Question

AJAx脚本要么没有连接到testData.php，要么无法从testData.php中提取数据。无法隔离问题，任何帮助将不胜感激。

我有2个文件

index.php - AJAX脚本所在的位置以及我想要的数据显示在getdiv标记中。
textData.php - 使用mysql db来提取数据。这个脚本有效，我在底部复制/粘贴结果。

我认为问题出在AJAX脚本的某个地方。如果不能在div标签中显示信息，它不会提取信息。

testData.php - 数据库脚本和结果：

<?php
require_once('dbconv2.php');
$dbcon1 = Connection::getConnection();
    try {   $stmt = $dbcon1 ->query("SELECT 
                          click_count.page_ur, 
                          click_count.page_count
                     FROM click_count
                     ");                
                $testArray = $stmt->fetchAll(PDO::FETCH_ASSOC); 
                echo $row = $stmt->rowCount();              
            } 
            catch(PDOException $e) 
            {    echo $e->getMessage(); }   
var_dump($testArray); 

echo json_encode($testArray);
?>

array (size=7)
  0 => 
    array (size=2)
      'page_ur' => string 'test record page1' (length=17)
      'page_count' => string '1' (length=1)
  1 => 
    array (size=2)
      'page_ur' => string 'test record page2' (length=17)
      'page_count' => string '4' (length=1)
  2 => 
    array (size=2)
      'page_ur' => string 'test record page3' (length=17)
      'page_count' => string '3' (length=1)

[{"page_ur":"test record page1","page_count":"1"},{"page_ur":"test record page2","page_count":"4"},{"page_ur":"test record page3","page_count":"3"},{"page_ur":"test record page5","page_count":"7"},{"page_ur":"test record page4","page_count":"9"},{"page_ur":"test record page6","page_count":"6"},{"page_ur":"test record page7","page_count":"2"}]

index.php - AJAX脚本

  <body>       
    <div id="getdiv"> </div>

     <div id="questionButton">
      <form method="POST" name="form_questions" action="">         
        <BUTTON class="btn_get" id ="btn_get" NAME="btn_get">getInfo</BUTTON>        
      </form>
    </div>
    <script src="http://code.jquery.com/jquery-latest.js"></script>
    <script>       
      $(document).ready(function() { 
        $('#btn_get').on('click', function(e) { 
          $.ajax({
            type: 'GET',
            cache: false, 
            url: 'testData.php',
            dataType: 'json',
            success:function(info){  
             $("#getdiv").html(info[0].page_ur);
             }
          });
          e.preventDefault();
          });         
      });                  
    </script> 
  </body>

AJAX不会从db中提取或显示数据集
