In the first script step we delete an element from the object. You can not only add elements, also you can delete elements from an array or an object. By using the " JSON.Clone" function, you get a new reference number for a JSON structure in memory that you can use for your next steps. you can us that, if you have a JSON part that you want use multiply times with a minimum of changes. The MBS JSON Functions can handle arbitrarily large numbers and avoid the rounding of 15 digits. For other datatypes you will finde convenient functions. If you use „JSON.CreateNumber“, you can create a number node that is encoded for JSON. a boolean node which value depends on a condition: You can also add variant JSON Nodes with certain types e.g. With „JSON.CreateStringArray“ you create a new array with any number of string values while „JSON.CreateStringArrayWithList“ takes the values from a list passed in one parameter. For example the functions „JSON.CreateDoubleArray“ and „JSON.CreateIntegerArray“ pass any number of parameters and create a new array with this values. There is the possibility to pass more than one value directly in the parameters. Here we parse the JSON, but don't return an error message, but just 0 for an error and 1 for okay. For that you have the „JSON.IsValid“ function. It is advisable, to check a JSON for errors and validate the JSON. But you should pay attention on the quotes that should’t be escape and change them back manually.
You can search for " and replace them with \" using our find bar, saving you some time.
#Xojo access array of arrays for mac
Some special tip for Mac users: The escaping in huge texts can take lots of time, because of that you can use the search and replace function that the MBS Plugin provides you for Mac. If you want to write a quote in FileMaker you must escape the quotes with a prefix backslash (\"), else you get an error. You can enter a JSON as a text and remove needles blankets with „JSON.Compact“ function.Īttention: Strings are in quotes in JSON. If you want to write a JSON by your own, you have different possibilities to do this. With the function „ JSON.Format“ in combination with „ JSON.Colorize“ you can format and color the JSON text to understand the data structure much easier.
If we get a JSON it is usually unformatted and the direct reading can be confusing for you as developer. The typical structure of a JSON you can see in the follow example: The elements of the array are in brackets: e.g. This elements can be objects or one of a forenamed datatypes. The value can have different datatypes: null, true and false, numbers (with a sequence of digests from 0-9, positiv and negativ numbers, decimal numbers and exponent E), strings, JSON objects or arrays. Objects are in curly brackets and can contain several elements separated by comma. A JSON text consists of objects written in brackets and arrays (lists). The Java Script Object Notation is a compact data format that is easy readable for humans. The MBS FileMaker Plugin supplies you with a lot of JSON functions, optimized for performance and usability.
It is a data format often used to transfer data in APIs over the Internet. JSON is a very popular data format, because it is easy readable for humans and can be easily parsed by software.
