[原創]jquery+css3打造一款ajax分頁插件

時間 2019-11-12

標籤原創 jquery+css3 jquery css 打造一款 ajax 分頁插件欄目 JQuery 简体版

原文原文鏈接

最近公司的項目將好多分頁改爲了ajax的前臺分頁
之前寫的分頁插件就很差用了，遂重寫一個javascript

支持IE6+，但沒有動畫效果
若是沒有硬需求，我的認爲不必多寫js讓動畫在這些瀏覽器中實現
css3的動畫原本就是幫咱們取代js中這部分動畫代碼的
使js更純粹地去實現邏輯css

效果圖以下：html

調用代碼以下：java

包括經常使用的加載失敗重試，參數可配置是否能手動輸入頁碼，設置按鈕數目，能夠調用多個page等等，調用代碼很簡便jquery

<script type="text/javascript">
    var kpage;

    $(function () {
        tocount();
    });

    function tocount() {
        //初始化
        $.ajax({ url: "/Service/DBCount", type: "post", success: function (e) {
            kpage = $("#divPage").page({ dataCount: e, pageChange: topage });
        }
        });
    }

    function topage(i, s) {
        //數據查詢
        $("#divInfo").html("加載中...");
        $.ajax({ url: "/Service/List", type: "post", data: { PageSize: s, PageIndex: i }, success: function (r) {
            $("#tList").html(r);
            $("#divInfo").html("");
        }, error: function () {
            $("#divInfo").html("加載失敗...<a href='javascript:reload();'>重試</href>");
        }
        });
    }

    function reload() {
        kpage.reload();
    }

</script>
