Html 当显示其他错误消息时，是否有可能隐藏错误消息？

在这段代码中，如果我用空格键入少于6个字符，它会显示两个密码都应该至少有6个字符不允许空白

---

我不想同时显示两条错误消息，应该只显示一条错误消息

如果两个条件都满足，您需要决定显示哪一个

 <form name="form">
     <input type="password" placeholder="Password" ng-model="password" name="password" minlength="6"  maxlength="15" ng-pattern="/^\S*$/" required>
     <span ng-show="form.password.$dirty && form.password.$invalid">
       <span ng-show="form.password.$error.required">Password is required.</span>
       <span ng-show="form.password.$error.minlength">Password should have atleast 6 characters.</span>
       <span ng-show="form.password.$error.pattern">White Space not allowed.</span>
     </span>
 </form>

如果你有第三个

<span ng-show="form.password.$error.minlength">Password should have atleast 6 characters.</span>
<span ng-show="form.password.$error.pattern && !form.password.$error.minlength">White Space not allowed.</span>

<span ng-show="form.password.$error.patternQ 
    && !form.password.$error.pattern 
    && !form.password.$error.minlength">Question mark not allowed.</span>
