在 config.js 中添加如下代码

CKEDITOR.on( 'dialogDefinition', function( ev ){		// Take the dialog name and its definition from the event data.		var dialogName = ev.data.name;		var dialogDefinition = ev.data.definition; 		// Check if the definition is from the dialog window you are interested in (the "Link" dialog window).		if ( dialogName == 'link' )		{			// Get a reference to the "Link Info" tab.			var infoTab = dialogDefinition.getContents( 'info' ); 			// Set the default value for the URL field.			// var urlField = infoTab.get( 'url' );			// urlField['default'] = 'www.example.xxxcom';						var protocolField = infoTab.get( 'protocol' );			protocolField['default'] = "";		}});
