get text form listbox

[itazev]

Hey everyone!

 

I tried to google it but I could not find how to get a text of a listbox/combobox element.

Besides I tried getDataProperty("text") but does not worked.

 

I appreciate your help!

hmm, lets try to figure this out.

 

if a select looks like this:

 

<select id="test_select"><option>one</option><option>two</option></select>

 

var sel = document.getElementById('test_select');
var sel_children = sel.childNodes;
var opt = '';
for(var i = 0; i < sel_children.length; i++){
if(sel_children[i].hasChildNodes()){
opt += sel_children[i].firstChild.nodeValue +"\n";
}
}

 

alert(opt);

 

that should work, havent tested it. adapted from http://developer.mozilla.org/en/docs/DOM:element.childNodes

definitely had a massive brain fart

 

<select id="test_select"><option>one</option><option>two</option></select>

var opts = document.getElementById('test_select').getElementsByTagName('option');
var c = opts.length;
for(x = 0; x < c; x++){
alert(opts[x].value);
}
