Steps to generating a dynamic fabric canvas upon opening a new window

There seems to be an issue with the code below. When I click the button next to the canvas, my intention is to have a new window open displaying the canvas in full view. However, it's not working as expected. Can someone please assist me in troubleshooting this problem? Any help would be greatly appreciated. Thank you.

const openCanvasPopup = () => {
  const newWindow = window.open("", "_blank");
  if (newWindow) {
    let newCanvasElement = document.createElement('canvas');
    newCanvasElement.id = "canvasPopup";
    newCanvasElement.width = newWindow.innerWidth;
    newCanvasElement.height = newWindow.innerHeight;
    newWindow.document.body.appendChild(newCanvasElement);

    const newCanvas = new fabric.Canvas('canvasPopup');
    newCanvas.loadFromJSON(jsonData.value, () => {
      newCanvas.renderAll();
    });
  }
};

Successfully resolved the issue By omitting the ID, the element was able to pass through seamlessly If you have any insights on why this worked, please share

function launchCanvasPopup() {
  const newTab = window.open("", "_blank");
  if (newTab) {
    const newCanvasElement = document.createElement('canvas');
    newTab.document.body.appendChild(newCanvasElement);

    const newCanvas = new fabric.Canvas(newCanvasElement)

    newCanvas.loadFromJSON(jsonData.value, () => {
    });
  }
}

It appears that your code is on the right track, but there could be potential issues related to timing or scope. Here are some suggestions to help:

Confirm Fabric.js is properly loaded: Ensure that you have correctly included the Fabric.js library in the HTML of the new window by adding the script tag within the <head> section.
Wait for Window to Fully Load: Make sure that you wait for the new window's document to fully load before attempting any DOM manipulations. You can utilize the load event to ensure readiness before making any changes.

Below is an improved version of your code that waits for the new window to finish loading before adding the canvas element:

javascript
const openCanvasPopup = () => {
  const newWindow = window.open("", "_blank");

  if (newWindow) {
    newWindow.document.addEventListener('DOMContentLoaded', () => {
      const newCanvasElement = document.createElement('canvas');
      newCanvasElement.id = "canvasPopup";
      newCanvasElement.width = newWindow.innerWidth;
      newCanvasElement.height = newWindow.innerHeight;
      newWindow.document.body.appendChild(newCanvasElement);

      const newCanvas = new fabric.Canvas('canvasPopup');
      newCanvas.loadFromJSON(jsonData.value, () => {
        newCanvas.renderAll();
      });
    });
  }
};

By listening for the DOMContentLoaded event on the new window's document, you ensure that it's fully loaded before making any DOM changes.

If problems persist, check your browser console for error messages that may shed light on the issue.
