JQuery Animated Selector

-

Description: Select all elements that are in the progress of an animation at the time the selector is run.

Additional Notes:

  • Because :animated is a jQuery extension and not part of the CSS specification, queries using :animated cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. To achieve the best performance when using:animated to select elements, first select the elements using a pure CSS selector, then use .filter(":animated").

Example:

Change the color of any div that is animated.

<!DOCTYPE html>
<html>
<head>
  <style>
  div { background:yellow; border:1px solid #AAA; width:80px; height:80px; margin:0 5px; float:left; }
  div.colored { background:green; }
  </style>
  <script src="http://code.jquery.com/jquery-latest.js"></script>
</head>
<body>
  <button id="run">Run</button>

  <div></div>
  <div id="mover"></div>
  <div></div>
<script>

    $("#run").click(function(){
      $("div:animated").toggleClass("colored");
    });
    function animateIt() {
      $("#mover").slideToggle("slow", animateIt);
    }
    animateIt();
</script>
</body>
</html>

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...
