Topic awaiting preservation: Dynamic forms... (Page 1 of 1)

Righto,

What I'm trying to do is have a select list box with dynamically changing contents. Basically, I want it to have a list of users. Then I want to be able to call a few functions to add and delete users. Is there any way to do this at all? I've tried several ways..nothing seems to work. All I did was the select code..lol.

Thanks...

document.form.formname.Select.option[N] = null; will delete an option from the select list
document.form.formname.Select.option[num of options] = 'whatever' will add a new option to the list.

example code, from a project I've done

function PopulateRoom(id)

{

	var PopArray = new Array();

	if(id == 1) PopArray = Build1;

	if(id == 2) PopArray = Build2;

	

	optNum = document.forms.me.RoomType.length;

	// delete the options

	for(x=0;x<optNum;x++) 

	document.all.RoomType.options[0] = null;

	

	for(x=0;x<PopArray.length;x++)

	{

		var Room = PopArray[x].toString().split(":");

		document.all.RoomType.options[x] = new Option(Room[1],Room[0]);

	}

	

}

yeah, I know document.all is prob not the best way of doing it, but i know for certian the client is using IE and I'm lazy

Here: http://www.faqts.com/knowledge_base/index.phtml/fid/178 you can find loads of examples/questions on javascript and forms.

Some time back I took two pieces of code from here and merged them to create this little thing that allows you to add/delete/sort a selectbox from another selectbox and/or from creating all new values to choose from.

Perhaps it can be of help.
