Question

每次登录系统时都会出现此对话框，在使用开发环境运行时会一直弹出。

DataTables警告： table id = datTable - 无法重新初始化DataTable。

但每当我运行生产环境时，一切正常。我怎么能摆脱这个？

// controller

public function indexAction() {
    $em = $this->getDoctrine()->getManager();
    $po = $em->getRepository('MatrixEdiBundle:EdiTransactionDetail')->findDocs('850');

    return $this->render('MatrixEdiBundle:Matrix:index.html.twig', array('po' => $po));
}

// index.html.twig

{% extends 'layout.html.twig' %}
{# {% include 'MatrixEdiBundle:Matrix:header.html.twig'%} #}

Answer 1

<强>原因

错误Cannot reinitialise DataTable表示DataTable不会被$('#datTable').dataTable()多次初始化而不会被销毁。

<强>解

您只需在代码中运行$('#datTable').dataTable()一次，因此模板一定有问题。在StackOverflow上搜索确认了这一点，请参阅answer for "JavaScript loading twice in Symfony"。

您需要将包含JavaScript代码{% block javascripts %} ... {% endjavascripts %}的块移动到正文块{% block body %} ... {% endblock %}之外。

使用Symfony2和Twig时出现“无法重新初始化DataTable”的警告
