从右上角成长div？ [英] Grow div from top right corner?

问题描述

我有一个需要互动的元素网格。当其中一个div被点击时，它将增长到更大的大小。对于大多数元素，从右下角生长一个div是可以接受的：

I have a grid of elements that need to be interactive. When one of the divs is clicked, it will grow to a larger size. For most elements "growing" a div from the bottom right corner is acceptable:

$(.my-div).animate({ width: "379px", height: "204px" });

但是，在某些情况下，从右下角的生长其余的应用程序。

However, there are some cases in which "growing" from the bottom right won't work with the rest of the application.

例如，我可能需要从右上方增长。有任何想法吗？我喜欢简单的动画到一个新的宽度/高度，但我不知道它是否可以实现除了从右下角拖动效果。

I may need to grow from the top-right, for example. Any ideas? I like the simplicity of animating to a new width/height, but I'm not sure if it can achieve an effect other than dragging from the bottom-right corner.

提前感谢：）

推荐答案

有几种方法可以做到，无论是使用jQuery动画，转换。他们会像

There are a couple ways you could do it, either with jQuery animate like you mentioned, or CSS transitions. They would look something like

.child.clicked {
  height: 100px;
  width: 300px;
  transition: width 2s, height 2s;
-moz-transition: width 2s, height 2s;
-webkit-transition: width 2s, height 2s; 
-o-transition: width 2s, height 2s; 
}

或

  $('.child2').click(function() {
  $(this).animate({
    width: ['300px', 'swing'],
    height: ['100px', 'swing']
      }, { duration: "slow", easing: "easein" });
  });

有许多缓动属性和事情调整，直到你得到它完全如何你想要的。

There are a number of easing properties and things to tweak until you get it exactly how you want.
