第一个jquery / ajax测试不起作用

我尝试在我的网络项目中更多地使用jQuery / Ajax,作为我做过的测试: HTML代码

<div id="main_content"></div>
<div class="panel panel-primary">
    <div class="panel-heading">API Credits Left.</div>
    <div class="panel-body">
        <form id="frmAjax" action="<?php echo $_SERVER['PHP_SELF'] ?>" method="post" class="form-horizontal container-fluid" role="form">
            <div class="row form-group">
                <div class="col-sm-12 text-right">
                    <button type="submit" name="submit" class="btn btn-default">Check the API credits...</button>
                </div>
            </div>
        </form>
    </div>
    <div class="panel-footer"><b>DomDetailer</b> & <b>SeoKicks</b> Api credits left.</div>
</div>

脚本

$(function() {
$(document).ready(function(){
    $('#frmAjax').submit(function() {
      $("#main_content").load('ajax-credits.php');
    });
  });
});

ajax-credits.php 内容:

<?php
  echo "Loading...";
  // http://site1.com/api/checkBalance.php?apikey=QRUE8VTQMD5Fj6&app=
  $json1 = file_get_contents('http://site1.net/api/checkBalance.php?apikey=QRUE8VTQMD5F6&app='); 
  $data1 = json_decode($json1, true);
  $valu1 = $data1[1];
  // seokicks 
  $json2 = file_get_contents('http://www.site2.net/V1/inlinkData?appid=p2hFacSWU0&output=json&details=api_credits'); 
  $data2 = json_decode($json2);
  $valu2 = $data2->Overview->credits->available;
  // display
  stdmsg("Site 1 has <b>".$valu1."</b> credits left and Site 2 has <b>".$valu2."</b> credits left.");
?>

非常基本的代码(或者我认为)任何人都可以看到我做错了什么? div中没有​​显示任何内容,有什么问题吗?

1 个答案:

答案 0 :(得分:2)

尝试删除echo "Loading";并替换

    stdmsg("Site 1 has <b>".$valu1."</b> credits left and Site 2 has <b>".$valu2."</b> credits left."); 

通过

    echo "<p>Site 1 has <b>".$valu1."</b> credits left and Site 2 has <b>".$valu2."</b> credits left.</p>";

(无论你在jQuery AJAX函数调用的PHP脚本中回应什么,都会被发送回AJAX函数,因此这将被加载到你的HTML div中。)
