Angular 表单验证但没有 <form>？

Question

我正在尝试使用 angular material 框架获得一个非常简单的 angular 验证表单。我正在 Sharepoint 2010 内容编辑器 Web 部件中构建此表单，该表单允许使用 .我正在努力重建表格而不是在网页上，但没有涉及其他更复杂的问题。

但我深入探讨了其他问题，我只是想知道 angular 验证表单是否可以在没有该元素的情况下工作？或者是否有其他指令可以替代它？

这是我的目标但没有表单元素的一个小例子。

</div>

有人知道这方面的信息吗？没能找到这方面的文档。

AngularJs ngForm direcive 不要求元素必须是 <form>，如果您愿意，可以在 div 中使用 ng-form。例如，取自您的 fiddle，您用这个 div 替换了之前的 form 元素。

<div ng-form="frm" class="pure-form pure-form-aligned">
...
</div>
