Deleting data without refreshing - PHP_PHP Tutorial

First of all, this example is modified based on the edited version of the guestbook.

We used jquery.js to implement ajax and dom deletion

First add

Add an id="t"

to the table

Write a js:

<script></div> <div>function delItem (id) {</div> <div>$.get(delete.php?id=+id,null,function (msg) {//ajax request, execute the following code after the request</div> <div>if (1==msg) {//Return 1 to indicate success</div> <div>$(#t+id).remove();//Delete the table with id txx</div> <div>} else {//Otherwise an error message will pop up</div> <div>alert(msg);</div> <div>}</div> <div> </div> <div>});</div> <div>}</div> <div></script>

Delete the link and change it to href="javascript:delItem()"

The modification to delete.php is to change the error statement to output directly.

OK done.

$rs = $query->fetch_array($q);

$error = array();

if ($rs[user_id]!=intval($_SESSION[user_id])) {// Determine whether user_id is the same

$error = You cannot delete this information, you can only delete what you posted;

}

if (!$error) {

$query->query(delete from gb_content where id=.intval($_GET[id]));//Delete statement

if ($rs[user_file]) {//Delete attachment

@unlink(uploads/.$rs[user_file]);
