I made a javascript to assemble a card and fill with information from a json, I need to check if there is an image in the indexes of the json array so that if I don’t have it I can set a default image, but I’m not able to use if inside apprend to do this check.
$(function(){
carregar(0, 3, 'Chamadas/listarAnuncios.php');
$(document).on('click', '#carregarMais',function(){
var init = (jQuery('.anunciosJson').length);
carregar(init, 3, 'Chamadas/listarAnuncios.php')
});
function carregar(init, max, url){
var dados = { init : init, max : max };
if(init >= 3)
{
$('#img_loadBuscarAnuncio').fadeIn('slow');
}
$('#cardContainer').css("opacity", 0.4);
$.post(url, dados, function (data) {
$("#carregarMais").last().remove();
$('#img_loadBuscarAnuncio').fadeOut('slow');
$('#cardContainer').css("opacity", 1.0);
for(i = 0; i < data.dados.length; i++){
$("#cardAnuncios").append('<div class="anunciosJson">'
+'<a style="display: block; color: rgba(0,0,0,0.87);" href="#">'
+'<div style="box-shadow: 0 2px 5px 0 rgba(0, 0, 0, 0.16), 0 2px 10px 0 rgba(0, 0, 0, 0.12); overflow: hidden; margin-bottom: 6px;">'

}
console.info(data);
$("#cardAnuncios").append('<button id="carregarMais" class="btn right" style="background-color: #0097a7;" type="submit" name="action"><center>Carregar mais</center></button>');
$('#img_loadBuscarAnuncio').fadeOut('slow');
$('#cardContainer').css("opacity", 1,0);
var conta = $('<div class="anunciosJson">').length;
if(init == max)
{
$("#carregarMais").last().remove();
$('#img_loadBuscarAnuncio').fadeOut('slow');
$('#cardContainer').css("opacity", 1.0);
}
if(conta == data.totalResults) {
$("#carregarMais").hide();
}
}, "json");
}
});
wouldn’t be something like
+(data.dados[i].img !=null) ? data.dados[i].img : "outraimagem.jpg"?– Ricardo Pontual
