I'm trying to access all brands and values for dropdown menu but I couldn't that with this way.
<select id="secim">
</select>
var data = [
{
"products": "Cars",
"brands_values" : [
{"brand":"fiat","value":1},
{"brand":"bmw","value":2}
]
}
];
$.each(data, function(i, item) {
$('#secim').append($('<option>', {
value: item.brands_values.value,
text: item.brands_values.brand
}));
});
How could I do? Thank you
Just add another loop for the brands:
var data = [ { "products": "Cars", "brands_values" : [ {"brand":"fiat","value":1}, {"brand":"bmw","value":2} ] }]; $.each(data, function(i, item) { if (item.brands_values) { item.brands_values.forEach(brands => { $('#secim').append($('<option>', { value: brands.value, text: brands.brand })); }); } });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <select id="secim"> </select>
Note: You may want to use native .forEach
in that case, since it is enough. I had performance issues with jQuery.each()
in the past so I avoid it whenever I can( check this ):
data.forEach(item => {
if (item.brands_values) {
item.brands_values.forEach(brands => {
$('#secim').append($('<option>', {
value: brands.value,
text: brands.brand
}));
});
}
});
$.each(data, function(i, item) {
$.each(item.brands_values, function(j, brand){
$('#secim').append($('<option>', {
value: brand.value,
text: brand.brand
}));
});
});
You need another iteration - of course the first "loop" is not very elegant, but this is due to the given data format.

Iterate over brand values and not just data. So that you can acces each brand and value.
var data = [ { "products": "Cars", "brands_values" : [ {"brand":"fiat","value":1}, {"brand":"bmw","value":2} ] } ]; $.each(data[0].brands_values, function(i, item) { $('#secim').append($('<option>', { value: item.value, text: item.brand })); });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <select id="secim"> </select>
First create a list of brand_values
from data
by using a #reduce()
function. Then pass it as items
to your $.each
.
See demo below:
var data = [{ "products": "Cars", "brands_values": [{ "brand": "fiat", "value": 1 }, { "brand": "bmw", "value": 2 } ] }]; var items = data.reduce(function(p,c){ c.brands_values.forEach(function(e){ p.push(e); }); return p; },[]); $.each(items, function(i,item) { $('#secim').append($('<option>', { value: item.value, text: item.brand })); });
