Question

我创建了一个删除按钮，使用jquery和ajax从我的数据库中删除一行。当我点击按钮时出现错误：Uncaught ReferenceError: element is not defined.

然后高亮显示var del_id = element.attr("id");

 <a href="#" id="14" class="delbutton"><i class ="fa fa-trash"></i></a>


<script type="text/javascript">
    $(function() {

    $(".delbutton").click(function(){
    var del_id = element.attr("id");
    var info = 'id=' + del_id;
    if(confirm("Sure you want to delete this?"))
    {
    $.ajax({
    type: "POST",
    url: "feed/deletepost",
    data: info,
    success: function(){
    }
    });
    $(this).parents(".record").animate({ backgroundColor: "#fbc7c7" }, "fast")
    .animate({ opacity: "hide" }, "slow");
    }
    return false;
    });
    });
</script>

关于可能导致这种情况的任何想法？

这是因为element未定义：D尝试这样做：

$(".delbutton").click(function(){
  var del_id = $(this).attr("id");....
