In case anybody is interested, I wrote a solution for this using Prototype. In order to get the button to appear correctly, I had to specify extraPlugins: 'ajaxsave'
from inside the CKEDITOR.replace()
method call.
Here is the plugin.js:
CKEDITOR.plugins.add('ajaxsave',
{
init: function(editor)
{
var pluginName = 'ajaxsave';
editor.addCommand( pluginName,
{
exec : function( editor )
{
new Ajax.Request('ajaxsave.php',
{
method: "POST",
parameters: { filename: 'index.html', editor: editor.getData() },
onFailure: function() { ThrowError("Error: The server has returned an unknown error"); },
on0: function() { ThrowError('Error: The server is not responding. Please try again.'); },
onSuccess: function(transport) {
var resp = transport.responseText;
//Successful processing by ckprocess.php should return simply 'OK'.
if(resp == "OK") {
//This is a custom function I wrote to display messages. Nicer than alert()
ShowPageMessage('Changes have been saved successfully!');
} else {
ShowPageMessage(resp,'10');
}
}
});
},
canUndo : true
});
editor.ui.addButton('ajaxsave',
{
label: 'Save',
command: pluginName,
className : 'cke_button_save'
});
}
});
