JS-Array数组内置对象
直接上代码：
1 <!DOCTYPE html> 2 <html> 3 <head> 4 <meta charset="UTF-8"> 5 <title>uvi</title> 6 <link rel="stylesheet" href="style.css" type="text/css"> 7 </head> 8 <body> 9 <script> 10 var a=["hello","world"]; 11 var b=["uvi","ivu"]; 12 var c=a.concat(b);//数组合并 13 document.write(c); 14 15 var d=["1","3","4","5","2","6"]; 16 document.write(d.sort());//数组排序 17 18 document.write(d.sort(function(a,b){ 19 return b-a; 20 }));//数组降序 21 22 23 var e=["a","b"]; 24 e.push("c")//数组的末尾追加字符 25 document.write(e); 26 27 var f = ["c","b","a"]; 28 document.write(f.reverse());//数组的反转 29 </script> 30 <div id = "timetxt"></div> 31 32 </body> 33 </html>
