jQuery中可调整大小的可拖动对象.可能的? [英] Resizable, draggable object in jquery. Possible?
问题描述
我想要一个既可调整大小又可拖动的对象.我需要:
I want to have an object which is both resizable and draggable. I'll need:
- X
- Y
- 大小
该对象.
这可能吗?
在 http://www.jsfiddle.net/davidThomas/DGbT3上有一个示例/1/获取可拖动对象的x和y.我还应该如何调整其大小?
There is an example on http://www.jsfiddle.net/davidThomas/DGbT3/1/ which gets the x and y of the draggable object. How can I also make it resizable?
谢谢
It's worth adding that this question is related to, and built on, this previous question: How to get the position of a draggable object?
推荐答案
确定是... jQuery UI 适用于复杂的行为，例如拖放，调整大小，选择和排序.
Sure it is... jQuery UI is good for complex behaviors like drag and drop, resizing, selection and sorting.
使用jQuery UI，您可以:
With jQuery UI you can:
- 拖动
- 拖放
- 调整大小
- 排序
您可以将所有东西链接在一起.
And you can everything chain together.
包含jquery-ui.css文件对于调整大小功能很重要.
It is important for the resize feature that you include the jquery-ui.css file.
