完全な住所が認識された場合、codeAddress()GoogleマップのJavaScript APIを介して住所を完成させ、グローバルな js-variable を設定するjs関数があります。valid = trueまた<p:inputText>、完成したアドレスで a の値を更新します。
今<p:commandButton>、欲しいものがある
- 実行する
codeAddress() valid = trueフォームを送信すると、住所が<p:inputText>保存されaddressBean、- 次のページに移動
valid = falsejsf-validator メッセージをトリガーする場合
valid残念ながら、次のページかどうかを判断するための重要な値として、私の設定はまだ機能しません。値が Bean に送信されるのが遅すぎるようです。
これは私のjsfコードです:

これは bugMaps.js です:
