  </table>

addLoadEvent.js 使得頁面載入時候執行JS函式：

function addLoadEvent(func) {
  var oldonload = window.onload;
  if (typeof window.onload != 'function') {
    window.onload = func;
  } else {
    window.onload = function() {
      oldonload();
      func();
    }
  }
}

不動HTML程式碼的情況下，stripeTables.js隔行換色：

function stripeTables() {
  if (!document.getElementsByTagName) return false;
  var tables = document.getElementsByTagName("table");
  for (var i=0; i<tables.length; i++) {
    var odd = false;
    var rows = tables[i].getElementsByTagName("tr");
    for (var j=0; j<rows.length; j++) {
      if (odd == true) {
        addClass(rows[j],"odd");
        odd = false;
      } else {
        odd = true;
      }
    }
  }
}
function addClass(element,value) {
  if (!element.className) {
    element.className = value;
  } else {
    newClassName = element.className;
    newClassName+= " ";
    newClassName+= value;
    element.className = newClassName;
  }
}
addLoadEvent(stripeTables);

highlightRows.js 滑鼠經過有動態感：

function highlightRows() {
  if(!document.getElementsByTagName) return false;
  var rows = document.getElementsByTagName("tr");
  for (var i=0; i<rows.length; i++) {
    rows[i].onmouseover = function() {
      this.style.fontWeight = "bold";
    }
    rows[i].onmouseout = function() {
      this.style.fontWeight = "normal";
    }
  }
}
addLoadEvent(highlightRows);
