Question

我正在尝试从图表中导出数据集，其中一行应从第二个x轴点开始。即数据集看起来像

var dataset = [
  {           dept2:26, m:"Jan" },
  { dept1:30, dept2:38, m:"Feb" },
  { dept1:61, dept2:54, m:"Mar" },
  { dept1:65, dept2:67, m:"Apr" },
  { dept1:74, dept2:69, m:"May" },
  { dept1:74, dept2:69, m:"Jun" },
  { dept1:74, dept2:69, m:"Jul" }

];

但是，如果没有第一个值，Webix中的toExcel方法将不会导出列。我怎么能克服这个？

尝试以这种方式定义输出：

$doc = new DOMDocument;

$doc->preserveWhiteSpace = false;

$doc->strictErrorChecking = false;
$doc->recover = true;

$doc->loadHTMLFile('test.php?u=user1&type=test');

$xpath = new DOMXPath($doc);

$query = "//div[@id='test']";

$entries = $xpath->query($query);
var_dump($entries->item(0)->textContent);
