javascript - 如何从两个单独的 XML 文件加载数据？

Question

我正在尝试从两个单独的文件加载 XML 数据。在页面加载时，我想默认显示一个文件的数据。页面上会有一个按钮来显示来自下一个文件的数据。

加载 XML 文件后，我需要将所有弹出框与循环结合起来。但是我的代码不支持循环该弹出窗口。我怎样才能实现下面的代码？请帮忙。

这是我的代码。

  $(document).ready(function(){
    $.ajax({
        type:"GET",
        url:"contact.xml",
        dataType:"xml",
        success:xmlParser2
    });
});

function xmlParser2(xml){
    var items = $(xml).children().children();
    items.sort(function() { return 0.5 - Math.random() });
    
    xml = $(xml).children();
    let i = 0;
    let total = $(xml).children().length;
    items.each(function (idx,index,item) {

        let expireArray = $(this).attr('expires').split('/');
        const expireDate = `${expireArray[2]}${expireArray[1]}${expireArray[0]}`;
        const now = new Date(),
            nowDate = `${now.getFullYear()}${(now.getMonth()+1) <10 ? '0'+(now.getMonth()+1): (now.getMonth()+1)}${now.getDate()}`;

        if (nowDate > expireDate) {
            return;
        }      
        
        let tag = $(this).prop("tagName")+index;
        let nextIdx = idx + 1;
        let prevIdx = idx - 1;
        //to make cyclic
        nextIdx = nextIdx == total ? 0 : nextIdx;
        prevIdx = prevIdx == -1 ? (total -1) : prevIdx;

        let image = '<img style="background-image:url(' + $(this).find("image").text() + ')"' + '" />';
        let image2 = '<div><img src="' + $(this).find("image").text() + '" width="100%" alt="' + '" />' + '</div>';
        let head = '<div>' + $(this).find("head").text() + '</div>';
        
        
        let html = `<div class="col-sm-4 random" id="random">
                    <div class="thumbnail randomdiv3" id="border" >
                    <a href="#${tag + idx}" id="openModalBtn">

                        </a>
                    </div>
                 </div>`;

       

        let popup = `<div id="${tag + idx}" class="overlay">
