JS正则表达式验证密码格式的集中情况总结

 1.密码必须为6-18位字母、数字、特殊符号的：

var reg =/^(?=.*[a-za-z])(?=.*\d)(?=.*[~!@#$%^&*()_+`\-={}:";'<>?,.\/]).{6,18}$/;

2.密码必须为6-18位字母、数字

var reg=/^(?![^a-za-z]+$)(?!\d+$)/

3.支持字母、数字、标点符号、特殊字符

var reg=/^(?:(?=.*[a-z])(?=.*[a-z])(?=.*[0-9])|(?=.*[a-z])(?=.*[a-z])(?=.*[^a-za-z0-9])|(?=.*[a-z])(?=.*[0-9])(?=.*[^a-za-z0-9])|(?=.*[a-z])(?=.*[0-9])(?=.*[^a-za-z0-9])).{6,}|(?:(?=.*[a-z])(?=.*[a-z])|(?=.*[a-z])(?=.*[0-9])|(?=.*[a-z])(?=.*[^a-za-z0-9])|(?=.*[a-z])(?=.*[0-9])|(?=.*[a-z])(?=.*[^a-za-z0-9])|(?=.*[0-9])(?=.*[^a-za-z0-9])|).{6,}$/
