Description
Converts any given struct, array or primitive parameter to a JSON string. By default, the JSON resulted from the conversion also contains the empty fields (in the case of structures for example) with null values.If you want these to be excepted from the conversion, you will have to set the convertEmptyFields flag to false.
Parameters
Return Type
String
Example
Colors JSON Example Code
You can look at this function as the preparatory one for the integration with other systems. You build your data structure first and then convert your struct to json to be sent to an external system. This script demonstrates the process of using structs and/or arrays to create JSON output.
//Step 1 - define the structs/arrays
struct code {
number [] rgba;
string hex;
}
struct color {
string color;
string category;
string type;
code code;
}
struct colors {
color [] colors;
}
//Step 2 - add data to the structs
color red;
red.color = "red";
red.category = "hue";
red.type = "primary";
red.code.rgba = {255, 0, 0, 1};
red.code.hex = "#FF0";
color yellow;
yellow.color = "yellow";
yellow.category = "hue";
yellow.type = "primary";
yellow.code.rgba = {255, 255, 0, 1};
yellow.code.hex = "#FF0";
color blue;
blue.color = "blue";
blue.category = "hue";
blue.type = "primary";
blue.code.rgba = {0, 0, 255, 1};
blue.code.hex = "#00F";
color green;
green.color = "green";
green.category = "hue";
green.type = "primary";
green.code.rgba = {0, 255, 0, 1};
green.code.hex = "#0F0";
colors colors;
colors.colors += red;
colors.colors += yellow;
colors.colors += green;
colors.colors += blue;
//Step 3 - create the JSON
return toJson(colors);Resulting JSON:
{
"colors":[
{
"color":"red",
"category":"hue",
"type":"primary",
"code":{
"rgba":[255,0,0,1],
"hex":"#FF0"
}
},
{
"color":"yellow",
"category":"hue",
"type":"primary",
"code":{
"rgba":[255,255,0,1],
"hex":"#FF0"
}
},
{
"color":"green",
"category":"hue",
"type":"primary",
"code":{
"rgba":[0,255,0,1],
"hex":"#0F0"
}
},
{
"color":"blue",
"category":"hue",
"type":"primary",
"code":{
"rgba":[0,0,255,1],
"hex":"#00F"
}
}
]
