There maybe hacking involved, however, I tried to minimize them.
To make wp_editor can work in dynamic html (which means without reload page, js changes the page structure), there are two major issues need to take care:
- tinymce
- qucik-tags
For [tinymce]:
a. need reset UI properly
solution is [remove mce instance] -> [get proper mce settings] -> [re-init a new mce instance]
in js code (id means textarea id):
tinymce.execCommand('mceRemoveEditor', true, id); var init = tinymce.extend( {}, tinyMCEPreInit.mceInit[ id ] ); try { tinymce.init( init ); } catch(e){}
b. need data write back to textarea before submit
- solution is [bind click to button] -> on submt :: [turn off mce] -> [turn on submit]
in js code:
jq('textarea[id="' + id + '"]').closest('form').find('input[type="submit"]').click(function(){ if( getUserSetting( 'editor' ) == 'tmce' ){ var id = mce.find( 'textarea' ).attr( 'id' ); tinymce.execCommand( 'mceRemoveEditor', false, id ); tinymce.execCommand( 'mceAddEditor', false, id ); } return true; });
For [Quick Tags]:
a. Re-init tags
- [Get settings] -> [setup mouse event] -> [re-init QTags]
b. Switch to proper tab (mce tab or quick tag tab)
[switch to current tab mode]
both above in js code:
if ( typeof(QTags) == 'function' ) { jq( '[id="wp-' + id + '-wrap"]' ).unbind( 'onmousedown' ); jq( '[id="wp-' + id + '-wrap"]' ).bind( 'onmousedown', function(){ wpActiveEditor = id; }); QTags( tinyMCEPreInit.qtInit[ id ] ); QTags._buttonsInit(); switchEditors.switchto( jq( 'textarea[id="' + id + '"]' ).closest( '.widget-mce' ).find( '.wp-switch-editor.switch-' + ( getUserSetting( 'editor' ) == 'html' ? 'html' : 'tmce' ) )[0] ); }
Also, please remember if you use ajax, every time post back mce UI, you need re-do [reset mce UI] and [Qtags] in you js. A easy solution is using js code in you post back html, and detect in php of:
$isAjax = defined( 'DOING_AJAX' ) && DOING_AJAX == true );
About default settings in js value:
mce :
tinyMCEPreInit.mceInit
qtags :
tinyMCEPreInit.qtInit
If you try to use default setting for widget mode, you need locate default settings.
To get widget template id, in js code:
function getTemplateWidgetId( id ){
var form = jQuery( 'textarea[id="' + id + '"]' ).closest( 'form' );
var id_base = form.find( 'input[name="id_base"]' ).val();
var widget_id = form.find( 'input[name="widget-id"]' ).val();
return id.replace( widget_id, id_base + '-__i__' );
}
So you can get settings by:
for mce:
var init; if( typeof tinyMCEPreInit.mceInit[ id ] == 'undefined' ){ init = tinyMCEPreInit.mceInit[ id ] = tinymce.extend( {}, tinyMCEPreInit.mceInit[ getTemplateWidgetId( id ) ] ); }else{ init = tinyMCEPreInit.mceInit[ id ]; }
For Qtags:
var qInit; if( typeof tinyMCEPreInit.qtInit[ id ] == 'undefined' ){ qInit = tinyMCEPreInit.qtInit[ id ] = jq.extend( {}, tinyMCEPreInit.qtInit[ getTemplateWidgetId( id ) ] ); qInit['id'] = id; }else{ qInit = tinyMCEPreInit.qtInit[ id ]; }

If anyone want use wp_editor in menu walk for admin, the principle should be the same.
If you have any question or better solut please comment, thanks.
