data.forEach((i,index)=>{ i.operatedate=i.operatedate.substring(0,10) let iconHtml = ''; if(i.operatedate === '2023-05-24'){ iconHtml = '<i class="glyphicon glyphicon-star-empty"></i>'; } $(".bottombingo").append(` <div class="bingodiv" style="margin-bottom:10px;" onclick="verxxggfb_id('\${i.id}')"> <div style="font-size:14px;font-weight:bolder;white-space:nowrap;overflow:hidden;">\${i.title}&nbsp;\${iconHtml}</div> <div style="font-size:12px;color:#3e3e3e;">\${i.operatedate}</div> </div>`) if(index == data.length-1){ //内部内容总高度 var height1 = $(".bottombingo").height(); var height2 = $(".bottombingo").parents('.card-table').height(); if(height1>height2){ //超出原本高度去进行上下走马灯 // setInterval(timerxxts,3000); var timer; // 定时器变量 // 启动定时器 timer = setInterval(timerxxts, 3000); // 鼠标进入 .bottombingo 时清除定时器 $(".bottombingo").on("mouseenter", function() { clearInterval(timer); }); // 鼠标离开 .bottombingo 时重新启动定时器 $(".bottombingo").on("mouseleave", function() { timer = setInterval(timerxxts, 3000); }); } } })修改这段代码使i.operatedate等于近三天的日期后iconHtml才有值

可以将第5行的日期判断条件改为：

if (new Date(i.operatedate) >= new Date(new Date().getTime() - 3 * 24 * 60 * 60 * 1000)) {
    iconHtml = '<i class="glyphicon glyphicon-star-empty"></i>';
}

这样就可以判断i.operatedate是否在三天内了。具体代码如下：

data.forEach((i, index) => {
    i.operatedate = i.operatedate.substring(0, 10);
    let iconHtml = '';
    if (new Date(i.operatedate) >= new Date(new Date().getTime() - 3 * 24 * 60 * 60 * 1000)) {
        iconHtml = '<i class="glyphicon glyphicon-star-empty"></i>';
    }
    $(".bottombingo").append(`
        <div class="bingodiv" style="margin-bottom:10px;" onclick="verxxggfb_id('${i.id}')">
            <div style="font-size:14px;font-weight:bolder;white-space:nowrap;overflow:hidden;">${i.title}&nbsp;${iconHtml}</div>
            <div style="font-size:12px;color:#3e3e3e;">${i.operatedate}</div>
        </div>`)
    if (index == data.length - 1) {
        //内部内容总高度
        var height1 = $(".bottombingo").height();
        var height2 = $(".bottombingo").parents('.card-table').height();
        if (height1 > height2) {
            //超出原本高度去进行上下走马灯 //				          setInterval(timerxxts,3000);
            var timer; // 定时器变量
            // 启动定时器
            timer = setInterval(timerxxts, 3000);
            // 鼠标进入 .bottombingo 时清除定时器
            $(".bottombingo").on("mouseenter", function() {
                clearInterval(timer);
            });
            // 鼠标离开 .bottombingo 时重新启动定时器
            $(".bottombingo").on("mouseleave", function() {
                timer = setInterval(timerxxts, 3000);
            });
        }
    }
});
