Try using the :passwordselector as it will make your code shorter:
尝试使用:password选择器，因为它会使您的代码更短：
$(':password').val('');
Also your initial code should work. Your problem is somewhere else. Unfortunately as you haven't stated in what context and how this is called or as you haven't explained what it doesn't workmean I cannot help you further.
您的初始代码也应该可以工作。你的问题在别处。不幸的是，由于您没有说明在什么上下文中以及如何调用它，或者您没有解释它不起作用的原因，这意味着我无法进一步帮助您。

Detailed Answer
详细解答
:password Selector( from jQuery document )
:password 选择器（来自 jQuery 文档）
Description: Selects all elements of type password.
描述：选择密码类型的所有元素。
version added: 1.0
添加的版本：1.0
jQuery( ":password" )
jQuery(":密码")
$( ":password" ) is equivalent to $( "[type=password]" ).
$( ":password" ) 等价于 $( "[type=password]" )。
As with other pseudo-class selectors (those that begin with a ":") it is recommended to precede it with a tag name or some other selector; otherwise, the universal selector ( "*" ) is implied.
与其他伪类选择器（那些以“:”开头的选择器）一样，建议在它前面加上标签名或其他选择器；否则，将隐含通用选择器 ( "*" )。
In other words, the bare $( ":password" ) is equivalent to $( "*:password" ), so $( "input:password" ) should be used instead.
换句话说，裸 $( ":password" ) 等效于 $( "*:password" )，因此应该使用 $( "input:password" ) 代替。
Additional Notes:
补充说明：
Because :password is a jQuery extension and not part of the CSS specification, queries using :password cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. For better performance in modern browsers, use [type="password"] instead.
因为 :password 是 jQuery 扩展而不是 CSS 规范的一部分，所以使用 :password 的查询无法利用原生 DOM querySelectorAll() 方法提供的性能提升。为了在现代浏览器中获得更好的性能，请改用 [type="password"]。
