我有一个可拖动的 div 标签，我希望它在被拖动时不会从其父级溢出。

<script>
    $('.children').resizeable().draggable();//from jquerUI
</script>

<style>
    .parent{
        overflow: hidden;
        position: relative;
        width: 1000px;
        height: 1000px;
    }
    .children{
        width: 100px;
        height: 100px;
        position: absolute;
    }
</style>

<div class="parent">
   <div class="children"><div>
</div>

如何限制子项在父项中的位置和大小。
