引导程序模式事件-等待回调完成,然后返回

我知道这个问题听起来很幼稚,但没有想到其他标题。

我正在使用bootstrap modal事件hide.bs.modal中的一个,该事件在模式消失之前被调用,以显示确认框。回调需要一个布尔值。

$('#the-modal').on('hide.bs.modal',function () {
   var self = this;

   $.cofirm("are your sure you want to close",function() { // gets fired if confirmed
       $(self).modal("hide"); // cannot do this,it will fire the event hide.bs.modal over and over.
   });

   return false; // obviously,this gets called first,but that's alright
}

我不是使用传统的confirm,而是使用具有自己回调的jquery插件。

$(self).modal("hide");无法做到这一点,它将一再触发事件hide.bs.modal

您需要标记以了解访客是否确认了它。您可以通过这种方式(使用元素的数据)做到这一点:

$('#myModal').on('hide.bs.modal',function() {
    var thisModal = $(this);
    var thisConfirmed = thisModal.data('confirmed');
    if (!thisConfirmed) {
        $.confirm({
            title: 'Are you sure?',content: '',buttons: {
                confirm: function() {
                    thisModal.data('confirmed',true);
                    thisModal.modal('hide');
                },cancel: function() {
                    /* Nothing here */
                }
            }
        });
        return false;
    } else {
    	thisModal.data('confirmed',false);
        return true;
    };
});

也在JSFiddle上。
