您可以在此处使用简单的方法验证密码：

<强> HTML：

<form name="myForm" style="padding-top:30px; margin-left:30px"> 
    <label for="password">Password</label>
    <input type="password" id="password" name="password" ng-model="formData.password" ng-minlength="8" ng-maxlength="20" ng-pattern="/(?=.*[a-z])(?=.*[A-Z])(?=.*[^a-zA-Z])/" required />
    <span ng-show="myForm.password.$error.required && myForm.password.$dirty">required</span>
    <span ng-show="!myForm.password.$error.required && (myForm.password.$error.minlength || myForm.password.$error.maxlength) && myForm.password.$dirty">Passwords must be between 8 and 20 characters.</span>
    <span ng-show="!myForm.password.$error.required && !myForm.password.$error.minlength && !myForm.password.$error.maxlength && myForm.password.$error.pattern && myForm.password.$dirty">Must contain one lower &amp; uppercase letter, and one non-alpha character (a number or a symbol.)</span>
    </br></br>
    <button type="submit" class="btn" ng-disabled="!myForm.$valid">Submit</button>
  </form>

“$”在代码块的开头无效。只有标识符，关键字，注释“（”和“{”有效
