Question

将div过期代码应用于模式时，我遇到了问题。当某些模式过期时，我需要跳过过期的div以及下一个和上一个按钮正常工作。请帮助我解决问题。

这是我使用的js代码。

$(document).ready(function() {
  $(".getAssignment2").click(function() {
   var pNode = $(this).closest(".modalDialog"),
       id = pNode.prev(".modalDialog").attr("id") ||
         $('.modalDialog').last().attr("id");
   window.location.href = "#" + id;
 });
 $(".getAssignment").click(function() {
   var pNode = $(this).closest(".modalDialog"),
       id = pNode.next(".modalDialog").attr("id") ||
         $('.modalDialog').first().attr("id");
   window.location.href = "#" + id;
 });
});

$(function() {

  var current_date = new Date();

    $(".with-expiry").each(function() {
        var div_date = $(this).data('expiry');

      // wrap in Date class
      div_date = new Date(div_date);

        if(current_date.getTime()>div_date.getTime()){
                $(this).hide();
      } else {
        $(this).show();
      }
  });

})

将类添加到过期的模态中，使用nextAll或prevAll检查它们，然后在返回的列表中选择两个函数中的第一个元素。

$(document).ready(function() {
  $(".getAssignment2").click(function() {
   var pNode = $(this).closest(".modalDialog:not(.expired)");
       id = pNode.prevAll(".modalDialog:not(.expired)").first().attr("id") ||
         $('.modalDialog').last().attr("id");
   window.location.href = "#" + id;
 });
 $(".getAssignment").click(function() {
   var pNode = $(this).closest(".modalDialog:not(.expired)");
       id = pNode.nextAll(".modalDialog:not(.expired)").first().attr("id") ||
         $('.modalDialog').first().attr("id");
   window.location.href = "#" + id;
 });
});

$(function() {

  var current_date = new Date();
  
	$(".with-expiry").each(function() {
      var div_date = $(this).data('expiry');
      
      // wrap in Date class
      div_date = new Date(div_date);
  
  		if(current_date.getTime()>div_date.getTime()){
		  $(this).hide();
          $(this).addClass('expired');
      } else {
      	  $(this).show();
          $(this).removeClass('expired');
      }
  });
})

.modalDialog {
