js中字符串分割成数组split()方法

split -> [splɪt] -> 分裂

省略分割参数：

var str="How are you doing today?";var n=str.split();

How are you doing today? //结果

分割每个字符，包括空格:

var str="How are you doing today?";var n=str.split("");

H,o,w, ,a,r,e, ,y,o,u, ,d,o,i,n,g, ,t,o,d,a,y,? //结果

使用 limit 参数:

var str="How are you doing today?";var n=str.split(" ",3);

How,are,you //结果

使用一个字符作为分隔符:

var str="How are you doing today?";var n=str.split("o");

H,w are y,u d,ing t,day? //结果
