javaScript中封装的各种写法示例（推荐）

function hello(){
  var a = 'hello';
  alert(a);
}

$(function(){
 $('#id').click(function(){
  alert('hello');
 })
});

var http = require('http');
http.createServer(function(req,res){
 res.writeHead(200,{'Content-Type':'text/html'});
 res.write('<p>hello</p>');
}).listen(8080);

 (function(){
  star.init = (function(name){
    var e = new Editor(name, Data.toolbarData);
   });
 })();

 var klm = klm || {};

 klm = (function(){

    //第一个写法
    klm.init = function(){

     alert('hello');

    }

    //第二个写法
     klm.browser = (function(ua){
       var b = {
        msie:/msie/.test(ua) && !/opera/.test(ua),
        opera:/opera/.test(ua),
        safari:/webkit/.test(ua) && !/chrome/.test(ua),
        firefox:/firefox/.test(ua),
        chrome:/chrome/.test(ua)
       };
      })(window.navigator.userAgent.toLowerCase());

      //将其定义方法以接口方式返回给外界引用

      return{
        init: klm.init,
        browser:klm.browser 
      }

  })();
