我有一个php表，我希望能够删除我选择的行，但我不知道如何进行。这是我删除的javascript：
// When a delete button is pressed in one of the rows
function deleteCurrentRow(whatrow)
{
//deletes the approriate row according to what button was pressed
if (hasLoaded) {
var delRow = whatrow.parentNode.parentNode;
deleteRows(delRow);//sends the row for deletion to the function to be deleted
}
}
function deleteRows(rowforDeletion)
{
if (hasLoaded) {
var rowPos = rowforDeletion.sectionRowIndex;//postion of the row for deletion
rowforDeletion.parentNode.deleteRow(rowPos);//deletes row
increment = increment -1;
}
}
这是我的php表：
<table border="1" cellspacing="5" id="tblmarkscheme" style="float: center;">
<thead>
<tr>
<th colspan="5">Template</th>
</tr>
<tr>
<th>Mark</th><th>Criteria</th><th>Delete</th>
</tr>
</thead>
<tbody>
<?php
$query = "SELECT maxMark, criteria FROM mark ";
$result = mysql_query($query);
while ($row = mysql_fetch_array($result))
{
echo "<tr>";
echo "<td>" ."<input type = text name = text size = 1 id = mark value = ". $row['maxMark'].">" ."</td>";
echo "<td>"."<textarea>".$row['criteria']. "</textarea>"."</td>";
echo "<td>"."<input type = button value = Delete onclick = deleteCurrentRow(this);/>"."</td>";
echo "</tr>";
}
?>
</tbody><!--elements added onload and when button pressed -->
</table>
我想通过按下按钮来删除表中的各个行
这里有一个例子；如果你点击一个按钮，它的行就会被删除：
<!DOCTYPE HTML>
<html>
<head>
<script type="text/javascript">
var p = {
deleteRow: function(row) {
document.getElementById("mytable").deleteRow(row.rowIndex);
}
};
</script>
</head>
<body>
<table id="mytable">
<tr>
<td><input type="button" value="row1" onclick="p.deleteRow(this)"/></td>
</tr>
<tr>
<td><input type="button" value="row2" onclick="p.deleteRow(this)"/></td>
</tr>
</table>
</body>
</html>
实际上这是一个html表。
您将需要使用javascript来删除行。

<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script>
function del(id)
{
var info = 'id=' + id;
if(confirm("Are you sure you want to delete this Record?")){
var html = $.ajax({
type: "GET",
url: "deletCourse.php",
data: info,
async: false ,
success: function() {
window.location.reload(true);}
}).responseText;
}
}
</script>
<?php
$link=mysql_connect("localhost","root","") or die(mysql_error());
mysql_select_db("cart");
$sql=mysql_query("SELECT * FROM `details`");
echo "<table>";
echo "<tr><th>Name</th><th>NO of Items</th></tr>";
while($row = mysql_fetch_assoc($sql)){
echo '<tr class="record">';
echo "<td>" . $row['name'] . "</td>";
echo "<td>" . $row['num'] . "</td>";
echo '<td><div align="center"><a href="#" id="' . $row['id'] . '" onclick="del('.$row['id'].')">delete</a></div></td>';
echo '</tr>';
}
echo "</table>";
mysql_close($link);
?>``
