依照指定间隔，向字符串中插入随机字符串

按照指定间隔，向字符串中插入随机字符串

var getNewString = function (){    var getIc = function (ic){        var arric = ic.split(",");        randomIc = arric[Math.floor(Math.random()*(arric.length))];        return randomIc    };        return function (oc,ic,re){            var reStr = "(.{"+re+"}|.*)";         var reg = new RegExp(reStr,"g");                 var ocArray = oc.match(reg)                 var arrLength = ocArray.length+1;         for(var element=0;element<arrLength;element+=2){             ocArray.splice(element+1,0,getIc(ic))                            }         return ocArray.join("");    }}();var firstInput = "我们的祖国是花园，花园的花朵真鲜艳。";var secondInput  = "%%%%%%%,&&&&&&&&&,##########,@@@@@@@@@";var interval = 5;alert(getNewString(firstInput,secondInput,interval));
