JavaScript - Divs Hiding Under Each Other

Hi,

If I want to hide a title / heading if a field below is not filled in, what would be the js for that?

I have an "Attachments" h2 heading and three following fields for the client to add up to three attachments. But if none are filled in I want the h2 heading to not display.

This is what I have so far:

var attachment1 ='{tag_attachment 1}'
var attachment2 ='{tag_attachment 2}'
var attachment3 ='{tag_attachment 3}'

===
if(attachment1 == '') {
document.getElementById('attachment1').style.display = 'none';
}

if(attachment2 == '') {
document.getElementById('attachment2').style.display = 'none';
}

if(attachment3 == '') {
document.getElementById('attachment3').style.display = 'none';
}

===
<div id="attachments">
<h2>Attachments</h2>
<p>{tag_attachment 1}<br />
{tag_attachment 2}<br />
{tag_attachment 3}</p>
</div>


This should take care of the three fields, but how do I tie in the heading too?

Thank you!

i am having some problem showing and hiding some div
i want to show the div with the id="universitiesDiv" on one point and the div id="highSchoolsDiv" on another depending on the user choice of selected option.
Code:

function Show (titleImg){
		// the id of the content element from the id of the title element
	var contentID = titleImg.id.replace (/title/, "content");
	var contentDiv = document.getElementById (contentID);
		contentDiv.style.display = "block";

	return false;
}

function Hide (titleImg){
		// the id of the content element from the id of the title element
	var contentID = titleImg.id.replace (/title/, "content");
	var contentDiv = document.getElementById (contentID);

		contentDiv.style.display = "none";

	return false;
}

the functions work fine i have tested them on input type="checkbox" and they work fine
Code:

<select name="education" id="education" 
						onfocus="Show(this.options[this.selectedIndex].value);">
						<option selected value="00">-الرجاء الاختيار-</option>
						<option value="highSchoolsDiv">مدرسة ثانوية</option>

Hi,

I got a table with hundreds of rows...and I want the user to be able to hide a single one by clicking on the table row.

How can I do this without typing in hundreds of ids like 1,2,3,4,5... Since you can't get elements by class and ids have to unique I'm not sure how to do this. Also the order of the rows will change when they get updated so it would end up being a mess of unordered ids.

Thanks.

This might not be as simple as the title suggests. It may be a CSS problem, please say so if you know it to be and I will move it to the correct forum.

Now for the question,

Please visit:

http://danielrhyshardy.com/header/demo.html

I am using the jquery plugin supersized to create a carousel of images in the background of the page. As you will see though, as the transition starts, the second image is visible. I only want it to be visible when it indeed starts to overlap the current image. (i.e when the bench image overlaps the trees etc)

Here is the CSS:

Code:

* { margin:0; padding:0; }
body { background:#111; height:100%; }
	img{ border:none; }
	
	
	
	#supersized { position:absolute; left:0; top:0; overflow:hidden; z-index:-999; height:50%; width:100%; }
		#supersized img{ width:auto; height:auto; position:relative; display:none; outline:none; border:none; }
			#supersized.speed img { -ms-interpolation-mode:nearest-neighbor; image-rendering: -moz-crisp-edges; }	/*Speed*/
			#supersized.quality img { -ms-interpolation-mode:bicubic; image-rendering: optimizeQuality; }			/*Quality*/
		
		#supersized a { z-index:-30; position:fixed; overflow:hidden; top:0; left:0; width:100%; height:50%; background:#111; display:block; }
			#supersized a.prevslide { z-index:-20; }
			#supersized a.activeslide { z-index:-10; }
			#supersized a.image-loading { background:#111 url(../img/progress.gif) no-repeat center center; width:100%; height:50%; }
			#supersized a.prevslide img, #supersized a.activeslide img{ display:inline; }

Thanks guys

OK, I've been working on this for quite some time now, and have it working, almost. lol. Hopefully someone here can lend a fresh pair of eyes to what I'm doing wrong (bare in mind, I don't know javascript very well at all). I'm creating a simple faq page for my site, but there's a lot of questions, so instead of lumping it all in at once, I'm using divs to store answers in that hide and reappear as my guests click on a question they want to see an answer too. ok, heres the basics of the code I'm using so far:

Code:

<script type="text/javascript">
function showit(boxName) 
	{
	theBox = document.getElementById(boxName);
	theBox.className = "boxVisible";
	}
</script>
<script type="text/javascript">
function hideit(boxName) 
	{
	theBox = document.getElementById(boxName);
	theBox.className = "boxHidden";
	}
</script>

That, is in the head section of my page. Then for the links and such I have:

Code:

<div><a href="link.html" onclick="showit('s11'); hideit('s12'); hideit('s13'); hideit('s14'); hideit('s15'); hideit('s16'); return false;">Do you shoot in color, or black and white?</a></div>
	<div id="s11">
		&nbsp;&nbsp;&nbsp;&nbsp; We shoot in color.&nbsp; 
		Color prints can be printed in black and white and come out perfectly 
		just as though they were shot in black and white.&nbsp; However if you 
		shoot in black and white, you can't print it in color.&nbsp; For this 
		reason we shoot all of our images in full color.
	</div>

obviously there are more questions that that, but I don't want to fill this screen with all of them either.

Ok, heres what its doing, when you click on the first question, no problem, the answer opens right up, appears where it should be, everythings great, except, that its also following the link and leaving the page. I get to a 404 error telling me that link.html does not exist on my server. So, apparently the

Code:

return false

isnt working.... what do I need to do here, I'm now lost...

OH, I should include the CSS I'm using for these DIV's so you can see what the javascript is calling on for them:

Code:

.boxVisible 
	{
	display: block;
	position:relative;
	left:25px;
	width:755px;
	overflow:auto;
	}
.boxHidden 
	{
	display: none;
	}

Thanks to ANYONE that can help out!

I don't mean for this to be an advertisement, and if its not allowed by all means I'll remove it from this post, but if you want to see my exact code that I'm using, you'll find the page I'm working on at http://www.smmahoney.com/index.php?page=faq

hello all...just joined up...very anxious to get my website improved with some of your kind help

i have this current JS running, but Im having some little issues i thought someone here could help me out with.

I want the background color to be #0f3559. But whenever I add this to the script it disables the buttons I have included.

Also, I would like to have just one "Show/Hide" button that does both functions rather than 2 seperate.

can anyone take a look? THANKS.

Hi all,

I have some javascript that when a link is clicked hides the div and when it is clicked again shows the div... what I want to do is reverse that, so it is intially hidden. I have tried changing the display none to different parts but it always shows on load:
Code:

function toggleDiv (divid) {
	if (document.getElementById (divid).style.display == 'none') {
		document.getElementById (divid).style.display = 'block';
	} else {
		document.getElementById (divid).style.display = 'none';
	}
}

Code:

<a href="javascript:;" class="showmorelink" onmousedown="toggleDiv('checks');">Safeguarding</a>

Can anyone advise?

Many thanks,

Hi,
Would someone here please help me with this script. I know I am a complete hack at this, but I need to get it to work. Your help is appreciated.

As you can see, based on the if statement, I need to leave the Div element below hidden, or un-hide it.

I know the first part works. The second part (after "else" ) is where I am having the problem.
Code:

<td>
<script type="text/javascript">
if ([fieldXX]==1)   
 {
 document.write("<a href='page1.asp?itemid=1234'><img src='images/btn-choose.gif' border='0' alt='choose button'</a>"); 
 } 
else
 {  
    var id = 'hide-buy-btn';
    var item = document.getElementById(id); 
 if (item) {
 item.className=(item.className=='hidden')?'unhidden':'hidden';
 }
 }
</script>

<div id="hide-buy-btn" class="hidden">
x
xother button code
x						
</div>
</td>

Hi guys, I am working with a plugin calld Hashslider which is a fairly simple div slider.

Here is the code for startrs Code:

// hashslider v0.9 by manuel huegel, copyright 2010
// mgoys.com


$(document).ready(function(){
					   
//get width and height of the wrapper and give it to the UL	
	var wrapperwidth = $('#slider').width() *  $('#slider ul > li').size();
	$('#slider ul').css('width', wrapperwidth);
	var wrapperheight = $('#slider').height();
	$('#slider ul').css('height', wrapperheight);	
						   
						   
//set my li width
	var width = $('#slider').width();
	$('#slider ul li').css('width', width);

//set my counter vars
	var counter = $('#slider ul > li').size();
	var decount = 1;
	var autocount = 1;
	
//create my number navigation
	var createNum = 1;
	$('#numbers li:first-child').html(createNum).addClass('activenum').attr('id', 'id1');
	while ( createNum != counter) {
	$('#numbers li:last-child').after('<li>  </li>');
	createNum++;
	$('#numbers li:last-child').html(createNum);
	$('#numbers li:last-child').attr('id', 'id' + createNum);
	}
	
//get my number-width (number navigation should always be centered)
	var numwidth = $('#numbers li:first-child').width() * $('#numbers li').size();
	$('#numbers').css('width', numwidth);


	
//slide the button to the next item
function goNext() {
	if ( decount != counter) {
	$('#slider ul').animate({ left: '-=' + $('#slider').width() }, 400, 'swing', function() { });
	$('.activenum').removeClass('activenum').next().addClass('activenum');
	decount++;
	window.location.hash = decount;
	}
}

function goBack() {
	if ( decount != 1) {
	$('#slider ul').animate({ left: '+=' + $('#slider').width() }, 400, 'swing', function() { });
	$('.activenum').removeClass('activenum').prev().addClass('activenum');
	decount--;
	window.location.hash = decount;
	}
}

//make the number clickable
$("#numbers li").click(function() { 
	//$('#info4').html( $(this).html() ); 
	var clickednum = $(this).html() * - $('#slider').width() + $('#slider').width();
	//$('#info4').html( clickednum );
	$('#slider ul').animate({ left: clickednum }, 400, 'swing', function() { });
	$('.activenum').removeClass('activenum');
	$(this).addClass('activenum');
	decount = $(this).html();
	window.location.hash = $(this).html();	
});


//thaths the hash-shizzle
if ( window.location.hash != '') {
//get hash, scroll to position
	var hashnum = window.location.hash.substr(1) * - $('#slider').width() + $('#slider').width();
	$('#slider ul').animate({ left: hashnum }, 0, function() { });
//set counters to position
	decount = window.location.hash.substr(1);
	$('.activenum').removeClass('activenum');
	var hashname = window.location.hash.substr(1);
	$('#id' + hashname).addClass('activenum');
}
	
//get my clickers
$("#right").click(function() { goNext(); });	
$("#left").click(function() { goBack(); });	


//get mousewheel function
$("#slider ul").mousewheel(function(event, delta) { if (delta > 0) { goBack();	event.stopPropagation();event.preventDefault(); } });
$("#slider ul").mousewheel(function(event, delta) { if (delta < 0) { goNext();  event.stopPropagation();event.preventDefault();	} });







});

As you will see the current code loops through all of the slides, and when it reaches the last (or first) the previous and next links become unclickable. I would like to go a stage further than this and make them dissapear entirely.

I don't know how to do this or even to start, I dont even know what function to edit.

Please help guys.

Thanks in advance

I want to hide my JavaScript but when I checked the FAQ of this forum, I saw that it said that it isn't possible.

But how did worldometers.info did it? Because I cant find the JavaScript source.

Hey - I'm pretty much a Javascript n00b, but I know enough to cut and pasted and do minor edits. I wanted some help with this problem I'm having or really just wanted to know if what I want is possible.

I would like to have the 'Previous' link hidden on the first image and then the 'Next' link hidden on the last. I wondered if there was some way I could do that based on the number, which I guess would be the ImgNum variable? Here's the code (pulled of Google):

Code:

Thanks for your help!

I'm new to web programming, and so I may be going about this all wrong but this is what I'm trying to do.

I'm creating an interface to access my google base, I can do that part without much trouble but to access the server you need to request a session token. This token has to be sent to the server along with your query. I use JS on the main page which calls a php script that requests the key, then calls the server for a full list of items which is then passed back to the javascript in JSON format. The user then selects a field from the option box and i need to requery the server for the updated list. But to do this i need to resend the session token, and this is where I'm having trouble.

I need to save this token, but im not sure the best way to go about this. I can pass it back to the JS portion and save it as a variable that i can then pass to the PHP script that queries the server, but im worried the key may contain private information about my log in information. Is there a way to make this token variable hidden in the JS so that the client could not see it? Or am i way off base and the client can't view any of the variables anyways?

If someone has a suggestion for me that would be much appreciated.

I want it to hide or kill the div box with an onmouseout
I've tried listeners functions and just plain vars. i can find a solution maybe here

this is the code in the external file

Code:

////////////////////////////////////////////////////////
////////////////////////////////////////////////////////
function move_box(an, box) {
  var cleft = 0;
  var ctop = 0;
  var obj = an;
  while (obj.offsetParent) {
    cleft += obj.offsetLeft;
    ctop += obj.offsetTop;
    obj = obj.offsetParent;
  }
  box.style.left = cleft + 'px';
  ctop += an.offsetHeight + 8;
  if (document.body.currentStyle &&
    document.body.currentStyle['marginTop']) {
    ctop += parseInt(
      document.body.currentStyle['marginTop']);
  }
  box.style.top = ctop + 'px';
}

function  show_hide_box (an, width, height, borderStyle) {
  var href = an.href;
  var boxdiv = document.getElementById(href);

  if (boxdiv != null) {
    if (boxdiv.style.display=='none') {
      move_box(an, boxdiv);
      boxdiv.style.display='block';
    } else 
      boxdiv.style.display='none';
    return false;
  }
  

  boxdiv = document.createElement('div');
  boxdiv.setAttribute('id', href);
  boxdiv.style.display = 'block';
  boxdiv.style.position = 'absolute';
  boxdiv.style.width = width + 'px';
  boxdiv.style.height = height + 'px';
  boxdiv.style.border = borderStyle;
  boxdiv.style.backgroundColor = '#fff';
  

  var contents = document.createElement('iframe');
  contents.scrolling = 'no';
  contents.frameBorder = '0';
  contents.style.width = width + 'px';
  contents.style.height = height + 'px';
  contents.src = href;

  boxdiv.appendChild(contents);
  document.body.appendChild(boxdiv);
  move_box(an, boxdiv);
  
  boxdiv.addEventListener('mouseout', show_hide_box(boxdiv),false);

  return false;
}
////////////////////////////////////////////////////////////////////////////////
////////////////////////////////////////////////////////////////////////////////

And you put this code in the body to call it.

Code:

///////////////////////////////////////////////////////////////////

<a href="../Menus/cleaners.html"  onMouseOver="return show_hide_box(this,416,124,'2px')" >Cleaners</a>

///////////////////////////////////////////////////////////////////

Alright, working on an ajax image uploader, and im a bit rusty with JS.

How would i go about hiding the form after the submit button is pressed, so it disappears? Heres my website. If you need the scripts, just ask.


Thanks in advance.
