Question

我有一个搜索字段，我想对它应用一个过滤器，我希望我的json数据被多个参数搜索，我想以这样的方式指定参数，以便我可以在时间更改它们api调用，这里的代码按名称和分支类别，但我只能按名称搜索，我不知道如何解决它，请帮助

这是我的代码

你刚刚错过了model.object：

使用 过滤器：search.name ：

<li ng-repeat="item in filtered = items | filter:search.name | startFrom:(currentPage-1)*entryLimit | limitTo:entryLimit">{{item.name}}  {{item.branch}}</li>

如何在单个搜索框中使用角度中的多个参数进行搜索？
