js字串函數之split（）join（）

標籤：

split方法用於把一個字串切割成字串數組，與join相反

一個參數表示以該參數為切割點，

1     var str="silence‘s world";2     console.log(str.split(" "));// ["silence‘s", "world"]3     console.log(str.split("‘"));// ["silence", "s world"]4     console.log(str.split(""));//["s", "i", "l", "e", "n", "c", "e", "‘", "s", " ", "w", "o", "r", "l", "d"]5 　　//兩個參數時，後一個參數表示長度6     console.log(str.split("‘",1));// ["silence"]7     console.log(str.split("",5));// ["s", "i", "l", "e", "n"]

join方法用於將數組串連成字串

1 var arr=["s","i","l","e","n","c","e"]2     console.log(arr.join(","));//s,i,l,e,n,c,e3     console.log(arr.join(""));//silence4     console.log(arr.join("."));//s.i.l.e.n.c.e5     console.log(arr.join("|"));//s|i|l|e|n|c|e
