jquery怎么判断元素是否在数组中

$(function () {

          var array = ["asp.net", "asp.net mvc", "html5", "css3", "jquery", "JavaScript"];

             var index = $.inArray("asp.net mvc", array);   //结果：index=1

            if (index >= 0) {

                console.log("数组array包含asp.net mvc下标为：" + index);

           } else {

                console.log("数组array 不包含asp.net mvc下标为：" + index);

           }

      });
