默认值
使用defaultOptions对象，你可以重写上述任何属性或回调函数，就像下面的方式下：
$.cleditor.defaultOptions.width = 200;
$.cleditor.defaultOptions.height = 100;
$("#input").cleditor();
覆盖defaultOptions对象适用于所有新的编辑。.cleditor(options) Method

This is the core method for creating and selecting cleditor objects.
Examples
$("#input").cleditor({width:500, height:250});
$("textarea").cleditor();
var editor = $("#input").cleditor()[0];
var $editors = $("textarea").cleditor();
cleditor ObjectAn editor is composed of a main div element used to hold a toolbar, a text area and an iframe. The toolbar can hold multiple groups which in turn hold multiple buttons.
The cleditor object is created and exposed using the .cleditor(options) method described above. It defines a single editor instance and supports the following properties and methods.
Properties
These properties should be considered readonly.
.$area – The textarea wrapped in a jQuery object.
.$frame – The iframe wrapped in a jQuery object.
.$main – The main div wrapped in a jQuery object – When moving an editor, this is the DOM element to re-parent.
.$toolbar – The toolbar div wrapped in a jQuery object.
.disabled – True if the editor is currently disabled; otherwise false.

.options – The options used to create the editor.

.blurred() – shortcut method used to trigger the blurred event.
.change(handler) – shortcut method used to bind the change event.
.change() – shortcut method used to trigger the change event.
.clear() – Clears the contents of the internal textarea and iframe.
.disable(disabled) – Disables or enables the editor. Pass in true to disable or false to enable.
.execCommand(command, value, useCSS, button) – Executes a design mode command using the supplied value. If useCSS is true, CSS will be used to style the markup when possible.

.focus() – Sets input focus to the editor.
.focused(handler) – shortcut method used to bind the focused event.
.focused() – shortcut method used to trigger the focused event.
.hidePopups() – Hide any popups currently showing in any editor.

.select() – Selects the entire contents of the editor.
.selectedHTML() – Returns the editor’s current selection as an HTML formatted string.
.selectedText() – Returns the editor’s current text selection as a string.
.showMessage(message, button) – Displays a popup message under the button or centered under the toolbar if button is omitted.

Properties
.defaultOptions – Contains the default optional parameter values used in the creation of new editors.

By default, CLEditor will execute the command using the value and useCSS properties found on the data parameter.
.popupClick(event, data) – This handler is called when an element in the popup is clicked and should return false to prevent CLEditor from executing the command on the data object parameter. By default, CLEditor will execute the command using the value and useCSS properties found on the data parameter.
The data object passed into the above callback functions contains the following properties.
.editor – The cleditor object containing the clicked button.
.button – The clicked button’s div element.
.buttonName – The name of the clicked button.
.popup – The popup div element.
