【发布时间】:2012-07-31 15:41:12
【问题描述】:
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标签溢出。
<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>
如何限制子级在父级中的位置和大小。
