我试图将我的应用程序中出现的toast数量设置为6,我正在使用有角度的烤面包机,并且在我的选项中我给了 maxOpened = 5 ,但它对我不起作用 . 我已经设置了这样的选项,

toastr.options = {
        "closeButton": true,
        "debug": false,
        "newestOnTop": false,
        "maxOpened": 5,
        "progressBar": true,
        "positionClass": "toast-top-right",
        "preventDuplicates": false,
        "onclick": onToasterClick,
        "showDuration": "300",
        "hideDuration": "120000",
        "timeOut": "20000",
        "extendedTimeOut": "0",
        "showEasing": "swing",
        "hideEasing": "linear",
        "showMethod": "fadeIn",
        "hideMethod": "fadeOut"
    };

我想知道有没有办法将它设置为5 .
