Advanced Component

The Advanced component consists of blocks that perform specific actions.

Try Catch Finally

The Try statement lets you test a block of statements for errors.
The Catch statement lets you handle the error. The catch statement has an inbuilt error variable that can be used for diagnosing.
The Finally statement lets you execute code, after trying and catching, regardless of the result.

Regular Expression

Regular Expressions are patterns useful for efficient text processing. A regular expression can be matched, tested, or executed by specifying the expression path and input values.

Choose the type of Text matching from the dropdown list(match, test, exec) Regex format as a variable or Text - input-1, Input data as a variable or Text - input-2	For match: returns matching text else null, For test: returns true or false, based on the result, For exec: returns the found text as an object else null.		`__er.regularExpression("test", /expression/g, 'input');`

Choose the type of Text matching from the dropdown list(match, test, exec)

Regex format as a variable or Text - input-1,

Input data as a variable or Text - input-2

For match: returns matching text else null,

For test: returns true or false, based on the result,

For exec: returns the found text as an object else null.

__er.regularExpression("test", /expression/g, 'input');

Set Timeout

This block calls a function or any code block after a number of milliseconds.

Input Output Block Layout Generated Code

Time in milliseconds as a variable or number - input-1 Function or code as a statement block.	Returns a number, representing the ID value of the timer that is set.		`setTimeout(async function(){}, 0);`

Time in milliseconds as a variable or number - input-1

Function or code as a statement block.

Returns a number, representing the ID value of the timer that is set.

setTimeout(async function(){}, 0);

Set Interval

This block executes any code block repeatedly for the specified interval time(in milliseconds).

Input Output Block Layout Generated Code

Input	Output	Block Layout	Generated Code
Time in milliseconds as a variable or number - input-1, Function or code as a statement block.	NA		`setInterval(async function(){}, 10);`

Time in milliseconds as a variable or number - input-1,

Function or code as a statement block.

setInterval(async function(){}, 10);

Set Timeout

This block calls a function or any code block after a number of milliseconds. This block can be set to a variable(using a set block) and the variable can be used to cancel the timeout period.

Time in milliseconds as a variable or number - input-1 Function or code as a statement block.	Returns a number, representing the ID value of the timer that is set.		`var item; async function er_1674710886_click(e,obj,index){ item = setTimeout(async function(){}, 0); }`

Time in milliseconds as a variable or number - input-1

Function or code as a statement block.

Returns a number, representing the ID value of the timer that is set.

var item;


async function er_1674710886_click(e,obj,index){
   item = setTimeout(async function(){}, 0);

}

Set Interval

This block calls a function or any code block at specified intervals(in milliseconds). This action block can be set to a variable(using a set block) and the variable can be used to cancel the interval period.

Input Output Block Layout Generated Code

Input	Output	Block Layout	Generated Code
Time in milliseconds as a variable or number - input-1, Function or code as a statement block.	Returns an interval object		`var item; async function er_1674710886_click(e,obj,index){ item = setInterval(async function(){}, 10); }`

Time in milliseconds as a variable or number - input-1,

Function or code as a statement block.

Returns an interval object

var item;


async function er_1674710886_click(e,obj,index){
   item = setInterval(async function(){}, 10);

}

Clear Interval

The Clear Interval block clears a timer set with the setInterval block.

Input	Output	Block Layout	Generated Code
The ID value of the timer as variable or number.	Clears a timer set with the set Interval block using interval id.		`clearInterval();`

Clear Timeout

The Clear Timeout block clears a timer set with the Set Timeout block.

Input	Output	Block Layout	Generated Code
The ID value of the timer as variable or number.	Clears a timer set with the set timeout block using timeout id.		`clearTimeout();`

JSON Parser

The JSON Parse String block is used to parse a JSON string which is written in a JSON format and it returns a JavaScript object.

Input	Output	Block Layout	Generated Code
JSON value as variable or Text.	Returns JSON Object corresponding input text JSON.		`__er.parseJSON('{}');`

JSON Stringify

The JSON Stringify block takes in a variable or object as an input and converts it into an equivalent string.

Input	Output	Block Layout	Generated Code
JSON Object as variable or Object value.	Returns Text JSON corresponding to the input JSON Object.		`__er.JSONStringify()`
