[jQuery] Using jQuery in requested file by $.ajax


Is it possible ti use jQuery or JS in file which I get by $.ajax?
For example, I have a file like this file.php:
<?
<div id="my_div_1">

Some text ...

</div>
<div id="my_div_2">

Some text ...

</div>
<div id="my_div_3">

Some text ...

</div>
....
<script type="text/javascript"></script> - use JS ???
....
$("my_container").html("Some text ..."); - use jQuery ???
?>
And I use $.ajax from main_file.php:
$.ajax({
type: "POST",
dataType: "html",
data: "data=" + $("#container").html(),
url: "file.php",
cache: false,
error: function(msg) {alert("Error Saved: " + msg);},
success: function(msg) {alert("container = " + $("#container").html
());},
complete: function() {$.unblockUI();}
});
