I'm trying to filter a JSON with category but I'm not getting it.
I have 3 checkboxes and when I select them they should filter a json as selected. and when I uncheck a checkbox it should filter only those that are selected. If no checkbox is selected it should return empty [] .
And when I select a checkbox and uncheck it it only returns [] .
Follow the code in JSFiddle
Assuming that it is necessary to filter the sections that contain the flight of the selected company, you could simplify the filter to check for flights in the selected sections:
function filtro(valor, selecionado) {
json.aPesquisa.forEach(function(item) {
if (selecionado) {
item.trecho.forEach(function(trecho) {
trecho.voo.forEach(function(voo) {
if (voo.cia.nm == valor) {
categoriaList.push(voo);
}
})
})
}
})
$("#resultado").html(JSON.stringify(categoriaList));
}
