动态地改变滤波器前pression [英] dynamically change the filter expression

问题描述

我有一个记录数组。此阵列将显示基于用户的权限不同的记录。

I have an array of records. This array will display different records based on the user's permissions.

因此​​，我不得不使用基于用户不同的过滤器。如何创建这样一个前pression这需要根据用户的权限的可变功能 -

Thus I have to use a different filter based upon the user. How do i create such an expression which takes a variable function based on the user's permission -

<div ng-repeat="r in records | filter:{isVisible:true}"

上面有一个过滤器前$ P $ {pssion可见性：真实}。我想，动态地分配根据用户不同的过滤器的前pression。因此，用户2将有{isCommon：M2}。

The above has a filter expression {isVisible:true}. I want to dynamically assign a different filter expression based on the user. So user2 will have {isCommon: 'M2'}.

推荐答案

过滤前pressions可变数太多：

Filter expressions can be variables too:

<li ng-repeat="item in items | filter:filterExpr">{{item.name}}</li>

凡恩pression是在范围定义的：

Where the expression is defined on the scope:

$scope.filterExpr = { tester: true };
