JavaScript - Customizing Dynamic Select Boxes

Customizing Dynamic Select Boxes	View Content

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?

Ie9 Breaks Dynamic Select Boxes

View Content

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.

Multiple Sets Of Dynamic List Boxes

I'm trying to use this code to create 6 sets of (each set 2 Dynamic List boxes). However I have the problem that Category 1-6 selection does not select the correct (adjacent) subcateory list box and instead populates the last selection in subcategory list box 1. How can I set the Java/HTML code so that for example Category #3, populates the selection/case into SubCategory#3 list box?

Form Code (only with 2 Category, SubCategory) this when working will be expanded to 6.

Code:

<table border="0" width="560">

<tr>
<td align="center"><strong>Item#</strong></td>
<td align="center">Paint Type</td>
<td align="center">Colour</td>
<td align="center">Litres</td>

      <option value="">Select Range</option>
      <option value="New Paint">New Paint</option>
      <option value="Recycled Paint">Recycled Paint</option>
    </select></td><td name="cell1">

 <input class="formbox" size="5" name="02_litres" /></td>

			document.SampleForm.subcategory1.options[4]=new Option("Camera","Camera");
			document.SampleForm.subcategory1.options[5]=new Option("Cell Phones","Cell Phones");
	
	break;
	
		case "Recycled Paint" :

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?

2 Select Boxes In 1 Form With Onchange Display

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">
// <![CDATA[
function display(obj,id1,id2,id3,id4) {
txt = obj.options[obj.selectedIndex].value;
document.getElementById(id1).style.display = 'none';
document.getElementById(id2).style.display = 'none';
document.getElementById(id3).style.display = 'none';
document.getElementById(id4).style.display = 'none';
if ( txt.match(id1) ) {
document.getElementById(id1).style.display = 'block';
}
if ( txt.match(id2) ) {
document.getElementById(id2).style.display = 'block';
}
if ( txt.match(id3) ) {
document.getElementById(id3).style.display = 'block';
}
if ( txt.match(id4) ) {
document.getElementById(id4).style.display = 'block';
}
}
// ]]>
</script>
</head><body>

<form action="#">
<select name="Stype" onchange="display(this,'oneshot','outtake','multi','chapter');">
<option>Please select:</option>
<option value="oneshot">Oneshot</option>
<option value="outtake">Outtake</option>
<option value="multi">Original Multi-Chapter</option>
<option value="drabbles">Drabbles</option>
<option value="outline">Outline Preview</option>

</select><BR><BR>

<div id="multi" style="display: none;">Some other fields here</div>
<div id="chapter" style="display: none;">Some more fields here</div>
</form>

Javascript Select Boxes, Onchange Event Help

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.

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.

Extracting Values From Select Boxes And Summing The Result

Similar Tutorials

View Content

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

Help With Dynamic Select Box Error

Similar Tutorials

View Content

Hello all! I am hoping for some coding help as I have been trying to figure out my problem for a couple of days without resolve. I am new to Javascript so this is just test code that eventually will go into a larger project. Here goes:

I have a form that initially creates two select boxes. The 2nd select box option values are determined onchange of the first boxes value using mysql to pull the data from a database. That all works fine.

I also have an add button that adds a second set of select boxes dynamically and assigns names and values, etc. This also works fine. My goal is to have the 2nd set of select boxes act the same as the first so that when an option is chosen in the first box the 2nd dynamically populates. This does not work. The first box is created fine but when it tries to create the values in the 2nd from an onchange event I have a problem.

This is the code that returns a valid object with the first set of select boxes but is null with the 2nd set.
Code:

var selbox = document.getElementById(exep);

The entire piece of spaghetti code is below. Any help is appreciated. Please be nice as I am still trying to figure out this Javascript stuff. Thanks for any help...

"multiple Dynamic Combo Boxes" Configuration

Hello,

I'm using "Cut & Paste Multiple Dynamic Combo Boxes" script. I want to configure it, so at first only 1st combo box is visible and the rest are hidden and only populate based on the selections. Also, when the last parameter (from the 5th combo box) was selected, I need to show the table with the search results based on the all selected parameters.

Here is what I have so far:
Code:

This script is used in my html page and I don't have a database to choose from. So, I wonder if it's possible to make all these modifications with only html and JavaScript. Any help will be appreciated.

Thanks in advance.

Hello all.

First name.
Last name
Area code.

My assignment was to do this, and put the information is as follows.

If both, first name & last name are entered, store in object as

last name,first name.

If only one is entered. display without the comma.

Also store telephone number in (XXX) XXX-XXXX format.

I was told to use methods to do all of these things.

Please take note I am in a VERY basic javascript class.

Thanks in advance.

Hi All,
i know how to create a dynamic form or DIv ..but what i do not know is how to create a dynamic form/ or div into a previous dynamic one..

i need basically to see 5 dynamic forms / DIV in cascade where each one trigger the one coming after..

For what i need that :

i have my user inserting information on the level 1. let say Copagny info
2- then he will be asked if he wants to add a sub level information ( subform) for that compagny or even many subforms at the same level ..
and so on...

3- those sub level ( subforms ) can also call their respective subforms..

Any idea how to design this ?

thanks

Dynamic Calculation For Dynamic Form

I have made a script where you can add extra fields, and next to the row is a span that automatically displays the outcome from a calculation of three fields in that row. i.e. Q x (B - A) = total.

Here is the bit that does the calculation:
Code:

function advCalc(selected) {

	var result = Number(document.formmain.elements["quantity"+selected].value) * (Number(document.formmain.elements["provideamount"+selected].value) - Number(document.formmain.elements["supplyamount"+selected].value)) ;

	result = result.toFixed(2) ;
	result = addCommas(result) ;
	
	document.getElementById("total"+selected).innerHTML = result ;

}

The bit that adds a new row of fields is:
Code:

function addPart(divName){
          var newdiv = document.createElement('div') ;
		  newdiv.setAttribute('id', 'partrow' + counter) ;
		  newdiv.setAttribute('style', 'clear:both;') ;
          newdiv.innerHTML = "<div style='float:left;width:40px;text-align:center;margin:5px 5px 0px 0px;'>\r<input onkeyup=\"advCalc('" + counter + "')\" id=' quantity " + counter + "' type='text' value='1' size='1'/>\r</div>\r<div style='float:left;width:100px;text-align:left;margin:5px 0px 0px 0px;'>\r<input id='manufacturer" + counter + "'type='text' value='' size='9'/>\r</div>\r<div style='float:left;width:95px;text-align:left;margin:5px 5px 0px 0px;'>\r<input id='partnumber" + counter + "'type='text' value='' size='9'/>\r</div>\r<div style='float:left;width:80px;text-align:left;margin:5px 5px 0px 0px;'>\r<input id='supplier" + counter + "'type='text' value='' size='4'/>\r</div>\r<div style='float:left;width:100px;text-align:left;margin:5px 5px 0px 0px;'>\r<input id='type" + counter + "'type='text' value='' size='6'/>\r</div>\r<div style='float:left;width:85px;text-align:left;margin:5px 5px 0px 0px;'>\r<input id='deliverytime" + counter + "'type='text' value='' size='13'/>\r</div>\r<div style='float:left;width:40px;text-align:left;margin:5px 0px 0px 45px;'>\r<select id='supplyCurrency" + counter + "'>\r<option value='pound' selected='selected'>&pound;</option><option value='dol'>$</option><option value='euro'>&euro;</option></select>\r</div>\r<div style='float:left;width:15px;text-align:left;margin:5px 5px 0px 0px;'>\r<input onkeyup=\"advCalc(\'" + counter + "\')\" id=' supplyamount " + counter + "'type='text' value='' size='3'/>\r</div>\r<div style='float:left;width:40px;text-align:left;margin:5px 0px 0px 45px;'>\r<select name='provideCurrency" + counter + "'><option value='pound' selected='selected'>&pound;</option><option value='dol'>$</option><option value='euro'>&euro;</option></select>\r</div>\r<div style='float:left;width:15px;text-align:left;margin:5px 5px 0px 0px;'>\r<input onkeyup=\"advCalc(\'" + counter + "\') id=' provideamount " + counter + "' type='text' value='' size='3'/>\r</div>\r<div style='float:left;width:20px;text-align:left;margin:5px 0px 0px 45px;'>\r<strong>&pound;</strong>\r</div>\r<div style='float:left;width:40px;text-align:left;margin:5px 5px 0px 0px;'><span id=' total " + counter + "'></span></div> \r" ;
          document.getElementById(divName).appendChild(newdiv) ;
          counter++ ;
}

The problem I am having is that it works fine for the first row which is hardcoded as e.g. id="provideamount0" etc.

It isn't working for any other fields added but I can't see what is wrong

Change Options Of Select Based On Selection In Other Select

I've been having problems getting my select option to change the options of another select option. I'm not much of a javacsript coder, so I'm at a lost.

When I select the first option nothing appears in the second option.

here's the javascript code:

Code:

function createOption(OptionText, OptionValue){
var temp = document.captcha_form("option");
temp.innerHTML = OptionText;
temp.value = OptionValue;
return temp;
}

function valChange(){
    var firstList = document.getElementById("emailaddress");
    var secondList = document.getElementById("subject");
    while(secondList.hasChildNodes())
        secondList.removeChild(secondList.childNodes[0]);
    switch(firstList.value){
        case "1":{
             secondList.appendChild(createOption("Report Site Browsing Issue", Report Site Browsing Issues));
             secondList.appendChild(createOption("Report Page Errors", Report Page Errors));
             secondList.appendChild(createOption("Other", Other));
             break;
        }
        case "2":{
             secondList.appendChild(createOption("Report Unauthorized Game", Report Unauthorized Game));
             secondList.appendChild(createOption("Report Spam", Report Spam));
             secondList.appendChild(createOption("Report Harassment", Report Harassment));
			 secondList.appendChild(createOption("Report Illegal Activities", Report Illegal Activities));
			 secondList.appendChild(createOption("Request Account Removal", Request Account Removal));
             break;
        }
// ....
        default:{
             secondList.appendChild(createOption("Please select from the first list", ""));
             break;
        }
    }
}
 
window.onload = valChange;

this is the form code

Code:

<div class="mailto_form">
<form method="POST" id="captcha_form" name="captcha_form" action="../includes/mailform.php">
<div style="padding-bottom: 1em;">Choose Recipient: <select name="emailaddress" id="emailaddress" onchange="valChange();">
	<option value=""></option>
	<option value="1">Webmaster</option>
		<option value="2">Admin</option>
		</select>
  </div>
	

<div style="padding-bottom: 1em;">Subject: <br /><select name="subject" id="subject">

Hey chaps, hope someone can help with this:
I have a PHP form, with a couple of dynamic Select menus, which are populated from two SQL tables:
// tbl_main_colour:
Code:

ID, NAME
1, Red
2, Blue
3, Green

// tbl_shade_colour:
Code:

ID, NAME, FK_MAIN_COLOUR_ID
1, Light Red, 1
2, Dark Red, 1
3, Light Blue, 2
4, Dark Blue, 2
5, Light Green, 3
6, Dark Green, 3

What I'm after is something to filter the second select option, after the first select option has been chosen
// Select 1:
Code:

Red

// Select 2:
Code:

Light Red
Dark Red

I'm pretty sure this is possible, but not sure how to go about it, any help would be most appreciated.
