<body>

<ul class="pager">
    <!--    <li class="pre">上一页</li>-->
    <!--    <li class="btn">1</li>-->

<script src="http://libs.baidu.com/jquery/2.0.0/jquery.min.js"></script>
<script type="text/javascript">
    var total = 10

    checkPage(1)

    function checkPage(curpage) {
        curpage = parseInt(curpage)

        var startPage = curpage - 2;
        var endPage = curpage + 2;
        if (curpage < 5 && total > 5) {
            endPage = 5
        }

        if (startPage < 1) {
            startPage = 1
        }

        if (endPage >= total) {
            endPage = total
        }


        let str = '';

        if (curpage > 1) {
            str += '<li class="pre" onclick="checkPage(' + (curpage - 1) + ')">上一页</li>'
        } else {
            str += '<li class="pre" style="background-color: beige;">上一页</li>'
        }

        for (let i = startPage; i <= endPage; i++) {
            if (curpage === i) {
                str += '<li class="btn" style="background-color: burlywood">' + i + '</li>'
            } else {
                str += '<li class="btn" onclick="checkPage(' + i + ')">' + i + '</li>'
            }
        }

        if (curpage < total) {
            str += '<li class="next" onclick="checkPage(' + (curpage + 1) + ')">下一页</li>'
        } else {

        }

        $(".pager").html(str)
    }
