AngularJS-Access $ scope desde el controlador en filtro personalizado (3)
Debe proporcionar el atributo de ámbito deseado al filtro.
Puedes hacerlo así:
Filtrar:
app.filter(''myCustomFilter'', function ($filter) {
return function (date,myVar1) {
/* Do some stuff with myVar1 */
};
});
HTML:
<tr ng-repeat="data in MyData" ng-class="{true: ''green'', false:''red''}[data.Date | myCustomFilter:var1]">
</tr>
Tengo un controller con varios $scopes . Necesito acceder a uno de estos $ scopes en un filtro personalizado:
app.controller(''AppController'',
function($scope) {
$scope.var1 = ''Some data1'';
$scope.var2 = ''Some data2'';
}
);
app.filter(''myCustomFilter'', function ($filter) {
return function (date) {
var date = date;
};
});
<tr ng-repeat="data in MyData" ng-class="{true: ''green'', false:''red''}[data.Date | myCustomFilter]">
</tr>
¿Cómo puedo pasar $ scope.var1 en mi myCustomFilter ?
var app = angular.module(''app'', []);
app.controller(''AppController'',
function($scope) {
$scope.var1 = 2;
$scope.var2 = 3;
$scope.MyData = [{
Date: 1
}, {
Date: 2
}, {
Date: 3
}]
}
);
app.filter(''myCustomFilter'', function($filter) {
return function(date, scopeValue) {
var date = date;
return date * scopeValue
};
});
