单一全局变量
<script type="text/javascript">
var myApplication = (function () {
function(){
//...
},
return{
//...
}
})();
</script>
前缀命名空间
<script type="text/javascript">
var myApplication_propertyA = {};
var myApplication_propertyB = {};
function myApplication_myMethod(){
//...
}
</script>
我们就简单的介绍过IIFE (即时调用的函数表达式) ，它是一个未命名的函数，在它被定义之后就会立即执行。
如果听起来觉得耳熟，是因为你以前遇到过并将它称之为自动生效的（或者自动调用的）匿名函数，然而我个人更认为 Ben Alman的 IIFE 命名更准确。在JavaScript中，因为在一个作用域中显示定义的变量和函数只能在作用域中可见，
函数调用为实现隐私提供了简单的方式。
<script type="text/javascript">
// an (anonymous) immediately-invoked function expression
(function () { /*...*/})();
// a named immediately-invoked function expression
(function foobar () { /*..*/}());
// this is technically a self-executing function which is quite different
function foobar () { foobar(); }
</script>
嵌套命名空间
<script type="text/javascript">
var application = {
utilities:{
drawing:{
canvas:{
2d:{
//...
}
}
}
}
};
</script>
</body>
</html>
