I made a code in Java in which I make requests in php and with the return of a json I populate my html, the problem is that at a certain moment I need to execute the Java code but I am not able to make it stop, the $.post is triggered at the click of a button, but I did find that $.post is called twice in 1 click. Note: I tried for Avascript with Return, but $.post is called again
$(document).on('click', '#btn_filtrarAnuncio',function(evento){
var combo = document.getElementById("busca_anuncio_categoria");
var categoria = combo.options[combo.selectedIndex].value;
var comboEstado = document.getElementById("busca_anuncio_estado");
var estado = comboEstado.options[comboEstado.selectedIndex].value;
evento.preventDefault();
carregar(0, 3, categoria, 'Chamadas/listarAnuncios.php');
document.getElementById('cardAnuncios').innerHTML = "";
$(document).on('click', '#carregarMaisFiltro',function(){
var init = (jQuery('.anunciosJsonFiltro').length);
carregar(init, 3, categoria,'Chamadas/listarAnuncios.php')
});
function carregar(init, max, categoria, url){
var dados = { init : init, max : max, categoria : categoria, estado : estado };
if(init >= 3)
{
$('#img_loadBuscarAnuncio').fadeIn('slow');
$('#cardContainer').css("opacity", 0.4);
}
$.post(url, dados, function (data) {
$("#carregarMaisFiltro").last().remove();
for(i = 0; i < data.dados.length; i++){
var img = data.dados[i].img ? data.dados[i].img : "../anuncio-padrao.png";

Blz friend I will test this way and I already give you a feedback, the strange thing is that the first time I use the function of the click of the search button works normal, only if I press this button again it happens to use the $.post 2 times
– Reignomo
It is because by clicking the first time the second event does not exist, already in the second click it has already been created and will fire 2 times.

Good morning, I did this way that you suggested and it worked perfectly, thank you very much, I’m 3 days standing at this point you saved me
