Query the database send and use javascript

Question

My difficulty is after sending to java script how to separate each record:

Example: In my code I’m running this function:

$culturas=array();
        $resultado=mysqli_query($conexao,"select *from mandioca_iea where id_cult=1");
            while($cultura=mysqli_fetch_assoc($resultado))
            {
                array_push($culturas,$cultura);
            }
        echo json_encode($culturas);

And to receive the consultation:

$.post('envia.php', {nome: nome}, function(resposta) {}

So far so good, he sends Javascript something like this:

On my console returned this :[{"iea_id":"1","man_ins_area_00":"0","man_ins_prod_00":"0","man_ins_area_05":"0"‌​, "man_ins_prod_05":"0","man_ins_area_10":"0","man_ins_prod_10":"0","man_ins_area_‌​13":"0", "man_ins_prod_13":"0","id_cid":"1","id_cult":"1"}, {"iea_id":"2","man_ins_area_00":"0","man_ins_prod_00":"0","man_ins_area_05":"0", "man_ins_prod_05":"0","man_ins_area_10":"0","man_ins_prod_10":"0", "man_ins_area_13":"0","man_ins_prod_13":"0","id_cid":"2","id_cult":"1"}]

Where :"iea_id":"1" and "iea_id":"2",are two different records.

My doubt is if there is any way access the "records" (because in this format are no longer records),separately,as if it were a vector,for mounting a chart?

EDITING WITH THE ERROR:

Complete code being used:

<script type="text/javascript" language="javascript">
$(function($) {
    $("#formulario").submit(function() {
        $("#status").html("<img src='loader.gif' alt='Enviando' />");
        $.post('envia.php', {nome: nome}, function(resposta) {
    for(var i=0; i<resposta.length; i++) {
        var registro = resposta[i];
        console.log(registro.iea_id);
    }
});
    });
});
</script>

Answer 1

You have an array of objects. Brackets define the array, and each pair of { and } sets an object (one for each record). You access the records by looping the array:

$.post('envia.php', {nome: nome}, function(resposta) {
    for(var i=0; i<resposta.length; i++) {
        var registro = resposta[i];
        console.log(registro.iea_id); // 1 na primeira passada, 2 na segunda
    }
});

It’s that simple, inside the loop you can access the fields by name/key.

As for the chart setup, you can reprocess the data in Javascript and reorganize it to pass to the graphics generator, or already pass in the right format since PHP. It depends on whether or not you need the complete data (and organized by record) in JS.
