Angularjs 如何在alt中验证输入电子邮件？

我使用Angular JS中的foloowing库：

如何验证电子邮件类型的自动完成输入？如果未验证以显示错误

我试图使用

field required=“true”

，但id在电子邮件中无法验证：

<angucomplete-alt
                              placeholder="<%= t('projects.project_full.invitation.enter_email_title') %>"
                              pause="100"
                              id="ex8b"
                              selected-object="selectedInvitationUsers"
                              local-data="invitable_users"
                              search-fields="fullname,email"
                              title-field="fullname,email"
                              minlength="1"
                              input-name="invite.email"
                              override-suggestions="true"
                              input-changed="inputChangeHandler"
                              field-required="true"
                              input-class="form-control form-control-small"/>
                        </div>

将元素指令更改为属性样式，例如：

<div angucomplete-alt
                              placeholder="<%= t('projects.project_full.invitation.enter_email_title') %>"
                              pause="100"
                              id="ex8b"
                              selected-object="selectedInvitationUsers"
                              local-data="invitable_users"
                              search-fields="fullname,email"
                              title-field="fullname,email"
                              minlength="1"
                              input-name="invite.email"
                              override-suggestions="true"
                              input-changed="inputChangeHandler"
                              field-required="true"
                              input-class="form-control form-control-small"/>
                        </div>

您是否将其包装在表单中？是的，我包好了
