Question

我想对表行进行验证，我是按照以下方式进行的，但它不起作用。我想在lst。点击保存按钮时应用它。

我有5列并希望对每列应用验证假设任何字段为空我想要禁用该按钮。有人可以帮忙吗？

Answer 1

这里可能有问题的一点是按钮超出了ng-repeat的范围。所以它不知道mappingElement。如果要在每行上单独验证，请在列中添加按钮，
否则你可以在控制器中创建一个函数来迭代formIdMetadataMappingToObjectMap[currentForm.unique_id].mappingElements集合并搜索空值，然后你只需将它添加到按钮ng-disabled="validationFunc()"。
