Variables in JavaScript Node
Handling local variables within JavaScript automation logic.
With the JavaScript node, it is possible to manage simple variables.
Сreate Variables
To create a variable using the JavaScript node, follow these steps:
1. Add a JavaScript node to the scenario with the following code:
export default async function run({ execution_id, input, data, store }) { // Set Vars directly from JS // String are available const v_str = await store.setVariable("VarFromJs", "var value"); return { } }
This code represents an asynchronous function run. This function is designed to be executed in a web automation scenario and utilizes objects execution_id, input, data, and store.
The function defines the variable VarFromJs and saves it using the store.setVariable method. This variable can only be used within the current scenario.
2. Run the JavaScript node once and wait for its execution;
3. Check for the existence of the new variable when populating parameters for any other node.
Getting Variables
To get a variable using the JavaScript node, follow these steps:
1. Add a JavaScript node to the scenario with the following code:
export default async function run({ execution_id, input, data, store }) { // Get Vars const res_v_str = await store.getVariable("VarFromJs") return { res_v_str } }
This code represents an asynchronous function run. This function is designed to be executed in a web automation scenario and utilizes objects execution_id, input, data, and store.
The code extracts the values of the variable using the store.getVariable method. This method returns the value of a previously set variable.
2. Run the JavaScript node once and wait for its execution;
3. Check the output data of the JavaScript node for the variable values:
