I searched everywhere but did not find an exact definition.
Here's my function and the excerpt from my HTML where DropDownList is created:
function carregaSubCategoria(valor) {
$.ajax({
url: '/parceiros/subcategoria/lists-subcat',
type: 'get',
data: {
id: valor
},
dataType: 'JSON',
success: function(data) {
var $teste = $('#subcategoria');
$teste.empty();
$teste.append($("<option></option>").attr("value", '').text('Selecione'));
$teste.each(data, function(value, key) {
$teste.append($("<option></option>").attr("value", value).text(key));
});
},
error: function(data) {
alert("oi errado");
},
});
}<div id="div_categoria">
<label class="label-control">Categoria</label>
<select name="ofe_cat_id" id="ofe_cat_id" class="form-control" onchange="carregaSubCategoria($(this).val())">
<option value="">Selecione</option>
<?php foreach ($categorias as $categoria) {
echo "<option value='".$categoria->cat_id."'>".$categoria->cat_nome."</option>";
} ?>
</select>
</div>
<div id="div_subcategoria">
<label class="label-control">Subcategoria</label>
<select name="subcategoria" id="subcategoria" class="form-control">
<option value="">Selecione</option>
<?php foreach ($subcategorias as $subcategoria) {
echo "<option value='".$subcategoria->sub_id."'>".$subcategoria->sub_nome."</option>";
} ?>
</select>
</div>Here's a portion of the JSON file:
[
{
"sub_id":2,
"sub_cat_id":3,
"sub_cod":"00020002",
"sub_nome":"Terror",
"sub_desc":"Filmes de Terror"
},
{
"sub_id":3,
"sub_cat_id":3,
"sub_cod":"00030003",
"sub_nome":"Aventura",
"sub_desc":"Filmes de Aventura"
}
]
I'm trying to run this code, but it keeps bringing me the error:
TypeError: callback.call is not a function
