javascript - 将 JSON 数据从 ORACLE 获取到 Jquery Datatables

Question

我正在尝试将 JSON 数据放入我的数据表中，但不知何故它不起作用。请帮助我，

<script>
    $.getJSON('../vendor/process/process_vendor.php', function(response) {
        $('#vendorlist').DataTable({
          processing: true,
          data: response.data,
          columns: [
            { data: "PO_NO"}
          ]
        });
        window.someGlobalOrWhatever = response.balance;
      });
</script>

这是 process_vendor.php

$sql = oci_parse($conn, "SELECT VPI.PO_NO FROM VW_PO_INFO@WENFINANCE_WENLOGINV_LINK VPI WHERE VPI.PROJECT_NO LIKE '%' AND VPI.PROJECT_NAME LIKE '%'");
$errExc = oci_execute($sql);

if (!$errExc){
    $e = oci_error($sql);
        print htmlentities($e['message']);
        print "\n<pre>\n";
        print htmlentities($e['sqltext']);
        printf("\n%".($e['offset']+1)."s", "^");
        print  "\n</pre>\n";
} else {

    $res = array();
    while ($row = oci_fetch_assoc($sql)){
        $res[] = $row;
    } 
    $listPO = json_encode($res, JSON_PRETTY_PRINT);

    print_r($listPO);

    oci_free_statement($sql); // FREE THE STATEMENT
    oci_close($conn); // CLOSE CONNECTION, NEED TO REOPEN
}

和 JSON 数据:

[
  { "PO_NO": "0928-57\/WEN\/15" },
  { "PO_NO": "0928-57\/WEN\/15" },
  { "PO_NO": "0923-59\/WEN\/15" },
  { "PO_NO": "0916-57\/WEN\/15" },
  { "PO_NO": "1002-06\/WEN\/15" }
]

由于您的响应中没有关键数据，请尝试使用:do console.log(response) 检查您是否已正确收到数据。

 var responseObj = JSON.parse(response);

然后使用 responseObj 获取数据。

data: responseObj,

原始数据示例:

var response=[ { "PO_NO": "0928-57/WEN/15" }, { "PO_NO": "0928-57/WEN/15" }, { "PO_NO": "0923-59/WEN/15" }, { "PO_NO": "0916-57/WEN/15" }, { "PO_NO": "1002-06/WEN/15" }];

$('#vendorlist').DataTable({
          processing: true,
          data: response,
          columns: [
            { data: "PO_NO"}
          ]
        });
