EDIT #1
Thanks to the 2 users who responded, their solutions worked great! Something I forgot to mention in the original post was, Is there any way to adjust the user's view so that when the expanded section is collapses by the user, their "view" (or the actual web page) can adjust up to an anchored spot?
ORIGINAL POST
I've got a section of a website that I want to first be collapsed and not able to be viewed by the user. Then, when they hit an arrow on the screen, the hidden content will then display AND the image needs to change from a "down" arrow to an "up" arrow.
I'm able to do this with the below code right now but I have to have two arrows. Can anyone help so that I only have one arrow on screen and it changes based on when the user clicks on it? I'd also like this to be able to be done an infinite amount of times by the user (ie if the user clicks the "down" arrow, the section expands and the arrow changes to an "up" arrow but then when the user hits that "up" arrow the section collapses and the arrow changes back to a "down" arrow. Possible?

Thanks for any help!
I have added your code and created a jsfiddle for you...
changed code:-
function sizeTbl(h) {
var tbl = document.getElementById('container');
tbl.style.display = h;
if (h == "block") {
document.getElementById('down').style.display = 'none';
document.getElementById('up').style.display = 'block';
} else {
document.getElementById('up').style.display = 'none';
document.getElementById('down').style.display = 'block';
}
}

I've taken out the parameter from your sizeTbl method
Then I'm getting the src property of the image (note I've given it an ID). Depending on the src we can show/hide the table and change the image property
Here's a jsFiddle
<script language="JavaScript" type="text/javascript">
<!--
function sizeTbl() {
var tbl = document.getElementById('tbl');
var icon = document.getElementById('toggle-table');
if (icon.src === 'down_arrow.png'){
tbl.style.display = 'block';
icon.src = 'up_arrow.png';
}
else {
tbl.style.display = 'none';
icon.src = 'down_arrow.png';
}
}
// -->
</script>
<br>
<img src="down_arrow.png" id="toggle-table">
You've added some extra requirements to your question. You've tagged jQuery and this is the easiest solution for this scenario.
Remove the javascript:sizeTbl() from your <anchor> tag. This is known as inline JS and isn't recommended because it means you are mixing your presentation code with your business logic.
You make the <anchor> tag act like a normal anchor tag and attach a click event in the document's ready event.
function sizeTbl() {
var tbl = document.getElementById('tbl');
var icon = document.getElementById('toggle-table');
if (icon.innerText === 'show') {
tbl.style.display = 'block';
icon.innerText = 'hide';
} else {
tbl.style.display = 'none';
icon.innerText = 'show';
}
}
$(document).ready(function(){
$('#sizeTbl').on('click', sizeTbl);
});
I've created a new jsFiddle that demonstrates this.
Notes:
You need to be using jQuery for this to work
Note that I've given the <anchor> tag an ID. This is so that I can locate it in code
If you have any other comments, the etiquette on SO is to ask new questions. The answers get too long and complicated otherwise

I'm trying to figure out how to add autoscroll till the end of the page/div in 2 different situations as I'm new to JS.
1)When a div is appearing from display:none to block.
For example, here is when my alert appears and I want it to be fully shown. Is there a way to add in a piece of automatic code here? I made it mechanically so far.
document.querySelector('button').onclick = function() {
if(document.querySelector('select').value === "a") {
rightAlert.style.display = 'block';
wrongAlert.style.display = 'none';
window.scrollBy(0, 100);
}
When details/summary are clicked and expanded, with the traditional structure (Details, Summary, P)
Tried
document.querySelector('summary').onclick = function() {
window.scrollBy(0, 100);
};
but it didn't work.
Thanks a lot!
I pretty new at JavaScript & JQuery, more knowledgeable at html & css but I have something I've been working on for days and banging my head to the desk and can't figure it out. Maybe someone could help me, any hint, suggestion would be greatly appreciated!!
I have the following HTML:
<div id="projects" class="fluid">
<button onClick="myFunction2()" class="viewprojectsclose">Close</button>
<button onclick="myFunction()" class="viewprojects">View Projects</button>
<div id="projectsimg">
</div>
<div id="projectstxt">
</div>
</div>
with the following JavaScript and JQuery:
function myFunction() {
document.getElementById("projectstxt").innerHTML = 'some text some text some text';
document.getElementById("projectstxt").style.borderBottom = "thin solid #000" ;
document.getElementById("projectstxt").style.display = "block";
document.getElementById("projectstxt").style.paddingBottom ="10px";
document.getElementById("projectsimg").style.padding = "100px" ;
document.getElementById("projectsimg").style.background = "url('../Assets/img/services/image1.png')" ;
document.getElementById("projectsimg").style.backgroundRepeat = "no-repeat";
document.getElementById("projectsimg").style.backgroundSize = "20%";
document.getElementById("projectsimg").style.display = "block";
document.getElementById("projectsimg").style.transition = "all 0.5s ease-in-out";
document.getElementById("projectsimg").style.backgroundOrigin = "border-box";
document.getElementById("projectsimg").style.marginTop = "5%";
;}
function myFunction2() {
document.getElementById("projectstxt").style.display = "none";
document.getElementById("projectsimg").style.display = "none";
;}
$(document).ready(function()
{
$(".viewprojects").click(function(){
$("#projects").animate({
height:"300px"
});
});
$(".viewprojectsclose").click(function(){
$("#projects").animate({
height:"80px"
});
});
});
Basically we have 2 buttons(OPEN and CLOSE). First opens the image and text DIV and 2nd one closes. What I'm trying to do is add another button below the image(within the div) that will redirect you to a specific page. I can add a regular button in the image DIV in HTML but when it loads the page that button appears on it by default though it should appear only when clicking on the 1st button( and opens the innerHTML). This means that I have to add it somehow in JS. If I press close and reset the div, then the button appears as it should, only when clicking on the 1st OPEN button. I have no idea what is the JS script to prevent from loading the button at first and load it only when I click on the 1st button within the JS.
Any help would be divine!! Thank you in advance!
Yes, there is a conflict because you're over-riding the click handler for your buttons in javascript and jquery. You don't have to do that at all. You should in MHO stick to Jquery and just add the appropriate DOM changes in the click handlers like so:
$(document).ready(function()
{
$(".viewprojects").click(function(){
//Animate first
$("#projects").animate({
height:"300px"
});
//Update DOM
document.getElementById("projectstxt").innerHTML = 'some text some text some text';
document.getElementById("projectstxt").style.borderBottom = "thin solid #000" ;
document.getElementById("projectstxt").style.display = "block";
document.getElementById("projectstxt").style.paddingBottom ="10px";
document.getElementById("projectsimg").style.padding = "100px" ;
document.getElementById("projectsimg").style.background = "url('../Assets/img/services/image1.png')" ;
document.getElementById("projectsimg").style.backgroundRepeat = "no-repeat";
document.getElementById("projectsimg").style.backgroundSize = "20%";
document.getElementById("projectsimg").style.display = "block";
document.getElementById("projectsimg").style.transition = "all 0.5s ease-in-out";
document.getElementById("projectsimg").style.backgroundOrigin = "border-box";
document.getElementById("projectsimg").style.marginTop = "5%";
});
$(".viewprojectsclose").click(function(){
document.getElementById("projectstxt").style.display = "none";
document.getElementById("projectsimg").style.display = "none";
//Animate the div
$("#projects").animate({
height:"80px"
});
});
});
Now, I have just restructured the code that you posted in the question to give you an understanding how to fix it. The code is NOT sanitized and the syntax should be appropriately changed according to Jquery specs for simplicity and ease. It's a simple exercise that you can do on your own.
PS: I have updated the fiddle to incorporate the changes that I just mentioned and it seems to be working fine. Again, I know the Jquery syntax is not appropriate but it's deliberate. Anyway, I hope it gets you started in the right direction. Also, when using javascript and Jquery, stick to one either pure javascript or jquery as you can achieve almost all the functionality that you require her in jquery and it is more versatile and easy to use.
Currently I hide and show the content of a div like this:
var header = null;
var content = null;
var mainHolder = null;
var expandCollapseBtn = null;
var heightValue = 0;
header = document.getElementById("header");
content = document.getElementById("content");
mainHolder = document.getElementById("mainHolder");
expandCollapseBtn = header.getElementsByTagName('img')[0];
heightValue = mainHolder.offsetHeight;
header.addEventListener('click', handleClick, false);
mainHolder.addEventListener('webkitTransitionEnd',transitionEndHandler,false);
function handleClick() {
if(expandCollapseBtn.src.search('collapse') !=-1)
{
mainHolder.style.height = "26px";
content.style.display = "none";
}
else
{
mainHolder.style.height = heightValue + "px";
}
}
function transitionEndHandler() {
if(expandCollapseBtn.src.search('collapse') !=-1)
{
expandCollapseBtn.src = "expand1.png";
}
else{
expandCollapseBtn.src = "collapse1.png";
content.style.display = "block";
}
}
This is fine if the content is static, but I'm trying to populate my div dynamically like so.
This is called from an iphone application and populates the div with a string.
var method;
function myFunc(str)
{
method = str;
alert(method);
document.getElementById('method').innerHTML = method;
}
I store the string globally in the variable method. The problem I am having is now when I try expand the div I have just collapsed there is nothing there. Is there some way that I could use the information stored in var to repopulate the div before expanding it again? I've tried inserting it like I do in the function but it doesn't work.
Does anyone have any ideas?
to replicate:
Here is the jsfiddle. jsfiddle.net/6a9B3 If you type in text between
here it will work fine. I'm not sure
how I can call myfunc with a string only once in this jsfiddle, but if
you can work out how to do that you will see it loads ok the first
time, but when you collapse the section and attempt to re open it, it
wont work.
If the only way to fix this is using jquery I dont mind going down that route.
is it working in other browsers?
can you jsfiddle.net for present functionality because it is hard to understand context of problem in such code-shoot...
there are tonns of suggestions :) but I have strong feeling that
document.getElementById('method')
returns wrong element or this element not placed inside mainHolder
update: after review sample in jsfiddle
feeling about wrong element was correct :) change 'method' to 'info'
document.getElementById('method') -> document.getElementById('info')
I think you want to use document.getElementById('content') instead of document.getElementById('method') in myFunc.
I really see nothing wrong with this code. However, a guess you could explore is altering the line
content.style.display = "none";
It might be the case that whatever is displaying your html ( a webview or the browser itself) might be wiping the content of the elemtns, as the display is set to none
I'm attempting to create a slide out panel that appends to the container div within the header and footer of my page. I'm using Bootstrap for responsive, so the solution should ideally work with the media-queries contained within that package. I'm really at a loss on how to approach this because everything I've tried doesn't seem to work in some way or another.
This picture animates best what I'm trying to accomplish (sorry not a designer):
http://d.pr/i/DzQc+
What I've tried:
Pageslide - this is was the closest solution I've found so far. this appends the slide out panel to the body. As such it doesn't allow me to keep the slide out panel within the header/footer container of the page: http://srobbin.com/jquery-plugins/pageslide/
jQuery Mobile Panel Widget - I tried to hack and repurpose the jQuery mobile panel widget plugin to function as desired without any luck.
.append Function - I tried to animate the .append function but this didn't work with the responsive functions of bootstrap.
With that all said, do any of you have a suggestion on a plugin, function or implementation that may work? I'm not necessarily looking for a working piece of code, rather I'm looking for a direction that will work as I'm hoping.
Thanks!

I'm pretty new to javascript and programming and have run into a brick wall with my project. I have a div which contains the javascript to embed a quicktime player, when the page is first loaded no .mov file is pointed at by the page so a placeholder div is 'unhidden' and the player div is set to style.display = 'none'.
So far so good, the user then enters the name of the new movie, the placeholder div is hidden and the player div is unhidden. My problem is that the javascript in the player div didn't run when the div was made visible, if I make the script for the player into a seperate function then call it when the player div is unhidden then the player runs full screen and not in the div.
I've tried using jquery to add the javascript into the div after the div is made visible but can't seem to get $("#player").load(somescript) or $("#player").html(htmlwithjavain) to add the script.
I know the player div contenst can be changed as I can use $("#player").empty(); and $("#player").html(); to manipulate it.
Thanks for reading, hope you can help
Here's the relevant code:-
<html>
<head>
<title>Browse Media Player</title>
<link rel="stylesheet" type="text/css" href="CSS/browser.css" />
<script type="text/javascript">
<!--
var userinterrupt=false;
var runonce=false;
var currentfile;
var basemediapath = "http://10.255.10.71/IsilonBrowse/movfiles/";
var playerheight = 750;
var playerwidth = 900;
var currenttc;
var basetime;
var baseduration;
var currentduration = "no tc available";
var tcoffset = 35990;
var playspeed = 1;
var boolisplaying=true;
var boolonslide=false;
//function to fire off other methods when the DOM is loaded
//Use in place of body onload, using jquery library
//
$(document).ready(function()
{
//showEvents('jquery running');
showhideplayer(null);
});
//-->
</script>
</head>
<body onload="forceslider(); timecode()">
<div class="container">
<div id="timecode_container">
<div class="tc_overlay"></div>
<div id="timecode" class="timecode"></div>
</div>
<div id="player" class="playerdiv" style="display:none;">
**javascript for player goes here...**
</div>
<div id="noclipoverlay" class="playerdiv" style="display:none;">
<p>No media loaded...

<p>loading media....
</div>
</div>
<div id="loadstatus"></div>
<div id="alerts"></div>
</body>
</html>
Now the mainstuff.js file which should add the javascript code:-
//function to switch the player div and mask div is no media file is
//defined in the 'currentfile' variable
//
function showhideplayer(state)
{
if (!currentfile)
{
showEvents('wtf no media');
document.getElementById("player").style.display = 'none';
document.getElementById("noclipoverlay").style.display = 'block';
}
else if (currentfile)
{
document.getElementById("player").style.display = 'block';
document.getElementById("noclipoverlay").style.display = 'none';
showEvents('valid media file');
}
}
//end of showhideplayer
//function to change movie files, note SetResetPropertiesOnReload must be set to false
//otherwise the B'stard player will default all attributes when setURL runs
//
function changemovie(newmovie)
{
oldfile = currentfile;
if (newmovie == currentfile)
{
showEvents('same file requested so no action taken');
return;
}
if (newmovie != currentfile)
{
showEvents('changing movie');
//switch the divs around to hide the 'no media slide'
document.getElementById("player").style.display = 'block';
document.getElementById("noclipoverlay").style.display = 'none';
}
showEvents('movie changed to: '+newmovie);
currentfile=newmovie;
if (!oldfile)
{
$("#player").empty();
showEvents('the old media file was blank');
$("#player").load("/path/loadplayer.js");
}
document.movie1.Stop();
document.movie1.SetResetPropertiesOnReload(false);
document.movie1.SetURL(currentfile);
//showEvents('movie changed to: '+newmovie);
if (boolisplaying)
{
document.movie1.Play();
}
}
[EDIT] and here's the contents of loadplayer.js:-
var movie1 = QT_WriteOBJECT(
currentfile, playerwidth, playerheight, "",
"controller","false",
"obj#id", "movie1",
"emb#id","qt_movie1",
"postdomevents","True",
"emb#NAME","movie1",
"enablejavascript","true",
"autoplay","true",
"scale","aspect",
"pluginspage","http://www.apple.com/quicktime/download/"
);
Without knowing the content of your loadplayer.js file, it will be difficult to give you a solution.
For example, if the script attempts to do a document.write() after the page has loaded, it will create a new page, overwriting the current page. Is that what you mean when you say the quicktime movie is running full screen?
Also it is generally not a good idea to load a SCRIPT element and insert it as HTML. When you add HTML to the page, jQuery finds all the SCRIPT elements and evaluates them in a global context, which might give you unexpected results.
Use QT_GenerateOBJECTText_XHTML or QT_GenerateOBJECTText from AC_QuickTime.js if you'd like to return a string.
