JavaScript - Expandable Checkboxes Restricted Based On Choice
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! Similar TutorialsOk so I have a select box where the value must be passed via the form. If the users selects choice B or Choice C then I want a specific div to show. If they choose choice A then I want the div to hide or remain hidden. It should be hidden on page load. Code: <select name="Event_Type_ID">
<option value="1">Choice A</option>
<option value="2">Choice B</option>
<option value="3">Choice C</option>
</select>
<div id="showme">
Content to show if EITHER Choice B or C is chosen. Otherwise this div should be hidden.
</div>
Can anyone lead me in the right direction? Thanks! I am facing an issue where a link on my website opens in a new window if you simply click on it. However, if you right click and say open in new window or new tab, it opens the same window (URL) again from where the link is clicked. Self Service Option is a link and the JSP calls a function getSelfServSite() when the link is clicked. This is how the code flows in my case function getSelfServSite() { getToTheLink("${myConfigInfo.selfServiceURL}"); // this is because the URL is configurable } function getToTheLink(url) { window.open (url, "currentWindow", ""); } What am I doing wrong. I want it to go to the right link no matter how the user click it. Please advise. Thanks I have a radio button that asks Does your URL exist or need to be purchased? and a drop down menu that lists different types of web projects (i.e. new website and website redesign). What I'm trying to achieve is, if the user selects that the URL exists, I would like the drop down menu option new website to be removed from the list. Form: Code: <form> <input type="radio" name="website_status" value="exists"/> Exists <input type="radio" name="website_status" value="purchase_required"/> Needs to be purchased <select name="projects"> <option></option> <option value="new_website">New Website</option> <option value="website_redesign">Website Redesign</option> </select> </form> JavaScript: [CODE] <script> window.onload = initForms; function initForms() { for (var i=0; i<document.forms.length; i++) { document.forms[i].onsubmit = function() {return validForm();} } } function validForm() { var inputarray = document.getElementsByTagName("input"); var selectarray = document.getElementsByTagName("select"); var textarea = document.getElementsByTagName("textarea"); if (inputarray[0].checked == true) { selectarray[0].remove(options[1]); return false; } </script> I've been experimenting with this for the last couple hours and am getting nothing! Could someone please point me in the right direction? What I would like to do is have a page with a dropdown menu, and depending on which option the user chooses from the dropdown, reload the page and display a particular iframe below the dropdown, based on the users choice. Also, a default iframe would load (the one connected to the default choice in the select box). Hopefully that makes sense. I was trying to make this work with PHP (without having the user having to click a submit button) but I couldn't find a way to make it happen.
This relates to FireBugLite. Can anyone tell me why this happens and how to change what so I can see the code. HTML, CSS and DOM tabs work OK. All are local files except for FireBugLite Thanks I am using XMLHTTPRequest to invoke a url from my web page. I am running in Firefox 3.0 and am getting 'Access to restreicted URI denied' error. The domain of my page is 'serverorta' while the url I'm trying to invoke is 'serverortb'. In both urls the server name is the same, but the port numbers are different. Is there a solution to this issue?

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');

Any help you can give would be greatly appreciated. Many 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. 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;
}
}
}

Thanks guys! 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 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 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.
Hello, I was wondering whether it is possible to expand and collapse forum categories using JavaScript. The forum board I am using is phpBB. 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. Store the nested list in the "toc" element. levelNum(node) Returns the level number of the object node. If the object node does not represent a section heading, the function returns the value -1. createList() Goes through the child nodes of the "doc" element searching for section headings. When it finds a section heading, a new entry is added to the table of contents expandCollapse() Expands and collapse the content of the table of contents and the historic document expandCollapseDoc() Goes through the child nodes of the "doc" element determining which elements to hide and which elements to display isHidden(object) Returns a Boolean value indicating whether object is hidden (true) or not hidden (false) on the Web page by examining the display style for object and all its parent nodes up to the body element */ function addEvent(object, evName, fnName, cap) { if (object.attachEvent) object.attachEvent("on" + evName, fnName); else if (object.addEventListener) object.addEventListener(evName, fnName, cap); } addEvent(window, "load", makeTOC, false); var sections = new Array("h1","h2","h3","h4","h5","h6"); var sourceDoc; //document on which TOC is based on function makeTOC(){ var TOC = document.getElementById("toc"); TOC.innerHTML = "<h1>Table of Contents</h1>"; var TOCList = document.createElement("ol"); TOC.appendChild(TOCList); sourceDoc = document.getElementById("doc"); //generate list items containing section headings createList(sourceDoc, TOCList); } function levelNum(node) { for (var i = 0; i < sections.length; i++) { if(node.nodeName == sections[i].toUpperCase()) return i; } return -1; //node is not section heading } function createList(object, list) { var prevLevel = 0; //level of the pervious TOC entry var headNum = 0; //running count of headings for (var n = object.firstChild; n != null; n = n.nextSibling) { //loop through all nodes in object var nodeLevel = levelNum(n); if (nodeLevel != -1) { //node represents a section heading //insert id for the section heading if necessary headNum++; //create list item to match var listItem = document.createElement("li"); listItem.id = "TOC" + n.id; //create hypertext link to the section heading var linkItem = document.createElement("a"); linkItem.innerHTML = n.innerHTML; linkItem.href = "#" + n.id; //append the hypertext to the list entry listItem.appendChild(linkItem); if (nodeLevel == prevLevel) { //append the entry to the current list list.appendChild(listItem); } else if (nodeLevel > prevLevel) { //append entry to new nest list var nestedList = document.createElement("ol"); nestedList.appendChild(listItem); list.lastChild.appendChild(nestedList); //add plus/minus box beffore the text var plusMinusBox = document.createElement("span"); plusMinusBox.innerHTML = "--"; addEvent(plusMinusBox, "click", expandCollapse, false) nestedList.parentNode.insertBefore(plusMinusBox, nestedList.previousSibling); list = nestedList; prevLevel = nodeLevel; } else if (nodeLevel < prevLevel) { //append entry to a higher-level list var levelUp = prevLevel - nodeLevel; for (var i = 1; i<= levelUp; i++) {list = list.parentNode.parentNode;} list.appendChild(listItem); prevLevel = nodeLevel; } } } } function expandCollapse(e) { var plusMinusBox = e.target || event.srcElement; var nestedList = plusMinusBox.nextSibling.nextSibling; //Toggle the plus and minus symbol if (plusMinusBox.innerHTML == "--") plusMinusBox.innerHTML = "+" else plusMinusBox.innerHTML = "--"; //Toggle display of nested list if(nestedList.style.display == "none") nestedList.style.display = "" else nestedList.style.display = "none"; //expand/collapse doc to match TOC expandCollapseDoc(); } function expandCollapseDoc() { var displayStatus = ""; for (var n = sourceDoc.firstChild; n != null; n = n.nextSibling) { var nodeLevel = levelNum(n); if (nodeLevel != -1) { //determain display status of TOC entry var TOCentry = document.getElementById("TOC" + n.id); if (isHidden(TOCentry)) displayStatus = "none" else displayStatus = ""; } if (n.nodeType == 1) { //apply to current status for the node n.style.display = displayStatus; } } } function isHidden(object) { for (var n = object; n.nodeName != "BODY"; n = n.parentNode) { if (n.style.display = "none") return true; } return false; } the html was too long, so i uploaded it to my webspace you can check out the almost working version at http://www.kinetic-designs.net/final/usconst.htm Again thank you so much! Any questions just ask! I've got a form that performs a calculation upon submit. I want it to perform a different calc depending on the choice from a drop down box in the form. Are there any examples of this? or can someone explain how i do it? thanks Is an iframe the only way to embed a web page? I would like to embed a web page within a email but some users email clients do not support iframes.
