`for key of object`

Try it in [js2coffee](http://js2.coffee/)

`of` keyword:

    for key, value of obj

or to make sure you&#39;re only checking properties on this object (and not the prototype chain):

    for own key, value of obj

I have a service that does some work on an HttpServletRequest object, specifically using the request.getParameterMap and request.getParameter to construct an object.

I was wondering if there is a straightforward way to take a provided url, in the form of a string, say 

    String url = &quot;http://www.example.com/?param1=value1&amp;param&quot;;

and easily convert it to a HttpServletRequest object so that I can test it with my unit tests? Or at least just so that request.getParameterMap and request.getParameter work correctly?

I&#39;ve added several directories, libraries such as matlab, opencv, etc to compile my current C file in Visual Studio project.

All my upcoming projects will require the same setup/properties. Do I need to setup my each project&#39;s properties individually or I can do something to apply it to all ?

How can I use for (var key in object) in CoffeeScript? It compiles to...

    for (_i = 0, _len = object.length; _i &lt; _len; _i++) {
        key = object[_i];

...but I just want to iterate though an object.

I disable the button like this on my jQuery Mobile webpage:

    $(document).ready(function() {
        $(&quot;#deliveryNext&quot;).button();
        $(&quot;#deliveryNext&quot;).button(&#39;disable&#39;);
    });

and i can enable it with

    $(&quot;#deliveryNext&quot;).button(&#39;enable&#39;);

But how do i check if the button is disabled or enabled? 

This command gives &quot;undefined&quot;:

    $(&quot;#deliveryNext&quot;).attr(&#39;disabled&#39;)

Some ideas?

Edit: i find out that $(&quot;#deliveryNext&quot;).button(&#39;disable&#39;) only seams to change the style on the button, the clicking works fine after so i need to disable the button some how also.. i tried .attr(&#39;disabled&#39;, &#39;disabled&#39;) but when i then test .attr(&#39;disabled&#39;) i get undefined... 

Edit2: more about my &quot;real&quot; problem at https://stackoverflow.com/questions/6438659/how-to-disable-a-link-button-in-jquery-mobile

Looking at an online source code I came across this at the top of several source files.

    var FOO = FOO || {};
    FOO.Bar = …;

But I have no idea what `|| {}` does.

I know `{}` is equal to `new Object()` and I think the `||` is for something like &quot;if it already exists use its value else use the new object.

Why would I see this at the top of a source file?


What does &quot;var FOO = FOO || {}&quot; (assign a variable or an empty object to that variable) mean in Javascript?

It&#39;s difficult to explain the case by words, let me give an example:

    var myObj = {
        &#39;name&#39;: &#39;Umut&#39;,
        &#39;age&#39; : 34
    };

    var prop = &#39;name&#39;;
    var value = &#39;Onur&#39;;

    myObj[name] = value; // This does not work

    eval(&#39;myObj.&#39; + name) = value;   //Bad coding ;)

I&#39;d like to be able to convert specific textareas on a page to be ACE editors.

Does anyone have any pointers please?

EDIT:

I have the the editor.html file working with one textarea, but as soon as I add a second, the second isn&#39;t converted to an editor.

EDIT 2:

I decided to scrap the idea of having several, and instead open one up in a new window. My new predicament is that when I hide() and show() the textarea, the display goes awry. Any ideas?

How do I make a textarea an ACE editor?

How do I use a javascript regular expression to check a string that does not match certain words?

For example, I want a function that, when passed a string that contains either `abc` or `def`, returns false.

&#39;abcd&#39; -&gt; false

&#39;cdef&#39; -&gt; false

&#39;bcd&#39; -&gt; true

**EDIT**

Preferably, I want a regular expression as simple as something like, [^abc], but it does not deliver the result expected as I need consecutive letters. 

eg. I want `myregex`

    if ( myregex.test(&#39;bcd&#39;) ) alert(&#39;the string does not contain abc or def&#39;);

The statement `myregex.test(&#39;bcd&#39;)` is evaluated to `true`.

Please tell me how to write javascript below in coffeescript.

I want to pass two anonymous functions as arguments for jQuery&#39;s hover, like so:

    $(&#39;element&#39;).hover(
      function() {
        // do stuff on mouseover
      },
      function() {
        // do stuff on mouseout
      }
    );

It&#39;s easy with just one – `hover -&gt;` – but what is the proper syntax in CoffeeScript for two? I tried `...hover -&gt;`, `...hover( -&gt;...`, etc. but nothing gets me the above structure.

How to pass two anonymous functions as arguments in CoffeScript?

I notice that in CoffeeScript, if I define a function using:

    a = (c) -&gt; c=1

I can only get the **function expression**:

    var a;
    a = function(c) {
        return c = 1;
    };

But, personally I often use **function declaration**,for example:

    function a(c) {
        return c = 1;
    }

I do use the first form, but I&#39;m wondering if there is a way in CoffeeScript generating a function declaration. If there is no such way, I would like to know why CoffeeScript avoid doing this. I don&#39;t think JSLint would holler an error for declaration, as long as the function is declared at the top of the scope.

If I had a complex if statement that I did not want to overflow simply for aesthetic purposes, what would be the most kosher way to break it up since coffeescript will interpret returns as the body of the statement in this case?

    if (foo is bar.data.stuff and foo isnt bar.data.otherstuff) or (not foo and not bar)

How do I properly format long compound if statements in Coffeescript

I have a REST Json API that returns a list &quot;logbooks&quot;. There are many types of logbooks that implement different but similar behavior. The server side implementation of this on the Database layer is a sort of Single Table Inheritance, so each JSON representation of a logbook contains its &quot;type&quot; :

    [
      {&quot;type&quot;: &quot;ULM&quot;, &quot;name&quot;: &quot;My uml logbook&quot;, ... , specific_uml_logbook_attr: ...},
      {&quot;type&quot;: &quot;Plane&quot;, &quot;name&quot;: &quot;My plane logbook&quot;, ... , specific_plane_logbook_attr: ...}
    ]


I would like to replicate this server model on the client side, so I have a base `Logbook` class and multiple logbook sub classes :

    class Logbook extends Backbone.Model

    class UmlLogbook extends Logbook

    class PlaneLogbook extends Logbook

    ...

My `Backbone.Collection` is a set of `Logbook` models that i use to query the JSON API :

    class LogbookCollection extends Backbone.Collection
      model: Logbook
      url: &quot;/api/logbooks&quot;

When I fetch the logbook collection, is there a way to cast each `Logbook` to its corresponding sub class (based on the JSON &quot;type&quot; attribute) ?
