直接上代码吧,你竟然搜到了我的文章就应该知道了,为什么要热更新

//app热更新下载
//假定字符串的每节数都在5位以下
function toNum(a) {
//也可以这样写 var c=a.split(/\./);
var c = a.split('.');
var num_place = ["", "0", "00", "000", "0000"],
r = num_place.reverse();
for(var i = 0; i < c.length; i++) {
var len = c[i].length;
c[i] = r[len] + c[i];
}
var res = c.join('');
return res;
}
