How to read JSON response while using $.post to send & receive data to PHP alongwith done & fail functions

PHP响应：

$Result['sendtoshopnumber'] = 'SH-101';
echo json_encode($Result);

我想在请求成功保存到数据库后向用户显示这个商店编号。

Jquery代码：

var jqxhr = $.post("send_item.php", 
{ 
    ItemID: 120032,
    Qty : 192 
} , 'json')
.done(function(data) {
        alert('your item is sent to shop no. = '+data.sendtoshopnumber);     
         ***here it alerts : UNDEFINED*** 

})
.fail(function() {
    alert( "failed" );
});

console.log显示了所需内容，但我无法读取并在javascript中使用。console.log输出显示：｛"sendtoshopnumber"：SH-101｝

尝试将其添加到done块中：

.done(function(data) {
    data = JSON.parse(data);
    console.log(data);
    alert('your item is sent to shop no. = '+data.sendtoshopnumber);   
})

然后在PHP中：

$Result['sendtoshopnumber'] = 'SH-101';
echo json_encode($Result);
exit;
