Populating A Dropdown From An Array?

Jun 24, 2010

I am using Moodle and need to make an amendment in one of the modules using a little bit of Javascript.

I have an array called [[Loacation]] I want to create a dropdown in an HTML from which will populate from this array. I could probably just about do it in php using the foreach command, but I need to be able to do it clientside using Javascript.

"Undefined" Array Error When Populating Dropdown Box?

May 10, 2009

I use ASP to write the arrays at the start of my page:

<script language="Javascript">
var ArrManu1 = new Array();
var ArrManu2 = new Array();
var ArrManu3 = new Array();

[Code]....

...to populate the second dropdown box. However, when the user selects the first option in the first dropdown box (therefore making the variable "Co" equal to 1), ((ManuArr[Co-1])[i-1]) is "undefined" - why doesn't it add "Bell" to the dropdown?

Populating Inputs From Select Dropdown?

Jul 20, 2010

I am trying to populate inputs on a form from a select drop down list (with date being pulled from a mysql database). This is to allow for any changes that need to be possibly made.

Is this even possible? I've tried doing some internet research, and the books I picked up from the library don't seem to go into this at all, so I'm not even sure that what I want to do is possible. The only thing I can really seem to think is that i need to use onChange. But outside of that, i'm lost.

Automatically Populating Another Field From A Dropdown

Oct 4, 2010

I have built myself an invoicing system and I am in the midst of upgrading it. Currently I have a dropdown box with all the items we sell in it and next to that a unit price text field. Currently you select the item and them manually type in the price. The issue is you have to know the price. What I want to do is once you choose an item it automatically adds the unit price. I am sure this is easy and have a funny feeling I have done this years ago. If anyone can point me in the right direction that would be great. An example or download code would be even better.

JQuery :: Populating Checkboxes Dyn - From Select Dropdown

Mar 23, 2011

This is for a test, am not sure what they mean by "do not hard-code the resulting quarter years in the javascript":

instructions: When a user selects a date from the investment cycle drop-down box, the subsequent investment values must display the next three fiscal quarters.

E.g:

Do not hard-code the resulting quarter years in the javascript. (empahsis mine...;-)

The subsequent quarters should be presented with checkboxes which are all unchecked.

Checkboxes in markup:

The values to populate the checkboxes (value and label) have to be hardcoded somewhere, no? what am I missing?

AJAX :: PHP Multiple Dropdown - Populating From The Menu

May 25, 2009

The second menu is populating correctly from the first menu. The third menu doesn't work because it is not pulling the cat1 & cat2 values. I suspect it is the "checkNew" function, which I tried (with limited Javascript knowledge) to copy and alter from the "checkSelected" function.

the following code is what I use to populate the second drop down

$.ajax
({
type: "POST",
data: "company=" + $(this).val(),

Populating SELECT Options From An Array?

Mar 26, 2009

I originally posted this question in the PHP forum and received advice to try here, they said it might be possible using JS and AJAX.I have limited experience with JS and none at all with AJAX.I have an HTML form in which I have a Select field, currently with about 100 options. The form creates an HTML email using formmail.Dependent on the option taken I get other details, eg address, email, telephone, etc.This is begging to be done via a database and PHP.I do not know if this is possible, but could I open the database, MYSQL, and take all the records into an array, open the HTML form and use one of the fields of the array to create the options list, when an option is selected use the other fields in the array to fill in the address, email, etc fields on the form and then use those values as variables to pass to formmail, which is a PHP program.

I thought that if this was possible I would use PHP to populate the array and then get it to call the HTML form where I could hopefully use the array to help complete some of the fields using SELECT.I would like to know if my thoughts are going in the right direction or if I need to go down another track.

Populating 'Select' Objects With Data From An Array

Apr 7, 2004

I am populating a ‘Select’ object with data from an Array, and I succeed in load the page with the required data on the ‘Select’ dropdown list. But when I see the source code generated (view-source code) from the browser there is no option on the ‘Select’, you can see this form the browser source code:

...
<body>
<form name="localization">
States: <select name="countries"></select><br><br>
Cities: <select name="cities"></select>
</form>
...

And I want that appears the options generated in order to be able to talk with server, because server is waiting for some value (1, 2, 3 or 4). Now when I submit the form the server don’t recognize the option (value) received. So maybe the source code generated should be: Code:

JS Array For A DropDown

Dec 29, 2007

I'm working with Adobe LiveCycle, and I'm not certain how different that is from working with web stuff. Any ideas why this doens't work?

var RoomNum=new Array(5)
RoomNum[0]="1";
RoomNum[1]="2";
RoomNum[2]="3";
RoomNum[3]="4";
RoomNum[4]="5";
RoomNum[5]="6";

if (DropDownList1.rawValue == 0) {
DropDownList4.addItem (RoomNum);}

Instead of giving me the 6 numbers, I just get the word "empty"

Dropdown Box Populated From Php Array

Mar 31, 2010

I've created a page that uses 2 seperate functions for passing variables.The first runs when the page loads and requests categories from a database to fill a dropdown box.The second function sends a date value and the contents of the select from the dropdown box to search a database then outputs the results to the page.They both use getelementbyid to display their results. the category search uses <div id="txtindex"> and the date/dropdown search uses <div id="txtupdate">My problem is the results from the date/dropdown which should display in the 'txtupdate' div are displaying where the dropdown box used to be, so in the 'txtindex' div.

Array In Dropdown Print Value Into Read Only Textbox

Apr 27, 2011

Code:
<label for = "Service">Service Required</label>
<select id= "Service">
<script type="text/javascript">
for (var i=0; i<service.length; i++)
{document.writeln("<option>" + service[i] + "</option>");}
</script>
</select>

Using this creates the dropdown box though I want to take
Code:
var service = new Array();
//log book services available
service[0] = "12 month log book service";
service[1] = "18 month log book service";
service[2] = "24 month log book service";
service[3] = "30 month log book service";
service[4] = "36 month log book service";
service[5] = "Other minor service";
service[6] = "Other major service";

var price = new Array();
//prices log book services available
price[0] = "255";
price[1] = "285";
price[2] = "530";
price[3] = "255";
price[4] = "285";
price[5] = "285";
price[6] = "540";

This is to show the expected data at this point in time though I may add or remove elements so I want the code to be flexible a= ie iterative so I want to have the dropdown element checked and compare the position of service to get the associated price though they are in two seperate arrays and cannot be changed. Basically I would like to use a if selected value the price at that position is entered into the textbox which is readonly. How would I go about this and I cannot use tools such as jquery to do this. Is there a way to set the select value to the array position on price or something as I have never had to compare two arrays or print a selected value to a textbox.

Pass The Value Of Dropdown To A Function And Enable Another Dropdown

Mar 7, 2010

I have 4 strands of hair left... I have been fighting with this one for almost a week now. I'm trying to pass the value of this dropdown to a function and enable another dropdown(and in the future create the populated dropdown based on this choice). If the original 'Select...' option is chosen it will then hide that second dropdown. In the following code the function actually resides in a js file which has been imported and is working properly. I have tried this as text and as value and both seem to be passing a null value regardless of the option selected.
