org.openqa.selenium.JavascriptException: javascript error: window.testSpread.getActiveSheet is not a function

Question

I'm trying to access the spreadjs canvas for one of my automation project with selenium java

This is code snippet I'm using for the same

URL: https://developer.mescius.com/spreadjs/demos/features/table-sheet/overview/purejs

JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("window.testSpread = new GC.Spread.Sheets.findControl(document.querySelector(\"[gcuielement=\'gcWorksheetCanvas\']\"))");
Object value = js.executeScript("return window.testSpread.getActiveSheet().getValue(0,0,);");

Getting the below error while running the code

org.openqa.selenium.JavascriptException: javascript error: window.testSpread.getActiveSheet is not a function

Answer 1

can you console.log the value of window.testSpread? also, note that findControl is a static function, no "new" spread = GC.Spread.Sheets.findControl(host);
