所以我用来自controller 和model 的静态数据创建了div。现在，当我点击ADD 按钮时，应该将一个新项目添加到列表中，并且应该自动将div 显示到页面。希望我很清楚:)

请指导我如何实现它？谢谢

它之前应该可以工作，但我猜你改变了 html ，好吧试试这个

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<script>
    var i=y=0;
    var newarr = new Array();
    var divContent = '';

@foreach (var job in Model)
{

divContent = '<div class="panel panel-default" id="panel2"><div class="panel-heading-new"><h4 class="panel-title" id="newpanel1"><a data-toggle="collapse" data-target="#collapseTwo" href="#collapseTwo">';
divContent += '@Html.DisplayFor(modelItem => job.Header, new { job.Id })';
divContent += '</a></h4></div><div id="collapseTwo" class="panel-collapse collapse in"><div class="panel-body"><p class="lead justified">';
divContent += 'Qualifications and Skills:';
divContent += '</p><ul class="fa-ul">';
divContent += '<li><i class="fa-li fa fa-hand-o-right pad-icon"></i><span class="lead justified">@Html.DisplayFor(modelItem => job.Content, new { job.Id })</span></li>';
divContent += '</ul><br /></div></div></div>';
newarr[i] = $(divContent);
i = i +1;

}
$(document).ready(function(){
    $("a#add").click(function(){
        if (y<i) {
            var content = newarr[y];
            $('#maincontainer').append(content);
            y++;
        } else {
            alert('No other Job!');
        }
        return false;
    });
});
</script>



<a href="#" id="add">ADD</a>

    <div class="container">
    <div class="col-lg-12" id="maincontainer">


     </div>
</div>
