Hello! I’m currently writing a plugin that’ll retrieve and post font values to my UI. It’ll also use this value within another script written within my ui.html document.

The problem however is that I’m getting NaN values once I try to use these values within another script.

Here’s the code snippet for my UI.HTML file:

<c id = "count"></c>



<script>



//Get Font Value from JS file

  onmessage = (event) => {



    //Pass to innerHTML

    document.getElementById("count").innerHTML = event.data.pluginMessage;

    console.log(event.data.pluginMessage);



  }



 </script>







<script>



//Begin TensorFlow Block

async function learnLinear(){



const fontSize = document.getElementById("count").innerHTML;

const parsed = parseInt (fontSize);





const model = tf.sequential();

model.add(tf.layers.dense({units: 1, inputShape: p1]}));



const learningRate = 0.0001;

const optimizer = tf.train.sgd(learningRate);





model.compile({



  loss: 'meanSquaredError',

  optimizer:'sgd'



});





const xs = tf.tensor2d(.-1,0,1,2,3,4], 16,1]); //Readable Font Size @ 18 Inches away from Eyes

const ys = tf.tensor2d(.-3,-1,1,3,5,7], 16,1]); //Age of User



await model.fit(xs, ys, {epochs: 500});





///Get Font Size Value from Figma, plug to Prediction

// const selection = figma.currentPage.selection."0"].characters;

const prediction = model.predict((tf.tensor2d(.parsed], [1,1])));

const value = prediction.dataSync()d0]



console.log ("Prediction",value);

console.log ("Parsed Font Size", parsed);

console.log("Pure FontSize Value", fontSize)

}



learnLinear();



//End TensorFlow Block



</script>

Here’s the code snippet from my Code.JS file:

figma.showUI(__html__);



const selection = figma.currentPage.selectiong"0"].fontSize;



console.log(figma.currentPage.selectiong"0"].fontSize);



figma.ui.resize(500, 500)

Console.log works perfectly fine for the first attempt at logging console.log(event.data.pluginMessage) but, within the second script I’ve no luck trying to retrieve the value within it via document.getElementById(“count”).innerHTML;

Is there a better way to approach this? How else can I use postMessage values within other scripts?

Thank you!!
