【问题描述】:
我正在加载表单中的数据。我只想在表单有效的情况下允许用户提交数据。最初的形式是原始的但无效。在用户可以编辑的三个字段中,如果他更改任何一个,表单不再是原始的,这没关系,但表单仍然无效..尽管其他字段中的值是有效的。如何绕过在每个字段周围放置 isPristine 和 IsValid 条件?代码如下。我在转发器内有它用于编辑/查看。删除了代码的视图部分,因为我认为它不适用于这种情况。
<table class="table">
<tbody>
<tr ng-repeat="comment in comments | orderBy: 'CreatedDate':true" ng-class-odd="'odd'" ng-class-even="'even'">

<table border="0" class="form-group" ng-show="editComment.CommentID == comment.CommentID">

视情况而定,您可以将字段设置为有效,例如:
editCommentForm.[form_field_name].$setValidity("required", false);
