使用javaScript进行密码验证，无法正常工作

Question

这是我使用JavaScript进行的电子邮件地址验证，我只有两个条件有效，带有特殊字符的条件无效
只有第三个测试电子邮件地址，前两个测试密码。请帮帮我。

<script type = "text/javascript"> 
function validateEmail(form) {
var tr = /[A-Za-z0-9]{8,}/
var tr2 = /S+@S+.S+/  
var tr3 = /[A-Za-z0-9]+[a-zA-Z0-9.!$+/?_]/
if (!(tr.test(form.password.value))){
alert("The passowrd length must be more than 8 letters.")
return false;
}
else if (!(tr3.test(form.password.value))){
alert("Enter a special character.")
return false;
}
else if (!(tr2.test(form.email.value))){
alert("Enter a valid email.")
return false;
}
else{
alert("signed in successfully")
window,open("HomePage.html")
return true
}
}
</script>

只需将regex更改为此即可。

const form = {
password: {
value: 'buffaloBill3#@$',
},
email: {
value: '[e-mail]'
}
};

function validateEmail(form) {
var tr = /[A-Za-z0-9]{8,}/
var tr2 = /S+@S+.S+/
var tr3 = /^(?=.*[!@#$%^&*])[a-zA-Z0-9!@#$%^&*]{0,}$/;

if (!(tr.test(form.password.value))) {
alert("The passowrd length must be more than 8 letters.")
return false;
} else if (!(tr3.test(form.password.value))) {
alert("Enter a special character.")
return false;
} else if (!(tr2.test(form.email.value))) {
alert("Enter a valid email.")
return false;
} else {
alert("signed in successfully")
window, open("HomePage.html")
return true
}
}
validateEmail(form);
