javascript - 如何在弹出窗口上添加下一个上一个按钮？

问题描述

我试图在弹出框上添加下一个按钮。现在它以特定顺序运行弹出窗口。此外，当最终弹出窗口打开时，按钮会自动禁用。但有一个问题。当我删除一些模式时，代码不起作用。我想按该顺序运行弹出窗口，当我删除一些弹出窗口时，弹出窗口希望正确运行。另外，我想创建上一个按钮。我该怎么做？请帮我解决这个问题。

这是我使用的代码。

$(document).ready(function() {
   var currentmodal = 1;
   $(".getAssignment").click(function() {
      var $divs = $(".modalDialog");
      var modal = $("*[data-modalorder="+(currentmodal++)+"]");
      if(!$("*[data-modalorder="+currentmodal+"]").length)
      {
          modal.find("input.getAssignment").prop("disabled",true);
      }
      if ($divs.length > 0 && modal) {
          window.location.href = "#" + $(modal).attr("id");
      }
   });
});

$(document).ready(function() {
       var currentmodal = 1;
       $(".getAssignment2").click(function() {
          var $divs = $(".modalDialog");
          var modal = $("*[data-modalorder="+(currentmodal--)+"]");
          if(!$("*[data-modalorder="+currentmodal+"]").length)
          {
              modal.find("input.getAssignment2").prop("disabled",true);
          }
          if ($divs.length > 0 && modal) {
              window.location.href = "#" + $(modal).attr("id");
          }
       });
    });

<input class="getAssignment" type="button" value="Open Modal">

<div id="openModal" class="modalDialog" data-modalorder=1>
    <div>
    <input class="getAssignment2" type="button" value="Previous">

    <a href="#close" title="Close" class="close">X</a>
   <h2>Modal Box 1</h2>
        <p>This is a sample modal box that can be created using the powers of CSS3.</p>

解决方案

我不确定这是否是您想要的。但我试着重写你的js。

$(document).ready(function() {
	var data=[];
  currentModal = 0;
  
  $('.modalDialog').each(function(){
    data.push({
      id: $(this).attr('id'),
      order: $(this).data('modalorder')
    });
  })
    
	$('#openModalBtn').click(function(){
  	currentModal = 0;
    window.location.href = "#" + data[currentModal].id;
    $('#'+data[currentModal].id).find('.getAssignment2').prop('disabled', true);
  })
  
  //prev
  $('.getAssignment2').click(function(){
  	if (currentModal>0) {
    	currentModal--;
      window.location.href = "#" + data[currentModal].id;
    } else {
      
    	window.location.href = '#'
    }
  })
  
  //next
  $('.getAssignment').click(function(){
  	if (currentModal<data.length - 1) {
    	currentModal++;
      if (currentModal===data.length - 1) $('#'+data[currentModal].id).find('.getAssignment').prop('disabled', true);
      window.location.href = "#" + data[currentModal].id;
    } else {
    	window.location.href = '#'
    }
  })
