 3     //需要将数组元素用某个字符连接成字符串
 4     var a1, b1,c1;
 5     a1 = ["a","b","c","d","e"];
 6     b1 = a1.join(‘-‘); //a-b-c-d-e  使用-拼接数组元素
 7     c1 = a1.join(‘‘); //abcde

12     //实现方法为将字符串按某个字符切割成若干个字符串，并以数组形式返回
13     var str = ‘ab-c-de‘;
14     var a2 = str.split(‘-‘); // [ab, c, de]
15     var b2 = str.split(‘‘); //[a, b, -, c, -, d, e]
