Question

我有这部分代码用于我的分页，向后显示记录。它运作良好，但只在24页测试。必须进行调整以支持更多（100 +）。

寻呼机看起来像

window.onload = function () {


    document.querySelector(".button.wc-backward").onclick = function() {

        var URLstring = document.referrer;  // works fine

        window.location.href = URLstring;  // ref unchanged

        setTimeout(function () {
            window.location.href = URLstring; },100);  // same result

        return false;
    }
}

我的代码：

24 23 22 21 20 (current 19) 18 17 16 15 14 ... 2 1

24 23 ... 14 13 12 11 10 (current 9) 8 7 6 5 4 ... 2 1

24 23 ...  11 10 9 8 7 (current 6) 5 4 3 2 1

有什么建议吗？非常感谢你提前！

Answer 1

我不确定但是尝试使用此循环

for ($counter = $lpm1 - $adjacents; $counter - $adjacents > 2; $counter--)

如果它返回错误的数字但反转的顺序是正确的，那么将结果发布在这个答案中我将尝试思考如何解决它
