Question

我能够使用JSON.parse解析单个对象。

var testing = '{"appid": "730", "contextid": "2", "amount": "1", "assetid": "2883267603"}';
var itemsObject = JSON.parse(testing);

但是当我尝试用多个对象解析变量时：

var testing = '{"appid": "730", "contextid": "2", "amount": "1", "assetid": "2883267603"}, {"appid": "730", "contextid": "2", "amount": "1", "assetid": "3084880561"}'; 
var itemsObject = JSON.parse(testing);

我收到以下错误：

SyntaxError: Unexpected token ,

Answer 1

你需要制作一个对象数组

data, target = load_data(minibatch_index)  # load_data returns typical numpy.ndarrays for a given minibatch

data_shared = theano.shared(np.asarray(data, dtype=theano.config.floatX), borrow=True)
target_shared = T.cast(theano.shared(np.asarray(target, dtype=theano.config.floatX), borrow=True), 'int32')

cost_ij = train_model(data_shared ,target_shared )

Answer 2

因为testing现在是一个（如你所说 - 多个）对象的数组，你应该在它们周围加上方括号来表示：

var testing = '[{"appid": "730", "contextid": "2", "amount": "1", "assetid": "2883267603"}, {"appid": "730", "contextid": "2", "amount": "1", "assetid": "3084880561"}]';

试试这个： var testing =＆＃39; [{＆＃34; appid＆＃34;：＆＃34; 730＆＃34;，＆＃34; contextid＆＃34;：＆＃34; 2＆＃34;，＆＃34;金额＆＃34;：＆＃34; 1＆＃34;，＆＃34; assetid＆＃34;：＆＃34; 2883267603＆＃34;}，{＆＃34; appid＆＃34;：＆＃34; 730＆＃34; ，＆＃34; contextid＆＃34;：＆＃34; 2＆＃34;，＆＃34;金额＆＃34;：＆＃34; 1＆＃34;，＆＃34; assetid＆＃34;：＆＃34; 3084880561＆＃34;}]＆＃39 ;; var itemsObject = JSON.parse（testing）;
