I need to add items into a dropdown list, and the items would be sorted alphabetically and it does not allow duplicate items to be added.
Javascript
function addAnotherOption()
{
var newItem = document.getElementById("Text44");
if (!newItem.value == "")
[Code]...
I would like to prevent the addition of duplicate items in the following situation.Firstly, I have a listbox with a few options such as
<select id="listbox" name="listbox" multiple="multiple" style="width: 580px;">
<option>Java</option>
<option>PHP</option>
[code]....
I am having a table with rows created using a button click event. While adding rows to the table, I create drop dowlist using
Code:
objVehicles = document.createElement("<SELECT class='dropdownbox' id=Vehicles"+objAlertRowId+" name=Vehicles"+objAlertRowId+" STYLE='width:148px'; onchange='setDataChanged();toggleEditButton(" + objAlertRowId+ ",this.value);' >");
objNewRow.cells.item(3).appendChild(objVehicles);
And the output will be like the attached screen shot.
The control name as Vehicles0,Vehicles1 and so on Now I want to restrict that the the user select no duplicates from the List.
What logic I can implement ?
Okay guys, this might be very simple, but i just cant find the answer.
What i want to do is prevent users from submiting entries that already exist in the database using php. code...
All want is to be sure that if the there is an existing row in name with an entry of 'asdf' (example) then it will echo something like name already exists, but if it doesnt i want it to echo okay. What happens is that it ALWAYS echos okay, in other words it always says there is no row named 'name' with the value of 'asdf'

I am working with ASP.NET. I have a TextBox and DropDownList (for customer
info input) that I need to tie up, i.e., when the DropDownList item changes
(the customer name), the TextBox should reflect the selected value (the
customer number). And when a user types something in the TextBox and exits
the control, the DropDownList item should be changed to that value, showing
the corresponding customer name.
I have this web browser which opens up a website(which is actually a .java page that sets and gets a page) that has a drop down list showing values that the user can select.

<option value="1">Item0</option>

I'm attempting to write a piece of code that acts as a client side
validator for all drop down lists on a webform, giving an error if the
SelectedIndex = 0.
Here is what i have:
function clientValidateDDL(source, args)
{
var dropdown = document.getElementById(source*.controltovalidate) ;
if (dropdown.selectedindex == 0)
{
args.IsValid = false;
}
else
{
args.IsValid = true;
}
}
However, it does not give an error for any selected index, including
index 0, so i'm presuming the var dropdown = ... line is not correctly
selecting the dropdownlist that launched the function.
ClientValidationFunction="clie*ntValidateDDL" is inserted in the
custom validator tags. and ControlToValidate is also present and correct.
