If you are using HTML5 you can use the pattern and required attributes for the input tag:

(如果您使用的是HTML5，则可以为input标签使用模式和必需的属性：)

<input type="password" pattern=".{8,}"   required title="8 characters minimum">
<input type="password" pattern=".{8,12}" required title="8 to 12 characters">

Also there is a minlength attribute for input tags but it does not work in some browsers :

(输入标签也有一个minlength属性，但在某些浏览器中不起作用：)

<input type="password" minlength="8" required>
