嵌套的JSON对象 [英] Nested JSON object
问题描述
我对这个JSON对象非常陌生.所以我需要你们的一些帮助.我必须创建一个JSON对象，并且该对象有两个孩子.一个孩子有几个孩子.如果我的问题令人困惑，请参考下图.它类似于嵌套列表.
例子:
PRODUCT_LIST
I am very much new to this JSON objects. So I need some helps from you guys. I have to create a JSON object and that object has two children. One child has some children. If my question is confusing just refer the following diagram. It is similar to nested lists.
Example:
PRODUCT_LIST
<ul>
<li>CATEGORY_ID - A</li>
<li>PRODUCT_DETAILS
<ul>
<li>PRODUCT_ID - A.1</li>
<li>PRODUCT_NAME - AAAA1111</li>
<li>UNIT_COST - 0.1</li>
</ul>
</li>
<li>CATEGORY_ID - B</li>
<li>PRODUCT_DETAILS
<ul>
<li>PRODUCT_ID - B.1</li>
<li>PRODUCT_NAME - BBBBB1111</li>
<li>UNIT_COST - 0.2</li>
</ul>
</li>
</ul>
我尝试这样做，但是出现JavaScript错误.任何人都可以帮助为上述图表创建JSON. 注意:一个类别具有多个产品详细信息.这意味着PRODUCT_ID，PRODUCT_NAME和UNIT_COST将针对特定的CATEGORY_ID重复多次.
I tried to do but got JavaScript errors. Can any one please help to create JSON for the above mentioned diagram. Note: One Category has more than one product details. It means PRODUCT_ID, PRODUCT_NAME and UNIT_COST will be repeating to more than one time for a particular CATEGORY_ID.
我尝试过的JavaScript代码
The JavaScript code I have tried
var product = '{"products_list":' +
'[' +
'{' +
'{"category_id":"A"},' +
'{"product_details":' +
'[' +
'{"product_id":"A.1","product_name":"AAAA1111", "unit_cost":"A1"},' +
'{"product_id":"A.2","product_name":"AAAA2222", "unit_cost":"A2"},' +
'{"product_id":"A.3","product_name":"AAAA3333", "unit_cost":"A3"},' +
'{"product_id":"A.4","product_name":"AAAA4444", "unit_cost":"A4"},' +
'{"product_id":"A.5","product_name":"AAAA5555", "unit_cost":"A5"},' +
'{"product_id":"A.6","product_name":"AAAA6666", "unit_cost":"A6"},' +
'{"product_id":"A.7","product_name":"AAAA7777", "unit_cost":"A7"},' +
'{"product_id":"A.8","product_name":"AAAA8888", "unit_cost":"A8"},' +
'{"product_id":"A.9","product_name":"AAAA9999", "unit_cost":"A9"},' +
'{"product_id":"A.0","product_name":"AAAA0000", "unit_cost":"A0"}' +
']' +
'}' +
'},' +
'{' +
'{"category_id":"A"},' +
'{"product_details":' +
'[' +
'{"product_id":"A.1","product_name":"AAAA1111", "unit_cost":"A1"},' +
'{"product_id":"A.2","product_name":"AAAA2222", "unit_cost":"A2"},' +
'{"product_id":"A.3","product_name":"AAAA3333", "unit_cost":"A3"},' +
'{"product_id":"A.4","product_name":"AAAA4444", "unit_cost":"A4"},' +
'{"product_id":"A.5","product_name":"AAAA5555", "unit_cost":"A5"},' +
'{"product_id":"A.6","product_name":"AAAA6666", "unit_cost":"A6"},' +
'{"product_id":"A.7","product_name":"AAAA7777", "unit_cost":"A7"},' +
'{"product_id":"A.8","product_name":"AAAA8888", "unit_cost":"A8"},' +
'{"product_id":"A.9","product_name":"AAAA9999", "unit_cost":"A9"},' +
'{"product_id":"A.0","product_name":"AAAA0000", "unit_cost":"A0"}' +

推荐答案
使用HTML树，您将获得PRODUCT_LIST的后续JSON表示形式:
Using the HTML tree, you will get the followin JSON representation for the PRODUCT_LIST:
[
{
"CATEGORY_ID":"A",
"PRODUCT_DETAILS":[
{
"PRODUCT_ID":"A.1",
"PRODUCT_NAME":"AAAA1111",
"UNIT_COST":0.1
}
]
},
{
"CATEGORY_ID":"B",
"PRODUCT_DETAILS":[
{
"PRODUCT_ID":"B.1",
"PRODUCT_NAME":"BBBBB1111",
"UNIT_COST":0.2
}
]
}
]
但是，您的JavaScript会生成几乎有效的JSON string ，该字符串已分配给product变量.您可以在其上使用 JSON.parse() ，但这太复杂了.由于 JavaScriptObjectNotation 是Java语言
However, your JavaScript produces a nearly valid JSON string, which is assigned to the product variable. You could use JSON.parse() on it, but that's too complicated. As the JavaScriptObjectNotation is a subset of the Javascript object literal syntax, you should directly assign the object.
在JSON中，类别对象周围的括号过多.您可以检查例如与 http://jsonformatter.curiousconcept.com/.更正的脚本:
In your JSON, you have some braces too much around the category objects. You can check that e.g. with http://jsonformatter.curiousconcept.com/. Corrected script:
var product = {
"products_list":[
{
"category_id":"A",
"product_details":[
{
"product_id":"A.1",
"product_name":"AAAA1111",
"unit_cost":"A1"
},
{
"product_id":"A.2",
"product_name":"AAAA2222",
"unit_cost":"A2"
},
{
"product_id":"A.3",
"product_name":"AAAA3333",
"unit_cost":"A3"
},
{
"product_id":"A.4",
"product_name":"AAAA4444",
"unit_cost":"A4"
},
{
"product_id":"A.5",
"product_name":"AAAA5555",
"unit_cost":"A5"
},
{
"product_id":"A.6",
"product_name":"AAAA6666",
"unit_cost":"A6"
},
{
"product_id":"A.7",
"product_name":"AAAA7777",
"unit_cost":"A7"
},
{
"product_id":"A.8",
"product_name":"AAAA8888",
"unit_cost":"A8"
},
{
"product_id":"A.9",
"product_name":"AAAA9999",
"unit_cost":"A9"
},
{
"product_id":"A.0",
"product_name":"AAAA0000",
"unit_cost":"A0"
}
]
},
{
"category_id":"A",
"product_details":[
