how to get two arrays from php using json,jquery ajax?

ajax, jquery, json, php

Solution

See if you are able to produce two object arrays of json then you can try with this:

    var data21,data22; 
    $.ajax({
        type: "GET",
        url: "customer_coverage.php",
        data: {id:id},
        contentType: "application/json",
        dataType: "json",
        success: function (data) {
            $.each(data, function(i, item){
               data21 = item.data21;
               data22 = item.data22;
            });
            initChart2(data21,data22);
        }
    });

and i am supposing if you are able to produce this:

[
 {
    "data21": {
        .........
    },
    "data22": {
        ........
    }
 }
]
