我制作了一个表格，用于向用户显示有关某些演示文稿的信息。我使用了 ajax，因为它应该被加载到一个 div 容器中，而不是在每次更改年份时都重新加载。
这是我的 JavaScript：
$("#select_coffee_talk_year").button().click(function() {
var form = $('#coffee_talk_year');
var data = form.serialize();
$.ajax({
url: 'include/scripts/select_event.php',
type: 'POST',
data: data,
dataType: 'html',
success: function (select) {
$("#coffee_talk").html(select);
$("#coffee_talk").fadeIn();
}
});
return false;
});
这是我的 select_event.php：
if ('POST' == $_SERVER['REQUEST_METHOD']) {
/*******************************/
/** Erzaehlcafe auswählen
/*******************************/
if (isset($_POST['coffee_talk_year_submit'])) {
$getID = array();
$getDate = array();
$getTheme = array();
$getContributer = array();
$getBegin = array();
$getPlace = array();
$getEntrance = array();
$getFlyer = array();
$sql = "SELECT
ID,
Date,
Theme,
Contributer,
Begin,
Place,
Entrance,
Flyer
FROM
Coffee_talk
WHERE
YEAR(Date) = '".mysqli_real_escape_string($db, $_POST['year_coffee_talk'])."'
ORDER BY
Date ASC
";
if (!$result = $db->query($sql)) {
return $db->error;
}
while ($row = $result->fetch_assoc()) {
$getID[$i] = $row['ID'];
$getDate[$i] = $row['Date'];
$getTheme[$i] = $row['Theme'];
$getContributer[$i] = $row['Contributer'];
$getBegin[$i] = $row['Begin'];
$getPlace[$i] = $row['Place'];
$getEntrance[$i] = $row['Entrance'];
$getFlyer[$i] = $row['Flyer'];
$i++;
}
$result->close();
/****************************/
/** Output der Tabelle
/****************************/
if ($getID[0] == '') {
echo 'Kein Eintrag vorhanden';
} else {
//Kopf
echo '<table id="table">
<thead>
<tr id="table_head">
<th>Nr.</th>
<th>Datum</th>
<th>Thema</th>
<th>Referent</th>
<th>Begin</th>
<th>Ort</th>
<th>Eintritt</th>
<th>Flyer</th>
<th>Bearbeiten</th>
</tr>
</thead>
<tbody>';
//Mittelteil
$j = 0;
for($i = 0; $i < count($getID); $i++) {
$j = $i + 1;
echo '<tr>
<td class="center">'.$j.'</td>
<td class="center">'.$getDate[$i].'</td>
<td class="center">'.$getTheme[$i].'</td>
<td class="center">'.$getContributer[$i].'</td>
<td class="center">'.$getBegin[$i].'</td>
<td class="center">'.$getPlace[$i].'</td>
<td class="center">'.$getEntrance[$i].'</td>';
if ($getFlyer[$i] == '') {
//Kein Bild vorhanden
echo '<td class="center">Kein Bild vorhanden</td>';
} else echo '<td class="center">'.$getFlyer[$i].'</td>';
echo '<td class="center">
<table id="icons">
<tr>
<td>
<a href="#" data-event-id="'.$getID[$i].'" data-table="Coffee_talk" class="edit_event">
<img src="images/edit.png" />
</a>
</td>
<td>
<a href="#" data-event-id="'.$getID[$i].'" data-table="Coffee_talk" class="delete_event">
<img src="images/delete.png" />
</a>
</td>
</tr>
</table>
</td>
</tr>';
}
//Ende
echo '</tbody>
</table>';
}
}
}
如您所见，我的输出是一张桌子。我正在使用链接进行编辑和删除功能：
<a href="#" data-event-id="'.$getID[$i].'" data-table="Coffee_talk" class="edit_event">
<img src="images/edit.png" />
</a>
和
<a href="#" data-event-id="'.$getID[$i].'" data-table="Coffee_talk" class="delete_event">
<img src="images/delete.png" />
</a>
这是我的带有占位符 div 的 html：
<div>
<p class="bold underline headline">Bereits eingetragen:</p>
<form id="coffee_talk_year" action="include/scripts/select_event.php" method="post" accept-charset="utf-8">
<select name="year_coffee_talk" id="year_coffee_talk">
<option value="none" class="bold italic">Jahr</option>
<?php
for($i=2008; $i<=$year; $i++){
if ($i == $year) {
echo "<option value=\"".$i."\" selected=\"$i\">".$i."</option>\n";
} else echo "<option value=\"".$i."\">".$i."</option>\n";
}
?>
</select>
<button id="select_coffee_talk_year">anzeigen</button>
<input type="hidden" name="coffee_talk_year_submit" value="true" />
</form>
<br />
<div id="coffee_talk"></div>
<br />
<button id="add_coffee_talk">hinzufügen</button>
</div>
现在我想用这个 JavaScript 来做一个删除和编辑功能：
$(".delete_event").click(function() {
alert('hallo');
currentUserID = $(this).data("event-id");
currentTable = $(this).data("table");
$( "#dialog_delete_event" ).dialog( "open" );
});
$( '#dialog_delete_event' ).dialog({
autoOpen: false,
resizable: false,
height: 170,
modal: true,
buttons: {
'Ja': function() {
document.location = "index.php?section=event_delete&id=" + currentUserID +"&table=" + currentTable;
$( this ).dialog( 'close' );
},
'Nein': function() {
$( this ).dialog( 'close' );
}
}
});
我的问题是 click_function （在链接中定义）不起作用。我发现ajax表单响应没有写入html代码。打赌这是问题所在。我该怎么做才能给链接一个有效的点击功能？
