Trending sort

Trending sort is based off of the default sorting method — by highest score — but it boosts votes that have happened recently, helping to surface more up-to-date answers.

It falls back to sorting by highest score if no posts are trending.

I made it that way:

to convert pluginArrayArg (which is pure javascript array) into JSON array:

Wow, seems it got a lot easier nowadays. 3 ways you can do it:

One other way could be this:

I decided to use the json2 library and I got an error about “cyclic data structures”.

I got it solved by telling json2 how to convert my complex object. Not only it works now but also I have included only the fields I need. Here is how I did it:

Or try defining the array as an object. (var cars = <>😉 Then there is no need to convert to json. This might not be practical in your example but worked well for me.

The only way I converted my array into json is

I think this is the best and cleanest answer.

Shortest

To generate valid json from array of integers use

for more general arrays use JSON.stringify(cars) (for object with circular references use this)

If you have only 1 object like the one you asked, the following will work.

You can convert an array to JSON using the Object.assign function. The main issue that I hit with that is that Javascript arrays have a zero based integer key, which in turn allows to access the data in the array.

When you convert the array to JSON, you get

JSON objects on the contrary usually contain arbitrary keys, such as:

Happily, you can create a list of items, which works pretty much as an array and then use Object.assign as if it was an array, then convert the output to a JSON object

The advantage of working with item lists is that you don’t have to deal with the JSON data as a string or quotes, commas etc. You can instead just manage the item object filling data in or removing it. When you are done you just convert the item variable to a JSON object and do whatever you need to do with it.

If you’re really defining that string directly in code, just use an array literal instead:

If it’s not that, please edit more information into your question, like where is the string coming from, and what does it look like exactly.

To parse it, you can use

and then access using

Note that this is assuming the JSON is stored as a string to begin with and you are getting it from somewhere in that format. If you are actually just trying to create an array and access its elements, you should use an array literal as @bfavaretto answered.

If you’re using jQuery just use:

It’s exactly what you’re looking for

Your question is slightly confusing. Javascript objects in serialized, string form are in JSON. Your string looks like it wants to be JSON. If it were JSON, you could JSON.parse() it into an object. If you have a Javascript object, you can JSON.stringify() it into a string. You may need the json2.js library, depending on your browser.

JSON is a data-interchange format primarily intended for transmission of data between systems. Nonetheless, I interpreted your question as follows:

If this is the case, then @bfavaretto is correct in that what you really want is an array literal whose elements are objects. You can then access each individual object by index and any properties of that object by specifying the property name.

Shouldn’t it be something like this?

Your required format is invalid. I think you are looking for something like this

For this code will be like as below

Please check following code: This will make the proper formatting:

It will return output like:

This makes a proper json, which I think you need! Do let me know, if I am wrong somewhere.

If the array keys in your PHP array are not consecutive numbers, json_encode() must make the other construct an object since JavaScript arrays are always consecutively numerically indexed.

Use array_values() on the outer structure in PHP to discard the original array keys and replace them with zero-based consecutive numbering:

Example:

json_encode() function will help you to encode array to JSON in php.

if you will use just json_encode function directly without any specific option, it will return an array. Like mention above question

Since you are trying to convert Array to JSON, Then I would suggest to use JSON_FORCE_OBJECT as additional option(parameters) in json_encode, Like below

How to convert automatically list of objects to JSONArray with Gson library in java?

Lets say I have following list of custom object: ArrayList where GroupItem is some class that has int and String variables.

My project is Android with Cordova that has API based on org.Json.JSONArray

ANd I thought to write some generic way to convert instances to JSONArray / JSONObject

This way is worked for me:

Convert all list to String.

Create JSONArray from String:

The org.json based classes included in Android don’t have any features related to converting Java POJOs to/from JSON.

If you have a list of some class ( List ) and you absolutely need to convert that to a org.json.JSONArray you have two choices:

A) Use Gson or Jackson to convert to JSON, then parse that JSON into a JSONArray :

B) Write code to create the JSONArray and the JSONObject s it will contain from your Java objects:
