使用Ajax将数组发送到PHP脚本

Question

我有函数.push制作的数组.在数组中是非常大的数据.如何将此发送到PHP脚本？

   dataString = ??? ; // array?
   $.ajax({
        type: "POST",
        url: "script.php",
        data: dataString, 
        cache: false,

        success: function(){
            alert("OK");
        }
    });

script.php的:

  $data = $_POST['data'];

  // here i would like use foreach:

  foreach($data as $d){
     echo $d;
  }

这是怎么回事？

Answer 1

将数据字符串编码为JSON.

dataString = ??? ; // array?
var jsonString = JSON.stringify(dataString);
   $.ajax({
        type: "POST",
        url: "script.php",
        data: {data : jsonString}, 
        cache: false,

        success: function(){
            alert("OK");
        }
    });

在你的PHP中

$data = json_decode(stripslashes($_POST['data']));

  // here i would like use foreach:

  foreach($data as $d){
     echo $d;
  }

注意

当您通过POST发送数据时,它需要作为键值对.

从而

data: dataString

是错的.相反:

data: {data:dataString}

Answer 2

 dataString = [];
   $.ajax({
        type: "POST",
        url: "script.php",
        data:{data: $(dataString).serializeArray()}, 
        cache: false,

        success: function(){
            alert("OK");
        }
    });
