Sharing an automator variable with javascript

Is there a way for me to access the selected text in my automator workflow? When using the "Run bash action", I have the convenient option of "pass input as arguments". However, with the "Run JavaScript" action, this isn't available.

How can I effectively pass clipboard data (text) to my JS function named sum_letters?

Link to My Automator workflow

Answer №1

To Execute JavaScript Code in Automator, you must define a function called run() that is invoked during initialization. This function is where you will write your main code implementations, as shown below:

function run(input, parameters) {
    // Your script goes here
    return input;
}

The run() function takes two arguments, with the input argument being of particular interest. It holds any data passed from the preceding action in the workflow, stored as an array.

In your workflow, the content from the clipboard is passed through the Copy to Clipboard action and becomes the value stored in the input variable, represented by input[0].

You can then utilize this data by passing it to your custom function sum_letters().

This example illustrates how the structure would appear:

Run JavaScript:

function run(input, parameters) {
    var clipboardText = input[0];
    sum_letters(clipboardText);
    
    // Other lines of code
    
    return input[0];
}

function num_letters(k, d) {
    var i = '', e = [
        
        // ...etc...
    }
    
    function sum_letters(t) {
        
        // Lines of code
    }

and so forth. The run() function executes immediately when the workflow reaches the Run JavaScript action. Other functions like num_letters() and sum_letters() are executed only if explicitly called either from within run() or another function triggered by run().

The run() function completes upon encountering a return statement, which passes a specified value back to the Automator workflow for further processing.
