javascript当中Function用法
4）Function用法 例 3.4.1 <head> <meta http-equiv="content-type" content="text/html; charset=utf-8"/> </head> <script> /*马克-to-win：When the Global object is created, it always has at least the following properties: Object object Function object Array object String object Boolean object Number object Date object Math object Value properties */ /*Function的好处是， 函数体可以是运行时的一个传入的动态字符串，for the Function class, the last parameter is function body, while the parameters before the last one are input arguments., 'x' can be changed to "x" */ var a='return x + y;'; var f = new Function('x', 'y',a );// 等价于var f = function(x, y){return x + y;} document.write(f(1, 1)); </script>
