js生成一个以零开头的八位数并且依次递增

条件：1八位数；2.以领开头；3.末尾要依次递增

<script type="text/javascript">

function RondomPass(number){

    var arr = new Array;

    var arr1 = new Array("0","1","2","3","4","5","6","7","8","9");

for(var i=0;i<number;i++){

        var n = Math.floor(Math.random()*10);

        arr[i] =arr1[n] ;

        //document.write(arr1[n]);

    }
val = arr.join("")

    //document.write(val);

    return val;

}
function Account(num,a){     // num以领开头的8位数，a依次递增

    //初始的a为数字

    var s = a.toString();   // 数字转字符串

    var b =s.split("");    //字符串转数组

    var c = num-b.length;

    var e= new Array;

    for(var i=0;i<c;i++){

        e[i] = 0;

    }

    var f = e.join("");    //数组转字符串
return f;

}
var num = ‘30‘;

for(var i=0;i<num;i++){

    document.write("账户");

    document.write(Account(8,i)+i);

    document.write("&nbsp;&nbsp;");
document.write("密码");

    document.write(RondomPass(8));

    document.write("</br>");

}
