This code isn't working, how do I fix it?

Question

function myFunction() {

   alert(window[title]);

}
myFunction();

I'm expecting to this see the html the title page.

Answer 1

First off, title doesn't belong to window. It belongs to document.

Secondly, you've mixed dot notation and array indexer notation, you either need:

alert(document['title']);

Or:

alert(document.title);

Unless, of course, you have a variable called title that holds the string 'title', in which case it would look something like:

var title = 'title';
alert(document[title]);

Answer 2

function myFunction() {

   alert(document.title);

}

First off, window[title] will make javascript look for the undeclared variable title; you probably meant window['title']. Second you want document.title
