JavaScript - Expandable Groups
Hi, I'm completely new to using JavaScript having never used it before so please forgive me if this is ridiculously easy to solve.
I want to include an expandable FAQ section in part of my website. I managed to find some code that works however by default the sections are expanded. I want them to automatically be collapsed when the page loads and when you click the image it then expands and shows the hidden text. The code I found is Code: <head><title> Untitled Page </title> <script type="text/javascript"> function expandable_toggle(id) { var tr = document.getElementById(id); if (tr==null) { return; } var bExpand = tr.style.display == ''; tr.style.display = (bExpand ? 'none' : ''); } function expandable_changeimage(id, sMinus, sPlus) { var img = document.getElementById(id); if (img!=null) { var bExpand = img.src.indexOf(sPlus) >= 0; if (!bExpand) img.src = sPlus; else img.src = sMinus; } } function Toggle_trGrpHeader1() { expandable_changeimage('trGrpHeader1_Img', 'images/minus.gif', 'images/plus.gif'); expandable_toggle('trRow1'); } function Toggle_trGrpHeader2() { expandable_changeimage('trGrpHeader2_Img', 'images/minus.gif', 'images/plus.gif'); expandable_toggle('row1'); } </script> </head> <body> <div> <table border="0"> <tr id="trGrpHeader1"> <td colspan="4"><span onclick="javascript:Toggle_trGrpHeader1();"><img src="images/minus.gif" id="trGrpHeader1_Img"/>Pretend this is a header for row 1</span></td> </tr> <tr id="trRow1"> <td> Hello<br><br></td></tr> <tr id="trGrpHeader2"><td colspan="4"><span onclick="javascript:Toggle_trGrpHeader2();"><img src="images/minus.gif" id="trGrpHeader2_Img"/>Pretend this is a header</span></td> </tr> <tr id="row1"> <td> 123</td></tr> </table> </div> </body> </html> Any help you can give would be greatly appreciated. Many thanks Similar TutorialsI just got this problem when I try to add the expandable divs in my webpage. However when I click the divs on the page, I can't see the rest of my content. This is my page, does anybody know what happened with my code??!! http://www.calibredesign.com/clients..._news_new.html the divs are on the button of the page. Thanks!! Hey guys, I own an online internet radio station and I have many different way which people can tune in. One way is the browse 'n' play feature. The browse 'n' play feature allows you to browse the net at the same time as being tuned into the radio. Below, I have installed an 'Expandable Sticky Bar' which is used for the radio panel. http://www.dynamicdrive.com/dynamici.../stickybar.htm What I am trying to do, is simply add that bar on every page my visitors visit. So, when the listen chooses 'Browse 'n' Play' I want a new window or tab to open, with Google and my bar at the bottom. I cannot figure out how I could do this, any ideas on how I could make this happen? Thanks. hi, i got a expandable menu that is working. i wonder if there is any way to make the links show as html and css if the user has disabled javascript i my code including javascript and css <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> <script language="JavaScript" type="text/JavaScript"> <!-- 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'; } } } //--> </script> <style type="text/css"> .menu1{ margin-left:25px; padding-left:20px; padding-top:2px; padding-bottom: 2px; display:block; text-decoration: none; color: #000000; height: 20px; width: 200px; background-color: #03C; border: thin solid #FFF; } .submenu{ background-image: url(images/submenu.gif); display: block; height: 19px; margin-left: 38px; padding-top: 2px; padding-left: 7px; color: #333333; } .hide{ display: none; } .show{ display: block; } </style> </head> <body> <a class="menu1" onclick="showHide('mymenu1')">Menu 1</a> <div id="mymenu1" class="hide"> <a href="#" class="submenu">Link One here</a> <a href="#" class="submenu">Link Two here</a> <a href="#" class="submenu">Link Three here</a> <a href="#" class="submenu">Link Four here</a> </div> <a class="menu1" onclick="showHide('mymenu2')">Menu 2 </a> <div id="mymenu2" class="hide"> <a href="#" class="submenu">Link One here</a> <a href="#" class="submenu">Link Two here</a> <a href="#" class="submenu">Link Three here</a> <a href="#" class="submenu">Link Four here</a> </div> <a class="menu1" onclick="showHide('mymenu3')">Menu 3 </a> <div id="mymenu3" class="hide"> <a href="#" class="submenu">Link One here</a> <a href="#" class="submenu">Link Two here</a> <a href="#" class="submenu">Link Three here</a> <a href="#" class="submenu">Link Four here</a> </div> <a class="menu1" onclick="showHide('mymenu4')">Menu 4 </a> <div id="mymenu4" class="hide"> <a href="#" class="submenu">Link One here</a> <a href="#" class="submenu">Link Two here</a> <a href="#" class="submenu">Link Three here</a> <a href="#" class="submenu">Link Four here</a> </div> <a class="menu1" onclick="showHide('mymenu5')">Menu 5 </a> <div id="mymenu5" class="hide"> <a href="#" class="submenu">Link One here</a> <a href="#" class="submenu">Link Two here</a> <a href="#" class="submenu">Link Three here</a> <a href="#" class="submenu">Link Four here</a> </div> </body> </html> Hello, I'm pretty new to JS but I can script a few things. I'm using a pre-written script, but trying to add a functionality that uses my + and - images to indicate whats whether the list is expanded or not. It works on the first click. The symbol starts as a plus, you click it and it expands and goes to minus. After that the list maintains functionality (for the most part) but doesn't continue changing symbols back and forth. I've pored over the script for HOURS but I can't find the solution. Working Link Example My written JS: Code: // JavaScript Document var expandables = new Array(); expandables[0] = "expand_northeast"; expandables[1] = "expand_southeast"; expandables[2] = "expand_midwest"; expandables[3] = "expand_southwest"; expandables[4] = "expand_west"; var clickCounter = 0; function expand(current) { //add height to the containing div if(clickCounter<=1) { var newHeight = document.getElementById('region_us').offsetHeight + 187; document.getElementById('region_us').style.height = newHeight.toString() + 'px'; clickCounter+=1; } //get the section name var section = current.split('_')[1]; for ( var i=0; i<expandables.length; i++ ){ if(document.getElementById(expandables[i]).id.indexOf('collapse') != -1){ //if it has collapse in id string var tempSection = expandables[i].split('_')[1]; //parse just the region document.getElementById(expandables[i]).id='expand_' + tempSection; //change the id to expand / plus symbol expandables[i] = document.getElementById('expand_' + tempSection).id; //make the change in the array as well } } document.getElementById(current).href='javascript:animatedcollapse.show(\'stats_'+ section + '\');'; document.getElementById(current).onclick=function() {collapse('\'collapse_'+section +'\'');}; document.getElementById(current).id="collapse_" + section + ""; for (x in expandables) { if(expandables[x] == current){ expandables[x] = document.getElementById('collapse_' + section).id; } } //alert(expandables); } function collapse(current) { var section = current.split('_')[1]; //alert(current); current = ("expand_"+section); document.getElementById(current).href='javascript:animatedcollapse.hide(\'stats_'+ section + ');'; document.getElementById(current).onclick=function() {expand('"expand_'+section+'"');}; document.getElementById(current).id='expand_' + section; for (x in expandables) { if(expandables[x] == current){ expandables[x] = document.getElementById('expand_' + section).id; } } } Relevant HTML: Code: <a id="expand_northeast" href="javascript://" onclick="expand('expand_northeast');"></a> <span class="state_title">Northeast</span> <span class="state_title_num">2,749</span> <span class="state_title_perc">62.5%</span> <div id="stats_northeast" style="display:none;"> <span class="state colored">Maine</span><span class="stat_num colored">32</span><span class="stat_percent colored">7.1%</span><br /> <span class="state">New Hampshire</span><span class="stat_num">32</span><span class="stat_percent">7.1%</span><br /> <span class="state colored">Rhode Island</span><span class="stat_num colored">32</span><span class="stat_percent colored">7.1%</span><br /> <span class="state">New Hampshire</span><span class="stat_num">32</span><span class="stat_percent">7.1%</span><br /> <span class="state colored">Rhode Island</span><span class="stat_num colored">32</span><span class="stat_percent colored">7.1%</span><br /> <span class="state">New Hampshire</span><span class="stat_num">32</span><span class="stat_percent">7.1%</span><br /> <span class="state colored">Rhode Island</span><span class="stat_num colored">32</span><span class="stat_percent colored">7.1%</span><br /> <span class="state">New Hampshire</span><span class="stat_num">32</span><span class="stat_percent">7.1%</span><br /> <span class="state colored">Maryland</span><span class="stat_num colored">32</span><span class="stat_percent colored">7.1%</span><br /> <span class="state">Pennsylvania</span><span class="stat_num">32</span><span class="stat_percent">7.1%</span><br /> </div> Thanks guys! Hi! I have a website that requires preloading images a lot. I would like to preload only the most important images first and display the page as quickly as possible. After that it will take at least 20 seconds before the user will need the rest of the images. Is there a way of making two preloading groups and have the second group load in background after the page is already visible? My current preload code is simply like this: <SCRIPT language="JavaScript"> if (document.images) { pic01= new Image(200,200); pic01.src="images/base.jpg"; pic02= new Image(200,200); pic02.src="images/grump1.jpg"; pic03= new Image(200,200); pic03.src="images/grump2.jpg"; pic04= new Image(200,200); pic04.src="images/grump3.jpg"; pic05= new Image(200,200); pic05.src="images/grump4.jpg"; pic06= new Image(200,200); pic06.src="images/love.jpg"; pic07= new Image(200,200); pic07.src="images/smile1.jpg"; pic08= new Image(200,200); pic08.src="images/smile2.jpg"; pic09= new Image(200,200); pic09.src="images/smile3.jpg"; pic10= new Image(200,200); pic10.src="images/smile4.jpg"; pic10= new Image(200,200); pic10.src="images/rotate.gif"; } </SCRIPT> I want to create a link which doesn't takes you to anew page but just expands to show it's information . Exactly like the one in FAQs where you click the question and the page expands to show you the answer.
I am building an elearning site where the user is taken through a series of dynamically driven pages to refine their choices. I am using php amd mysql to populate a series of tables but on the last page the table gets very long so i am trying to make the table expandable. I found this and this on http://www.javascripttoolbox.com/jquery/ and it's proving helpful but i need a little help taking it a step further. I also found this to be useful for anyone else who is trying to do the same thing: http://www.jankoatwarpspeed.com/post...nd-plugin.aspx FROM JAVASCRIPTTOOLBOX A common UI is to have a table of data rows, which when clicked on expand to show a detailed breakdown of "child" rows below the "parent" row. The only requirements a 1. Put a class of "parent" on each parent row (tr) 2. Give each parent row (tr) an id 3. Give each child row a class of "child-ID" where ID is the id of the parent tr that it belongs Original code: Code: $(function() { $('tr.parent') .css("cursor","pointer") .attr("title","Click to expand/collapse") .click(function(){ $(this).siblings('.child-'+this.id).toggle(); }); $('tr[@class^=child-]').hide().children('td'); }); This works great but my parent and child rows all contain checkboxes and If i try and check the checkboxes in the master rows the child rows associated with that master row expand and contract. I have added an extra cell to each row and i'm using a css class to add an arrow image to each master row but i am new to Javascript so i am not sure what i am doing. My code now looks like this: Code: $(document).ready(function() { $('tr:not(.parent)').hide(); //$('tr.parent') $('.arrow') .css("cursor","pointer") .attr("title","Click to expand/collapse") .click(function(){ $(this).siblings('.child-'+this.id).toggle(); $(this).toggleClass("up"); }); }); So far the arrow image is toggling but i can't seem to work out how to get the .click function to affect the whole row and not just the image. Can anybody help me? Thanks Trying to put my finger on how to achieve this result. About half way down on the page linked below you'll see "Recent - Comments - Popular - Tags" this table expands when you rollover and stays expanded while allowing you to populate the different content. Any help would be greatly appreciated, not even sure if I'm in the right forum. http://thedailydisney.com/blog/2010/...magic-kingdom/ Thanks for the time. Will Hello, I was wondering whether it is possible to expand and collapse forum categories using JavaScript. The forum board I am using is phpBB. Hi guys! I need your help so much. I have this beautiful script for pocket pc that randomly rotates pictures in the background with fade in/out effect. Now, what I want it to do is to split all the pictures I have in groups so that on every refresh the script randomly chose a GROUP of pictures and THEN rotated only the pictures from this group. I want to do this because if you include say 30 pictures into the script this really hangs the RAM memory, and if there are only 5 pictures to choose from its much more faster. Here's the script from html page: Code: <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/> <style> body { background-color: white; margin: 0; padding: 0; } img { -webkit-transition-property: opacity; -webkit-transition-duration: 3s; position: absolute; width: 320px; height: auto; } img.fade-out { opacity: 0; } img.fade-in { opacity: 1; } </style> </head> <body style="color: black"> <img src="01.jpg"/> <img src="02.jpg"/> <img src="03.jpg"/> <img src="04.jpg"/> <img src="05.jpg"/> <img src="06.jpg"/> <img src="07.jpg"/> <img src="08.jpg"/> <img src="09.jpg"/> <img src="10.jpg"/> <img src="11.jpg"/> <img src="12.jpg"/> <img src="13.jpg"/> <img src="14.jpg"/> <img src="15.jpg"/> <script> var interval = 4 * 1; // Seconds between change var images = document.getElementsByTagName("img"); var imageArray = []; var imageCount = images.length; var current = 0; var randomize = function(){ return (Math.round(Math.random() * 3 - 1.5)); } for(var i = 0; i < imageCount; i++){ images[i].className = 'fade-out'; imageArray[i] = images[i]; } imageArray.sort(randomize); var fade = function(){ imageArray[current++].className = 'fade-out'; if(current == imageCount){ current = 0; imageArray.sort(randomize); } imageArray[current].className = 'fade-in'; setTimeout(fade, interval * 1000); }; fade(); </script> </body> So here you can see there are 15 pictures, what should I include in this script to split them into say 3 groups of 5 pictures and make the script randomly select a group each time? Thanks for help! Im new to javascript and was hoping someone could help me with my problem. I have a form that has multiple radio button groups and i want it to validate so that if any button is selected in one group you cannot make a selection in the other groups. any advice would be appreciated Hi, I have a web form that I'm creating and it has some expandable checkboxes that need to be restricted based on choice. This is my criteria: If someone chooses checkbox number 1, they cannot choose any other checkbox. If someone chooses checkbox number 2, they may also choose number 3 but not 1 or 4, they must also answer the question that appears below. If someone chooses checkbox number 3, they may also choose number 2 but not 1 or 4, they must also answer the question that appears below. If someone chooses checkbox number 4, they cannot choose any other checkbox, and must answer the questions that appears below. One more caveat: If checkbox number 2 is chosen, and they've filled in all three lines of the question below, I need for them to dynamically add more lines as needed. I have attached my web form so you can see what I've done. I've researched these options and tried code from various examples but I can't seem to get it to work. Does anyone know how to accomplish all of this? Thank you in advance! The problem: I can't get the code to send out my alerts due to empty radio groups. what I'm trying to accomplish: I want Javascript to send a alert to the user if none of the radio buttons within a group are checked. Short Summary: I'm new to Javascript and I've been trying to figure this out myself, but I honestly don't know what's wrong. If you guys can help that'd be great. Thanks in advance. and if the information that I've provided is in anyway confusing let me know and I'll try to help, but again my knowledge is limited. Here is a simplified version of my form.*There are originally 10 questions total.

There are two navigational elements to the website I'm building and I'm using Spry to do it. I have a horizontal header menu and vertical main menu. Both menus must load their content in the same content area. I've tried a ton of things and I can't get them to work without breaking anything. Here is the basic Spry code. Any help would be very much appreciated. Thanks!! Code: <div id="TabbedPanels1" class="TabbedPanels"> <ul class="TabbedPanelsTabGroup"> <li class="TabbedPanelsTab" tabindex="0">Tab 1</li> <li class="TabbedPanelsTab" tabindex="0">Tab 2</li> </ul> <div class="TabbedPanelsContentGroup"> <div class="TabbedPanelsContent">Content 1</div> <div class="TabbedPanelsContent">Content 2</div> </div> </div> <script type="text/javascript"> <!-- var TabbedPanels1 = new Spry.Widget.TabbedPanels("TabbedPanels1"); //--> </script> The CSS and Jscript files are attached. if you start composing a new message in google groups http://groups.google.com/ and then click the back button a window appear that looks like a javascript confirm popup, however instead of the "OK" "Cancel" buttons, the buttons show a custom wording "Leave this page" "Stay on this page". Anyone knows how do they do that in javascript? Hey thanks in advance to anyone who can take a peak at my code and hopefully point me in the correct direction. I have been working on my final project in my javascript class for a bit, and there are a few erros I cant seem to find through firebug or error console. It is due this evening at midnight, so anyone that could help, I really need this assignment for a decent grade. Basically there are two issues so far, one needs to be solved so the other can be as well. First, line 103 - 105 should create a hyperlink to the specified id, but is doesn't return a number. so the link goes no where it is this code: PHP Code: //create hypertext link to the section heading var linkItem = document.createElement("a"); linkItem.innerHTML = n.innerHTML; linkItem.href = "#" + n.id; Next I belive there is a problem with the function expandCollapseDoc(), that might fix itself when the other problem is solved. The document should expand and collapse with the menu. Here is my javascript code: PHP Code: /* New Perspectives on JavaScript, 2nd Edition Tutorial 7 Tutorial Case Author: Mike Cleghorn Date: 2-15-10 Filename: toc.js Global Variables: sections An array contain the HTML elements used as section headings in the historic document Functions List: addEvent(object, evName, fnName, cap) Adds an event hander to object where evName is the name of the event, fnName is the function assigned to the event, and cap indicates whether event handler occurs during the capture phase (true) or bubbling phase (false) makeTOC() Generate a table of contents as a nested list for the contents of the "doc" element within the current Web page.
