<script type="text/javascript">
        var n1=1;
        var n2=1.11;
        var n1=String(n1);
        var n2=n2.toString();
        document.write("n1的值是:" + n1+ "<br>" + "n1的类型是:"+typeof(n1) + "<br>");
        document.write("n2的值是:" + n2+ "<br>" + "n2的类型是:"+typeof(n2));
       /*页面输出
        n1的值是:1
        n1的类型是:string
        n2的值是:1.11
