本文實例講述了YII視圖整合kindeditor擴展的方法。分享給大家供大家參考，具體如下：
比較喜歡用kindeditor,YII上的版本比較舊,所以自己重新整了個擴展
先在protected\extensions下創建KEditor文件夾用來放文件，keSource里放kindeditor的源文件，然后建三個類KEditor、KEditorManage和KEditorUpload，KEditor是擴展的主文件，KEditorManage是用來瀏覽服務器文件的，KEditorUpload是用來示例接收上傳文件的，

textareaOptions用來設置textarea的大小和樣式，僅支持rows、cols和style
properties的各項跟js設置kindeditor的是一樣的，上面的設置與下面用js設置的是一致，kindeditor原來有的項都可以設置
