Question

$ brew info python2

... snip ...

=> Caveats
This formula installs a python2 executable to /usr/local/bin.
If you wish to have this formula's python executable in your PATH then add
the following to ~/.bash_profile:
  export PATH="<... some path ...>:$PATH"

... snip ...

我想要结果[{“po”：1}，{“po”：11}，{“po”：12}，{“po”：13}，{“po”：21}] 当我调用$ scope.searchPo（1）;

时

非常感谢

Answer 1

您也可以使用_.filter编写自己的函数。这是一种方法

  var searchPo = function (arr, id) {
   var newarr = []
   var reg = new RegExp(id)
   _.filter(arr, function(value) {
     _.filter(value, function(val) {
       _.each(val, function(v) {
              //console.log(reg.test(v));
             if(reg.test(v)) {
                   newarr.push(val);
             }
       });

     });  
  });

  console.log(newarr);
};

searchPo（a，1）

Answer 2

angular.module('app', [])
.controller('ctrl', ['$scope', '$filter', function($scope, $filter) {
    $scope.array = [
      [{"po":1},{"po":2},{"po":3}],
      [{"po":11},{"po":12},{"po":13}],
      [{"po":21},{"po":22},{"po":23}]
    ];

    $scope.searchPo = function(id){
      return $scope.array.reduce(function(a,b){
        return a.concat($filter('filter')(b, {po: id}));
      }, []);
    }        
   
}])

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>

<ul ng-app='app' ng-controller='ctrl'>
   <li ng-repeat='item in searchPo(1)'>{{item}}</li>
</ul>
