【中文标题】在模态中打开动态图像(弹出)【英文标题】:Open a dynamic image in modal (pop up) 【发布时间】:2018-06-05 08:20:00 【问题描述】:我正在从 mysql 列表中检索图像源的路径。我想在 Bootstrap 模式中打开这个图像(预览),但它没有得到正确的图像。
这是我的 php 代码:
$sql="SELECT * FROM `dirf1` WHERE `root` = '$root' AND `pId` = '$pid' ORDER BY fileType";
$result_set=mysqli_query($GLOBALS["___mysqli_ston"], $sql);
while($row=mysqli_fetch_array($result_set))
<td><a href="f/'.$row['fileName'].'"><?php echo $link; ?><i style="font-size:22px; color:#FF9900;"></i>   <?php echo $row['fileName'] ?></a></td>
这是我的引导模式代码:
<!-- Modal image preview -->
<div class="modal fade" id="myModal" role="dialog">
<div class="modal-dialog">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title" align="center">Image</h4>
</div>
<div class="modal-body">
<img src="f/<?php echo $showName; ?>" >
</div>
<div class="modal-footer">
</div>
</div>
</div>
</div> <!-- modal image preview end -->
如何在 Bootstrap modal 中打开动态图像?
【问题讨论】:
你能帮忙吗? ***.com/users/1213708/nigel-ren 如果它没有得到正确的图像名称,那么任何前端帮助都将无济于事。在这种情况下,您的 SQL 或 PHP 有问题。 它在表中回显正确的名称,但在模态中仅显示第一个结果。查询工作正常。你能检查一下这段代码吗? @雪猴 所以当用户从给定的 td 元素中选择它时,您正在寻找一个显示图像的模式?在那种情况下,您弹出模式的 javascript 是什么? 我正在使用默认的引导模式,它不需要任何外部 javascript 代码。 @雪猴 【参考方案1】:正如我在笔记中反复说过的,您不需要任何其他 javascript 来弹出模态框。你是绝对正确的。但是,如果您希望将 DYNAMIC 内容插入到模态中,那么我是对的,您确实需要某种外部控制。如果您点击引导文档的链接,您会看到类似于以下内容的内容:
/****
* When the modal is displayed, I want to get my dynamic content.
* In this case, the dynamic content is a data-whatever attribute
* and the actual text content of the clicked LI element.
*
* I will take that content, and use it to populate my modal
* dynamically. In this way, I have a single modal popup with content
* from any number of sources. The only requirements are that the
* triggering element have a data-whatever attribute and some
* sort of text content.
* All of this is happening when my modal is triggering its show
* event, so it will all happen just before the modal is displayed.
****/
$('#myModal').on('show.bs.modal', function (event)
// Element that triggered the modal
var liEl = $(event.relatedTarget);
// Extract info from data-* attributes, and from the element itself.
var recipient = liEl.data('whatever');
var textContent = liEl.text();
// If necessary, you could initiate an AJAX request here
// (and then do the updating in a callback).
// Update the modal's content. We'll use jQuery here, but you could
// use a data binding library or other methods instead.
var modal = $(this);
// Update the dynamic portions of the modal dialog.
modal.find('.modal-title').text('New message to ' + recipient);
modal.find('.modal-body textarea[name="message-body"]').text(textContent);
);

请注意,对话框本身是由 Bootstrap 处理的。我与它无关。我不理会那件作品,因为它工作正常。但是我可以并且应该挂钩到 Bootstrap API 并监听模态的show.bs.modal
事件——此时,我想返回触发元素,获取它的内容,并填充我的单个模态。这是动态位。
回答你的问题,是的。是的,我在引导程序方面有丰富的经验。有吗?
