Question

使用angular，我想在点击“保存”按钮时使用指令将输入值保存到cookie。这是我的代码，我不确定我是否应该使用链接函数或控制器指令，但无论如何$ click当然在click事件处理程序中是未知的。如何将$ cookie或$ log传递给on Click函数？

.directive('ndUserSettingCookie', ['$cookies', '$log',function() {
return {
    link: function(scope, el, attrs) {
        scope.savedMsg = ' items by page';
        var setting = [];
        scope.itemsByPage = 18;
        scope.itemsByPage = (typeof setting.itemsByPage !== "undefined")? setting.itemsByPage :scope.itemsByPage;

        el.on('click', function() {                     

            var now = new Date(),
            // this will set the expiration to 12 months
            expireDate = new Date(now.getFullYear()+1, now.getMonth(), now.getDate());

            $cookies.putObject('setting.itemsByPage', scope.itemsByPage, {'expires': expireDate});
            scope.savedMsg = scope.itemsByPage + " items per page saved to your settings!";

            scope.$apply();
        })
    }
}
}])

如果您认为我应该以另一种方式完成此操作，请告诉我。

抱歉，伙计们，我只是忘了将它们添加到函数参数中！我的坏！

这是它的工作原理：

.directive('ndUserSettingCookie', ['$cookies', '$log',function($cookies, $log) {

角度将$ cookie传递给指令中的click事件
