我正在尝试获取pdf / image的文件名，以将其显示在本地表中。当我得到文件名时，我希望它在<a>标记中，然后在其中隐藏到弹出弹出div的href为<embed>。问题是src的值不会更改，并且所有文件名都相同（所有文件名都为
这是我的代码：
while($row=mysql_fetch_assoc($search)){
?>
<div aria-hidden="true" role="dialog" tabindex="-1" id="login-forms" class="modal leread-modal fade in">
<div class="modal-dialog">
<div class="modal-header">
<button aria-label="Close" data-dismiss="modal" class="close" type="button"><span aria-hidden="true">X</span>
</button>
</div>
<div class="modal-body" name="place">
<embed src="stuUploads/<?php echo $row['upload'];?>" id="up" type="application/pdf" width="600px" height="500px" />
</div>
<div class="modal-footer footer-box">
</div>
</div>
</div>
我使用jQuery更改了<embed>标记中src属性的值，但结果是文件的姓（数据库的最后一行）
这是代码
<script>
$(document).ready(function(){
$('#up').attr('src',"stuUploads/<?php echo $row['upload'];?>");
});
</script>
这是整个循环
if(mysql_num_rows($search)>0){ ?>

如果有另一种方法可以在同一页面中弹出文件，请提出建议。 感谢任何帮助。

使用class代替id。Id是唯一的
<embed src="stuUploads/<?php echo $row['upload'];?>" class="up" type="application/pdf" width="600px" height="500px" />
并将相应的js元素id更改为class
$(document).ready(function(){
$('.up').attr('src',"stuUploads/<?php echo $row['upload'];?>");
});
答案 1 :(得分：0)
使用class属性代替id。一个ID应该是唯一的（这意味着只能使用一次）。
由于您要遍历多维数组$row[]，因此只能在while循环内访问$search。
答案 2 :(得分：0)
在循环中使用<a href="#login-forms" data-toggle="modal" data-target="#login-forms" data-url="stuUploads/<?php echo $row['upload'];?>">XXX</a>
如果使用引导程序，请添加
$('#login-forms').on('shown.bs.modal', function (e) {
var $invoker = $(e.relatedTarget);
$("#up").attr("src", $invoker.data("url"));
});
答案 3 :(得分：0)
请记住，$row['upload']只是一个值，每次通过while循环都会改变。当您将up从ID更改为类时，您的脚本实际上每次在页面上运行的每个src重新定义了up。更好的解决方案是定义一个更好的id，因为您只打算更改单个embed。可以使用$row['upload']作为您的ID吗？
<embed src="stuUploads/<?php echo $row['upload'];?>" id="<?php echo $row['upload'];?>" type="application/pdf" width="600px" height="500px" />
然后您可以将脚本更改为：
<script>
$(document).ready(function(){
$('#'+<?php echo $row['upload'];?>).attr('src',"stuUploads/<?php echo $row['upload'];?>");
});
</script>
