Question

我在调用特定对象时遇到问题。例如，我想调用mydata.title

我的php里面有ff（这只是代码的一部分）

while($row = $DB->result->fetch_assoc()){

        $Fthis[] = array( 

            "title" => $row["title"],
            "subtitle" => $row["subtitle"],
            "dates" => $row["dates"],
            "Author" => $row["Author"],
            "content" => $row["content"],
            "himgsrc" => $row["himgsrc"]
        );

          array_push($marxarray, $Fthis);
    }

    echo json_encode($marxarray);

然后我在我的js中有这个AJAX。

$.ajax({
  url: 'editer.php',
  type: 'POST',
  data: { id: blogid },
  success: function (data) {
    var mydata= JSON.parse(data);
    console.log(mydata);
    alert(mydata.title);
  }
});

为什么警报返回undefined？如果我查看日志，我可以看到数组已经正确传递，所以php没问题（我认为）。

这里看起来是怎样的。

我检查了你的图片，你必须使用数组索引
