Question

I just started building a Chrome extension, but I’m not sure how everything works.
I want to get a string of data in one method (getTabs) and then return it to the method that called it.
This code calls getTabs which creates a string and tries to return it.

function emailTabs() {  
chrome.tabs.getAllInWindow(null, getTabs);
console.log(data); //this is never able to access the string
}

function getTabs(tabs) {
  var data='';
  //build up data... 
  console.log(data); //this works when there's no anonymous function
  return data;
}

How do I get that string back in the emailTabs?

Answer 1

Assuming that getTabs return something, you can create an anonymous function in getAllInWindow to gain more control over it, then catch the value with something like this :

function emailTabs() {
    chrome.tabs.getAllInWindow(null, function(tabs){
        var str = getTabs(tabs);
        // some code using the string
    });
}
