can't access variables in another javascript file

can't access variables in another javascript file

So i have link every file needed into the index.html file :
<script src="jquery.js"></script>
<script src="notify.js"></script>
<script src="script.js"></script>
i create an object in 'notify.js' :
var notify = {
newNotification : function(text) {
}
}
script.js :
alert(notify.newNotification);
When i try to access the 'notify' object in 'script.js', it works just
fine.But i want to use jquery so i add $(document).ready() to both of the
file like this:
notify.js
$(document).ready (
function() {
var notify = {
newNotification : function(text) {
}
}
}
)
Script.js:
$(document).ready (
function() {
alert(notify.newNotification);
}
)
And after i add that, it comes up with notify is not defined.What's wrong?
Can anyone explain why it doesn't work?
