Ajax方法代碼及前臺ajax分頁

$.ajax({
        type : "post",
        dataType : 'json',
        url : "${pageContext.request.contextPath}/subjectInformation/page.action",
        data : {
                參數名1 : 參數值1,
                參數名2: 參數名2
                },
        success : function(res) {
                //回掉函數
                }
        });

分頁代碼：

<script type="text/javascript">
    $(function() {
        //頁面一加載，調用pagelist訪問後臺，請求分頁數據
        pagelist()
    });

    function pagelist(pageNumber, totalpage) {
        //若當前頁大於總頁數，不請求後臺
        if (pageNumber > totalpage) {
            alert("親，這是最後一頁了，不要再探索我了" + '!');
            return false;
        }

        //若當前頁大於第一頁，不請求後臺
        if (pageNumber < 1) {
            alert("親，這是第一頁哦，不要再玩耍我了" + '!');
            return false;
        }
        //每次請求清空當前頁面的數據
        $(".thead").empty();
