【问题描述】:
我正在使用jquery sortable plugin 拖放项目并设置它们的顺序。但我无法得到 Ajax 的响应。我想从js 调用控制器操作,这样当我拖放项目时,应该会有响应。拖放功能运行良好。
我试过这个:
我的观点:
<div class="status-index info">
<h1><?= Html::encode($this->title) ?></h1>
<?php // echo $this->render('_search', ['model' => $searchModel]); ?>
<p>
<?= Html::a('Create Status', ['create'], ['class' => 'btn btn-success']) ?>
</p>
<ul class="sortable_status">
<?php
$items = StatusType::find()->orderBy('order')->all();
//var_dump($items);exit;
//$content = array();
foreach ($items as $item) {
echo '<li class="text-items"><label for="item'.$item->order.'"><span class="items-number">'.$item->order.'</span></label>
<label id="item'.$item->order.'" />'.$item->title.'</label>
<br/>
</li>';
}
?>
</ul>
</div>
JS:
$(function () {
var LI_POSITION = 'li_position';
$("ul.sortable_status").sortable({
update: function(event, ui) {
//create the array that hold the positions...
var order = [];
//loop trought each li...
$('.sortable_status li').each( function(e) {
//add each li position to the array...
// the +1 is for make it start from 1 instead of 0
order.push( $(this).attr('id') + '=' + ( $(this).index() + 1 ) );
});
// join the array as single variable...
var positions = order.join(';')
//use the variable as you need!
alert( positions );
// $.cookie( LI_POSITION , positions , { expires: 10 });
}
/*handle : '.handle',
update : function () {
var order = $('.sortable_status').sortable('serialize');
$(".info").load("process-sortable.php?"+order);
} */
});
});
控制器:
public function actionSortable()
{
/* foreach ($_GET['text-items'] as $position => $item)
{
$sql[] = "UPDATE `status_type` SET `order` = $position WHERE `id` = $item";
}*/
if ( isset( $_COOKIE['li_position'] ) ) {
//explode the cockie by ";"...
$lis = explode( ';' , $_COOKIE['li_position'] );
// loop for each "id_#=#" ...
foreach ( $lis as $key => $val ) {
//explode each value found by "="...
$pos = explode( '=' , $val );
//format the result into li...
$li .= '<li id="'.$pos[0].'" >'.$pos[1].'</li>';
}
//display it
echo $li;
// use this for delete the cookie!
// setcookie( 'li_position' , null );
} else {
// no cookie available display default set of lis
echo '
empty
';
}
}

一个小建议——在实现这样的功能之前,也许最好先看看现有的解决方案?检查我的yii2-sortable 分机。
