Contumacious: THE resource for quality tutorials

To create a search engine for a site page, you must have the following code:

<SCRIPT language=JavaScript>
var NS4 = (document.layers);    
var IE4 = (document.all);
var win = window;    
var n   = 0;
function findInPage(str) {
  var txt, i, found;
  if (str == "")
    return false;
  if (NS4) {
    if (!win.find(str))
      while(win.find(str, false, true))
        n++;
    else
      n++;
    if (n == 0)
      alert("Not found.");
  }
  if (IE4) {
    txt = win.document.body.createTextRange();
    for (i = 0; i <= n && (found = txt.findText(str)) != false; i++) {
      txt.moveStart("character", 1);
      txt.moveEnd("textedit");
    }
    if (found) {
      txt.moveStart("character", -1);
      txt.findText(str);
      txt.select();
      txt.scrollIntoView();
      n++;
    }
    else {
      if (n > 0) {
        n = 0;
        findInPage(str);
      }
      else
        alert("Sorry, we could not find what you are looking for.");
   }
  }
  return false;
}
</SCRIPT>

Here's what it looks like: However, this search engine is the exact replicant of pressing the keys on your keyboard, CNTRL+F to find text on the page the user is on. This search engine can not search into other pages of your site, but only the page the search engine is on.
This search engine is compatible with IE (Internet Explorer).
