JavaScript Scrolling Status Bar Message

This page implements a scrolling status bar message using JavaScript. Here's how to use it:

Here's the full script:


<SCRIPT LANGUAGE="JavaScript">
<!--
// Use the following three variables 
// to set up the message:
var msg = "Enter your status bar message here"
var delay = 50
var startPos = 100

// Don't touch these variables:
var timerID = null
var timerRunning = false
var pos = 0

// Crank it up!
StartScrolling()

function StartScrolling(){
    // Make sure the clock is stopped
    StopTheClock()

    // Pad the message with spaces to 
    // get the "start" position
    for (var i = 0; i < startPos; i++) msg = " " + msg

    // Off we go...
    DoTheScroll()
}

function StopTheClock(){
    if(timerRunning)
        clearTimeout(timerID)
    timerRunning = false
}

function DoTheScroll(){
    if (pos < msg.length)
        self.status = msg.substring(pos, msg.length);
    else
        pos=-1;
    ++pos
    timerRunning = true
    timerID = self.setTimeout("DoTheScroll()", delay)
}
