Comment filtrer mes données? (ng-grille)

Je pense que c'est probablement très simple, mais je ne trouve aucune documentation claire sur la façon d'ajouter un filtre en dehors du "filterText" affiché sur leur site Web. Ce que j'essaie de faire est quelque chose d'aussi simple que cela:

$scope.filterOptions = {
    filter: $scope.myFilter,  // <- How to do something like this? 
    useExternalFilter: true
}

$scope.gridOptions = {
        data: 'entries',
        enableColumnResize: false,
        multiSelect: false,
        enableSorting: false,
        selectedItems: $scope.selectedEntries,
        filterOptions: $scope.filterOptions
}

$scope.lowerLimit = 50;
// My Filter
$scope.myFilter = function(entry) { 
    if (entry < $scope.lowerLimit) {
        return false; 
    }
    return true;
 }

Edit: Ou peut-être si je pouvais filtrer la source de données d'une manière ou d'une autre? J'ai essayé ceci:

$scope.gridOptions = {
        data: 'entries | filter: myFilter',
        enableColumnResize: false,
        multiSelect: false,
        enableSorting: false,
        selectedItems: $scope.selectedEntries,
}

Mais il lance pas mal d'erreurs.

J'ai trouvé un moyen qui se met à jour instantanément. Fondamentalement, je détiens un ensemble masqué de toutes mes données, et lors de la réception de nouvelles données ou de la modification de mon filtre - j'applique ce filtre à l'ensemble de données complet et je remets à la grille la version filtrée.

Cela me permet d'utiliser comparateurs (c'est-à-dire l'âge> = 50) dans mon filtre, ce qui est le but de cette question.

// Full unfiltered data set
$scope.entries = []; // Updated and pushed to

$scope.gridOptions = {
    // The grids already filtered data set
    data: 'filteredEntries',
    enableColumnResize: false,
    multiSelect: false,
    enableSorting: false,
    selectedItems: $scope.selectedEntries,
}

 $scope.$on("updateEntries", function(data) {
     // My table is filled by socket pushes, this is where it is updated.
     $scope.updateFilters();
 }

 $scope.$on("newFilter", function(newFilter) {
     // This is where I update my filter
     $scope.updateFilters();
 }

 $scope.updateFilters = function() {
     // Filters the full set and hands the result to the grid. 
     $scope.filteredEntries = $filter('filter')($scope.entries, $scope.myFilter);
     $scope.$digest();
 }         

 // A modifiable limit, modify through newFilter so data is refiltered
 $scope.lowerLimit = 50;

 // My Filter
 $scope.myFilter = function(entry) { 
     if (entry < $scope.lowerLimit) {
        return false; 
     }
     return true;
 }

Vous pouvez utiliser angular pour vous lier au filterOptions.filterText variable. Il y a un plongeur ici pour démontrer: http://plnkr.co/edit/PHdBhF?p=preview

Je posterai le même code ci-dessous:

    // main.js
    var app = angular.module('myApp', ['ngGrid']);
    app.controller('MyCtrl', function($scope) {
      $scope.filterOptions = {
        filterText: ''
      };

      $scope.myData = [{name: "Moroni", age: 50},
                       {name: "Tiancum", age: 43},
                       {name: "Jacob", age: 27},
                       {name: "Nephi", age: 29},
                       {name: "Enos", age: 34}];

      $scope.gridOptions = {
        data: 'myData',
        filterOptions: $scope.filterOptions
      };
    });

Ce qui précède devrait être à peu près identique aux plongeurs sur la page des documents.

    <!DOCTYPE html>
    <html ng-app="myApp">
        <head lang="en">
            <meta charset="utf-8">
            <title>Custom Plunker</title>

            <script type="text/javascript" src="main.js"></script>
        </head>
        <body ng-controller="MyCtrl">
          <strong>Filter:</strong><input type="text" ng-model="filterOptions.filterText" />
          <br/>
          <br/>
          <div class="gridStyle" ng-grid="gridOptions"></div>
        </body>
    </html>

Remarquer ng-model="filterOptions.filterText" sur le <input ...>. C'est tout ce qu'il faut!

C'est ma solution !!

Il a trouvé avec ng-grid en html:

<input type="text" ng-model="miinput" placeholder="Filter text"/>
<div class="gridStyles" ng-grid="gridOpciones">
</div>

en js:

//pagination
$scope.filterOptions = {
    filterText: $scope.miinput,
    useExternalFilter: true
}; 
$scope.totalServerItems = 0;
$scope.pagingOptions = {
    pageSizes: [10, 25, 50],
    pageSize: 10,
    currentPage: 1
};  
$scope.setPagingData = function(data, page, pageSize){  
    var pagedData = data.slice((page - 1) * pageSize, page * pageSize);
    $scope.vocabulario = pagedData;
    $scope.totalServerItems = data.length;
    if (!$scope.$$phase) {
        $scope.$apply();
    }
};
$scope.getPagedDataAsync = function (pageSize, page, searchText) {
    setTimeout(function () {
        var data;
        if (searchText) {
            var ft = searchText.toLowerCase();
            $http.get('http://localhost:9000/json/voc.json').success(function (largeLoad) {     
                data = largeLoad.filter(function(item) {
                    return JSON.stringify(item).toLowerCase().indexOf(ft) != -1;
                });
                $scope.setPagingData(data,page,pageSize);
            });            
        } else {
            $http.get('http://localhost:9000/json/voc.json').success(function (largeLoad) {
                $scope.setPagingData(largeLoad,page,pageSize);
            });
        }
    }, 100);
};

$scope.getPagedDataAsync($scope.pagingOptions.pageSize, $scope.pagingOptions.currentPage);

$scope.$watch('pagingOptions', function (newVal, oldVal) {
    if (newVal !== oldVal && newVal.currentPage !== oldVal.currentPage) {
        $scope.getPagedDataAsync($scope.pagingOptions.pageSize, $scope.pagingOptions.currentPage, $scope.filterOptions.filterText);
    }
}, true);
$scope.$watch('filterOptions', function (newVal, oldVal) {
    if (newVal !== oldVal) {
        $scope.getPagedDataAsync($scope.pagingOptions.pageSize, $scope.pagingOptions.currentPage, $scope.filterOptions.filterText);
    }
}, true);

//cada vez que escribo en el input
$scope.$watch('miinput', function () {
    if ($scope.miinput !== "") {
        $scope.pagingOptions.currentPage=1;
        $scope.getPagedDataAsync($scope.pagingOptions.pageSize, $scope.pagingOptions.currentPage, $scope.miinput);
    }else{
        $scope.getPagedDataAsync($scope.pagingOptions.pageSize, $scope.pagingOptions.currentPage, $scope.filterOptions.filterText);
    }
}, true);


 //
 $scope.gridOpciones = { 
    data: 'vocabulario',
    showGroupPanel: true,
    enableCellSelection: true,
