var ss=s.split("fs");

for(var i=0;i<ss.length;i++){

处理每一个ss[i];

}

"2:3:4:5".split(":") //将返回["2", "3", "4", "5"]

"|a|b|c".split("|") //将返回["", "a", "b", "c"]

var str = "一二三四";

var str1 = "篮球、排球、乒乓球";

var arr = str.split("");//全部分割

var arr1 = str1.split("、");//按照顿号分割

var arr2 = str1.split("、",2);//按照顿号分割,保留两段
