$.post("someurl",{
"key1" : "value1","key2" : "value2","key2" : "value3","key2" : "value4","key3" : "value5"
});
,jQuery将发送请求
someurl?key1=value1&key2=value4&key3=value5
所有这一切,因为Javascript覆盖具有相同名称的属性. JSON对象是动态生成的,我不允许在其中使用数组.有人可以告诉我如何生成JSON对象dinamicaly和重复键？
我真的很感激你的帮助！
解决方法
An object structure is represented as a pair of curly brackets
surrounding zero or more name/value pairs (or members). A name is a
string. A single colon comes after each name,separating the name
from the value. A single comma separates a value from a following
name. The names within an object SHOULD be unique.
…应该说：
3. SHOULD. This word,or the adjective “RECOMMENDED”,mean that there
may exist valid reasons in particular circumstances to ignore a
particular item,but the full implications must be understood and
carefully weighed before choosing a different course.
那么是的,基本上你可以做到这一点,这是合法的,但这也是一个坏主意.不同的JSON解码器可能会以不同的方式处理这种情况和/或以不可取的方式.看看规范要求的解析器：
A JSON parser transforms a JSON text into another representation. A
JSON parser MUST accept all texts that conform to the JSON grammar.
A JSON parser MAY accept non-JSON forms or extensions.An implementation may set limits on the size of texts that it
accepts. An implementation may set limits on the maximum depth of
nesting. An implementation may set limits on the range of numbers.
An implementation may set limits on the length and character contents
of strings.
…但一个实现不一定要像这样的情况下处理.例如：
# Python 2.7
>>> import json
>>> json.JSONDecoder().decode('{"a": "b","a": "c"}')
`{u'a': u'c'}`
# Chrome 32
> JSON.parse('{"a": "b","a": "c"}')
Object {a: "c"}
…和其他实现可能合法地给你(以Python符号)：
>
{"a": "b"}
>
[("a","b"),("a","c")]
>
[("a",["b","c"])]
>
[]
>
42
>
"your JSON is bad and you should feel bad"
…或者只是好的老nasal daemons.字面上,JSON解析器在这里做的唯一的非法事情是引发异常.
在制作代码中最后一件事就是依靠奇怪的一面.所以你最后要做的就是行使你的名义上合法但实际上无用的JSON的权利.如果你想这样做,你必须手工创建你自己的抽象语法树,你自己的解析器,你自己的生成器,任何人谁可能想要消耗你的数据的生成器…
