[英]PHP and javascript: pass new Date as json

我利用谷歌圖表。在DataTable中我需要一個日期,例如,javascript代碼必須如下:
rows: [{c:[{v: 'Mike'}, {v: new Date(2008, 1, 28), f:'February 28, 2008'}]},
How can i pass the
我怎么能通過
new Date(2008, 1, 28)
as json object from php?
作為json對象從PHP?
I have done:
我已經做好了:
....
array('v' => "new Date($timeStamp)");
...
$output = json_encode($table);
but in the javascript i receive new Date(2008, 1, 28) as string and doesn't instantiate new date.
但在javascript中我收到新的日期(2008,1,28)作為字符串,並沒有實例化新的日期。
How can i instantiate a new Date()?
我如何實例化一個新的Date()?

You can do this one in you javascript:
你可以在你的javascript中執行此操作:
var date = eval("new Date(2008, 1, 28)"); // Here should paste the string that you receive.
That should eval it.
那應該評估它。

The JavaScript object you want to get to is not JSON, as JSON does not allow the new keyword, nor the call of a function, like Date().
您想要獲取的JavaScript對象不是JSON,因為JSON不允許使用new關鍵字,也不允許調用函數,如Date()。
What you could do, is move away from pure JSON, like this:
你能做什么,就是擺脫純粹的JSON,就像這樣:
<?
$timeStamp = time (); // UNIX epoch
$table = array(
array('v' => 31415926535), // some unique number, that does not occur elsewhere
);
$output = json_encode($table);
// Alter JSON, and now you cannot call it JSON anymore:
$output = str_replace($table[0]['v'], "new Date($timeStamp)", $output);
?>
<script>
var table = {
...
rows: <?= $output ?>,
...
};
...
</script>
Make sure the $timeStamp is either a number representing a UNIX epoch (like example abopve), or a string, well-formatted for JavaScript to interpret as a date. In the latter case you will need to wrap $timeStamp in single quotes.
確保$ timeStamp是代表UNIX紀元的數字(例如abopve),或者是一個字符串,格式良好,可以將JavaScript解釋為日期。在后一種情況下,您需要將$ timeStamp包裝在單引號中。
