复制代码 代码如下:

var lishustr = "qwertyuiopasdfghjklmnbvcxz";

var s = lishustr.split("");

var lishua = ""; var lishub = ""; var lishuc = ""; var lishud = "";

lishua = s[getRandomNum(1,26)]; lishub = s[getRandomNum(1,26)]; lishuc = s[getRandomNum(1,26)]; lishud = s[getRandomNum(1,26)];

switch ("abcdefghijklmnopqrstuvwxyz".indexOf(lishud) + 1) {

case 1: case 2: case 3: case 4: case 5: case 6: case 7:

md5words = md5words + lishua + lishub + lishuc + lishud; break;

case 8: case 9: case 10: case 11: case 12: case 13: case 14:

md5words = lishua + md5words + lishub + lishuc + lishud; break;

case 15: case 16: case 17: case 18: case 19: case 20:

md5words = lishua + lishub + md5words + lishuc + lishud; break;

case 21: case 22: case 23: case 24: case 25: case 26:

md5words = lishua + lishub + lishuc + md5words + lishud; break;

}

function getRandomNum(lbound, ubound) {

return (Math.floor(Math.random() * (ubound - lbound)) + lbound);

}
