在codeigniter中将json数据从控制器发送到视图时出现错误

Question

以前我是从控制器发送一个值到视图，它成功获得。现在我想通过使用JSONdata发送两个值。

控制器

$batch_wise_stock =  sprintf('%0.2f',(!empty($pur_product_batch->purchase_qty)?$pur_product_batch->purchase_qty:0)-(!empty($sellt_prod_batch->sale_qty)?$sellt_prod_batch->sale_qty:0));
$batch_wise_rate = $pur_product_batch->rate;

$json_product[] = array('qty'=>$batch_wise_stock,'rate'=>$batch_wise_rate);
echo json_encode($json_product);

/p>

$.ajax( {
url: base_url + "invoice/invoice/batchwise_productprice",
method: 'post',
dataType: "json",
data: {
prod_id: prod_id,
batch_no:batch_no,
csrf_test_name:csrf_test_name,
},
success: function( data ) {
var obj = jQuery.parseJSON(data);
console.log(obj);
if (parseInt(data) >= 0) {
$(".available_quantity_" + sl).val(data.toFixed(2,2));
}else{
var message = "You can Sale maximum " + available_quantity + " Items";
toastr["error"](message);
$("#total_qntt_" + sl).val('');
var quantity = 0;
$("#total_price_" + sl).val(0);
for(var i=0;i<taxnumber;i++){
$("#all_tax"+i+"_" + sl).val(0);

}
}

}
});

误差

Uncaught SyntaxError: JSON.parse: unexpected character at line 1 column 2 of the JSON data

Answer 1

尝试遍历返回的数据…(稍后与obj比较)

$.each(data, function(index, value ){
$('#item_qty' + sl).val(value.qty); //console.log() or alert();
$("#item_price" + sl).val(value.rate);
});
