如何在CKEditor中退格和刪除？

Question

退格鍵和刪除鍵在CKEditor中如何工作？如果我在可編輯區域中有一個iframe，並將光標放在其旁邊，那麼點擊退格/刪除將刪除iframe /從中刪除其HTML代碼。

我無法得到的是這種行爲的代碼在哪裏？在退格的地方，範圍縮小到iframe，並被刪除。

請指出我在源代碼中發生這種情況的正確方向。

Answer 1

也有一些是刪除

oKeystrokeHandler.SetKeystrokes

，但我不關於行爲

var FCKEnterKey = function(targetWindow, enterMode, shiftEnterMode, tabSpaces) 
{ 
    this.Window   = targetWindow ; 
    this.EnterMode  = enterMode || 'p' ; 
    this.ShiftEnterMode = shiftEnterMode || 'br' ; 

    // Setup the Keystroke Handler. 
    var oKeystrokeHandler = new FCKKeystrokeHandler(false) ; 
    oKeystrokeHandler._EnterKey = this ; 
    oKeystrokeHandler.OnKeystroke = FCKEnterKey_OnKeystroke ; 

    oKeystrokeHandler.SetKeystrokes([ 
     [ 13  , 'Enter' ], 
     [ SHIFT + 13, 'ShiftEnter' ], 
     [ 8   , 'Backspace' ], 
     [ CTRL + 8 , 'CtrlBackspace' ], 
     [ 46  , 'Delete' ] 
    ]) ; 

    this.TabText = '' ; 

    // Safari by default inserts 4 spaces on TAB, while others make the editor 
    // loose focus. So, we need to handle it here to not include those spaces. 
    if (tabSpaces > 0 || FCKBrowserInfo.IsSafari) 
    { 
     while (tabSpaces--) 
     this.TabText += '\xa0' ; 

     oKeystrokeHandler.SetKeystrokes([ 9, 'Tab' ]); 
    } 

    oKeystrokeHandler.AttachToElement(targetWindow.document) ; 
}
