one way:
file1, IIFE.js
(function() {
var jQuery = {
myAlert:function myAlert(){
alert("IIFE Test");
}
};
window.jQuery = jQuery;
})();
file 2,IIFE-test.html
<html>
<script type="text/javascript" src="IIFE.js"></script>
<script type="text/javascript">
jQuery.myAlert();
</script>
</html>
another way:
js codes,
var jQuery = function()
{
var myAlert = function(){
alert("test");
}
return{
myAlert : myAlert
};
}();
omit html codes.
