Javascript 在单独的文件中与getJSON一起使用PHP数据时出现问题

javascript php jquery ajax

Javascript 在单独的文件中与getJSON一起使用PHP数据时出现问题,javascript,php,jquery,ajax,getjson,Javascript,Php,Jquery,Ajax,Getjson,我在wos.php中创建了一个数组，然后我使用jQuery在另一个文件data.php中使用它json\u encode和echo。由于某种原因，数据未被提取 这是在wos.php中创建的数组（$recordArray）的一个示例： Array ( [0] => Array ( [author1] => QIN, JUN-SHENG [citations] => 61

我在
wos.php
中创建了一个数组，然后我使用jQuery在另一个文件
data.php
中使用它
json\u encode
和
echo
。由于某种原因，数据未被提取

这是在
wos.php
中创建的数组（
$recordArray
）的一个示例：

Array
(
    [0] => Array
           (
               [author1] => QIN, JUN-SHENG
               [citations] => 61
           )
    [1] => Array
           (
               [author1] => KOHANE, DANIELS
               [citations] => 60
           )
    [2] ...etc...
这就是我执行
echo json\u encode（$recordArray）
后数据的样子：

所有这些看起来都是正确的格式。然后在
data.php
中使用该数据，并使用jQuery/D3将其显示在条形图中。下面是该代码的一个片段，它应该使用
getJSON
从
wos.php
读取数据：

<!DOCTYPE HTML>

        // this is just so I know it has reached this point
        console.log("Works to here...");

        $(document).ready(function() {

            $.getJSON('wos.php', function(data) {

            alert(data);

            ...code that uses data to with D3 to display a bar graph...

            }
