postMessageAll

Sends a message recursively to this form and every child form.

Parameters

name (string): The message name
data (any): The payload (may be null)

Returns: None (void)

Description

Walks the form tree recursively and invokes the onMessage handler on itself and every child form. It recurses deeper than postMessage(name, data, "*"), reaching children of children as well.

postMessage vs postMessageAll

Method	Delivery scope
`postMessage(..., "*")`	Itself plus directly embedded FormContainer children
`postMessageAll`	Itself plus every child form (deep recursion)

Example

// 현재 폼과 모든 자식 폼에 리프레시 요청
$form.postMessageAll("refresh", null);

// 테마 변경 전체 브로드캐스트
$form.postMessageAll("themeChanged", { dark: true });
