when using javascript how would i create an if statement for a selected option

I am new to javascript however I am trying to create a if else statement with the following options. 

<select name="remote_server" class="required">
<option></option>
<option value="1" <?php if($remote=="1") echo 'selected="selected"'; ?>>Yes</option>
<option value="0" <?php if($remote=="0") echo 'selected="selected"'; ?>>No</option>
</select>

I am looking to do something like 

if remote_server = 1 then 
    document.getElementByName("hostname").disabled = true;
else 
    nothing

EDIT 1:

I am now trying the following with no success

var e = document.getElementsByName("remote_server");
var strUser = e.options[e.selectedIndex].value;

if ( strUser == 0 ) {
    document.getElementsByName("ftp_hostname").disabled = true;
}

getElementsByName returns an array of elements, so if you want the first element named "remote_server", you should use document.getElementsByName("remote_server")[0].

Similarly, you'll want to use document.getElementsByName("ftp_hostname")[0].disabled.
