Question

我有一个代码，用于显示数据库列表和一个loadmore按钮。显示所有记录列表后，单击loadmore按钮以显示空白位置。

显示所有记录后如何隐藏loadmore按钮？

index.php文件：

<?php $chinp=$_GET['schinp'];?>
<div  id="schts"></div>
<button id="btnsch">load more</button>

<script>
$(document).ready(function() {
    var chinp="<?php echo $chinp;?>";
  var srchco = 1;
  var offsrch = 0;
  $("#btnsch").click(function() {
    $.ajax({
        method: "POST",
       url: "search.php",
        data: { srchcoun: srchco, offsrch: offsrch ,chinp:chinp}
      })
      .done(function(msg) {
        $("#schts").append(msg);
      });
    offsrch = offsrch + srchco;
  });

  $("button").trigger("click");
});
</script>

search.php：

$srchcoun=$_POST['srchcoun'];
$offsrch=$_POST['offsrch'];
$chinp=$_POST['chinp'];
$schql="SELECT id, name, lastname FROM t_users WHERE name LIKE '$chinp' ORDER BY name ASC limit $offsrch, $srchcoun";
$rsch=mysqli_query($conn,$schql);

while ($rch=mysqli_fetch_assoc($rsch)){
     $scid=$rch['id'];$snm=$rch['name'];$slnm=$rch['lastname'];?>

<div class="alsu">
<img class="sask" src="pic/<?php echo $scid;?>.png" alt="">
<span class="snm">Name : <?php echo $snm." ".$slnm;?></span>
</div>
<?php }?>
</div>

谢谢。

以下是根据您的代码隐藏加载更多按钮的代码。

将此代码替换为您的第一个文件。

import matplotlib.pyplot as plt
y = range(0,21,1)
x = range(0,21,1)
y_err = [0.5]*21

x_low = [0.7]*21
x_upper = [1.4]*21
x_err = [x_low, x_upper]

fig, ax = plt.subplots()
idx = range(0, 16, 7)
for start, stop in zip(idx[:-1], idx[1:]):
    ax.errorbar(x[start:stop], y[start:stop], y_err[start:stop], \
                [ i[start:stop] for i in x_err])

现在将此代码添加到您的搜索文件中。

<script type="text/javascript">
$(document).ready(function() {
  var chinp="<?php echo $chinp;?>";
  var srchco = 2;
  var offsrch = 0;
  var page_num = 0;

  $("#btnsch").click(function() {
    $.ajax({
      method: "POST",
      url: "search.php",
      data: { srchcoun: srchco, offsrch: offsrch ,chinp:chinp, page_num : page_num}
      })
      .done(function(msg) {
        if(msg == 'noMoreData'){
          $("#btnsch").hide();
        } else {
          $("#schts").append(msg);
        }
      });
      page_num = page_num + 1;
    offsrch = offsrch + srchco;
  });

  $("#btnsch").trigger("click");
});
</script>

尝试一下，让我知道是否有任何问题。

从数据库加载整个数据后，只需在ajax部分使用$('#myButtonId').hide();。
