Introduction

This example requires :

PEAR::HTML_Progress 1.2.0RC3 or better.

This example will run a natural horizontal ProgressBar with blue skin. It will also show you how to print something inside cells with an external javascript (replaced internal code).

Percent text info is centered on a 60 pixels width area, on right side of the progress bar.

HTML_Progress_UI::setStringAttributes()

Here is the external javascript source-code which replace internal code :

var isDom = document.getElementById?true:false;
var isIE  = document.all?true:false;
var isNS4 = document.layers?true:false;
var cellCount = 10;

function setprogress(pIdent, pValue, pString, pDeterminate)
{
        if (isDom)
            prog = document.getElementById(pIdent+'installationProgress');
        if (isIE)
            prog = document.all[pIdent+'installationProgress'];
        if (isNS4)
            prog = document.layers[pIdent+'installationProgress'];
	if (prog != null) 
	    prog.innerHTML = pString;

        if (pValue == pDeterminate) {
	    for (i=0; i < cellCount; i++) {
                showCell(i, pIdent, "hidden");	
            }
        }
        if ((pDeterminate > 0) && (pValue > 0)) {
            i = (pValue-1) % cellCount;
            showCell(i, pIdent, "visible");	
        } else {
            for (i=pValue-1; i >=0; i--) {
                showCell(i, pIdent, "visible");	
                if (isDom)
                    document.getElementById(pIdent+'progressCell'+i+'A').innerHTML = i;
                if (isIE)
                    document.all[pIdent+'progressCell'+i+'A'].innerHTML = i;
                if (isNS4)
                    document.layers[pIdent+'progressCell'+i+'A'].innerHTML = i;
            }
	}
}

function showCell(pCell, pIdent, pVisibility)
{
	if (isDom)
	    document.getElementById(pIdent+'progressCell'+pCell+'A').style.visibility = pVisibility;
	if (isIE)
	    document.all[pIdent+'progressCell'+pCell+'A'].style.visibility = pVisibility;
	if (isNS4)
	    document.layers[pIdent+'progressCell'+pCell+'A'].style.visibility = pVisibility;
