通过客户端从服务器检索数据库

Question

我正在尝试从另一个php页面中检索数据，因为这是一个ajax，这个调用发布数据，但没有给出响应plz建议一些想法，我错了。

这是我的ajax：

    function loadedit(){


      if (window.XMLHttpRequest) {
        // code for IE7+, Firefox, Chrome, Opera, Safari
        xmlhttp=new XMLHttpRequest();
      } else { // code for IE6, IE5
        xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
      }
      xmlhttp.onreadystatechange=function() {
        if (xmlhttp.readyState==4 && xmlhttp.status==200) {
          document.getElementById("ajaxdiv").innerHTML=xmlhttp.responseText;
        }
      }
      xmlhttp.open("POST","editedit.php",true);
      xmlhttp.send();
    }

    loadedit function will be called on link click.

client.php：

<div class="menuleft">
<a class="menucontent" align="middle" href="http://localhost/DlfIn/home.php">Add</a>
<a class="menucontent" align="middle" onclick="loadedit()">Edit</a>
<a class="menucontent" align="middle" href="http://localhost/DlfIn/home.php">LogOut</a>
</div>
    <div id="ajaxdiv">
    </div>

editedit.php：

    <?php
    ini_set('display_errors', 1);
    ini_set('display_startup_errors', 1);
    error_reporting(-1);
    include 'config.php';

        $result = mysqli_query($con,"select * from images");

        //return the array and loop through each row
        if(count($result) > 0){
       echo "<table style='width:300px' border='1'>
    <tr>
      <th></th>
      <th>Title</th>
      <th>Description</th>
      <th>image</th>
      <th>select</th>
    </tr>";
        while ($row = mysqli_fetch_array($result)) {
         $title=$row['title'];
        $name=$row['name'];
        $id=$row['id'];
        $description=$row['description'];
        echo "<tr>";
        echo "<td><input type='checkbox' name='checkbox[]' id='checkbox[]' value=".$id."></td>";
        echo "<td><textarea  rows='1' >".$title."</textarea></td>";
        echo "<td><textarea  rows='1' >".$description."</textarea></td>";
        echo "<td><img width='100' height='100' src='images/".$name."'</td>";
        echo "<td><input type='button' id='sub' value='update'></button><input type='button' id='sub' value='delete'></button></td></tr>";
        }
        echo "<tr>
      <td colspan='4' align='center' bgcolor='#FFFFFF'><input name='delete' type='submit' id='sub' value='Delete'></td>
     </tr>
    </table>";  
    }
    ?>
