1.JSON 不能儲存 Date 對象。2.如果你需要儲存 Date 對象，需要將其轉換為字串。3.之後再將字串轉換為 Date 對象。舉例：
1 <!DOCTYPE html> 2 <html> 3 <head> 4 <meta charset="utf-8"> 5 <title>菜鳥教程(runoob.com)</title> 6 </head> 7 <body> 8 9 <h2>將字串轉換為 Date 對象。</h2>10 11 <p id="demo"></p>12 13 <script>14 15 var text = ‘{ "name":"Runoob", "initDate":"2013-12-14", "site":"www.runoob.com"}‘;16 var obj = JSON.parse(text);17 obj.initDate = new Date(obj.initDate);18 19 document.getElementById("demo").innerHTML = obj.name + "建立日期: " + obj.initDate;20 21 </script>22 23 </body>24 </html>
結果為：
將字串轉換為 Date 對象。Runoob建立日期: Sat Dec 14 2013 08:00:00 GMT+0800 (中國標準時間)
另一種方式：可以啟用 JSON.parse 的第二個參數 reviver，一個轉換結果的函數，對象的每個成員調用此函數。
<!DOCTYPE html><html><head><meta charset="utf-8"><title>菜鳥教程(runoob.com)</title></head><body><h2>字串轉換為 Date 對象</h2><p id="demo"></p><script>var text = ‘{ "name":"Runoob", "initDate":"2013-12-14", "site":"www.runoob.com"}‘;var obj = JSON.parse(text, function (key, value) { if (key == "initDate") { return new Date(value); } else { return value;}});document.getElementById("demo").innerHTML = obj.name + "建立日期：" + obj.initDate;</script></body></html>
結果一樣.
