javascript基础知识点（with）2

一、with 语句的作用是将代码的作用域设置到一个特定的对象中

         <script type="text/javascript">var box = new Object();box.name = "xiaoyezi";box.age = 14;with(box){ //在里面操作可以省略前缀boxvar name1 = name; //相当于 var name1 = box.namevar age1 = age;  //相当于 var age1 = box.age}alert(name1+"=="+age1);  //输出的结果是xiaoyzi+"=="+14</script>
