	}
}

　　4、jquery代码

var pagination = $("#pagination-container");
var now_page = 1;
var total_page = 30;
createPagination(pagination, now_page, total_page);
function createPagination(pagination, now_page, total_page) {
    initPagination();
    addPaginationEvent();
    function initPagination() {
        pagination.empty();
        var lineOne = $("<div class = ‘div‘>" +
            "<span>当前页：</span>" +
            "<span class=‘now-page num‘>" + now_page + "</span>" +
            "<span>/</span>" +
            "<span class=‘num total-page‘>" + total_page + "</span>" +
            "<span>跳转到</span>" +

            if (now_page > 1) {
                now_page--;
                fillNumberPage(now_page);
            }
        })
        nextPageBtn.on("click", function() {
            if (now_page < total_page) {
                now_page++;
                fillNumberPage(now_page);
            }

    }

    function fillNumberPage(page) {
        pagination.find(".center").empty();
        pagination.find(".now-page").text(page);
        pagination.find(".jump-top-page").val(page);
        var start;
        var end;
        var p = page;
        if (total_page <= 7) {
            start = 1;
            end = total_page;
        } 
        else {
            if (page <= 4) {
                start = 1;
                end = 7;
            } else if (page > 4 && page < total_page - 4) {
                start = page - 3;
                end = page + 3;
            } else {
                start = total_page - 7;
                end = total_page;
            }
        }
        for (var i = start; i <= end; i++) {
            var pageCenter = $("<a href=http://www.mamicode.com/‘#‘ class=‘page‘ data-page = ‘" + i + "‘>" + i + "</a>");
            if (i == p) {
                pageCenter.addClass("choose");
            }
            pagination.find(".center").append(pageCenter);
        }
    }
}

　　5、总结

将父节点，当前页，总页数传给创建函数就可以生成分页。

（还没加跳页的功能）
