1. 起因：JSON.stringify方法轉換成的字串為JSON格式，屬性名帶有雙引號，input輸入框提交時報錯。原因待確認。
2.
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title></title> </head> <body> <script type="text/javascript"> Object.prototype.toString = function() { var str = '{' for(var tmp in this) { if(typeof this[tmp] === 'object') str += tmp + ':' + this[tmp] + ',' else str += tmp + ':"' + this[tmp] + '",' } return str + '}' } var o = { a: '1', b: { c: '1', d: { e: '1' } } } console.log(o) //"{a:"1",b:{c:"1",d:{e:"1",},},}" eval('var o2 = ' + o) console.log(o2) //"{a:"1",b:{c:"1",d:{e:"1",},},}" </script> </body> </html>
