我有这段代码:
<tbody ng-repeat="term in Items | filter:searchText track by term.Element">
<tr class="term-row">
<td ng-show="!IsValid(term)" class="text-center">
<img ng-show="GetStatus(term)==''" src='@Url.Content("~/Lib/img/spinner26x26.gif")' />
<span class="label label-danger">Invalid</span>
</td>
<td ng-show="IsValid(term)" class="text-center">
<img ng-show="GetStatus(term)==''" src='@Url.Content("~/Lib/img/spinner26x26.gif")' />
<span class="label label-success" ng-bind="GetStatus(term)"></span>
</td>
</tr>
正如您所看到的,我在迭代通过转发器时在几个地方调用了IsValid(item)。是否可以将该方法的结果存储在本地的转发器变量中,然后使用结果而不是调用函数x次? 谢谢!

您可以使用ng-init:
<tbody ng-repeat="term in Items | filter:searchText track by term.Element" ng-init="isValid = IsValid(term)">
然后使用该值
<td ng-show="!isValid" class="text-center">
<td ng-show="isValid" class="text-center">
