本文介绍了Angularjs:大于 ng-repeat 的过滤器的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我正在对 ng-repeat 标签应用大于过滤器.我编写了以下自定义过滤器函数:

$scope.priceRangeFilter = 函数(位置){返回 location.price >= $scope.minPrice;};

我在以下 HTML 代码中使用它:

更新 $scope.minPrice 时触发 ng-repeat 标签刷新的最佳方法是什么?

解决方案

应该是自动的.当 $scope.minPrice 改变时,中继器会自动更新.

function Ctrl($scope, $timeout) {$scope.map = [{名称:'地图1',价格:1}, {名称:'地图2',价格:2}, {名称:'地图3',价格:3}];$scope.minPrice = 0;$scope.priceRangeFilter = 函数(位置){返回 location.price >= $scope.minPrice;};$超时(函数(){$scope.minPrice = 1.5;}, 2000);}

I'm applying a greater than filter to a ng-repeat tag. I wrote the following custom filter function:

$scope.priceRangeFilter = function (location) {
    return location.price >= $scope.minPrice;
};

and I use it in the following HTML code:

<div ng-repeat="m in map.markers | filter:priceRangeFilter">

What is the best way to trigger a refresh of the ng-repeat tag when $scope.minPrice is updated?

解决方案

It should be automatic. When $scope.minPrice is changed, the repeater will be automatically updated.

function Ctrl($scope,  $timeout) {
    $scope.map = [{
        name: 'map1',
        price: 1
    }, {
        name: 'map2',
        price: 2
    }, {
        name: 'map3',
        price: 3
    }];
    $scope.minPrice = 0;
    $scope.priceRangeFilter = function (location) {
        return location.price >= $scope.minPrice;
    };

    $timeout(function () {
        $scope.minPrice = 1.5;
    }, 2000);
}
