Changing style sheets not working in IE - javascript

I've got a style sheet changer with javascript but it doesn't work in IE while working good in Firefox and Chrome. The HTML code I'm using is this:
<head>
<link href="defualt.css" rel="stylesheet" type="text/css" />
<link href="theme1.css" title="theme1" rel="alternate stylesheet" type="text/css" />
<link href="theme2.css" title="theme2" rel="alternate stylesheet" type="text/css" />
<link href="theme3.css" title="theme3" rel="alternate stylesheet" type="text/css" />
<script type="text/javascript" src="javascript.js"></script>
</head>
<body>
<form>
<select id="myList" >
<option value="default">Default</option>
<option value="theme1">Theme 1</option>
<option value="theme2">Theme 2</option>
<option value="theme3">Theme 3</option>
</select>
</form>
</body>
And the javascript:
function setActiveStyleSheet(title) {
var i, a, main;
for (i = 0; (a = document.getElementsByTagName("link")[i]) ; i++) {
if (a.getAttribute("rel").indexOf("style") != -1 && a.getAttribute("title")) {
a.disabled = true;
if (a.getAttribute("title") == title) a.disabled = false;
}
}
createCookie("style", title, 7);
}
function getActiveStyleSheet() {
var i, a;
for (i = 0; (a = document.getElementsByTagName("link")[i]) ; i++) {
if (a.getAttribute("rel").indexOf("style") != -1 && a.getAttribute("title") && !a.disabled) return a.getAttribute("title");
}
}
function getPreferredStyleSheet() {
var i, a;
for (i = 0; (a = document.getElementsByTagName("link")[i]) ; i++) {
if (a.getAttribute("rel").indexOf("style") != -1
&& a.getAttribute("rel").indexOf("alt") == -1
&& a.getAttribute("title")
) return a.getAttribute("title");
}
}
function getTheme() {
var storedThemeVal = readCookie('selectedTheme');
if (storedThemeVal != null && storedThemeVal != "") {
for (var i = 0; i < selectBox.options.length; i++) {
if (selectBox.options[i].value == storedThemeVal) {
selectBox.selectedIndex = i;
}
}
}
}
function setTheme() {
var selectedThemeVal = selectBox.options[selectBox.selectedIndex].value;
createCookie('selectedTheme', selectedThemeVal);
}
function createCookie(name, value, days) {
if (days) {
var date = new Date();
date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
var expires = "; expires=" + date.toGMTString();
}
else expires = "";
document.cookie = name + "=" + value + expires + "; path=/";
}
function readCookie(name) {
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for (var i = 0; i < ca.length; i++) {
var c = ca[i];
while (c.charAt(0) == ' ') c = c.substring(1, c.length);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length, c.length);
}
return null;
}
function initiate()
{
window.selectBox = document.getElementById("myList");
var cookie = readCookie("style");
var title = cookie ? cookie : getPreferredStyleSheet();
setActiveStyleSheet(title);
getTheme();
selectBox.onchange = function () {
setActiveStyleSheet(this.value);
setTheme();
};
}
window.onload = initiate;
I can't understand why this won't work in IE since it's working so good in the other browsers. And I prefer to keep all my javascript in my separate document javascript.js as well as I don't want to work with a library.

i don't know whether there is any other wrong in your code.but i know getElementsByClassName() is not supported lt IE9,and in ie,to the event binding method is attachEvent().I hope it can help u.

Probably because IE has issues getting non-standard attributes from elements.
Also you might want to try the following instead of 'getElementsByClassName()' (not supported)
i = 0;
a = document.getElementsByTagName("a");
while (element = a[i++]) {
if (element.className == "sidemenu-maincat") {
// blah blah...
}
}

Making my javaScript popup to appear only once

I am creating a JavaScript popup. The code is as below.
The HTML:
<div id="ac-wrapper" style='display:none' onClick="hideNow(event)">
<div id="popup">
<center>
<h2>Popup Content Here</h2>
<input type="submit" name="submit" value="Submit" onClick="PopUp('hide')" />
</center>
</div>
</div>
The CSS:
#ac-wrapper {
position: fixed;
top: 0;
left: 0;
width: 100%;
height: 100%;
background: url("images/pop-bg.png") repeat top left transparent;
z-index: 1001;
}
#popup {
background: none repeat scroll 0 0 #FFFFFF;
border-radius: 18px;
-moz-border-radius: 18px;
-webkit-border-radius: 18px;
height: 361px;
margin: 5% auto;
position: relative;
width: 597px;
}
The Script:
function PopUp(hideOrshow) {
if (hideOrshow == 'hide') document.getElementById('ac-wrapper').style.display = "none";
else document.getElementById('ac-wrapper').removeAttribute('style');
}
window.onload = function () {
setTimeout(function () {
PopUp('show');
}, 0);
}
function hideNow(e) {
if (e.target.id == 'ac-wrapper') document.getElementById('ac-wrapper').style.display = 'none';
}
The jsFiddle Link:
http://jsfiddle.net/K9qL4/2/
The Issue:
The above script works fine, but I need to make the popUp to appear only once on my page.
i.e, when the user closes the popup, it should not appear until the user restarts the browser or clears his cache/cookie.
I tried using the below cookie script, but it does not work for me.
<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
var expDays = 1; // number of days the cookie should last
var page = "myPage.html";
var windowprops = "width=300,height=200,location=no,toolbar=no,menubar=no,scrollbars=no,resizable=yes";
function GetCookie (name) {
var arg = name + "=";
var alen = arg.length;
var clen = document.cookie.length;
var i = 0;
while (i < clen) {
var j = i + alen;
if (document.cookie.substring(i, j) == arg)
return getCookieVal (j);
i = document.cookie.indexOf(" ", i) + 1;
if (i == 0) break;
}
return null;
}
function SetCookie (name, value) {
var argv = SetCookie.arguments;
var argc = SetCookie.arguments.length;
var expires = (argc > 2) ? argv[2] : null;
var path = (argc > 3) ? argv[3] : null;
var domain = (argc > 4) ? argv[4] : null;
var secure = (argc > 5) ? argv[5] : false;
document.cookie = name + "=" + escape (value) +
((expires == null) ? "" : ("; expires=" + expires.toGMTString())) +
((path == null) ? "" : ("; path=" + path)) +
((domain == null) ? "" : ("; domain=" + domain)) +
((secure == true) ? "; secure" : "");
}
function DeleteCookie (name) {
var exp = new Date();
exp.setTime (exp.getTime() - 1);
var cval = GetCookie (name);
document.cookie = name + "=" + cval + "; expires=" + exp.toGMTString();
}
var exp = new Date();
exp.setTime(exp.getTime() + (expDays*24*60*60*1000));
function amt(){
var count = GetCookie('count')
if(count == null) {
SetCookie('count','1')
return 1
}
else {
var newcount = parseInt(count) + 1;
DeleteCookie('count')
SetCookie('count',newcount,exp)
return count
}
}
function getCookieVal(offset) {
var endstr = document.cookie.indexOf (";", offset);
if (endstr == -1)
endstr = document.cookie.length;
return unescape(document.cookie.substring(offset, endstr));
}
function checkCount() {
var count = GetCookie('count');
if (count == null) {
count=1;
SetCookie('count', count, exp);
window.open(page, "", windowprops);
}
else {
count++;
SetCookie('count', count, exp);
}
}
// End -->
</script>
I thing in this case is better to use localStorage instead cookie.
localStorage have a more intuitive interface and user cannot restrict
this feature to be used. I have changed your code.
function PopUp(hideOrshow) {
if (hideOrshow == 'hide') {
document.getElementById('ac-wrapper').style.display = "none";
}
else if(localStorage.getItem("popupWasShown") == null) {
localStorage.setItem("popupWasShown",1);
document.getElementById('ac-wrapper').removeAttribute('style');
}
}
window.onload = function () {
setTimeout(function () {
PopUp('show');
}, 0);
}
function hideNow(e) {
if (e.target.id == 'ac-wrapper') document.getElementById('ac-wrapper').style.display = 'none';
}
Here is working jsFiddle.
http://jsfiddle.net/zono/vHG7j/
Best regards.
To not show this untill restart browser - use local storage
localStorage.setItem("setted",true);
localStorage.getItem("setted");
FIDDLE
To not show untill clear cache\cookie use cookies
document.cookie = "setted=true";
document.cookie.indexOf("setted=true")!=-1
FIDDLE
I've used local storage instead of cookie for the reason mentioned otherwise
however, I have added the comparison, and checked that you want to show it (also added a reset button for you to test easily)
fiddle is: http://jsfiddle.net/K9qL4/8/
function PopUp(hideOrshow) {
if (hideOrshow === 'hide') {
document.getElementById('ac-wrapper').style.display = "none";
}
else if(localStorage.getItem("popupWasShown") !== "1" && hideOrshow === 'show') {
document.getElementById('ac-wrapper').removeAttribute('style');
localStorage.setItem("popupWasShown", "1");
}
}
window.onload = function () {
setTimeout(function () {
PopUp('show');
}, 1000);
}
function hideNow(e) {
if (e.target.id == 'ac-wrapper') {
document.getElementById('ac-wrapper').style.display = 'none';
localStorage.setItem("popupWasShown", "1");
}
}
document.getElementById("reset").onclick = function() {
localStorage.setItem("popupWasShown", "3");
}
We have slightly modified the code with session storage in order to load the popup whenever the page is loaded (several times per day or in a new window/tab):
else if(sessionStorage.getItem("popupWasShown") == null) {
sessionStorage.setItem("popupWasShown",1);
document.getElementById('ac-wrapper').removeAttribute('style');
}
Full code:
function PopUp(hideOrshow) {
if (hideOrshow == 'hide') {
document.getElementById('ac-wrapper').style.display = "none";
}
else if(sessionStorage.getItem("popupWasShown") == null) {
sessionStorage.setItem("popupWasShown",1);
document.getElementById('ac-wrapper').removeAttribute('style');
}
}
window.onload = function () {
setTimeout(function () {
PopUp('show');
}, 0);
}
function hideNow(e) {
if (e.target.id == 'ac-wrapper') document.getElementById('ac-wrapper').style.display = 'none';
}
**CSS:**
<style>
#popup{
display:none;
}
</style>
**HTML:**
<div id="popup">
<center>
<h2>Popup Content Here</h2>
<input type="button" name="submit" value="Submit"/>
</center>
</div>
**JS:**
<script>
getCookie = function(data){
var dset = data + "=";
var c = document.cookie.split(';');
for(var i=0; i<c.length; i++){
var val = c[i];
while (val.charAt(0)==' ') val = val.substring(1, val.length);
if(val.indexOf(dset) == 0) return val.substring(dset.length, val.length)
}
return "";
}
if(getCookie("popupShow") != "yes"){
document.getElementById('popup').style.display = "block";
//set cookie
document.cookie = 'popupShow=yes; expires=Sun, 1 Jan 2023 00:00:00 UTC; path=/'
}
</script>
Try this one it works on my end;

Javascript Expandable Header not working correctly

I am using a piece of Javascript that enables the user to expand a h3 tag in my HTML document. It is working perfectly however when I refresh my page the first time the header is contracted and then when I refresh it a second time the header is expanded again.
I would like it to just stay expanded and not contract ever but I am unsure what changes I may need to make to the code:
I should point out that when the user visits the page for the first time the header is already expanded. I do that by calling the function from within the body tag.
<body onLoad="expandcontent('sc1')">
This is the code:
var enablepersist = "on" //Enable saving state of content structure using session cookies? (on/off)
var collapseprevious = "yes" //Collapse previously open content when opening present? (yes/no)
if (document.getElementById) {
document.write('<style type="text/css">')
document.write('.switchcontent{display:none;}')
document.write('</style>')
}
function getElementbyClass(classname) {
ccollect = new Array()
var inc = 0
var alltags = document.all ? document.all : document.getElementsByTagName("*")
for (i = 0; i < alltags.length; i++) {
if (alltags[i].className == classname)
ccollect[inc++] = alltags[i]
}
}
function contractcontent(omit) {

while (ccollect[inc]) {
if (ccollect[inc].id != omit)

Create and read cookie in drop down menu with javascript

I'm using this HTML code:
<head>
<link href="defualt.css" rel="stylesheet" type="text/css" />
<link href="theme1.css" title="theme1" rel="alternate stylesheet" type="text/css" />
<link href="theme2.css" title="theme2" rel="alternate stylesheet" type="text/css" />
<link href="theme3.css" title="theme3" rel="alternate stylesheet" type="text/css" />
<script type="text/javascript" src="javascript.js"></script>
</head>
<body>
<form>
<select id="myList" >
<option value="default">Default</option>
<option value="theme1">Theme 1</option>
<option value="theme2">Theme 2</option>
<option value="theme3">Theme 3</option>
</select>
</form>
</body>
It's a form to change style sheets. This is the javascript I'm using:
function setActiveStyleSheet(title) {
var i, a, main;
for(i=0; (a = document.getElementsByTagName("link")[i]); i++) {
if(a.getAttribute("rel").indexOf("style") != -1 && a.getAttribute("title")) {
a.disabled = true;
if(a.getAttribute("title") == title) a.disabled = false;
}
}
createCookie("style", title, 7);
}
function getActiveStyleSheet() {
var i, a;
for(i=0; (a = document.getElementsByTagName("link")[i]); i++) {
if(a.getAttribute("rel").indexOf("style") != -1 && a.getAttribute("title") && !a.disabled) return a.getAttribute("title");
}
return null;
}
function getPreferredStyleSheet() {
var i, a;
for(i=0; (a = document.getElementsByTagName("link")[i]); i++) {
if(a.getAttribute("rel").indexOf("style") != -1
&& a.getAttribute("rel").indexOf("alt") == -1
&& a.getAttribute("title")
) return a.getAttribute("title");
}
return null;
}
function createCookie(name,value,days) {
if (days) {
var date = new Date();
date.setTime(date.getTime()+(days*24*60*60*1000));
var expires = "; expires="+date.toGMTString();
}
else expires = "";
document.cookie = name+"="+value+expires+"; path=/";
}
function readCookie(name) {
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for(var i=0;i < ca.length;i++) {
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1,c.length);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
}
return null;
}
window.onload = function(e) {
var cookie = readCookie("style");
var title = cookie ? cookie : getPreferredStyleSheet();
setActiveStyleSheet(title);
}
var cookie = readCookie("style");
var title = cookie ? cookie : getPreferredStyleSheet();
setActiveStyleSheet(title);
function initate()
{
document.getElementById("myList").onchange = function() {
setActiveStyleSheet(this.value);
return false
};
}
window.onload = initate;
The changing of the style sheets work great but I want the option chosen in the menu to stay after I reload the page. This works as it should in Firefox but not in Chrome. I'm quite new to javascripts and I haven't written all of this code myself so I don't fully understand all of it. Is it possible to save the chosen option of the menu in the same cookie or is it better/easier to create a new one?
If you're reloading the page, there is nothing you can do to persist the state of the drop down selection within the page (HTML, Javascript) itself. I would suggest you use a cookie to store the current selection, read in the value on page load, and set the option in the drop down accordingly.
For cookie JS, see: http://www.quirksmode.org/js/cookies.html
function initate() {
window.selectBox = document.getElementById("myList");
var cookie = readCookie("style");
var title = cookie ? cookie : getPreferredStyleSheet();
setActiveStyleSheet(title);
getTheme();
selectBox.onchange = function () {
setActiveStyleSheet(this.value);
setTheme();
};
}
window.onload = initate;
function setActiveStyleSheet(title) {
var i, a, main;
for (i = 0; (a = document.getElementsByTagName("link")[i]) ; i++) {
if (a.getAttribute("rel").indexOf("style") != -1 && a.getAttribute("title")) {
a.disabled = true;
if (a.getAttribute("title") == title) a.disabled = false;
}
}
createCookie("style", title, 7);
}
function getActiveStyleSheet() {
var i, a;
for (i = 0; (a = document.getElementsByTagName("link")[i]) ; i++) {
if (a.getAttribute("rel").indexOf("style") != -1 && a.getAttribute("title") && !a.disabled) return a.getAttribute("title");
}
}
function getPreferredStyleSheet() {
var i, a;
for (i = 0; (a = document.getElementsByTagName("link")[i]) ; i++) {
if (a.getAttribute("rel").indexOf("style") != -1
&& a.getAttribute("rel").indexOf("alt") == -1
&& a.getAttribute("title")
) return a.getAttribute("title");
}
}
function getTheme() {
var storedThemeVal = readCookie('selectedTheme');
if (storedThemeVal != null && storedThemeVal != "") {
for (var i = 0; i < selectBox.options.length; i++) {
if (selectBox.options[i].value == storedThemeVal) {
selectBox.selectedIndex = i;
}
}
}
}
function setTheme() {
var selectedThemeVal = selectBox.options[selectBox.selectedIndex].value;
createCookie('selectedTheme', selectedThemeVal);
}
function createCookie(name, value, days) {
if (days) {
var date = new Date();
date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
var expires = "; expires=" + date.toGMTString();
}
else expires = "";
document.cookie = name + "=" + value + expires + "; path=/";
}
function readCookie(name) {
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for (var i = 0; i < ca.length; i++) {
var c = ca[i];
while (c.charAt(0) == ' ') c = c.substring(1, c.length);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length, c.length);
}
return null;
}
Note that Chrome does not support local cookies by default (file:// protocol). Either test this in a server environment, or enable file cookies by adding --enable-file-cookies to your shortcut to Chrome (so, if you have a shortcut, right click on it, click properties and edit the Target to include --enable-file-cookies at the very end, after the quotes).
Alternatively, you could also modify the URL (user a query string parameter) to store/read the current selection (similar to above). However, this of course would be lost if the user leaves the site and comes back to it.

javascript form cookies - select only opening cookie for first 10 indexes

I have never used cookies before, so I am using a peice of code I am very unfamiliar with.
It was working all fine, until I noticed just now that for select boxes, it is not working for any values after the tenth index. (for index 10 and above).
I have looked at the cookie stored on my system, and it appears t be saving them correctly. (I saw select10) ETC stored properly.
When it runs onload of body however, it is not loading in the values properly.
Here is the cookie code I am using:
<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
var expDays = 100;
var exp = new Date();
exp.setTime(exp.getTime() + (expDays*24*60*60*1000));
function getCookieVal (offset) {
var endstr = document.cookie.indexOf (";", offset);
if (endstr == -1) { endstr = document.cookie.length; }
return unescape(document.cookie.substring(offset, endstr));
}
function GetCookie (name) {
var arg = name + "=";
var alen = arg.length;
var clen = document.cookie.length;
var i = 0;
while (i < clen) {
var j = i + alen;
if (document.cookie.substring(i, j) == arg) return getCookieVal (j);
i = document.cookie.indexOf(" ", i) + 1;
if (i == 0) break;
}
return null;
}
function SetCookie (name, value) {
var argv = SetCookie.arguments;
var argc = SetCookie.arguments.length;
var expires = (argc > 2) ? argv[2] : null;
var path = (argc > 3) ? argv[3] : null;
var domain = (argc > 4) ? argv[4] : null;
var secure = (argc > 5) ? argv[5] : false;
document.cookie = name + "=" + escape (value) +
((expires == null) ? "" : ("; expires=" + expires.toGMTString())) +
((path == null) ? "" : ("; path=" + path)) +
((domain == null) ? "" : ("; domain=" + domain)) +
((secure == true) ? "; secure" : "");
}
// use the following code to call it:
// <body onLoad="cookieForms('open', 'form_1', 'form_2', 'form_n')" onUnLoad="cookieForms('save', 'form_1', 'form_2', 'form_n')">
function cookieForms() {
var mode = cookieForms.arguments[0];
for(f=1; f<cookieForms.arguments.length; f++) {
formName = cookieForms.arguments[f];
if(mode == 'open') {
cookieValue = GetCookie('saved_'+formName);
if(cookieValue != null) {
var cookieArray = cookieValue.split('#cf#');
if(cookieArray.length == document[formName].elements.length) {
for(i=0; i<document[formName].elements.length; i++) {
if(cookieArray[i].substring(0,6) == 'select') { document[formName].elements[i].options.selectedIndex = cookieArray[i].substring(7, cookieArray[i].length-1); }
else if((cookieArray[i] == 'cbtrue') || (cookieArray[i] == 'rbtrue')) { document[formName].elements[i].checked = true; }
else if((cookieArray[i] == 'cbfalse') || (cookieArray[i] == 'rbfalse')) { document[formName].elements[i].checked = false; }
else { document[formName].elements[i].value = (cookieArray[i]) ? cookieArray[i] : ''; }
}
}
}
}
if(mode == 'save') {
cookieValue = '';
for(i=0; i<document[formName].elements.length; i++) {
fieldType = document[formName].elements[i].type;
if(fieldType == 'password') { passValue = ''; }
else if(fieldType == 'checkbox') { passValue = 'cb'+document[formName].elements[i].checked; }
else if(fieldType == 'radio') { passValue = 'rb'+document[formName].elements[i].checked; }

cookieValue = cookieValue + passValue + '#cf#';
}
cookieValue = cookieValue.substring(0, cookieValue.length-4); // Remove last delimiter
SetCookie('saved_'+formName, cookieValue, exp);
}
}
}
// End -->
</script>
I beleive the problem lies with the following line, found about 3/4 of the way down the code block above (line 68):
if(cookieArray[i].substring(0,6) == 'select') { document[formName].elements[i].options.selectedIndex = cookieArray[i].substring(7, cookieArray[i].length-1); }
Just for reference, here is the opening body tag I am using:
<body style="text-align:center;" onload="cookieForms('open', 'ramsform', 'decksform', 'hullsform', 'crewform', 'shipwrightform'); Swap(crew0z,'crew0i'); Swap(crew1z,'crew1i'); Swap(crew2z,'crew2i'); Swap(crew3z,'crew3i'); Swap(crew4z,'crew4i'); Swap(crew5z,'crew5i'); Swap(crew6z,'crew6i'); Swap(crew7z,'crew7i'); Swap(crew8z,'crew8i'); Swap(crew9z,'crew9i');" onunload="cookieForms('save', 'ramsform', 'decksform', 'hullsform', 'crewform', 'shipwrightform');">
(Please ignore the swap()'s as they are unrelated)

In both the open and save codes, change:
document[formName].elements[i].options.selectedIndex
to:
document[formName].elements[i].selectedIndex
options is an array of all the options, the selectedIndex property belongs to the select element that contains them.
Change:
cookieArray[i].substring(7, cookieArray[i].length-1)
to:
cookieArray[i].substring(6)
You were off by 1 because you forgot that it's 0-based counting. The second argument isn't needed, it defaults to the rest of the string.
The reason it worked for the first 10 menu items is a quirk of substring: if the second argument is lower than the first, it swaps them! So "select5".substring(7, 6) is treated as "select5".substring(6, 7), which gets the last character of the string. But for the longer strings, it was `"select35".substring(7, 7), which is an empty string.

Highlight the parent even when a child element is selected (opencart)

Last week I created an e-shop with opencart. Now I'm trying to customize the default top menu. What I want to do is to keep the parent highlighted even when a child element is selected
I highlight the current page with this js :
<script type="text/javascript" >
function extractPageName(hrefString)
{
var arr = hrefString.split('/');
return (arr.length < 2) ? hrefString : arr[arr.length-2].toLowerCase() + arr[arr.length-1].toLowerCase();
}
function setActiveMenu(arr, crtPage)
{
for (var i=0; i < arr.length; i++)
{
if(extractPageName(arr[i].href) == crtPage)
{
if (arr[i].parentNode.tagName != "DIV")
{
arr[i].className = "current";
arr[i].parentNode.className = "current";
}
}
}
}
function setPage()
{
hrefString = document.location.href ? document.location.href :document.location ;
if (document.getElementById("menu") !=null)
setActiveMenu(document.getElementById("menu").getElementsByTagName("a"),extractPageName(hrefString));
}
window.onload=function()
{
setPage();
}
</script>
Any help would be greatly appreciated.
p.s. sorry for my English, if you can't understand what I want to make.
I figured it out. Tooraj gives me the idea. Here is my code :
<script type="text/javascript" >
function extractPageName(hrefString)
{
var arr = hrefString.split('/');
return (arr.length < 2) ? hrefString : arr[arr.length-2].toLowerCase() + arr[arr.length-1].toLowerCase();
}
function setActiveMenu(arr, crtPage)
{
for (var i=0; i < arr.length; i++)
{
if(extractPageName(arr[i].href) == crtPage)
{
if (arr[i].parentNode.parentNode.parentNode.parentNode.tagName != "DIV",
arr[i].parentNode.tagName != "DIV")
{
arr[i].className = "current";
arr[i].parentNode.parentNode.parentNode.parentNode.className = "current";
arr[i].parentNode= "current";
}
}
}
}
function setPage()
{
hrefString = document.location.href ? document.location.href :document.location ;
if (document.getElementById("menu") !=null)
setActiveMenu(document.getElementById("menu").getElementsByTagName("a"),extractPageName(hrefString));
}
window.onload=function()
{
setPage();
}
</script>
