我正在尝试为项目自定义密码强度计,但我不断收到 Javascript/jQuery 中的 RegEx 语法无效的量词错误。我试过转义反斜杠,消除正斜杠,在堆栈和谷歌上搜索。我找到了一些关于此的信息,但他们的解决方案似乎对我没有帮助。我希望有人可以在下面的函数代码中发现它。您的帮助将不胜感激。
$('#rPassword').keyup(function() {
return passwordChanged();
});
function passwordChanged()
{
var pwd = $('#rPassword').val();
var noofchar=/^.*(?=.{3,}).*$/;
var checkspace=/\s/;
var best = /(?=^.{8,}$)(?=.*\d)(?=.*\W+)(?![.\n])(?=.*[A-Z])(?=.*[a-z]).*$/; // 8 character minimum, upper-case letter, Lower-case letter, digit, special character
var strong = /(?=^.{8,}$)((?=.*\d)|(?=.*\W+))(?![.\n])(?=.*[A-Z])(?=.*[a-z]).*$/; // 8 character minimum, upper-case letter, lower-case letter, digit or special character. Examples: “15NotEasy”,”Bett.er-Yet”
var weak = /(?=^.{6,}$)(?=.*\d)(?=.*[A-Za-z]).*$/; // 6 character minimum, upper-case letter or lower-case letter, digit. Examples: “common1″,”7etmein”
var bad = /[a-zA-Z0-9\_\-]{3,}$/; // 3 characters or longer, digits, upper or lower case letters. Examples: “easy”,”8892″,”NOTSECURE”
if (true==checkspace.test(pwd)) {
$('#rPasswordStrength').animate({
width: '0%',
backgroundColor: '#eb001f'
}, 500)
} else if (false==noofchar.test(pwd)) {
$('#rPasswordStrength').animate({
width: '0%',
backgroundColor: '#eb001f'

} else if(best.test(pwd)) {
