使用此插件，您可以更改列表的顺序或表行的顺序(这就是我的情况).例如，使用鼠标将第四行拖动到第二个位置.宽度为插件方法 sort.sortable("serialize")您可以访问新订单.

如何使用 sortable("serialize")通过 $.post 将新订单发送到php脚本?

How to use sortable("serialize") to send the new order via $.post to the php script?

HTML:

<table class="tablesort">
<tbody>
<tr data-id="39"><td>item 1</td></tr>
<tr data-id="37"><td>item 2</td></tr>
<tr data-id="40"><td>item 3</td></tr>

</table>

JavaScript:

JavaScript:

// Initialize the plugin
var sort = $(".tablesort").sortable({

  // After changing the order           
  onDrop: function ($item, container, _super) {
    var myObject = sort.sortable("serialize");

    // How to prepare *myObject* for sending?

    $.post('myurl.php', {blah:myObject}, function(){});
});

推荐答案

要通过$ .POST发送新订单，只需执行以下操作:

To send your new order via $.POST just do:

var dataToSend = sort.sortable("serialize").get();
$.post("ajax-sort.php", {test:dataToSend}, function(data){});

在ajax-sort.php上，您收到类似以下内容的信息:

On ajax-sort.php you recieve something like:

[test] => Array
        (
            [0] => Array
                (
                    [children] => Array
                        (
                            [0] => Array
                                ([id] => 39)

                            [1] => Array
                                ([id] => 37)

                            [2] => Array
                                (
                                    [subContainer] => false
                                    [id] => 38
                                )

                            ... snip ...
                        )
                )
        )
)

如果要更改此数组的结构，请覆盖插件中的 serialize()方法.

If you want to change the structure of this array, override the serialize() method in the plugin.

您将在此处找到自定义的serialize()方法的示例: http://johnny.github.io/jquery-sortable/#limited-target

You will find an example of a customized serialize() method here: http://johnny.github.io/jquery-sortable/#limited-target
