JavaScript - Need Help. Javascript Select Boxes Using Arrays
I'm trying to do this using numerical arrays for an assignment:
Create a webpage with three select boxes. If basketball is selected in the first select box, the second select box should display the names Celtics, Lakers, and Bulls. If Celtics is selected from the second select box, the third select box should display the names Larry Bird, Bill Russell, and Kevin McHale. I think i have a good start but i can't seem to get the fields to automatically populate with the players. This has to be done solely with JavaScript. Any help would be greatly appreciated? <html> <head> <script type="text/javascript"> <!-- var teams = new Array() teams[1] = new Array() teams[1][0] = "Celtics" teams[1][1] = "Lakers" teams[1][2] = "Bulls" teams[2] = new Array() teams[2][0] = "Yankees" teams[2][1] = "Cardinals" teams[2][2] = "Reds" var basketball = new Array() basketball[0] = new Array() basketball[0][0] = "Larry Bird" basketball[0][1] = "Bill Russell" basketball[0][2] = "Kevin McHale" basketball[1] = new Array() basketball[1][0] = "Wilt Chamberlain" basketball[1][1] = "Jerry West" basketball[1][2] = "Magic Johnson" basketball[2] = new Array() basketball[2][0] = "Micheal Jordan" basketball[2][1] = "Scottie Pippen" basketball[2][2] = "Dennis Rodman" var baseball = new Array() baseball[0] = new Array() baseball[0][0] = "Babe Ruth" baseball[0][1] = "Joe DiMaggio" baseball[0][2] = "Mickey Mantle" baseball[1] = new Array() baseball[1][0] = "Mark McGuire" baseball[1][1] = "Ozzie Smith" baseball[1][2] = "Willie McGee" baseball[2] = new Array() baseball[2][0] = "Pete Rose" baseball[2][1] = "Johnny Bench" baseball[2][2] = "Joe Morgan" function fillTeams() { var whichIndex = document.getElementById("theSport").selectedIndex var numberOfTeams = teams[whichIndex].length for(i=0;i < numberOfTeams; i++){ document.getElementById("theTeams").options[i].text = teams[whichIndex][i] } } function fillPlayers() { var whichIndex = document.getElementById("theTeams").selectedIndex if(document.getElementById("theTeams").selectedIndex=="basketball") var numberOfPlayers = teams[teams[whichIndex]].length for(i=0;i < numberOfPlayers; i++) { document.getElementById("thePlayers").options[i].text = basketball[teams[whichIndex]][i] } else if(document.getElementById("theTeams").selectedIndex =="baseball") for(i=0;i < numberOfPlayers; i++) { document.getElementById("thePlayers").options[i].text = basketball[teams[whichIndex]][i] } } //--> </script> </head> <body> <form> <select id="theSport" onChange="fillTeams()"> <option>Choose a Sport</option> <option>Basketball</option> <option> Baseball </option> </select> <select id="theTeams" onChange="fillPlayers()"> <option>................</option> <option></option> <option></option> </select> <select id="thePlayers" size="3"> <option> ...............</option> <option></option> <option></option> </select> </form> </body> </html> Similar TutorialsCalculating quiz answers?

Hello, I am working on a CGI/Ajax application to interface with a database. I have the back-end Perl/CGI application working, so now it it is time to design the web interface and respective forms. So here goes, I am attempting to create dynamic list boxes, but I am unable to pass a value to the 'onChange' event. Here is my code (this is a proof of concept and highly stripped down): Code: <html>
<head>
</head>
<body>
<SCRIPT LANGUAGE="JavaScript" TYPE="text/javascript">
var array = [ 'name', 'age', 'year'];
function init(sel_val){
for (var i = 0; i < array.length; i++){
document.write(i + " " + array[i] + "<br />");
}
for (var i = 0; i< array.length; i++){
document.product.id_type.options[i] = new Option(i + array[i], i);
}
}
function OnChange(sel_val) {
// for(i = document.product.id_style.length - 1; i > 0; i--)
// document.product.id_style.options[i] = null;
// document.product.id_style.options[0] = new Option("something else", 15);
alert("pressed" + " " + sel_val + "<br />");
}
</script>
<form name="product">
<select name="id_type" size="5" style="width: 150px;" onChange="OnChange()"></select>
<select name="id_style" size="5" style="width: 150px;" ></select>
</form>
<script>
init();
</script>
</body>
</html>
I'm well versed in Perl and Java but I am a JavaScript newbie, so go easy. I understand that sel_val is not being set, but I'm not sure how it should (or could) be set. I would like to use a hash instead of integer values for `i` document.product.id_type.options[i] = new Option(i + array[i], i); becomes document.product.id_type.options[i] = new Option(hash[key], key); Any thoughts, comments, criticisms, jokes are welcome. Thanks in advance for the assist. hi ! i would like to write the code for multiple text box select as shown in the link below: http://www.downloadplex.com/Mobile/I...ne_284120.html please see the screen shot 3 Hi all, I'm trying to customize a script I found. It's about two select boxes, one for continent selection and one for country selection. When user selects a continent from the first select box, the second select box is filled with the list of the proper countries that belong to this continent. You can see that code of the script he http://www.howtocreate.co.uk/jslibs/htmlhigh/countryselect.html In my page, the continent select box is loaded with a continent-value already selected (the selection depends on a database value) and I want to have the second countries select box, also loaded with the proper countries. I cannot make this happen, unless I change the continent's selection and trigger the onchange event. Can I someway keep the onchange event and also add the ability to have a continent and it's list of countries already loaded? I have the below JS code to change up a select box based on what is selected in another select box. IE9 broke this somehow. It still works in other browsers as well as IE8 and IE7. When you select something in select box A, it properly populates select box B. However when you go back and change select box A again the script stops working completely. The error I'm getting from the IE9 developer tools debugger is: SCRIPT65535: Invalid calling object dynamicselect.js, line 31 character 18 I have bolded the relevant line below. Code: function dynamicSelect(id1, id2) {
// Browser and feature tests to see if there is enough W3C DOM support
var agt = navigator.userAgent.toLowerCase();
var is_ie = ((agt.indexOf("msie") != -1) && (agt.indexOf("opera") == -1));
var is_mac = (agt.indexOf("mac") != -1);
if (!(is_ie && is_mac) && document.getElementById && document.getElementsByTagName) {
// Obtain references to both select boxes
var sel1 = document.getElementById(id1);
var sel2 = document.getElementById(id2);
// Clone the dynamic select box
var clone = sel2.cloneNode(true);
// Obtain references to all cloned options
var clonedOptions = clone.getElementsByTagName("option");
// Onload init: call a generic function to display the related options in the dynamic select box
refreshDynamicSelectOptions(sel1, sel2, clonedOptions);
// Onchange of the main select box: call a generic function to display the related options in the dynamic select box
sel1.onchange = function() {
refreshDynamicSelectOptions(sel1, sel2, clonedOptions);
};
}
}
function refreshDynamicSelectOptions(sel1, sel2, clonedOptions) {
// Delete all options of the dynamic select box
while (sel2.options.length) {
sel2.remove(0);
}
// Create regular expression objects for "select" and the value of the selected option of the main select box as class names
var pattern1 = /( |^)(select)( |$)/;
var pattern2 = new RegExp("( |^)(" + sel1.options[sel1.selectedIndex].value + ")( |$)");
// Iterate through all cloned options
for (var i = 0; i < clonedOptions.length; i++) {
// If the classname of a cloned option either equals "select" or equals the value of the selected option of the main select box
if (clonedOptions[i].className.match(pattern1) || clonedOptions[i].className.match(pattern2)) {
// Clone the option from the hidden option pool and append it to the dynamic select box
sel2.appendChild(clonedOptions[i].cloneNode(true));
}
}
}
Thank you in advance for any help provided. I'm using onchange display to hide/show form elements depending on the value of a select box. It works perfectly well (I actually really adore it) for one select box, but I have another select box which I'd like to act similarly. Code: <head>
<script type="text/javascript">

Is there any way to fuse them and get a second select to work the same? Thanks in advance for the help! Hello, I'm working on a project that involves extracting values from a series of select boxes and then working out the result. The select boxes contain the following: Code: <select name="select_Col1_Row1"> <option value="blue">Blue</option> <option value="green">Green</option> <option value="red>Red</option> </select> <select name="select_Col1_Row2"> <option value="blue" selected="selected">Blue</option> <option value="green">Green</option> <option value="red>Red</option> </select> <input type="text" name="RedSum"> <input type="text" name="BlueSum"> <input type="text" name="GreenSum"> </select> As you can see by my code, I'm early days at this and guessing the steps on the way. I tried using getElementsByTagName on the select and then on the option but had no luck with that. The code below does a wonderful job of returning blue for both select statements... Code: <script type="text/javascript">
function getElements()
{
var table = document.getElementById("x");
var x = table.getElementsByTagName("option");
for (var i = 0; i < x.length; i++) {
var status = x[i].getAttribute("selected");
alert(status);
if (status == "selected") {
var statushcap = x[i].getAttribute("id");
var statusvalue =x[i].getAttribute("value");
if (statusvalue == "blue") {
alert(statusvalue);
}
}
}
alert(x.length);
}
</script>
If someone could suggest some way to map the select tag and then extract its option value to being the user selected value, I'd most appreciate it. I can probably do the rest of it. Can you extract additional information from the id of the option that is selected as I'd like to sum additional information from the user's choice. Best, John Hello to all and thank you for any help beforehand. I have an issue with the script below, Select the top dropdown and the second gets populated, this is a nice piece of script, the only problem is that when the information is posted and presented on the process page I click page back to the form to rectify some other field but the ajax resets so I have to select Country & City each time even if thease fields are correct. I know that back button as well as bookmark is a problem with ajax but i think there is a solution the only thing is I don't know how to apply it to this script.

Ok so I'm making this form which when a selection is made in one box it will run through the javascript(function getMgmtHours), and update the div(mgmthours). Then another box shows up allowing another selection to be made which runs through the javascript(function getDays) and updates another div(mgmtdate). My problem is that when I use the second box to run through javascript, it overwrites what shows up in the first div (mgmthours) when it should be updating a different div (mgmtdate). Any ideas what I can do to get it update the relevant div and not overwrite the other one? Here is part of the javascript I have in my page head: Code: function getMgmtHours(str)
{
if (str=="")
{
document.getElementById("mgmthours").innerHTML="";
return;
}
if (window.XMLHttpRequest)
{
// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("mgmthours").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","getmgmthours.php?dist="+str,true);
xmlhttp.send();
}
function getDays(str)
{
if (str=="")
{
document.getElementById("mgmtdate").innerHTML="";
return;
}
if (window.XMLHttpRequest)
{
// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("mgmtdate").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","getdates.php?sunday="+str,true);
xmlhttp.send();
}
Here is the HTML/PHP portion being used: PHP Code: echo "<p>"; echo "Submit hours:"; echo "<form>"; echo "<select name='district' onchange='getMgmtHours(this.value)'>"; echo "<option value=''>Select a district:</option> <option value='1'>1</option> <option value='3'>3</option> <option value='4'>4</option>"; echo "</select>"; echo "</form>"; echo "</p>" echo "<p>"; echo "<form action='./hours.php' method='post' onSubmit='return checkMgmtHours'>"; echo "Weekending Day: "; echo "<select name='weekending' onchange='getDays(this.value)'>"; echo "<option value=''>Choose a Date:</option>"; while ($week < 32) { $nextsunday = strtotime("next Sunday"); if ($week > 0) { $timestamp = strtotime("-" . $week . " week", $nextsunday); } else { $timestamp = $nextsunday;} $weekending = date('M. d, Y', $timestamp); echo "<option value='" . $weekending . "'>" . $weekending . "</option>"; $week = $week + 1; } echo "</select>"; echo "<div id='mgmtdate' />"; echo "<div id='mgmthours' />"; echo "</p>"; Edit: Also, after getMgmtHours() runs, I can still use both getDays and getMgmtHours, howeer once I used getDays, I am no longer able to use getMgmtHours w/o refreshing the page. 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 I have the following page www.crownvalleywinery.com/kiosk/default.html and I would like to add a button or checkbox to check/uncheck all. Note we are already using some javascript for custom checkboxes so it needs to integrate with that. Any help is appreciated. Here is the current javascript... Code: /*

The only thing you need to change in this file is the following
variables: checkboxHeight, radioHeight and selectWidth.
Replace the first two numbers with the height of the checkbox and
radio button. The actual height of both the checkbox and radio
images should be 4 times the height of these two variables. The
selectWidth value should be the width of your select list image.
You may need to adjust your images a bit if there is a slight
vertical movement during the different stages of the button
activation.

The moment i posted it i realised the mistake i was making . Learnig how to delete my post, until then thought i would sdimply delete the content.
Hi, I'm kinda newbie in javascript and would really like some help if you wouldn't mind? I'm working with dreamweaver and VBScript and have drop down lists being populated by dynamic recordsets, the tables that are being used are text fields and everything is working fine other than one niggly thing I want to do and just don't seem to be able to get the javascript code right The data I have has two columns; area and technical issue. As the area contains duplicates I have this as a separate drop down list with a distinct in the sql command and from an onclick event from the 'area' drop down list, I get the value of the selected item [var x = document.NewFacilityAdminDetailsTest.ara_component.selectedIndex; var ara_component = document.NewFacilityAdminDetailsTest.ara_component.options[x].value;] all's well so far.... The second drop down list contains all the 'technical issues' which is great, BUT because its a dynamic recordset its for ALL of the areas and I want to be able to take away the technical issue values in the technical issues drop down list that don't belong to the area that's been picked and I also dont' want the user selecting a technical issue that isn't linked of the area. I've tried some of the samples I've found by googling and even the adobe example but they all seem long winded and I never quite get the code right and the second drop down list just keep showing ALL 'technical issues show' for ALL of the 'areas'. Surely there's a bit of javascript to turn the second drop down list recordset into an array, loop through the array and remove the technical issues that don't match the selected value from the 'area' drop down list and put the array into the second drop down list instead of using the recordset? Any help would be soooooo useful. Best Regards Joan, Cheshire Any suggestions on how the javascript below should be changed so it will work with checkboxes that have brackets in the name? (I'm using foreach in php, and can't seem to get the php to work/work correctly without using them.) Thanks! Code: function chktotal(j) {
var total=0;
for (var i=0; i < document.form1.ckbx.length; i++){
if(document.form1.ckbx[i].checked){
total=total+1;
}
if(total>8){
alert("Please only select 8");
document.form1.ckbx[i].checked = false;
total = total -1;
return false;
}
}
document.form1.totalval.value = total;
}
<input onclick="chktotal(2)" value ="Sample Item 1" type="checkbox" name="ckbx[]">
