林：https://github.com/isocra/TableDnD/blob/master/index.html錶行下降，使用這個插件獲取ID和序列
如果我拖&下降一排，我得到警報被丟棄的行ID，它的工作原理。
我怎樣才能得到行序列？我想用這個，用ajax更新圖像序列。
$("#table-2").tableDnD({
onDrop: function(table, row) {
var rows = table.tBodies[0].rows;
var debugStr = "Row dropped was ID: "+row.id+"";
alert(debugStr);
}
});
我從我的網站複製表源代碼soruce，表由php生成。
<table class="table table-hover table-bordered list" id="table-2">

更新：
如果我放棄了首次下降ID 24行，它會更新，這就是好的。但ID 30行停留在實際位置（序列1）。
我該怎麼辦？
$("#table-2").tableDnD(
{
onDrop: function(table, row)
{
var rows = table.tBodies[0].rows;
var RowID = row.id.substr(3);
var RowIndex = $(row).index() + 1;
$.ajax({
data: { RowID:RowID, RowIndex:RowIndex },
type: 'POST',
url: 'files/update_slide_index.php',
success: function(data)
{
var result = $.trim(data);
$('#newsletterResult').html(result);
$('#newsletterModal').modal('show');
},
complete: function()
{
setTimeout(function()
{
location.reload();
}, 3000);
}
});
}
});
<?php
include_once("../../files/connect.php");
if(isset($_POST['RowID']))
{
$RowID = intval($_POST['RowID']);
$RowIndex = intval($_POST['RowIndex']);
$sql = "UPDATE slideshow SET slide_sorrend = '$RowIndex' WHERE slide_id = '$RowID'";
mysqli_query($kapcs, $sql) or die(mysqli_error($kapcs));
echo 'A kép sorrendje sikeresen megváltozott.';
}
else
{
echo 'Nincs ID';
}
?>
更新2：
也許這？
mysqli_query($kapcs, "UPDATE slideshow SET slide_sorrend = slide_sorrend + 1 WHERE slide_id != '$RowID'") or die(mysqli_error($kapcs));
請在您的問題所需的響應。我不確定你想得到什麼 –
我想知道我放下的那一排是哪一排。例如：aftr下降，該行是第一行，或其第二個... –
