Dropdown using javascript onchange


I have a simple drop down and I want to have it so that if the user selects Have a Baby the message changes to Have a Baby, but for any other selection. The message stays the same (nothing), but this isn't working. Can someone please help. Please play with my jsfiddle.

http://jsfiddle.net/Z9YJR/ Here is the html

<select id="leave">
  <option value="5">Get Married</option>
  <option onchange="changeMessage()" value="100">Have a Baby</option>
  <option value="90">Adopt a Child</option>
  <option value="15">Retire</option>
  <option value="15">Military Leave</option>
  <option value="15">Medical Leave</option>
</select>

<div id="message"></div>

Here is the js

function changeMessage() {
    document.getElementById("message").innerHTML = "Having a Baby!!";
}

Something like this should do the trick

<select id="leave" onchange="leaveChange()">
  <option value="5">Get Married</option>
  <option value="100">Have a Baby</option>
  <option value="90">Adopt a Child</option>
  <option value="15">Retire</option>
  <option value="15">Military Leave</option>
  <option value="15">Medical Leave</option>
</select>

<div id="message"></div>

Javascript

function leaveChange() {
    if (document.getElementById("leave").value != "100"){
        document.getElementById("message").innerHTML = "Common message";
    }     
    else{
        document.getElementById("message").innerHTML = "Having a Baby!!";
    }        
}

A shorter version and more general could be

HTML

<select id="leave" onchange="leaveChange(this)">
  <option value="5">Get Married</option>
  <option value="100">Have a Baby</option>
  <option value="90">Adopt a Child</option>
  <option value="15">Retire</option>
  <option value="15">Military Leave</option>
  <option value="15">Medical Leave</option>
</select>

Javascript

function leaveChange(control) {
    var msg = control.value == "100" ? "Having a Baby!!" : "Common message";
    document.getElementById("message").innerHTML = msg;
}
