Parsley如何停止调用＆＃34; submitForm（）＆＃34;在表单提交期间输入无效时。在这种情况下，＆＃34; task-id＆＃34;不是数字。

Answer 1

希望这段代码能给你一个想法

        <form class="form-horizontal form-label-left parsleyjs"   name="formname" method="post" data-parsley-priority-enabled="false"
            (ngSubmit)="formname.valid && formname.submitForm()">

如果该代码不起作用，则不对此代码进行测试

当输入无效时，Angular 2 Parsley防止表单提交
