kandi X-RAY | jsonarray Summary
Go library for decoding very large or streaming JSON arrays. Many streaming JSON APIs give you newline-separated JSON. That's easy to parse, just keep calling json.Decoder.Decode. Sometimes, streaming APIs, and especially JSON databases, just return a very large JSON array as their result. This is not as easy to handle. jsonarray makes it easy. (If the large array isn't the outermost JSON object, that's still harder to get right. Ideas for API that can handle that are welcome.). Use the Go import path.

QUESTION
So when I have a JsonNode I can just ask if it's a JsonObject or a JsonArray and work with those. But when the node is an actual value, how do I know whether it's a string, number or boolean?
Of course I could just try and parse the value, but then a number transmitted in a string would become a number instead of a string which I'd like to avoid.
I'm using System.Text.Json with .NET 6.
...ANSWER
Answered 2022-Mar-23 at 13:33Each JsonProperty has two properties - Name and Value of Type JsonElement. JsonElement has an Enum property named ValueKind which can help you determine what of what data type your JSON value is.
You can get JsonProperties by calling .EnumerateObject() on your JsonElement. You can work with your Json document as a JsonElement instead of JsonObject.
QUESTION
I have a program where a user can set an event, with an start date, end date and the period of repetition the event shall repeat, weekly, monthly by date, monthly by weekday and yearly. After the user creates the event, it gets saved in the database and the event is displayed in a calendar on the main page of my program.
So far I've been able to devise the algorithms for repeating dates weekly, monthly by dates and yearly, but not monthly by weekday. By "monthly by weekday" I'm referring to an event that repeats every same weekday once a month, in the period the start date and end date occupies.
For example, an event that repeats the first Monday of every month between March 1st and November 1st, March 1st is the first Monday of March, so I would like to generate a date that is the first Monday of April, which is April 5th, and so on on every month between March and November.
The snippet below is my function for repeating dates monthly by dates, this is for events that repeat every 15th of any month between the start date and end date.

Answered 2021-Nov-29 at 01:36Could you just get the day of the week of the first of the month, then from that figure out how many days until the desired day of the week. Then add multiplies of 7 until you get the desired date.

I am trying to loops through a json response in CFML, and need to do one call to get the number of pages, then a call for each successive page, then loop through items to get my data. In doing so I have a nested loop that requires a nested variable. So, for example, my initial loop will result in:
...ANSWER
Answered 2022-Mar-08 at 01:07Since items is an array of structures, it's simpler and cleaner to use an "array" loop.
If some of the structure keys are optional, try using the safe navigation operator ?.. In the example below, it prevents an error from occurring when the code uses a non-existent key name like "lookMaNoErrors"?

Answered 2022-Jan-04 at 09:28Your join graph creates a cartesian product between the two "nested collections" ROLE and PERMISSION. You can't remove that cartesian product with GROUP BY alone, that works only if you join a single to-many relationship.
Instead, you can write subqueries like this (you already did this correctly for the ROLE_PERMISSION relationship):

...ANSWER
Answered 2021-Dec-17 at 16:59In general, you violated the Single Responsibility principal (SOLID), because your code do two different things together: parse a file and categorize items. You should split these responsibilities.
One of ways how you do this is to create classes that represents your data. Let's assume that these classes are Item, Category, Order and CategorizedItems. Order is a class that represents your source JSONObject and CategorizedItems - represents your result JSONArray.
In this case, you should firstly parse the file into these classes and only after that transform them into JSONArray.
Code sample:

Hello i have some problem with json filtration
when i print jsonArray without id (jsonArray) prints the object to me normally but when i add .id (jsonArray.id) its says undefined What am I doing wrong?
the object i gets with jsonArray and i want to print only 'id' of it
{id: 39497866969165, product_id: 6677529493581, title: '8', price: '181.50'}

Answered 2021-Nov-25 at 13:48It's because jsonArray here is a list and not a single object.
First check it's length to make sure there's atleast one object after the filter and log the first element via:

ANSWER
Answered 2021-Oct-18 at 15:50There is no array in the JSON document you have shown. "KAVAUSDT", "CFXUSDT", etc are not array elements, they are simply named object fields of the "data" object. If you need to loop through the child fields of the "data" object, you can use TJSONObject (not TJSONArray!) for that, eg:
