我试图在弹出框中添加下一个按钮。现在，它以特定顺序运行弹出窗口。同样，当最后一个弹出窗口打开时，该按钮将自动禁用。但是有一个问题当我删除一些模态时，代码不起作用。我想按此顺序运行弹出窗口，当我删除某些弹出窗口时，这些弹出窗口要正确运行。另外，我想创建上一个按钮。我该怎么做？请帮助我解决问题。
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">
<input class="getAssignment" type="button" value="Next">
<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>
<p>You could do a lot of things here like have a pop-up ad that shows when your website loads, or create a login/register form for users.</p>

我不确定这是否是您想要的。但是我尝试重写一下您的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 = '#'
}
})
