You can **get** the document.URL, but you **can not set** it. 
You can both get and set the `location.href`.

In some webbrowsers, you are able to set the `document.URL` but please don&#39;t, as it doesn&#39;t work in most browsers.

You gave the answer yourself!

    var currentURL = document.URL;
    alert(currentURL);

They&#39;re interchangeable as far as getting data is concerned, but as you pointed out document.URL can not be set.  I just always use location.href since it&#39;s a getter/setter.

Yes and no!  

    alert(document.url);  
    document.url=&quot;http://www.google.co.uk&quot;;  
    alert(document.url);  



Is there a way to combine two decorators into one new decorator in python?

I realize I can just apply multiple decorators to a function, but I was curious as to whether there&#39;s some simple way to combine two into a new one.


Can I combine two decorators into a single one in Python?

I have a Python list which holds pairs of key/value:

    l = [[1, &#39;A&#39;], [1, &#39;B&#39;], [2, &#39;C&#39;]]

I want to convert the list into a dictionary, where multiple values per key would be aggregated into a tuple:

    {1: (&#39;A&#39;, &#39;B&#39;), 2: (&#39;C&#39;,)}

The iterative solution is trivial:

    l = [[1, &#39;A&#39;], [1, &#39;B&#39;], [2, &#39;C&#39;]]
    d = {}
    for pair in l:
        if pair[0] in d:
            d[pair[0]] = d[pair[0]] + tuple(pair[1])
        else:
            d[pair[0]] = tuple(pair[1])
    
    print(d)

    {1: (&#39;A&#39;, &#39;B&#39;), 2: (&#39;C&#39;,)}

Is there a more elegant, Pythonic solution for this task?

I know that `document.URL` can not be set, while `location.href` can.

But the Document indicates:
 
&gt; URL is a replacement for the DOM Level 0 `location.href` property.

So when would we use `document.URL`?

I&#39;m making a javascript app which retrieves `.json` files with jquery and injects data into the webpage it is embedded in.

The `.json` files are encoded with UTF-8 and contains accented chars like &#233;, &#246; and &#229;.

The problem is that I don&#39;t control the charset on the pages that are going to use the app.

Some will be using UTF-8, but others will be using the iso-8859-1 charset. This will of course garble the special chars from the `.json` files.

How do I convert special UTF-8 chars to their iso-8859-1 equivalent using javascript?

Maybe pretty easy question. 


Where should I use `var` keyword in JavaScript. It seems to me using it or not have the same effect ( but of course I&#39;m still learning the language ) 


For instance these both seems the same to me:
 
    (function(){
      var a = &quot;mundo&quot;
      alert(&quot;Hola, &quot; + a )
    })()

and 

    (function(){
      a = &quot;mundo&quot;
      alert(&quot;Hola, &quot; + a )
    })()

But of course there must be a more complex example where the difference shows up.

In Firefox **3**, I was able to write a custom confirmation popup with:

    window.onbeforeunload = function() {
       if (someCondition) {
          return &#39;Your stream will be turned off&#39;;
       }
    }

Now in Firefox **4**, it does not show my custom message. The default message that it provides is not even accurate to what my application does.

Can this default message be overridden?

[w3fools][1] claims that URLs can contain spaces: http://w3fools.com/#html_urlencode

Is this true? How can a URL contain an un-encoded space?

I&#39;m under the impression the [request line of an HTTP Request][2] uses a space as a delimiter, being formatted as `{the method}{space}{the path}{space}{the protocol}`:

    GET /index.html http/1.1

Therefore how can a URL contain a space? If it can, where did the practice of replacing spaces with `+` come from?

Spaces in URLs?

I&#39;m designing a public API to my company&#39;s data. We want application developers to sign up for an API key so that we can monitor use and overuse.

Since the API is REST, my initial thought is to put this key in a custom header. This is how I&#39;ve seen Google, Amazon, and Yahoo do it. My boss, on the other hand, thinks the API is easier to use if the key becomes merely a part of the URL, etc. &quot;http://api.domain.tld/longapikey1234/resource&quot;. I guess there is something to be said for that, but it violates the principle of the URL as a simple address of what you want, and not how or why you want it.

Would you find it logical to put the key in the URL? Or would you rather not have to manually set HTTP headers if writing a simple javascript frontend to some data?

What&#39;s the simplest way to get the String representation of a XML Document (`org.w3c.dom.Document`)? That is all nodes will be on a single line.

As an example, from

    &lt;root&gt;
      &lt;a&gt;trge&lt;/a&gt;
      &lt;b&gt;156&lt;/b&gt;
    &lt;/root&gt;

(this is only a tree representation, in my code it&#39;s a `org.w3c.dom.Document` object, so I can&#39;t treat it as a String)

to

    &quot;&lt;root&gt; &lt;a&gt;trge&lt;/a&gt; &lt;b&gt;156&lt;/b&gt; &lt;/root&gt;&quot;

Thanks!

What&#39;s the easiest way to determine an elements position relative to the document/body/browser window? 

Right now I&#39;m using `.offsetLeft/offsetTop`, but this method only gives you the position relative to the parent element, so you need to determine how many parents to the body element, to know the position relaltive to the body/browser window/document position. 

This method is also to cumbersome.

How do you test an element for existence without the use of the `getElementById` method?

I have set up a [live demo][1] for reference. I will also print the code on here as well:

    &lt;!DOCTYPE html&gt;
    &lt;html&gt;
    &lt;head&gt;
        &lt;script&gt;
        var getRandomID = function (size) {
                var str = &quot;&quot;,
                    i = 0,
                    chars = &quot;0123456789abcdefghijklmnopqurstuvwxyzABCDEFGHIJKLMNOPQURSTUVWXYZ&quot;;
                while (i &lt; size) {
                    str += chars.substr(Math.floor(Math.random() * 62), 1);
                    i++;
                }
                return str;
            },
            isNull = function (element) {
                var randomID = getRandomID(12),
                    savedID = (element.id)? element.id : null;
                element.id = randomID;
                var foundElm = document.getElementById(randomID);
                element.removeAttribute(&#39;id&#39;);
                if (savedID !== null) {
                    element.id = savedID;
                }
                return (foundElm) ? false : true;
            };
        window.onload = function () {
            var image = document.getElementById(&quot;demo&quot;);
            console.log(&#39;undefined&#39;, (typeof image === &#39;undefined&#39;) ? true : false); // false
            console.log(&#39;null&#39;, (image === null) ? true : false); // false
            console.log(&#39;find-by-id&#39;, isNull(image)); // false
            image.parentNode.removeChild(image);
            console.log(&#39;undefined&#39;, (typeof image === &#39;undefined&#39;) ? true : false); // false ~ should be true?
            console.log(&#39;null&#39;, (image === null) ? true : false); // false ~ should be true?
            console.log(&#39;find-by-id&#39;, isNull(image)); // true ~ correct but there must be a better way than this?
        };
        &lt;/script&gt;
    &lt;/head&gt;
    &lt;body&gt;
        &lt;div id=&quot;demo&quot;&gt;&lt;/div&gt;
    &lt;/body&gt;
    &lt;/html&gt;

Basically the above code demonstrates an element being stored into a variable and then removed from the DOM. Even though the element has been removed from the DOM, the variable retains the element as it was when first declared. In other words, it is not a live reference to the element itself, but rather a replica. As a result, checking the variable&#39;s value (the element) for existence will provide an unexpected result.

The `isNull` function is my attempt to check for an elements existence from a variable, and it works, but I would like to know if there is an easier way to accomplish the same result.

PS: I&#39;m also interested in why JavaScript variables behave like this if anyone knows of some good articles related to the subject.

I have:

Which one of these is the most effective vs checking if the user agent is accessing via the correct domain.

We would like to show a small js based &#39;top bar&#39; style warning if they are accessing the domain using some sort of web proxy (as it tends to break the js).

We were thinking about using the following:

    var r = /.*domain\.com$/;
    if (r.test(location.hostname)) {
        // showMessage ...
    }

That would take care of any subdomains we ever use.

Which should we use host or hostname?

In Firefox 5 and Chrome 12:

    console.log(location.host);
    console.log(location.hostname);

.. shows the same for both.

Is that because the port isn&#39;t actually in the address bar?

[W3Schools][1] says host contains the port.

**Should location.host/hostname be validated or can we be pretty certain in IE6+ and all the others it will exist?**
