This example shows how to use ghosting and manipulate the proxy element.
We are going to make the element
#yui_img resizable in all 8 directions.
Note: When you want to resize an element that requires the top and left sides to be positioned, it is best practice to make the element
Otherwise it will be positioned relative and the outcome will not be what you expected.
Since an image cannot have child nodes appended to it, the Resize Utility will auto wrap it with an element that can. See the API docs for more info on the wrap option.
For shorthand, we are using the
handles type of
All, which just simply means
t, r, b, l, tr, tl, br, bl. We are also using the config
knobHandles, this applies a class to the Resize element and styles all of the handles into the small knobs seen above.
In this instance we have also turned on the following options:
draggable, this will allow the element to be dragged.
ghost, this will apply a classname of
.yui-resize-ghostto the parent for styling with opacity.
status, this is what turns on the yellow tooltip that follows the mouse when resizing.
animate, turns on animation for the resize.
animateDuration, the duration of the animation.
animateEasing, the easing method to apply to the animation instance.
For this example, we want to make it look like the proxy is a copy of the image we are resizing.
We do this by subscribing to the
startResize Event, and manipulating the proxy element with normal DOM scripting.
All YUI 2.x users should review the YUI 2.8.2 security bulletin, which discusses a vulnerability present in YUI 2.4.0-2.8.1.
