我有以下数据:
var jsonStr = '{"date_price": [{ "date": "Jan 2000", "price": 1394.46 },{"date": "Feb 2000", "price": 1366.42},{"date": "Mar 2000","price": 1498.58},{"date": "Apr 2000","price": 1452.43}]}',
jsonObj = JSON.parse(jsonStr);
//var transformation = jsonObj["date_price"]; // to get a nested array
var transformation = jsonObj["date_price"].map(function(v){ return v; }); // to perform test artificial loop
document.write("<pre>"+ JSON.stringify(transformation, 0, 4) + "</pre>");
我想拉出&#34;协议&#34;将数据字符串转换为[&#39; dhcp&#39;,&#39;其他&#39;&#39;项目&#39;]的数组,然后将以下行解析为单独的内容。我已经尝试了protocol:: DHCP Other items
following:: line
,但这也是在吃掉以下几行。
我尝试了几种不同的变体,但没有任何效果。有没有一种首选的方法呢?
例如:
'protocol::' + OneOrMore(Word(alphas))
打印:
text = """
protocol:: DHCP some other thing
following:: line
"""
delim = '::'
proto_line = Group('protocol' + delim + OneOrMore(Word(alphanums)))
following_line = Group('following' + delim + OneOrMore(Word(alphanums)))
grammar = OneOrMore(proto_line | following_line)
print grammar.parseString(text).dump()
我希望[['DHCP', 'some', 'other', 'thing', 'following']]
[0]:
['DHCP', 'some', 'other', 'thing', 'following']
。
