我正在尝试确保用户想要从数据库中删除条目。我宁愿暂停初始函数中的操作而不是尝试在删除函数中执行它,因为这更有意义。无论如何,该网站不断跳过确认对话框,只是继续删除该条目。我不确定它是否只是一个语法错误,但我无法弄清楚为什么我的jQuery不会跳闸。
<script type="text/javascript" src="jquery-1.10.2.min.js" ></script>
<script>
$(document).ready(function(){
('a.confirm').click( function( event){
event.preventDefault();
var url = $(this).attr('href') ;
var confirm_box = confirm( "Are you sure you want to delete this player?" );
if( confirm_box ){
window.location = url;
}
} );
});
</script>
<?php
function roster_table()
{
try{
if( isset( $_SESSION['session_id'] ) )
{
$db = honneyconnect( ) ; // db connection established
if( mysqli_connect_error() )
{
throw new Exception( "Could not connect to the database") ;
}
$query = 'select * from roster' ;
$players = $db->query( $query ) ;
if( !$players )
{
throw new Exception ( "Query returned zero results" ) ;
}
else
{
$number_of_players = $players->num_rows ;
echo "<div id='player_table'>
<table><th>Hells Canyon Honeys Active Skaters</th>" ;
for( $i = 0; $i < $number_of_players; $i++ )
{
$row = $players->fetch_row() ;
echo "<tr><td>".$row[0]."</td><td>".$row[1]."</td><td>".$row[2]."</td>
<td><a href='http://localhost/honeysproject/editplayer.php?player_id=".$row[0]."'>Edit</a></td>
<td><a class='confirm' href='http://localhost/honeysproject/deleteplayer.php?player_id=".$row[0]."'>Delete</a></td></tr>" ;
}
echo "<tr><td><a href='http://localhost/honeysproject/playerinfoentry.php'>Add Player</a></td></tr></table></div>" ;
}
}
else
{
throw new Exception( "You are no longer authorized to view this document. Please re-authenticate!<br>" ) ;
session_destroy( ) ;
}
}
catch( Exception $error )
{
echo $error ;

更改('a.confirm').click( function( event){
到$('a.confirm').click( function( event){

通过$
选择元素时,您错过了(a.confirm).click(...)
。
修复如下:
$('a.confirm').click(function(event){
//...
});
此外,您只需使用以下内容即可简化整个脚本:
$(document).ready(function(){
$('a.confirm').click(function(event){
return confirm( "Are you sure you want to delete this player?" );
});
});
根据返回值(true
或false
),重定向将自动处理。

你在选择器('a.confirm')中缺少$。 关于确认对话this可能应该帮助你
