You can extend the jquery object yourself with the extend method and then use those methods you created as if it were any other jquery object.
To extend an existing JQuery object in your javascript by doing the following.
<script type="text/javascript" language="javascript">
(
function($) {
function DoMyFunction1(response) {
}
function DoMyFunction2(response) {
}
$.extend({
DoFunction1: function(response) { DoMyFunction1(response); },
DoFunction2: function(response) { DoMyFunction2(response); }
});
})($);
</script>
To use the JQuery extended functions:
$.DoFunction1(myArg);
$.DoFunction2(myArg);
