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

值得补充的是，这个问题与先前的问题有关，并以此为基础:

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.
