Steps to reproduce the problem:
1.Store any value in global variable of chrome extension javascript 
2.Access it in the method  "chrome.tabs.executescript"
3.You cant access it. 

What is the expected behavior?
You should be able to access global variables in the same javascript defined outside, into "chrome.tabs.executescript" method.

My Code Below :

Step 1 :

chrome.extension.onRequest.addListener(
    function (request, sender, sendResponse) {
        parser = new DOMParser();
        htmlDoc = parser.parseFromString(request.content, "text/html");

        //outputJson is a global variable which is Populated here
        outputJson = parseMyPage(outputJson, htmlDoc);

    });

Step 2:

chrome.tabs.getSelected(null, function (tab) {
    // Now inject a script onto the page
    chrome.tabs.executeScript(tab.id,{
        code: "chrome.extension.sendRequest({content: document.body.innerHTML}, function(response) { console.log('success'); });"
    }, function () {

       //my code to access global variables
if (outputJson && null != outputJson) {
    // other stuff
}

    });
});

What went wrong?
The value in the variable is empty when I try to access it inside "chrome.tabs.executescript"
