                var url = "<?php echo $this->baseUrl();?>/ajax/get-all";
                //var selecter_id = $(this).val();
                //alert(selecter_id);

                $.ajax({
                    url: url,
                    type: "POST",
                    success: function(data)
                    {
                        alert("success");
                        var obj = $.parseJSON(data);
                        console.log(obj);
                        if(obj.meta.code === '200')
                        {
                            alert("ok");
                            $.each(obj.data, function(i,v){
                                //alert(v.builder_name);
                                $("#browsers").append("<option value="+v.builder_project_id+">"+v.builder_name+"</option>");
                            });

                        }
                    },
                    error: function(error){
                           alert("Error"); 
                    }
                });
            });

getting the output till success after that alerting i.e ok.

my json response is like

{
    "meta": {
        "code": 200,
        "message": "SUCCESS"
    },
    "data": [
        {
            "s_no": 1,
            "builder_project_id": "389",
            "builder_name": "1 389 Sath Build Home",
    },
    {
            "s_no": 348,
            "builder_project_id": "4",
            "builder_name": "348 4 NA",
    }
    ]
}

I cant understand where i am doing mistake pls suggest in console getting Uncaught SyntaxError: Unexpected token

Your JSON output is invalid.

It is putting unnecessary commas at the last element of the array.

Observe, the removed comma after builder_name's values.

Corrected JSON:

$json = '{
    "meta": {
        "code": 200,
        "message": "SUCCESS"
    },
    "data": [
        {
            "s_no": 1,
            "builder_d": "389",
            "builder_name": "1 389 Sath Build Home"
    },
    {
            "s_no": 348,
            "builder_project_id": "4",
            "builder_name": "348 4 NA"
    }
    ]
}';
