什么是翻转图像
翻转图像的意思是当鼠标移到图像上时图像发生变化。例如 (把鼠标放到下图上)
由于事件属性可执行 javascript，使用事件属性创建移入效果。注意在Editor Profile中要打开这一功能。打开后在图像管理其中才能显示翻转选项卡。.
As event attributes are able to execute javascript, these should only be enabled in profiles assigned to trusted users.
To enable Event Attributes
-
From the JCE Control Panel, click on the Editor Profiles button, then click on a profile to edit, eg: "Default"
-
Click on the Editor Parameters tab, then on the Advanced tab.
-
Set the Allow Event Attributes option to Yes. The Allow Event Attributes option will not be visible but will automatically be enabled if the Allow Javascript option is enabled.
The Rollover Image Tab
The Rollover tab contains two input fields, Mouseover and Mouseout.
Mouseover 鼠标移入
Represents the onmouseover event attribute. This is the image displayed when the mouse cursor is placed over the image.
Mouseout 鼠标移出
Represents the onmouseout event attribute. This is the image displayed when the mouse cursor is moved off the image. This is also usually the defualt image.
Create a Rollover image
- Select the image that is to be the default image, ie: the one that is displayed in the content item.
- Click the Rollover Image tab.
- Select the image that you would like as the mouse over image.
- You can now go back to the Image tab and adjust the parameters as required.
