没研究过有一个就可以解决 的，但同个却有，
function checkPS(ps) {
var len = 0;
if(ps.length >= 6) {
var rs = /[A-Z]/;
if(rs.test(ps)) {
len++;
}
rs = /[a-z]/;
if(rs.test(ps)) {
len++;
}
rs = /[0-9]/;
if(rs.test(ps)) {
len++;
}
rs = /[^A-Za-z0-9]/;
if(rs.test(ps)) {
len++;
}
}
return len >= 3;
}
var ps = 'ZD5007 = $qt$#ZD5019$qt$ and isnull(ZFBZ,0)=0 and ';
checkPS(ps);
