角滤波问题

Question

我有一个使用过滤器的角度应用程序。我的json文件如下所示：

[{DegreeCategoryID:"1",DegreeCategory:"Accounting",DegreeCategoryType:"Applied Sciences"},
{DegreeCategoryID:"2",DegreeCategory:"Advanced Manufacturing/Mechatronics Technology",DegreeCategoryType:"Applied Sciences"},
{DegreeCategoryID:"3",DegreeCategory:"Air Conditioning and Refrigeration Technology",DegreeCategoryType:"Applied Sciences"},
{DegreeCategoryID:"4",DegreeCategory:"Auto Body Technology",DegreeCategoryType:"Applied Sciences"},
{DegreeCategoryID:"77",DegreeCategory:"Associate in Arts",DegreeCategoryType:"Academic"},
{DegreeCategoryID:"78",DegreeCategory:"Associate in Sciences",DegreeCategoryType:"Academic"},
{DegreeCategoryID:"79",DegreeCategory:"Associate of Arts in Teaching",DegreeCategoryType:"Academic"},
{DegreeCategoryID:"80",DegreeCategory:"Emphasis",DegreeCategoryType:"Academic"},
{DegreeCategoryID:"81",DegreeCategory:"Field of Study",DegreeCategoryType:"Academic"}]

我使用的语句使用的过滤器如下：

<a href='#' ng-repeat="degree in degrees | filter:search:Academic" class="list-group-item">
                          <li ng-click="showCourseDescription(p.subchildren)" >{{degree.DegreeCategory}}</li>
                        </a>

但是过滤没有发生。有什么建议吗？

Answer 1

ngRepeat表达式应该如下所示：

ng-repeat="degree in degrees | filter:{DegreeCategoryType:'Academic'}"

更新：

如果要使用搜索字段指定搜索值：

<input type="search" ng-model="search" />
...
<li ng-repeat="degree in degrees | filter:{DegreeCategoryType:search}">

最后，请记住，您可以指定第三个参数，指示您想要的是子字符串匹配还是值的精确匹配：

<input type="search" ng-model="search" />
<input type="checkbox" ng-model="exactMatch" />
...
<li ng-repeat="degree in degrees | filter:{DegreeCategoryType:search}:exactMatch">

看，还有，这个短演示。
