JavaScript - Javascript Cascading Drop Down Menu With 4 Hierarchical Boxes
Hey, so I'm a complete javascript newbie and am trying to create a drop down menu with four different boxes. The site I'm working on is basically an ecommerce site, so I'll use cars as a good example for what I want to do.
Let's say that I'm selling cars and want to target the buyer directly, then I would have the following boxes, each one serving as a dependent of the one before it: 1. Pick the brand (BMW, Mercedes, Etc.) 2. Pick the type of car (Sports car, SUV, Mini Van, etc.) 3. Pick the color (blue, green, etc.) 4. Pick the price ($0-$19,999/$19,999-29,999/etc.) So far I have the first two boxes down by using the following site: http://www.supertom.com/menugen/. Now my problem is that the site only allows for the first two boxes to be made, and says that "the values in box1 are static and printed directly as normal HTML. The corresponding box2 options will also be copied into the HTML as well as the javascript for full functionality." Being a complete newbie, I have no idea what this means. So I decided to search the internet for an answer and was not able to find one, thus leading me here, which from the looks of it seems like a great forum. If anyone could tell me how to connect a third and fourth box that falls into the same hierarchy as the first and the second then I would appreciate. Really THANK YOU, and I'm really looking forward to reading your replies!! -Bobby Similar TutorialsOkay everyone, new here, of course, and as much as I hate to be one of those people that don't really know much about a topic at hand and gratuitously seek out the help of those who do, here I am. The upshot is that it's probably something really easy to answer for those who know Javascript already. I've tried figuring this out but I'm at a loss. I can manage pretty well with CSS, messing around and playing with values to figure out what I need, but I've taken a look at the Javascript and it's completely unapproachable for me. I used a website, http://www.mycssmenu.com/ to create a really nifty dropdown menu, which has a tree structure in Javascript as well as collapse and expand buttons. The great thing is that, for those with Javascript disabled, it still fully works as a CSS drop-down menu. But I've been asked to modify it. Right now, you click and that's how things expand. But I've been asked to make it so that it will expand simply on hover.And I don't know what to do at all. Of course I know how to change the colors of the particular fields when you hover, through CSS, but to make it expand simply on hover? Think anyone can give me some pointers or a bit of help? The website in question is here Psiholog Popa Anca. Great job on the colors though, eh? Let me know! I am trying to create 2 different drop down menus which are chained. First drop down menu: options 1, 2, 3, and 4 Second drop down menu: options 1, 2, 3 and 4 However for the first drop down menu, if you choose the number then that number cannot be selected again on the second drop down menu. So if i pick 4 on the first drop down. then only 1, 2, and 3 should show up on the second drop down OR if you pick 4 on the second drop down it gives you an error saying you selected that value. Here is the complicated part that I cannot figure out. I want each drop down menus on two different pages and not on the same page. So after you select the submit button on the first drop down it should go to another page with the second drop down.. Has anyone seen this before. if you can give me some tips or show me how its done or even a webpage that has already implemented this i would appreciate it. Thank you! I'm sorry if this question might have already been posted before, but as I do not know how to go about phrasing the questions(due to low calibre in technical terms), I could not do any search about it. Basically what I intended to do is to add a *drop down list* to the header looking something like this http://www.w3schools.com/DHTML/tryit...rydhtml_menu10 except for the fact that the header(the Tutorials, Scripting, Validation coloured in pink) isn't coded using .html but .js(in this website, its coded in html as shown below). <html> <head> <style> body{font-family:arial;} table{font-size:80%;background:black} a{color:black;text-decoration:none;font:bold} a:hover{color:#606060} td.menu{background:lightblue} table.menu { font-size:100%; position:absolute; visibility:hidden; } </style> <script type="text/javascript"> function showmenu(elmnt) { document.getElementById(elmnt).style.visibility="visible"; } function hidemenu(elmnt) { document.getElementById(elmnt).style.visibility="hidden"; } </script> </head> <body> <h3>Drop down menu</h3> <table width="100%"> <tr bgcolor="#FF8080"> <td onmouseover="showmenu('tutorials')" onmouseout="hidemenu('tutorials')"> <a href="/default.asp">Tutorials</a><br /> <table class="menu" id="tutorials" width="120"> <tr><td class="menu"><a href="/html/default.asp">HTML</a></td></tr> <tr><td class="menu"><a href="/css/default.asp">CSS</a></td></tr> <tr><td class="menu"><a href="/xml/default.asp">XML</a></td></tr> <tr><td class="menu"><a href="/xsl/default.asp">XSL</a></td></tr> </table> </td> <td onmouseover="showmenu('scripting')" onmouseout="hidemenu('scripting')"> <a href="/default.asp">Scripting</a><br /> <table class="menu" id="scripting" width="120"> <tr><td class="menu"><a href="/js/default.asp">JavaScript</a></td></tr> <tr><td class="menu"><a href="/vbscript/default.asp">VBScript</a></td></tr> <tr><td class="menu"><a href="default.asp">DHTML</a></td></tr> <tr><td class="menu"><a href="/asp/default.asp">ASP</a></td></tr> <tr><td class="menu"><a href="/ado/default.asp">ADO</a></td></tr> </table> </td> <td onmouseover="showmenu('validation')" onmouseout="hidemenu('validation')"> <a href="/site/site_validate.asp">Validation</a><br /> <table class="menu" id="validation" width="120"> <tr><td class="menu"><a href="/web/web_validate.asp">Validate HTML</a></td></tr> <tr><td class="menu"><a href="/web/web_validate.asp">Validate XHTML</a></td></tr> <tr><td class="menu"><a href="/web/web_validate.asp">Validate CSS</a></td></tr> <tr><td class="menu"><a href="/web/web_validate.asp">Validate XML</a></td></tr> <tr><td class="menu"><a href="/web/web_validate.asp">Validate WML</a></td></tr> </table> </td> </tr> </table> <p>Mouse over these options to see the drop down menus</p> </body> </html> So how can I code this in .js instead of .html? I really need a clue on how to get started on coding this as this is totally new to me, hope that anyone would appreciate helping me and I will be grateful about it. Hi everyone, How can I achieve this? I need to get my drop down menu go over the javascript slideshow going on in this page: www.kimikal.com/store It works on all browsers except for IE, which hides the menu behind the js slideshow. Any help would be greatly appreciated! Hi guys. I have been scowering high and low for code to create a Java drop down menu bar for my site. I want it to be something like this: http://javascript-array.com/scripts/...rop_down_menu/ but want to insert pictures into it, for each heading, to create a new looking bar if thats possible. Can you do a mouseover with them also, as i currently have one set up, to change text colour (2 different images per button) but am unsure of the code. Thanks in advance. I've been running into a brick wall on this problem, and have gone over my html, css and PHP dozens of times, so I'm thinking it's a Javascript issue (where my skills are lacking). I'm using a drop-down menu script that I got he http://www.php-development.ru/javascripts/dropdown.php, which I have modified slightly to eliminate timeout and change styles on closing the menu (by clicking on it). It works fine everywhere except in IE 6 and 7. In IE 7, the menu appears where it should, but looks blank. If you leave the sub-menu open and hover over another link, the menu appears as it should. Both drop-down menus do this. In IE6, the problem is similar, except that only the bottom border of the menu items appear, not the whole link. The page can be found he http://www.georgekoury.com/index_test.php, and the only options with drop-down are "Individual Insurance" and "Group Insurance". I realize the code isn't entirely compliant, I inherited this code from another programmer and I'm trying to avoid having to rewrite the whole structure. I'm not sure what code you may need me to post, so if more information is needed, please let me know and I'll provide it. hi im new to scripting so apologies if this is a basic question. I have a form which has javascript validation which triggers hidden divs if certain input boxes are left blank. I have it working with text fields and text areas, but im having trouble with a drop down menu. This is the code for my drop down: Code: <select name="department" size="1" id="department"> <option value="" selected>Please select</option> <option value="1">Personal Injury</option> <option value="2">ULR & Credit Hire</option> <option value="3">Consumer Credit</option> <option value="4">Health & Safety</option> <option value="5">Property</option> </select> And this is the code currently for the Javascript validating: Code: if(department.selectedIndex == 0){
var error = true;
$('#department_error').fadeIn(500);
}else{
$('#department_error').fadeOut(500);
If i leave the drop down on the 'Please Select' value, the error message should show, but at the moment it doesnt show up. I have a feeling the syntax is wrong in the javascript? Any help very much appreciated Thanks I am trying to create a drop down menu for dates that starts with today's date, but allows people to choose 50 years into the past and 10 years into the future.

I am also having a problem with the month. I wanted it to show the name of the month, but I am getting a number (and a wrong one at that). Apologies... I am a terrible newbie with Javascript. Hi guys, I am having an issue changing a piece of Javascript and hoped you guru's could help?I am not awful with Javascript but it is fair to say I am still at the beginning of my learning! I can't find the correct answer in forums and tutorials and you guys are literally my last hope! Here it is .... I have a drop-down menu on a website I am working on which is made up of HTML, CSS and a little bit of Javascript. At the moment it is set so that when the user hovers over the menu it operates the drop-down. This obviously does not work for iPads etc as there is no mouse to hover. I want to keep my menu but alter the Javascript so the menu drops when clicked instead. Here is my code: Javascript Code: <script type="text/javascript"><!--//--><![CDATA[//><!--
startList = function() {
if (document.all&&document.getElementById) {
navRoot = document.getElementById("nav");
for (i=0; i<navRoot.childNodes.length; i++) {
node = navRoot.childNodes[i];
if (node.nodeName=="LI") {
node.onmouseover=function() {
this.className+=" over";
}
node.onmouseout=function() {
this.className=this.className.replace(" over", "");
}
}
}
}
}
window.onload=startList;

I realise that this must be quite an easy thing for you guys but - as I said - I am at the beginning of my learning and it is confusing the hell out of me! All of the things I have tried have not worked! Any help would be truly appreciated! Thanks in advance! Hello All, I'm trying to find a script that would be able to do the following: The are two drop down boxes, the first one populating the second (state/county --> town) The first box is single choice, the second is multiple choice. I'm looking for a script that would be able to deal with generating the code for all possible values that could be chosen in the second drop down box. The drop down boxes are part of a form which allow people to search for educational courses within areas of a state/county. I've had a good root around the internet but am rapidly getting confused ... many thanks in advance. Si. Hello! My first (but surely not last) post on this forum. I made a drop box menu and I want to activate specific javascript functions when they are selected. I think this should be fairly easy to solve. I am very new at HTML and Javascript btw. This is what I tried: if (document.getElementById("selectense").value="present"){ document.getElementById("present").style.visibility="visible"; } <span class="tensebox"> <select id="selectense"> <option onclick="showPresent()">Present</option> <option onclick="showPC()">Present</option> </select></span> (and I have some text with the ID "present) I know how to edit the CSS, and minute parts of the JavaScript code (for example; speed of the drop). The problem is, I had a massive amount of help making the Javascript side of the menu, and do not know how to edit it... I want the rules to still apply, where only one can be expanded at a time (one of the first drops, and then only one of the sub-drops). I noticed in the code, I can edit it so there can be more than one drop, but that would mean, the whole menu could be expanded Also, I want my sub-drops. to have different span colour than the main drop. but trhe links and such, (everything else about it) can be the same.... My live demo is here! Thank you for any help and/or advice in advance, Best Regards, Tim Hello, I have a drop down box, which display an images. It is also saved through a cookie on what option you leave it on. Is there a way you can make it so there are several drop downs on the same page that will also display images corresponding to the option chosen? Here's a live example: www.cirula.com/options here is my coding Code: <script language="javascript">
function linkrotate(which){
var mylinks=new Array()
//add in more links if you want (ie:mylinks[3]=...)
mylinks[0]="http://www.google.com"
mylinks[1]="http://www.ebay.com"
mylinks[2]="http://www.yahoo.com"
window.location=mylinks[which]
}

Hi guys, i'm trying to develop a code for my sister, i would like to use javascript to finish off the following task: 1. I want to be able to select marks from 0 to 30, from 5 drop down boxes. 2. and as marks are selected, it should upgrade the total. 3. and then show me the total marks when finished. i've got up to creating the drop down boxes, now it's just adding the values once selected. Thanks! anyhelp would be welcome Hi, I'm having trouble with trying to access a selected value of a drop down menu in a table. I have menus in columns 3 and 4, named cred and grade respectively, from rows 2 onwards, and I'm using a function to access them. How do I access the value's for manipulating other variables? Here is what I have so far: Code: function f(tableID){
var len = document.getElementById(tableID).rows.length;
for(var i = 1; i<len; i++){
var c = document.getElementById(tableID).rows[i].cells[2].childNodes[0];
credits = c.options[c.selectedIndex].text;
}
}
Your help would be really appreciated Hi all, I'm very new to Javascript and wonder if someone can help me. I'm creating an online enrolment form for my company, who are a training company. Users enrolling on the course must make three choices - The level of course, the size of course and whether they wish to attend a workshop or study by distance learning. The combination of these three factors will determine the price. I'd like to have the price automatically calculated using javascript and displayed on the form before they submit. Can anyone give me an idea of how to do this? There are three drop down boxes for users to select their course. They a - Level of Qualification: Level 3 Level 4 Level 5 Level 6 Scale of Qualification: Award Certificate Diploma Preferred Delivery Method Workshop Distance Learning Each possible combination of these will affect the price. So for instance, if the user were to select 'Level 4', 'Certificate' and 'Workshop' the price would be calculated based on these three options. How can I calculate the ultimate price and then display it on the page (I was thinking of using innerHTML in a 'span' element to display the final value, but if anyone has any better ideas I'd be glad to hear them) The HTML code for the drop down boxes is below: Code: <form action="enrolment.php" method="post"> <select name="level" class="input" id="level"> <option value="chooselevel"></option> <option value="Level 3">Level 3</option> <option value="Level 4">Level 4</option> <option value="Level 5">Level 5</option> <option value="Level 6">Level 6</option> </select> <select name="size" class="input" id="size"> <option value="choosesize"></option> <option value="Award">Award</option> <option value="Certificate">Certificate</option> <option value="Diploma">Diploma</option> </select> <select name="delivery" class="input" id="deliv"> <option value="deliverymethod"></option> <option value="Workshop">Workshop</option> <option value="Distance Learning">Distance Learning</option> </select> </form> Thanks all, hope someone here can help! Regards Chris *EDIT: I should mention that the form is also inside a table - Not sure if that will make a difference. ? how would i make it for a menu so you could press it and it would go down to click on a link.
I am stuck on this question. 1. To set the value contained in a field such as an input box, you must use the ____________________ property. This is based on Javascript. What type of properties are used for fields in an input box? Thanks I am trying to get these prompt boxes to display for age and resting heart rate. I cannot get this to work...This is what I have...any suggestions? <html> <head> <h1>Calculate Your Target Heart Rate</h1> <p>You can calculate your heart rate so that you can get the maximun results from your cardiovascular workout. Just follow these simple steps:</p> <script type="text/javascript"> function show_prompt() { var number = prompt ("Please enter your Resting heart rate:","Enter Rest Heart Rate Here!"); if (number! null && number! = "") var age = prompt ("Please enter your Age", "Enter Your Age Here!"); { document.write ("Your Resting Heart Rate is" + number); document.write ("Your Age is" + Age); } } </script> </head> <body> <input type ="button" onclick = "show_prompt ()" value = "Start Calculating Here!"/> </body> </html> Hi, I have a drop down menu, which you select an item and the text in a text box below displays according to what has been chosen from the drop down list. I have too much text in some case to appear in the text box, so i wanted to find some code so i can select different numbers for pages so i can display the information on different pages. Is this possible. Thanks |
