我从数据库加载了以下页面(processor.php)表。当我点击链接时,它会连接到solve.php,以便通过GET和特定ID下载或查看。 当我点击"下载",没有问题,图片下载,同时留在processor.php
在Ajax功能中,我已经提到"?"标记不知道如何处理数据。请完成它?
$(document).ready( function() {
$("#?????????").click(function(e) {
e.preventDefault();
$.ajax({
url: "solve.php",
type: "GET",
data: ?????,
success: function(data){ //function to be called if request succeeds
$("#preview").html(data);
}
});
});
});
CREATE TABLE Upload(
Id INT NOT NULL AUTO_INCREMENT,
Name VARCHAR(30) NOT NULL,
Type VARCHAR(30) NOT NULL,
SizeMB DECIMAL(9,2) NOT NULL,
Content LONGBLOB NOT NULL,
PRIMARY KEY(Id)
);
processor.php
$query = "SELECT Id,Name,Type,SizeMB FROM Upload"; // Good practice. Do not process much data here. leave Content field
$result = mysqli_query ( $con, $query) or die ("Couldn't execute SELECT query: ". mysqli_error($con));
$nrows = mysqli_num_rows($result);
echo '<table>
<tr>
<td>Id</td>
<td>Name</td>
<td>Type</td>
<td>Size (MB)</td>
</tr>';
$selfpg = $_SERVER['PHP_SELF'];
while( $row = mysqli_fetch_assoc($result) ){
extract($row);
echo "<tr>
<td>$Id</td>
<td>$Name</td>
<td>$Type</td>
<td>$SizeMB</td>
<td> <a href='solve.php?id=$Id'> Download </a> </td>
<td> <a href='solve.php?id=$Id&view=preview'> View </a> </td>
</tr>";
}
echo '</table>';

在你的html中添加一个类到链接
<a class="image-view" href='solve.php?id=$Id&view=preview'>
在javascript中,找到包含此类的所有元素,并获取所单击的属性的href属性。
$(".image-view").click(function(e) {
e.preventDefault();
var url = $(this).attr('href'); // Get href attribute of current element
$.ajax({
url: url, // Use url with arguments
type: "GET",
success: function(data){ //function to be called if request succeeds
$("#preview").html(data); // It should be html here
}
});
});
