There couldn't be a variable with name `var` :) – VisioN Mar 13 '13 at 09:10

Can you be a little more specific? Are you trying to use String.substring()? – HeremansY Mar 13 '13 at 09:11

HTML
<select id="sel">
<option value="Volvo">Volvo</option>
<option value="BMW">BMW</option>
</select>
JS
var myvar = 'b';
var elem = document.querySelector('#sel option[value^='+myvar.toUpperCase()+']');
if (typeof elem != 'undefined') {
elem.selected = true;
}
Here you can test -> http://jsbin.com/ehayav/1

May be this will help you :
//array of varables
var names = ['apple','banana','valvo','blahblahblah']
//this is your variable
var variable = 'v'
//code to display names starting with the character in your variable
for(i=0;i<names.length;i++)
if(names[i][0] == variable)
alert(names[i])
This answer is for my interpretation of your question. EnjoY!

Please make your question more clear. What you want to exactly do ? Do you want to dynamically create a select box like this : '' – codeVerine Mar 13 '13 at 10:20
