[ExtJS]WYSIWYG所視即所得網頁編輯器外掛 with CKEditor

ExJS所提示的HtmlEditor非常簡單,一般來說算夠用了,不過還是有很多狀況無法適用,所幸ExtJS可利用擴充的方式來使用其它的WYSIWYG編輯器,TinyMCE是個很好的選擇,FCKEditor也不錯,現在重新被制作改名成CKEditor,以下的範例是使用CKEditor來砍進ExJS當成它的HtmlEditor。

                         {
                             //alert(123);
                             Form.getForm().submit();
                         }//.createDelegate(Form.getForm())
                     }],
        renderTo: bd
    });
});

其中要開啟CKEditor的功能可以從toolbar這個參數裡設定toolbar:’Full’是全部啟用,toolbar:’Basic’是只有簡單功能,跟內建的ExtJS HtmlEditor有點像,以下是全部的項目,可以選擇要放置的位置及啟用的功能

toolbar:[['Source'/*,'-','Save','NewPage','Preview','-','Templates'*/],
                             ['Cut','Copy','Paste','PasteText','PasteFromWord','-','Print', 'SpellChecker', 'Scayt'],
                             ['Undo','Redo','-','Find','Replace','-','SelectAll','RemoveFormat'],
                             /*['Form', 'Checkbox', 'Radio', 'TextField', 'Textarea', 'Select', 'Button', 'ImageButton', 'HiddenField'],*/
                             ['BidiLtr', 'BidiRtl'],['Link','Unlink','Anchor'],
                             '/',
                             ['Bold','Italic','Underline','Strike','-','Subscript','Superscript'],
                             ['NumberedList','BulletedList','-','Outdent','Indent','Blockquote','CreateDiv'],
                             ['JustifyLeft','JustifyCenter','JustifyRight','JustifyBlock'],
                             
                             ['Image','Flash','Table','HorizontalRule','Smiley','SpecialChar','PageBreak'],
                             '/',
                             ['Styles','Format','Font','FontSize'],
                             ['TextColor','BGColor'],
                             ['Maximize', 'ShowBlocks','-'/*,'About'*/]

                             ],
