success: function(msg){
    if(msg==1){
    $('#delete').html("success"); //if success message appear only i have to remove particular row
    })

<table border="1">
<tr>
    <th>Title</th>
    <th>Public Id</th>
    <th>Pass</th>
    <th></th>
</tr>
<?php
$select = $db->select ()
    ->from ( 'test', '*' )
    ->where ( 'user_id = ?', 1 )
    ->where ( 'test.created > DATE_SUB(CURDATE(), INTERVAL 7 DAY)' );
$tourDetails = $db->fetchAll ( $select );
$i = 0;
foreach ( $tourDetails as $row1 ) {
    $i ++;
    $title = $row1 ['title'];
    $PublicId = $row1 ['public_id'];
    if (($i % 2) == 0 ) {
        $rowResponse =  prepareRow ( true, $title, $PublicId);
        echo $rowResponse;
    } else {
        $rowResponse = prepareRow ( false, $title, $PublicId);
        echo $rowResponse;
    }
}
function prepareRow($flag, $title, $PublicId) {
$rowResponse = "";
if ($flag) {
    $rowResponse .= '<tr class="even">';
} else {
    $rowResponse .= '<tr class="odd" >';
}
    $rowResponse .= '   
    <td> ' . $title . ' </td>
    <td> ' . $publicId . ' </td>
    <td><p><a onclick=openDialog("'. $PublicId .'","delete") href="#" id="dialog_link"> 
    Delete </a></p>
    </td>';
return $rowResponse;
?>

2 个解决方案

#1

You can use jQuery's nth-child selector.

您可以使用jQuery的第n个子选择器。

$("table#mytableid tr:nth-child(2)").remove();

This will remove the second row, for example. Make sure your table has an ID or a class so that you select it more easily (not accidentally removing 2nd row of EVERY table on the page, in case you have more)...

例如，这将删除第二行。确保您的表具有ID或类，以便您更容易地选择它(不要意外地删除页面上每个表的第2行，以防您有更多的表)……

From what I see in your code, you could select the parent tr element from your onclick event and then either send it to the function as a new parameter (which you would remove it the ajax returns success) or remove it right away... or whatever you want.

从您的代码中可以看到，您可以从onclick事件中选择父tr元素，然后将它作为一个新的参数发送给函数(您将删除它，ajax返回success)，或者立即删除它……或任何你想要的。

$('#myTableRow').remove(); 

 This works fine if your row has an id, such as:
<tr id="myTableRow"><td>blah</td></tr>
