This regex works well for me to validate password:

<pre><code>/[ !"#$%&amp;'()*+,-./:;&lt;=&gt;?@[\\\]^_`{|}~]/

This list of special characters (including white space and punctuation) was taken from here: <a href="https://www.owasp.org/index.php/Password_special_characters" rel="nofollow noreferrer">https://www.owasp.org/index.php/Password_special_characters</a>. It was changed a bit, cause backslash ('\') and closing bracket (']') had to be escaped for proper work of the regex. That's why two additional backslash characters were added.

I'm trying to create a validation for a password field which allows only the <code>a-zA-Z0-9</code> characters and <code>.!@#$%^&amp;*()_+-=</code>

I can't seem to get the hang of it.

What's the difference when using <code>regex = /a-zA-Z0-9/g and regex = /[a-zA-Z0-9]/</code> and which chars from <code>.!@#$%^&amp;*()_+-=</code> are needed to be escaped?

What I've tried up to now is:

<pre><code>var regex = /a-zA-Z0-9!@#\$%\^\&amp;*\)\(+=._-/g
</code></pre>

but with no success

javascript regex for special characters

我正在尝试为只允许a-zA-Z0-9字符和.!@#$%^&*()_+-=的密码字段创建验证我似乎不能掌握它的诀窍。使用regex = /a-zA-Z0-9/g and regex = /[a-zA-Z0-9]/时有什么区别，.!@#$%^&*()_+-=中的哪些字符需要转义？到目前为止，我尝试的是：var regex = /a-zA-Z0-9!@#\$%\^\&*\)\(+=._-/g但是没有成功
