实习效果：点击红色的叉进行删除时，整个页面地址不变，实现局部刷新

jsp页面中：

<pre name="code" class="java"><c:forEach items="${files}" var="item" varStatus="i">
    <input type="hidden" id="fileId" value="${item.id}" />
    <a style="display:inline-block;width: 250px;" href="download.htm?fileId=${item.id}&&assetId=${item.assetId}">${item.fileName}</a>
    <a style="color: red;background-color:ghostwhite;text-align: center;display:inline-block;width: 25px;"  id="delete${i.count}">X</a><br/><br/>
    <script>
        $(document).ready(function() {
            $("#delete${i.count}").click(function () {
                $.ajax({
                    type:"POST",url:"filedelete.htm",data: {fileId:$("#fileId").val()},success:function () {
                        window.location.reload();
                    }
                })
            })
        })
    </script>
</c:forEach>

@RequestMapping("filedelete")
public String fileDelete(Long fileId) {
    bizAssetReviewService.deleteFile(fileId);
        return "biz/asset/assetedit";//回到原来所在的jsp页面
}
