Invoking a function without specifying its parent function when nested within another function

Question

Invoking a function without specifying its parent function when nested within another function

I need to execute an anonymous function within another function without actually calling the parent function, as it will lead to errors.

Here is the parent function:

function onloadCallback() {
  grecaptcha.render("recaptchaHolder", {
    "size": "invisible",
    "sitekey": "1Lcsvh53yhsd5312hhsg554dfhs098bbeyi_Hv",
    "callback": function(resp) {
      $("zendesk-ticketing-form").attr("grecaptcha", resp)
    }
  });
}

The function I want to call is:

function(resp){$("zendesk-ticketing-form").attr("grecaptcha",resp)}

I am working with Java Selenium for this task.

I attempted the following:

 js.executeScript("onloadCallback()(\"" + responseToken + "\")");

but this results in an error because it calls onloadCallback (the parent function) before accessing the internal anonymous function.

Any suggestions on how to achieve this?

Answer №1

If you want to invoke a function in a particular context, one way to achieve this is by moving the function to the outer scope and then utilizing it both internally and globally.

Imagine a scenario where:

function a() {
  b('some-name', {
    foo: 1,
    bar: 2,
    c: function(a, b) {
      console.log('i was finally called', a, b);        
    }
  })
}

// transform it like this

function functionForC(a, b) {
  console.log('i was finally called', a, b);        
}

function a() {
  b('some-name', {
    foo: 1,
    bar: 2,
    c: functionForC
  })
}

To maintain your current functionality while easily accessing functionForC(), it's advisable to move the function out of the original function's scope and reference it inside as demonstrated below:

This method ensures that your existing functionality remains intact and allows direct access to functionForC().
