php - 错误缺失；通过jquery发送序列化xml时jquery中的before语句

标签 php jquery xml json

我在下面代码的 var data =<?php echo serialize($msg);?>; 行上收到此错误。控制台还会引发数据未定义错误。如果在数据两边加引号，那么这个错误就会消失，但第一个错误仍然存​​在。

//Raw xml
    $result = curl_exec($ch);
    curl_close($ch);
    $xml = simplexml_load_string($result);
     return $xml;
    } 
?>    
   <head>
   <script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js">
   </script>
   </head>
   <body>
   <script type="text/javascript"> <?php $msg = searchResults('windows');?>;
   var data ="<?php echo serialize($msg);?>";
   </script>
   <script type="text/javascript">
     $(document).ready(function() 
    {
       $.ajax({
       url: "script.php",
       type: "POST",
       data: data,
       success: function(){
       alert("success");
       }
      });
      return false;
     });
    </script>
    </body>
    </html>

我试图查看但无法找出任何问题

这是 script.php

<?php
var_dump($_POST);
?>

这是来自 Twitter 的 xml

这是我的 json 等效代码，但它不起作用。我把它放在这里是因为很多人(如果不是所有人)都推荐我将 json 添加到此代码中，即 OP，实际上是我想要的，但是 OP 将 xml 发送到 php，因为 json 之前对我不起作用' *此代码不会引发控制台错误，但会输出失败警报 *curl 正在发送结果，我已经在测试 php block 中进行了测试在 HTML 中的 ajax 之前。 

 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
 "http://www.w3.org/TR/html4/strict.dtd">

 <html>
 <?php
 function searchResults($q) {

  $host = "http://search.twitter.com/search.atom?q=" . urlencode( $q ) . "&rpp=100";
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, $host);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);

//Raw xml
  $result = curl_exec($ch);
  curl_close($ch);
  $xml = simplexml_load_string($result);
  return json_encode($xml);
  } 
 ?>
 <head>
 <script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js">
 </script>
 </head>
 <body>
 <script type="text/javascript"> var msg_top = <?php echo searchResults('windows');?>;
 </script>
 <script type="text/javascript">
$(document).ready(function() 
{
   $.ajax({
   url: "script.php",
   type: "POST",
   dataType: "json",
   data: msg_top,
   success: function(msg){
   alert("success");
  }
 });
alert("failure");
});
</script>
</body>
</html>

最佳答案

尝试一下 <罢工>

<罢工> 
var data="<?php echo json_encode(serialize($msg));?>";

<罢工>

编辑:抱歉，json_encode()函数会自动将引号添加到字符串中，因此代码应如下所示:

var data=<?php echo json_encode(serialize($msg));?>;


第一个 ; 之后有一些多余的分号( ?> ) ，你应该删除它。
