Cut & Paste Popup progress bar

-

Description: Todd's popup progress bar script is used to provide a visual update of an event in progress. Use it, for example, to display a delay before redirecting to another page or loading a script/application. We've modified the script so it:
-Works in NS6 as well (default is IE4+ and NS4)
-Ability to specify duration of progress bar display (ie: 5 seconds)
Definitely a script with many uses.

Example:

Progress
Text link example
Directions: Simply copy the below into the <BODY> portion of your page:


<style>
<!--
.hide { position:absolute; visibility:hidden; }
.show { position:absolute; visibility:visible; }
-->
</style>

<SCRIPT LANGUAGE="JavaScript">

//Progress Bar script- by Todd King (tking@igpp.ucla.edu)
//Modified by JavaScript Kit for NS6, ability to specify duration
//Visit JavaScript Kit (http://javascriptkit.com) for script

var duration=3 // Specify duration of progress bar in seconds
var _progressWidth = 50; // Display width of progress bar.

var _progressBar = "|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||"
var _progressEnd = 5;
var _progressAt = 0;


// Create and display the progress dialog.
// end: The number of steps to completion
function ProgressCreate(end) {
// Initialize state variables
_progressEnd = end;
_progressAt = 0;

// Move layer to center of window to show
if (document.all) { // Internet Explorer
progress.className = 'show';
progress.style.left = (document.body.clientWidth/2) - (progress.offsetWidth/2);
progress.style.top = document.body.scrollTop+(document.body.clientHeight/2) - (progress.offsetHeight/2);
} else if (document.layers) { // Netscape
document.progress.visibility = true;
document.progress.left = (window.innerWidth/2) - 100+"px";
document.progress.top = pageYOffset+(window.innerHeight/2) - 40+"px";
} else if (document.getElementById) { // Netscape 6+
document.getElementById("progress").className = 'show';
document.getElementById("progress").style.left = (window.innerWidth/2)- 100+"px";
document.getElementById("progress").style.top = pageYOffset+(window.innerHeight/2) - 40+"px";
}

ProgressUpdate(); // Initialize bar
}

// Hide the progress layer
function ProgressDestroy() {
// Move off screen to hide
if (document.all) { // Internet Explorer
progress.className = 'hide';
} else if (document.layers) { // Netscape
document.progress.visibility = false;
} else if (document.getElementById) { // Netscape 6+
document.getElementById("progress").className = 'hide';
}
}

// Increment the progress dialog one step
function ProgressStepIt() {
_progressAt++;
if(_progressAt > _progressEnd) _progressAt = _progressAt % _progressEnd;
ProgressUpdate();
}

// Update the progress dialog with the current state
function ProgressUpdate() {
var n = (_progressWidth / _progressEnd) * _progressAt;
if (document.all) { // Internet Explorer
var bar = dialog.bar;
  } else if (document.layers) { // Netscape
var bar = document.layers["progress"].document.forms["dialog"].bar;
n = n * 0.55; // characters are larger
} else if (document.getElementById){
                var bar=document.getElementById("bar")
        }
var temp = _progressBar.substring(0, n);
bar.value = temp;
}

// Demonstrate a use of the progress dialog.
function Demo() {
ProgressCreate(10);
window.setTimeout("Click()", 100);
}

function Click() {
if(_progressAt >= _progressEnd) {
ProgressDestroy();
return;
}
ProgressStepIt();
window.setTimeout("Click()", (duration-1)*1000/10);
}

function CallJS(jsStr) { //v2.0
  return eval(jsStr)
}

</script>

<SCRIPT LANGUAGE="JavaScript">

// Create layer for progress dialog
document.write("<span id=\"progress\" class=\"hide\">");
document.write("<FORM name=dialog id=dialog>");
document.write("<TABLE border=2  bgcolor=\"#FFFFCC\">");

Add and delete columns dynamically in an HTML table

-
To add new rows to a table (or table section) you can use insertRow, but there isn't an equivalent insertColumn in the  DOM table methods . So what you can do is iterate the rows in the table (or table section), and call insertCell for each row. Javascript:   tableaddcolumn.js // 2006-08-21 - Created // 2006-11-05 - Modified - head and body function addColumn(tblId) { var tblHeadObj = document.getElementById(tblId).tHead; for (var h=0; h<tblHeadObj.rows.length; h++) { var newTH = document.createElement('th'); tblHeadObj.rows[h].appendChild(newTH); newTH.innerHTML = '[th] row:' + h + ', cell: ' + (tblHeadObj.rows[h].cells.length - 1) } var tblBodyObj = document.getElementById(tblId).tBodies[0]; for (var i=0; i<tblBodyObj.rows.length; i++) { var newCell = tblBodyObj.rows[i].insertCell(-1); newCell.innerHTML = '[td] row:' + i + ', cell: ' + (tblBodyObj.rows[i].cells.length - 1) } } function deleteColumn(tblId) { v...
