convert json to json schema

JSON Basics Simply put, JSON can convert a set of data represented in a JavaScript object into a string, which can then be easily passed between functions, or in an asynchronous application passing a string from a WEB client to a server-side program. The string looks a bit odd (see a couple of examples later), but JavaScript is easy to explain, and

name of the first entry in the programmers list, just use the following code in JavaScript: People.programmers[0].lastname; Note that the array index is zero-based. So, this line of code first accesses the data in the people variable, moves to the entry called programmers, moves to the first record ([0]), and finally accesses the value of the LastName key. The result is the string value "McLaughlin". Here are several examples of using the same variable. Copy Code code as follows:

JSON (JavaScriptObjectNotation) is a lightweight data exchange format. JSON uses a language-independent text format. These features make JSON an ideal Data Exchange Language, JSON (JavaScript Object Notation), a lightweight data exchange format. JSON uses a language-independ

: Var objs = [{id: 1, name: 'n' _ 1'}, {id: 2, name: 'n' _ 2'}];Alert (objs [0]. id );In this way, the object array objs is defined. It contains two objects and can be accessed using indexes. For example, objs [0] Will reference the first object. Here you may have thought about the format of the string returned by the server, but the string is a string after all, and we need to convert it to a variable that can be operated by JS. This uses the eval fu

. count = 10; // or obj ["count"] = 10} The modified JSON. 4. delete data in JSON Now we can delete the count data from JSON. The Code is as follows: function Delete() { delete obj.count; } Deleted JSON You can see that count has been deleted from the JSON
