本文实例讲述了YII视图整合kindeditor扩展的方法。分享给大家供大家参考,具体如下:
比较喜欢用kindeditor,YII上的版本比较旧,所以自己重新整了个扩展
先在protected\extensions下创建KEditor文件夹用来放文件,keSource里放kindeditor的源文件,然后建三个类KEditor、KEditorManage和KEditorUpload,KEditor是扩展的主文件,KEditorManage是用来浏览服务器文件的,KEditorUpload是用来示例接收上传文件的,

textareaOptions用来设置textarea的大小和样式,仅支持rows、cols和style
properties的各项跟js设置kindeditor的是一样的,上面的设置与下面用js设置的是一致,kindeditor原来有的项都可以设置
