Re: change selected item in drop down list

[Anja Friedrichsen]

Thanks for your answer Mark,
I am new with JavaScripts and I tried your example, but it does not 
really work...

I tried to do
   alert(options);
after
   var options = form.elements['select'].options[i];
but nothing happend. What exactly is that line doing?
Thanks, Anja

Yes you can select an option in a selection, but you would need to know the
index of the option.
form.elements['select'].options[i].selected = true;
When generating the select using the html:options argument your presentation
layer wont have much knowledge of the data passed so you will have to
recurse the options until you find one that matches your selection on the
map.
function somethingHappened(mapSelection) {
	var options = form.elements['select'].options[i];
	for(var i = 0; i < options.length; i++) {
		var option = options[i];
		if(option.value == mapSelection) {
			option.selected = true;
			break;
		}
	}	
}

Subject: change selected item in drop down list

Hi!
My application is based on stuts and contains among other thing a 
dropdown list and a graph. What I want to do, is to change the selected 
item in the drop down list, when clicking on the corresponding node in 
the graph.
Is it possible to change the selected item in a dropdown list?

My drop down list looks like that:
                     <html:select property="cvIdentification">
                         <html:options collection="cvIdentifications" 
property="shortlabel" labelProperty="shortlabel" />
                     </html:select>

Thanks in advanced!
Anja
