javascript - 如何在输入验证工具提示消息中插入新行？当悬停时它工作正常但我点击发送它没有

Question

如何在输入工具提示消息中添加新行。我试过 <br>, \n, &nbsp;但它没有用。

<input type="password"  id="password" v-model="user.password" class="form-control"
 title="Must contain at least one number, one uppercase letter, one special character and at least 8 characters"  pattern="(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[!@#\$%\^&\*]).{8,}" required>

希望对你有帮助

只需使用实体代码 作为标题属性中的换行符。

Add line break within tooltips

<form id="myform" >
  <input data-html="true"  type="password"  id="password" v-model="user.password" class="form-control"
 title="Must contain at least one number &#013;
 one uppercase letter &#013;one special &#013; character and at least 8 characters"  pattern="(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[!@#\$%\^&\*]).{8,}" required>
    <input type="submit" />
</form>
