定义一个函数，创建HTML列表(arguments)

 1 function list(type) {

 2             var result = "<" + type + ">";

 3 

 4             // iterate through non-type arguments

 5             for (var i = 1; i < arguments.length; i++) {

 6                 result += "<li>" + arguments[i] + "</li>";

 7             }

 8 

 9             result += "</" + type + ">"; // end list

 

             return result;

         }

         var listHTML = list("ul", "One", "Two", "Three");

         // listHTML is "<ul><li>One</li><li>Two</li><li>Three</li></ul>"

         console.log(listHTML);

You can pass any number of arguments to this function
