Although my knowledge of javascript is quite limited, I have a strong interest in creating a script that requires data from another webpage. Is there a javascript alternative to urllib2 that can handle simple GET requests without the need for cookie storage or anything overly complex?
One option is the XMLHttpRequest, however, it is restricted to the same domain of your website due to the Same Origin Policy.
If you are looking for ways to bypass the Same Origin Policy, you can read this Stack Overflow post:
UPDATE:
Below is a simple (not cross-browser) example:
var xhr = new XMLHttpRequest();
xhr.open('GET', '/questions/3315235', true);
xhr.onreadystatechange = function() {
if (xhr.readyState === 4) {
console.log(xhr.responseText);
}
};
xhr.send(null);
If you execute the above code in Firebug, while having Stack Overflow open, you will see the HTML of this question displayed in your JavaScript console:

An option is to send an AJAX request and handle the response.
If you want to collect data from websites, consider creating your own server that can run scripts to retrieve the information for you. Then, simply request your server to fetch the data and send it back to your web page.
