Article summary

Functions related blocks are explained below

Functions are a set of codes that can be called repeatedly for a particular operation.  The function is executed when something invokes it (calls it). In the EdgeReady Cloud, these functions are available as individual blocks. 


There are two types of functions: One that returns a value and one that does not return a value. 


In these blocks: 

  • Function parameters are listed inside the blocks in the function definition.
  • Function arguments are the values received by the function when it is invoked.
  • Inside the function, the arguments (the parameters) behave as local variables.

Create Function:

This block helps users create new functions. The functions can be created:  

  • Without Return Value
  • With Return Value
  • As a Global Function or local function

Input 

Output

Block Layout

Generated Code

Function Name Text,

 

Arguments Name text,

 

set as a global function checkbox,

 

allow statements checkbox,

 

Function statements.

 

Return for a function of any type.

This block will create a function definition depending upon input arguments and the choice of whether they are global.





var Name = function () {

}

window.Name = function (x, y) {

}


var Name2 = function () {

  return '';

}


Invoke Function:

Function invocation occurs when: 

  • When an event occurs (when a user clicks a button)
  • When it is invoked (called) from another code block
  • Automatically (self invoked)

In the EdgeReady Cloud, the function block is invoked:

  • With Return Value
  • Without Return Value
  • As a Global Function

Input

Block Layout

Generated Code

Function Name Text,

 

Arguments variable or any type value.

Call the function definition using name and arguments.



Name('', '');


Name2()


Function Definition with an input statement:

In this function definition, an input statement is provided. The input function is used to request the user to provide necessary input in a designated input field. The value is then returned as the result of the function that is stored in the declared variable.

Generated Code

Arguments variable or any type value,

 

Function statements.

 

Return for a function of any type.

Create a function definition with return and input statements that store to a variable or as a value.



function () {

};


Function Definition without a statement: 

In this function definition block, there is no input that is requested from the user. However, this function can return a value based on the nature of the action triggered and parameters defined to invoke the function. 

Input

Generated Code

Arguments variable or any type value,

 

Return for a function of any type.

Create a simple function definition with return only that store to a variable or as value.

function () {

  return '';

};
