 and 2 respectively
//
// **** General
//
// All variable, function etc. names are prefixed with 'zxc' to minimise conflicts with other JavaScripts.
// These characters may be changed to characters of choice using global find and replace.
//
// The Functional Code(about 2.15K) is best as an External JavaScript.
//
// Tested with IE7 and Mozilla FireFox on a PC.
//
// **** Functional Code - NO NEED to Change
