我需要backbone.js吗？(Is backbone.js necessary for me?)

 首先，你需要修改你的php脚本 ： 
 
echo "<li><a class='clsPostData' data-sensorid='".$result['oxi_sensorid']."' data-apikey='".$result['oxi_apikey']."' href='#'>".$local."</a></li>";
 
 和你的JQuery代码： 
 
$(function(){
    $('.clsPostData').click(function(e){
          e.preventDefault();
          var objPost = {};
          objPost.api = $(this).data('apikey');
          objPost.sensor = $(this).data('sensorid');
          $.ajax({
             url: 'getData.php',
             type: 'post',
             data: objPost
          }).done(function(responseFromPhp){
             //Do something with the response, like
             alert(responseFromPhp.message);
          });
    });
});
 
 你的getData.php脚本： 
 
<?php
   $apikey = $_POST["api"];
   $sensorid = $_POST["sensor"];

   $response["message"] = "Grettings from php, we receive your sensorid: ".$sensorid;
   echo json_encode($response);
?>

First, you need to modify your php script:
 
echo "<li><a class='clsPostData' data-sensorid='".$result['oxi_sensorid']."' data-apikey='".$result['oxi_apikey']."' href='#'>".$local."</a></li>";
 
And your Jquery code:
 
$(function(){
    $('.clsPostData').click(function(e){
          e.preventDefault();
          var objPost = {};
          objPost.api = $(this).data('apikey');
          objPost.sensor = $(this).data('sensorid');
          $.ajax({
             url: 'getData.php',
             type: 'post',
             data: objPost
          }).done(function(responseFromPhp){
             //Do something with the response, like
             alert(responseFromPhp.message);
          });
    });
});
 
Your getData.php script:
 
<?php
   $apikey = $_POST["api"];
   $sensorid = $_POST["sensor"];

   $response["message"] = "Grettings from php, we receive your sensorid: ".$sensorid;
   echo json_encode($response);
?>
