# Option: save_callback

This option enables you to add custom logic to be executed when the contents is extracted/saved. This custom logic can then modify the contents before it's submited to a serverside page. This can be useful if you want to do your own regexp cleanups and so forth. The format of this function is: saveContent(element_id, html, body). Where element id is the form element/div id of the editor and HTML is the HTML contents after the built in cleanup process has executed. This function should return the new HTML contents.

### Example of usage of the save_callback option:

    function myCustomSaveContent(element_id, html, body) {
    	// Do some custom HTML cleanup
    	html = html.replace(/a/g,'b');

    	return html;
    }

    tinyMCE.init({
    	...
    	save_callback : "myCustomSaveContent"
    });
