摆脱JSON中的双引号

Question

我需要摆脱我的JSON字符串中的双引号，这就是我如何形成一个数组然后将其转换为JSON

$dinnerDetails = array();
foreach ($dinners as $dinner) {
    $dinnerDetails[] = array(
        "title" => $dinner->getName(),
        "data" => $dinner->getDate()
    );
}

$dinnerDetails = json_encode($dinnerDetails);

当我转储$dinnerDetails时，在我的视图中，我看到以下内容

string '[
    {
        "title": "Formal Dinner",
        "data": "Tue Apr 05 2016 05:00:00 GMT+0500 (PKT)"
    },
    {
        "title": "Formal Dinner",
        "data": "Tue Apr 05 2016 05:00:00 GMT+0500 (PKT)"
    },
    {
        "title": "Black Tie",
        "data": "Wed Apr 13 2016 05:00:00 GMT+0500 (PKT)"
    },
    {
        "title": "Formal Dinner",
        "data": "Fri Apr 08 2016 05:00:00 GMT+0500 (PKT)"
    }
]

当我将此分配给JS变量时，这是在源

中看到它的方式

var dinners = [
    {
        "title": "Formal Dinner",
        "data": "Tue Apr 05 2016 05:00:00 GMT+0500 (PKT)"
    },
    {
        "title": "Formal Dinner",
        "data": "Tue Apr 05 2016 05:00:00 GMT+0500 (PKT)"
    },
    {
        "title": "Black Tie",
        "data": "Wed Apr 13 2016 05:00:00 GMT+0500 (PKT)"
    },
    {
        "title": "Formal Dinner",
        "data": "Fri Apr 08 2016 05:00:00 GMT+0500 (PKT)"
    },
    {
        "title": "Formal Dinner",
        "data": "Sat Apr 16 2016 05:00:00 GMT+0500 (PKT)"
    },
    {
        "title": "Formal Dinner",
        "data": "Mon Mar 28 2016 05:00:00 GMT+0500 (PKT)"
    }
];

我正在使用Symfony框架，这就是我将$dinnerDetails传递给视图

的方式

return $this->render('AppBundle:admin/college:edit.html.twig', array(
    'dinners' => $dinnerDetails
));

然后在内部树枝中我将像这样分配给js变量

var dinner = jQuery.parseJSON(dinners);

在JS中我甚至尝试过JSON.parse(dinners.replace(""",'"'));，但这没有帮助。

我正在寻找的输出是这样的

[
                    {
                        title: "All Day Event",
                        date: "Fri Apr 08 2016 05:00:00 GMT+0500",
                    },
                    {
                        title: "Long Event",
                        date: "Fri Apr 08 2016 05:00:00 GMT+0500",
                    },
]

我真的很感激这里的帮助。

Answer 1

在您的控制器或php文件中使用以下代码。

<?php
$arrDinnerDetails = array();
foreach ($dinners as $dinner)
{
    $arrDinnerDetails[] = array(
        "title" => $dinner->getName(),
        "data"  => $dinner->getDate()
    );
}
return $this->render('AppBundle:admin/college:edit.html.twig', array(
            'arrDinnerDetails' => $arrDinnerDetails
        ));
?>

在您的视图文件中，使用以下代码。

<script>
    var strJsonDinner = JSON.stringify('<?php echo json_encode($arrDinnerDetails); ?>');
</script>

Answer 2

尝试模板中的raw-filter。像这样：

{{ dinners|raw }}

第二。您已将PHP-Object序列化为JSON字符串。
如果将此字符串粘贴到脚本块中，则此字符串将解释为为JS。
它现在是JS代码，不再是字符串了。你不必解析它;实际上你无法解析它。

<script> var dinner = {{ dinners|raw }}; </script>
