JavaScript - Nested Loops, One Timed

Hello everyone,

I have been working on this function but no luck so far. Basically this is a simple vertical navigation menu, and I am just trying to to show or hide the sub-menus (unordered lists) with onmouseover & onmouseout. I can do this very easily with just css or inline events, but I'm just trying to figure it out the way I already set it up. So I am looping through the ULs first, then I loop through the LIs. Furthermore I find the right LI elements by checking their class names, and if they exist I trigger the onmouseover & onmouseout events on them so the ULs will appear/disappear. The issue is that this works only for the last list item because I am guessing of a closure. So instead of getting each item individually at each event, instead it gives me the last list item. I have searched the web for a while now about closures and such, but all the examples I find talk about nested functions and a single loop, which isn't my case because I have two loops and only one function. Any help would be appreciated.


HTML Code:
Code:

		<div id="navWrapper">
			<ul>
			  <li class="triggers"><a href="#">Item 1</a>
				<ul class="subMenu">
				  <li><a href="#">Item 1.1</a></li>
				  <li><a href="#">Item 1.2</a></li>
				  <li><a href="#">Item 1.3</a></li>
				</ul>
			  </li>

			  <li class="triggers"><a href="#">Item 2</a>
				<ul class="subMenu">
				  <li><a href="#">Item 2.1</a></li>
				  <li><a href="#">Item 2.2</a></li>
				  <li><a href="#">Item 2.3</a></li>
				</ul>
			  </li>
			  
			  <li class="triggers"><a href="#">Item 3</a>
				<ul class="subMenu">
				  <li><a href="#">Item 3.1</a></li>
				  <li><a href="#">Item 3.2</a></li>
				  <li><a href="#">Item 3.3</a></li>
				</ul>
			  </li>
			</ul>
		</div>

Javascript Code:
Code:

<script type="text/javascript">		
function hoverSh () {
	var navWrap = document.getElementById('navWrapper');
	var uls = navWrap.getElementsByTagName('ul'); 
	var listItems = navWrap.getElementsByTagName('li');
	
	for (var i=0; i<uls.length; i++) {
		if (uls[i].className == "subMenu") {
		var theUls = uls[i];
			for (var j=0, c=listItems.length; j<c; j++) {
				if (listItems[j].className == "triggers") {
					var theItems = listItems[j];

							theItems.onmouseover = function () {//alert(this.nodeName + i);return false;
								theUls.style.display = 'block';
							}
							
							theItems.onmouseout = function () {
								theUls.style.display = 'none';
							}
							
				}//end inner if
			}//end inner loop w/ j
		}//end if
	}//end outer loop w/ i
}
window.onload = hoverSh;
</script>

Any links pointing to simplified tutorials on closures would be helpful too. I thought I understood them but I guess not!

I once bought some plans on the net and was sent a link that said I could open so many times or for 1 week, I cant remember exactly. But now I am doing a web site and need a link like that any ideas. I would prefer it to open only so many times.

I need an timed button. When you come to site, you must wait in that site ?? seconds and then button comes pressable.

**Solved**

Folks

I'm so in the dark about this that I couldn't even think of a sensible title for the thread!

One of my colleagues reckons that some years ago she worked on a website that contained images that were set to be visible to users only between certain dates (different dates for different images, so an image representing January would be visible only during January, and so on). Does this sound like something familiar? If so, would it be done using Javascript?

Thanks

Hi everyone! I'm new to this forum for posting, but i've been reading threads on this site for a few months now.. seems like a decent place to get info... so, hello everyone! My name's Will, (musical moniker on soundcloud / fb etc is StrangeFlow, i make electronic music, funk, hip hop, etc... ) ..I'm 25, I'm in Lansing , Michigan, my hometown (but still have residency in NorCal, where Im trying to get back to in a few months) I have some experience programming but i'm sure not as much as some of the experts on here

i dont know if it's bad etiquette to post a question in my first thread but i have a good question that hasn't been able to get resolved, and I figured someone on here might have some good advice..

Does anyone on here use soundcloud? they have a really nifty timed-comments bar, you can check it out on any soundcloud music page... Ive started seeing it on vimeo recently, I think it's something thats starting to catch on. Anyway,, I had an idea for a website, but the thing is, it would require a timed-comments bar. But.. my problem is, since I'm not as much of an expert as some of the people on here, what would it take to program it? I'm learning some C#, and I heard it would be that or php.. but.. I don't know.. any advice on that timed comments thing?

Any good points in the right direction would be extremely appreciated! Thanks everyone! I look forward to posting more in the future on this forum, and I'll gladly offer any of my advice on topics I am knowledgable.

Hello,

I am trying to create an image carousel for the website found here. As you can see everything works fine, however, I would like it to automatically scroll through the images every X seconds. I did not write this script (the credits are still in tact) and I know very very little about writing javascript, so I am hoping someone here can help. Thank you in advance for any replies and any suggestions/tips to making it a better script.

Hello, I am trying to have 4 different images change when the user hits the start button. The speed they change in is based on what selection they have chosen (fast = every second, med = 3 sec, slow = 5 sec), and this cycle repeats until the user has hit the stop button. However, I am struggling to get this to work and have looked around the web for help, but cannot find it.

I have not included any attempt of a code for the functions because I have tried at least 8 different things and have failed to get it to properly work each time. Also the array I set up does not work either.

Thank you for the help and your time,

First off, i have no idea what to do, because when i get beyond the realm of html/css, vb and php (some) i become lost. I hope someone can help me achieve this because i have no idea what i'm doing, and I've been at it for 2 weeks and no money to hire someone to do this for me. If you ever been in my situation, you know exactly how i feel. I have no code of my own to show you, but hope someone can still help me.

I'm have a number 0.0000000, and every min i need that number to increase to 0.0000000, than to 0.0000002 and so on and so forth. Every time i click a button, whatever the number has risen to, it will reset it back down to 0.0000000.

Can someone help me out with this?

Can someone tell me why this short script won't work?

Hi,

I've ben trying to figure this one out for days now and so I'd thought to give it a shoot here to see whether anybody can give me any advice or inspiration.

Basically what I am trying to do is command a click of a bottom for a certain set time.

for example:

On the google main search engine page. Once ive typed in a search for "skateboards". I would then like to command the "search" bottom to clicked at 10 pm at night thus executing the search for "skateboards" going into the next page with all the search results.

I was wondering if it would be possible to right a Java command that could be run in the Mozilla Fire Fox Scratch pad tool. ( Which is found under Tools --> Web Developer.)

Please let me know of anything. It would be very grateful.

Thanks,

Knowing just enough about javascript to get myself in trouble, I have put three timed javascripts to appear from 18 December to the 1 January on three pages of my sister's website. The scripts are on the main index for the site; the index page for the bibliography folder /bibliography/ and in the education folder on just one page: /education/educationlinks.html.

Part one of the script inserts the css file; part two of the script inserts a "snowing" script and part three inserts a "make it stop snowing/let it snow" script. Everything is working perfectly for the main index page and the bibliography page. But I cannot figure out why the 3rd "make it stop snowing/let it snow" refuses to show up on the page in the education folder (the snowing javascript IS working on all three pages).

There are no errors being thrown and the education page validates.

This is the coding for the 3rd script:

Code:

// snowscript part 3:   Show the script between 19-31 Dec and 1 Jan 

var date = new Date();
var d  = date.getDate();
var m = date.getMonth() + 1;
dm = d + m;

if  (m = 12) 
{
   if (d > 18)
   { document.write('<script src="/scripts/snowlinkswitch.js" type="text/javascript" id="snow"></script>');   
   }
   else 
   { 
   document.write('');
   }
}
else if (dm == 1,1)
  {
  document.write('<script src="/scripts/snowlinkswitch.js" type="text/javascript"></script>');
  }
else
  {
  document.write('');
  }

This is the coding for snowlinkswitch.js

Code:

function myhref(){
    document.getElementById('myAnchor').innerHTML="please let it snow!";
    document.getElementById('myAnchor').href=location.href;
    document.getElementById('myAnchor').title="let it snow! let it snow!";  
    document.getElementById('myAnchor').onclick="location.reload(); startstop('spanstyle'); return false;";
}

// 

document.write ('<div id="snowlinks"><img src="/images/snow3aa.gif" width="11" height="11" border="0" alt="*"> <a id="myAnchor" href="" onclick="myhref();hidesnow(); return false;" title="please make it stop snowing!">please make it stop snowing!<\/a> <img src="/images/snow3aa.gif" width="11" height="11" border="0" alt="*"></div> ');

I would search for a similar occurrence but have no clue about what search words to use. Does anyone here have an idea about what I have done incorrectly that is causing this to happen? Many thanks.

Hi, im fairly new at all this, so please forgive me if I have misunderstood the guidelines on posting threads for this topic.

Im needing some help with adding a timed delay for a widget I have on my website.

My website is hosted on moonfruit, a flash based web builder, its very beginners level, and so this makes me feel like the new kid at school posting on this forum.

however moonfruit does have a HTML/JavaScript snippet

Which allows me to paste in code and show the cooliris gallery

But is has become crucial to my websites completion that this widget must have a timed delay on it

ive been at google for days till the point where im seeing the same pages again, and have come across setTimeout, unfortunately that's as far as I can seem to go, ive tried pasting in the code in numerous places and I just cant get it to work, i have pasted in other JavaScript codes, and they have worked, so i am convinced that its just me being a noob, other than it being a limitation on moonfruit

I would appreciate any help with this

Here is the code that im trying to get a delayed time of 10 seconds or so.

[CODE]
<object id="o" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="845" height="350"><param name="movie" value="http://apps.cooliris.com/embed/cooliris.swf"/><param name="allowFullScreen" value="true" /><param name="allowScriptAccess" value="always"/><param name="flashvars" value="style=dark&backgroundColor=#0d0d0d&feed=api://www.flickr.com/?user=41683862@N04%26album=72157622009594203&glowColor=#FFFFFF&showSearch=false&showEmbed=false&show Tutorial=true&showChrome=true"/><embed type="application/x-shockwave-flash" src="http://apps.cooliris.com/embed/cooliris.swf" flashvars="style=dark&backgroundColor=#0d0d0d&feed=api://www.flickr.com/?user=41683862@N04%26album=72157622009594203&glowColor=#FFFFFF&showSearch=false&showEmbed=false&show Tutorial=true&showChrome=true" width="845" height="350" allowFullScreen="true" allowScriptAccess="always"></embed></object>

Again any help is most appreciated

Hi Guys,

I'm embarking on a new project - although I've hit a wall.

I require a page to refresh at a scheduled date and time, several times a day.

For example, I would like the web page to reload the index at 3:15PM

So if anyone has the web page open during that time, it will automatically refresh for them.

Timing is quite important so I would need the script to use the server (hosts) time and not the end users time.

I am currently deciding on which server language to use, although Javascript is probably a suitable option? or would ajax be more the thing for this?

The webpage must execute the refresh at the time 3:15pm, so no matter when someone visits the page, even if its hours before, it must refresh at that time.

If anyone has any pointers on the best way to achieve this and what language to start with I am forever greatful

I do a lot of image design work and although I have worked with a few coders in the past but I haven't gone too much into coding myself, but its something I'm going to take time to learn and get involved in, so I'm not looking for script hand outs here, mainly just a nudge in the right direction.

Thank you guys!!

I want to be able to display the whole contents of a text file containing 4 paragraphs of text, on a static web page, as soon as a video finishes playing on the page. The video is to be set to autorun as soon as the page loads in the browser.

The text file mentioned above, is to remain hidden when the page initially loads and the video is playing. Please I need your advice about what JavaScript code to use to achieve this effect, and where to place the code in the HTML code of the web page. I am new to website design and the use of JavaScript code.

I have seen examples of code used for the timed delay of the display of an image file, after a video has finished playing. I do not know how to apply this to the display of a text file.

I do not want to convert the whole text file into an image file, as I feel this would negatively affect the search engine optimisation of the page, if there is no text content on the page. Thank you.
