javascript - envia dados de form com ajax está em conflito com código que atualiza div sem refresh na página! como resolver

eltube2018 · Abril 7, 2019

Tenho um cod javascript pra enviar via ajax dados de dois forms pra uma pagina.php que envia pro banco de dados, tudo funciona bem.

porem ao ter adicionado um codigo pra atualizar uma div contendo boa oparte do site inclusive os formularios, o código e o carregamento normal da p´[agina ficam lentos, e atualiza normal tbm de tempos em tempos determinados, mas com esse conflito tbm acontece que se clico no submit, e aperto f5 ou simplesmente faço recarregamento manual da página toda, aparece caixa de texto dizendo que essa página já enviou dados e tal.

Como resolver esse conflito . meu teclado nao tem interrogação configurado.

Abaixo coloco os codigos javascript e PHP :

// start of PLAYER PLAY AND BUTTON CHANGES WHEN PRESSED
	function aud_play_pause() {
				var radiorockfm = document.getElementById("radiorockfm");
				if (radiorockfm.paused) {
				  $('#radiorockfmicon').removeClass('.button');
				  $('#radiorockfmicon').addClass('paused');
				  radiorockfm.play();
				} else {
				  $('#radiorockfmicon').removeClass('paused');
				  $('#radiorockfmicon').addClass('.button');
				  radiorockfm.pause();
			   }
			 }
// end of PLAYER PLAY AND BUTTON CHANGES WHEN PRESSED

Código PHP resumindo a principal parte:

Essa div class="playing-track"> essa div que está obviamente sendo recarregada sem refresh em toda a página, porém parece dar conflito com o ajax que envia os dados desses dos formularios, e pior após apertar o submit, se recarregar manualmente a janela, asparece mensagem dizendo que conteudo recarregado já foi enviado ou algo assim, vcs devem saber do que tou falando.

Tah f***, o jeito foi positionar em outro lutar e bagunçar meu layout, mas gostaria de entender pq isso acontece, e tentar repositionar para criar um layout abnsoluto em cima da ideia do site que eh este:

Entrar

Arquivado

javascript - envia dados de form com ajax está em conflito com código que atualiza div sem refresh na página! como resolver
