Question

jquery 给字符串每隔两个字符添加一个分隔符 例如123456 分割成12,34,5

Answer 1

var str = "123456", result = "";
for(var i=0,len=str.length;i<len;i++){
    result += str[i];
    if(i % 2 == 1) result += ',';
}
alert(result);

普通的 javascript 就可以做到，:)

Answer 2

var string = 'abcdefg';
var abc = substring(0,2);
var abcd = substring(2,4);
var abcde = substring(4,6);
var bigString = abc+','+abcd+','+abcde;
