Javascript 匿名函数

今天学习了，

// 例1

/*var util = new Object();
(function(obj){
util.onInit=function(){
$("#btn").click(function(event){
event.stopPropagation();
$("#num").val(1);
});
};
})(util);*/

//例2
/*(function(window, document, undefined){
  var util = window.util = {
onInit: function() {
// TODO

},
showMsg: function() {
//TODO 
}
  };
})(window, document);*/

//例3，推荐

;(function ( $, window, document, undefined ){

var util = window.util = {
onInit: function() {
// TODO

},
showMsg: function() {
//TODO 
}
  };

})(jQuery, window,document);

  


$(function(){
util.onInit();

});
