Functions Block

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

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. 

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. 

function () {

  return '';

};
