应用更改字符的过滤器后按名称过滤

I've come across a situation where I need to filter elements created by the 'ng-repeat' directive, but I've applied a custom filter that swaps one character by another and vice versa, for each created element.

我遇到过一种情况，我需要过滤'ng-repeat'指令创建的元素，但我已经为每个创建的元素应用了一个自定义过滤器，将一个字符交换为另一个字符，反之亦然。

Then, if I search for the new character that was swapped, the filter won't find it - unless I search for the old one.

然后，如果我搜索交换的新字符，过滤器将找不到它 - 除非我搜索旧字符。

How do I apply this input filter after using my custom filter which swaps characters?

在使用交换字符的自定义过滤器后，如何应用此输入过滤器？

In my custom filter brNumber, dots are swapped by commas and vice-versa, so if I search for a dot the filter will find only the ones with comma.

在我的自定义过滤器brNumber中，点用逗号交换，反之亦然，因此如果我搜索一个点，过滤器将只找到带逗号的点。

You can wrap a filtered value in same function as a filter in view. Check this https://jsfiddle.net/5Lcafzuc/3/

您可以将筛选值包装在与视图中的筛选器相同的函数中。检查这个https://jsfiddle.net/5Lcafzuc/3/

/// wrap filter argument in function
ng-repeat="i in person | orderBy: 'firstName' | filter: replace(firstName)"

/// add function in scope and use it in display filter
var replace = function(text) {        
         if(!text) {
           return false;
         }         

         if(text.indexOf(".") >= 0) {
           text = text.replace(".", ",");
         } else if(text.indexOf(",") >=0) {
           text = text.replace(",", ".");
         }

         return text;
      }

app.controller('myCtrl', function($scope) {    
    $scope.replace = replace;
});

app.filter( 'brNumber', function() {
    return function(text) {        
         return replace(text);
    }
});
