JavaScript - Hiding Text For Password

Hello All,

I am new to this forum and to web development,
I am trying to hide div based on conditions..

This is the scenario:
the div should never appear again for that user, until i write another server side message.

lets say i write a message today saying " we are really sorry, but the website will be don for one hour today"

and you login today, the message will be displayed, when you click close its closed, it wont appear again for you, until i post another message,

but each message would have an expiration date, if i post a message which would be displayed to every user, i should decide how long i want it displayed, maybe 24 hrs, so in 24 hrs the message should no longer display.


Please help me out on this...I need a solution fast...

Thanks

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

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,

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.

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!

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 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 have this simple checkbox menu
http://myresearchfinder.com/dev/checktest.html

If you check the cancer box a div will appear. If you check lung, another menu pops up. If you check colon nothing appears because it's behind the lung div. I am aware of z-index. But because a person may go back and forth between menus I need a way to make sure the appropriate div is always on top. Any ideas?

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>
						<option value="universitiesDiv"> كلية </option>
						<option value="universitiesDiv">درجة البكالوريوس</option>
						<option value="universitiesDiv">درجة عليا</option>
						<option value="universitiesDiv">دكتوراه / ما بعد الدكتوراه</option>
						<option value="07">اسألني فيما بعد</option>
						</select>
						</span>
						</div> 
						</td></tr></table>
					</div>

Hi, I wondering if anyone can help:

I've got rows of divs in this manner

<div class="row">This is row 1 <a href="click">click here to show more</a></div>
<div class="hidden row"><p> hidden text for row 1</p></div>
<div class="row">This is row 2 <a href="click">click here to show more</a></div>
<div class="hidden row"><p> hidden text for row 2</p></div>
<div class="row">This is row 3 <a href="click">click here to show more</a></div>
<div class="hidden row"><p> hidden text for row 3</p></div>
<div class="row">This is row 4 <a href="click">click here to show more</a></div>
<div class="hidden row"><p> hidden text for row 4</p></div>

I wish to have some javascript to toggle the hidden row for its corresponding link.

Please can someone help point me to an example if available. Any help will be greatly appreciated

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

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>

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.

Hi

Sorry if the title is a bit vague.

I have a single page with fixed background and <A name=section> / #section type menu

also have a margin-bottom: 1000px; so content isnt visible until the link in menu is pressed

I am using the smooth pack javascript so it scrolls rather than jumps straight to the #section content

what I want to do is have the content invisible until it reaches the fixed background

is it possible to have content invisible until it scrolls into a div, i'm sure it is

the fixed background is about 800x500 and black all round so the text is visible, I could alter to have any text black but at the moment its blue and white

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>

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