Php 使用输入字段分页

我有以下分页代码

<div class="col-md-12">
  <nav aria-label="Page navigation">
    <ul class="pagination">
      <li <?php if ($products->number == 0) echo "class='active'"; ?>>
        <a <?php if ($products->number != 0): ?> href="index.php?page=0<?php echo(isset($_GET['cid']) ? '&cid=' . $_GET['cid'] : ''); ?>#prdct" <?php endif; ?>>1</a>
      </li>

      <?php if ($products->totalPages > 2) { ?>
      <?php if ($products->number > 3): ?>
      <li><a href="javascript:void(0)">...</a>
      </li>
      <?php endif; ?>
      <?php for ($i=( $products->number == 0 ? 1 : $products->number-1); $i
      < $products->number+2 && $i
        < $products->totalPages - 1; $i++) { ?>
          <li <?php if ($products->number == $i) echo "class='active'"; ?>>
            <a <?php if ($products->number != $i): ?> href="index.php?page=<?php echo $i . (isset($_GET['cid']) ? '&cid=' . $_GET['cid'] : ''); ?>#prdct" <?php endif; ?>><?php echo($i + 1); ?></a>
          </li>
          <?php } ?>
          <?php if ($products->number
          < $products->totalPages - 3): ?>
            <li><a href="javascript:void(0)">...</a>
            </li>
            <?php endif; ?>
            <?php } ?>

            <?php if ($products->totalPages > 1): ?>
            <li <?php if ($products->number == $products->totalPages) echo "class='active'"; ?>>
              <a <?php if ($products->number != $products->totalPages - 1): ?> href="index.php?page=<?php echo ($products->totalPages - 1) . (isset($_GET['cid']) ? '&cid=' . $_GET['cid'] : ''); ?>#prdct" <?php endif; ?>><?php echo $products->totalPages; ?></a>
            </li>
            <?php endif; ?>
    </ul>
  </nav>
</div>

为此使用一些JavaScript

HTML:

<input type="text" id="pageNo"/>
<button type="button" id="changePage">Change</button>

var input = document.getElementById('pageNo'),
    button = document.getElementById('changePage'),
    limit = <?php echo $products->totalPages; ?>;

button.addEventListener('click', function(){
    var page = parseInt(input.value, 10) || 1;
    location.href = 'index.php?page=' + (page <= limit ? page - 1 : limit - 1) + '<?php echo (isset($_GET['cid']) ? '&cid=' . $_GET['cid'] : ''); ?>#prdct'
})


改变

JS:

<input type="text" id="pageNo"/>
<button type="button" id="changePage">Change</button>

var input = document.getElementById('pageNo'),
    button = document.getElementById('changePage'),
    limit = <?php echo $products->totalPages; ?>;

button.addEventListener('click', function(){
    var page = parseInt(input.value, 10) || 1;
    location.href = 'index.php?page=' + (page <= limit ? page - 1 : limit - 1) + '<?php echo (isset($_GET['cid']) ? '&cid=' . $_GET['cid'] : ''); ?>#prdct'
})

var input=document.getElementById（'pageNo'），
button=document.getElementById（'changePage'），
极限=；
addEventListener（'click'，function（）{
var page=parseInt（input.value，10）| 1；
location.href='index.php？page='+（页面使用下拉字段我的分页页码也显示在地址栏上。我只需使用任何页码i重命名？page=2want@PranavCBalan需要带有输入字段的按钮输入数字时显示默认页面，然后单击更改按钮
