Accessing variables from a webpage using the console in Chrome

Suppose I have a webpage that contains a set of JavaScript variables like this:

const pageId = 1
const pageName = "pName"

Is it feasible for me to access these variables directly from the console window?

Instead of modifying the page code to log the variables, such as:

console.log(pageId)

I am interested in executing the page as is and then using the Chrome developer tools, specifically the console tab, to display the value of any variable I select.

Is this achievable?

Answer №1

When working with the Console, it operates within the same scope as the JS engine. If the constants are global, you can simply access them by using their name as usual.

However, if the constants are not global, you will only be able to access them by moving into the correct scope, such as setting a breakpoint within the same function.
