使用角度，我想在单击保存按钮时使用指令将输入的值保存到 cookie 中。这是我的代码，我不确定是否应该使用链接函数或控制器指令，但无论如何 $cookie 在单击事件处理程序中当然是未知的。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全这样做，请告诉我。
