JavaScript - Need Help With Expand/collapse Toggle Button/icon
I am a beginner with coding and have no idea what I'm doing. Hopefully I'm posting this on the right forum.
I have just registered a domain for my business and am maintaining my webpage through tumblr. I have stumbled around into finding a code that will allow me to hide/collapse certain content. The problem is that I want it to become an icon that changes from a "plus" to a "minus" sign, or any one character to another, as opposed to having it be the title that gets clicked on in order to be expanded. One major issue I'm having revolves around content expanding where a link is displayed. I am coding this on the "links" section of my page, which is links to other businesses and webpages I support. So, for example, I'll have a link to a business, and the hidden content will be something I have to say about it, that the person viewing can chose to read by clicking to expand content. I want it hidden by default to take up less space. This is the code I put into my head section: <!-- COLLAPSIBLE TEXT --> <!-- This goes into the HEAD of the html file --> <script language="JavaScript" type="text/javascript"> <!-- Copyright 2005, Sandeep Gangadharan --> <!-- For more free scripts go to http://www.sivamdesign.com/scripts/ --> <!-- if (document.getElementById) { document.writeln('<style type="text/css"><!--') document.writeln('.texter {display:none} @media print {.texter {display:block;}}') document.writeln('//--></style>') } function openClose(theID) { if (document.getElementById(theID).style.display == "block") { document.getElementById(theID).style.display = "none" } else { document.getElementById(theID).style.display = "block" } } // --> </script> And this is what the html looks like, which I've placed within a table (the list of businesses/pages I support or recommend): <td width=[]> <h2><u>[list name]</u></h2> <p> <a href="http://[link to business].com">[name]</a> <br> <div onClick="openClose('a3')" style="cursor:hand; cursorointer">∇</div> <div id="a1" class="texter"><font style="font-size:90%" color="maroon"> [hidden content]</font></p></div> Is is possible for me to place some kind of code where I have the ∇ that will switch between two icons when shown/hidden? Do I have to use a completely different script? Also, is it possible to keep both a link and a toggle icon on the same line without a break, yet have them lead to different places? Maybe this is more difficult than I think it should be, but I really cant find a good script on the internet for this. Any help would be appreciated. Thanks. Similar TutorialsHello, Can anyone tell me where I can find the code being used here to expand and collapse text(under the Bio section). It's exactly what I am looking for and would be much appreciated. Thanks. Hello everyone, I am just learning the basics of javascript, and am finding myself stuck. Any help is greatly appreciated. So, I'm using the below javascript for expand / collapse text, it suffices well. However it will only collapse either table rows, or table data cells. Now, I know that these tags Code:
{var trs = table.getElementsByTagName('tr');
{var a = trs[i].getElementsByTagName('td')
Make the rows / data cells expand. However, I cannot seem to make it work on headers. To be lucid, I would like to know what I have to add, or edit to make the below code expand table headers (<th>), and perhaps div tags. The full javascript is thus : Code:
window.onload = function()
{
var table = document.getElementById('stjorn');
if (table)
{
var trs = table.getElementsByTagName('tr');
for(var i = 0; i < trs.length; i++)
{
var a = trs[i].getElementsByTagName('td')[0].getElementsByTagName('a')[0];
a.onclick = function()
{
var span = this.parentNode.getElementsByTagName('span')[0];
span.style.display = span.style.display == 'none' ? 'block' : 'none';
this.firstChild.nodeValue = span.style.display == 'none' ? 'More' : 'Less';};
}
}
};
Thank you for your time. Hi, Please find the attached HTML Source Code. I was able to achieve Collapsing/Expand at Project Level but not at the vendor level. However, same HTML works fine with IE 8 and FF. The Expand/Collapse at the Vendor Level fails with XHMTL Strict 1.0 and IE 7. Can any one please help? Thanks Is it possible to have a thumbnail of a video, then when you click it it expands so you can watch it without having to link to a different page? I'm thinking kind of like how people link youtube videos on facebook
I have the following functions: Code: <script>
var timerlen = 5;
var slideAniLen = 500;
var timerID = new Array();
var startTime = new Array();
var obj = new Array();
var endHeight = new Array();
var moving = new Array();
var dir = new Array();
function slidedown(objname){
if(moving[objname])
return;
if(document.getElementById(objname).style.display != "none")
return; // cannot slide down something that is already visible
moving[objname] = true;
dir[objname] = "down";
startslide(objname);
}
function slideup(objname){
if(moving[objname])
return;
if(document.getElementById(objname).style.display == "none")
return; // cannot slide up something that is already hidden
moving[objname] = true;
dir[objname] = "up";
startslide(objname);
}
function startslide(objname){
obj[objname] = document.getElementById(objname);
endHeight[objname] = parseInt(obj[objname].style.height);
startTime[objname] = (new Date()).getTime();
if(dir[objname] == "down"){
obj[objname].style.height = "1px";
}
obj[objname].style.display = "block";
timerID[objname] = setInterval('slidetick(\'' + objname + '\');',timerlen);
}
function slidetick(objname){
var elapsed = (new Date()).getTime() - startTime[objname];
if (elapsed > slideAniLen)
endSlide(objname)
else {
var d =Math.round(elapsed / slideAniLen * endHeight[objname]);
if(dir[objname] == "up")
d = endHeight[objname] - d;
obj[objname].style.height = d + "px";
}
return;
}
function endSlide(objname){
clearInterval(timerID[objname]);
if(dir[objname] == "up")
obj[objname].style.display = "none";
obj[objname].style.height = endHeight[objname] + "px";
delete(moving[objname]);
delete(timerID[objname]);
delete(startTime[objname]);
delete(endHeight[objname]);
delete(obj[objname]);
delete(dir[objname]);
return;
}
</script>
I have the following div tag: Code: <div id='mydiv' style='display:none'>some content</div> ....and then I have an ahref tag like so: Code: <a href="javascript:;" onclick="slidedown('mydiv');">Slide Down</a>
<a href="javascript:;" onclick="slideup('mydiv');">Slide Up</a>
What happens is that it just unhides real quick, and then will not work after that...it does shoot an error, which is 'Invalid argument'...and nothing else. It is craping out on the following line: obj[objname].style.height = d + "px"; not sure why...so if anyone has any insight on what I am doing wrong...please let me know. Hello, Can someone please assist me with making a script work with a 3-tier menu? http://howto.50webs.net/tutorial.php?id=165# Right now, it's only programmed for two. I need to be able to expand like this: + Item ... + Item ...... - Item ...... - Item Here it is in practice: http://golubcapital.com/relaunch/collapse-expand.php If you expand Direct Lending you'll see that Industry Verticals opens already expanded and can't be closed. Thanks in advance for any help. Christine Hey guys. I've done a script where a paragraph expands when the expand button is clicked (plus.gif) and contracts when the same button is clicked again. Only problem is I want the icon to change to a minus icon (minus.gif) once it the paragraph has expanded. I'll obviously need to include this in the script, however I'm not sure how to go about it. Collapsed: Expanded: Here is the HTML: Code: <script type="text/javascript" src="expandCollapse.js"></script>

Any help much appreciated, cheers! Hi everyone I wondered if someone may help me. I downloaded a free web template that I am converting into .tpl file for a php script I use everything is going fine apart from one thing the collapse and expand script for categories in the template, it works perfectly on the template as downloaded but when it is in my .tpl files that work with the php script the collapse expand script works but the images are not displayed when you collapse then when you expand againe the expanded icon is also not displayed, as I say this works perfectly as downloaded in a .html file but not in the .tpl when running the php. Could someone take a look at the coding and tell me what maybe wrong I know nothing about Java script, PHP only a bit about html and I am pulling my hair out. Here is the Java script Bit Code: $('#wrap-categories .expanded').click(function() {
if($("ul#category-menu").css("display") == 'none'){
$('#wrap-categories .expanded').css("background", "url(images/cat-expanded-icon.png) no-repeat center center");
$("ul#category-menu").show();
}
else{
$('#wrap-categories .expanded').css("background", "url(images/cat-collapsed-icon.png) no-repeat center center");
$("ul#category-menu").hide();
}
});
My CSS for the colapsable stuff Code: #wrap-categories .wrap-title-black .expanded{ float: left; width: 40px; height: 40px; background: url(../images/cat-expanded-icon.png) no-repeat center center; }
#wrap-categories .wrap-title-black .collapsed{ float: left; width: 40px; height: 40px; background: url(../images/cat-collapsed-icon.png) no-repeat center center; }
#wrap-categories .wrap-title-black .expanded:hover, #wrap-categories .wrap-title-black .collapsed:hover{ cursor: pointer; }
And finaly the actual .tpl code for the colapsable bit Code: <div id="wrap-categories">
<div class="wrap-title-black">
<h2 class="nice-title">{L_276}</h2>
<div class="expanded"></div>
</div>
<ul id="category-menu">
<!-- BEGIN cat_list -->
<li><a href="browse.php?id={cat_list.ID}">{cat_list.NAME} {cat_list.CATAUCNUM}</a></li>
<!-- END cat_list -->
<li><a href="{SITEURL}browse.php?id=0">{L_277}</a></li>
</ul>
</div>
I would apreciate some help and thank you in advance Hi, I want to make a list that expands and collapses like on the lynda.com site. See example http://www.lynda.com/Rhino-4-tutoria...g/59223-2.html I would also like to make it fade in and out when collapsing and expanding. I haven't been able to find a lot of information on how to do this. Would this be best using something like jQuery or just plain JavaScript? By the way I'm just starting to learn JavaScript, so any level of explanation is helpful. i presently have a text area which is generated using two arrays.It is loaded at the screen load. It is as following. var channelsGroups = new Array(); var channelsChildren = new Array(); channelsGroups[0]= new Array('Mars Public', 'MARS-PUB'); channelsChildren[0]=new Array(); channelsGroups[1]= new Array('Mars Private', 'MARS-PRIVA'); channelsChildren[1]=new Array(); channelsGroups[2]= new Array('Internet Booking Engine', 'IBE'); channelsChildren[2]=new Array(); channelsGroups[3]= new Array('mars Private Agent Specific', 'M-P-AGENT'); channelsChildren[3]=new Array(); channelsChildren[3][0]=new Array('AGT_002',' AGT_002 '); channelsChildren[3][1]=new Array('CARLSON WAGONLIT AUSTRALIA PTY',' 235830 '); channelsChildren[3][2]=new Array('Travel Zone',' TRAVELZONE '); channelsChildren[3][3]=new Array('Worldlink Travels',' WORLDLINK '); channelsChildren[3][4]=new Array('AAAAAAARFDS',' ADM2 '); channelsChildren[3][5]=new Array('AAASSRet',' DMM3 '); channelsChildren[3][6]=new Array('Adrian Travels',' DMM1 '); channelsChildren[3][7]=new Array('Buraha Travels',' DMM2 '); and more Output in the textArea is as following i presently have a text area which is generated using two arrays.It is loaded at the screen load. It is as following. i presently have a text area which is generated using two arrays.It is loaded at the screen load. It is as following. Mars Public Mars Private Internet Booking Engine mars Private Agent Specific -AGT_002 -CARLS... I hope you inderstand the pattern. I want first to display only the groups(Mars Public, Mars Private) and when someone clicks on mars private Agent specific, the list of agents appear. There are other groups below agents and those groups also may have children.Those groups also should have the same on click functioanlity? Any Idea? Thank you in advance... Hey guys I am having little trouble with this jQuery. The code seems to be working in all browsers and suffers only minor issues in IE.

I used the script from this website to create an expanding and collapsing sitemap bar at the bottom of my page.

Hi everyone, I have a set of "buttons" that expand/collapse information onClick, using Javascript that look like this... Here is the CSS I used to create the look of the "buttons"... Code: div.btn_workshops {
background-image: url(../images/btn_workshops_mid.gif);
background-position: top left;
background-repeat: repeat-x;
cursor: pointer;
height: 22px;
margin-bottom: 1px;
width: 330px;
}
div.btn_workshops_lt {
background-image: url(../images/btn_workshops_lt.gif);
background-position: 0 0;
background-repeat: no-repeat;
height: 100%;
width: 100%px;
}
div.btn_workshops_rt {
background-image: url(../images/btn_workshops_rt.gif);
background-position: 100% 0;
background-repeat: no-repeat;
height: 100%;
padding: 3px 12px 0px 12px;
width: 100%px;
}
.hide {
display: none;
visibility: hidden;
}
.show {
display: block;
visibility: visible;
}
Here is the HTML that contains the "buttons" and the text that will appear when you click on the "buttons" to expand them. Keep in mind that everything collapses when you click on any of the "buttons" a second time. This is done, using Javascript. Code: <div class="btn_workshops" onclick="expandWorkshops('workshop1');flipArrow('arrow1')">

Here is the JavaScript I used to create the expand/collapse effect... Code: //Expand Workshops
function expandWorkshops(obj) {
var workshop = document.getElementById(obj)
if ( workshop.className != "hide" )
{ workshop.className = 'hide' }
else { workshop.className = 'show' }
}
Here is my problem. I added the downward, red arrows to give users a "hint" that the "buttons" will do some action if you click on them. By default, I have the arrows facing down to show that information will appear below the "button." Then once a user has expanded a block of information, I want the downward, red arrow to change to an upward, red arrow. I currently have that working, but it is only working "one way." In other words, when you click on any one of the "buttons," the arrow does change, but it does not change back to the default when you click on a "button" a second time to collapse the information. Here is what it looks like with one of the "buttons" expanded. As you can see, I was successfully able to change the downward arrow to an upward arrow after the information expanded below. This helps show that the text can collapse upward if you click on the "button" a second time. Again, my problem is I am unable to get the upward arrow to return to its default, downward arrow appearance. This is what it currently looks like when you click on the "button" a second time to collapse the information. As you can see, my expand/collapse effect works, and the text goes away, but I am unable to get the upward arrow to change back to the default, downward arrow. This is the function that I added to my JavaScript, which successfully changes the arrow from down to up onClick, but fails to return the arrow image to default when you click again. Code: function flipArrow() {
if ( document.images("arrow1").src = "static/images/arrow_down.gif" )
{ document.images("arrow1").src = 'static/images/arrow_up.gif' }
else if ( document.images("arrow1").src = "static/images/arrow_up.gif" )
{ document.images("arrow1").src = 'static/images/arrow_down.gif' }
}
This is the full JavaScript that includes the expand/collapse effect and the unsuccessful swap arrow effect so you can everything together. Code: //Expand Workshops
function expandWorkshops(obj) {
var workshop = document.getElementById(obj)
if ( workshop.className != "hide" )
{ workshop.className = 'hide' }
else { workshop.className = 'show' }
}
function flipArrow() {
if ( document.images("arrow1").src = "static/images/arrow_down.gif" )
{ document.images("arrow1").src = 'static/images/arrow_up.gif' }
else if ( document.images("arrow1").src = "static/images/arrow_up.gif" )
{ document.images("arrow1").src = 'static/images/arrow_down.gif' }
}
The flipArrow function I wrote is just my latest attempt. Believe me, I've tried all kinds of things, including "if else," "if else if," "if." I've tried Variables, getElementById, and switched out all different kinds of methods and ID's. No matter what, I can't seem to get any combination to work. Don't get me wrong. One of the previous methods I tried might have been the correct one, but I most likely did not write it correctly. I am no JavaScript expert at all. The code that I currently have was partly found on the Internet and partly modified by me after hours and hours of research and troubleshooting. I'm very proud that I was able to get this far, but I'm getting to the point where I am spending all day and night, every day, trying to figure this out. I always search forums before posting in them. This is probably the second time I've ever posted in a forum. I hope it helps. Sorry to ramble on. I just want to make sure you have as many details and samples as possible so I do not get any questions or confusion. Thanks for your help!

Hello all, I am currently looking to create a JavaScript menu for a website I am working on. It currently expands and collapses on click. The code in question is pasted below:- menu_status = new Array(); function showHide(theid){ if (document.getElementById) { var switch_id = document.getElementById(theid); if(menu_status[theid] != 'show') { switch_id.className = 'show'; menu_status[theid] = 'show'; }else{ switch_id.className = 'hide'; menu_status[theid] = 'hide'; } } } As you can see, it basically shows and hides the menu (when clicked). I want it to open the menu when clicked and close when another menu is opened. I have looked and have not been able to find a solution into it. Ideally I donot want it to be a long piece of code as I do have a working menu but with many more lines of JavaScript than the one I have posted. I need a solution to it urgently, your help is appreciated. Thanks I have a script that will slide a div up from the bottom of the page. The toggle button for this div however is going to be right on top of the sliding div. But, when the button is pressed and the div starts to slide down, the script hides the button. Here's an example... http://www.codekraken.com/dashpad/testing/test2.html How can I get the toggle button to slide with it, but not disappear? I'm trying to make a page where you can change a page's layout through 2 separate CSS's via a button. i want to button to change text when it toggles the layouts as well. i have no clue how to do this with an entire CSS file, but here is something i made to change the background. could i use this logic to change the CSS of a page? HTML <in Code: <input type="button" value="change layout" onclick="toggle()" /> JavaScript Code: var flag = 0; function toggle(){
if(flag==0){
document.getElementById("container").style.backgroundImage="blah.jpg";
flag=1; } else if(flag==1){
document.getElementById("container").style.backgroundImage="blah2.jpg";
flag=0; } }
