我希望可拖动div的id在警告按钮中显示为逗号分隔列表,如果它们被放入droppable_box中。相反,每个拖动的div都会一个接一个地发出警报,而不是列表。
<script type="text/javascript">
$(document).ready(function(){
$( "#draggable1" ).draggable({ grid: [ 20,20 ] });
$( "#draggable2" ).draggable({ grid: [ 20,20 ] });
$( "#draggable3" ).draggable({ grid: [ 20,20 ] });
$( "#droppable_box" ).droppable({
drop: function( event, ui ) {
var currentId = $(ui.draggable).attr('id');
var stuff = [];
$.each($(ui.draggable), function(i,e) {
stuff.push(e.id);
});
var energy = stuff.join(", ");
var data = "X-Requested-With=XMLHttpRequest";
$('#myId').click(function(){
$.post (
"process.php",
data,
function(data)
{
alert(energy);
},
'html'
);
});
}
});
});
</script>
在html中有3个可拖动的div
<div id="draggable1" class="draggable_meal"></div>
<div id="draggable2" class="draggable_meal"></div>
<div id="draggable3" class="draggable_meal"></div>
我稍微更改了jquery并将其发布为here:
您可以查看视图来源。感谢。
在process.php中,它给了我1到3个数组,具体取决于我拖动的div数。我想使用
将$ _REQUEST对象推送到数组中foreach ($_REQUEST as $key => $value) {
array_push($stack,$value);
}
print_r($stack);
但它给了我1到3个数组,每个数组的键为零。如何从例如3个拖动的div中获取一个数组?
