Trying to log this javascript variable in Applescript but its logging as (missing value)

Question

tell application "Google Chrome" set myVar to execute Javascript "document.getElementsByTagName('input')" log "did it" log myVar end tell

The result of your javascript is a complex type, and if you can update it to return a scalar value, Would be weird to try and return a JSON object to Applescript. I can give you a code snippet to make it work for scalar value. — user3579815

I am trying to get a list of all the input elements on a webpage. Is there anyway I can do that with AppleScript? Perhaps parse the JSON? — Kiyana Dunlock

You could probably serialize the JSON object into a string, pass it back to AppleScript, then deserialize it into an array of records. — user3579815

As mentioned, if you could replace the result with a scalar value, like read an attribute or value of an HTML element, you could do:

tell application "Google Chrome"
    set myVar to execute tab 1 of window 1 javascript "1"

    log "did it"
    log myVar
end tell

For simplicity, it is just returning the 1 literal. You can change the javascript code that returns a scalar value like: document.getElementById('someId').value
